Kuronuma (Godzilla vs. Mechagodzilla)

Mechagodzilla (メカゴジラ,   Mekagojira) is a mecha that first appeared in the 1974 Godzilla film Godzilla vs. Mechagodzilla.

A robot monster built in Godzilla's image for the sole purpose of destroying him, Mechagodzilla has become one of Godzilla's most popular and recurring foes, along with King Ghidorah. To date, there have been six distinct incarnations of Mechagodzilla featured in the Godzilla franchise. The first version of the character was introduced in the 1974 film Godzilla vs. Mechagodzilla, where it was a creation of the evil Black Hole Planet 3 Aliens designed to destroy Godzilla and conquer Earth. This Mechagodzilla returned in Terror of Mechagodzilla, where it was rebuilt by its alien masters, renamed Mechagodzilla 2, made even more powerful than the original and fought alongside the monster Titanosaurus. Mechagodzilla was reintroduced for the Heisei series in the 1993 film Godzilla vs. Mechagodzilla II. This second version of Mechagodzilla was a weapon built by G-Force, a military branch of the United Nations, to defend mankind from Godzilla, and was constructed using technology reverse-engineered from the remains of Mecha-King Ghidorah. The third version of Mechagodzilla, more commonly known as Kiryu, first appeared in the film Godzilla Against Mechagodzilla in 2002. Like the Heisei Mechagodzilla, Kiryu was a human-built weapon, this time controlled by the JSDF. Kiryu was unique among all the Mechagodzillas in that he was a true cyborg, constructed around the skeleton of the first Godzilla that appeared in 1954. Kiryu was, however, susceptible to becoming possessed by the first Godzilla's spirit, leading him to act autonomously and run wild. Kiryu returned in the following film, Godzilla: Tokyo SOS, where he again did battle with Godzilla, this time with the assistance of Mothra and her twin larvae. A fourth version of Mechagodzilla made a brief appearance in GODZILLA: Planet of the Monsters, and returned in the second film in the GODZILLA anime trilogy. This Mechagodzilla was constructed by human and Bilusaludo scientists under the United Earth in order to destroy Godzilla Earth. Unfortunately, Mechagodzilla was lost before it could be activated when Godzilla Earth destroyed its production facility in Hamamatsu in 2046. However, the machine's head remained intact, and over the next 20,000 years, its Nanometal expanded and proliferated, gradually forming a replica of its development facility dubbed Mechagodzilla City. The character also appeared as the main antagonist of the fourth film of Legendary Pictures and Warner Bros.' Monsterverse series, Godzilla vs. Kong, designed by Apex Cybernetics to overthrow Godzilla as the planet's apex predator. Outside of the Godzilla series, Mechagodzilla made an appearance in the 2018 film adaptation of Ready Player One. This is an overview page. To view information on specific incarnations of Mechagodzilla, please click on their corresponding boxes in the table below.


The name "Mechagodzilla" comes from "mecha," which is derived from the word "mechanical," and Godzilla's name. In Terror of Mechagodzilla, the rebuilt Mechagodzilla is known as Mechagodzilla 2 (メカゴジラ2,   Mekagojira Tsū).

The Heisei Mechagodzilla's official designation is UX-02-93. When this Mechagodzilla combines with the warship Garuda, it becomes known as Super Mechagodzilla (スーパーメカゴジラ,   Sūpā Mekagojira).

The Millennium Mechagodzilla is known as Kiryu (機龍,   Kiryū), which means "Machine Dragon" in Japanese. Kiryu's full title is Multipurpose Fighting System Type-3 (3式多目的戦闘システム,   San-Shiki Tamokuteki Sentō Shisutemu), abbreviated as MFS-3. In Godzilla: Tokyo SOS, Kiryu is repaired and upgraded as Modified Type-3 Kiryu (3式機龍改,   San-Shiki-Kiryū Aratame).

The anime Mechagodzilla's official designation by the Bilusaludo is Anti-Godzilla Super Heavy Mass Nanometal Decisive Battle Weapon: Mechagodzilla (対ゴジラ超重質量ナノメタル製決戦兵器:メカゴジラ,   Tai Gojira Chō Omo Shitsuryō Nanometaru-sei Kessen Heiki: Mekagojira), while it is typically abbreviated to just "Mechagodzilla" or MG.[4] Mechagodzilla was called the "Last Hope of Mankind" (人類最後の希望,   Jinrui Saigo no Kibō) when its existence was revealed to the public by the United Earth, and it is referred to as such in the tagline for GODZILLA: City on the Edge of Battle. After its Nanometal spread and rebuilt its production facility around it, Mechagodzilla became the core of a colossal mechanized fortress called Mechagodzilla City (メカゴジラシティ,   Mekagojira Shiti).

The Monsterverse Mechagodzilla is simply referred to as "the Mecha" by Apex Cybernetics, but the character Josh Valentine refers to it at one point as "Mechagodzilla."

While "Mechagodzilla" is the official trademarked English name for the character, it is also frequently spelled as MechaGodzilla, Mecha Godzilla or Mecha-Godzilla.

The Mechagodzilla incarnations vary greatly in appearance, but all of them share some common traits. The first three versions of Mechagodzilla are giant robots modeled after Godzilla, with silver-colored bodies, orange or yellow eyes, and a weapon port on their torsos. The Heisei and Millennium Mechagodzillas are both taller than Godzilla, while the Showa version is the same height as he is. The Mechagodzillas tend to have smaller dorsal fins than Godzilla, as well as a shorter tail. Only Kiryu and the Monsterverse Mechagodzilla possess a full-length movable tail. The anime Mechagodzilla looks considerably different, with a segmented body covered in large spikes. Its head is flat and elongated, with red eyes and two large spikes protruding from its face that resemble tusks and a smaller spike jutting from its chin. The Monsterverse Mechagodzilla is considerably thinner than previous versions of the character. It supports three rows of small, square-shaped dorsal fins with red lights at each tip that travel from its head to its back, which then converge into one row as they move down its tail. Its arms and hands are noticeably larger and thicker than those of previous incarnations, with its hands resembling giant crane claws.


The Showa Mechagodzilla is a battle machine constructed by the Black Hole Planet 3 Aliens following close study of the real Godzilla. With their home planet on the verge of being sucked into a black hole, the Black Hole Planet 3 Aliens traveled to Earth and built Mechagodzilla in an attempt to conquer the planet for their race so they could live on it. Initially, Mechagodzilla wore a fake skin that disguised it as Godzilla. After Mechagodzilla was destroyed by Godzilla, it was rebuilt by the aliens the following year, now named Mechagodzilla 2 and now even more powerful than before.

The Heisei Mechagodzilla is a weapon constructed by G-Force, the anti-Godzilla military branch of the United Nations. After G-Force's first anti-Godzilla weapon, the Garuda, was deemed too weak, G-Force salvaged the severed mechanical middle head of Mecha-King Ghidorah, a cyborg from the future, and studied the advanced technology recovered from it to build Mechagodzilla.

Kiryu is a bio-robot constructed by the Anti-Megalosaurus Force, a branch of the JSDF specializing in fighting kaiju, to combat Godzilla. Kiryu is constructed around the skeleton of the first Godzilla, who was killed by the Oxygen Destroyer in 1954. Kiryu was programmed with special "DNA computers" designed to make it operate, like an organic creature, although the DNA sequence used in these computers had the unintended effect of leaving Kiryu susceptible to the sound of Godzilla's roars, which initially reawakened the first Godzilla's spirit and caused Kiryu to go berserk.

The anime Mechagodzilla was constructed in secret by humanity and the Bilusaludo in Hamamatsu, Japan from 2042 to 2046, with the intention of it being the ultimate anti-Godzilla weapon. It was constructed using Nanometal, an advanced autonomous metal developed by Bilusaludo scientists. Godzilla arrived in Hamamatsu in March of 2046 and engaged in a final decisive battle with the United Earth. Despite being completed, Mechagodzilla would not activate for unknown reasons, and the Bilusaludo engineers were forced to evacuate the facility and abandon it. Godzilla was triumphant in the battle, and Mechagodzilla was presumed lost, with the United Earth organizing an Earth evacuation plan after their latest defeat.[10] However, its head was left intact, and with its A.I. still partially active and its Nanometal limiter disabled it began gradually forming a replica of its production facility around itself.

The Monsterverse Mechagodzilla was also constructed in secret by Apex Cybernetics to destroy Godzilla and end the reign of the Titans. At some point during the five years after Godzilla defeated King Ghidorah, Apex had purchased the skull from Ghidorah's severed left head from Alan Jonah and connected its neural networks to Mechagodzilla.[11] Bernie Hayes theorized that Apex Cybernetics placed a second Ghidorah skull inside Mechagodzilla to take full advantage of the Titan's telepathic abilities, while the film's novelization shows Walter Simmons purchasing two skulls from Jonah. Neither version of the story explains the origin of the second skull.


Showa era

Inspired by Mechani-Kong, King Kong's mechanical doppelganger which had been featured in the 1967 film King Kong Escapes, Toho conceptualized Mechagodzilla as Godzilla's foe for the 14th entry in the series, commemorating its 20th anniversary. Godzilla vs. Mechagodzilla proved particularly successful, inspiring Toho to feature Mechagodzilla in the next film, Terror of Mechagodzilla.

Godzilla vs. Mechagodzilla to Terror of Mechagodzilla

Main article: Mechagodzilla (Showa).

Intending to conquer the Earth in order to establish a new technological utopia with their home planet's final day approaching, the Black Hole Planet 3 Aliens realized that they required a suitable weapon to not only annihilate the existing human civilization, but eliminate the native kaiju who frequently repelled other alien invaders. Following close study of the Earth's most powerful defender, Godzilla, the aliens developed a weapon in his image: Mechagodzilla. In order to conceal their invasion from the humans for as long as possible, the aliens disguised Mechagodzilla as the real Godzilla using a false skin, then unleashed him on Japan. Anguirus, Godzilla's most loyal friend and ally, immediately saw through the robot's disguise and attacked it, but was brutally beaten and had his jaw broken. Before retreating, Anguirus managed to call out to the real Godzilla, who intercepted his impostor in Tokyo. Godzilla exposed the fake Godzilla's disguise, prompting alien leader Kuronuma to have the machine remove it and unleash its full arsenal. Mechagodzilla's weapons proved formidable, seemingly killing Godzilla, but the control mechanism in the mecha's head was damaged in the battle. Kuronuma recalled Mechagodzilla to the aliens' base in Okinawa, but he realized that the damage was so extensive that his men did not have the technological expertise to repair it on schedule. The aliens abducted Professor Hideto Miyajima, a human scientist familiar with extraterrestrial technology, and forced him to repair Mechagodzilla in exchange for his daughter's life. Kuronuma launched the repaired Mechagodzilla to destroy Okinawa's guardian monster King Caesar, who had recently been awakened by a group of humans privy to the invaders' plans. Mechagodzilla nearly killed King Caesar, but Godzilla soon arrived for a rematch. Mechagodzilla was able to hold the monsters at bay for a while, but Godzilla called upon his newfound magnetic powers to trap Mechagodzilla, after he which he and King Caesar badly damaged it. Godzilla twisted off his mechanical double's head, and its wreckage self-destructed soon afterward along with its alien masters' base.

Mechagodzilla 2 and Titanosaurus battle Godzilla in Terror of Mechagodzilla

Shortly after the failure of Kuronuma and his men, the Black Hole Planet 3 Aliens sent another invasion force headed by Mugal to conquer the Earth. The aliens salvaged the wreckage of Mechagodzilla and brought it to their base under Mount Amagi to be rebuilt. They called upon Dr. Shinzo Mafune, a deranged misanthropic human scientist whom they had helped years before by saving his daughter Katsura following a laboratory accident, to help them complete and perfect the rebuilt Mechagodzilla 2. Furthermore, Mafune granted the aliens the services of the dinosaur monster Titanosaurus, who was under his control due to a device he had invented. Mafune was later horrified to learn that the aliens had installed the control device for Mechagodzilla inside of his daughter, who had been converted into a cyborg by the aliens' doctors following her earlier injury. After all, Mugal explained, Mafune had said earlier that Mechagodzilla required superior living brain tissue in order to be a perfect robot. The aliens deployed Mechagodzilla 2 and Titanosaurus to destroy Tokyo, but they were soon confronted by Godzilla. This time, with the odds against him, Godzilla stood no chance against his foes and was beaten into submission and buried alive in a ravine. However, INTERPOL utilized a sonic wave oscillator which interfered with the control device Mafune had installed inside Titanosaurus' brain, taking him out of the fight and allowing Godzilla to recover. Godzilla got close to Mechagodzilla and succeeded in tearing off its head. This time though, the mech had a secondary laser firing apparatus installed underneath its head. It floored Godzilla with several concentrated blasts, but was rendered inoperable when Katsura committed suicide and destroyed its control device. Godzilla used the opportunity to throw Mechagodzilla into the ravine where he had just been buried, then obliterated it once and for all with his atomic breath.

Heisei era

Having just successfully reintroduced popular Godzilla enemies King Ghidorah and Mothra in the new Heisei cycle of films, Toho chose to do the same with Mechagodzilla. Several different concepts were considered for this new version of the character, but the final onscreen product reinterpreted Mechagodzilla as a robot constructed by the United Nations in order to defend humanity from Godzilla. Toho considered featuring a rebuilt Mechagodzilla as Godzilla's ally in the following film, but instead opted to use a redesigned Moguera for this role. Outside of films, the Showa version of Mechagodzilla appeared in the 1996 Get Going! Godzilland OVAs, while the Heisei version appeared in the 1997 show Godzilla Island along with Black Mechagodzilla, a recolored version of the Showa Mechagodzilla, and Fake Godzilla, this time an individual character rather than a disguise for Mechagodzilla.

Godzilla vs. Mechagodzilla II

Main article: Mechagodzilla (Heisei).

In the wake of Godzilla's latest attack in 1992, the United Nations formed the U.N.G.C.C., a branch devoted to combating the threat he posed to humanity. The U.N.G.C.C.'s first anti-Godzilla weapon was an advanced aircraft called the Garuda, but it was deemed insufficient to combat Godzilla due to its limited firepower. After salvaging the remains of Mecha-King Ghidorah, the U.N.G.C.C. reverse-engineered its advanced Futurian technology in order to create its own anti-Godzilla robot. The new machine, dubbed Mechagodzilla, was a massive robot built in Godzilla's image, possessing a vast array of weaponry and designed to counter all of Godzilla's attacks and even turn them against him. In 1994, shortly after Mechagodzilla's completion, Godzilla came ashore at Yokkaichi and made his way to Kyoto, intent on recovering an infant Godzillasaurus who had been brought there by a group of scientists. Under the command of the U.N.G.C.C.'s military team G-Force, Mechagodzilla intercepted Godzilla in the countryside and quickly overwhelmed him. As the mech electrocuted Godzilla with its Shock Anchors, the King of the Monsters used a nuclear pulse to reverse the flow of energy back to his opponent, causing Mechagodzilla to short-circuit. Godzilla knocked Mechagodzilla aside and continued on his path to Kyoto, though he returned to the sea when he could not locate BabyGodzilla.

Mechagodzilla underwent extensive repairs, with original Garuda pilot Kazuma Aoki convincing lead Mechagodzilla engineer Leo Asimov to improve Garuda's capabilities and allow the two mechs to combine with each other. G-Force found a breakthrough in combating Godzilla after studying BabyGodzilla's anatomy, determining that the Godzillasaurus species required a secondary brain to control motor function in its lower body. G-Force attempted to transport Baby to the Ogasawara Islands, hoping to lure Godzilla there and use Mechagodzilla to target Godzilla's secondary brain and render him helpless. However, Baby's surrogate brother Rodan intercepted the transport and brought Baby and his adoptive mother Azusa Gojo to the Makuhari Bay area. Mechagodzilla and the Garuda headed there to deal with Rodan, with Mechagodzilla mortally wounding Rodan by blasting a hole through his chest. The victory was short-lived, as Godzilla soon emerged from the bay to challenge his robotic duplicate to a final battle. Godzilla withstood Mechagodzilla's onslaught and damaged it in close quarters, but the Garuda distracted him long enough for Mechagodzilla to recover. Mechagodzilla and the Garuda then combined into Super Mechagodzilla, utilizing the new G-Crusher system to paralyze Godzilla. Before Mechagodzilla could finish him off, Baby called to Rodan to save Godzilla. Rodan used the last of his strength to imbue Godzilla with his life energy, regenerating his secondary brain and temporarily increasing the power of his nuclear pulse and atomic breath. In this enraged and empowered state, Godzilla made short work of Mechagodzilla, melting its armor plating and destroying it with several blasts of his red spiral heat ray. Though the mech was obliterated, all of its crew managed to survive.

Get Going! Godzilland

Main article: Mechagodzilla (Showa).

Mechagodzilla was a resident of Godzilland, but was incredibly lonely and jealous of Godzilla due to the latter having many friends. On two occasions, Mechagodzilla attempted to abduct one of Godzilla's friends and force them to be his friend instead. Mechagodzilla kidnapped Godzilla's best friend Anguirus after a fight between him and Godzilla, and another time abducted Gojirin, on whom Godzilla had a crush. Each time, Mothra, Rodan, and Baragon helped Godzilla rescue his friend from Mechagodzilla, who forced Godzilla to solve several math problems before freeing his friend. Mechagodzilla stormed off in tears each time, but was eventually comforted by Mothra, who convinced Godzilla and his friends to play with Mechagodzilla.

Godzilla Island

Main articles: Mechagodzilla (Heisei), Black Mechagodzilla, Fake Godzilla.

G-Guard, the human military organization overseeing Godzilla Island, employed a team of robots to defend the island and its residents, which included Mechagodzilla, Moguera, and several Jet Jaguar units. G-Guard's Mechagodzilla frequently assisted Godzilla and his allies against the invading Xiliens and their legion of monster minions. The Xiliens employed their own Mechagodzilla, dubbed Black Mechagodzilla, in their repeated attempts to invade Godzilla Island. The Xiliens also constructed a Fake Godzilla robot which they used to try to frame Godzilla and make G-Guard turn against him. Fortunately, the real Godzilla quickly exposed and destroyed the impostor.

Millennium era

Following the box office success of 2001's Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack, Toho opted to revive Mechagodzilla as Godzilla's opponent for the following film. Godzilla Against Mechagodzilla proved successful as well, resulting in the character's return in Godzilla: Tokyo SOS, the only direct sequel to a prior Millennium Godzilla film.

Godzilla Against Mechagodzilla to Godzilla: Tokyo SOS

Main article: Kiryu.
Kiryu swings Godzilla through the air by the tail in Godzilla Against Mechagodzilla

When a second Godzilla attacked Tateyama in 1999, the Japanese government used the recently recovered skeletal remains of the original Godzilla as the basis for a new anti-kaiju weapon. This weapon, a bio-robot dubbed Kiryu, was completed in 2003, armed with highly advanced weaponry including the deadly Absolute Zero Cannon, capable of freezing targets to a temperature of 0 kelvin and smashing their atoms in the process. Kiryu's activation drew Godzilla to Japan, with the Anti-Megalosaurus Force deploying the cyborg to engage Godzilla near Yokohama. Kiryu's onslaught drove Godzilla back, but before he could finish him with the Absolute Zero, Godzilla let out a roar that reawakened the consciousness of the original Godzilla still attached to the bones inside of Kiryu. Kiryu promptly went berserk, firing at the AC-3 White Herons escorting him and destroying the surrounding city. The AMF was helpless to stop Kiryu's rampage, and could only wait until he exhausted his power supply. Kiryu's engineers managed to isolate the issue in the DNA computers controlling Kiryu, rendering him immune to running wild again. Despite the government's hesitation to launch Kiryu again, Prime Minister Hayato Igarashi was forced to give the launch order once Godzilla landed in Tokyo. Kiryu intercepted Godzilla before he could harm evacuating civilians, and the two monsters engaged in a fierce battle. Kiryu eventually subdued Godzilla, but just before he could fire the Absolute Zero, Godzilla knocked him over with his atomic breath, causing the weapon to misfire and vaporize several buildings. The blast rendered Kiryu inoperable from the White Herons, forcing his lead operator Akane Yashiro to enter him through a maintenance hatch and pilot him manually. Godzilla immediately fired his atomic breath at Kiryu as he tried to stand back up, knocking him down once more. Akane used all of her strength and willpower to get Kiryu to his feet again, with Lieutenant Susumu Hayama flying his White Heron directly into Godzilla's mouth to prevent him from firing at Kiryu again. Akane activated the Absolute Zero but flew Kiryu into Godzilla, pulling Hayama's White Heron out of Godzilla's mouth before carrying Godzilla into Tokyo Bay. The Absolute Zero fired underwater, producing a pillar of water which immediately froze and shattered after a few moments. Godzilla rose from the water, alive but bearing a gruesome wound on his chest. Kiryu soon surfaced behind him, badly damaged and out of power. Though Kiryu failed to kill Godzilla, Igarashi declared the fight a great victory, since Japan now had a weapon stronger than Godzilla.

Kiryu stands before the defeated Godzilla as Mothra's twin larvae encase the latter in silk in Godzilla: Tokyo SOS

In the ensuing year, the AMF performed repairs on Kiryu, replacing the arm he lost in the battle and replacing the damaged Absolute Zero Cannon with a Triple Hyper Maser Cannon. Akane Yashiro was sent to undergo special training in the United States, with a new team of operators placed in charge of Kiryu. The Shobijin from Infant Island appeared before their ally Shinichi Chujo, uncle of Kiryu's new lead mechanic Yoshito Chujo, and warned him that the use of the first Godzilla's remains to construct a weapon violated the natural order. If the remains were not returned to the sea, they said, Mothra would be forced to declare war on humanity. Chujo relayed the Shobijin's plea to Igarashi, promising that Mothra would defend Japan in Kiryu's place, but Igarashi said he could not scrap the project until Godzilla was destroyed. After sinking an American nuclear submarine in the waters around Guam, Godzilla returned to Tokyo. Chujo's grandson Shun called Mothra to Tokyo to fight Godzilla, but she was badly outmatched. Igarashi was forced to deploy Kiryu to aid Mothra, but he was disabled in the battle. Mothra's twin larvae hatched and swam to Tokyo to aid their mother, and carried on the fight once she was killed defending them. Yoshito entered Kiryu through a maintenance hatch and got the cyborg back online, but was trapped when Godzilla's heat ray warped the exit hatch. Kiryu exploited Godzilla's injury from the previous year's battle by reopening the wound on his chest with his new Spiral Claw. Sustained fire to the wound from Kiryu's Maser Cannons knocked Godzilla out of the fight, after which Mothra's larvae trapped him in silk. The AMF gave the order to Kiryu to finish Godzilla once and for all, but Godzilla's pained roars once again awakened the original Godzilla's consciousness within Kiryu. Rather than go berserk as before, Kiryu opted to save Godzilla and leave humanity in peace. He grabbed the helpless Godzilla and carried him over the ocean. In a final act, Kiryu automatically opened a hatch on his body that allowed Yoshito to escape. Just before diving into the water below, Yoshito saw a computer monitor display the words "SAYONARA YOSHITO." Kiryu crashed into the sea and deactivated as he sank to the bottom of the Japan Trench along with Godzilla.

Reiwa era

Mechagodzilla was featured as a major antagonist in the GODZILLA anime trilogy, reimagined as an alien superweapon composed of autonomous Nanometal. Though it only appears in its original form in brief flashback scenes in the first film, it is revealed to have proliferated into a massive Nanometal fortress dubbed "Mechagodzilla City" by the events of the second film.

GODZILLA: Planet of the Monsters to GODZILLA: City on the Edge of Battle

Main article: Mechagodzilla (anime trilogy).
Mechagodzilla sits unactivated in its hangar as Godzilla assaults the United Earth's base at the foot of Mount Fuji in GODZILLA: Planet of the Monsters

After approximately six years of unsuccessfully battling Godzilla in order to render their intended new home on Earth inhabitable, the Bilusaludo developed plans to construct a massive robotic weapon in Godzilla's image to destroy the creature once and for all. The robot, dubbed Mechagodzilla, was to be constructed from the experimental autonomous metal substance known as Nanometal in a development facility at the foot of Mount Fuji. Though the other member races of the United Earth, the Exif and the native humans, contributed to the project, Mechagodzilla was primarily overseen by the Bilusaludo. The United Earth spent the four years it took to complete Mechagodzilla keeping Godzilla at bay while slowly leading him across Eurasia and toward Japan. In 2046, Godzilla finally reached the facility and prepared to eliminate the threat, with the United Earth mustering all of its forces for a final confrontation. However, Mechagodzilla failed to activate for unknown reasons, and was destroyed along with the entire facility once Godzilla defeated the United Earth. The United Earth abandoned all further plans to continue to battle Godzilla and sent 15,000 selected refugees in search of new habitable planets, leaving the Earth to Godzilla. Unbeknownst to the Bilusaludo, Mechagodzilla's disembodied head survived the battle, and its artificial intelligence remained active with the sole stated directive to destroy Godzilla.

United Earth troops discover the remains of Mechagodzilla within Mechagodzilla City in GODZILLA: City on the Edge of Battle

Over the next roughly 20,000 years, Mechagodzilla's Nanometal spread across the surrounding area, gradually constructing a replica of its development facility. A group of refugees from the ship Aratrum returned to Earth after finding its destination uninhabitable, with 20,000 years having passed due to time dilation. After their forces were decimated by the much larger and stronger Godzilla, the survivors discovered the Nanometal fortress created by Mechagodzilla, which Bilusaludo technical officer Mulu-elu Galu-gu dubbed "Mechagodzilla City." The United Earth activated Mechagodzilla City and began modifying it into a massive elaborate trap for Godzilla. Using modified Powered Suits called Vultures, Captain Haruo Sakaki, Sergeant Yuko Tani, and Major Rilu-elu Belu-be lured Godzilla toward Mechagodzilla City, where he became trapped in a pit flooded with Nanometal which hardened around him. EMP Harpoons mounted on the City's structures were fired into Godzilla's back after his dorsal fins were destroyed by railguns, overloading him with electromagnetic energy. When Godzilla unexpectedly began converting the excess energy into intense heat instead of exploding, the Vultures began assimilating the pilots with Nanometal, rendering them able to withstand the heat long enough to ram into Godzilla's back and trigger him to explode. Haruo's body rejected the fusion due to his having been healed earlier by the scales secreted by the Houtua. Exif archbishop Metphies told Haruo over a communicator that once Godzilla was destroyed, Mechagodzilla City would overtake the entire planet and assimilate all of its life with Nanometal. When Galu-gu refused to stop the Nanometal's encroachment, Haruo reluctantly destroyed him along with Mechagodzilla City's control room with the Vulture's cannon, deactivating all of its Nanometal. After a few moments, Godzilla finally recovered and swiftly incinerated the entirety of Mechagodzilla City with his atomic breath.

Mechagodzilla battles the Iron Giant in Ready Player One

As Wade Watts and his allies closed in on Anorak's Castle within the virtual reality game OASIS, Innovative Online Industries CEO Nolan Sorrento summoned Mechagodzilla to battle them. Mechagodzilla charged into the fray, obliterating foes with its finger missiles and mouth-mounted flamethrower. It was soon confronted by the Iron Giant and RX-78-2 Gundam, piloted by Wade's allies Helen Harris and Daito. The Gundam held its own against Mechagodzilla but was eventually destroyed; however, Samantha shot out Mechagodzilla's eye with her pulse rifle as the machine held her in the palm of its hand. She then threw a Madball grenade into the hole, which detonated inside the cockpit and killed Sorrento's avatar, destroying Mechagodzilla in the process.


Mechagodzilla was the last "Big Five" monster to be introduced in Legendary Pictures and Warner Bros.'s Monsterverse film series, serving as the antagonist of its fourth entry, Godzilla vs. Kong.

Godzilla vs. Kong

Main article: Mechagodzilla (Monsterverse).

Following Godzilla's victory over King Ghidorah in Boston in 2019, eco-terrorist Alan Jonah and his mercenaries came into possession of one of Ghidorah's heads, which had been severed in an earlier battle with Godzilla near Isla de Mara, Mexico. Jonah eventually sold the head's skull to Apex Cybernetics CEO Walter Simmons, who transformed it into a control system for his company's ultimate anti-Titan weapon: Mechagodzilla. By 2024, Mechagodzilla was nearly complete, with its development causing Godzilla to attack Apex's facility in Pensacola, Florida. Using the opportunity to frame Godzilla as an enemy to mankind, Simmons convinced Monarch to join Apex in an expedition to the Hollow Earth in search of an energy source which could power his weapon. As the expedition, escorted by Kong, made its way to the energy source's location in a massive temple, Mechagodzilla was activated for a test run in which it cleaved a gigantic Skullcrawler in half with its proton scream. Madison Russell and her allies Josh Valentine and Bernie Hayes infiltrated Apex's Hong Kong headquarters and witnessed Mechagodzilla's test run, but were taken prisoner by Simmons. After the energy source was found and copied, Simmons ignored Mechagodzilla pilot Ren Serizawa's warnings and immediately used it to power Mechagodzilla, causing Ghidorah's lingering consciousness to merge with the mecha's A.I. and override control from Serizawa, killing him with an electrical surge in the process. The rogue Mechagodzilla killed Simmons next and tore its way into Hong Kong, where Godzilla had just defeated Kong in an intense battle. Mechagodzilla immediately turned its rage toward Godzilla, bombarding him with missiles before brutalizing him in hand-to-hand combat. Monarch operative Nathan Lind revived Kong by detonating a HEAV on his chest, after which Kong's human companion Jia convinced him to come to Godzilla's aid. Just before Mechagodzilla could finish Godzilla, Kong leapt into the battle and saved his former foe. The two Titans joined forces and overcame Mechagodzilla, with Godzilla using his atomic breath to charge Kong's battle axe and allowing him to slice Mechagodzilla apart.


The abilities of each incarnation of Mechagodzilla vary greatly. This section will attempt to document some of the common abilities of multiple incarnations. To see more specific information on Mechagodzilla's abilities, please refer to each incarnation's individual page.

Beam weapons

Each version of Mechagodzilla possesses some form of beam-based weapon, often designed to mimic or counter Godzilla's atomic breath. In Godzilla vs. Mechagodzilla, Mechagodzilla fires a yellow beam from its mouth while in its Fake Godzilla disguise which is powerful enough to destroy large swaths of a port area in Tokyo. After shedding this disguise, Mechagodzilla's primary beam weapon is the rainbow-colored Space Beam (スペースビーム,   Supēsu Bīmu) it fires from its eyes. The Space Beam is powerful enough to destroy most objects instantaneously and is capable of injuring Godzilla. It is also roughly equal in power to Godzilla's atomic breath, colliding with it in midair for several seconds before exploding. The rebuilt Mechagodzilla 2 in Terror of Mechagodzilla retains the Space Beam but now has a Laser Firing Apparatus (レーザー発射装置,   Rēzā Hassha Sōchi) on its "back-up" Head Controller (ヘッドコントローラー,   Heddo Contorōrā),[12] which it utilized after its head was removed by Godzilla.[13] In addition to these beams, Mechagodzilla could fire a powerful electromagnetic beam called the Cross Attack Beam (クロスアタックビーム,   Kurosu Atakku Bīmu) from a shutter on its chest.

In Godzilla vs. Mechagodzilla II, Mechagodzilla's primary beam weapon is the Mega Buster, a rainbow-colored beam fired from its mouth. The Mega Buster is equal in power to Godzilla's standard atomic breath, but is prone to overheating and thus can only be fired continuously for a short period of time. Mechagodzilla also possesses twin yellow Laser Cannons (レーザーキャノン,   Rēzā Kyanon) which it fires from its eyes. The Heisei Mechagodzilla's most powerful beam weapon is the Plasma Grenade (プラズマ・グレネイド,   Purazuma Gureneido), a concentrated beam of superheated plasma fired from a port on its stomach, powered by beam attacks from other monsters which it absorbs through its synthetic diamond-coated armor. After merging with the Garuda to become Super Mechagodzilla, the machine gains access to one more beam weapon: the powerful long-range High Power Maser Beam Cannons (ハイパワーメーサービームキャノン,   Hai Pawā Mēsā Bīmu Kyanon).

Kiryu fires his Type-99 Double Maser Cannon in Godzilla Against Mechagodzilla

In Godzilla Against Mechagodzilla and Godzilla: Tokyo SOS, Kiryu's primary beam weapon is the Type-99 Double Maser Cannon (99式2連装メーサー砲,   99-Shiki 2 Rensō Mēsā-hō) or Twin Maser Cannon (ツインメーサー砲,   Tsuin Mēsā-hō) mounted inside his mouth. In Tokyo SOS, his chest-mounted Absolute Zero Cannon is replaced by the Type-4 Triple Hyper Maser Cannon (4式3連装ハイパーメーサー砲,   4-Shiki 3 Rensō Haipā Mēsā-hō).

In the GODZILLA anime trilogy, Bilusaludo engineers designed Mechagodzilla with a Convergent Neutron Cannon (収束中性子砲,   Shūsoku Chūseishi-hō), a charged particle gun composed of a special gun barrel and a generator located inside its head. Mechagodzilla's head would have deformed when firing the weapon, which possessed an effective range of over five kilometers and would allow Mechagodzilla to approach Godzilla safely.

Mechagodzilla fires a blue flame from its mouth in Ready Player One
Mechagodzilla's Proton Scream overpowers Godzilla's atomic breath in Godzilla vs. Kong

In Ready Player One, Mechagodzilla fires a blue flamethrower-like weapon from its mouth, largely resembling Godzilla's atomic breath from the 2014 Hollywood film. In Godzilla vs. Kong, Mechagodzilla's favored weapon is the red-colored A-74 Proton Scream (A-74プロトンスクリーム) which it fires from its mouth. The Proton Scream is incredibly powerful, as at merely 40% power it was sufficient to completely cleave a giant Skullcrawler in half. At full power, it can tear through buildings instantly and was able to overpower Godzilla's atomic breath in a beam clash and left a searing burn on his chest.

Missiles and rockets

Mechagodzilla 2 uses its revolving Finger Missiles to destroy a street in Tokyo in Terror of Mechagodzilla

All incarnations of Mechagodzilla, with the sole exception of the version from the GODZILLA anime trilogy, possess missiles or rockets in their arsenal. The Showa Mechagodzilla in particular has a vast arsenal of missiles it can fire from several locations on its body. Primarily, it fires Finger Missiles (フィンガーミサイル,   Fingā Misairu) that possess incredible destructive power and are continuously reloaded after each shot. In Terror of Mechagodzilla, Mechagodzilla 2 continuously rotates its hands when firing its Finger Missiles, granting them five times the destructive power of the original model's missiles.[14] The Showa Mechagodzilla also is equipped with time-delayed missiles in its knees, referred to as Homyu Shot (ホーミューショット,   Hōmyū Shotto), and drilling missiles in its toes called High Pressure Homing missiles (ハイプレッシャーホーミング,   Hai Puresshā Hōmingu). It has missiles mounted on the inside of its mouth, which it typically only fires in conjunction with all of its other armaments at the same time. The Showa Mechagodzilla has an apparatus mounted in its neck called the Trace Device (トレイス装置,   Toreisu Sōchi), which allows for the firing of a large quantity of small missiles, though it never uses it onscreen.

Super Mechagodzilla stuns Godzilla with its Paralyzer Missiles in Godzilla vs. Mechagodzilla II

In Godzilla vs. Mechagodzilla II, Mechagodzilla fires Paralyzer Missiles (パラライズ・ミサイル,   Pararaizu Misairu) from cells on its shoulders. It can load 60 Paralyzer Missiles at a single time. It used these missiles in its first battle with Godzilla to temporarily stun him before electrocuting him with its Shock Anchors. Mechagodzilla can also fire Tranquilizer Missiles (トランキライザー・ミサイル,   Torankiraizā Misairu) laced with anesthetics and tranquilizers from ports on both of its hips. Super Mechagodzilla used these missiles to stun Godzilla before targeting and attacking his secondary brain with the G-Crusher.

Kiryu launches Multiple Interlocking Rockets in Godzilla Against Mechagodzilla

Kiryu can fire large Type-87 680 mm Multiple Interlocking Rockets (87式多連装ロケット弾,   87-Shiki Tarensō Roketto-dan) or MRL 2 Mk. IV rockets from the front of the shoulder-mounted cannons on his Back Unit. In Godzilla: Tokyo SOS, these are replaced with improved Type-04 MRL 2 Mk. IV rockets. Kiryu's Back Unit is also equipped with small ballistic homing rockets which are fired from its sides. In Godzilla Against Mechagodzilla, these are Type-95 470 mm Multipurpose Guided Missiles (95式470mm多目的誘導弾,   95-Shiki 470 Emuemu Tamokuteki Yūdō-dan), while in Godzilla: Tokyo SOS they are replaced by Type-98 320 mm Multipurpose Guided Missiles (98式320ミリ多目的誘導弾,   98-Shiki 320-Miri Tamokuteki Yūdō-dan). These rockets are capable of striking a target from long range or while Kiryu is in close-quarters combat.

Godzilla is struck by a barrage of Mechagodzilla's missiles in Godzilla vs. Kong

In Ready Player One, Mechagodzilla uses finger-mounted missiles much like the Showa incarnation. In Godzilla vs. Kong, Mechagodzilla has two sixteen-cell missile launchers which rise from behind its shoulder pads. These missiles operate like cluster munitions, with each missile splitting apart into numerous smaller missiles before impact. It is also equipped with multiple hidden missile launchers; it deployed a concealed four-cell missile launcher in its shoulder to force Godzilla to release his grip on its arm, and has three more concealed four-cell missile launchers in its chest which it never utilizes onscreen.


Mechagodzilla blasts Godzilla with its Space Beams while flying through the air in Godzilla vs. Mechagodzilla

Most versions of Mechagodzilla possess some flight or propulsion capability, though the extent of this ability varies. The Showa incarnation of Mechagodzilla possesses propulsion jets in its feet called Jet Fire (ジェットファイヤー,   Jetto Faiyā), which enable flight at Mach 5.[15] Mechagodzilla can still use its weaponry when in midair, specifically its Space Beams, by aligning its head to face forward.

Super Mechagodzilla performs its Hover Attack against Godzilla in Godzilla vs. Mechagodzilla II

The Heisei Mechagodzilla can fly using built-in jets on its back at a speed of Mach 1. It typically uses this capability to cover large distances in order to confront its foes, but it can also perform a maneuver called the Hover Attack (ホバーアタック,   Hobā Atakku) in which it uses its boosters to suspend itself off the ground and fire its weapons while circling its enemy. This maneuver allows Mechagodzilla to compensate for its lack of mobility on the ground and avoid close-range combat. After combining with the Garuda to become Super Mechagodzilla, its flight capabilities are enhanced thanks to the other craft's boosters, making its Hover Attack more effective.

Kiryu is equipped with rocket boosters that can move and allow him to change direction quickly. While these boosters allow for limited flight, doing so depletes Kiryu's energy quickly and he uses this sparingly. He typically is transported through the air by a squadron of AC-3 White Herons which carry him using cables. When Kiryu does use his rocket boosters, he can use his momentum to ram opponents.

Mechagodzilla knocks Godzilla down with a plasma punch combined with its jet boosters in Godzilla vs. Kong

In Godzilla vs. Kong, Mechagodzilla has a set of six rocket boosters that fire out of openable ports by its dorsal fins. These boosters make Mechagodzilla more agile in close-quarters combat, helping it gain the upper hand against Godzilla. Designer Jared Krichevsky confirmed that there are also jets inside of Mechagodzilla's tail.[16]

Armor and defensive capabilities

Godzilla's atomic breath is repelled by Mechagodzilla's Defense Neo Barrier in Godzilla vs. Mechagodzilla

In order to withstand Godzilla's powerful attacks in combat, all versions of Mechagodzilla are designed with incredibly durable armor and other defensive capabilities. The Showa Mechagodzilla is built from highly durable Space Titanium, an extraterrestrial alloy possessing ten times the strength of steel. It can also deploy a shield called the Defense Neo Barrier (ディフェンスネオバリヤー,   Difensu Neo Bariyā) by rotating its head at high speed while firing beams from its eyes. This barrier deflected Godzilla's atomic breath and knocked him down when he tried to physically penetrate it.

Mechagodzilla's Diamond Coating harmlessly absorbs Godzilla's atomic breath in Godzilla vs. Mechagodzilla II

The Heisei Mechagodzilla is covered in an armor plating made from a synthetic alloy called NT-1, which is covered in an artificial Diamond Coating (ダイヤモンド・コーティング,   Daiyamondo Kōtingu). This diamond coating is designed to render Godzilla's atomic breath completely harmless, as well as enable the mech to absorb its plasma energy in order to power its Plasma Grenade. While the Diamond Coating has a limit and begins to melt after being exposed to Godzilla's Fire Rodan-empowered nuclear pulse, its armor plating was still durable enough to withstand multiple hits from Godzilla's Uranium Atomic Heat Ray before it was destroyed.

Mechagodzilla City's Nanometal Buffer Lair deflects Godzilla Earth's atomic breath in GODZILLA: City on the Edge of Battle

In the GODZILLA anime trilogy, Mechagodzilla is composed of Nanometal, an autonomous living metal created by the Bilusaludo. Nanometal is able to deform and reform or become fluid and harden instantaneously, allowing Mechagodzilla to regenerate and adapt to any damage sustained in battle. Though it never had an opportunity to demonstrate these capabilities against Godzilla, enough of its Nanometal survived its body's destruction by Godzilla in 2046 to remain active over the ensuing 20,000 years. Its Nanometal gradually evolved and spread across the nearby area, all while following its directive to destroy Godzilla, constructing a weaponized replica of its development facility. Mechagodzilla could also spread Nanometal particles over a radius of 300 meters to defend itself from energy-based attacks and large projectiles, a feature designated the Nanometal Particle Diffusing-Type Thermal Energy Buffer Layer (ナノメタル粒子散布型熱エネルギー緩衝層,   Nanometaru Ryūshi Sanpu-gata-netsu Enerugī Kanshō-sō). Mechagodzilla City was able to utilize this ability to defend itself from Godzilla Earth's atomic breath.

In Godzilla vs. Kong, Mechagodzilla's endoskeleton is composed of titanium and its body frame from T-1 Nanometal Skeleton Housing. This renders it highly resistant to damage, as it shows virtually no strain in its initial battle with Godzilla. Once Kong joined the battle, Mechagodzilla still demonstrated little to no damage from the combined attacks of both Titans, even withstanding numerous strikes from Kong's uncharged battle axe. Only once Kong's axe is charged by Godzilla's atomic breath does it become capable of damaging Mechagodzilla.

Artificial intelligence

Most versions of Mechagodzilla, despite being robotic, possess some degree of autonomy in battle. In Godzilla vs. Mechagodzilla, Mechagodzilla automatically carries out commands relayed verbally by the Black Hole Planet 3 Alien commander Kuronuma, and is able to make its own decisions in combat. It strategically attempts to keep both Godzilla and King Caesar at bay when they join forces against it. In Terror of Mechagodzilla, Mechagodzilla 2 is controlled by Katsura Mafune's organic brain tissue, which according to her father Dr. Shinzo Mafune renders it superior to the original model. So long as Katsura lives, Mechagodzilla is able to continue operating, even if she is not consciously controlling it.

In Godzilla vs. Mechagodzilla II, Mechagodzilla is controlled almost entirely by a team of G-Force pilots, though it still utilizes an artificial intelligence called REIKO. In Godzilla Against Mechagodzilla and Tokyo SOS, Kiryu is controlled using DNA computers which allow him to carry out autonomous subconscious motor function while responding to orders from his operators aboard the AC-3 White Herons. However, the presence of the first Godzilla's skeleton within Kiryu has on two occasions allowed the monster's dormant consciousness to completely override all control of the cyborg from his pilots.

In the GODZILLA anime trilogy, Mechagodzilla is equipped with a highly sophisticated Bilusaludo quantum computer and A.I. called Zalu-zi Type One Modified, which is itself supplied with a Gematron calculation algorithm and Godzilla combat data supplied by the A.I. Deinde. The combination of all of these algorithms and A.I. allows Mechagodzilla to form tactics in battle. After Mechagodzilla and its development facility were destroyed, its artificial intelligence block survived within its intact disembodied head and continued operating at half capacity for 20,000 years, carrying out its directive to "destroy Godzilla" by constructing Mechagodzilla City. Mulu-elu Galu-gu later remarks that the combination of Mechagodzilla's A.I. and the consciousness of the Bilusaludo who fused with its Nanometal is sufficient to allow Mechagodzilla City to make its own independent decisions.

In Godzilla vs. Kong, Mechagodzilla runs on an operating system called "Kuronuma Psionic v1.3," and is designed to be piloted mentally by Ren Serizawa through a neural interface built into one of King Ghidorah's skulls. However, the influx of energy from the Hollow Earth causes Ghidorah's dormant consciousness to merge with Mechagodzilla's A.I. and form a new malevolent consciousness that severs its connection to Serizawa before killing its creators and going berserk. Mechagodzilla is also stated to possess built-in learning algorithms.


Despite their incredible power, each version of Mechagodzilla possesses at least one critical weakness.

Godzilla destroys Mechagodzilla by twisting its head off in Godzilla vs. Mechagodzilla

In Godzilla vs. Mechagodzilla, Mechagodzilla is controlled primarily through receivers on the sides of its head called Cybanecks, which receive commands from Kuronuma and allow it to navigate. When the Cybanecks are damaged following an explosion caused by its Space Beams colliding with Godzilla's atomic breath, Mechagodzilla is rendered almost completely inoperable and Kuronuma is forced to immediately recall it to the Black Hole Planet 3 Aliens' base for repairs. Godzilla forcibly tears off Mechagodzilla's head in their next battle, which causes severe damage to its upper body and renders it inoperable. In Terror of Mechagodzilla, the aliens circumvent the first model's weaknesses by equipping Mechagodzilla 2 with a secondary head controller underneath its head and installing its control device within the cyborg woman Katsura Mafune. However, once Katsura commits suicide and, by so doing, destroys the control device, Mechagodzilla can no longer move or attack and is easily destroyed by Godzilla.

Super Mechagodzilla's diamond coating begins to melt after exposure to Godzilla's Fire Rodan-empowered nuclear pulse in Godzilla vs. Mechagodzilla II

The Heisei Mechagodzilla is designed for ranged combat, with its diamond-coated armor deflecting Godzilla's atomic breath and its numerous weapons keeping him at bay. Once Fire Rodan and later Godzilla close the distance in their battles against Mechagodzilla at Makuhari Bay, Mechagodzilla can do little to defend itself and suffers severe damage; with Fire Rodan disabling its right eye with his beak and Godzilla lifting and throwing Mechagodzilla. Mechagodzilla's Mega Buster is prone to overheating and must be fired for short periods of time, resulting in the mech stalling and becoming immobile after a sustained beam lock with Godzilla's atomic breath. Mechagodzilla's diamond coating, while more than capable of absorbing Godzilla's standard atomic breath and Fire Rodan's uranium heat ray, cannot withstand the intense heat emitted by Godzilla's nuclear pulse after he absorbs Fire Rodan's life force and begins to melt. This renders Mechagodzilla vulnerable to Godzilla's uranium spiral heat ray, which obliterates it in a few hits.

Aside from his susceptibility to being possessed by the original Godzilla's spirit, Kiryu consumes energy quickly and can only run for approximately two hours at a time, with his flight abilities and use of the Absolute Zero Cannon depleting his energy reserves even more quickly. The transmitter which allows Kiryu to receive orders from his pilots can also be damaged by Godzilla's atomic breath, knocking him out of commission until he is either piloted manually or the transmitter is repaired.

Kong slices off Mechagodzilla's arm with his charged battle axe in Godzilla vs. Kong

In Ready Player One, Mechagodzilla is destroyed when its eye is shot out and a Madball grenade is thrown into its cockpit, killing Nolan Sorrento's avatar and triggering a chain reaction that causes the entire robot to explode.

In Godzilla vs. Kong, Mechagodzilla is temporarily stalled when Josh Valentine pours a flask of alcohol onto a control board, allowing Godzilla to power Kong's battle axe with his atomic breath. While Mechagodzilla was otherwise indestructible, Kong's charged axe was able to slice through its body and allowed Kong to cut off several appendages before tearing off its head.

Video games

Godzilla: Monster of Monsters!

The Showa Mechagodzilla appears in Godzilla: Monster of Monsters! for the Nintendo Entertainment System, in which it is one of the strongest monsters fought by Godzilla and Mothra, possessing the most health of any monster, barring King Ghidorah. It attacks with punches, kicks, and a laser from its eyes. Its attacks are strong, so it can prove difficult for Godzilla, but Mothra can beat it easily by flying right under its chin, where none of its attacks can hit her.

Super Godzilla

Mechagodzilla appears as the second boss in the the U.S. version of Super Godzilla for the Super Nintendo Entertainment System. Though the Japanese version featured the Heisei Mechagodzilla, the localization team of game designers for Super Godzilla changed the character to the more-familiar Showa Mechagodzilla for the U.S. version, since Godzilla vs. Mechagodzilla II had not been released in the U.S. yet. Despite the change in appearance, the boss battle is overall the same fight in both versions, with some minor differences. First, as a reference to the film it appeared in, the Showa Mechagodzilla first appears disguised as Godzilla, though the disguise disappears after one hit. Other than that, the only gameplay difference is that the Showa Mechagodzilla has its finger missiles in place of the Heisei Mechagodzilla's Mega Buster, which do less damage.

Godzilla (TurboDuo)

There are four different incarnations of Mechagodzilla featured in the game Godzilla for the TurboDuo. Mechagodzilla 1974, referred to as "MGI," appears as an opponent on one of the game's Single Player Mode stages, as does Mechagodzilla 1993. Both Mechagodzilla II and Super Mechagodzilla appear as optional final bosses in the game. All four Mechagodzillas are playable in Versus Mode.

Godzilla: Great Monster Battle

Both the Showa and Heisei Mechagodzillas reappear in the sequel to Godzilla, Godzilla: Great Monster Battle, on the Super Famicom. The Showa Mechagodzilla is playable in Single Player Mode, while the Heisei Mechagodzilla acts as one of the potential final bosses. Heisei Mechagodzilla and Super Mechagodzilla are playable only in Multiplayer Mode.

Godzilla: Destroy All Monsters Melee

The U.S. GameCube version of Godzilla: Destroy All Monsters Melee features a single Mechagodzilla, which is a sort of hybrid between the Showa and Heisei Mechagodzillas, bearing the design of the Heisei version but the abilities and story role of the Showa version. For the Japanese release of the game, this Mechagodzilla was replaced by Kiryu from the then-recent film Godzilla Against Mechagodzilla. When the game was released for the Xbox in the U.S., both the Heisei Mechagodzilla and Kiryu were included in the game, under the names "Mechagodzilla 2" and "Mechagodzilla 3," respectively.

Godzilla: Domination!

Mechagodzilla is one of the playable monsters in the game Godzilla: Domination! for the Game Boy Advance. In the U.S. version of the game, Mechagodzilla bears the appearance of the Heisei incarnation, while in the Japanese version it is patterned after Kiryu from Godzilla: Tokyo SOS However, the differences are only cosmetic, and Mechagodzilla plays identically in both versions. Mechagodzilla has the ability to unleash a flame from its hand in a slow attack with good reach. It also can perform a hydraulic kick, where it unleashes a flame from the jets on its feet for a slow attack with excellent reach. It can also do a claw launch, in which it fires off its fist, which will fly forward and then turn around and return to Mechagodzilla. Its other abilities include the power to fire an electric bolt from its navel area (similar to the Plasma Grenade), the ability to launch six heat-seeking missiles from compartments located on its back and the ability to create a cooling steam from its chest plates which will slightly heal Mechagodzilla and injure nearby monsters.

Godzilla: Save the Earth

Both Mechagodzilla 2 and Mechagodzilla 3 return in Godzilla: Save the Earth, the sequel to Godzilla: Destroy All Monsters Melee, for the PlayStation 2 and Xbox, with their movesets largely unchanged.

Godzilla: Unleashed

The Wii version of Godzilla: Unleashed features the Showa, Heisei, and Millennium Mechagodzillas as playable monsters. The Showa version, simply referred to as Mechagodzilla, is a member of the Aliens faction, while the Heisei version, known as Mechagodzilla 2, and Kiryu are both part of the Global Defense Force. Mechagodzilla can spew a flamethrower from its nose and create a force field that reflects all projectiles thrown at it. Mechagodzilla 2 is partially a clone of Mechagodzilla, though trading one cell of defense for one cell of speed. The only major differences between Mechagodzilla 1 and 2 is that the latter can hover, fire its Plasma Cannon and use its jets to push away opponents like King Ghidorah and Mecha-King Ghidorah use their wings aside from flying. In this game, Mechagodzilla and Mechagodzilla 2 are the only monsters who can knock out a health cell with a beam attack. Kiryu is a starter character in this game, and is a considerably more agile and melee-oriented combatant than the other two Mechagodzillas.


Height: 98 meters
Weight: 73,000 tons "Mechagodzilla was the first attempt by the Vortaak to subjugate the human population of the Earth. Plated in space titanium, Mechagodzilla proved to be too well armored for any of Earth's monsters to defeat single-handedly. Unfortunately for the Vortaak, the Earth Defenders are more than willing to work as a team when necessary, and through their combined effort, Mechagodzilla was destroyed. In their latest invasion attempt, the Vortaak have rebuilt Mechagodzilla to fight alongside them once more. With allies of his own on hand, Earth's monsters will need to make full use of their speed advantage when battling this indomitable nemesis."

Mechagodzilla 2

"Mechagodzilla 2 was directly inspired by the Vortaak's Mechagodzilla. GDF weapons designers saw that a heavily-armored combatant who blended ranged firepower and heavy melee attacks at the cost of some mobility could be a very effective way to hold back monster attacks on major cities. Although they could not duplicate the space titanium alloy used in the original, the GDF was able to create an armor composite which resisted bite and claw attacks to a miraculous degree-as well as absorbing a significant portion of the heat and radiation weapon attacks used by many of Earth's monsters. This focus on defense before offense proved to be a powerful mixture, and Mechagodzilla 2 remains a staple of the GDF's anti-monster force."


Height: 100 meters
Weight: 66,600 tons

"Kiryu is a cyborg monster generated by the Global Defense Force to protect human cities from monster threats. Kiryu is genetically identical to Godzilla, but has been augmented with armor plating, enhanced reflexes, and limited flight capabilities. These enhancements have eliminated his natural ability to create atomic fire, so he has been outfitted with homing rockets, an electrical cannon, and the fearsome Absolute Zero cannon-which can immobilize any monster in a single hit. Kiryu is the GDF's most successful defender yet, and is their first and best option for defending humanity."

Godzilla (PlayStation 3 / PlayStation 4)

Mechagodzilla 2, Super Mechagodzilla, and Kiryu all appear in Godzilla for the PlayStation 3, while the PlayStation 4 version also adds the original 1974 Mechagodzilla. While the Mechagodzillas appear only as enemies in God of Destruction and King of Kaiju Mode in the PS3 version, they are all playable in the PS4 version. Mechagodzilla and Mechagodzilla 2 are playable in the Invade variant of God of Destruction Mode, while Super Mechagodzilla and Kiryu are playable in the Defense variant. For complete movesets of the Mechagodzillas in this game, please refer to the incarnations' individual pages.

City Shrouded in Shadow

In the survival RPG City Shrouded in Shadow developed by Granzella and Bandai Namco for the PlayStation 4, Kiryu is under the control of the JXSDF and sent to battle Godzilla. However, Godzilla's roar causes Kiryu to go berserk, turn against his masters and attack the player, a reference to his similar behavior in Godzilla Against Mechagodzilla.


Godzilla on Monster Island

When human surveillance of Monster Island discovered that a giant cocoon had washed up there, researchers feared that the monsters living there would destroy it. Mechagodzilla was deployed to recover the specimen and quickly overpowered Anguirus, who was guarding it. Rodan, who arrived to help Anguirus and was also no match for the mecha, went to get Godzilla, who quickly made it ashore and easily defeated Mechagodzilla. After the battle, the cocoon hatched into Mothra.

Ready Player One

Main article: Mechagodzilla (Ready Player One).

Mechagodzilla was a powerful magical artifact in a virtual-reality game called the OASIS, piloted by the diabolical leader of Innovative Online Industries (IOI), Nolan Sorrento. The machine seemed invincible as the final battle between OASIS players and IOI commenced, shrugging off attacks from Leopardon, an RX-78-2 Gundam, and Raideen. Minerva X managed to damage one of its shoulder cannons, but the pilots realized they needed to retreat. Raideen's pilot Akihide, seeking to avenge the death of his friend Toshiro Yoshiaki, sacrificed himself to buy the others time. Mechagodzilla's lightning blast destroyed Leopardon as well, and its pilot, Wade Watts, decided Sorrento needed to be humbled. Using the Beta Capsule Akihude had given him, he transformed into Ultraman. He unleashed a devastating flurry of attacks: a Specium Ray to knock Mechagodzilla over, a flying kick to its spine, and an Ultra-Slice to cut it in half. Sorrento ejected in Mechagodzilla's head, but Wade shot him down with another Specium Ray.

Godzilla vs. Kong: Sometimes Friends Fight (But They Always Make Up)

Mechagodzilla meets up with Godzilla and Kong near a playground.

Godzilla x Kong: The New Empire - The Official Movie Novelization

Monarch is noted to have collected Mechagodzilla's remains after Kong destroyed it and used the advanced technology within to aid in the construction of the B.E.A.S.T. Glove, a weapon designed for the ape Titan to wield.[18]


Godzilla, King of the Monsters

A third rebuild of the Showa Mechagodzilla, constructed around an "electronic brain" located in the depths of the excavations for the Tokyo Bay Aqua-Line, was created by the mad scientist Dr. Mad Oniyama, who also rebuilt Mechani-Kong. He also crafted a false skin and placed it on Mechagodzilla to create a new Fake Godzilla, which began attacking the city of Tokyo. Yosuke Kaneko confronted the machine with his ASTOL-MB93, shooting off a piece of the robot's fake skin. This only provoked Mechagodzilla into revealing itself, firing its finger missiles directly through its hands. Yosuke kept firing on the machine with the ASTOL-MB93's masers, eventually burning off the rest of Mechagodzilla's disguise. Mechagodzilla III, as it was now called, and the newly-summoned Mechani-Kong II tag-teamed Godzilla, holding him steady with a vice-like grip. Oniyama's Mechagodzilla III then brutally skewered Godzilla through the chest using its arms after being given the command to "shred Godzilla".

Godzilla managed to break free when Yosuke stunned Mechani-Kong II with his ASTOL-MB93's masers, and then grabbed Mechani-Kong by the arm, throwing it over his shoulder to the ground, where it became deactivated. After Godzilla destroyed Mechani-Kong with a shot of his atomic breath, Mechagodzilla III faced him in battle, and put up more of a fight, forcing the King of the Monsters back with its Space Beams and Finger Missiles. Yosuke intervened again, firing on Mechagodzilla's Super Radar and leaving the robot unable to defend against Godzilla's atomic breath, which blew off a substantial amount of its outer casing around its head and upper body, blasting it into Tokyo Bay. With its electronic brain exposed and short-circuiting, Mechagodzilla feebly uttered Godzilla's name before being hit by another shot of atomic breath, causing the robot to finally explode.

A second, Mechagodzilla-esque robot called Machine G that was constructed by the heroic Team G was activated after Godzilla was defeated and incapacitated by Oniyama's final creation, King Godzilla. Though effectively a Mechagodzilla in all but name, it had a significantly different design and set of weapons compared to Mechagodzilla III.

Machine G battled King Godzilla in Godzilla's stead atop the volcano at Oniyama's base of operations, Satan Atoll, and while it was ultimately unable to stop the chimera monster and was almost destroyed during the fight, it gave Godzilla enough time to recover, come to the rescue, and hurl himself and his clone into the volcano's magma, defeating King Godzilla and Oniyama once and for all.

Godzilla: Legend

Mechagodzilla in Godzilla: Legend

Mechagodzilla was being constructed by a group of Xiliens underneath an unassuming house in the Japanese countryside. It is launched later and fights Godzilla, but it is soon defeated.

Godzilla vs. Mechagodzilla II (Shogakukan)

In this manga adaptation of its debut film by Shogakukan, Mechagodzilla appears as the main antagonist. In this adaptation it is noticeably more brutal and powerful, being able to rip Godzilla's dorsal fins in half with little effort. Mechagodzilla also gains several new abilities, including the ability to fire its arms off on a pair of cables from its shoulders at foes. In the first fight against Godzilla, Mechagodzilla overpowers him, tearing his dorsal plates in half and blasting his eyes out with shots of its Mega Buster Ray. However, Godzilla manages to behead Mechagodzilla, and retreats. It is then explained that Mechagodzilla's brutal abilities are related to a remnant of Mecha-King Ghidorah's programming being present in the mecha's computers. In the subsequent battle, Mechagodzilla uses the G-Crusher on Godzilla, but this fails after Fire Rodan revives him. The kaiju and the machine resume fighting, but Mechagodzilla is no match for its enhanced opponent, and it is soon defeated.

Godzilla vs. SpaceGodzilla

In this manga adaptation of the film, also by Shogakukan, Mechagodzilla is rebuilt by G-Force and deployed after the manga's main protagonist, Akira Yuki, steals MOGUERA from the U.N.G.C.C.. Mechagodzilla enters battle against its successor, but it is quickly destroyed.

Godzilla: Kingdom of Monsters

Only a month after Godzilla first emerged and attacked Japan, U.S. President Ogden announced that his think tank of military leaders, economists, and scientists had developed a plan to kill Godzilla - the Mechagodzilla Project, a joint U.S.-Japanese operation which would oversee the construction of a giant mech being built in Detroit, Michigan. Mere weeks later, the completed mech was unveiled to the public before being dispatched to intercept Godzilla, who had by then made it to South Dakota. Upon arrival, Mechagodzilla unleashed a volley of missiles on its target, only to be knocked to the ground by Godzilla's atomic breath. The two foes exchanged further beam fire before Mechagodzilla switched tactics and flew directly into Godzilla to initiate a physical battle, though Godzilla gained the upper hand once again. During the struggle, Godzilla managed to strike Mechagodzilla in the back of the head, which had not been insulated against Godzilla's atomic breath like the anterior was, causing the mech to malfunction and begin acting on its own. The berserk Mechagodzilla flew to Atlanta, Georgia and decimated the city with its various weapons while the government tried and failed to regain control over it.

Some time later, Steven Woods and Allie encountered the still out-of-control mech ravaging the countryside minutes before it finally shut down. The next day, Steven and Allie entered Mechagodzilla's cockpit and reactivated the mech, where they attempted to learn its controls. Shortly thereafter, Anguirus appeared before them, at which point Steven resolved to fight back against the monsters wreaking havoc upon the planet. Anguirus leapt at Mechagodzilla, and though Steven was able to block the attack, Anguirus curled into a ball to attack again, this time knocking Mechagodzilla down. As Anguirus began shredding through Mechagodzilla's armor with his claws, Steven discovered Mechagodzilla's paralyzer missiles and fired them point-blank, incapacitating Anguirus. Later, Steven and Allie detected Godzilla near Washington D.C. and plotted to stop the monster. Fresh off of his victory against King Ghidorah, Godzilla was immediately sent flying by Mechagodzilla's Mega Buster ray, though he recovered and fired his atomic breath at Mechagodzilla before charging into the mech. Mechagodzilla narrowly avoided a point-blank blast of Godzilla's atomic breath by grabbing Godzilla's head and pointing it towards the sky, at which point Mechagodzilla beat Godzilla back with a volley of punches, drawing blood. As the battle continued, King Ghidorah recovered and reentered the battle, but opted to ignore Mechagodzilla and go after Godzilla. While Allie theorized that the three-headed dragon could be an ally, Steven did not want to risk taking that chance and fired Mechagodzilla's shock anchors at both monsters, electrocuting them. President Ogden then contacted Steven to tell him about Mechagodzilla's most powerful weapon that had been fully charged by Godzilla's atomic breath - the Plasma Grenade, which promptly subdued both Godzilla and King Ghidorah. Satisfied with defeating Godzilla, Steven switched off Mechagodzilla's manual override under President Ogden's orders, allowing the president’s team to remotely pilot the mech back to Detroit where it was to undergo much-needed repairs.

Godzilla: Gangsters & Goliaths

As a consequence of abducting the Elias from Monster Island and thus causing the natural balance to fall into disarray, detective Makoto Sato unintentionally caused the kaiju of the island to converge on and assault Japan. Remorseful, Makoto sought to right his wrongs by stopping the madman who had kidnapped the Elias from him - Ryota Takahashi. To do this, Makoto infiltrated a G-Force base and, with help from his sons Jiro and Koji Sato, plotted to steal Mechagodzilla. Koji warned him that this Mechagodzilla model was one of the oldest ones that had been retired from active service as a result of failing to stop Godzilla after numerous battles, but Sato assured him that they were not using the mech to stop the kaiju, but to stop Takahashi. However, as the mech was launched into the skies above Tokyo, the trio noticed an evacuation bus that failed to escape the city in time, which was about to be crushed by Godzilla. Makoto and his sons decided to intervene, landing the mech onto Godzilla and firing missiles at him before he could recover, successfully diverting his attention away from the bus. As Godzilla charged up his atomic breath, Koji piloted Mechagodzilla back into the air to dodge the blast, though Godzilla gave chase across the city. The trio then piloted Mechagodzilla directly into Takahashi Tower, where Makoto managed to locate the Elias amidst the rubble, though Takahashi himself escaped in the chaos. Makoto ordered Jiro and Koji to defend the city as best they could using Mechagodzilla while he sought to return the Elias to Mothra. Mechagodzilla proceeded to battle Rodan and the other monsters while Godzilla killed Takahashi and Makoto reunited the Elias with the divine moth, which promptly caused the monsters to stop fighting. Within Mechagodzilla’s cockpit, Jiro and Koji watched as the monsters followed Mothra back to Monster Island, finally putting an end to the turmoil.

Godzilla: Legends

Godzilla: Legends #3

With a black hole gradually dragging their planet to its inevitable destruction, the Simians prepared to launch a full-scale invasion of Earth to ensure their species' survival, amassing a great armada which included two Mechagodzillas. The captive monster Titanosaurus was also intended to aid their Mechagodzilla units in the coming invasion.

Godzilla: Legends #4

A novice G-Force team led by Chief Officer Nashi was dispatched with Mechagodzilla to investigate a kaiju attack that leveled the city of Linfen, China. Unverified reports painted Godzilla as the culprit, though the crew was quick to discover a number of discrepancies that did not match Godzilla's attack patterns, including the speed of the attack, a lack of radiological presence, and unusually high levels of toxicity that left the air thick with smog. While investigating a factory among the ruins with particularly high toxicity readings, the building suddenly exploded, where the true source of the devastation revealed itself - Hedorah. The smog monster latched onto Mechagodzilla, whose lasers were unable to stop Hedorah from smothering the mech and knocking it into a burning building before flying away. Mechagodzilla gave chase, though a member of the team noted that Hedorah's sludge was corroding their armor. After Godzilla appeared and attacked Hedorah, Nashi ordered Mechagodzilla to concentrate all firepower on Godzilla and bombarded him with a barrage of lasers and missiles, deeming Godzilla their top priority. However, Godzilla was unfazed and opted to focus on Hedorah, seemingly regarding the smog monster as the greater threat.

During the fight, Godzilla blasted Hedorah with his atomic ray, which simply went through Hedorah and struck Mechagodzilla. Mechagodzilla then fired its Mega-Buster ray through Hedorah, only to be blasted by Hedorah's own eye beams before the smog monster launched sludge at Mechagodzilla's head. The two opponents continued to exchange beam fire until Godzilla took over again, at which point Mechagodzilla fired the Plasma Grenade at both kaiju at once, though it proved ineffective. With Godzilla being overwhelmed by Hedorah, the Mechagodzilla crew finally realized that Hedorah posed a far greater threat to the world and promptly fired the mech's shock anchors into Hedorah's body and electrocuted it. Angered, Hedorah stopped attacking Godzilla and quickly latched onto Mechagodzilla, with the team reluctantly allowing Godzilla to escape. Taking flight, Mechagodzilla flew Hedorah up into the atmosphere, which began to freeze its body. At risk of running out of fuel, Mechagodzilla fired the Plasma Grenade once more, which shattered Hedorah's frozen body and finally appeared to kill the monster. With their mission complete, Nashi ordered the triumphant crew to return Mechagodzilla to base with what little fuel remained where the mech underwent repairs.


The new Mechagodzilla in Godzilla

Over a month after Godzilla attacked Washington, D.C., billionaire Daniel Malmon unveiled a new version of Mechagodzilla constructed by his own company after the government was unable to repair the previous Mechagodzilla model, boasting that his mechanical creation was created using anatomical data obtained from the real Godzilla and thus was "better than the real thing". As Boxer's Monster Kill Crew were targeting Godzilla in Los Angeles County, California, Malmon piloted the new Mechagodzilla into battle, disrupting their plans. Malmon fired the Absolute Zero Cannon at Godzilla and knocked him down before further firing upon him with Mechagodzilla's railguns. Upon recovering, Godzilla charged into Mechagodzilla, but Malmon took the opportunity to grab his foe, fly up into the air, and drop Godzilla into a building. Shortly thereafter, Godzilla fired his atomic ray at Mechagodzilla, who attempted to counter with its own beam. Godzilla refused to back down, however, and continued to bombard Mechagodzilla with his atomic breath until Mechagodzilla suffered a total system failure from the intense heat and collapsed. In the aftermath, the mech was eventually salvaged and was returned to its hangar, where Malmon stored other aircraft and vehicles he owned.

Some time later, a group of space monsters invaded the Earth, prompting Monster Kill Crew member Harrison to venture to the hangar where he intended on employing Mechagodzilla in the fight against the alien invaders. After hijacking Mechagodzilla, he found that the weapons systems had not yet been repaired, though it was still able to move. Immediately after exiting the hangar, Harrison came face-to-face with the space monster Hedorah, who launched a volley of sludge at the mech. Harrison was able to dodge the attack, only for Hedorah to latch onto Mechagodzilla and smother it anyways. Before Mechagodzilla could be completely overwhelmed, Godzilla suddenly arrived, diverting Hedorah's attention long enough for Harrison to escape. Harrison then flew Mechagodzilla to Monster Island, where the monsters his team had defeated were being contained. Though Boxer had already freed most of the island's monsters with help from Asuka Hikari, Kumonga, being unable to swim or fly, was stranded until Mechagodzilla arrived. Harrison allowed the spider kaiju to hitch a ride on Mechagodzilla's back while Boxer and Asuka joined Harrison in the cockpit. Following a brief stop to refuel, Mechagodzilla journeyed to New York City to confront Monster X, who had already bested Mothra in battle. Once close enough, Kumonga leapt off of Mechagodzilla to attack the alien monster, though Monster X defeated him with ease and threw Kumonga's incapacitated body at Mechagodzilla. Asuka discovered Mechagodzilla's Absolute Zero Cannon was still functional and fired it at Monster X, though the alien invader retaliated with his own powerful Gravity Beams, sending the mech flying into the Hudson River. The cockpit quickly began to flood with water, though the arrival of Godzilla and SpaceGodzilla distracted Monster X from attacking the mech further. Desperate to escape, Boxer ordered Harrison to activate the Absolute Zero Cannon again to further damage Mechagodzilla's destabilized hull, creating a crack in the mech's armor large enough for them to escape through. The blast from the Absolute Zero Cannon also managed to strike SpaceGodzilla, which allowed Godzilla to land a crippling blow on the space monster which sent him into retreat.

Godzilla: The Half-Century War

The original Mechagodzilla (left) and the new Mechagodzilla (right) in Godzilla: The Half-Century War

In 1987, the Anti-Megalosaurus Force unveiled their latest creation in the fight against Godzilla - Mechagodzilla. The mech was dispatched to intercept Godzilla in Bombay, India. Mechagodzilla unleashed a volley of Maser eye beams, the Mega-Buster ray, missiles, and more upon Godzilla, who struggled to get a hit in. As Godzilla and Mechagodzilla continued to battle, Ota Murakami simultaneously happened upon rogue scientist Dr. Deverich, and upon apprehending him, discovered that Deverich had perfected his monster-attracting beacon, the Psionic Transmitter. While attempting to shut the device down, the A.M.F. quickly discovered that the Transmitter had already attracted another monster as it descended upon Godzilla and Mechagodzilla - a new monster from outer space, SpaceGodzilla. A hail of crystals rained down upon Godzilla and Mechagodzilla as SpaceGodzilla arrived, but before Mechagodzilla could engage, SpaceGodzilla fired his powerful Corona Beam at the mech, sending it flying back into several buildings. SpaceGodzilla then impaled the mech with giant crystals he was able to levitate through the air like missiles, crippling Mechagodzilla. With Mechagodzilla out of the fight, SpaceGodzilla proceeded to overwhelm Godzilla and nearly killed him. However, after realizing that a large cluster of crystals behind the space monster was the source of SpaceGodzilla's power, Ota journeyed to the fallen Mechagodzilla, rescued its pilot, and managed to fire all of Mechagodzilla's beams in a single, concentrated blast at the crystal cluster to destroy it. Weakened, SpaceGodzilla was helpless to stop Godzilla from destroying him thanks to Mechagodzilla's help.

Years later, Gigan and King Ghidorah arrived on Earth and began decimating the planet, having been lured there by Deverich's Psionic Transmitter. By 2002, the A.M.F. had completed a brand-new Mechagodzilla model, which was rumored to include pieces of the real Godzilla in its construction. The new Mechagodzilla was brought to a base in Antarctica, where the A.M.F. was planning on utilizing the mech and another new weapon, the Dimension Tide, to stop the monsters once and for all. Godzilla, Gigan, and King Ghidorah were all lured to the site, at which point Ota Murakami hijacked the new Mechagodzilla and piloted it into battle to help the outmatched Godzilla. Entering the fight, Ota fired missiles at Gigan and freed Godzilla from King Ghidorah's grasp before unleashing more missiles and beam attacks onto the three-headed dragon. The two space monsters then concentrated their firepower on Mechagodzilla, overwhelming Ota until Godzilla recovered and engaged King Ghidorah. After Mechagodzilla rescued Godzilla from King Ghidorah's wrath yet again, Godzilla allied himself with his mechanical doppelganger, and the two worked together to critically injure Gigan by severing one of his arms. Shortly thereafter, Ota realized that the Dimension Tide was about to fire and used Mechagodzilla to grab Gigan so he would be within the line of fire with the other kaiju. Together, Godzilla and Mechagodzilla were able to banish the space invaders into the Dimension Tide's miniaturized black hole, though Godzilla attempted to escape once they had done so. Refusing to let him go, Ota flew Mechagodzilla down onto Godzilla and stabbed him in the chest, desperately trying to hold him in place. As the black hole began tearing Mechagodzilla apart, the cockpit was exposed, allowing Godzilla to finally see Ota himself. The black hole then absorbed Mechagodzilla and apparently Godzilla as well, bringing an end to Ota's nearly fifty-year war with Godzilla. However, Godzilla's dorsal fins later broke the surface of the ocean in the aftermath of the battle unseen by anyone, suggesting that Godzilla had somehow escaped.

Godzilla: Rulers of Earth

While speaking with Kenji Ando, a commander in the Chinese military addressed Ando’s involvement with the first Mechagodzilla Project. Steven Woods also kept a toy of the first Mechagodzilla on a desk in his office; his experience with the mech was a major factor in placing him in charge of the new Counter-Kaiju Reaction Forces.

At some point following the invasion of the space monsters, the Counter-Kaiju Reaction Forces acquired, repaired, and upgraded the second Mechagodzilla, which was dispatched to stop Baragon after the monster attacked Paris. Baragon fought fiercely by biting, clawing, and spewing flames at the mech, but Mechagodzilla was able to disorient the small kaiju with a missile attack before knocking him unconscious with an additional punch to the head. Mechagodzilla then transported the monster to the newly-established Monster Islands. Afterwards, Mechagodzilla was stationed on a refueling ship that was part of a navel fleet assembled outside of the Monster Islands, which soon came under attack by the Devonians. Destoroyah attacked the fleet and killed Mechagodzilla's pilot, though the ship and Mechagodzilla itself were saved by Jet Jaguar, though he quickly realized that he was no match for Destoroyah. Noticing Mechagodzilla, Jet Jaguar shrunk to human size to pilot Mechagodzilla and quickly activated the mech’s Absolute Zero Cannon, allowing him to freeze Destoroyah and shatter the monster's body.

Years later, Rhizon, the leader of the Cryog aliens, held a weapons demonstration for world leaders under the guise of a Russian warmonger named Dyachenko, during which he unveiled yet another version of Mechagodzilla - a cheaper, yet deadly, mass-produced model. As part of the demonstration, Anguirus was lured to a Mechagodzilla unit disguised as Godzilla. After shedding its disguise, the Cryog Mechagodzilla unleashed a volley of finger missiles and Space Beams onto the smaller kaiju. While Anguirus refused to back down and eventually got a few hits in, his persistence only allowed Mechagodzilla to test more of its wide array of weapons against Anguirus, as well as its physical capabilities when it tried to break the monster's jaw. Eventually, Anguirus collapsed and was left for dead, though his body was discovered by the CKR shortly thereafter, prompting them to mobilize their own Mechagodzilla alongside an investigative team to learn more about what had happened to the fallen kaiju. Upon arrival, the CKR discovered that Anguirus was still alive and used their Mechagodzilla to restrain him, allowing them to discover missiles embedded in his underbelly.

The Cryogs' Mechagodzilla army in Godzilla: Rulers of Earth #14

Concurrently, Godzilla attacked Boston, Massachusetts, prompting U.S. Senator Payne to enlist the help of the disguised Rhizon, who deployed four of his Mechagodzilla units to destroy Godzilla once and for all. The Mechagodzilla army bombarded Godzilla with a volley of missiles and were able to briefly incapacitate him after he bit one of the Mechagodzilla's hands, which detonated its missiles directly into his mouth. After Godzilla got back to his feet, the Mechagodzillas deployed their Defense Neo Barriers that shielded them from his attacks until the King of the Monsters used his nuclear pulse, which disrupted their shields. By concentrating on a single target, Godzilla managed to knock one of the Mechagodzillas down, stomp its head into the ground, and blast it apart with his atomic breath before using its severed arm to beat another unit back. One of the Mechagodzillas then initiated a Beam-Fight which Godzilla won, allowing him to defeat it while also knocking the head off of another unit in a physical attack. After one of the remaining Mechagodzillas began bombarding him with its Space Beams, Godzilla lifted and threw the headless Mechagodzilla at it and appeared to dispatch both in a great explosion just before he was abducted by the Cryog's ultimate weapon - Mecha-King Ghidorah. Meanwhile, in Russia, Rhizon ordered two more Mechagodzilla units to shoot down the CKR's Mechagodzilla, downing it just outside of the facility that they were meant to transport Anguirus to - a battle arena that Rhizon had constructed. Mecha-King Ghidorah brought Godzilla to the facility, where two of the Cryog's Mechagodzillas assisted the cyborg dragon by restraining Godzilla. The trio overwhelmed Godzilla until Anguirus, who had managed to free himself from the CKR Mechagodzilla's grasp, entered the facility and immediately mauled one of the Mechagodzilla units, catching it by surprise and destroying it. The remaining Mechagodzilla fired upon Godzilla, but the King of the Monsters dodged the attack and tricked Mecha-King Ghidorah into attacking it. With a well-timed shot with his atomic breath, Godzilla managed to destroy the last Mechagodzilla unit and cripple Mecha-King Ghidorah. Defeated, Rhizon called for his remaining forces to evacuate the planet, revealing that only two of his Mechagodzilla units had survived their various encounters with Godzilla and Anguirus.

A few weeks later, after his warship came under attack by SpaceGodzilla, Rhizon sent the two Mechagodzillas out to fight him. However, as predicted by one of his underlings, the Mechagodzillas were frozen by the cold vacuum of outer space, allowing SpaceGodzilla to immediately destroy one by impaling it with his tail. While the other was able to fire its Space Beams, it too was destroyed by SpaceGodzilla. The Counter-Kaiju Reaction Forces repaired their own Mechagodzilla yet again and later deployed it alongside MOGUERA and a massive fleet of warships to counter an invasion by the Cryog emperor's new monsters, the Trilopods. Upon landing outside of the Trilopod hive in Los Angeles, Mechagodzilla and MOGUERA quickly joined forces with the severely outmatched Godzilla and battled the various Trilopod hybrids that had been released from the hive. Mechagodzilla managed to freeze and shatter the Baragon-Trilopod, though it was knocked down by the Rodan-Trilopod and later pounced on and seemingly destroyed by the Varan-Trilopod and Sanda-Trilopod. Fortunately, the mechs managed to buy enough time for King Caesar to free the other monsters from the Trilopod hive, who joined Godzilla in a great final counterattack in which the kaiju of Earth thwarted the invasion.

While the Cryog were seemingly wiped out in the battle, a single Cryog Mechagodzilla unit was later seen being repaired alongside Gigan in an unknown location.

Godzilla: Cataclysm

Mechagodzilla in Godzilla: Cataclysm

Mechagodzilla was among the countless weapons deployed against the giant monsters wreaking havoc across the planet to little success, prompting the military to initiate a plan of using human psychics to infiltrate the minds of the kaiju in efforts to control them. However, the project only caused the monsters to go berserk and caused a great monster apocalypse that led to the downfall of civilization.

Godzilla: Oblivion

The Mechagodzilla army attacks Godzilla in Godzilla: Oblivion

After opening an interdimensional portal into an alternate Earth - dubbed "Earth-2" - Dr. Eli Talbert and his team were quickly ambushed by a tiny Rodan. Fortunately, the team was saved by a defense measure built by the people of that world - a small Mechagodzilla. Mechagodzilla initially had the upper hand until a swarm of Rodans suddenly descended upon it, completely overwhelming the mech and forcing Dr. Talbert's team to flee.

Later, with Godzilla wreaking havoc on Earth-1 following the death of King Ghidorah, a member of Dr. Talbert's team, Ridley, revealed that she had salvaged some of the metals left behind from the Earth-2 Mechagodzilla they encountered and used their team’s replicators to build an entire army of their own small Mechagodzillas. The Mechagodzilla army was deployed against Godzilla over the open ocean, though the first Mechagodzillas to engage were instantly vaporized by Godzilla’s atomic breath on the onset of their assault. Nevertheless, the Mechagodzillas continued to arrive and battled Godzilla with their beam weapons, providing a successful diversion while Dr. Talbert's team salvaged the carcass of King Ghidorah and worked to revive him as the more powerful Mecha-King Ghidorah. When Godzilla eventually destroyed all of the Mechagodzillas with his atomic breath and claws, he journeyed to Dr. Talbert’s base and engaged Mecha-King Ghidorah just as the cyborg was finished.

Godzilla Rivals: Vs. King Ghidorah

Dr. Ogilvy Hu kept a Mechagodzilla unit in his lab alongside various other weapons that he had created.

Godzilla Rivals: Rodan Vs. Ebirah

After escaping containment within the ParaSOL scientific research facility that orbited the Earth, Rodan and Ebirah began the long plummet back to the surface within the space elevator connecting ParaSOL to Tokyo. Following several failed attempts to stop their descent, including one that involved entangling the kaiju in Mothra silk, Dr. Fatima Ogbannaya finally requested assistance from Mechagodzilla. She chalked up her reluctance to call upon the mech for two reasons, with the first being that Mechagodzilla had a limited rocket range and that he becomes increasingly difficult to control the further he is from base. However, the primary reason was that his activation was guaranteed to attract the attention of Godzilla. Emerging from a hangar in Tokyo, Mechagodzilla quickly entered the space elevator and flew up to intercept the falling kaiju. Upon reaching them, Ebirah immediately lashed out with his claws, though Mechagodzilla dodged the attack, grabbed onto some of the residual Mothra silk still wrapped around the kaiju, and used it to tie Ebirah and the unconscious Rodan together. With both kaiju temporarily incapacitated, Mechagodzilla hoisted them onto his back and used his thrusters to slow their descent. Though the mech hit the ground with a great deal of force, he was able to land safely on the surface with both monsters, thus ending the threat of Japan's annihilation. With Godzilla having been detected in Tokyo Bay, Mechagodzilla swiftly returned to his base, which in turn caused Godzilla to return to the bottom of the bay and prevented further chaos.
