GIGAN!!! Rise!

Controller of Planet X (Godzilla Final Wars)

Gigan (ガイガン,   Gaigan) is an alien cyborg kaiju who first appeared in the 1972 Toho Godzilla film Godzilla vs. Gigan.

The ultimate weapon of the M Space Hunter Nebula Aliens, Gigan was deployed to Earth alongside King Ghidorah to aid in the invaders' conquest of the planet. Gigan and King Ghidorah began their assault on Tokyo, where they were confronted by Godzilla and Anguirus. After a grueling battle, Gigan and King Ghidorah both retreated into outer space. The following year, in Godzilla vs. Megalon, the Nebulans sent Gigan back to Earth to aid their allies, the Seatopians, in their assault on the surface world. Gigan joined forces with the Seatopians' guardian Megalon, but was sent retreating once again by the combined efforts of Godzilla and Jet Jaguar. In the television series Zone Fighter, Gigan was now under the control of the Garogas and had joined the ranks of their Terror-Beasts. The Garogas upgraded Gigan and sent him to Earth, where he fought Godzilla once again but was ultimately killed in battle with Zone Fighter. Gigan's next film appearance came in Godzilla Final Wars almost 30 years later, where he was under the control of the Xiliens. Gigan engaged Godzilla in Antarctica and was defeated, but the Xiliens upgraded him and sent him to Tokyo to aid Monster X in the final battle against Godzilla. Mothra soon intervened on Godzilla's behalf, sacrificing her life to destroy Gigan once and for all.

Despite the generally low-perceived quality of his first two film appearances, Gigan has remained a popular member of Godzilla's rogues gallery, and has been featured in numerous comics and video games over the years. Gigan's popularity contributed to his revival for Godzilla Final Wars, as he was one of director Ryuhei Kitamura's favorite monsters, and Toho released two short films in 2022, Godzilla vs. Gigan Rex and Fest Godzilla 3: Gigan Attacks, to celebrate the 50th anniversary of his debut film.


Gigan's Japanese name, Gaigan, was derived from a nickname for actor Yujiro Ishihara, "nice guy" (ナイスガイ,   naisu gai), combined with the word for goose, gan (雁); both were influences on Gigan's design in his visor and body shape, respectively.[15] The name may have also been chosen as a contraction of "geiger counter," spelled in Japanese as ガイガーカウンター (gaigā kaun).[16]

The incarnation of Gigan from Godzilla Final Wars is designated Gigan (2nd Generation) (ガイガン(2代目),   Gaigan Nidaime).[17] Gigan's upgraded form in the film is officially named Modified Gigan (改造ガイガン,   Kaizō Gaigan). Early figures of the monster, including those of Bandai's Movie Monster Series and Chogokin, instead called the form Power-up Type (パワーアップ・タイプ,   Pawāappu Taipu),

In the animated short film Godzilla vs. Gigan Rex, the numerous green Gigan units are known as Gigan Miles (ガイガンミレース,   Gaigan Mirēsu), which comes from miles, the Latin word for "soldier." The red Gigan who commands the Gigan Miles is called Gigan Rex (ガイガンレクス,   Gaigan Rekusu), whose name comes from the Latin word for "king," rex.


Redrawn concept art of Gigan based on Takayoshi Mizuki's original design

Gigan was designed by Shōnen Magazine illustrator Takayoshi Mizuki, based on ideas by Teruyoshi Nakano.[note 1] Mizuki was contacted in early 1971 by Toho production manager Masao Suzuki to design a space monster for a new Godzilla film.[18] According to Nakano, "the idea for Gigan was to create a monster with quite a different shape,"[19] wanting for the monster to be akin to a "richly colored dinosaur"[16] and also being inspired by the designs of the multilayered jūnihitoe kimonos worn by Japanese court ladies.[16][20] Mizuki created two potential looks for Gigan, a "triangular" design reminiscent of his final appearance, and a "circular" design sporting a number of hemispheres across its body.[18] Mizuki aimed for a "sharp, florid" look when creating Gigan's design, and took inspiration after birds; he based Gigan's form on migratory birds such as geese, and adopted the sharpness of an eagle from his neck up.[18] Gigan's scythe-like appendages were said to have been inspired by Alien Baltan from the Ultra Series, due to Mizuki frequently drawing Ultraman artwork for magazines,[15] while the monster's signature visor eye was inspired by a pair of sunglasses worn by actor Yujiro Ishihara in 1959's The Echo of Love, which Mizuki had seen as a student in 1960.[18] Originally, Gigan was to have a single eye beneath the visor which would move along a horizontal axis, though this was not preserved in the finished film.[18] Mizuki was also responsible for conceiving nearly all of Gigan's weapons and abilities, such as his rotating chest saw and the canonical functionality of his head horn as a radar antenna.[18] While Mizuki created concepts for the laser beam that Gigan is often depicted as having in publicity stills,[18] it was actually Teruyoshi Nakano who hatched the idea: "Many statues of Buddha have an aura around their heads like angels in western paintings. I read an article about a strange ray shooting from a human forehead like ESP, or a sixth sense," he commented on the inspiration behind the ability.[19] Nakano later decided against the idea, however, stating that it "doesn't fit a monster, it fits a human, or a superhuman."[19]

Takeshi Kimura was the first to write Gigan into a story treatment for the twelfth entry in the Godzilla series, entitled Godzilla vs. the Space Monsters: Earth Defense Directive. In the draft, Gigan, accompanied by fellow space monsters Megalon and King Ghidorah, would have been under the control of an evil alien brain called Miko, causing disasters as part of a scheme to seize control of the planet.[21] As Miko prepared to destroy the capital of Japan, he sent the monsters to an international science exhibition to implant his life support system into the ancient Incan idol Majin Tuol, who was being kept there.[21] However, as Gigan attempted to cut the statue open, it came alive to ward off the invaders, with Godzilla and Anguirus arriving to join him.[21] This treatment would soon be followed by two more—The Return of King Ghidorah and Godzilla vs. Gigan: The Return of King Ghidorah, both penned by Shinichi Sekizawa—which laid the groundwork for what would ultimately become Godzilla vs. Gigan. Gigan was later considered for a 1973 Godzilla vs. Mechagodzilla precursor, Showdown in Zanpamisaki: Godzilla vs. Mechagodzilla. In this story, Gigan would have been deployed by the invading R Aliens to fight Godzilla, Anguirus, and King Balgan in Okinawa alongside their own mechanical creation, Mechagodzilla.[13] Gigan was ultimately dropped from the film. The cyborg was also considered for the rejected film concept S.O.S. Tokyo! Godzilla's Suicide Strategy, written by Hiroyasu Yamaura sometime between 1973 and 1978. A pawn of the Titan Aliens from Galaxy 23, Gigan would have possessed new hurricane-generating powers and been deployed alongside the robotic monster Chamelegon in an effort to seize control of Japan.

Kenpachiro Satsuma emerges from the Gigan suit during filming of Godzilla vs. Gigan

Gigan's suit was modeled by Nobuyuki Yasumaru, who took over for Teizo Toshimitsu as Toho's chief modeler in 1971.[15] The suit's eye was made of acrylic resin, while the beak, horns, and scythes were made using fiber-reinforced plastic, or FRP.[15] Initially, the FRP components were cast solid, and needed to be hollowed out after complaints of difficulty moving from suit actor Kenpachiro Satsuma; of Yasumaru, Satsuma explained "His priority is design, not operation of the suit or the actor."[21][Missing page number] This would not be the only alteration made to the suit during production, however. Gigan's neck was at first made considerably longer, and the suit's fins were more rounded.[22] This version of the suit was used in the film to depict Gigan attacking a port, and was refurbished shortly thereafter.[22] Gigan's fins were made of white Georgette fabric taken from a stage curtain.[15] While Takayoshi Mizuki envisioned Gigan possessing yellow feathers,[16] these were replaced by golden scales during the modeling process, cast from a mold of King Ghidorah's scales that had been left in the Toho studio.[15] Gigan's buzzsaw could be replaced with a rigged piece, consisting of a wooden strip with blade pieces attached.[7] This could be fed through a remote-controlled[5] motor mechanism created by Akinori Takagi, which moved it up and down along a cam, mimicking the appearance of a rotary saw at high speed.[7] In addition to the Gigan suit, an approximately 1 meter-long scale model of the monster in flight was created out of styrene.[15] It was equipped with a mechanism to spray Freon gas[15] from either side of its wings, simulating him cutting through the air at high speed. A giant model of Gigan's claw was also used to depict him swatting at fighter jets.[7]

A Gigan suit was made for attraction purposes sometime during the early Heisei period. "Hurricane" Ryu Hariken borrowed the suit and shot photos of it in 1993.[23] This suit, or a similar one, was used in an Ultraman stage show at Hero Festival '96.[24]

Gigan concept art for Godzilla Final Wars

Gigan was heavily redesigned by Yasushi Nirasawa for Godzilla Final Wars in 2004. Nirasawa intentionally shied away from the character's original design, nixing his scales and adding concealed weapons to his body.[15]:308 Nirasawa also prepared concept art for Gigan's Modified form, an idea of director Ryuhei Kitamura's.[15]:308 The monster was portrayed by Kazuhiro Yoshida, who doubled as the actor for Hedorah in the film. Modeling company Star Train produced two new suits and a flying prop, supervised by Shinichi Wakasa.[25] The suits were designed to be modular and could split apart into individual pieces, allowing for his transformation into Modified Gigan. Motors installed in the arm pieces drove his chainsaw blades, while lights in the visor allowed it to glow. A separate neck stump piece was also created for Gigan's decapitation scene.[26]:96 At least one more suit, which was artificially weathered, was used to represent the mummified Gigan.[15]:308 In addition to the practical effects, several shots of Modified Gigan were computer-generated. One of the regular Gigan suits later turned up in original footage shot by Koichi Kawakita for the 2004 Pachinko game, CR Godzilla 3S-T Battle.


Gigan is truly a strange monster, sporting a circular saw weapon located in his frontal abdominal region, large steel hooks for hands with smaller ones for toes, spikes running down his tail, three, large fin-like sails on his back and a red cybernetic visor for an eye. He also bears various avian characteristics, such as a "crest" made of metal spines and a metal beak. In the Showa series, Gigan's skin was a dark green color and he possessed golden scales over several parts of his body.

In Godzilla Final Wars, Gigan's appearance was changed to make him appear more cybernetic. In this film, Gigan's skin is now a dark blue, his body is much thinner and more streamlined, and there are wire-like structures running across his body. When Gigan is revived as Modified Gigan, his hook hands are replaced with double-pronged chainsaws in addition to a larger crest and reinforced neck.


Gigan is sometimes considered to be Godzilla's most brutal and violent opponent. The 1992 book Special Graphix Godzilla vs. Mothra contrasts Gigan's personality with King Ghidorah and Mechagodzilla, two of Godzilla's other recurring foes from the Showa series. While King Ghidorah is described as a "dignified villain," Gigan is said to be a "bloodthirsty, ferocious cutthroat" in contrast to Mechagodzilla being a "consistently coldhearted and composed professional."[27][note 2] Gigan is shown to be very vicious and sadistic in combat, preferring to shred his opponents up close with his hook hands and buzzsaw. Gigan is also not above continuing to attack his enemies while they are down, as shown in his debut film, where he repeatedly struck and stabbed Godzilla with his Hammer Hands while the latter was still left floored by the Godzilla Tower. According to Gigan's suit actor Kenpachiro Satsuma, he made the conscious decision to portray Gigan as enjoying the destruction he causes.[28] However, at least in the Showa series, Gigan appears to be a bit of a coward, attempting to retreat and leaving his ally at the mercy of his enemies as soon as the tide of battle turns against him. In Godzilla Final Wars, Gigan is shown to be somewhat incompetent, having his head easily blown off by Godzilla's atomic breath and later slicing his own head off with two razor discs intended for Mothra.

In Godzilla Island, Gigan actually becomes an ally of Godzilla after being defeated by him, and assists him and the other residents of Godzilla Island in fighting off invading monsters. This was the first instance of Gigan being portrayed in a benevolent light. Gigan is also portrayed as a heroic monster in the novel GODZILLA: Project Mechagodzilla, the official prequel to the GODZILLA anime trilogy, where he is utilized by the United Earth to combat Godzilla multiple times during "Operation: Long March," saving the lives of many soldiers in the process.


In the Showa series, Gigan is a type of space dinosaur that was transformed into a cyborg by the M Space Hunter Nebula Aliens in order to be used in their attempted invasion of Earth.[10] According to Godzilla Movie Studio Tour, Gigan's reappearance in Zone Fighter was only a few months after the events of Godzilla vs. Megalon.

In Godzilla Final Wars, Gigan is an ancient cybernetic monster that was sent to Earth by the Xiliens 12,000 years ago, where he was defeated by Mothra and subsequently mummified. In the year 20XX, Gigan's mummified corpse was discovered by the Earth Defense Force in Hokkaido, and the monster was later reactivated by the Controller of Planet X during the Xiliens' invasion.

In the continuity of the GODZILLA anime trilogy, Gigan was a monster discovered in hibernation on the seabed off the coast of Siberia. Gigan was modified using Exif and Bilusaludo technology and gradually converted into a cybernetic biological weapon used against Godzilla.[11]


Showa era

Godzilla vs. Gigan

Gigan was sent to Earth by the M Space Hunter Nebula Aliens to destroy human civilization alongside King Ghidorah. Controlled remotely by the Nebulans from Godzilla Tower, Gigan and King Ghidorah were unleashed in Tokyo. The space monsters ravaged the city, but their rampage was interrupted by Godzilla and Anguirus at a refinery. The monsters began a fierce battle, which gradually moved to the Nebulans' base of operations at World Children's Land. With the aid of the Godzilla Tower's laser cannon, Gigan and King Ghidorah nearly killed both of the Earth monsters. However, a group of humans were able to successfully destroy the Godzilla Tower with explosives, severing the Nebulans' control over the space monsters. While they were able to maintain their assault for a while, Gigan and King Ghidorah were eventually left disorganized and confused without the orders relayed by their masters, and they soon began bickering with one another. This granted Godzilla and Anguirus an opportunity to regroup and mount an assault of their own. This time, the tide of battle was turned against Gigan and King Ghidorah, prompting Gigan to attempt a retreat. Godzilla shot down Gigan with his atomic breath, then he and Anguirus turned their attention to King Ghidorah. Finally, King Ghidorah flew away into space, and was joined by Gigan, leaving the Earth safe for the time being.

Godzilla vs. Megalon

A year later, the Seatopians called upon the M Space Hunter Nebula Aliens for aid as they launched an assault on the surface world. The Nebulans sent Gigan to aid their allies, and he joined the Seatopians' guardian Megalon in battle against Jet Jaguar. Godzilla soon arrived to assist the robot, but the two found themselves locked in a difficult battle. Eventually, Godzilla and Jet Jaguar regained their strength and began to regain the upper hand. After Jet Jaguar broke Gigan's arm and Godzilla shot him down when he took to the air, he quickly retreated back to space, leaving Megalon at the mercy of the two heroes, with the battle now firmly against him.

Zone Fighter

Gigan in Zone Fighter

After his battles with Godzilla and Jet Jaguar, Gigan found himself under the control of the Garogas, who outfitted his claws with explosive charges. Following a scheme of the Garogas' to trap Zone Fighter inside of a junked car, Godzilla appeared to drive off the aliens, but was met by a Terror-Beast Missile containing Gigan, who flew down with drogue parachutes after the Terror-Beast Missile had exploded. The rival monsters again locked in combat, Gigan was quickly dispatched, and Godzilla turned to save Zone Fighter who was still in peril. Gigan was, however, merely feigning death, and returned to his feet to attempt a sneak attack on Godzilla. Noticing this, Zone Great summoned Bolt Thunder to halt the cyborg, again flooring him and allowing Godzilla to cut the power to the junkyard's compactor. Godzilla then thoroughly beat Gigan, leaving him motionless after repeatedly slamming him into the ground with his tail, and left the scene believing himself triumphant. Though, this would not be the end of the space monster, who miraculously revived himself. Free from his automotive imprisonment, Zone Fighter grew to giant size to engage the persistent monster in a final duel. After a brief scuffle, Gigan managed to restrain Zone and utilized his upgraded claws to detonate one of the charges against the hero's head. Zone was not fazed for long, however, as he quickly rolled away and destroyed Gigan's remaining explosive with his Proton Beam. No longer possessing the edge, Gigan was bested in combat and, this time unable to retreat, was struck by a finishing blow. With Zone standing victorious, Gigan's visor dimmed and his mouth flooded with foam before he finally exploded, thus concluding the cyborg monster’s reign of terror once and for all.

Heisei era

Get Going! Godzilland

Gigan lived with many other kaiju on an island called Godzilland. He rarely interacted with Godzilla and his friends, instead typically hanging around King Ghidorah and Moguera.

Godzilla Island

Story 5

In Godzilla Island episodes 31-40, when Zagreth gets upset on the reports of her failures while reading a newspaper, a M Space Hunter Nebula Alien crawls into view and says to Zagreth that it's here to help her conquer Godzilla Island, so the M Space Hunter Nebula Alien introduces Gigan to Zagreth, which impressed her, and Gigan heads down to earth.

When Godzilla sees Gigan, Gigan levels off and starts a scan on Godzilla, and succeeds in doing so; Gigan then prepares to leave as Torema arrives on the scene, but Gigan flies over Torema's ship, and Zagreth was annoyed when Gigan didn't even bother to fight. Gigan then fires an arrow with a note tied onto it to Godzilla Island from space, it turns out that the note said that Gigan has challenged Godzilla to a battle at sunrise, so Godzilla heads out to battle, only to be stopped by King Caesar, who then warns Godzilla that Gigan is too strong and needs to prepare before the battle, but Godzilla roars in defiance, then Torema begs Godzilla to listen, but Godzilla marches past King Caesar, refusing to listen.

Godzilla finally reaches the battle site and finds Gigan waiting. The two monsters then begin to wait through the night before attacking, when the sun rises, Gigan reflects the sunlight off its claw, blinding Godzilla by the reflection. Gigan sees its opportunity and starts to charge at Godzilla, only for Godzilla to regain his sight, causing Gigan to halt its charge, and leap back to where it started attacking from.

Zagreth starts getting frustrated that Gigan isn't fighting Godzilla, so she calls out Battra, only for Gigan to fire its Cluster Beam at Battra. The M Space Hunter Nebula Alien alien then assures Zagreth that Gigan can defeat Godzilla on its own.

Godzilla and Gigan continue to face off as everyone waits in anticipation. When a landslide falls between Godzilla and Gigan, the two monsters begin to charge, but unfortunately, Godzilla goes down, much to everyone's surprise. Gigan then approaches the fallen Godzilla when Mothra suddenly appears, and attacks Gigan with her scales, then Rodan appears, picks up Godzilla, and flies away with Godzilla as Mothra follows.

Gigan watches, but turns away as Godzilla escapes. At King Caesar's healing spa, Godzilla admits to King Caesar that he wasn't ready to face Gigan and should've listened in the first place. King Caesar then tells Godzilla that he needed to use powers he's never used to defeat Gigan, and can train Godzilla how to use those powers. Gigan then appears, much to Godzilla and King Caesar's surprise.

However, it did not attack, but instead, enjoys the hot spa, as Godzilla and King Caesar watch. Gigan then rises out of the spa and states that he had been fairly struck by Godzilla, which impressed him. He challenges Godzilla at sunrise for the final battle, and Godzilla accepts Gigan's challenge. Before their final battle, Godzilla is seen meditating as Rodan flies by, King Caesar approaches as Godzilla continues to meditate. King Caesar taps into Godzilla's inner power, then walks away.

The next day, Godzilla has reached the battle site, and Gigan flies into position while King Caesar's gathered all the monsters, and warns them not to interfere in Godzilla's battle with Gigan. The monsters disapprove, and King Caesar roars in defiance, causing the monsters to step back.

Godzilla then closes his eyes, much to Gigan's confusion, and a green aura surrounds Godzilla, causing Gigan to step back. The green aura disappears and Godzilla opens his eyes. Godzilla suddenly fires his Radioactive Heat Ray aimlessly into the sky. Gigan sees its opportunity and charges Godzilla. In midair, the ray does a 180 and hits Gigan from behind, and everyone is shocked as to what has happened. Gigan looks back to see who attacked it, and Godzilla sees his opportunity and charges Gigan. As Gigan turns back around, Godzilla leaps in the air and strikes with a spinning tail attack, knocking Gigan down to the ground.

The fallen Gigan looks up at Godzilla as the King of the Monsters looks back. Gigan soon falls unconscious, and all the monsters come to congratulate Godzilla, even Torema is happy that Godzilla was able to defeat Gigan. but Zagreth swats the M Space Hunter Nebula Alien alien with her newspaper because the plan's failed.

Story 12

Sometime after their battle, Gigan went to Matango Island to train for a rematch with Godzilla.

Gigan reappears in episodes 117-118 when Godzilla is getting a beat down from Destoroyah and Megalon. At first it would seem like Gigan is helping the two monsters against Godzilla, but as it turns out, Gigan is actually helping Godzilla when Gigan knocks down Megalon. Destoroyah then tries to fly away, but Gigan shoots him down with the Cluster Beam, and Godzilla finishes Destoroyah off with a spinning tail attack, knocking him down. Godzilla and Gigan then drag the two monsters into a cave, and use their respective beam attacks to close in the cave on Destoroyah and Megalon.

Gigan then explains to Godzilla that he wants to be the one to defeat him, fair and square, and tells him not to die until that day comes. Gigan flies off while Godzilla goes back to Godzilla Island to help fight-off against Mecha-King Ghidorah.

Story 16

Gigan once again reappears in episodes 169-178 when Misato Jinguji goes on an expedition to Matango Island in her ship, Gigan is seen training by throwing rocks up in the air and slicing them in two, so Misato then reports this back to Beisuke Jinguji. Landes sends Cameron to ask if Gigan would like to join them in conquering Godzilla Island, but Gigan is uninterested and flies off.

The Giant Dark Emperor appears in space to yell at Landes, but she cries and he gives her a new monster, Dororin, to send out on earth. Dororin then crashes on Matango Island, shape-shifts himself into Godzilla, and smashes a rock on Gigan's head while Gigan was meditating.

Then he shape-shifts into Gigan itself, and flies off. Misato also arrives on Matango Island because Lucas got an alert, and Gigan tells her Godzilla attacked it, and Gigan flies to Godzilla Island to fight Godzilla. Meanwhile back in Godzilla Island, Dororin, while disguised as Gigan, smashes a rock on Godzilla's head. Beisuke Jinguji radios Misato, and tells her that Gigan is here, but she tells him she's with Gigan. Soon enough, the real Gigan comes and fights Godzilla.

So far, neither monsters are falling or getting hit by blows that brought them down in previous battles. The battle continues despite Misato getting upset, and also the fact that Beisuke Jinguji is piloting Mechagodzilla to fight Dororin to protect G-Guard Base. Godzilla refuses to stop fighting to help fight Dororin. But then Moguera, piloted by Nao Koda, comes in-between Godzilla and Gigan and tells Godzilla to help fight-off against Dororin, so Godzilla decides to go because his friends are more important than his battle honor, and Gigan follows.

While Misato uses the computer and gets a clue on how to beat Dororin, Godzilla comes in and blasts Dororin with his Radioactive Heat Ray and takes over the fight, but Dororin grabs him from behind. Then Gigan comes in and attacks Dororin. And then Fire Fighter Jet Jaguar, piloted by Misato, comes in and uses its fire hose, melting the shape-shifting monster away, the spirit then flies up to the air, only for Gigan to smash it with its claw and finally, Gigan flies away, but not before it fires an arrow with a note tied onto it to ground from space.

Millennium era

Godzilla Final Wars

In 20XX, Gigan's mummified remains were discovered in Hokkaido by the Earth Defense Force. According to the Shobijin, Gigan invaded the Earth thousands of years ago, but was defeated by Mothra. Gigan was soon reactivated by the Xiliens to help them conquer Earth. He chased the Gotengo to Antarctica to stop it from awakening Godzilla. He nearly destroyed the ship, but he was blasted by Godzilla's atomic breath. Gigan battled Godzilla, trapping him in barbed wire and pulling him toward his buzzsaw. However, Godzilla fired his atomic breath at Gigan's head, decapitating him and causing him to fall to the ground.

Modified Gigan
Modified Gigan in Godzilla Final Wars

After being decapitated in his battle with Godzilla, Gigan was repaired and upgraded by the Xiliens into Modified Gigan (改造ガイガン,   Kaizō Gaigan), with a different head, braces to protect the back of his neck, slits in his body that fire razor discs and, most notably, a pair of two-pronged chainsaws instead of a pair of hooks. Modified Gigan was released by the Controller of Planet X to battle Mothra, and seemingly defeated her after slicing off part of her wing. Gigan then attempted to help Monster X in his battle with Godzilla, slicing him in the chest while Monster X held him still. Godzilla wriggled in Monster X's hold, causing them to shift and Gigan's chainsaws to hit Monster X by accident. Mothra flew into the battle and knocked Monster X and Gigan over. Gigan shot his discs from his chest at Mothra, but she dodged them and the discs spun around and headed back to Gigan. Gigan then blasted Mothra with his laser beam, causing her to burst into flames. Gigan struck a victory pose, but his razor discs flew back and sliced his head off. Gigan wandered around blindly after his head was severed until Mothra, now on fire, flew into him, causing him to explode and die.

Reiwa era


Gigan (bottom right) with other members of the Gigan Clan in Godziban

The Gigan Clan was a family of powerful space kaiju that were rivals to the Godzilla Clan. The clan was led by King Gigander and Mother Gigarian, who themselves were the parents of Gigan, his older sister Lady Gigana, and his younger sister Girly Galrin.

Seeking to prove himself as one of the universe's strongest monsters, Gigan came to Earth in a meteor and landed on Godzi Godzi Island to challenge a member of the Godzilla Clan. While seeking to pick a fight, he promptly attacked Baragon and Anguirus with his Hammer Hands. Moshu-Moshu crawled by him without incident, but a vengeful gleam appeared in her eyes. After Gigan attacked Little, Godzilla-kun was provoked into taking his challenge, defeating him and burying him underground. When Little ended up digging Gigan out of his prison, he befriended the young kaiju, who proceeded to train Gigan's willpower and endurance through unusual methods. This unusual friendship would lead Gigan to defend Little from King Ghidorah, who saw the fellow "villain kaiju" as a potential ally, but Gigan insisted that he was the only one allowed to defeat the Godzilla Clan. When the three-headed dragon beat Gigan to near death, Little's cries for his friend would end up reviving the cyborg. Gigan's courage ended up gaining Godzilla-kun's respect, with the promise that they could have a proper duel when he trained to be stronger.

The recurring hand-drawn segment Gigan, Slice! sees the Millennium version of Gigan showcasing the sharpness of his claws by way of various mundane tasks.

Godzilla vs. Gigan Rex and Godzilla vs. Megalon

Main articles: Gigan Miles, Gigan Rex.

The powerful cyborg Gigan Rex led an army of Gigan Miles in an attack on Japan, only to be opposed by Godzilla, appearing for the first time in a quarter-century. Despite their teamwork, and the willingness of the Gigan Miles to sacrifice themselves to empower Gigan Rex, Godzilla defeated the cyborgs with his white-hot atomic breath. Gigan Rex's corpse would be seized by a Seatopian agent, who would siphon power from the cyborg as a sacrifice to awaken Megalon.

Gigan battles Godzilla in Fest Godzilla 3: Gigan Attacks

Fest Godzilla 3: Gigan Attacks

As Godzilla walked into a city, Gigan suddenly appeared in the sky. Landing on the ground, Gigan engaged Godzilla for a time until Godzilla began to charge his atomic breath. Gigan blocked the blast with his Hammer Hands, however, and returned fire with a laser of his own. More laser blasts followed as Godzilla attempted to charge toward him, eventually reaching him. Godzilla was met with a slash across the face from one of Gigan's claws, but ducked under several more swings. Later, as the battle raged on, Godzilla evaded another of Gigan's slashes, instead slicing a nearby tower in half. Eventually, Godzilla landed a punch to Gigan's face, damaging his laser aperture. Gigan attempted to charge a beam, but the device merely sparks. Gigan let out a series of panicked shrieks before angrily charging towards Godzilla, activating his chest-mounted buzzsaw. Gigan forcefully stabbed both of his claws into Godzilla's hide, pulling him into the spinning saw. Godzilla fell backward through a bridge, now bearing a massive wound on his torso. As Godzilla laid helplessly on the ground, Gigan slowly approached, brandishing his claws. Gigan prepared to finish Godzilla off, but Godzilla suddenly grabbed Gigan's claws and returned to his feet. Restraining Gigan's arms, Godzilla blasted the cyborg with his atomic breath at point-blank range, causing him to fall to the ground and erupt into a massive explosion.


Antigravity flight

Gigan flies through space encased in a diamond alongside King Ghidorah in Godzilla vs. Gigan

Gigan is capable of flying at speeds of up to Mach 3 while in Earth's atmosphere and Mach 400 while in the realm of space.[15] The latter is achieved by encasing himself in a diamond, and is the fastest any kaiju in the Showa Godzilla series is capable of traveling, tied with the original King Ghidorah. The diamond explodes when Gigan emerges from it, and jets at the tips of his wings leave behind a smoke trail while flying. Gigan's flight normally assists in interstellar travel and is utilized less frequently during battle situations. While using his flight during a battle, Gigan will often engage in aerial slams to continuously topple his opponents without giving them a chance to counter, or even get up.

In Zone Fighter, Gigan was fitted with a set of deployable drogue parachutes to slow his speed down upon approaching a battle after being released from the Terror-Beast Missile he was deployed in.

Gigan's flight is omitted from most of his video game appearances, although he can perform a move where he briefly flies past an enemy and slices it with his buzzsaw in the Atari/Pipeworks games.

Hooked appendages

Gigan destroys a building with his Hammer Hand in Godzilla vs. Gigan

Gigan's forelimbs sport a pair of large metal hooks, which in the Showa series are either called Hammer Hands (ハンマー・ハンド,   Hanmā Hando)[4] or Hammer-claw Hands.[12] In the Atari/Pipeworks Godzilla video games, they are instead referred to as Hammerclaws. Gigan uses his Hammer Hands to batter and stab opponents, drawing blood from Godzilla after repeated strikes to the forehead.

In Zone Fighter, the tips of Gigan's Hammer Hands were fitted with explosive charges which detonate on contact with an enemy, though they only have one use each. Gigan used on of his claws to restrain the hero by the neck before using one of the charges, which floored Zone Fighter immediately. Gigan's Hammer Hands were also strong enough to survive Zone Fighter's Meteor Proton Beam, a weapon that often kills Terror-Beasts instantly. Godzilla Movie Studio Tour describes Gigan's Hammer Hands as "diamond hard". Before fighting Godzilla, Gigan demonstrated his strength by slamming his claws into a rock formation causing it to shatter. While Godzilla was focused on saving Zone Fighter, Gigan slammed his foot down on Godzilla's tail and used one of his claws to grasp and throw Godzilla down to the ground.

In Godzilla Final Wars, Gigan's forearms end in scythe-like blades, the undersides of which are equipped with dual grappling hooks that can bind an enemy and drag them straight into his buzzsaw. These new scythe-like appendages are officially referred to as the Bloody Triggers (ブラッディ・トリガー,   Buraddi Torigā),[13] while concept art calls the grappling hooks the "Fucking Ancer,"[29] likely a misrendering of Hooking Anchor (フッキングアンカー,   Fukkingu Ankā). In Godzilla: Rulers of Earth, when Gigan is upgraded by the Cryogs, his original Hammer Hands are replaced by Bloody Triggers.

In the 1992-3 Godzilla, King of the Monsters manga, Neo Gigan can fire his hooks on cables capable of restraining Godzilla. He can also shoot Napalm Shells from the open ends of his arms that explode on contact, and were shown to briefly stun Godzilla, though they failed to injure him significantly enough to stop his counterattack.

In the novel GODZILLA: Project Mechagodzilla, Gigan initially possesses extremely long sickle-shaped claws on his hands. After he is injured in his fights with Godzilla and converted into a cyborg, his hands are replaced by sickles and later hyper-vibrating chainsaws.

Bloody Chainsaws

Gigan slashes Godzilla across the chest using his Bloody Chainsaw in Godzilla Final Wars

Following his initial defeat by the recently awakened Godzilla in Godzilla Final Wars, Gigan's Bloody Triggers are replaced by double-pronged chainsaws, appropriately dubbed Bloody Chainsaws (ブラッディ・チェーンソー,   Buraddi Chēnsō).[13] Gigan uses these offensively to slash Godzilla's chest and slice part of Mothra's wing off. He can also plant the appendages on the ground and use them as mock tank treads, propelling him forward at a moderate speed for short distances. This ability is retained in the PlayStation 3 and 4 Godzilla game. Gigan's Bloody Triggers are also eventually replaced by Bloody Chainsaws in Godzilla: Rulers of Earth, which he uses to easily cut through Cryog ships.


Gigan uses his buzzsaw to slice through a building in Godzilla vs. Gigan

Gigan has a buzzsaw-like Rotating Cutter (回転カッター,   Kaiten Kattā) or Universal Cutter[30] built into his abdominal area made of an unknown alien alloy, granting it considerable durability and sharpness. In Godzilla vs. Gigan, Gigan's saw was able to draw blood from both Godzilla and Anguirus. Gigan is able to use his buzzsaw when on the ground and in the air; on the ground, he cut open Anguirus's face after being charged by the ankylosaur. A favored tactic of Gigan is to use his powers of flight along with his buzzsaw in hit and run attacks, slashing his opponent as he races by them, as demonstrated when he sliced deep into Godzilla's shoulder with the buzzsaw as he flew past at high speed.

In Godzilla Final Wars, the buzzsaw is officially known as the Bladed Cutter (ブラデッド・カッター,   Buradeddo Kattā),[13] and was able to lacerate the hull of the Gotengo.

In GODZILLA: Project Mechagodzilla, Gigan instead has a Blade Launcher installed in his abdomen. It launches guided blades that travel through the air until they strike their target. This weapon was noted to be a prototype for one of Mechagodzilla's armaments.


Gigan's forehead aperture flashes after being hit with a boulder in Godzilla vs. Gigan

In addition to his melee weapons, the Showa Gigan was depicted as having a beam aperture set into his forehead just above his visor, called the Laser Knife in Godzilla Movie Studio Tour. Official art would frequently depict him as firing a laser from this device, although he was never shown to actually do so on film. However, in Godzilla vs. Gigan, after Godzilla heaves a rock at Gigan's face, the laser device in Gigan's forehead gives off a quick flash of light, possibly short-circuiting. According to an anatomy description of Gigan, his forehead laser is capable of drying up Lake Biwa in 10 seconds.[31]

Although Gigan never used his laser onscreen in the Showa series, the attack has been featured in some non-film media. Gigan has used his laser in numerous pieces of official print media since the Showa series, including a Zone Fighter manga and the Cinema Shares Godzilla vs. Megalon comic adaptation. Gigan also demonstrated this ability in Godzilla Island and several video games, including Godzilla: Monster of Monsters!, Godzilla and Godzilla: Great Monster Battle, as well as the three Atari/Pipeworks Godzilla games. According to Gigan's Trendmasters collectible card, his forehead laser is actually an atomic energy weapon, similar to Godzilla's own atomic breath. A purple version of the laser is utilized by Gigan in the short film Fest Godzilla 3: Gigan Attacks.

Gigan fires his Gigarium Cluster at a building in Godzilla Final Wars

In Godzilla Final Wars, Gigan's laser blast was finally revealed on screen, though it had been heavily altered from the original concept. Rather than being fired from a forehead laser device (the aperture had been replaced with a non-faceted ruby gem), it was instead fired from Gigan's eye itself. It also was no longer a traditional laser, but a large energy blast that, in a manner similar to a cluster bomb, would split into smaller explosive bolts of energy upon entering close range of a target, saturating the target in multiple hits simultaneously. The eye beam has been officially titled the Scattered Light Beam Gigarium Cluster (拡散光線ギガリューム・クラスター,   Kakusan Kōsen Gigaryūmu Kurasutā),[26] though it is instead called Giganume Cluster when used by Modified Gigan in the PlayStation 3 and 4 Godzilla game. According to Godzilla Final Wars Super Complete Works, Modified Gigan was equipped with a stronger version of the Gigarium Cluster, with it being able to "set fire in an instant."[26] A similar attack appears in the Atari/Pipeworks games, but the beam scatters the instant it leaves Gigan's eye, has a limited range, and is referred to as Shotgun Blast. In GigaBash, Gigan can charge up his laser to either scatter at a certain distance or completely scatter and cover a wider area at the cost of shorter range.

Bladed Slicer

Gigan fires his Bladed Slicers at Mothra in Godzilla Final Wars

After being repaired and upgraded following his initial fight with Godzilla in Godzilla Final Wars, Gigan displayed the ability to fire guided razor discs called Bladed Slicers (ブラデッド・スライサー,   Buradeddo Suraisā)[13] from two hidden slots in his upper torso which were able to boomerang back for a second attempt if they initially missed their target. However, if they missed the target again, Gigan would find himself right in the path of his own attack, which ultimately decapitated him and allowed Mothra to defeat him. This attack is referred to as Bloody Slicer in the PlayStation 3 and 4 Godzilla game, in which Gigan also possesses a more powerful version called Surging Wave Blooded Slicer.


In the Showa era, Gigan's tail is tipped with a metal spike, although he was never seen using it in combat.

In Godzilla Final Wars, his tail spike is multi-pronged, and Gigan can extend his tail into the air to stab prey like a scorpion. Gigan uses it to attack Mothra by grabbing onto her, dragging, and then throwing her.


In Zone Fighter, after being sent to ground and hit with an atomic breath, Gigan bit down on Godzilla's tail and refused to let go even after being slammed to the ground repeatedly.

Ninja Revival Technique

In Zone Fighter, Gigan sprang to his feet using the Ninja Revival Technique after Godzilla defeated him. Godzilla 1954-1999 Super Complete Works describes Gigan as "immortal" and explains this as him simply playing dead. Toho Special Effects All Monster Encyclopedia clarifies: "[Gigan] is immortal so long as both of his claws [...] are unscathed." Gigan later damaged one of his claws himself by hitting Zone Fighter with an explosive charge, with the hero targeting the other. Godzilla Movie Studio Tour also explains that a secret device implanted within the claws give him the ability to revive himself. This technique was included in the Super Famicom fighting game Godzilla: Great Monster Battle.


A sprite of Gigan using his flamethrower ability from Godzilla

In the video game Godzilla and the Godzilla arcade game, Gigan has the ability to spew flames from his mouth. Although this ability has never been used in a film, Godzilla Movie Studio Tour confirmed that it is a normal ability Gigan has always canonically had, describing the flames as "deadly heat rays." Godzilla Dictionary (New Edition) describes the flames as having a temperature of 5,000 degrees Celsius, as well as being able to melt steel and being generated from an internal nuclear reactor.


In the Atari and Pipeworks Godzilla games as well as in GigaBash, Gigan is able to teleport across short distances instantaneously in place of flying, allowing him to outflank, surprise, or counter-attack enemy monsters. Gigan's teleportation ability has not been present outside of video games.

S-Class form

In the video game GigaBash, after gathering a sufficient amount of Giga Energy, Gigan can grow to massive proportions, gaining great power and enhanced abilities. Giga Energy is gathered through dealing damage to other Titans or from the surrounding environment.


In GODZILLA: Project Mechagodzilla, Gigan gains the ability to instantaneously regenerate parts of his body that are destroyed by Godzilla's atomic breath after being injected with experimental Nanometal. While the regenerative properties of the Nanometal were sufficient to allow Gigan to withstand Godzilla's standard atomic breath, they could not prevent a particularly powerful blast of atomic breath from completely destroying him.


In GODZILLA: Project Mechagodzilla, Gigan has homing missile launchers installed on his arms.

Gigan appears as a boss in the 1988 Nintendo Entertainment System game Godzilla: Monster of Monsters!.

Godzilla: Unleashed

Gigan in the Wii version of Godzilla: Unleashed

Gigan's Godzilla: Unleashed bio differs slightly in the Wii and PS2 versions in that the latter has contains a different closing sentence.

Height: 95 meters[34]
Weight: 47,000 tons[34]

"Gigan is the vanguard of the Alien Invaders. He is the finest fighting monster the Vortaak have at their command. Gigan is a cyborg infused with Vortaak technology designed to augment his powerful natural combat abilities. This latest upgrade makes him faster, stronger, and more ferocious than ever. Gigan projects powerful alien energy from his single eye to engage opponents at range, though with quick footwork and lightning-fast edged attacks he is clearly designed with close combat in mind. In addition, Gigan has the ability to teleport short distances to confuse and outflank his opponents."

Godzilla (PlayStation 3 / PlayStation 4)

Modified Gigan in Godzilla

Modified Gigan appears as a boss in many levels throughout Godzilla on the PlayStation 3 and 4. He was the final kaiju revealed to be in the original PlayStation 3 release of the game. Gigan attacks with his buzzsaw, razor disks, chainsaw hands, and eye beams. He also charges at enemies with the blade on his head. When defeated, Gigan's head will explode, as it does in Godzilla Final Wars. In the PlayStation 4 version of the game, Gigan is a fully-playable character.

"Gigan is a cyborg kaiju sent by the aliens of M Nebula who were aiming to conquer Earth. It is controlled from the Godzilla Tower found in the amusement park built and operated by the M Nebula aliens. Gigan has a single visor-like eye, a horn on its head, a strange beak-like mouth, and two sharp claws called 'Hammer Hands.' Its most notable feature is a bone-like bladed buzz saw located in its abdomen."


Godzilla on Monster Island

When Mothra's cocoon washed up on the island, Godzilla and Anguirus guarded it from their neighbors that were interested in destroying it. When Godzilla and Anguirus protected it from Gigan, a helicopter from the mainland ended up recording the battle, resulting in Mechagodzilla being dispatched to recover the cocoon for scientific study.

Who's Afraid of Godzilla?

Gigan was one of the monsters living on Monster Island. When Godzilla was tired of his fearsome reputation keeping him from making any friends, he decided to leave the island and search elsewhere. This left Gigan and Megalon as the strongest monsters on the island, and they bullied the other monsters in Godzilla's absence. Anguirus finally decided to take a stand against them and went to the peak of the island's volcano to fight them. However, the two monsters pushed Anguirus into the crater. Godzilla, returning to the island, frightened Gigan and Megalon away, allowing him to rescue Anguirus from the pit and gain the trust of the other monsters.

GODZILLA: Project Mechagodzilla

Gigan was discovered hibernating on the ocean floor off the coast of Siberia. A monster resembling a cross between an aquatic dinosaur and a bird of prey, Gigan possessed scales on his body and flight capabilities, and was characterized by a long claw on his forelimbs shaped like a sickle. He was captured by the United Earth and modified using Exif and Bilusaludo technology to be used as a weapon against Godzilla. Gigan was employed in "Operation: Long March," a plan by the United Earth to lure Godzilla deep into Eurasia. Godzilla and Gigan first battled in Suez, and although both of Gigan's arms were severed in the battle he succeeded in bringing Godzilla from Africa to Eurasia. Nonetheless, Gigan was salvaged and continually employed in "Operation: Long March," luring Godzilla deeper and deeper into Eurasia. In each subsequent battle in Baku, Ashgabat, Samarkand, and Kashgar, Godzilla progressively maimed Gigan more and more severely, only for his masters to replace his lost body parts with mechanical ones and gradually convert him into a cyborg. Gigan's hands were replaced with sickles and hyper-vibrating chainsaws, homing missile launchers were installed on his arms, his eyes were replaced with a single goggle-like visor, and his abdomen was equipped with a prototype blade launcher intended for use by Mechagodzilla. As Gigan repeatedly battled against Godzilla during "Operation: Long March," he was credited with saving the lives of many United Earth soldiers taking part in the operation and received a great deal of trust and respect among them. In a battle between the monsters in Yarkant, China, Godzilla damaged Gigan's wings, arms, and head, but in 2045 the Bilusaludo redeployed Gigan in Hotan and injected him with experimental Nanometal, which allowed him to instantaneously heal from grievous injuries. However, Godzilla eventually destroyed Gigan completely with an extremely powerful blast of atomic breath, leaving no trace of the monster behind. Michael N. Hunter, a United Earth medical officer who served in "Operation: Long March," came into possession of one of Gigan's scales and vowed to return it to Siberia as a gesture of gratitude and atonement for Gigan's suffering and sacrifice on behalf of mankind.[11]


Fun Kindergarten Zone Fighter manga

Gigan in a Zone Fighter manga

In the Zone Fighter manga adaptation published by Fun Kindergarten, Gigan appears under the control of the Garogas, as he does in the TV series. He battles Zone Fighter alongside fellow Terror-Beast Balgaras. Notably, Gigan uses his optic laser beam in this manga, one of the earliest known instances of Gigan using this ability in officially licensed media.

Cinema Shares' Godzilla vs. Megalon adaptation

In this promotional comic for the U.S. release of Godzilla vs. Megalon by Cinema Shares International, Gigan (called "Borodan") is said to have been "acquired" by Megalon, rather than being lent to the Seatopians by the M Space Hunter Nebula Aliens. Borodan fights both Godzilla and Jet Jaguar (called "Robotman"), but is defeated after he gets dropped from a great height by Robotman.

Godzilla, King of the Monsters

In this short manga series, Gigan is featured as an enemy of Godzilla who is under the control of Dr. Mad Oniyama, who had survived his apparent death after KIDS exploded by rebuilding much of his body with cybernetics. This Gigan was called Neo Gigan, and was sent to Earth from space with King Ghidorah III at the end of Volume 1. Interestingly, Oniyama had extensively modified Neo Gigan so that he was more of a mech than a cyborg, piloting Neo Gigan from inside his head.

After Ebirah implanted a mind control device on the side of Godzilla's head, Oniyama activated the device to put Godzilla under his control, having the King of the Monsters break out of the JSDF facility where he had been brought to after being frozen, then rampage through a city with Neo Gigan beside him. After Yosuke Kaneko managed to shoot off the device with missiles from his ASTOL-MB93, Godzilla turned his attention to Neo Gigan. Undeterred by this setback, Oniyama had Neo Gigan engage Godzilla in battle. With Godzilla still recovering from his fights against Ebirah and King Ghidorah III, he was unable to effectively handle Neo Gigan's attacks, and became ensnared by the cyborg's cables, then repeatedly shot with the Optic Laser. As Hideo Kaneko and Linda Miller agonized over how to provide Godzilla with the energy he needed to fight back, Yosuke came up with a plan. After shooting at Godzilla to attract the Monster King's attention, he ejected from his ASTOL-MB93, sending the aircraft directly into Godzilla's mouth and engulfing his head in an explosion. As the dust cleared, Godzilla stood strong, the energy from the aircraft and its arsenal having given him an all-important boost.

With the fight resumed, Godzilla quickly gained the upper hand after tensing up to break Neo Gigan's cables. Though Neo Gigan's hooks were now no longer usable, the cyborg had another trick up its sleeves, and began firing explosive Napalm Shells from the open appendages in an attempt to injure Godzilla. This had little effect beyond briefly stunning him, and Godzilla managed to force his way through the explosions to begin manhandling Neo Gigan up close. As the cyborg was forced to use his buzzsaw, Godzilla managed to pull off one of Neo Gigan's arms at the shoulder, exposing the cybernetics inside his chest. In a successful attempt to escape, Oniyama flew Neo Gigan's head away towards Satan Atoll to plan his final attack, with Neo Gigan's headless body self-destructing afterwards, though ultimately this did very little to injure Godzilla.

Despite Neo Gigan's destruction, Oniyama had succeeded in his secondary goal, and had obtained a sample of Godzilla's cells to grow into the clone that would eventually become King Godzilla.

Godzilla: Legends

As Anguirus prepared to face off against Destoroyah, Dr. Brian Anders recalled how every previous opponent Anguirus faced, such as Gigan, had defeated him in the past, and thus cast doubt over his odds of being able to defeat a monster such as Destoroyah.


Gigan in Godzilla #9

After being struck by lightning generated from Mothra's wings, Claire Plangman experienced a vision of space monsters who would soon invade the planet, Gigan among them. Not long after, the vision came to pass as Gigan, SpaceGodzilla, Hedorah, and Monster X arrived and invaded Earth. Landing in Hong Kong, Gigan used his abdominal buzzsaw and claws to decimate buildings while shrugging off everything the military threw at him. While rampaging, Gigan was suddenly attacked by Rodan, who slammed the cyborg into a building. Rodan was soon joined by Anguirus after the latter was freed from Monster Island, who rolled into Gigan to use his spiked carapace against him. However, the cyborg instead took the opportunity to grab Anguirus and sliced into the monster's stomach with his buzzsaw. Rodan rushed to help his fellow Earth defender, and though Gigan fired a laser at the winged monster to stop him, Rodan dodged the attack and used the spikes on his chest to shatter Gigan's eye visor and knock him to the ground. As Rodan prepared to engage Gigan once again, Gigan suddenly leapt into the air and grabbed Rodan, pulling him down to the Earth and using his buzzsaw to carve into Rodan's chest. While attacking Rodan, Gigan failed to notice that Anguirus had recovered until it was too late - after curling into a ball, Anguirus threw himself into Gigan's head with all his might, freeing Rodan and finally knocking Gigan out for good.

Godzilla: The Half-Century War

Attracted by Dr. Deverich's Psionic Transmitter following its activation in 1987, Gigan and King Ghidorah arrived on Earth and embarked on a tour of destruction the likes of which the world had never seen. By 2002, the duo reduced half the planet to cinders with nothing able to stop them. In a last-ditch effort to save the world, the Anti-Megalosaurus Force readied a new weapon called the Dimension Tide, which was capable of firing miniaturized black holes, and lured the space monsters to Antarctica using multiple Psionic Transmitters in the hopes of unleashing this new weapon upon them. As Gigan and King Ghidorah made landfall, Godzilla also arrived and confronted the duo. After dodging Godzilla's atomic breath, Gigan struck first, slicing Godzilla's neck and distracting him to allow King Ghidorah to restrain him. Just as Gigan prepared to launch another assault, he was struck by missiles launched from the AMF's new Mechagodzilla, piloted by Ota Murakami. Once King Ghidorah and Gigan turned their attention to the mech, Godzilla grabbed onto one of King Ghidorah's heads as he was attacking Mechagodzilla and made him accidentally knock Gigan out of the sky with his Gravity Beams. Godzilla then temporarily joined forces with Mechagodzilla, with both firing their respective beams at Gigan as he was attempting to get back up, which severed one of his arms. While King Ghidorah battled Godzilla, Ota realized the Dimension Tide was about to fire and rushed to grab the injured Gigan with Mechagodzilla so he would end up within the line of fire. After the miniaturized black hole was launched, Mechagodzilla released Gigan next to King Ghidorah just in time, allowing both alien monsters to be sucked in together and ending their threat to Earth.

Godzilla: Rulers of Earth

The upgraded Gigan in Godzilla: Rulers of Earth #6

Some time after his defeat in Hong Kong, the blinded and damaged Gigan erupted from the earth in Arizona's Grand Canyon, where he was being secretly observed by the Cryog aliens. Gigan soon discovered the nest of Kumonga, who promptly attacked by spitting webbing at the cyborg and pulling him down into the nest. Despite his efforts to escape, Kumonga wrapped Gigan within a cocoon, at which point Gigan faked defeat to allow Kumonga to get closer. Using his abdominal buzzsaw, Gigan severed one of Kumonga's legs and freed himself from the cocoon before using his eye laser to set the whole valley on fire. After Gigan escaped, the Cryog noted that their cyborg was in need of an upgrade and summoned him to their ship.

Now under Cryog control, the rebuilt and upgraded Gigan was sent to Area 51 in Nevada in order to recover the Millennian UFO. Gigan escorted the UFO to Las Vegas, where he was confronted by Godzilla. In retaliation for being struck by Godzilla's atomic breath, Gigan launched his grappling hooks around Godzilla and proceeded to drag him across the city, allowing the UFO to begin absorbing the temporarily incapacitated Godzilla's DNA. The Counter-Kaiju Reaction Forces deployed their new mech, MOGUERA, to attack Gigan. Though Gigan used his laser to destroy the missiles launched at him, MOGUERA proved a formidable opponent for Gigan, blocking his attacks while using its lasers and drills to place the cyborg on the defensive. After MOGUERA tackled Gigan to the ground, the mech turned its attention on the UFO, allowing Gigan to recover and attempt retaliation. However, MOGUERA dodged the attack, causing Gigan to accidentally destroy the UFO instead and release the newly-formed Orga. While Godzilla engaged Orga, Gigan assisted his new ally by wrapping his grappling hooks around Godzilla again, though the King of the Monsters was able to free himself and use the cables to drag Gigan towards him. Amid the chaos, Orga went berserk and suddenly grabbed Gigan in an attempt to eat him. Gigan ultimately freed himself from the beast's maw by impaling him through the head with his scythe hand and using his buzzsaw to chop off Orga's fingers. Godzilla then grabbed Gigan by the tail and slammed him into the ground. Soon after, Orga was blown to pieces after swallowing Jet Jaguar, who grew to gigantic size from within the monster's stomach. Godzilla temporarily joined forces with this new combatant against the now-outnumbered Gigan, who struggled to defend himself as Godzilla and Jet Jaguar pummeled him into submission. After ripping off part of Gigan's tail and cracking his visor, Jet Jaguar left to destroy Orga's regenerating remains, finally allowing Gigan to retaliate. Burning Godzilla with his laser, Gigan slashed Godzilla's chest with his claws until Star Falcon distracted Gigan long enough for Godzilla to regain the upper hand. Gigan stabbed Godzilla in the foot, but Godzilla was able to hold the cyborg down and struck him with a point-blank blast of his atomic breath, burning the cyborg. Too injured to continue fighting, Gigan retreated alongside a Cryog ship containing Orga's regenerating remains.

Years later, the Cryog used the repaired Gigan to sever King Ghidorah's center head so they could outfit the monster with mechanical enhancements. Following Mecha-King Ghidorah's defeat, the Cryog were forced to deploy Gigan again to defend their ship when it came under attack by the cyborg's former ally, SpaceGodzilla. Though Gigan was unable to land a hit with his laser, the cyborg deployed his grappling hooks around SpaceGodzilla's tail in an attempt to pull him away from the Cryog ship. However, SpaceGodzilla was able to use his telekinetic powers to encase Gigan within a prison of crystals, temporarily incapacitating the cyborg until Gigan used his buzzsaw to free himself. Gigan used his buzzsaw to slash SpaceGodzilla's chest and damaged one of his shoulder crystals, though SpaceGodzilla retaliated with his Corona Beam and burned the sails on Gigan's back. Gigan's right arm became caught in SpaceGodzilla's crystalline hide after the latter took on his flying form, forcing Gigan to sever it in order to escape. In the aftermath, the Cryog rescued Gigan and upgraded him once more, this time with double chainsaws on each arm, and concealed him within Earth’s Moon.

When the Cryog Emperor Karkaro arrived to take revenge against his underling Rhizon for his insubordination, he destroyed Rhizon's ship, inadvertently releasing Gigan against his own army. Gigan proceeded to attack and wipe out all of Karkaro's fleet, employing his chainsaws to cut some in half while utilizing his speed to avoid the ships’ defense mechanisms and cause them to fire upon each other. Sensing Gigan, Jet Jaguar flew up to the ships to confront the Cryog’s cyborg once more, kicking Gigan and fighting him atop Karkaro’s ship. Gigan was able to cut into Jet Jaguar’s side, but the robot then grabbed Gigan and forced him to cut into Karkaro's ship with his chainsaws, crippling the spacecraft. After a brief argument, Rhizon shoved Karkaro into Gigan's still-active chainsaw blades, killing him, before the entire ship crashed into Magita, the giant Trilopod. Gigan disappeared following the destruction of the ship, but evidently managed to survive; he was later being repaired in an unidentified location alongside a single Mechagodzilla unit, possibly by surviving Cryogs.

Godzilla: Rage Across Time

During the 13th century, Gigan and Megalon fell under the control of Zhenjin Khan, the Dragon-Master, and were sent to obliterate Japan alongside the Mongolian troops, who were actually the Nebulans in disguise. As the warriors of Japan fought back against the Mongolians, the two monsters laid waste to the land, destroying everything in their path. Just when it looked like all hope was lost, Godzilla arrived to challenge the monsters after being lured to the scene by a pair of brave warriors. After stopping Megalon's napalm bomb attack, Godzilla took on Gigan, who leapt into the air and flew over Godzilla in efforts to slice into the King of the Monsters with his abdominal buzzsaw. After dodging the attack and knocking Gigan down with his tail, Godzilla grabbed onto Gigan and used him as a shield against Megalon, who accidentally struck Gigan with his laser beam instead. Upon freeing himself, Gigan retaliated with his laser beam, which began to turn the tide back in the duo's favor. Soon, Godzilla was overwhelmed by his enemies' coordinated teamwork, with both unleashing their respective beams on him before Gigan restrained him so Megalon could drill into Godzilla's chest. When it seemed like Godzilla would be defeated, the Mongol relic that controlled Gigan and Megalon was destroyed by a fire arrow shot from Akio, the infamous woman warrior. Freed from outside influence, the dazed and confused kaiju allowed Godzilla to regain control of the battle, blasting Gigan with his atomic breath and swatting Megalon away. With that, both kaiju decided to retreat and flew off into space while Godzilla destroyed the remainder of the invading army, saving Japan.

Godzilla vs. The Mighty Morphin Power Rangers

Gigan challenges the Megazord in Godzilla vs. The Mighty Morphin Power Rangers

After the Power Rangers subdued Godzilla with the Megazord and boarded the Xilien mothership, the Xiliens moved to the penultimate stage of their invasion plans by sending Gigan to Earth. As Gigan ravaged an amusement park where survivors of the Xilien assault had sought refuge, the Power Rangers realized they needed to intervene and summoned their Dinozords. The Rangers attempted to fight Gigan in the individual Dinozords to no avail, as Gigan shrugged off their beam attacks with ease, thus leading them to combine into the Megazord. However, the Megazord was still damaged following a recent battle with Godzilla, prompting Rita Repulsa to press her advantage by summoning Rhinoblaster and Eye Guy to Gigan's side after Gigan further damaged the mech with his abdominal buzzsaw and lasers. Gigan slashed and stomped on the Megazord with his new allies, but was finally knocked back by the Megazord's Cranial Laser and a swift kick. After recovering, Gigan attempted to attack the Megazord from behind, only to be struck by Godzilla's atomic ray as the King of the Monsters returned. Godzilla was quick to engage the trio of monsters as well as the Megazord, grappling with all of them and swatting Gigan with his tail until he began to tire, at which point the three monsters assaulted Godzilla at once with their respective beam attacks. Realizing they needed Godzilla's aid, the Megazord summoned the Power Sword to heal Godzilla's previous wounds, at which point he began working alongside the mech. The duo were quick to unleash their fury upon Gigan and Rita's monsters with the Megazord's Cranial Laser and Godzilla's atomic breath, injuring them further. After Godzilla and the Megazord defeated Rhinoblaster and Eye Guy, the wounded Gigan retreated and escaped with his life.

Godzilla Rivals: Vs. Gigan

Gigan brutally attacks Godzilla in Godzilla Rivals: Vs. Gigan

In 2008, the Nebulans unleashed Gigan in Seattle, Washington, where the cyborg proceeded to destroy the USS Nimitz and anything the military threw at him. Before Gigan could reach the city, Godzilla appeared and confronted him in the waters outside of Seattle as the Nebulan leader broadcast his message to the world, proclaiming that Gigan would defeat Godzilla and allow his race to take over the planet. Gigan initiated the battle by levitating into the air and launching his Bladed Slicer disks at Godzilla, which Godzilla managed to avoid before leaping at Gigan, grabbing his leg, and throwing him back into the water by the wreckage of the Nimitz. Gigan then used the Nimitz as a shield against Godzilla's atomic breath before unleashing his eye laser on Godzilla, forcing the King of the Monsters back. As Gigan continued his assault, Godzilla grabbed a large rock underwater and bashed it against Gigan's head to shake him off. Gigan retaliated by slashing Godzilla's shoulder and delivering a flying kick to his head. Just as Godzilla recovered, Gigan fired his grappling hooks at him, embedding them in Godzilla's shoulder and using them to pull Godzilla up into the air. Before he could land, Gigan slashed into Godzilla's throat, severely wounding him. Teenager Joaquin then recognized Gigan’s moves from a video game made by Hexapod Games, which his sister Nancy later discovered to be a front for the Nebulans. It turned out that the Nebulans used the data collected from millions of players online and uploaded it directly into their cyborg monstrosity, making Gigan unstoppable. As the battle continued, Gigan continued to slash into Godzilla's skin and later unleashed another blast of his eye laser on his opponent. After the Nebulan leader discovered Nancy hacking into Hexapod's servers, he ordered Gigan to kill Godzilla immediately. Gigan proceeded to lift Godzilla and throw him down before slashing into his throat once more, but before he could deliver a killing blow, Nancy was able to sever the data being fed into Gigan's central processing unit. With Gigan offline, Godzilla took advantage of the stalled cyborg and forcibly ripped Gigan's left arm off with his mouth. As the Nebulans desperately attempted to regain control over their creation, Gigan's animal mind proved to be no match for Godzilla, lacking all the strategies and tactics that the Nebulans previously gave to him. Using Gigan's severed arm, Godzilla stabbed Gigan through the neck before grabbing Gigan's head and crushing it in his hands, ending Gigan's threat for good as his body fell back into the water.

Godzilla Rivals: Vs. Mechagodzilla

By the year 2074, giant monster attacks were occurring around the world on a daily basis, with kaiju such as Gigan being responsible for untold destruction. Following Mechagodzilla’s defeat at the hands of Godzilla, it was revealed that Gigan and King Ghidorah were secretly pawns of the Xiliens, who were preparing to send the two kaiju back to Earth once they had seized the mech for themselves with the intention of using it to aid their invasion efforts.

Godzilla Rivals: Jet Jaguar Vs. Megalon

While speaking with Jen Onça, Jet Jaguar revealed that he was created to protect humanity from giant monsters, with Gigan being among the robot's past opponents.

In Zone Fighter, Gigan was played by Isao Zushi, who also played Godzilla in Godzilla vs. Mechagodzilla.
  • In Godzilla Island, Gigan is the only space kaiju to ally himself with Godzilla.
  • Gigan shares some physical similarities with the Ultraman kaiju Dorako, most prominently his hooked forearms, along with a pointed beak-like face and large sail-like structures on his back, although in Dorako's case these are styled after the wings of a dragonfly.
  • Gigan's ability to fire off shurikens in Godzilla Final Wars is very similar to Guiron's secondary attack, where he can fire four shurikens from indents in the side of his head.
  • In Godzilla: Rulers of Earth, Gigan appears in his Showa design in issue #1 and is later upgraded to his Millennium design in issue #5, and later into Modified Gigan. This is the first time Gigan is upgraded from his Showa design to his Millennium design visibly, though Gigan's bio from the instruction manual of Godzilla: Unleashed states he was upgraded using the "latest Vortaak technology," referencing the use of Gigan's Showa design in the previous two Atari/Pipeworks games.
  • The Ultraman Ace choju Chameleking has a saw in his stomach like Gigan, though it is never used in combat.
  • Gigan's head makes a brief appearance in Pacific Rim Uprising, during the scene where Hermann Gottlieb examines PPDC records in search of a match for the image Mako Mori transmitted.
  • The Showa Gigan is tied with King Ghidorah for the fastest-moving Showa Godzilla kaiju and the second fastest overall, travelling at speeds of up to Mach 400 when outside the Earth's atmosphere. They are surpassed only by SpaceGodzilla, who approaches light speeds when in his Flying Form.
  • Gigan is featured in concept art published in The Art of Godzilla: King of the Monsters which depicts the film's final scene.[35] In an interview with the Los Angeles Times, director Michael Dougherty said, "We had thought about using some additional Toho creatures to give them some cameos but every Toho creature comes with a price tag. It was a choice to either shell out more money simply for the rights for these creatures to show up on screen for a few seconds, or embrace the opportunity and the challenge to create new creatures."[36]
  • The 2016 book Godzilla Against Type-3 Kiryu (Mechagodzilla) Completion adds Gigan to the Kiryu series continuity, with Type 66 Maser Cannons fending him off in 1972.
  • In a 1996 special Children's Day stage show, Gigan was summoned to attack the Earth alongside the Space Bosozoku Bowzock, General Jark, Shocker, Bemstar, Alien Baltan, Alien Pitt, and Alien Bado. The effort was thwarted by the combined forces of Kamen Rider, Kamen Rider J, Kamen Rider Black, the Carrangers, Ultraman, Ultraseven, Ultraman Taro, and Godzilla.
  • The design of the monster Kamanga in the 2021 anime Godzilla Singular Point was influenced by Gigan.
  • Gigan is the first cyborg monster in the Godzilla series, predating Mecha-King Ghidorah and Kiryu.

  1. Gigan's designer was widely disputed prior to the mid-2000s, often confused for mangaka Shigeru Mizuki due to his being a Kodansha artist named "Mizuki," or Akihiko Iguchi, who publicly denied having any involvement with the film.
  2. If King Ghidorah is a dignified villain, then Mechagodzilla has the image of a nihilistic killer. Gigan has a similar image of a killer but his image of a bloodthirsty, ferocious cutthroat serves as contrast, as Mechagodzilla has a strong image of a consistently coldhearted and composed professional. This is because Mechagodzilla is a literal mecha, so its true feelings are unable to be seen. Thus is the charm of Mechagodzilla. / キングギドラを威厳に満ちた大悪役とするならば、メカゴジラはニヒルな殺し屋というイメージがある。同じく殺し屋のイメージを持つガイガンが血に飢えた凶暴な殺人鬼のイメージなのに対して、メカゴジラはあくまでも冷たく冷静なプロフェッショナルのイメージが強い。これはメカゴジラが文字通りメカであり、感情がまったく見えないからであろう。そこがメカゴジラの魅力になっているのだ。
