Mecha-King Ghidorah (メカキングギドラ,   Meka Kingu Gidora?) is a mechanically modified Ghidorah created by Toho that first appeared in the 1991 Godzilla film, Godzilla vs. King Ghidorah.


Mecha-King Ghidorah's name is simply a combination of the word "mecha," which means a robot that can be controlled from inside it, and King Ghidorah.


Mecha-King Ghidorah has a futuristic and mechanical look, with his middle head mechanized as well as his wings, torso and a few other areas. He's considerably more powerful than the purely organic King Ghidorah.

In Godzilla Island, Mecha-King Ghidorah has three mechanical heads instead of one, and also has no gold coloring anywhere on his wings.

Godzilla vs. King Ghidorah

Mecha-King Ghidorah in Godzilla vs. King Ghidorah

After defeating King Ghidorah and sending it to the depths of the sea, Godzilla began to wreck havoc throughout Japan. Emmy Kano, a Futurian who rebelled against her crew, and M11, her android, were asked if King Ghidorah could be revived in the 23rd century. If possible, he could be brought back to the present and used as an anti-Godzilla weapon to protect Japan. Emmy and M11 agreed and went to the future using the time machine KIDS.

As Godzilla continued his rampage through the center of Tokyo, King Ghidorah, now Mecha-King Ghidorah, materialized in a flash of pulsing energy. Piloted by Emmy and reinforced with several robotic segments, Mecha-King Ghidorah was more powerful than before. Mecha-King Ghidorah fired his gravity beams and triple laser beam at Godzilla, sending him crashing toward some buildings. Godzilla managed to regain his balance and damage both of Mecha-King Ghidorah's wings. Emmy then fired Mecha-King Ghidorah's energy-conducting capture cables and released its machine hand restraint. Mecha-King Ghidorah lifted Godzilla into the sky and over the sea, but both were sent crashing into the waves when Godzilla fired his atomic breath at it. Emmy quickly escaped in KIDS, leaving both monsters trapped on the ocean floor. At first, it seemed as if M11's circuitry was still onboard the cyborg, but it turned out that he had been hastily rescued by Emmy before escaping in KIDS.

Meanwhile, beneath the surface of the sea, Godzilla fired his atomic breath and freed himself from Mecha-King Ghidorah's grasp and left it behind, retreating to the ocean.

Godzilla Island

Mecha-King Ghidorah in Godzilla Island
After facing yet another defeat at the hands of the inhabitants of Godzilla Island, the evil Xilien Zaguresu immediately realized it would take noting short of a miracle if her plans for planetary conquest were to succeed. Luckily for her, that miracle soon arrived in the form of a giant object, the Monster Vending Machine, that gave her the choice of purchasing a monster. Her choice: Mecha-King Ghidorah, a cybernetic monster that she hoped would assist her in her invasion. She then sent the monster down to Godzilla Island, where it landed in front of Godzilla. However, several moments passed, and Mecha-King Ghidorah did not move. Soon it became apparent to Zaguresu what must have happened: Mecha-King Ghidorah did not have a pilot, and would not work without either a pilot or modifications allowing it to work on its own. Godzilla then ventured forward and simply knocked the cyborg over, and very soon the G-Guard Commander and Torema formulated a plan: use the robot to attack Zaguresu's ship, the Vabaruda, in a full-frontal assault. The Commander soon took off in Mecha-King Ghidorah and Torema followed in her smaller ship, and the two attacked Zaguresu. For some time, the plan worked, but unfortunately a rogue asteroid knocked both the Commander and Torema back towards Earth. Using a tractor beam, Zaguresu brought Mecha-King Ghidorah back to her ship and soon flew it down personally to attack Godzilla Island. Fortunately, the monsters led an attack of their own, and soon drove the robot back into space.

Mecha-King Ghidorah would be called on again by Zaguresu to attack Godzilla Island, but each time the beast would be forced to flee. Soon, her leader, the Giant Dark Emperor, began to tire of her constant losses and Zaguresu was finally driven from Earth by Torema and was never to be seen again until Story 22 (Final Battle: Mecha-King Ghidorah Saga). Eventually, a more powerful version of Mecha-King Ghidorah called Hyper Mecha-King Ghidorah was purchased from the giant vending machine by Zaguresu and sent to attack Godzilla Island.


  • Mecha-King Ghidorah flies with Anti-gravity at the speed of mach 4.
  • Mecha-King Ghidorah can fire yellow Gravity beams from its mouths on the left and right head since it was a modified version of King Ghidorah.
  • Mecha-King Ghidorah can fire a Laser Triple beam from the central head. In Godzilla Island, however, all three heads can fire Laser Triple beams, due to having three mechanical heads as opposed to one like in Godzilla vs. King Ghidorah.
  • Mecha-King Ghidorah is equipped with Capture Cables and a large Machine Hand restraint that can also discharge electricity.


Video Games

Super Godzilla

Mecha-King Ghidorah appears as the penultimate boss in the 1993 video game Super Godzilla for the Super Nintendo Entertainment System. In this game, Mecha-King Ghidorah is the result of alien invaders cybernetically reviving King Ghidorah following his earlier battle with Godzilla and sending him back into battle. Mecha-King Ghidorah can be fought with either Godzilla or his more powerful form, Super Godzilla.

Godzilla: Domination!

Mecha-King Ghidorah appears as the unplayable final boss in Godzilla: Domination!, where he is fought on the final stage, Meteor X. In this game, Mecha-King Ghidorah is significantly enlarged, standing several times taller than the playable monsters and taking up nearly half of the stage. Mecha-King Ghidorah doesn't move around, but will occasionally jump, damaging the player unless he or she jumps as well. The only way to damage Mecha-King Ghidorah is to hit his robotic head, then hit the flashing point on his body after he is stunned. Mecha-King Ghidorah mostly attacks by breathing fireballs or firing energy blasts. When he takes enough damage, one of his organic heads will die and vanish, which results in health and energy power-ups being spawned. After Mecha-King Ghidorah is damaged enough, his second organic head will be destroyed, leaving only his robotic head. Mecha-King Ghidorah's robotic head will move incredibly quickly, making it difficult to hit, while using an attack that launches a spread of fireballs. When Mecha-King Ghidorah is finally defeated, his robotic head will explode, followed by his entire body, engulfing the screen in a white flash.

Godzilla: Destroy All Monsters Melee

Mecha-King Ghidorah appears as a playable character in Godzilla: Destroy All Monsters Melee. If the player uses Mechagodzilla 2 in story mode, Mecha-King Ghidorah takes his place as the final boss.

Godzilla: Save the Earth

Mecha-King Ghidorah returns in Godzilla: Save the Earth. He plays similar to King Ghidorah, meaning he is powerful, slow, can fly, has a large amount of health, and has most of the some moves with some changes and different resistances. He does have two extra abilities, however. The first is that he has a taser attack that, if it connects, paralyzes his opponent and quickly drains away their energy. The taser can only be used three times, but collecting energy power-ups allows it to be used again. The other is that his block is an energy shield, which uses energy, and will absorb a weapon attack and convert it into his own health. Although he had the same rage attack as King Ghidorah in Destroy All Monster Melee (flying into the air while spinning around firing all three gravity beams), in Godzilla Save the Earth he now becomes temporarily invincible and any opponent that touches him is knocked away.

Godzilla: Unleashed

Height: 120 meters
Weight: 80,000 tons

"Mecha-King Ghidorah is the GDF's best attempts to use the weapons of the Vortaak to defend Earth, rather than destroy it. After King Ghidorah's defeat at the hands of an Earth Defender in one possible future, the alien monster was rebuilt with GDF technology to serve the interest of mankind. To replace King Ghidorah's natural body armor, destroyed in the re-animation process, this new incarnation has been outfitted with a powerful energy shield to reflect weapon attacks. In addition, Mecha-King Ghidorah has replenishable taser weapons, which can drain an opponent's energy reserves. With most of his original form's combat techniques intact, Mecha-King Ghidorah might stand as humanity's best hope against the Vortaak invasion."

Bandai Namco's Godzilla

Mecha-King Ghidorah appears as a playable monster exclusively in the PlayStation 4 version of the game. Mecha-King Ghidorah has the ability to fly and fire gravity beams like King Ghidorah, but also possesses the Machine Hand from the film. When playing as Mecha-King Ghidorah in God of Destruction Mode, the player will need to defend cities from attacking kaiju, and prevent a certain percentage of the city from being destroyed.

Godzilla: Rulers of Earth

Mecha-King Ghidorah in Godzilla: Rulers of Earth #16
Mecha-King Ghidorah makes his first appearance in the IDW Godzilla comics in issue #15 of Godzilla: Rulers of Earth. After Godzilla survives an onslaught of Mechagodzillas, Mecha-King Ghidorah flies above him and abducts him with his capture cables and machine hand. Mecha-King Ghidorah, who is being telepathically controlled by the psychic twins Minnette and Malorie working for the Cryog leader, is ordered to take Godzilla to a robotics facility in Russia, which the Cryog leader has converted into a battle arena. Ghidorah drops Godzilla in the arena, where other Mechagodzillas are waiting. While the alien robots begin to overwhelm Godzilla, Anguirus escapes from the downed Kiryu's grip and enters the arena to help Godzilla. As the battle progresses, the twins note that either they are losing control over Mecha-King Ghidorah, or they never had it in the first place. After Godzilla destroys the Mechagodzillas and Ghidorah's control module, the twins are knocked out from the shock and Ghidorah flies away under his own power. After this, Mecha-King Ghidorah disappears from the comic's storyline, and he is never shown interacting with the Trilopods in any way, nor do the Cryogs ever attempt to retrieve him.

Godzilla: Oblivion

In the fourth issue of Godzilla: Oblivion, Mecha-King Ghidorah was constructed by a group of humans using the corpse of King Ghidorah in order to fight Godzilla and draw him back to his home dimension. After destroying the army of Kiryus sent to attack him, Godzilla arrived at the humans' research facility, where the recently-completed Mecha-King Ghidorah was activated and attacked him.

Mecha-King Ghidorah's roars


  • Mecha-King Ghidorah and the Heisei King Ghidorah are the tallest main series Godzilla monsters.
  • Although the severely-wounded King Ghidorah was described as being just barely alive when the Futurians found it, Mecha-King Ghidorah requires a human pilot to act, implying it is alive, but otherwise braindead.
    • This suggests that King Ghidorah's central head is dominant over the others, although all three can think for themselves. This is demonstrated when the robotic head fires its laser beam, the other biological heads fire their gravity beams alongside it automatically.
      • This is further suggested in Godzilla: Rulers of Earth when the Cryog leader Rhizon has King Ghidorah's middle head cut off and replaced with a mechanical head so that he can control him.
  • The Kaiju Guide from Bandai Namco's Godzilla incorrectly states that Mecha-King Ghidorah was still under the control of the Earth Union Organization, when in fact he was being piloted by Emmy Kano and M11, who were both defectors from the Futurian terrorists.
  • Mecha-King Ghidorah is the first example of a 'good' Ghidorah, as he was utilised by Emmy so that she could defend Japan. However, this doesn't necessarily mean that he is 'good' by nature, as he was simply under the control of a Futurian.
  • An unused sound byte exists in the PlayStation 3 version of Bandai Namco's Godzilla of the G-Force operator saying Mecha-King Ghidorah's name, suggesting that he was supposed to appear but ended up being scrapped for unknown reasons. Nonetheless, Mecha-King Ghidorah was later confirmed to appear in the PlayStation 4 version of the game.
  • On the page for Godzilla vs. King Ghidorah on Toho's official website for the Godzilla series,, Mecha-King Ghidorah's Japanese name is misspelled as "Mega-King Ghidorah" (メガキングギドラ,   Mega Kingu Gidora?).[2]
  • Mecha-King Ghidorah's roar was used for a space dragon in Kaizoku Sentai Gokaiger.
