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.


Mecha-King Ghidorah's roar is mechanical in nature.


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 throughout 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 and is 1 foot tall 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.

Gravity beams

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.

Laser Triple Beam

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.


In the GBA video game Godzilla: Domination!, Mecha-King Ghidorah could spit orange fireballs from its left and right heads and green fireballs from its central head.

Energy Orbs

In the GBA video game Godzilla: Domination!, Mecha-King Ghidorah could spit energy spheres from its central head. they are blue and red in color. once its left and right heads are destroyed, the central head fires them erratically.


In the Atari/Pipeworks trilogy of Godzilla video games, Mecha-King Ghidorah could launch tasers from the aperture on his torso, which can incapacitate opponents and drain their energy.

Video games

Godzilla (Arcade)

Mecha-King Ghidorah appeared within the Arcade Godzilla game.

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: Trading Battle

Mecha-King Ghidorah appeared within Godzilla: Trading Battle.

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

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.

Godzilla Unleashed: Double Smash

Mecha-King Ghidorah also appears within the similarly named title Godzilla Unleashed: Double Smash.

Godzilla (2014 video game)

An artificial version of King Ghidorah that was defeated by Godzilla, remaining in suspended animation under the sea in Hokkaido for 212 years before being revived by the 23rd-century Earth Union Organization (EUO), Mechanics remodeled its central neck, wings, body, and legs, turning it into a powerfully armed cyborg monster. The Futurians had planned to crush Japan, which was on the cusp of becoming a world superpower two hundred years later. Using time travel, the Futurians attempted to return to the past and dispose of Mecha-King Ghidorah's natural enemy, Godzilla.

When Mecha-King Ghidorah made its first appearance, it fought with Godzilla in front of the newly completed Tokyo Metropolitan Government building. Because the full-body costume weighed some 200 kilograms (440 lbs.), the production team took safety into consideration and operated it without a stuntman inside the costume during filming.

Godzilla: Rulers of Earth

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.

  • The scene in which Mecha-King Ghidorah appears over Tokyo for the first time is a direct reference to his very first appearance in Ghidorah, the Three-Headed Monster, where he materializes in midair in a flash of light.
  • While Ghidorah's two side heads are perfectly intact, they seem to have no independent will apart from the mechanical middle head operated by Emmy, as seen as when Emmy fires the robotic head's laser beam and the two organic ones automatically start shooting their gravity beams as well.
  • Mecha-King Ghidorah and the Heisei King Ghidorah are the tallest main series Godzilla monsters.
  • The Kaiju Guide from the 2014 Godzilla game 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 utilized 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. He also appears to be fully controlled by Emmy, and is possibly in a comatose state without a will of its own.
  • An unused sound byte exists in the PlayStation 3 version of 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.

  • A similar character named MechaGhidorah was designed at one point. This 100 meters tall and 60,000 tonnes character had a background and abilities similar to that of Daiei's Wyvern; a bio-mechanical kaiju designed by an outer space race to defeat monsters on Earth, and each head possessed different beam ability including a gravity beam, ice beam, and heat ray.
