Mechagodzilla (GvMGII)

The Heisei Mechagodzilla was created by the United Nations Godzilla Countermeasures Center (UNGCC) using Futurian technology scavenged from the remains of Mecha-King Ghidorah in Godzilla vs. Mechagodzilla II. Mechagodzilla's main purpose was to kill the King of the Monsters.

Godzilla vs. Mechagodzilla II
When Godzilla attacked the city of Kyoto, Mechagodzilla was deployed against him. The mechanical kaiju acquitted itself well, but was eventually defeated due to a voltage back-surge during their electrocution of Godzilla. One of Mechagodzilla's back-up pilots, Kazuma Aoki, suggested merging Mechagodzilla with a previous anti-Godzilla weapon. Namely, the airship Garuda, originally deemed a design failure and shelved in preference to Mechagodzilla.

Kazuma, in fact the chief designer and main pilot of Garuda to start with, found some personal redemption as his idea is approved. The combined form of the two mechs, dubbed Super Mechagodzilla, is unleashed against the King of the Monsters and Fire Rodan. In the heat of battle, Kazuma personally detaches Garuda and flies against Fire Rodan while the other Mechagodzilla crew continue against Godzilla. Kazuma is defeated, but manages to reattach the Garuda to Mechagodzilla to form Super Mechagodzilla. Super Mechagodzilla proceeds to destroy Godzilla's own reptilian secondary brain and moves in for the kill. Fire Rodan reappears, but is killed by a blast from Super Mechagodzilla. Upon dying, Fire Rodan's body dissolves, releasing the radioactive energy within its body and healing Godzilla's injuries. When Godzilla rises, its level of radioactivity is so high that Super Mechagodzilla's artificial diamond coating, which allowed it to deflect Godzilla's atomic breath, begins to melt. As a result, Super Mechagodzilla is rendered defenseless against the revived monster. Godzilla, temporarily supercharged with radiation, destroys the mech with a blood-red version of his atomic beam. Super Mechagodzilla's crew escape uninjured.

Arsenal
Heisei Mechagodzilla is protected by an armor plating made from an alloy called NT-1, which is coated in a layer of artificial diamond. The coating allows it to absorb energy from energy weapons such as Godzilla's atomic breath, which is then transferred to its ultimate weapon, the devastating Plasma Grenade, which is located on its waist. Mechagodzilla was also able to absorb energy from Rodan's heat beam and Heisei Mechagodzilla also possesses laser cannons in its eyes and a mega-buster ray from it's mouth. The megabuster in particular appears to be as powerfula s Godzilla's own atomic ray. It can fire tranquilizer missiles from its hips, paralysis missiles from the shoulders, and shock anchor cables from its wrists, enabling the robot to deliver powerful electrical charges in a struck opponent - this was later modified into a weapon called the "G-Crusher". Mechagodzilla's armor is nearly invincible, able to take a superpowered Godzilla's spiral breath repeatedly before finally going out of comission.

Finally, Mechagodzilla can attach to the warship Garuda. Upon doing so it gains Garuda's powerful maser cannons as well as the ability to hover above the ground by using Garuda's massive engines to achieve lift. This version is known as "Super Mechagodzilla". Super Mechagodzilla is one of Godzilla's most powerful advesaries, defeating both the King and Rodan, and came closer to killing Godzilla than any of Godzilla's other advesaries.

Video Game Appearances
The Heisei Mechagodzilla appeared in the video games Super Godzilla for the Super Famicon, Godzilla: Domination! for Game Boy Advance, Godzilla: Save the Earth for Microsoft Xbox and Sony PlayStation 2 and Godzilla: Destroy All Monsters Melee for Xbox and Nintendo GameCube.He also makes an appearance in Godzilla: Unleashed for PS2 and Wii. A version of MechaGodzilla also appears in Godzilla Unleashed: Double Smash for DS.

Heisei Mechagodzilla was removed from the English version of Super Godzilla in favor for the more-known Shōwa Mechagodzilla. This was due to the fact that at the time of the game's release, the new Godzilla vs. MechaGodzilla film had not been released on American shores.

Super MechaGodzilla was planned for Godzilla: Save the Earth, but because he mixed Kiryu's moves with MechaGodzilla 2's, he was cut from the game.

In Godzilla: Unleashed, Heisei Mechagodzilla is partially a clone of Mechagodzilla, though trading one cell of defense for one cell of speed. The only major differences between Mechagodzilla and Mechagodzilla 2 is the the latter can hover, fire his Plasma Cannon and use his jets to push away opponents like (Mecha)King Ghidorah uses his wings aside from flying. In this game, he is the only monster who can knock out a health cell with his beam, alongside the Showa MechaGodzilla.

In the Game Boy Advance video game Godzilla: Domination, the anti-Godzilla weapon Mechagodzilla II has the ability to unleash a flame from his hand in a slow attack with good reach. He also can perform a hydraulic kick, where he unleashes a flame from the jets on his feet for a slow attack with excellent reach. He can also do a claw launch, in which he fires off his fist, which will fly forward and then turn around and return to Mechagodzilla. A devastating attack with the potential to hit twice. His other video game abilities include the power to fire an electric bolt and the ability to create a cooling steam which will slightly heal Mechagodzilla and injure nearby monsters.

Godzilla Unleashed Bio for Mechagodzilla 2

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