MechaGodzilla 1 was created as a weapon of destruction by a race of ape-like aliens. The rebel Weekees managed to control it, and used in once in Battle World, where it was destroyed, but deployed it in the sequel Tintin in Tokyo. It was damaged by the Iron Giant, and Mothra followed it. 


MechaGodzilla 1 has armor constructed out of a mysterious alloy known as "Space Titanium," which actually proved to not be particularly durable, as a brief fight with Godzilla caused enough damage for it to need to be called back for repairs. It is also equipped with a staggering amount of firepower.

MechaGodzilla is capable of firing a rainbow colored optical laser that seems to be equal in power to Godzilla's atomic breath- its head can rotate 360 degrees, allowing the robotic dinosaur to shoot down an opponent that might attempt to approach from behind. Spinning its head at high speed allows MechaGodzilla to raise a forcefield. When disguised as Godzilla, MechaGodzilla could fire a heat ray from its mouth. Curiously, after the disguise was destroyed, MechaGodzilla never used the heat ray again. When MechaGodzilla had its head removed in Terror of MechaGodzilla by Godzilla, it could fire a small concentrated beam from a small antenna.

MechaGodzilla 1 is also equipped with powerful missiles in its fingers, knees, mouth, and even its toes. These missiles can explode on contact with a target, or they may lodge in the flesh of an enemy like darts. Located under a hatch in MechaGodzilla's chest is a weapon that fires a jagged orange energy beam with enough slicing power to cut a mountain in half. Showa MechaGodzilla is no slouch in close combat either, as evidenced in its combat against King Caesar, though it couldn't beat Godzilla in this area. Finally, MechaGodzilla can fly via rockets in its feet able to reach a speed of Mach 5.
