Mechagodzilla
Mechagodzilla (メカゴジラ, Mekagojira) is the designated name of three separate mecha that appeared in the Toho's Godzilla film series. The character first appeared in the 1974 film Godzilla vs. Mechagodzilla as an extraterrestrial villain opposing Godzilla. In subsequent iterations, Mechagodzilla is depicted as a man-made weapon designed to defend Japan from Godzilla. In all incarnations, Mechagodziila appears as a robotic doppelgänger and arch-enemy of Godzilla.
Overview
Showa
The original Mechagodzilla was created as a weapon of destruction by the Simians, and the only one to be referred to by numerics within the movies themselves. First appearing in a pseudo-flesh outer covering and masquerading as the real Godzilla, Mechagodzilla begins a few attacks against Japan. Mechagodzilla then overpowers Godzilla's ally Anguirus and forces him to flee, but in the process damages his disguise. Godzilla then appears from a warehouse and destroys the pseudo-flesh disguise, forcing Mechagodzilla to reveal itself in full. Their initial battle resulted in a tie as Godzilla was severely wounded and Mechagodzilla was forced back into the Simian's base for repair. Fearing the robot's advance, a priestess of the Azumi royal family awakened King Caesar, an ancient Okinawan deity. Despite the shisa golem's best efforts, the rebuilt Mechagodzilla soundly trounced the guardian. However, Godzilla joined the fight and cooperated with King Caesar in decapitating Mechagodzilla, causing the robot to detonate in defeat.
