Cyber-Godzilla

Cyber Godzilla is the original Godzilla that nested in New York City in 1998. Following the creature's death, its corpse was taken to a military base for study. When the Leviathan Aliens overtook the base, they used their technology to modify Godzilla into a cyborg that was completely under their control, using it to turn the second Godzilla against humanity and recruit him to their cause. Cyber Godzilla is completely under the control of the Leviathan Aliens, though he is still able to recognize the second Godzilla as his son.
