Cyber-Zilla (サイバージラ?) is the original SaibājiraZilla that nested in New York. The aliens from the Leviathan spaceship resurrected it using alien and human technology. It is completely under the alien's control, although it does recognize Zilla Junior as his son.
Zilla Junior chooses Nick Tatapoulos over Cyber-Zilla and fights him. As he and his son fight, his right cybernetic arm is accidentally blasted off by tachyon fighters. Zilla Junior later viciously tears off the metal covering for its chest and tears out many of his wires, causing the rest of the creature to short-circuit. It is the most violent defeat of a monster shown in the series, with Cyber-Zilla even giving a final death rattle.
Cyber-Zilla's roar was changed to a more metallic sound and its skin color was changed to a light brown, showing decay. Its Atomic breath is blue, like the real Godzilla, and it has a disk in its chest which can reflect weaponry and can fire missiles from its dorsal plates.
