Guyver
Inspector Risker, an agent of Chronos, was sent to Japan to oversee the recovery of the Guyver Units.
He became the host body for the second Guyver Unit when, either by design or by accident, he activated the recovered unit.
Risker then decided, after yet another failure by the zoanoids, to go after Sho and the first Guyver Unit himself.
Sho was no match for Risker, who was better trained, and was in grave danger of losing the battle when he noticed that Risker's control metal had been damaged.
Sho destroyed the metal and Risker was devoured.
