Kenzo Kabuto appeared after Dr. Hell escaped in the last battle in the guise of a prophet foretelling the arrival of the Mycenae Empire. By the time Koji fought against them critically injured, Kenzo cast off his disguise to have the Great Mazinger attack the Warrior Beasts. Kenzo gave his son a cyborg body so that he could survive while leaving after the operation was done. Afterwards, Kenzo served as an advisor to Tetsuya and Jun even after they were forced to go on the lamb. During their running, Kenzo reunites with Koji.
