Koji Kabuto
Koji Kabuto (兜 甲児 Kabuto Kōji) is the main protagonist of Mazinger Z and the primary pilot of the titular robot, as well as a supporting protagonist in Great Mazinger and Grendizer. Along with the Mazinger, Koji is famed for breaking the mold of main characters of the time, being hot-blooded and confident to the point of arrogance rather than heroic and/or conflicted.
