Gou, Mantarou

剛万太郎

The primary antagonist and a significant antihero in the Cybrog Kuro-chan manga and anime series. He is a mad scientist who seeks world domination by creating cyborg cats as weapons of mass destruction.
His scheme completely backfired when Kuro removed the control chip through his own sheer willpower. He subsequently abandons his plans for world domination and chooses to live a more peaceful life with Mi and later Kotaro. Although his relationship with Kuro is turbulent and hostile at times, Kuro respects him as an inventor.
