Genbu is the weakest of the Four Saint Beast with a rating of an upper D-Class demon. He is comprised of stone and can meld with any stone and swim through it like fish and water. He has a level of superhuman strength though his true power is the ability to seperate his body into stone pieces and shoot them at the opponent. This attack is normally devastating though this exposses his weakness, a glowing rock that serves the same purpose of the human hypothalamus.
Exploding Boulder Bomb:
Genbu slips his body onto multiple rocks and boulders and fires his body pieces at his opponent making it similar to Yusuke's shotgun though this moves exposes his control core stone that can kill him if it is hit.
