Geronimo is a young Native American of the Cherokee tribe who was born a regular human. His eyes are partially hidden behind his forelock and he has brown skin. As a boy his life was saved by a Choujin (later revealed to be the God of the Superman Road) and from then on he yearned to become a Choujin. Because of this he hides that fact that he is human and takes part in the battle against the Devil Knights. During the Five Story Ring battles, he shows that his Choujin Tamashii(超人魂,Superman Spirit) exceeds that of a Choujin by defeating Sunshine in a tremendous victory.
