Shota Yamamori

Shota Yamamori (山守 正太, Yamamori Shōta) is a protector of nature who lives in Mt. Nekura by himself. When the Biomen first encounter Yamamori, Shiro ponders the possibility of whether Yamamori might carry Bio Particles within him. After falling in love with Jun, Yamamori desperately tries to join the team, but is ultimately rejected when the BioRobo finds no traces of Bio Particles within his body.

Disillusioned, Yamamori is tricked by a disguised Farrah into undergoing a procedure that would transform him into the Magne Warrior (マグネ戦士, Magune Senshi), which puts him under Gear's control. However, Yamamori manages to break free of Gear's influence and helps the Bioman team destroy the Magne Megas at the cost of his powers.

During the Great Legend War, Shota did not fight because he had lost his powers.
