Gaia (ガイア, Gaia) is the leader of a soldier group from Hokkaido. Gaia had a split personality. He's an alter ego of Nomura (野村, Nomura).
He is a super-soldier known as "Mr. War" (ミスター 戦争, Misutā Sensō).
Baki the GrapplerEdit
He was once a reckless mercenary called Nomura who loved killing. He was captured and put in front of a firing squad during the Ugandan Bush War. However, as fate would have it, he was rescued at the last second, but the rush of adrenaline and fear caused a split in his personality and all his hair fell out. As a result, whenever Nomura experiences an adrenaline rush, he switches to Gaia.
When it comes to jungle warfare, he is considered to be the king. He can control the body's natural limit-breaker of adrenaline to push himself to whatever level of strength, speed, and awareness that the situation requires. His belief is that he does not need to put on the additional muscle mass in order to be stronger, because he can merely manipulate the level of adrenaline his body is putting out.
As a soldier, Gaia is very good in using weapons. He can using an acid capsule to blind his opponent by spiting it from his mouth. During a fight with Musashi Miyamoto, he used a makeshift knife which have a spring that can shoot the knife with a speed of 60km/h.
