Though apparently unable to talk, Kodama can use his voice to summon magical destructive blue orbs, and throw them at his enemies. The longer and louder he can shout, the bigger and stronger the magical orbs will be. In his last fight, Kodama transformed himself in armored monster called Demon Beast Armored Kodama (魔獣装甲コダマ, Majū Sōkō Kodama?) to fight Garo, but was easily killed by Kouga once he is possessed by his armor. His name is derived from the Japanese word meaning "echo." In the Garo Side Story, you finally see him speak; unfortunately, he talks extremely loud and fast in English, which Kaoru mistakes for a Kansai dialect.
Kodama is portrayed by Mark Musashi (マーク武蔵, Māku Musashi?).
