Gasser is the quiet but sensible teenage hero of Bobobo's group. He has short, spiky white hair with short bangs and blood red eyes. The "heppoko" in his Japanese name means "untrained", while "maru" is a common name suffix for a samurai or other type of warrior. He uses "True Fart Fist" (Onara Shinken) as his martial art style. In the English Dub he uses "The Fist of The Back Wind" and was formerly an outcast who was studying Bo-bobo's power. He briefly broke from his trail to literally save the hair of a kidnapped Beauty. Gasser followed them to C-Block Base where he once again saved Beauty, and after Wall Man's defeat joined the team, but he rarely is seen fighting. He is actually mostly seen punching someone. He is another "sane" person among the group like Beauty, though he sometimes joins Bo-bobo in his antics or acts oddly on his own. Also like Beauty, he admires Bobobo from the sidelines and refers to him as "Mr. Bobobo." Like Beauty, Gasser gets shocked if someone does something stupid. Though he doesn't dare tell her, he loves Beauty and though he doesn't know it, she loves him. Beauty's nickname for him is "He-kun" (へっくん, "Gas-Can" in American version). He also is hated by Don Patch.This is because in episode 9 he states that the Bobobo Show is dumb and Don Patch begins to hit him and hate him for that. After being convinced by Pokomi that Bo-bobo's team is evil, Gasser becomes Neo A-Block Base's commander but after being defeated, he rejoins Bo-bobo's group after undergoing a nightmarish training session. (literal torture from Serviceman, Kancho-kun, Ochazuke Alien and even his old friend Fundoshitaro).
