Percy Jackson and the Olympians: Legends

Butch is a bulky male with a shaved head, has a face like a pile of bricks, and a rainbow tattoo on his biceps and is seen wearing a Camp Half-Blood shirt.

Though little is known about him, Butch seems to be very violent towards people like Leo, while traveling to Camp Half-Blood, and Clovis at the counselor meeting. He also seems to be less than tolerant with Leo, who insulted him about being the son of Iris and his skill as an equestrian, implying he could be emotionally sensitive. Perhaps the nature of his mother is a soft spot of his, and he is not usually so irritated. Ironically, his mother, Iris, now has a peaceful, non-violent attitude, and only attacks in self-defense.

Butch is a camper at Camp Half-Blood. It is possible that Butch didn't fight in Second Olympian war because he is a son of Iris and there wasn't a cabin for Iris at Camp Half-Blood until a few years ago. However, he may have fought with the Hermes' Cabin as that would have been the cabin he would've been assigned to. Butch seems to have an unfriendly rivalry with Leo Valdez after he made a sarcastic side comment that Butch's mother is the goddess of rainbows and how manly he is.
