|“|| Leo choked. "Your mom is a rainbow goddess?"|
"Got a problem with that?" Butch said.
"No, no," Leo said. "Rainbows. Very macho."
"Butch is our best equestrian," Annabeth said. "He gets along great with the pegasi."
"Rainbows, ponies," Leo muttered.
"I'm gonna toss you off this chariot," Butch warned.
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 the end of The Last Olympian. However, he may have fought with the Hermes' cabin as that would have been the cabin he was assigned to.
Butch is seen with Annabeth Chase when they arrive at the Grand Canyon on a chariot looking for Percy Jackson. Once they learn Percy is not there, Butch points out that Jason only has one shoe and Annabeth realizes that Jason was the clue Hera told her about. Butch then flies Jason Grace, Leo Valdez, and Piper McLean to Camp Half-Blood, using the chariot he borrowed from the Apollo cabin. While on the ride Leo makes a sarcastic side comment that Butch's mother is the goddess of rainbows and how manly he is. Butch then threatens to push him off of the chariot. As they arrive back to camp, the chariot is damaged and Butch manages to land it in the lake, much to the irritation of the Apollo cabin. He later appears at the head counselor meeting and is seen sticking colored pencils up the nose of Clovis, who is sleeping.
Butch is seen in Nico di Angelo's dream. He is seen in the council of war, commenting that if Ella flew away she would be "committing suicide." Butch goes on to state "with those Roman eagles in the air, flying isn't safe. I've already lost two pegasi."
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 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.
Since Butch doesn't have many appearances in The Lost Hero, his true powers are unknown although he has the ability to travel at very high speeds. He displays this power when the chariot wheel catches fire at the beginning of The Lost Hero. He also is a very skilled equestrian.
- Leo calls him the "rainbow pony dude."
- His name means "tough kid".
