Butch is the sort of "get things done recklessly" type of guy. He can be smart mouthed at times and may let his anger get the best of him. Besides that, he may sometimes parrot what Brick says, mostly when making fun of Boomer.
After being revived from the dead, they realized the place was a mess and they couldn't defeat the Powerpuffs alone. So they went to the heroes and offered themselves as worthy sparring partners. A smart assed Shadow said "When you find them let us know." and after some pursuading the got the heroes to belive they weren't new clones of the PPGs and they were trained in the ways of the heroes and learned almost all of their techiques. When it came time to fight the Powerpuff Girl's once more, they gave it their all and almost one, but the girls cheated and used the chaos emeralds they found to activate some new Overdrive Forms(x10). The Rowdyruff's almost die again, but the girls are taken back by Professer. The next time they see the Powerpuffs, they have to save them from the Powerpunks and have to team up with them to beat the Powerpunk Girls.
