The Rowdyruff Boys

The Rowdyruff Boys were a team of villains, who were created by Mojo Jojo as a foil to the Powerpuff Girls. They are male counterparts of the Powerpuff girls.

In Powerpuff Girls
The Rowdyruff Boys are the male counterparts of the Powerpuff Girls sett to Mojo Jojo using a mixture of "snips and snails and a puppy dog tail" in a prison toilet in the episode called The Rowdyruff Boys. His replacement for chemical X was in fact toilet water, as Mojo Jojo believed that would have the same potency as chemical X. An important difference between the trios is that the Powerpuff Girls got their names from Professor Utonium and the name of their team from the narrator, while the Rowdyruff Boys named themselves and their team.

The trio is composed of:
 * Brick (voiced by Rob Paulsen): Blossom's equivalent, he is the quick-tempered leader of the Boys, but possesses little of Blossom's tactical logic. He often goes off on gloating tangents that irritate even his brothers. One main difference between him and Blossom is that he is almost always the cause of most of the arguing and violence within the group, whereas she is the group's peacemaker. He wears a red baseball cap compared to Blossom's bow. He also originally had bangs, which are replaced with a long spiky hair down his back. He still has the bangs like Blossom, but they are hidden underneath his cap. After his resurrection. Brick is also often shown to hit Boomer for no reason other than his own amusement. His signature color is red.
 * Boomer (voiced by Rob Paulsen): Bubbles' equivalent, he is a loud-mouthed dimwit, as opposed to Bubbles' naive sweetness. One main difference between him and Bubbles is that he is not as easily disgusted as Bubbles is. His hair parts in a curved fashion like Bubbles's; it goes on longer on each side. After his resurrection, his hair is longer and spiky on each end, in a wings haircut. His signature color is blue.
 * Butch (voiced by Roger L. Jackson): Buttercup's equivalent. He was once seen to be more aggressive than Brick. One main difference between him and Buttercup is that he has no sense of conscience, whereas Buttercup will occasionally apologize for her mistakes. Butch will sometimes keep moving up and down while standing, as though he is hyperactive. He shares Buttercup's small triangular hair parting, and sports a small cowlick at the top of his head in place of Buttercup's flip. After his resurrection, all his hair is spiked upwards, leaving the cowlick. His signature color is green.

In Powerpuff Girls Z
