The Rowdyruff Boys

The Rowdyruff Boys are a trio of artificial humans and Bizarro male counterparts of The Powerpuff Girls, created by Mojo Jojo. They were made by flushing armpit hair, snails from the prison cafeteria, and the tail of the talking dog down a jail cell toilet that contained the apparent potency of Chemical X (snips, n' snails, and a puppy-dog tail). They have very similar abilities to the Powerpuff Girls, but they all possess very easily targeted weaknesses, originally an aversion to Cooties (fixed by HIM), shrinkage when their egos are damaged, and an obsession with destroying things that can lead to their own downfall.

In a sense they can be seen as a dark reflection of the Powerpuff Girls and their violent hubris, seeing as how Mojo Jojo had a hand in the creation of the Girls as well as the Boys. The key difference being that while the Powerpuff Girls were created by accident when Mojo Jojo (still Jojo) shoved Professor Utonium accidentally breaking the bottle of Chemical X, the Rowdyruff Boys were created by Mojo on purpose. Mojo also has the opposite feelings for the Rowdyruff Boys in that he sees them as his own sons, while he outright despises the Powerpuff Girls and wants to destroy them. In Powerpuff Reborn, Professor Utonium recreates the Rowdyruffs as the Rowdyright Boys. When in this form they are timid and more like Buttercup. Heroic but brash and rude.

Powers


 * 1) Growing: Whenever the boys get kissed by the girls, they grow bigger, stronger, tougher, more dangerous and more powerful. This was only used once in "The Boys are Back in Town" and it will most likely never be used again because all the Powerpuff Girls need to do is not kiss them again. However, if we count "The City of Clipsville" as canon since the Girls fell in love with the Boys, it's most likely that HIM removed that power from them to prevent the same mistake to be repeated.
 * 2) Afterburner: The boys can emit thick, toxic gas through their farts which increases their speed. It can also temporarily blind and suffocate the girls, as seen in their self-titled debut episode. In order to use this ability, they must have inhaled Burritos or a similar substance of the same magnitude.
 * 3) Sonic Pulse Wave: As seen in "The Boys Are Back In Town", the boys can produce a hypersonic wave that can knock the girls away.
 * 4) Rowdyruff Megablast: As seen in their return episode, the boys can produce an energy blast by creating a whirlpool of pure energy. the girls can do this too but while the boy's energy is bright green, the girls' energy is bright blue.

MAIN WEAKNESS


 * 1) Antidote X: The Rowdyruff Boys share the same weakness to Antidote X that the girls have, as they were also created using Chemical X.
