Oppressor Plutonium hated the way that the Powerpuff Girls saved the world. So therefore, he decided to create his own daughters using: salt, vinegar and everything nasty, with the ingredient: Chemical X. And their names were: Berserk, Brat and Brute. Berserk was the leader, Brat was the cute, but dangerous one and Brute was the brutal one. And they were the Powerpunk Girls, the Powerpuff Girls' evil counterparts.
