The Powerpuff Girls were made by a scientist named Professor Utonium. He was attempting to create the perfect little girl. The ingredients for his experiment were sugar, spice and everything nice but, by accident, an extra ingredient was put into the experiment and that extra ingredient was Chemical X. This gave the perfect little girls their superpowers.
The Powerpuff Girls were created by Craig McCracken.
Bubbles is the nicest and most innocent of the group. She has blonde hair, wears a blue dress, and can often be seen playing with her favorite toy: a stuffed purple octopus named Octi.
Blossom is the leader of the group. She has red hair and wears a pink dress. She is the most responsible and serious member, and often mothers the other girls.
Buttercup is the toughest of the girls. She has black hair, wears a green dress, and is a tomboy. Though she seems to pick on Bubbles an awful lot, it is clear that she loves her sister.
