The Powerpuff Girls was created by Craig McCracken and premiered on Cartoon Network in 1998, following Blossom, Bubbles and Buttercup, three kindergarten aged heroes created by Professor Utonium who protect Townsville from villains like Mojo Jojo. The series became one of the channel's defining cartoons, spawning merchandise, a film and a lasting online fandom. Short clips and theme sounds from the show now circulate on soundboards and social media, where fans reuse them for team entrances, childhood nostalgia posts and edits celebrating girl power and teamwork.
