Cast and Crew of Fanboy and Chum Chum

Fanboy and Chum Chum

Fanboy and Chum Chum are fans of all things science fiction and fantasy, and wear wild superhero costumes with their underwear on the outside. Their lives are filled with adventure, from Fanboy's teacher turning into a zombie to an ice monster operating the Frosty Freezy Freeze machine. Their pal Kyle usually tags along on their escapades. Kyle is a real wizard, but Fanboy and Chum Chum are oblivious to his mystical powers, although they live in a world of fantasy.
