Captain Colonicus is an honorary member of the League of Heroes. He is a superhero whose powers are colon-based, most of them relating to his farts. For instance: can fly by farting. He appeared in the episode Ghostesses in the Slot Machine. He doesn't appear to be a parody on a superhero like others are and the joke about his is derived around the gag that all of his superpowers are fart jokes.
Captain Colonicus is a muscular superhero with a sculpted face and short orange hair. He wears a black mask over his eyes. He wears a brown jumpsuit with a yellow cape. The logo on his jumpsuit is a black oval with dark yellow in the center.
