Captain Underpants

Mr. Benjamin "Benny" Krupp a.k.a. Captain Underpants (voiced by Ed Helms) is the (former) tertiary antagonist-turned-tritagonist of the film, Captain Underpants: The First Epic Movie. After glaring at Harold Hutchins and George Beard, by placing them into separated classes (for getting rid of their friendship and pranks), he was hypnotized into the duo's created comic book hero; The Amazing Captain Underpants.
