Captain Napalm is a minor alter ego of Calvin's. He appeared in a single weekday strip.
Description
Calvin entered a closet and changed into his alter ego, who claimed to be "defender of truth, justice and the American Way", only to call for his mother after finding out he locked himself in. The alter ego predates the introduction of the Captain Napalm comic book, and as such was most likely not based on the character, but rather an original creation akin to Stupendous Man.
