}}'''Stupendous Man''' is a recurring character in Calvin and Hobbes. He is one of [[Calvin]]'s many [[:Category:Alter egos of Calvin|alter egos]] and an attempted superhero by Calvin. Calvin puts on a red mask and cape which his mom made him, and pretends that other people (mostly the women in his life that he hates) are villains or monsters. When things begin to tilt away from his favor, he takes off the costume, and becomes "mild-mannered millionaire playboy Calvin" (a reference to Bruce Wayne, the secret identity of Batman) once more.
Stupendous Man is Calvin's second most-frequently employed alter ego, even though, according to Calvin, Stupendous Man has only won "moral victories" and not physical ones. He usually gets in trouble. Stupendous Man is also Calvin's most powerful alter ego, achieving such feats as flying a telescope lens into the atmosphere and turning time back a day. However, these powers are largely wasted, either on supervillains that Stupendous Man cannot defeat or on ultimately futile plans such as getting mild-mannered Calvin another day out of school.
* There are two other strips that ran [[Calvin in Superhero Form|Calvin as a superhero]], but it is unknown if this is Stupendous Man.
* Before Stupendous Man, a strip depicted Calvin turning into one of his comic book heroes, [[Captain Napalm (Alter ego)|Captain Napalm]].
* Calvin tries his best to keep his identity secret to everyone else (except for Hobbes), though everyone can tell its him.
