Calvin In Superhero Form is a minor alter ego of Calvin's. He appeared in two strips. In one, Calvin wearing a cape attempted to fly ("Up, up, and AWAYYY!"), but fell to the ground, to which he blamed Kryptonite for. (This may have also been Calvin pretending to be Superman.) In the other, Calvin pretended to be an unidentified superhero. Although he began saying "This is a job for... [Stupendous Man]", he lacked Stupendous Man's trademark mask, and as such, was probably just pretending to be a generic superhero. The strip depicted him getting tangled up in his cape.
