Many of the "superheroes" are the same person.
Some one-shot superheroes have anatomical differences (such as Long Arm Man) or physiological peculiarities (such as Seizure Man). Others can only fly and speak, such as Superjerk, LOL Fag, and LMAO Butts. The latter may be all one character, just in different costumes each time.
