The Beginning
A superhero is a fictional character of unprecedented powers dedicated to acts of derring-do in the public interest". Since the debut of the prototypical superhero Superman in 1938, stories of superheroes have dominated American comic books and crossed over into other media. The word itself dates to at least 1917.



Super heroine
A female superhero is sometimes called a super heroine. By most definitions, characters need actual superhuman powers to be deemed superheroes, although terms such as costumed crimefighters are sometimes used to refer to those without such powers who share other common traits with superheroes. The two-word version of the term is a trademark co-owned by DC Comics and Marvel Comics.
