Green Lantern is the name of several superheroes appearing in American comic books published by DC Comics. They fight evil with the aid of rings that grant them a variety of extraordinary powers, all of which come from imagination, fearlessness, and the electromagnetic spectrum of emotional willpower. The characters are typically depicted as members of the Green Lantern Corps, an intergalactic law enforcement agency.

A superhero or superheroine is a stock character who typically possesses superpowers or abilities beyond those of ordinary people, is frequently costumed concealing their identity, and fits the role of the hero; typically using their powers to help the world become a better place, or dedicating themselves to protecting the public and fighting crime. Superhero fiction is the genre of fiction that is centered on such characters, especially, since the 1930s, in American comic books, as well as in Japanese media.
