Cyclops (Scott Summers) is a fictional character, the leader of the X-Men superhero team in the Marvel Comics Universe. A mutant, Cyclops emits a powerful energy beam from his eyes (an "optic blast"). In uniform, he wears a battle visor with a single, ruby-quartz lens running eye-to-eye; the resulting one-eyed appearance is why he is codenamed "Cyclops."
Created by writer Stan Lee and artist/co-writer Jack Kirby, he first appeared in The X-Men #1 (September 1963). Originally dubbed Slim Summers, by X-Men #3 his name was changed to Scott -- Slim became just a nickname. Scott is the first X-Man recruited by Professor Charles Xavier; Xavier hand-picks Scott to lead his X-Men, and to carry on the legacy of his mutant-human-harmony ideals. Xavier views Scott as one of his most -- if not the most -- prized pupils; their relationship exhibits father/son qualities. From time to time Scott's extreme loyalty to Xavier has cost him dearly in his relationships with others; but, over the course of the characters' publication history, he eventually emerges from Xavier's shadow as the X-Men's undisputed leader.
Cyclops' is most often portrayed as the archetypal hero of traditional American popular culture -- the opposite of the tough, anti-authority, anti-heroes that emerged in American popular culture after the Vietnam War (e.g., Wolverine, his X-Men teammate). Selfless, self-disciplined, and ethical, Cyclops also possesses tremendous leadership abilities, and great tactical and strategic skills.
He is the son of Corsair (Major Christopher Summers) of the Starjammers; the brother of Havok (Alex Summers) and Vulcan (Gabriel Summers); the father of Cable (Nathan Summers); and, the widower of Madelyne Pryor and Jean Grey. He is also a long-time friend of Beast (Hank McCoy). In alternate realities, he has also been the father of Rachel Summers and Ruby Summers, and a biological parent of X-Man and Stryfe. In 2006, IGN.com rated Cyclops #1 on their list of Top 25 X-Men from the past forty years. Wizard Magazine also ranked Cyclops the 106th best comic book character of all time, of their list of the Top 200 Comic Book Characters of All Time. In 2011 IGN ranked Cyclops 39th in the "Top 100 comic books heroes".
