The Marvel mutant Scott Summers is better known as Cyclops.
Cyclops is one of the original and most recognizable members of the X-Men. Scott Summers is a mutant whose eyes emit powerful concussive energy beams. Because he cannot safely control the blasts with his eyes alone, he traditionally wears ruby-quartz lenses in a specialized visor or pair of glasses.
In the comics, Cyclops was the first student recruited by Professor Charles Xavier and became the X-Men’s original field leader. His tactical discipline and leadership often place him at the center of the team, even when other characters—especially Wolverine—receive more public attention. The name “Cyclops” refers to the mythological one-eyed giants, although Scott’s power is not literally a single eye: both eyes project the energy.
Cyclops is Scott’s superhero codename, not his real name. Jean Grey, Cable, and Havok are closely associated with him, but none is an alternative answer to this question.
