Cyclops is a character in the X-men mutant universe who is capable of concentrating a beam of focused optical blast from his eyes. He is forced to wear specialized glasses made of ruby quartz which help to prevent the blasts from penetrating the unique composition of the glasses. He is also known as Scott Summers and was the very first X-man recruited by Charles Xavier. He is also the leader of the field team of X-men who go out on missions. He is the most enthusiastic X-man which dreams of human and X-men equality and strives to make it a reality. The big problem is that everyone else does not see the world how he does and this makes it difficult to help others.

Scot has a nickname of Slim, which is usually called by either of his two wives while they were alive. He is a widower to Madelyne Pryor and Jean Grey. Madelyne Pryor is actually a clone of Jean Grey and had a son with Scott. The X-men world is full of alternate realities and Scott was a large part of most of them. The big difference in most of the alternate realities is that he has different children and those include: Marvel Girl, X-Man, Ruby Summers, Cable and Stryfe who are all endowed with mutant powers. The variations of the character change over time and his physique gets more muscular with the newer variations.
