Scott Summers (Cyclops)
Creators: Stan Lee, Jack Kirby
First Appearance: X-Men #1 (Sept. 1963)
From what I can tell many Marvel fans find Scott Summers (Cyclops) to be the worst. He’s one of the original X-Men. The oldest son of Christopher Summers (Corsair), Scott became the first student of Professor X. He was given a visor made of quartz. He was also made the deputy leader of the X-Men. In the X-Men animated series Cyclops was presented as a “boy scout,” always following the rules regardless of the consequences. He was a bit of a teachers pet and often though he was superior to others. Furthermore, he would often find himself in conflict with fan favorites Storm and Wolverine. In the comics Cyclops became a cheater and a murderer.
Treatment of women
Scott had developed a tendency to move on to quickly or abandoned women. When Jean Grey dies (the first of many deaths) he moves on quickly with Colleen Wing when he thinks Jean dies in a volcanic explosion. When Jean dies during the Dark Phoenix saga he moves on with her clone, Madelyne Pryor. Worse, when he found out that Jean was actually alive he abandoned Madelyne and their child. At some point he became unsatisfied with his married to Jean, he began a psychic affair with Emma Frost. His excuse? It didn’t really count because it wasn’t physical.
Power hungry murderer
During the Avengers vs X-Men event, Scott becomes possessed by the Phoenix Force. While he initially wanted to protected Hope Summers, he became drunk with power. When the Phoenix Force spits in five among Scott, Emma, Magik, Namor and Colossus, he goes full Dark Phoenix. He tries to kill many of the Avengers and X-Men that try to stop him. During this arc Scott kills Professor X as he tries to stop him. Cyclops was imprisoned in a ruby quartz cube.
Revolutionary and war criminal
While in prison Scott becomes more political. He originally sees himself as a matyr but after the murder of a fellow mutant he decides that he would be more effective on the outside. Magneto frees Cyclops from his prison. He then goes on to attack cops and attempts to start a “mutant revolution.” He also becomes inspiration for a mutant uprising called “The Ghosts of Cyclops.” While you could argue that Cyclops was justified in fighting for mutant-kind, his means were violent.
