Powers: Cyclops' eyes constantly fire red energy beams. At full power these beams can punch through mountains. However, Cyclops cannot control his power, and is forced to always wear a ruby quartz visor, glasses or goggles. He has an uncanny ability to compute trigonometric relations, which allows him to bounce his optic blasts with incredible accuracy. His greatest fear is losing control of his powers and hurting someone he cares for. Cyclops is immune to his brother Havok's power, and vice versa. Scott's power first manifested when his parent's plane was attacked by a Shi'ar spaceship. Scott and Alex were pushed out the hatch with the sole parachute, which caught on fire as it opened. Clutching Alex to him, Scott stared down at his doom, until his eyes began to blast red beams of energy, which softened the ground, cushioning the brothers' landing. Scott and Alex were taken to an orphanage run by Sinister, where they were secretly subjected to tests to determine their power level. Alex was fostered out, but Sinister had plans for Scott, having realized that Summers DNA would produce a mutant of incomparable power when combined with DNA from the Grey family. For much of his time in the orphanage, however, Scott was in a coma induced by Sinister's experiments, and used to control his awesome power. Somehow, Scott was taken in by Professor Charles Xavier, and became Cyclops, the first X-Man and heir to Xavier's dream. From the start Cyclops was the X-Men's field leader, and almost as quickly, he and Jean Grey fell in love. Years passed, and althought the original X-Men were replaced with a new batch of heroes, Cyclops stayed on as team leader, until his lover Jean, now the Phoenix, died on the Moon. Actually, Phoenix was not really Jean, but a clone created by the Phoenix Force, which had succumbed to the dark side of human emotions and had become Dark Phoenix. After Phoenix's death, Scott was overcome with grief, and left the X-Men. He became a fisherman in Florida, and started a relationship with Alettys Forrester, the captain of his ship. Scott soon returned to the X-Men, however, and after being abducted by the Brood, considered joining his father Corsair, who had been captured, not killed, by the Shi'ar, aboard his ship, the Starjammer. But Scott remained on Earth, and went to visit his grandparents in Alaska. On that trip, he met and fell in love with Madelyne Pryor, a pilot who looked EXACTLY like Jean Grey. Actually, Maddie was Jean's clone, created by Sinister to fulfill his dark plan of creating a super-mutant. The two were married, and in time, had a baby boy, Nathan Christopher Charles Summers. Tensions were rising between the couple, and when Scott lost a duel for leadership of the team to Storm, they left for Alaska. Unfortunately, things didn't work out, and Scott left for NY to rejoin the members of the original X-Men and found the team called X-Factor. The fact that Jean Grey was found alive by the Fantastic Four only added to his confusion over his life and loves, and he remained in NY, almost forgetting about his wife and child. At some point, Scott was reunited with his son, probably around the time that Maddie was rejoining the X-Men in San Francisco. When the X-Men "died" in Dallas, Scott felt truly free to pursue Jean once again, but when Madelyne reappeared as the Goblin Queen, she stole her son back and swore vengeancce against her husband for abandoning her. X-Factor and the X-Men defeated Maddie and saved Nathan's life from being sacrificed to create a demonworld, and Scott's life returned to what passes for normal for an X-Man. Shortly thereafter, Scott discovered that Rachel (Phoenix II), whom he had met while still on the X-Men, was actually his and Jean's daughter from a possible future. Summers family life complicated itself even further when Apocalypse had his Dark Riders infect Nathan Christopher with a techno-organic virus. The virus would have killed the boy if Askani had not arrived from the future and offered to take him forward in time, where his life could be saved. Cyclops made one of the hardest decisions of his life by allowing his son to be taken away. Soon after, the members of X-Factor rejoined the X-Men, and in time, Scott and Jean were married (even though once before Jean had refused Scott's proposal). On their honeymoon the couple was assaulted by a telepathic wave that propelled their minds 2000 years into the future. There Scott became Slym, and with Redd (Jean) raised his son Nathan, the boy who would grow up to become Cable. The "Dayspring" (Summers) family also helped to defeat Apocalypse, the despot of the time, before being pulled back to the present. Scott was injured during Operation: Zero Tolerance when Bastion had a bomb implanted in his chest: only the medical expertise of Dr. Cecilia Reyes and some unique surgical tools saved his life. Scott left the X-Men to recuperate, and with the recent telepathic shockwave released by the Shadow King crippling his wife's powers, remained away for some time afterwards, contemplating some new ideas about making Xavier's dream into their own. However, he and Jean returned to assist the Mannites against Death III. When that mission ended in the death of Wolverine, who was revealed to have been a Skrull impostor, Scott (and Jean) agreed to stay on to lead the team once more. After infiltrating the Skrull base and discovering that the real Logan was Death III, all the X-Men prepared for the final battle with Apocalypse. During the fight, Scott and the rest of those who had been revealed as The Twelve were captured by Apocalypse and hooked into a machine that would channel their awesome energies into hom, allowing him to absorb X-Man's body and ascend to the cosmic stage. When the Living Monolith broke free, Scott attacked Apocalypse, but his powers were drained. As the other X-Men fell around him, Scott, still powerless, saw only one option and pushed Nate out of Apocalypse's draining circuit. Unfortunately, since Scott shared most of the same genes, Apocalypse was able to absorb him instead into a new evil entity. Although Apocalypse then used his new power to warp time and space to trick the X-Men into recreating the circuit, Jean felt Scott inside Apocalypse and prevented the X-Men from destroying him when they discovered the ruses. No one else was able to sense Scott, however, and he is presumed dead by most of his teammates.
