The Starjammers are a team of space pirates and freedom fighters who frequently interacts with the X-Men and the Guardians of the Galaxy. Their leader is Corsair, aka Christopher Summers, the father of Cyclops, Havok and Vulcan.
The story of the Starjammers began with Christopher Summers returning with his family from a trip to Alaska . Without warning their plane was attacked. Chris's wife, Katherine, strapped their two sons (Scott Summers and Alexander Summers, who later became the X-Men Cyclops and Havok ) to their only parachute and pushed them out of the plane, saving their lives. The husband and wife were then teleported from their plane to the ship of an advanced alien race called the Shi'ar . This had been a scouting mission to bring in human specimens . They were brought before D'ken , the mad ruler of the Shi'ar Empire, who was immediately smitten with Katherine, making her his concbine and sending her husband to the slave pits. Eventually, Christopher escaped and reached D'Ken's private quarters to try to kill him. However, he was caught and punished by having his wife murdered before his eyes, and his unborn son(who later became Vulcan) cut out of her womb. His spirit broken, he was sent to a camp on another planet.
While working in the mining camp, Christopher witnessed the guards mercilessly beating a feline-like female. He stepped in, trying to get them to stop, but was then beaten himself. The woman was taken to the holding cells and Christopher huddled up in a corner, ashamed of himself. A little while later, Raza and Ch'od passed by and asked Christopher for the whereabouts of their comrade Hepzibah. Christopher was too afraid to answer. After they had left, he felt guilty and went to the guards' quarters, starting a fight after killing one of them. Raza and Ch'od jumped in, and together they got past the guards, freed the cat-woman, and sneaked on board a Shi'ar starship. Christopher used his pilot call-sign, Corsair. Naming Christopher their captain, they became the Starjammers, a group of space pirates rebelling against the Shi'ar tyranny.
