While Christopher Summers flew the family back from a vacation in his plane, it was attacked and set ablaze by a scout ship from the alien Shi'ar Empire. Christopher's wife Katherine pushed their sons, Scott and Alex (later Cyclops and Havok of the X-Men) out with the only parachute.
On the scout ship Chris managed to escape and looked for Katherine. He found that she had been made part of Emperor D'Ken's 'harem' and was being assaulted by D'Ken. D'Ken killed Katherine in front of a helpless Christopher. Unknown to Christopher or his wife at the time, she was pregnant. Emperor D'Ken ripped the baby from her in front of Christopher. Unknown to Chris, D'Ken had the baby incubated and matured him into adulthood and sold him into slavery.
Corsair was sentenced to work in the mine pits until death, but again managed to escape with a few other prisoners. Stealing a spaceship, the Starjammer, they called themselves the Starjammers. The Starjammers committed piracy attacking Shi'ar vessels. Christopher modeled himself after tales of pirates on Earth and took the name of Corsair. Corsair was in a romantic relationship with Hepzibah, a fellow Starjammer.
Corsair was eventually reunited with his son, Cyclops, when the X-Men ventured into space to repair the M'Kraan Crystal. Phoenix noticed similarities between the two and telepathically discovered their connection, but Corsair made her swear not to tell Scott. Storm also learned of Corsair's real identity.
Months later, Corsair crash-landed on Earth near the Xavier's School for Gifted Youngsters while being chased by Sidri hunters. Scott found him, discovering that Corsair carried a picture of the family. Christopher explained that he and Katherine doubted that Scott and Alex had survived the fall. After her death, he thought returning to Earth would be too painful.
Corsair was instrumental in rescuing Prof. Xavier from the Brood Queen that was inside of him by using the medical facilities on the Starjammer to transfer Prof. Xavier's mind into a clone body. Corsair had a secret conversation with Professor X around this time about Gabriel, the third child he and Katherine had. Scott then introduced Corsair to his other son, Alex and Chris, in turn, introduced Scott with his grandparents.
Scott proposed to his first wife, Madelyne, on the deck of the Starjammer and Chris attended the wedding. After Scott and Alex decided to stay on Earth, Corsair returned to Shi'ar space and frequently aided the X-Men from time to time while running from the Shi'ar Empire and bounty hunters.
When the X-Men came to Shi'ar space to stop his son Gabriel, now called Vulcan, from slaughtering the Shi'ar, Corsair and the Starjammers agreed to help. Confronting Gabriel, who was poised to become Emperor after killing D'Ken, Corsair ordered his child to stop the carnage. Bitterly declaring that he had no father, Gabriel murdered Corsair in cold blood. His place as leader of the Starjammers was then taken by his son, Alex.
The Trial of Jean Grey
When the Guardians of the Galaxy and the past X-Men tried to follow the Shi'ar, who had abducted the Jean Grey of the past to put her on trial for the crimes of the Phoenix, they were discovered and attacked. During the battle, they ran across the Starjammers, who saved them from the Shi'ar, and revealed to have a living Corsair back as their leader.
After the rescue operation, Corsair's time-displaced teenage son Cyclops, having thought his father dead, decided to join the Starjammers. Having captured a hostile Badoon ship, Corsair took command of it together with his son, to explore space, leaving the Starjammers.
Thanos' funeral and Faithless
Following the death of Thanos, Corsair and the other Starjammers attended at his funeral where Eros revealed to the attendants that Thanos had transferred his mind into another body. However, the Black Order crashed in and stole Thanos' body, while opening a rift in space sucking in everyone. Luckily, the Starjammers were saved by Norrin Radd, getting them out of the rift.
The Starjammers were then captured by a future Universal Church of Truth lead by Patriarch, and used them to empower their temple. Thankfully, the Starjammers, along with the Guardians of the Galaxy, were saved by Rocket Raccoon, who reprogramed the ship's engine to banish the church to their original timeline. Afterwards, they paid a visit to a recovering Rocket at a hospital.
They then accompanied the New Mutants to Shi'ar space in order for the team to leave a plant and form a Gateway, connecting Krakoa with the Shi'ar. However, the Starjammers, unbeknownst to the Mutants, planned to steal a relic from the Shi'ar. When they infiltrated the empire, the New Mutants followed behind them, ruining their plans. The Starjammers decided to leave the Mutants behind, while they escaped, not knowing that Wolfsbane switched the relic the pirates wanted to steal with a container.
When the Void, disguised as Sentry, lead the Forces of the Cancerverse to attack the Negative Zone, the Starjammers, along with other heroes, came to aid in the battle, after being called by the Fantastic Four. In the end, the Void remerged with Bob Reynolds, while Nova sacrificed himself in order to defeat the evil forces.
