The character is depicted as a star-faring outlaw who leads the Starjammers, the father of X-Men members Cyclops and Havok, and the supervillain Vulcan, and the grandfather of Cable, Spider-Girl, and Rachel Summers.

Running out of patience, Cockrum showed the Starjammers, including Corsair, to X-Men writer Chris Claremont, and convinced him to use the characters for this series.

[2] Many years ago, a test pilot for NASA, United States Air Force Major Christopher Summers, was flying himself, his wife Katherine Anne, and their two young sons Scott and Alex in their private airplane, a rebuilt de Havilland Mosquito, down the Western American coast from Alaska when their plane was attacked by a starship from the alien Shi'ar Empire on an exploratory mission to Earth.

Unable to find more than one usable parachute in time, Katherine Anne put it on her eldest son Scott, told him to hold onto Alex, and pushed them both out the plane door, hoping to save them both.

The Starjammers allied themselves with a group of neutral worlds calling themselves The Clench who provided the pirates with a navigator named Keeyah.

During one of the Starjammers' rescue missions, they discovered a vessel belonging to the alien Uncreated, a race of militaristic atheists who intended to destroy any culture that practiced a form of religion, including the Shi'ar.

Seeing the Shi'ar as the lesser of two evils, Corsair chose to stop the Uncreated which earned the Starjammers Lilandra's thanks and a pardon for their crimes.

The Starjammers would later aid the Shi'ar in fending off the threat of Galactus, and subsequently helped Lilandra and Xavier during their efforts to free Earth from its sentence as an intergalactic prison planet.

Corsair felt that since he could not keep the plane from crashing and that he could not save his own wife, that Scott and Alex were in better hands in the care of the various homes that his two sons stayed at rather than with him.

Corsair decided to support the X-Men (this time the group includes Rachel Summers, Nightcrawler, Warpath, Darwin, Polaris and Professor X) and Lilandra in preventing D'Ken from becoming emperor once more (with the help of Vulcan and Deathbird).

[16] Subsequently, Alex (Havok) becomes the new leader of the Starjammers, who now include Corsair's granddaughter Rachel, Polaris, and original members Ch'od and Raza.

[17] When a time-displaced teenage Jean Grey is kidnapped by the Shi'ar to be placed on trial for her actions as Phoenix, the All-New X-Men and the Guardians of the Galaxy teamed up and traveled through space to save her.

[19] The time-displaced Cyclops would later learn that the Starjammers under the insistence of Hepzibah, made a deal with the mysterious Shrouded, who brought Corsair back to life.

The serum was illegal, banned by all governments across the cosmos due to the threat it posed, as it allowed A.I.s to use a living body as a host.

Summers eventually led a mutiny against his captors and for years the Starjammers tried to take their revenge on the Shi'ar, who were fighting a losing war of their own against the Brood.

[volume & issue needed] While sweeping the perimeter, Scott encountered a chained Misty Knight along with the bodies of Colleen Wing and the scavengers Christopher had slain.

Sinister claimed that he had learned of Christopher's transformation and concealed his return from Scott and Alex until he could cure their father.

[volume & issue needed] Corsair appears in Marvel: Ultimate Alliance, voiced by Scott MacDonald.
