History: Over thirty years ago U.S. Air Force test pilot Major Christopher Summers was flying himself, his wife Katherine Anne, and their young sons Scott and Alex in a private plane down the Western American coast from Alaska when it was attacked by a starship from the Shi'ar Empire on an exploratory mission to Earth. The Shi'ar, aboard the craft, pursued Summers' plane to prevent his making their presence on Earth known. The Shi'ar craft fired on Summers' plane, a rebuilt DeHaviland Mosquito, made of wood, causing it to burst into flame. Unable to find more than one usable parachute in time. Katherine Anne Summers put it on her older son Scott, told him to hold onto Alex, and pushed them both out the plane door, thereby hoping to save them. Thus Scott and Alex escaped the Shi'ar; although Scott suffered a head injury in the fall which would later affect his powers as Cyclops.

Christopher and Katherine Anne Summers were teleported aboard the Shi'ar starship and taken to the Shi'ar Imperial Throneworld. There Christopher Summers was separated from his wife and imprisoned. He broke free and discovered the corrupt Shi'ar emperor D'ken attempting to rape Katherine Anne. D'ken responded to this interruption by murdering Katherine Anne before Summers' eyes, and then ordering Summers sent to the slave pits, where criminals and political prisoners were held.

In the slave pits Summers met Ch'od, a Saurid, a Mephitisoid whom Summers nicknamed "Hepzibah," and Raza, a Shi'ar cyborg. Ch'od and Hepzibah were both members of races that had been made subjects of the Shi'ar Empire. Together the four escaped the slave pits and stole a starship. They called their ship the Starjammer (they have had at least two starships by that name) and themselves the Starjammers, and began engaging in space piracy, thus taking vengeance on the Shi'ar by plundering their starships, but taking care not to harm innocent passengers in the process. The Starjammers therefore were regarded as outlaws by the Shi'ar Empire. Summers was the leader of the Starjammers, whom he led under the name of Corsair. He adopted this name out of his love for tales of adventuring swashbucklers, and he patterned his costume and behavior as Starjammers leader after these fictional heroes of his. Others, such as Binary, have joined the Starjammers since the team was formed.

The Starjammers met the X-Men when the two groups teamed up on a world in the Shi'ar Galaxy to battle the Shi'ar Imperial Guard, who were then serving D'ken. One of the X-Men, Jean Grey, used her telepathic powers to probe Corsair's mind and learned that he was the father of Scott Summers, who had become the X-Man known as Cyclops. At Corsair's request, Grey kept his true identity a secret from Cyclops, but both Cyclops and his brother Alex, now also known as Havok, have since learned who Corsair really is.

Since they had aided her against the machinations of her brother D'ken, the Shi'ar Princess Lilandra, once D'ken had been deposed and she became empress in his stead, put an unofficial end to the Shi'ar Empire's opposition to the Starjammers. However, the Starjammers again became outlaws, since they were known to be Lilandra's allies, once her sister Deathbird, staged a coup d'etat and seized the throne. The Starjammers have since aided Lilandra and the X-Men in their struggle against the alien Brood, who were Deathbird's allies.
