Havok' history is presumably similar to his Earth-616 counterpart's. Instead of remaining on Earth, he and Scott joined their father Corsair in outer space and became the Starjammers along with their stepmother Hepzibah and the bounty hunting duo Rocket and Groot.
One day, the Starjammers were approached by Nova Corpsman Johnny Storm who wanted to commandeer their ship to move some sort of object. The Starjammers refused to cooperate, and a fight broke out between the two parties. The fight was halted when the Shi'ar Imperial Fleet revealed that Storm was a fugitive wanted by the Shi'ar Empire and threatened to destroy the Starjammers for harboring him. The Starjammers were able to escape thanks to a space route provided by Storm. Then it was revealed that Storm was aiding Majestrix-in-exile Lilandra Neramani flee from her brother Emperor D'ken who planned to use the Phoenix Force to retake her throne. It's unrevealed what became of this plan.
