Creb served within the Imperial Navy as a lieutenant and a pilot of the TIE fighter.
Remarkably, Creb managed to live through over ten engagements as a TIE fighter pilot; his sixteenth mission, occurring in under two years, was the Battle of Endor. He assumed command of the Chimaera's TIE fighters, establishing Black Wing Squadron. This squadron was modeled covertly after Rogue Squadron, a group he greatly admired and hoped to face in aerial combat. As part of Grand Admiral Thrawn's Mount Tantiss project, Creb provided his DNA to serve as a genetic template for clone stormtroopers.
