Cree was a pilot for the Empire. He fought in the Battle Of Yavin, defending the Death Star alongside Darth Vader. Together with Jak Mithel, he assisted Vader in taking down the Y-Wing fighters who attempted to get a torpedo into the exhaust port. They then took down Garven Dreis and his wingmen before trying the same with Luke Skywalker. They scared off Wedge Antilles, destroyed Biggs Darklighter, and then shot up the R2 unit on the final X-Wing. After waiting for a while, they started to fire on the last ship, but Railback's TIE Fighter was shot down by the Millenium Falcon.
He was nicknamed "Backstabber" after some extremely personal photos were discovered in his locker by Sedder Piles.
