Fiction

Marvel Comics continuity

Not long before Optimus Prime and his crew launched from Cybertron in the Ark to clear threating asteroids, he was defending the Jan-Ja in what seemed to be a doomed attempt to keep the Decepticons from taking Iacon. One of Prime's unnamed officers urged Prime to surrender. Prime told him to get out the white flag. Relieved, the officer unfurled it only to be shocked when Prime ordered him to bind his wound with it. With that, Prime ordered a charge, which was apparently successful in protecting Iacon. Surrender!
