The last line of defense for the Autobots, Omega Supreme was literally built for heroic sacrifice. Grimly aware of the heavy combat toll his friends must have suffered for him to even be activated in the first place, Omega Supreme does not hesitate to unleash his colossal firepower and risk his own life and safety on their behalf. In fact, he did perish during the Great War, after which the Autobots used his dead body as a spaceship to ferry a maintenance crew around. But he got better.
