A fiercely individual perfectionist, domineering and arrogant (even downright tyrannical), Over-Run acts like the air war with the Decepticons is his own personal responsibility, and he'll yell angry instructions or abuse at anyone of any rank he sees as getting in the way of his winning it. Needless to say, this makes him pretty unpopular with the other airborne Autobots. If he wasn't a very effective warrior in an arena where they are traditionally outmatched, it's unlikely Over-Run would be anywhere but in the brig by now. He IS dedicated to the Autobot cause, though; he just sees beating the Decepticons as far more important than rudeness and the feeling of his inferior comrades. He'll apologize after the war ends. Maybe.
