Brawn is not the kind of bot you want to get on the bad side of. Though his size puts him even in the shadow of a certain small yellow bot, his strength surpasses that of even one of the bulkiest of Autobots. Those who are (foolishly) unaware of this tend to underestimate him often. But once he's entered a battle, this grumpy bot heads in full on with brute force, letting his fists do the talking for him. Don't try sarcasm on this guy unless you live near a hospital.
