If Brawl's on the battlefield and you can't hear him coming, it's time to check your audio receptors, because chances are you've gone deaf. Brawl's main distinguishing characteristic is VOLUME. No matter if he's talking (yelling), moving (clanking and rattling), or fighting (yelling, clanking, rattling, and blasting) you're sure to hear him doing it, as is anyone else in the county. As if that wasn't enough, he is also a ball of barely contained rage and violence with a hair-trigger temper. This makes even his comrades wary, but it does make him a force to be reckoned with on the battlefield... as long as the mission doesn't require stealth. Or zero casualties.
Brawl combines with his fellow Combaticons to form Bruticus.
His alt-mode is a dark green Leopard Tank
