Brawl is a trigger-happy Combaticon. He has a bit of a temper, which may not mix well with his Tank Mode. He is one of the legs of the mighty Bruticus. He loves to destroy things, which is proven in Transformers: Fall of Cybertron when he is ordered to blast the supports of a bridge, to which he replies "I like blastin' stuff!"

From Transformers: War for Cybertron to Transformers: Fall of Cybertron, he seems to have lost some of his intelligence, as in WFC he seems to have a vast knowledge of weapons, then in FOC he appears only as sort of a half-wit who just wants to break stuff.

"Guns are online, Onslaught! Ready to pound some metal!"

Brawl is playable in an escalation level in Fall of Cybertron alongside Onslaught, Quake, and Swindle. Brawl's ability is to send out a battle sentry that will fight with you.
