Brawl was in his tank form and drove across the road with Barricade and Bonecrusher. Barricade used his siren to clear room and Bonecrusher knocked cars out of the way. Brawl was nowhere to be seen when Bonecrusher attacked Optimus and was killed.

Brawl eventually made it to Mission City in the middle of a large abttle between the Decepticons and Autobots. The Autobots were suffering heavy losses, with Jazz being killed by the Decepticon leader Megatron and Bumblebee, Ratchet, and Ironhide being heavily injured by Starscream. Brawl took part in the battle and fought against the military. He took damage but instantly got back up and continued the fight. Finally Bumblebee was driven over to Brawl and he shot Brawl in the face with his cannon, finally destroying Brawl. The military checked to see if Brawl was dead and confirmed it.
