Brawl or sometimes referred to as Devastator is the weapon specialist of the Decepticons (obvious, since he's a tank). He's a warrior. That's kind of like calling Cybertron a hunk of metal (which it kind of is). Brawl does not just enjoy fighting, he is consumed by it. Tearing Autobots apart is embedded into his very core, and every fiber-optic cable of his being is obsessed with wild, unyielding combat. The only thing he enjoys, or even cares about, is the fury of battle. And he loves a good explosion. Particularly if it's one he created, and if it was an Autobot that is exploding.
