Bruticus saw the Trigon trying to rip off his arm, luckily it was Blast Off's side that was being grabbed. Using the Vortex side, he activated his blade shield. The whirling blades threatened to cut Trigons arm off. "What's it going to be, big guy. My arm. or yours!" he shouted. He knew if the arm was ripped off, it wouldn't mean much. Sure, Blast Off would be hurt, but not enough to kill him.
