In the Generation 1 continuity Bruticus is the combined form of the Combaticons Blastoff, Brawl, Onslaught, Swindle and Vortex. Sometimes Shockwave is also part of combination, serving as a weapon for Bruticus.
Bruticus is a successful merging of the minds of the Combaticons. He can destroy his enemies with ultrasonic waves; he can smash through metal bridges with his arms alone. He uses Onslaught's powerful sonic stun-gun. He is noted for being graceful, fast and willing to follow orders. That is also his weakness, without orders he will often just stand around, doing nothing.
Yeah, I guess I can see that.
