Circuit (Action Master)

Circuit is an Autobot in Generation 1 continuity.

What would it take to put Circuit on the battle field delivering messages for Autobot Command today? Whatever it is he's willing to make a deal, just tell him what you need! He's here to make you happy, after all, and making a deal is his middle name. Circuit is a smooth-talking, easy-bantering used-car salesman who hates to do anything without wheeling-and-dealling first, orders or not. Many of his "deals" however are actually scams and he has to constantly look over his shoulder for vengeful former marks. His formula 1 style vehicle/exo-suit is developed with high speed in mind (like the kind needed to escape from a mob), a cloaking shield (like the kind needed to hide from a mob), and a decelleraor cannon (like the kind needed to slow that mob down till you're sure you've gotten away). These skills and a devestating Gattling gun make him a force to be reckoned with on the battlefield as well, which may be why the Autobots keep him around despite it all.
