Circuit (G1)
| The name or term "Circuit" refers to more than one character or idea. For a list of other meanings, see Circuit (disambiguation). |
- Circuit is an Autobot from the Generation 1 continuity family.

"What would it take to put Circuit on the battlefield delivering messages for Autobot Command here, today? Whatever it is, I'm willing to make a deal, just tell me what you need! I'm here to make you happy, after all, and making a deal is my middle name."
Circuit is the type of smooth-talking, easy-bantering used-car salesman who gives used-car salesmen a bad name. More, he hates to do anything without wheeling-and-dealing first, so even his commanding officers have to suffer through his constant "pitches." Many of his "deals," however, are actually scams, meaning Circuit has to constantly look over his shoulder for vengeful former marks back to take revenge. His Formula 1-style vehicle/Exo-suit was developed with high speed in mind (the kind needed to escape from an angry mob, say), a cloaking shield (the kind needed to hide from an angry mob, perhaps), and a decelerator cannon (the kind needed to slow that mob down till you're sure you've gotten away). These abilities, plus a devastating Gatling gun in its exo-suit mode, make him a force to be reckoned with on the battlefield, which may be why the Autobots keep him around, despite it all.

Toys
Generation 1

- Circuit (Action Master, 1991)
- Accessories: Supersonic Racing Car/exo-suit
- Circuit is a redeco of Axer, sold only in European markets. As an Action Master, he cannot transform, but does have evidence of an alternate mode, possibly some kind of offroad buggy. He comes with a Formula 1 vehicle that transforms into a battle exo-suit. Both Circuit and the exo-suit are compatible with other Action Masters, vehicles and accessories.
- His placement of the cannon on his exo-suit is really phallic.
Timelines

- Circuit (Deluxe, 2012?)
- Accessories: Engine
- A redeco of the 2010 Transformers series Axor (itself a retooling of Revenge of the Fallen Lockdown), Timelines Circuit transforms into an amalgam of a 1980s Corvette and a 1960s Cougar, with lots of spikes and a cow-catcher on his bumper. The cylinders inside his thighs move as his lower legs rotate, and pneumatic cylinders extend as the axe that makes up his right hand is deployed. Circuits's arm-mounted hot rod engine weapon can be removed and can be replaced by Revenge of the Fallen Deluxe Ratchet's weapon. In return, Circuit's engine can be mounted on Ratchet's roof, but not attached to his arm.
- Circuit is one of the first six Transformers Collectors' Club exclusive figures to be offered via the Figure Subscription Service in 2012.
Notes
- The head of Circuit's Action Master toy has partially reversed colours when compared to the packaging art - the art shows a red face and a yellow racing-style helmet, but the toy leaves the face unpainted and instead paints a chin detail red.
