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.
Fiction
IDW Generation 1 continuity

Circuit could be seen propping up the bar at the Blurr-run Maccadam's Old Oil House. Night and the City Once Cybertron got a proper comm-net going in the form of the Iacon Communication Service, he became a news reporter, first interviewing Starscream and Omega Supreme over the matter of a Metrotitan awakening in the former's presence and later reporting on an attack on Omega. The End of the Beginning of the World When Decepticons began rioting in the wake of Megatron's return, Circuit took to the streets to report on the chaos and was approached by Metalhawk, who wanted to use the comm-net to talk to the people of Iacon and quell the violence. The Verge Once Metalhawk was done with his speech, the reporter was pulled away to check out reports that Megatron had been broken out of prison. Before the Dawn
After an intense battle that ended with Megatron's defeat, Circuit witnessed Starscream declare himself leader of the NAIL population and banish all Autobots and Decepticons from Iacon. Heavy Is the Head Having left the Autobots, he and his cameraman Longtooth stayed in the city and continued their line of work, reporting the rise and fall of Scoop. Three Monologues
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.
- The placement of the cannon on his exo-suit is really phallic.
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.
