Dear, Vector Prime.
Are there any other Cybertronians named "Transit" besides Primax, Uniend and Tyran?
Dear Bus Busybody,
Of course, but they're mostly alike. Transit is little more than a low-level thug, rarely involved in matters of consequence. On Earth, he likes to hide in populated areas, where the threat of collateral damage is enough to keep Autobots from picking a fight with him.
Even amongst the Decepticons, Transit is one of the most sadistic of them all. When approaching a traffic light, he will deliberately slow down just enough for it to change to red. At a bus stop, he'll surreptitiously angle his rear-view mirrors so the driver can't see people running to the doors before they close. He swaps out his route number and destination when in motion. He declines most contactless payments. He drops most luggage from his compartment. Once a month or so, he'll pretend to break down for no reason at all. And worst of all, he isn't wheelchair accessible. There is simply nothing in life that brings Transit greater satisfaction than making people late, and so despite what he may report to the Decepticon leadership, Transit is such a miserably ineffective soldier in the "war on cars" that he may as well be a double agent.
The one incarnation of Transit I can think of who ever did anything of note did so entirely involuntarily. One of the largest Maximals ever sparked, Transit ferried Micromasters and proto-formers around Damaxus, together with his driver, Arrowbolt. With budget slashes, a standard Class-H energon ration wasn't enough to power Transit's frame, and so he was stuck in vehicle mode indefinitely—not unlike many of the Builders.
Now, Damaxus, as you may know, was one of the first cities to be overrun by Vehicons, with most of the population just trying to go about their lives in the unstable climate of the time when the infection began to spread. Transit was on his usual route, when his passengers saw the chaos begin to unfold outside the windows. Fleeing from the drones, a Cyberdroid, Omega, ran alongside the bus, banging on the door—and Arrowbolt ignored the protests of Socket, one of the Micromasters on board, to stop and let him in. One of the motorcycle drones was right behind him, and it was only the quick action of Major Mayhem, a Predacon in one of the front seats, that stopped the Vehicon getting aboard. Major asked Arrowbolt to take Socket's advice: to not stop again for any reason.
Transit's energon-starved chassis turned out to be a blessing in disguise, as his body had such poor internal conductivity that the virus wasn't immediately transmitted to his spark from his exterior. He thundered through the growing mob, as the Vehicons pounded on his windows and piled onto his roof. Major Mayhem ordered everyone to barricade the entrances as the Vehicons began to break in, and they were able to fend off the attackers for a time—but in the claustrophobic interior, their hostility soon turned to the other passengers.
The other riders were Rockbuster and Bound Rogue, both Maximals; and Yardarm, a Decepticon laborer who bristled at the idea of taking orders from a Predacon. Making matters worse, Rockbuster suggested that the Vehicons were the Builders' doing, blaming Socket and Yardarm. From the driver's seat, Arrowbolt tried to keep the peace, but Major Mayhem accused her of condescension and cowardice he saw as typical in Maximals—which in turn led Bound Rogue to brand him a bigot.
Although Rockbuster's hardwired Claw Buster gun was their most effective weapon against the Vehicons, he quickly ran out of energon. Bound Rogue pointed out that Socket was still practically fully-fuelled, but the Micromaster refused to share some of her own so Rockbuster could reload. That was enough for Rockbuster to finally snap; he turned on Socket, crushing the Micromaster's body in his claw. At that point, however, an ethereal purple light filled the bus—where Omega had been sitting, there was now a tank drone. With Yardarm preoccupied tackling Rockbuster in the aisle, it plunged a claw into the floor. Major Mayhem blasted the Vehicon, but it was too late: the effects of the virus began to take over Transit, reformatting his body into another mindless killing machine… with his passengers still inside.
