Runabout and Runamuck are two minor antagonists in the Transformers franchise, especially Generation One. They form the Battlechargers Decepticon sub-group.
In the cartoon, they were voiced by the late Roger Behr.
Runamuck has a small appearance in the third season episode "Chaos", riding Astrotrain and utilising the Decepticons' newly-discovered death crystal weapons. The Battlechargers' only full appearance was in "Ghosts in the Machine" where they, along with Dirge and Thrust, failed to prevent Scourge and Starscream's ghost from stealing one of Trypticon's eyes. Hiding from the wrath of Galvatron, they were left trapped inside Trypticon when Starscream stole it but managed to disable the giant robot and foil his plan to connect it to Unicron.
Runabout and Runamuck's involvement in the Wings Universe comics produced by the Transformers Collectors Club act as a sequel to the cartoon.
At some other time, the pair were hanging out with the equally-delinquent pair of Jetstorm and Deluge when a giant Autobot and his Quintesson cohort wandered into their territory. While Jetstorm and Deluge jumped the Autobot, Runabout and Runamuck tortured the Quintesson. But as Runamuck was pressing his foot down on the Quintesson's head, he surprised to learn just how strong his would-be victim's tentacles were. A short moment later, all four Decepticons were defeated, left brutally embarrassed.
At some point between various upgrades, the quick-transformation feature from Runamuck's frame was abandoned in order to boost his armament and resistance to harm. Both Battlechargers were also offered a flight mode but turned it down. Runamuck often forgot this final detail, and would jump off of buildings and cliffs in an effort to take to the air.
After having been absent from Cybertron for a very long time, Jhiaxus made a secret return. He enlisted Runabout and Runamuck in filling him in on what he had missed, and the pair gave him a very amusing, yet sufficiently informative, recollection of the events of the Battle of Autobot City and Cybertron's first contact with Nebulos. The information convinced Jhiaxus that this would be the perfect time to rebuild his Cybertronian Empire.The two Battlechargers were dispatched to find some personality components, and in the process discovered a stasis hibernation pod which opened to reveal Side Burn. They took the amnesiac Side Burn him back to Jhiaxus, after which they all headed to Nebulos, where Jhiaxus had Runamuck and Runabout kidnap. After they arrived on Qre, the pair engaged in some racing with Side Burn. When Side Burn's advances were rebuffed by Nightracer, Runamuck suggested giving her some space, but Side Burn followed Runabout's advice to follow her instead. The Battlechargers trailed behind him. Following Jhiaxus's defeat, Side Burn promised the pair leniency, and indeed after the pair returned to Earth with the Autobots, Hi-Q said he wouldn't press charges.
The Battlechargers were among the reinforcements brought to Earth by Megatron introduced in US #23. They were told to challenge Optimus Prime to a duel but preferred to instead go on the rampage across the country, defacing several famous monuments with graffiti. This brought them into conflict with Circuit Breaker, who attacked them with a giant robot made up from captive Autobots as they defaced the Statue of Liberty. The Battlechargers were defeated by the colossus and left deactivated as they crashed into the water.
The pair eventually returned as part of Shockwave's rebel Decepticon army, with which he planned to wrest control of the Earth Decepticons from Scorponok. Together, they attacked Scorponok's base but the rebellion didn't last long thanks to the intervention of the Autobots and all the Earth Transformers being transported to Cybertron to defend it from Unicron. Runamuck was killed during the battle. Runabout survived, only to be killed the following morning by a Cybertronian demon released during the battle.
Due to irreconcilable continuity with the main US run, Earthforce occurs in a slightly different timeline. That being said, it is possible some of the events did occur in a different way in the main timeline.
Marvel UK's Earthforce storyline offered an alternate timeline in which Runabout and Runamuck also joined up with Shockwave. During one early battle, Runabout almost killed Grimlock with a neutron cannon, only to be tricked into taking a step back to avoid being caught in the blast and falling off a cliff. They later battled the Stunticons Drag Strip and Dead End for possession of Megatron's global warming device, unaware it had already been rendered inert by Prowl. After the two Decepticon factions were united under the command of Soundwave and Starscream, Runabout and Runamuck joined Soundwave in a diversionary attack on the Autobot base while Starscream tried to hijack an oil tanker.
