Okay! We got ourselves a title and a summary for this manga!
"Return! The Most Evil Duo"On Cybertron, Lockdown has captured Ultra Magnus and plans to dismantle him for parts, much to the annoyance of Runamuck who'd rather he didn't do that stuff in one of his favorite hang-out spots. He's further bothered by Runabout blowing stuff up, though it turns out his bomb-loving partner isn't just having fun: the explosions are caused by Autobots Override, Dogfight and Ricochet who have tripped some remote mines on their way to rescue Magnus. Runamuck takes Lockdown's Insecticons and heads out to fight the intruders, leaving Lockdown with Ultra Magnus... who then escapes his bonds, having merely faked being restrained. Before he can battle his captor, the other Autobots arrive, having made short work of Runamuck and Runabout, and Ricochet defeats the Decepticons with a powerful blast from Dogfight's gun mode. To Magnus's shock, the cocky Dogfight then tells him to clean up their mess.
Things haven't been a complete loss for Runamuck and Runabout, however, who are more competent than most think and have acquired a certain component during the conflict. Some time later they deliver the part to Bloody Knock Out, allowing him to finish his top secret project—the creation of Nemesis Prime.
