Runabout is not the brains of the Battlechargers (they’re both pretty much dim-bulbs), but he is much calmer and certainly more articulate than Runamuck, and his presence helps keep the latter’s cross-wired mind on task. That said, Runabout usually joins in with whatever mad ideas Runamuck comes up with, just to keep from being bored. Runabout is very susceptible to boredom.
Besides, Runabout loves a good wreck just as well as his crazy comrade, but it’s not because he craves to create wreckage—he simply wishes to destroy, and enjoys the spectacle of chaos and big fiery explosions. To help create these he has a particle beam rifle that shoots a stream of heavy and energetic neutrons. Unfortunately, he craves destruction so much that it continually distracts him from his assigned duties.
Runabout is a little faster than Runamuck, with a 185 MPH top speed, but can only go about 550 miles. He is equally able to transform quickly, taking about .4 seconds to do so. Also like his partner, he is not averse to breaking windows or draping cylinder-wiping paper over the enemy base, or other puerile acts of vandalism. But he uses bigger words when doing so.
? BCE (Before the Great War)
Megatron Origin 3 – Runabout is seen as one of the gladiators listening to Megatron’s speech about forming the Decepticons.
After Megatron’s speech at the assembled gladiators, the Autobots attack, imprisoning many of the gladiators. Runabout ends up in a cell in the Kaon Autobot Security HQ with Megatron and Starscream. Right after Starscream talks to a guard, Megatron screams traitor, and orders Starscream killed. Before the job can be done, Starscream is removed from the cell.
