For most of his life, Runamuck served as a spy and courier for Megatron, carrying messages to Decepticon warriors behind enemy lines. Since his leader's disappearance, though, Runamuck has been pretty bored. Too many Autobots around meant he couldn't get away with much. But now, with the Autobots forced into hiding on Earth, he's having the time of his life tormenting them by striking at vulnerable targets in front of a lot of human witnesses, where the Autobots can't counterattack.
Despite the evacuation of Cybertron, and the incredible danger presented by the black hole, many of the bravest craziest or most foolish stayed behind. Buzzsaw is one of the crazies, a dangerous rogue from the Decepticons old guard who intends to hoard as much of the planet's Energon as he can for himself, hoping to gain enough power to destroy the Autobots upon their return! For now, he is content to lurk in the abandoned cities of Cybertron, practicing his marksmanship by blowing the tops off the old Energon Towers.
A former race champion, Blurr retired years ago and has since made a career coaching younger speedsters in the subleties of racing. He is a touch teacher, with a gruff personality that often comes across as bad-tempered to those who don't know him. Long-time students of his know, however, that his demanding temperament hides a gentle Spark. He is tough on those who come to him for training because he takes their successes and failures personally, and he recquires no less of his students - and himself - than their best.
Tough as nails and patient as a mountain Longrack just wants to fulfill his mission to repair as much of the damage already done to Cybertron as possible. He doesn't like to fight, but that doesn't mean he's not good at it. If Runamuck and the other Decepticons are spoiling for a confrontation, Longrack is more than happy to introduce them to his powerful Crushsteel Punch.
Snarl is master of the darkest, most wild places on the Jungle Planet, and it is through his cunning that the Jungle Planet rebels have survived long enough to team up with their new Autobot allies. He is a robot of few words, preferring constant action to hiding and resting. Despite this, he is a clever fighter and a careful planner, never putting his soldiers at unnecessary risk, and never leaving a 'bot behind to be tortured by his sworn enemy Scourge.
A con man from the day he first came online, Sideways is master of deception, mixing just enough truth into his lies to keep both his enemies and his allies off guard. His tongue is as sharp as his sword, always ready with another trick of language to keep his marks guessing at his true intention; at least long enough to jam a hidden blade through their anterior power units.
