Thunderblast knows that the weakest part of any Autobot is his obnoxious sense of nobility. They're constantly rushing to the rescue, and every last one of them would sooner scrap a basket of Antilian bumble-puppies than blast a female as pretty as she is. She uses that fact to her full advantage; more than one Autobot has fallen first for her charms, and then to her plasma torpedos. As an agent working on earth for Starscream, she knows better than to trust any Decepticon, but she finds a kindred spirit in the con-man Sideways.
Brimstone likes the simple things - food, flying, trashing Autobots. He leaves stuff like thinking, planning and noticing what's going on in the world around him to his pal Undermine, which is just as well because that tiny, little head of his contains a badly undersized CPU. Still, being dumb doesn't make Brimstone any less dangerous. In flight, he is totally silent, and his diamond-edged vanadium wing blades can pierce even the toughest armor.
Crosswise is an ancient bounty hunter tricked centuries ago into following a target to Earth, where he was captured and sealed into the side of a glacier in the Alaskan wilderness. Gruff, sarcastic, and always spoiling for a fight, he isn't above resorting to dirty tricks to take down an enemy. Though he rarel works without getting paid, he also has a strong sense of right and wrong, and when he hears about the danger to Cybertron, he is only too glad to sign on with Optimus Prime and the Autobots.
A con man from the day he first came online, Sidways is a 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 intentions; at least long enough to jam a hidden blade through their anterior power units.
Snarl is master of the darkness, 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.
