Combaticons

Onslaught	Combaticon Commander Alt Mode - Missile Transport Flatbed Truck Onslaught is what you'd call the "hands-off" type. He doesn't enjoy getting his mits dirty, but instead prefers the thrill of designing battle plans, strategies, and tactics, and then watching his Combaticon soldiers carry them out. While he typically crafts his strategies to exclude his direct involvement, Onslaught is no coward. When required, he will engage in battle with strength, cunning and earthquaking fury. This darker, more brutish side of Onslaught might lead some Decepticons into thinking he has a secret blood-lust stashed away in his circuits. But truth be told, he's really just ticked off that his plans didn't work out the way they were supposed to.
Brawl	Combaticon Ground Assault Alt Mode - Leopard 1 Main Battle Tank If Brawl's on the battlefield and you can't hear him coming, it's time to check your audio receptors, because chances are you've gone deaf. Brawl's main distinguishing characteristic is VOLUME. No matter if he's talking, moving, or fighting you're sure to hear him doing it, as is anyone else in the county. As if that wasn't enough, he is also a ball of barely contained rage and violence with a hair-trigger temper. This makes him a force to be reckoned with on the battlefield.
Blast Off	Combaticon Space Warrior Alt Mode - Space Shuttle Blast Off is literally and figuratively above your average Cybertronian riff-raff. The other Combaticons could completely forget he's up here, orbiting so far above the Earth, distant and alone... with only the cold, empty void for company... and he couldn't care less. No, certainly not. Lesser robots could hardly understand the joy... yes, thats it, the joy, he finds in efficiently and remorselessly annihilating targets from such a great distance. Blast Off... Blast Off is quite happy with his superior position, yes, quite happy and... and quite alone.
Swindle	Combaticon Munitions Expert Alt Mode - FMC XR311 Combat Support Vehicle Capitalist first, Decepticon second, Swindle is a con-man, an opportunist, a hustler—or as he would put it, an entrepreneur. Unlike his fellow Combaticons, the Autobot-Decepticon war is to him merely an opportunity for networking, cutting deals, and making profit. He's an expert on all manner of weaponry and their market prices, and he prides himself on being able to sell anything to pretty much anybody. All he needs is a smile.
Vortex	Combaticon Interrogation Alt Mode - Sikorsky UH-60 Black Hawk Helicopter In a past life, it is very possible that Vortex was a roller coaster of some sort. He is the interrogator of the Decepticons, and his favorite method of divulging secrets from trembling Autobots is to take them on Mr. Vortex's Wild Ride. Laughing like a maniac, Vortex will treat Autobots held hostage within his cargo hold to a psychotic helicopter ride of twists, turns and near-death experiences. Then, once he has learned everything they have to tell: kerplop!

Constructicons

Scrapper	Alt Mode - Front End Loader Scrapper is the leader of the Constructicons. While the other Constructicons put their masterpieces together, Scrapper is the one who designs everything for them. His designs are among the best in Transformer history, however, Scrapper is a modest Decepticon who quickly shrugs off the praise he receives.Though modest, Scrapper is still a total nutcase. One of his favorite artistic liberties with his designs involves taking living Autobots and using them as raw materials.
Hook	Alt Mode - Crane The snob of the Constructicons, Hook considers himself an artist. He looks upon the rest of the Decepticons almost as peasants, beneath him to a degree. Though full of himself, Hook is a master craftsman, having truly earned his insufferable ego. His high standards that he holds himself and others to means he takes extra care to ensure even the most simple of jobs is completed to the nth degree of perfection.
Bonecrusher	Alt Mode - Bulldozer Bonecrusher finds beauty in rubble-strewn wastelands and longs to transform pretty much any location he happens across into one. Moreover, he makes demolition into a wild performance art. He loves to show off his destructive talents for his fellow Decepticons. Deep down, his destruction is really a perfectionism that cannot tolerate anything that he views as flawed, which includes the Autobots. Megatron values the fear and destruction Bonecrusher creates as much as the resources harvested in his wake.
Long Haul	Alt Mode - Dump Truck The problem, as Long Haul sees it, is that he gets all the work and very little of the excitement and the glory that goes with being a Decepticon. He knows his job is important; he'd just much rather be on the front lines fighting shoulder to shoulder with fellow warriors than moving supplies and building installations to make sure those warriors continue fighting.
Mixmaster	Alt Mode - Cement Mixer Nothing is safe. From raw ore to living robots, it all goes into Mixmaster's grisly drum where it's reduced, refined, and recombined into virtually any raw material the Decepticons need. Watching Mixmaster prepare a new batch of materials is like seeing some mad alchemist at work, giggling and cackling over his creations with evil glee.His fellow Decepticons suspect Mixmaster of having a few wires loose in his logic center, but they can't argue with the results.
Scavenger	Alt Mode - Trackhoe Scavenger wants so badly to be liked and needed, to feel like a useful and valuable member of his team. He's constantly excavating everywhere he goes in the attempt to find something of worth to please everyone and prove his value, but it's invariably just some piece of garbage or scrap he excitedly finds, and that just reinforces their opinion of his worthlessness. If it wasn't for his shovel's unique ability to detect needed materials, Megatron and the others would likely have dumped the poor scrub long ago.

Predacons

Razorclaw	Predacon Commander Alt Mode - Lion Know that when the Predacons are on the hunt, their leader Razorclaw is all business. Every drop of fuel in his system and every thought in his processor are dedicated to the task at hand, and he often lies in wait, completely motionless, for long stretches of time. Fools confuse this for laziness. Many of them have become his prey.
Divebomb	Alt Mode - Golden Eagle Divebomb's a cheery sort in general, almost always in a good mood, but nothing makes him downright giddy as a child on Christmas morning as having so many targets to pick and choose from that he doesn't know where to start destroying. Just about the only thing that ever puts him in a bad mood is having to give up his independence and combine with his teammates.
Headstrong	Alt Mode - Rhinoceros You can tell Headstrong that a three-foot-thick steel tank is full of dangerously radioactive waste, but it won't do a lick of good if he thinks you've hidden the energon goodies in it. He'll attack it with his unbreakable ramming head and acid-dripping horn until he's conclusively proven wrong, then retreat with his well-earned wounds to suck his thumb, still convinced deep in his tiny brain that somebody had tricked him.
Rampage	Alt Mode - Tiger Rampage is a bundle of overenergetic, destructive fury. He has difficulty thinking or talking for more than a short time without bursting into a wild rage and smashing everything around him. The blatant trail of wreckage makes it easy to follow him anywhere. The only thing that really calms him down is television. Generally the more mindless and stupid the programming, the more enraptured and entranced he becomes. Rampage can watch music videos for hours and hours without twitching a circuit.
Tantrum	Alt Mode - Bull Tantrum is loads of fun. He's all violence and no patience. Give him a can of Kremzeek™ energy drink with the tab pulled off, and he'll quickly devolve through frustration to crazed screaming to smashing the poor can to a splattered soup of oily drink and metal shavings. Such outbursts are common, and they usually end with a pile of smoking rubble, and Tantrum in the middle, with a happy, smiling face, the calmest and coolest of Decepticons, for a very short while, until next time the fit takes him.

Stunticons

Motormaster	Alt Mode - Kenworth K100 Aerodyne Sleeper Semi When Motormaster booms out orders in his hollow, bottomless-deep voice of doom, his Stunticon soldiers listen in very real fear. A cold and brutal tyrant, without an ounce of mercy or care for any lesser being, he considers himself the true "King of the Road." He longs to one day prove his claim by destroying Optimus Prime in a head-on collision, though he fears that someone else might kill Prime before he can. His fellow Stunticons hate him, but are too terrified of him to dare disobey his orders.
Breakdown	Alt Mode - Lambourghini Countach Sports Car Breakdown has an acute case of paranoia. He genuinely believes that things, both living and inanimate, are watching him. Breakdown doesn't like to stand out in a crowd. He dreads being different and garnering attention. At times, he almost wishes he was a human so he could just disappear and no one would notice. Needless to say, he and Red Alert would be energon drinking buddies.
Dead End	Alt Mode - Porsche 928 Sports Car Dead End knows that exsistance is pointless. Everything is going to end sooner or later, so whats the point? Despite this deep knowledge of the dark, inevitable pointlessness of existence, he spends an inordinate amount of time polishing and primping himself. This is something the other Decepticons are sure to tease him about whenever they get the chance, which only depresses him more. If you can actually motivate him to fight, he's a fearless warrior and actually cheers up a little, since trying to save his own life can momentarily distract him from how ultimately brief and pointless it is, the hard trick is getting him motivated in the first place, since in the end we're all doomed.
Dragstrip	Alt Mode - Tyrell P-34 Six-Wheeler Racer Drag Strip has never heard of the term "graceful in victory". He doesn't just like to win, he loves it. Drag Strip would sooner die a miserable death than ever sacrifice a victory, as he thrives on the bragging rights which accompany first place. He can't keep himself from stroking his own ego and bragging about his accomplishments in excruciating detail.
Wildrider	Alt Mode - Ferrari 308 GTB Sports Car What Fireflight does for air travel Wildrider does for the roadways. The difference is that the Aerialbot honestly means no harm and this insanely wild-riding Stunticon most definitely does. Some of his Decepticon comrades suspect him of playing insane to enhance his street cred, but those who have come to know him the best realize that it's no act. Wildrider really is as crazy as they come and a very real danger to anything on the road with him. Even his fellow Stunticons are wary of driving anywhere near him.

Terrorcons

Hun-Gurrr	Alt Mode - Two-Headed Dragon Hun-Gurrr is the leader of the Terrorcons and would be quite the model Decepticon and military strategist if he could just stop stuffing his two mouths. Hun-Gurrr is a terrible glutton, constantly filling his stomach with as much energy and materials as he can find. He only ever stops his insatiable feeding frenzies to fulfill his other desire: wanton destruction. In this capacity he is quite adept as a military leader, although his underlings are sometimes unable to understand his commands when Hun-Gurrr has stuffed his face(s) full of fallen Autobots.
Rippersnapper	Alt Mode - Bi-Pedal Shark Beast Rippersnapper has a massive inferiority complex; so he takes it out on just about everything else he deems inferior: animals, people, Autobots (Especially Autobots). Ultimately though, all these inferior traits he finds in others are just reflections of the traits he finds inferior in himself. He especially hates the odor of carbon-based lifeforms.
Blot	Alt Mode - Slaad Blot is the most vile and disgusting Transformer ever assembled. He oozes fluids of questionable nature from various joints on his frame, and has a rank odor that usually keeps foes and allies far away from him. Naturally, all this scorn and insult has given the less-than-smart Blot quite the inferiority complex. Stuck with a hygiene problem he can't control and a central processor a few bytes too small, Blot is both unable to solve the problems of his own stench and talk back to the insulting comments from his peers. Brutish and slow-witted, Blot is the classic dumb bully to those who don't give him respect.
Cutthroat	Alt Mode - Wyvern While most Decepticons enjoy trashing Autobots, Cutthroat revels in it. He'll tear a mech to pieces with his bare claws in his bloodthirsty zeal, showing not one iota of mercy. His fighting is so barbaric that it even disturbs other Decepticons; especially considering how much energy he wastes in his frenzies. Still, none of his peers are brave enough to mention anything to Cutthroat; for fear that he'll turn his insatiable bloodlust on them.
Sinnertwin	Alt Mode - Two-Headed Canine Like his fellow Terrorcons, Sinnertwin is a horrific insult to nature itself. Sinnertwin frequently patrols the Terrorcons' lair with the hope of finding anything unfortunate enough to be alive in his presence. Then comes the killing, and what with his multiple heads and sadistic nature, this is not something one would like to witness. Ironically, he's terrified of small creatures.
