Airazor - She's calm and confident, but also adventurous and brave, with a healthy supply of dry humor. Her aerial skill in either mode, incredibly sharp eyesight and steady aim make her a dangerous opponent. She is especially close to Tigatron, always trying to get him to move past his solitary instincts and spend more time with his fellow Maximals. She shares his love for the beautiful planet on which the Maximals are stranded, and it is on this planet where their destiny will be forever intertwined.

Optimus Primal - Though he does have a penchant for stuffy speeches, Optimus Primal is much more down-to-Cybertron than his legendary namesake. He is committed to the Maximal codes of honor and moral judgment, but he does view them with some irreverence, and is not above finding loopholes or administering unorthodox solutions if necessary. ("Sometimes, crazy works", he says.) He is eternally loyal to his friends and respectful to his enemies. He is brave and selfless in battle. However, he is so committed to helping others that he can withdraw into a deep depression when he feels he has let them down. This is the only time he is self-absorbed.

Cheetor - A young Maximal full to bursting with energy and exuberance, Cheetor is always ready to leap into action at a moment's notice. And, much to his colleagues' chagrin, he often does so without a moment's consideration or forethought. Nobody can fault his motives, just his methods.

Rattrap - He's sarcastic, irreverent, and rude. Plus he smells (why he smells is a mystery). He's also not the most trusting or forgiving sort, so he's not the best choice to take on a diplomatic run. He'd sooner shoot a Predacon or Decepticon than talk to them.

Rhinox - Rhinox is of a rare breed—he's incredibly tech savvy, but mystically inclined... without coming off as a burnt-out technohippie. He's quick and decisive in a crisis, with spectacular results, but is slow and steady. He loves to sniff the flowers. A behind-the-scenes charismatic and an on-his-feet strategist, he could lead the Maximals if he wanted to, but he doesn't.

Dinobot - Dinobot is a proud, honorable, and often abrasive warrior, a former Predacon turned Maximal, with a Velociraptor beast mode, known for his strict code of ethics and frequent clashes with Rattrap, even while developing a strange rivalry/friendship.

Tigatron - A loner who is more connected to the Earth than any other Beast Warrior, he enjoys the planet's natural beauty and is often concerned about the damage that the Transformers' battle is doing to it. Scout, infiltrator, and sometimes programming guru, Tigatron has filled a variety of roles for the Maximals.

Megatron (BW) - Megatron is the ruthlessly pragmatic leader of the Darksyders. He is willing to sacrifice his own teammates to further his own agenda to conquer Cybertron. It is fitting that he has proven to be much more strategic and manipulative than his namesake, in which in his plans to succeed, he plays everyone in order to gain his victory. Whatever opportunity he has, Megatron takes it if it benefits him, like a chance to escape during the transwarp sequence of the shuttle he is strapped to.

Waspinator - Arrogant, Mocking, Brutal he was not very kind, he was the perfect stereotype of the school bully. He also had a cruel humor as seen at several ocassion when he senses taking to Bumblebee.

Terrorsaur - an obnoxious, loud-mouthed thug who no one likes. But he also happens to be a coolly-effective warrior on the battlefield, which is the only reason why his Decepticon comrades tolerate him. Of course, they'd never actually tell him he's a natural in the ways of combat.

Scorponok (BW) - He's often dumb, and he's always loyal to Megatron (surprisingly so, considering Megatron's other crew members), and of those two features, only the loyalty seems to be consistent. He tries to serve Megatron to the best of his abilities, but when Waspinator is able to outwit you, there's only so much you have to offer.

Tarantulas - He's the type of mad scientist who experiments on living beings, cackling in his trademarked laugh all the while, and then if things go wrong, happily eats what's left as his midday snack. The eating is what he was really looking forward to, anyway. It's this focused perversity that turns off even his fellow Predacons. Tarantulas's emotional detachment from their war also rubs his peers the wrong way. Fighting Maximals and following orders is just a required chore; his real passion is the unmentionable projects stashed in his "secret" lair.

Blackarachnia - A sultry femme fatale, Blackarachnia is smart, sly, and dangerous. She's got eight legs, and she knows how to use them.

Inferno (BW) - Inferno wholeheartedly believes that he is an ant and that Megatron is his queen. Unlike many Predacons, he has no personal ambitions or future plans; everything he does is for the good of the colony and his queen. Luckily for Inferno, many of the tasks his queen assigns him involve burning things—and he likes burning things. Keeping with his ant mentality, Inferno has absolutely no regard for his own personal safety whatsoever. He is fanatically loyal to Megatron, and as such will use his heavy firepower and incredible strength full-on and take any task given of him, no matter how suicidal. And he'll do it laughing maniacally the entire time, for the glory of the colony.
