Salvo
Salvo is an autobot weapons specialist, desert warrior and demolitionist. One of the most feared autobots, aswell as a member of the Wreckers. Equipped with a Gas-Glass rocket launcher, mounted rockets, a semi-automatic laser rifle with burst rounds hat comes with a flamethrower feature, which fires a cybertronian variant of napalm he made himself and even a throwing axe. His armor is heavily built to withstand the toughest of onslaughts. Salvo is fearless in the face of adversity, with a "No bot left behind" attitude, he'll keep fighting even after he's out of ammo and until all his armor has been blown off and shredded.
Alt mode:

T72 Tank (but also equipped with a flamethrower)

(Salvo has the same voice as Soldier from Team Fortress 2 because reasons)

Stingfire
A genetic insecticon-predacon hybrid created by Shockwave, Stingfire is ferocious, aggressive, animalistic and downright voracious. He possesses strength that nearly rivals that of a Dinobot, can fire burning stingers from his wrists(robot mode) and abdomen(beast mode). He spits and/or regurgitates an oozing magma like substance from both his robot and beast mouths, which can melt through most substances, but if he carefully releases it, the substance cools down into a hard rock-like structure. Giving him the building abilities of an insecticon. He's gained a reputation of eating his victims alive, aswell as leading hoards of insecticon flyers into raids.
Alt-mode:

He transforms into a mutated version of a Japanese Killer Hornet.

(The last two are for BraedimusSupreme )

Ultimate Redvolt

The hyper-evolved version of the crimson electrical speedster, his speed has increased to such a rate, it exceeds lightspeed, capable of circling the largest of planets in only a few minutes. He posses enough electrical power to power the largest cities in the world(Earth). Ultimate Redvolt's sword Crimson Edge has changed into what is now Lightning Fang, which he can wield with such speed, he can deflect and slice apart rounds from automatic weapons with even the highest of firing rates. He can create several after images with his speed, and electrical attacks have no affect on him whatsoever.
Alt mode:

Cybertronian Star-cruiser. (Wheels flip open from below when he's on land and has a warp drive when in space)

Ultimate Astrosaurus
The hyper-evolved version of the Artillery and Cavalry Transport Predacon of the Autobot faction. He's nearly about the same height as Omega Supreme with his new, more humanoid appearance, which has also now heightened his speed, now making him move as quickly as Mach 5 in his dragon mode. He can create a powerful energy shield around himself that can fire lasers(similar to the Castle of Lions from the new Voltron series). His shoulder cannons have both a rapid fire and powerful laser function, and combined with his plasma breath, deal devastating damage. Ultimate Astrosaurus also possesses dart missiles which can be deployed from his shoulder pads and outer thighs.

His Alt-mode:

He transforms into a Starship that is about twice as small as the Nemesis, but is significantly faster, and surprisingly agile for its size.
