When Michael Bay's third installment hit theaters, it brought an unprecedented scale of robotic carnage to the screen. If you're wondering about the Transformers 3 cast, the film features a massive roster of cybertronian warriors. It blends classic fan-favorites with heavy-hitting newcomers on both sides of the allegiance line.
Finding a complete breakdown of every returning face alongside the new recruits can be tough. We've mapped out the entire cybertronian lineup. This guide covers every veteran Autobot and Decepticon returning for the final battle in Chicago, along with the vocal talents behind them.
The Autobot Roster: Returning Heroes and New Recruits
The Autobots return with heavier firepower, new vehicle modes, and high stakes. They face a devastating betrayal that shakes their leadership to its core.
Optimus Prime
Voiced once again by the legendary Peter Cullen, Optimus Prime anchors the entire franchise. In this film, he rocks his iconic Peterbilt semi-truck mode complete with a trailer that transforms into his flight gear. He carries a heavy burden as secrets from Cybertron's past come to light.
Bumblebee
Our favorite yellow Chevrolet Camaro stays by Sam Witwicky's side. While he doesn't speak through conventional human words, his radio snippets communicate his fierce loyalty. He remains the core scout and frontline fighter for the team.
Ironhide
Voiced by Jess Harnell, the rugged GMC TopKick weapons specialist returns to deliver heavy-duty offense. Ironhide's tactical expertise and aggressive posture make him an indispensable part of the core command group, though his fate takes a shocking turn early in the movie.
Ratchet
Voiced by Robert Foxworth, the reliable medic trades his classic look for a vibrant green and white Hummer H2 search-and-rescue vehicle mode. He coordinates field operations and medical triage when the fighting gets brutal.
Sideswipe
Voiced by James Remar, the silver Corvette Stingray concept car returns with his signature arm-blades and acrobatic combat style. He handles close-quarters skirmishes with cool precision.
Wheelie and Brains
Voiced by Tom Kenny and Reno Wilson respectively, these two diminutive former Decepticons turn scavengers provide comic relief. Wheelie rolls around in a remote-controlled monster truck mode, while Brains sticks close behind as his partner in crime.
New Autobot Additions
While veterans anchor the team, several major faces join the lineup for the third outing.
Sentinel Prime
Voiced by Leonard Nimoy, the former Autobot leader is discovered sleeping inside a crashed spacecraft on the moon. His rescue triggers the main conflict of the film, adding profound dramatic weight to the narrative.
Que (Wheeljack)
Voiced by George Coe, this eccentric inventor Autobot takes the form of a blue Mercedes-Benz E-Class. He supplies the human military with high-tech gadgets, including the grapple gloves used during the final act.
Dino (Mirage)
Voiced by the late Francesco Quinn, this sleek red Ferrari 458 Italia speaks with a thick Italian accent and wields deployable blade cables in combat.
The Wreckers (Leadfoot, Roadbuster, and Topspin)
This specialized Autobot sub-team transforms into heavily armored NASCAR Sprint Cup Chevrolet Impalas. They bring crude humor, heavy artillery, and abrasive attitudes to the battlefield. Leadfoot is voiced by John DiMaggio, and Roadbuster by Ron Bottitta.

The Decepticons return with a vengeance, executing a centuries-old conspiracy that puts Earth in mortal peril.
Megatron

Starscream
Voiced by Charles Adler, Megatron's treacherous second-in-command returns in his Lockheed Martin F-22 Raptor jet mode. He continues his usual cycle of sycophancy mixed with quiet ambition to usurp leadership.
Soundwave
Voiced by Frank Welker, the Decepticon communications officer takes on a sleek Mercedes-Benz SLS AMG civilian vehicle mode. He handles espionage and coordinates troop movements across the globe.
Laserbeak
Voiced by Keith Szarabajka, Soundwave's deadly minicon companion transforms into various technological forms, including a pink desktop printer and a flat-screen television, to infiltrate human installations.
Barricade
