From Shows like Avengers Earth's Mightiest Heroes, and Transformers Prime. Here they are: *Peter Cullen voices Optimus Prime; leader of the autobots *Leonard Nimoy voices Sentinel Prime; former leader and reformed autobot *Colleen O'Shaughnessey voices Override; Optimus Prime's female second in command who cares for him and is also the autobot leader’s love interest. *Peter Renaday voices Ultra Magnus; leader of a group of autobots who escaped the Ark before it crashed onto the moon and guarded a hidden air field in the south eastern part of the USA that the aerielbots reside on. Now he is back and ready to help Optimus fight the decepticons once again. *James Remar voices Sideswipe *Brian Bloom voices Trailbreaker; a black chevrolete avelanche and brother of the late Ironhide *Chris Cox voices Hound *Bumblebee *Robert Foxworth voices Ratchet *Sunstreaker; an autobot killed by Skyquake at the beginning of the film. *Neil Ross voices Kup *Sumalle Montano voices Moonracer *Bruce Greenwood voices Springer *Phil LaMarr voices Windcharger; second in command in Ultra Magnus' group of autobots *Jeffrey Combs voices Powerglide *Aerielbots; a special group of autobots that Ultra Magnus and his crew were defending in the Little Rock Airfield. They all together combine into Superion. **James Avery voices Silverbolt; the leader of the Aerielbots **James Horan voices Fireflight **Slingshot **Skydive **Sky Shadow; the silent member of the aerielbots who is also a ninja *Michael Clarke Duncan would have been the perfect candidate to voice Omega Supreme (a massive autobot who transforms into the Ark itself) but unfortunately he died on September 3rd 2012 due to a 2 month heart which leaves us puzzled on who would fit as the best fitting deep voice of the character, Fortunately Jack Angel, the original voice of Omega Supreme is more than happy to reprise his role as the character. and finally the decepticons *Lance Henriksen voices Skyquake; the main villain in the film and leader of a hidden legion of Decepticons called the Predators, who takes charge at leading the decepticons to victory by having them wipe out all human military forces claiming that they're the reason their race is dying out. As Skyquake now transforms into a B-1 Bomber jet and posesses the power of the allspark, he will stop at nothing until the decepticons are rid of all human military resistance and ensures the survival of the cybertronian race. *Steven Jay Blum voices Blitzwing; a decepticon triplechanger who turns into an F-35 jet and a tank. Blitzwing hid in the mountains with the other elite members of the decepticon army awaiting orders from Skyquake. He is much of a war monger who is always looking for enemies to kill in battle. *Robin Atkin Downes voices Cyclonus; an elite member of the decepticons who is skilled in combat in ways of sword fighting and shooting. After the decepticons enslaved the humans who discovered the Ark, he and the rest of Skyquake's forces took refuge in the mountains of Montana until Skyquake returned as leader and carried out his orders by helping other decepticons take out every satillite in Earth's orbit to keep N.E.S.T. from tracking their position and turn every military vehicle in the bases they attack into lethal killing machines called the Combaticons. **Kim Mai Guest voices Ratbat; Cyclonus' pet bat and partner. Ratbat is originally a minion of Soundwave but because the decepticon was killed by Bumblebee in Dark of the Moon, the decepticon will act as Cyclonus’ minion. *Brad Garrett voices Octane; an arrogant decepticon triple changer who enjoys battling his enemies as well as having to draw them out by attacking innocent people in order to do so. *Miguel Ferrer voices Scourge; an elite member of the decepticons who assists Skyquake in the final battle. *John Dimaggio also voices Dirge *Mark Rolston voices Thrust *Combaticons; drones created by the decepticons using energon they extracted from the allspark fragments they found and shot into many military vehicles to help terminate every soldier in the bases they are in.
