Team Prime wages war against the Decepticon citadel.
Transformers: Prime, also known as Transformers: Prime – The Animated Series, is an computer-animated TV series based on the Transformers. Team Prime lives on Earth as a pre-emptive measure against the return of the Decepticons. Autobot Central Command is located in a converted missile silo in Nevada. The Autobots have taken three human teens under their protection after their association with the Autobots put them in danger from the Decepticons. Megatron returns having discovered Dark Energon, but is injured, with Starscream taking command in his absence. There is also comic books based on Transformer Prime, and a video game is set to release in Fall 2012. Season 3 is preparing.
After Starscream’s armada fails to apprehend Wheeljack, Shockwave introduces Predaking, an enormous reptilian creature created in Shockwave’s laboratory and specially bred to hunt down Autobots. Meanwhile, high-ranking Autobot general Ultra Magnus arrives on Earth and sets about reuniting the scattered members of Team Prime.
As the Autobots try to re-group, Shockwave arrives in Darkmount after years of isolation on Cybertron, and is welcomed back into the Decepticon ranks. Wheeljack escapes from Darkmount and sets off to rendezvous with Bulkhead and Miko, unaware that Starscream has planted a tracking device on him.
With their base destroyed, the Autobots and their human companions have separated and went into hiding, while the Decepticons settle into their new fortress, Darkmount, and repel a military assault. Meanwhile, Smokescreen finds Optimus Prime, still alive but badly damaged and close to death, in the wreckage of the Autobot base.
The Autobots are forced to surrender all their weapons and the Keys in exchange for the humans. Megatron then puts the Omega Lock to use, initially to reform the war-torn Cybertron, but then also to convert Earth into a new metal planet, at which point Optimus is forced to destroy the Omega Lock. The Autobots retreat back to Earth, but the Decepticons have discovered the Autobot base’s location, as a new dark citadel had been created in front of it.
