Transformers Prime

The Autobots investigate the return of the Decepticons and must account for a group of young humans who become involved in their eons-old conflict.

When a weak life signal is received from Cliffjumper, the Autobots roll out but are met by Megatron, who has obtained powerful Dark Energon.

Bulkhead is on a mission to rescue Agent Fowler, who has been kidnapped by the Decepticons. Complications arise when Miko secretly tags along.

Megatron uses the Dark Energon to summon an army of undead warriors to battle Optimus, while the other Autobots launch a high-stakes rescue operation.

The ultimate showdown unfolds in Earth's orbit as the Decepticons, aided by Megatron's undead army, do battle with the Autobots.

While Optimus Prime and Bumblebee square off against Skyquake, Starscream encounters challenges to his leadership at every turn.

Bulkhead, Bumblebee and Ratchet scramble to eliminate a swarm of Scraplets that have invaded Autobot base while Optimus patrols in the Arctic.

Bulkhead eagerly anticipates a visit from his old friend Wheeljack, but when his buddy arrives things are not as they seem.

The Autobots help Agent Fowler transport a hazardous explosive device, but this time they come under attack from more than just the Decepticons.

Miko and Bulkhead head to Greece on a field trip to recover an Energon Harvester, and class is in session for new Decepticons Knock Out and Breakdown.

Jack convinces Bumblebee to help him win a street race, but the action speeds out of control with the arrival of Knock Out.

Arcee takes Jack along on a seemingly routine mission, but she encounters an archenemy and must face her deepest fears.

Optimus Prime becomes infected with a Decepticon plague, and Arcee and Bumblebee must sneak aboard the Decepticon warship to find the cure.

Megatron remains a fixture inside Bumblebee's mind and manipulates his actions back at Autobot base.

During a GroundBridge malfunction, the kids find themselves trapped inside an alternate dimension with a reanimated Skyquake.

The Autobots roll out to rescue Breakdown, the Decepticon who has been abducted by Silas and the sinister agents of MECH.

Airachnid negotiates a deal with Silas to use MECH to exact revenge against Arcee and Jack.

Arcee and Bulkhead find their efforts to stop a Decepticon mission hampered by a magnetic device.

When the Autobots, along with Jack and Miko, fall victim to an Energon mine cave-in, they find themselves trapped with Starscream and Megatron.

Airachnid and Starscream team up to retrieve a weapon, but when Starscream is captured, he reveals that he would rather team up with the Autobots.

When Bulkhead's brain is accidently endowed with the secret formula for synthetic Energon, he becomes a recluse while the Decepticons hunt him down.

Ratchet injects himself with synthetic Energon, which makes him a menace to the Decepticons, but also to the Autobots and to himself.

Megatron's attempt to fulfill an ancient Cybertronian prophecy results in a hero becoming mortally wounded, then leads to a long-awaited rematch.

When Earth becomes plagued by natural disasters, the Autobots come to the horrible realization that Dark Energon is the source of the bizarre events.

Facing the greatest threat to Earth yet, the Autobots team with an unexpected ally.

As the Autobots do battle at the Earth's core, Jack learns more about Optimus's past on Cybertron.
