Transformers Energon

It's been 10 years since Megatron disappeared and the Autobots and Decepticons now work side by side with humans to harvest Energon. But the Autobots face a new threat: attacks by Transformers known as Terrorcons.

After analyzing the Terrorcon threat, the Autobots decide to send away all the civilians living in the energon mining bases.

Scorponok captures Tidal Wave and makes him follow his orders so that they can revive Megatron with energon.

Tidal Wave sees Megatron's sword.

Super Optimus Prime emerges to find his team searching for energon.

Megatron is alive again and forces Scorponok to serve him, but Scorponok is loyal to only one master Alpha Q.

Megatron launches his first Energon raid since his resurrection.

Alpha Q has revived Starscream, who's mission is to destroy Optimus Prime, so as to regain a new body.

The Autobots go into the asteroid belt to see what is going on after seeing something on radar, and find parts of Unicron.

A new Autobot weapon is revealed that unleashes vast destruction to the Decepticons.

Alpha Q prepares to bring Unicron to life, while yet another Energon Tower is secured into place.

Alpha Q is not ready to let Earth go without a fight, and sends a group of stealth Terrorcons, named Command Ravage and Blackout.

Megatron forces Demolishor to divulge the Autobots' secret of finding energon: Kicker.

Megatron has taken yet another plan, to create three meteors from Unicron and propel them at Earth before the energon grid has been completed, which he feels will "strike fear in Optimus Prime."

While Snow Cat tests his power against the Energon Grid by sending frozen asteroids, Megatron decides to go after Alpha Q instead of Earth after finding a Terrorcon spy.

Optimus reveals their mission is twofold: they are also going to destroy Unicron, and they prepare to set up a space bridge.

The Autobots face a new threat: for Demolisher is revived in a new Power, who is tougher than ever.

The autobots continue on their journey and intercept a decepticon warp signal which turns out to be Rodimus's ship. Rodimus asks permission to aboard and Optimus obliges.

The autobots continue their planning on taking out Unicron.

Unicron's arrival causes the Decepticons on Cybertron to rebel, while Kicker learns the truth about Alpha Q.

Megatron commands Shockblast to lead an assault on Cybertron to take out the Energon towers, in order to allow Unicron to "feed" on Cybertron.
