Transformers: Animated

Sari Sumdac is coping with the newly discovered fact that she's a robot. Meanwhile, the Autobots on Earth are trying to figure out a way to warn the Autobots on Cybertron about the spy working for Megatron. Later, Megatron and Starscream find Omega Supreme and set a devastating plan in motion.

Things quickly descend from bad to worse for the Autobots when Detroit is menaced by new threats. Meanwhile, Ratchet remembers his first encounter with Omega Supreme and grows frustrated with his uselessness to the Autobots, all while Megatron and the Decepticons enact their plans.

The Autobots are given a triple blow when one of their own is critically damaged, another is overloading destructively and the third has become an assault weapon for Megatron.

Unaware that he is being followed by the Elite Guard, Wasp heads to Earth to take his revenge on Bumblebee.

When Sentinel Prime successfully captures fugitive Decepticons, Prowl becomes suspicious.

The Autobots and the Elite Guard pursue Wasp for their own agenda. However, Blackarachnia has Swoop capture Wasp in her latest attempt to rid herself of her organic half. This experiment goes awry and turns Wasp into Waspinator.

On Christmas Eve, Optimus Prime patrols the city in search of Soundwave. With Porter C. Powell selling Soundwave action figures, Optimus is paranoid that the real Soundwave is out there. When the Autobots drift off to sleep, they awake as full fledged humans. Now they must figure out what happened to them while dealing with a Decepticon onslaught.

It turns out that Soundwave has trapped the Autobots in a virtual reality. Now, Sari must free them before Soundwave completely turns them into Decepticons.

In an effort to speed up their return to Cybertron, Sentinel Prime has Jazz pilot the Elite Guard ship through a space storm. The storm's energies reactivate Swindle, who frees his fellow Decepticon prisoners, and the group goes on to take over the ship. Sentinel Prime sends a distress call to Optimus Prime, who uses the newly completed Space Bridge to TransWarp to the ship, where he helps fight back against the Decepticons.

A TransWarp accident with the Space Bridge sends Ratchet and Captain Fanzone to Cybertron, where Sentinel Prime has the planet on high alert. They soon end up stumbling upon a plot by Shockwave to steal Omega Supreme's Access Codes from Arcee.

The Autobots discover Omega Supreme's energy signal on the Moon. Rachet insists on going there right away to save him, but Prime refuses, knowing that they are too weak to fight Megatron. Ratchet, Sari and Professor Sumdac build flight boosters for Optimus to even the chances. Prowl tries to put the Allspark back together, using processor over matter. Meanwhile, Shockwave finally gets Arcee's codes and uses it on protoforms (stolen by Starscream, to make his clones) to duplicate Omega Supreme. Finally, Omega Supreme's clones fly from the Moon to invade the Earth. The episode also shows some of Optimus Prime's memories about being expelled from the Elite Guard and meeting the other main characters.
