Transformers - The Animated Series

While working on a space bridge, the Autobots and their leader, Optimus Prime, find the AllSpark. After an epic battle between their ship and Megatron, they crash land on Earth in the city of Detroit. After 50 years, the Autobots awake and discover a futuristic world.

Optimus Prime and the Autobots continue to fight off Megatron and the evil Decepticons. Eventually, the team assumes heroic roles in Detroit City.

The Autobots must save Detroit from Starscream, when he kidnaps Bumblebee, Fanzone and Isaac Sumdac for ransom to get the AllSpark.

Optimus Prime and the Autobots set up base at an old auto-parts shop. Meanwhile, Megatron's head comes back online and takes control of several robots to attack the Autobots and reclaim the AllSpark.

An engineering genius tampers with Bumblebee's system and causes him to become Meltdown. This wouldn't be half bad except for the fact that Meltdown's touch burns holes in the Autobots.

Professor Sumdac's latest creations begin to think for themselves. Eventually, these Dinobots start to hunt down the Autobots.

Ratchet thinks back on the time that he spent in the Autobot-Decepticon War. Meanwhile, he must face his past when an old Decepticon foe appears, the bounty hunter Lockdown.

Bumblebee faces off against the newest villain, Nanosec.

Bumblebee and Bulkhead are having fun celebrating their first-ever Halloween with Sari. That is, until the Decepticon Blackarachnia shows up to ruin their good times.

Bulkhead realizes that Sari's newest toy is really evil. Unfortunately, none of the Autobots believe him.

The Autobots go face to face with two new Decepticons, Lugnut and Blitzwing.

Sari is kidnapped, and the evidence points to the Dinobots. So Prowl and Bulkhead head to a mysterious island to investigate with a highly suspicious Captain Fanzone on their tail.

One of Sumdac's ex-workers takes control of an Autobot. He then takes the Autobot out on the town.

Prowl, Bumblebee and Sari head into the forest to find the source of mysterious Cybertronian energy readings.

When Starscream, Lugnut and Blitzwing begin their invasion of Earth, Optimus Prime demands Sari hand over her key for safekeeping. This causes her to run away, only to end up in the clutches of Blackarachnia. Optimus begins to doubt his leadership even when the next stage of Megatron's plot to be rebuilt begins.

Now that Megatron's body is rebuilt, he leads the Decepticons in his search for the AllSpark. When the Autobots fail to defend the Earth from the Decepticons, they must fight harder than ever to protect the AllSpark.
