The Transformers

The Decepticons have managed to construct a device that, once successfully tested, will allow them to travel to Cybertron. Later, they use a reprogrammed Bumblebee to make sure the Autobots walk into an ambush.

Starscream is now in charge of the Decepticons, but all he does is lead them to defeat in battle against the Autobots. But things are about to get much worse when Megatron returns, setting his sights on a new and powerful anti-matter formula.

A battle with the Decepticons leaves Optimus Prime damaged. Several Autobots journey to Cybertron to retrieve a vital part that will help repair him, but the Decepticons take advantage of the situation and launch an attack.

New allies for the Autobots are built, bringing about Grimlock, Slag and Sludge. However, the Dinobots prove hazardous to the Autobots and must be locked away. But they may be the only hope for the Autobots after a battle with the Decepticons.

The Decepticons raid the Ark after tricking the Autobots with a distraction and Sparkplug gets captured. They use a device called a hypno-chip, created by a human named Dr. Arkeville, on Sparkplug to gain control over him. It is all apart of an evil plan to get a work force to create a new space bridge and bring Cybertron to Earth.

Natural disasters plague Earth as The Autobots attempt to stop Megatron's plan. A team of Autobots and Spike head for Cybertron to save Sparkplug, but they could be heading straight for a trap.
