Season 1

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.

The Autobots on Cybertron evade capture and work toward finding a way to counteract the effects of the hypno-chips. Meanwhile, Optimus Prime leads the remaining Autobots in a battle to put an end to Megatron's plan.

A meteor is about to crash in the earth and maybe be a good to get a lot of energy, so Optimus Prime order the Dinobots to guard the meteorite to avoid the Decepticons take this energy, but Megatron has a plan to use the Dinobots against Optimus Prime...

Starscream is going to destroy the Earth and take the energy from the explosion to rule the Universe. The Autobots and Decepticons must team up to stop that disaster.

The Earth is returning to the ice age, becuse an evil plan of the Decepticons who have found a new partner...

The Constructicons, recently created for the Decepticons, have built a device to give Megatron the powers and skills of his soldiers. All this is to give him the advantage in a challenge he issues to Optimus Prime. And if Optimus loses, he and the Autobots must leave Earth.

The Autobots discovers that the Decepticons are trying to make a new weapon with the energy from the center of the Earth, controlled by a gem in a pyramid in Peru. The Autobots needs some backup from their old friend Skyfire.

The Decepticons discovers an old type of Decepticons, the Insecticons. They will ally to destroy the Autobots, who will have to face them in another great battle.
