Plot
Following the death of Megatron the Autobots have been living peacefully on Earth without the threat of the Decepticons. However, one day Daniel's inventor father, Spike Witwicky, goes missing. The Autobots agree to help Daniel find his father and soon Optimus begins to suspect Decepticon involvement. At their new lair in an abandoned mienshaft, the Decepticons are holding Spike as their hostage, planning to use his knowledge of Cybertronian technology to build them a space bridge, which will allow their allies still on Cybertron to invade Earth. Megatron rises from the lake and kills Starscream, having his body dumped in a river below. However, Starscream comes back on line and notices that he possesses a fragment of the Allspark, which is keeping him alive. He decides to use this to his advantage.

The Autobots eventually figure out Megatron's plan and attack the mine shaft as he begins to activate the space bridge. Starscream then appears and attacks Megatron, but Megatron deflects the attack and Starscream is sucked into the collpasing space bridge. Megatron fights Optimus, who then locks Megatron into a pair of status cuffs. The Decepticon leader is also sucked into the space bridge as it explodes. Afterwards the team celebrates another victory.
