HEAVY METAL WAR

Megatron's six newest reinforcements, the Constructicons ( Scrapper, Mixmaster, Hook, Long Haul, Bonecrusher and Scavenger) loot a construction site and steal its Energy Disks. Megatron, in a temporary hideout, plans to use Scrapper's new invention to give himself all of the Decepticons' abilities, and overcome Optimus Prime in a one on one duel.

While the Constructicons complete the device, Megatron flies to the Autobot Volcano to challenge Optimus Prime to the duel. The loser shall be banished to deep space forever, while the winner can choose where he stays. Optimus Prime accepts the challenge, and Megatron returns to the temporary base.

All of the Decepticons contribute their Powerchip Rectifiers into the machine, so that their abilities and weapons would become available to Megatron for his fight. Starscream points out that Teletran One will detect Megatron's cheating, but Megatron has already planned to have the Constructicons destroy Teletran One during the duel.

The Autobots and Decepticons all gather to watch the duel. Despite Optimus' best efforts, Megatron easily toys with and defeats Optimus Prime. Meanwhile the Constructicons tunnel through the Volcano in efforts to break into the Autobot Base.

Teletran One detects the intruders and activates the Dinobots. The Dinobots catch the Constructicons before they can harm Teletran One, and route them out of the Base with sheer brute force. In retaliation, the Constructicons merge into a giant Decepticon called Devastator and the battle rages as the Autobots escort their wounded leader back to the base.

As they begin repairs, Teletran One diagnoses Optimus' injuries, and Megatron's deception is revealed. The Autobots rush out to fight the Decepticons, and with the help of Hounds holograms, they fool Devastator and force the Decepticons into a lava filled crevasse.

Megatron vows to return as his face sinks below the lava's surface.
