Agent Fowler has some explaining to do under the threat of military tribunal and Team Prime's termination.

Starscream discovers cloning technology just as Airachnid readies her Insecticon army to attack the Decepticon ship and destroy Megatron. Bulkhead, who has no idea how he ended up on the ship, gets unwillingly caught in the middle of this mess.

In order to get their ship airborne again, the Decepticons inject Dark Energon into its system, but instead of obeying Megatron, the ship develops a mind and agenda of its own.

Miko sneaks aboard Wheeljack's ship to unleash her vengeance on the Insecticon who has nearly killed and seemingly permanently disabled her partner Bulkhead.

Miko is deeply shaken by Bulkhead's injury, so Arcee decides to cheer up the human girl with story about her past adventures with her former partner Cliffjumper.

A rookie Autobot arrives on Earth, but he seems to be way too eager to fight the Decepticons, much to the annoyance of the other Autobots, especially the crippled Bulkhead, who is unable to go to battle.

While Smokescreen becomes accustomed to Earth, the Decepticons detect an Iacon relic--the Star Saber.

Optimus receives a message from Alpha Trion, who tells him that the Omega Keys will revive Cybertron. Meanwhile, Megatron plans to craft a Star Saber for himself.
