Ep. 46: Starscream lolos dari Atlantis sementara Autobots menghadapi Galvatron dan Menasor di Lemuria.

Starscream manages to break out of Atlantis. Teams 1 and 4 had reached the center of Gigantion, an organic place, and head to Lemuria, the starship where the Cyber Planet Key was. They are then ambushed by Galvatron and Menasor. Metroplex goes to fight with the rebel while Optimus fights Galvatron. Not wanting to risk linking up with Wing Saber, Optimus decides to fight Galvatron without any help. Menasor defeats Metroplex and was about to finish the job when Drillbit and Heavyload stepped in the way. Metroplex convinces Menasor that the Decepticons are evil. Meanwhile, Landmine, Coby and Quickmix went searching for the Key while Override and Evac face Galvatron. Optimus was still in denial when Vector Prime literally punched sense into him. He trusts his team as well they trust him. The backup team finds the Cyber Planet Key and are suddenly attacked by Starscream who pushes Quickmix at a wall. Landmine invokes the power of the Cyber Planet Key to enlarge himself to combat Starscream. In the end, he uses his Cyber Tempest to throw Starscream through the ceiling. Optimus uses Metroplex's axe to defeat Galvatron. Once Landmine gives him the Key, he shrinks back to normal size. The Autobots had the Key and were ready to head back to the surface.
