On Cybertron, Wheeljack develops a device that should disrupt the hypno-chips' control over the humans. Spike attempts another rescue of his father, but is discovered by Shockwave. However, Wheeljack's device works as planned, and the Autobots flee back to Earth with Sparkplug, who is now freed from Decepticon control. Back on the island, Spike remarks to Optimus that Megatron appears to be gone for good, but the Autobot leader, knowing his mortal enemy's survival rate, is not so sure. In space, Megatron comes back online and flies away from the wreckage of the shuttle, vowing revenge.
