Unicron proceeds to a Predacon boneyard, defeating Predacons Skylynx and Darksteel in battle and bringing hundreds of deceased Predacons back to life as Terrorcons. He leads his new army to Cybertron's Well of All Sparks and engages the Autobots, Decepticons, and Predacons in battle. He confronts Optimus Prime when he senses the Allspark. He fights him on even terms until he strikes Optimus down when Optimus makes a grab for the AllSpark's container as Bumblebee holds Unicron down. Escaping Bumblebee, Unicron flies after Optimus, defeating him before opening the container. He realizes too late that it is a trick, and his Anti-Spark is sucked into the container, freeing Megatron from his control and defeating Unicron. His legions of undead Predacons are destroyed. It turns out that Optimus had stored the AllSpark in the Matrix of Leadership and would soon take the Matrix into the Well, sacrificing himself to ensure the return of Cybertronian life. Now understanding oppression, Megatron relinquishes his hatred and his lust for conquest, leaving for parts unknown to start anew.
