Unicron's body, damaged once more, lies in the dark reaches near the fissure. The Decepticons raid Alpha-Q's new planets for the Energon necessary to revive Unicron again. Megatron directs Unicron's body to retrieve his head, extinguishing the Energon Sun and killing Alpha-Q in the process. Unicron begins to take over Megatron's body. Unicron's body is destroyed in battle by Optimus Supreme with the help of some of the other Autobots. Unbeknownst to anyone, Unicron lives on in two forms: his minuscule Spark, and his consciousness, which lies buried in Megatron's mind. With subconscious nudgings, Unicron leads Megatron to a large reservoir of "Super Energon" beneath Cybertron's surface, which transforms him into Galvatron. After a series of failed battles, Galvatron exposes himself to the Super Energon once again and grows to a gigantic height. Unicron seizes control of his body as a new vessel and sets out to rejoin with his Spark, but a Primus-empowered Optimus Supreme engages him in battle again, and draws all of Unicron's consciousness out of Galvatron and seals it within his own Spark. Enraged, Galvatron prepares to destroy Unicron's Spark, but it merges with him, enlarging him again. He battles again with Optimus Supreme, this time bolstered by the combined energy of all his troops' Sparks. Meanwhile, Primus merges with the Super Energon, creating a fledgling sun that arrives at the site of the battle. Taking control of his body for a brief moment, Galvatron sacrifices himself to stop Unicron, plunging into the infant sun, which ignites and gives new life to Alpha-Q's worlds.
