The awakening of Unicron from within the Earth draws the attention of Lio Convoy in another dimension. Traveling across realities, he arrives to find that the Autobots and Decepticons have already defeated Unicron but elects to remain for a time to safeguard against his potential return. Using his ancient sword and the power of his "Energon Matrix", Lio Convoy carves up the remains of one of Unicron's rock-and-stone avatars to create the "Gaia Armor", severing its link to Unicron but allowing it to retain the power of Dark Energon.
