With the series coming to a close and Energon due to take over as the active franchise comic, issues 14–18 were dedicated to the coming of Unicron, with cameo appearances by several G1 characters. With Don Figueroa on art, it detailed the coming of the Heralds of Unicron into the Armada dimension to secure the Mini-Con Matrix and kill all of Unicron's enemies. The arc introduced Jetfire and the concept of Powerlinking, as well as having a battle between Armada Megatron and G1 Galvatron, Unicron's chief Herald. The final issue, again drawn by Guidi, served as a bridge between the Armada and Energon series, detailing Unicron's defeat and Megatron's disappearance.
