Galvatron is killed by Megatron using the Star Saber, and the other Heralds are destroyed in their captured Decepticon base by an explosion engineered by Jetfire. Unaware of his Heralds' failure, Unicron now threatens to destroy Prime, but the Mini-Cons and Jetfire manage to rescue Prime, with the power of the Mini-Con Matrix upgrading them and combining them into their Powerlink mode. They hold off Unicron long enough to escape back to their universe. Unicron comes to the "Armada" universe himself, where he is attacked by a combined force of Autobots and Decepticons. They distract him long enough for the Mini-Cons to access the power of the Mini-Con Matrix and destroy the Chaos-Bringer.
