Unicron transforms to robot mode and turns on Cybertron as the combined Autobot/Decepticon armada attempt in vain to stop him. Optimus Prime and Megatron (now Galvatron) enter his body with the human children, and Unicron addresses them through Sideways's form. He absorbs all but Optimus into his collective consciousness and brings the Mini-Cons back under his control. However, from within Unicron's mind, Rad is able to use his connection to High Wire to restore the Mini-Cons' individual minds, freeing the weapons and deactivating Unicron. With the danger apparently over, Galvatron challenges Prime to a final battle, but the hatred between the foes stirs Unicron to life again, and upon realizing this, Galvatron decides to sacrifice himself to ensure there will be no more hatred. Plunging into Unicron's maw and allowing Optimus to escape alive, Galvatron ends the hatred. In a mighty flash, Unicron vanishes without a trace, although at the end of the series he is shown orbiting an unknown planet.
