The end is near. Galvatron has used his dark energies to open a wormhole for the D-Void to appear and consume Cybertron. Although Megatron and the Autobots fight back, all hope is almost lost as Vector Sigma inside of Cybertron is consumed, and the 'Dark Universe' begins to appear. In a last second save, Optimus Prime uses the powers inside the Autobot Matrix of Leadership, convinced by Rodimus as being the only way to stop that universe from entering and consuming ours, to close the wormhole and force the 'Dark Universe' back.
