A power outage gives two rebels a chance to break into a lab where the Chaos Council is studying Sonic's strange connection to their energy source.

To secure the Prism Shard, the rebels battle the Chaos Council. Then Sonic makes a startling discovery about the events that shattered his world.

Back in New Yoke, Sonic desperately tries to convince Nine to join the Resistance, but Nine is focused on building a brand-new home.

As the Chaos Council searches for the Boscage Prism Shard, Sonic realizes there's only one way to stop the robots from destroying the forest: a battle.

Sonic meets his match in Chaos Sonic, a robot version of himself designed to never fail. Meanwhile, the Chaos Council decides to expand their empire.

Sonic must learn to give up some control if he's going to defeat Nine on the battlefield. The first step? Letting the team take over.

Reality will cease to exist unless a selfless hero makes the ultimate sacrifice. But will it be enough to reverse the damage Nine caused to the universe?
