Una colisión con el Prisma Paradoja envía a Sonic a un mundo paralelo llamado Nueva Yugork, donde el opaco ambiente se ve extrañamente familiar.

Un apagón les da a dos rebeldes la oportunidad de irrumpir en un laboratorio donde el Consejo del Caos está estudiando la extraña conexión de Sonic con su fuente de energía.

Para proteger el fragmento de prisma, los rebeldes luchan contra el Consejo del Caos. Luego, Sonic hace un descubrimiento impactante sobre los eventos que destruyeron su mundo.

En una dimensión llamada Laberinto Boscage, Sonic encuentra versiones de sus amigos que viven en los árboles, quienes le advierten de un monstruo que habita en la jungla.

Para poder volver a la dimensión correcta, Sonic debe luchar contra el monstruo de la jungla que les declaró la guerra a sus amigos y capturar el poderoso fragmento de prisma.

De vuelta en Nueva Yugork, Sonic intenta convencer a Nueve de que se una a la Resistencia, pero Nueve está enfocado en construir un nuevo hogar.

En el tropical Ningún Lugar, Sonic conoce a una amistosa banda de piratas y su misterioso capitán, a quien le encantan las fiestas.

Mientras el equipo de Sonic se apresura para obtener el fragmento, se dan cuenta de que no son los únicos que lo están buscando. Solo hay una forma de ganar: ¡deben ir rápido!

Shadow ambushes Sonic in the void of the Shatterverse to confront his rival about the destruction of Green Hill — and take matters into his own hands.

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.

To save Captain Dread's crew and recapture the Shard, Sonic will have to do what he does best: act fast. Luckily he has help from an unexpected ally.

Friends become foes when Captain Dread's crew questions Sonic's loyalties. Then, a battle on the high seas breaks out over possession of the Shard.

The Chaos Council returns to New Yoke City more powerful than ever, forcing the rebels to come out of the shadows and bring a fight to their front door.

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.

The key to reassembling the Paradox Prism lies in one of the Shatterspaces. But can Nine and Sonic find a portal to safely transport the Shards there?

While Nine reassembles the Paradox Prism, Shadow and Sonic battle the Council to buy more time — but there's one big surprise they weren't counting on.

With the Paradox Prism in his hands, Nine begins building the Grim into his own personal paradise — unless Sonic and Shadow can convince him otherwise.

To get help in the fight against Nine and his winged lackeys, Sonic heads to New Yoke and forms an allegiance with the very last people he ever expected.

Sonic races to No Place to save the pirates before their world collapses, but Nine still needs Sonic's energy to power the Paradox Prism.

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.

To beat the biggest bot on the battlefield and get one step closer to Nine, Sonic needs to move fast — and accept a little help from his friends.

Sonic discovers a new ability that may be the key to defeating Nine. But Nine's endless army has only one purpose: to capture Sonic's energy.

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?
