During a battle with Dr. Eggman, Sonic recklessly destroys an artifact called the Paradox Prism, which shatters the universe and sends him and his friends tumbling through parallel dimensions called “Shatterspaces”. Seeking to restore the universe and save his friends (whom up until the moment he had taken for granted), Sonic races through the “Shatterverse”, encountering alternate versions of his friends and Shadow the Hedgehog while fighting the Chaos Council, a group of dictators made up of five alternate versions of Eggman.
