Years before the events of the story, The Dimensional Kingdom is under attacked by an evil being known as Dark Matter, bound on searching for the princess, Nova, and the Great Wishing Emerald, a Chaos Emerald more powerful than the Master Emerald, capable of granting any wish. A young prince, Nebula, defended Nova the kingdom and defeated Dark Matter. In the present day, Dark Matter returned, bound on revenge. He finds a digital version of Scourge the Hedgehog, who struck a deal to steal the Great Wishing Emerald again. Dark Matter also learned of Sonic the Hedgehog, who once fought Scourge, so he takes the form of Sonic in the hopes of him being defeated. A strange shockwave sends Shadow into another dimension, after an attempt to use Chaos Control. He is then confronted by Dark Matter, in the form of Sonic. They end up escaping the dimension, Shadow is defeated, and Dark Matter steals his Chaos Emerald. Sonic and his friends Tails and Knuckles travel to Paradise City for vacation, when they stumble upon an unconscious Shadow, who wakes up and confronts Sonic, mistaking him for Dark Matter. After a brief explaining, Sonic agreeds to help Shadow track down Dark Matter and take back the Chaos Emerald. Sonic meets a mysterious girl (Nova) who tells him about how Dark Matter is after her, and hands him a Chaos Emerald. Nebula heard whereabouts of Dark Matter, aware of his Sonic disguise. He calls Team Chaotix (Vector, Charmy and Espio), to help track him down. They accidentally send him the wrong coordinates, and confronts the real Sonic instead. Tails and Knuckles explain that they're trying to help, and how Shadow has seen Dark Matter. Meanwhile, Nova runs into Dr. Eggman, who is interested in the crystal around her neck, and kidnaps her. Sonic and the group arrive and battle Eggman. Dark Matter joins forces with Eggman, handing him some valueable information. After a brief battle, Eggman, who still held a grudge against Shadow, kidnaps him instead. Dark Matter banishes Sonic, Tails and Knuckles into another dimension, and Nova and Nebula escapes. Vector and his team arrives to check up on Nebula, and he explains what he's been through. Vector agrees to rescue Shadow while Nebula tries to hide Nova from Dark Matter, which did'nt go well after Amy meets them and gets banished by Dark Matter. Sonic, Tails and Knuckles are now trapped in another dimension with no way out, and are mistaken for Dark Matter, and are arrested by the Dimensional Guard. Sonic explains to the emperor that Nova and Nebula are in danger, and that they need a way out. The emperor gains their trust and shows them the Chaos Emerald, only to find that it was stolen. Sonic and friends run into the courtyard and find Dark Matter, who is stealing the Chaos Emerald to open the Dimensional Gate and stealthe Great Wishing Emerald. The fight is cut short when Data-Scourge attacks him, who was tricked. Scourge steals the Emerald and escapes. Dark Matter then takes the form of Knuckles and collapses the balcony underneath Sonic Tails and Knuckles. Later, Amy finds the castle. Vector and his team commence their rescue mission to rescue Shadow. The rescue turns around when Rouge appears to also rescue Shadow and sneak data into Eggman's computer. After a daring escape, Shadow lands in some ruins where he finds another Chaos Emerald. Nova and Nebula use an emergency Chaos Control to warp back to their own dimension, only to run into Scourge. Scourge tricks Nova and Nebula into finding Chaos Emeralds, which while on the way, Scourge develops romantic feelings towards Nova. Nebula steals the Chaos Emeralds behind Scourge's back and gives them to Sonic, Tails and Knuckles, who managed to free themselves from the rubble. Amy happily runs into Sonic and friends later. Scourge, enraged at the stolen Emeralds, reveal that his emotions began causing him to glitch out, causing Nebula to strike him with his staff, revealing his true form, then disintegrating. Sonic and friends use the Chaos Emerald to warp back home, but end up in a different dimension, where they're confronted by Dark Matter again. Dark Matter escapes with all the Chaos Emeralds in their possession, leaving them trapped again. Eggman reads Rouge's data learning that if Nova dies, the Dimensional Crystal drains out and the Universe dies with her. He betrays Dark Matter, and Dark Matter escapes to open the Dimensional Gate. He uses the Great Wishing Emerald to banish everyone into their own personal Dimension, with Nova and Nebula held captive. Everyone escapes their own dimension and meet up at the Dimensional Gate. Sonic and Eggman plead a temporary truce after learning about Nova's fate. Nebula enters the gate to battle Dark Matter, who has transformef into a giant monster. Nova believed that he was outmatched, so she attempts to hand him the Chaos Emeralds. Open, Dark Matter mortally wounds Nova and escapes. Nova dies in Nebula's arms as the Universe begins to fall apart. Sonic helps Nebula out by fighting Dark Matter in their Super forms. After an epic battle across dimensions, Dark Matter is defeated forever, and Nebula takes the Great Wishing Emerald to revive Nova. Sonic and friends use the Emerald to return home and go back to their daily lives.
