When Bokkun shows everyone Eggman's message (telling that the Metarex are starting to gather at galactic coordinates (0-0-0) because of a thousand-year prophecy), the gang starts lifting off to go beat the Metarex once and for all. They leave Shadow behind. However, the Chaotix find Shadow and offer him a ride to galactic coordinates (0-0-0) on their spaceship.

Once Sonic and the gang reach (0-0-0), they find the Metarex fleet there, ready while a Planet Egg warps in from another universe. The Egg is in the center of a planet of water, which, combined with the light of the Chaos Emeralds, help Dark Oak, Black Narcissus and Pale Bayleaf to mutate into a giant plant-dragon named Final Mova. Final Nova then charges into the Blue Typhoon and destroys it from the inside in an attempt to get the Master Emerald. However, Sonic's fleet intervene and start attacking the planet, but then Sonic is catapulted into the air by a pillar of water. Dark Oak then swallows Sonic, who plunges face-first into the planet, and Dark Oak proclaims "Ha! Now Sonic the Hedgehog, how can you hope to defeat us? Water is your weakness, and our strength! Now forestation will be unstoppable!"

Meanwhile, Chris infiltrates Dark Oak's ship to blow Eggman, Bocoe, and Decoe out. At the same time, Shadow and the Chaotix fight more Metarex. Eventually, the ship comes apart to reveal a giant tree, which attaches to the aquatic planet and starts growing to an unimaginable size.
