After Eggman released a whole bunch of multiversal threats to this world, those are not the only things that came out. Now, there's not one, not two, but THREE other Sonics in this world that came through! There's the Adventures of StH cartoon, or as we may call him Classic Sonic, then there's Movie Sonic, and then there's the dumbest version: Boom Sonic. But now Sonic and his friends new and old must prevent the threats Eggman unleashed from destroying Mobius. The threats are an alternate version of Nine from Sonic Prime, Eggman Nega from an alternate timeline of this world, and IDW's The Deadly Six!!! Now, it's up to the Sonics and their friends to stop them. But by the end of it, they'll have to face the overpowered, invincible, and powerful Infinite!
