It had been months since Twilight Sparkle and Spike the Dragon was aided by Sunny Starscout, Hitch Trailblazer, Sparky Sparkeroni, Izzy Moonbow, Pipp Petals, Zipp Storm and Sonic the Hedgehog to recover the pieces of the Tree of Harmony to restore Equestria. Things get weird as The Mane 6, Spike, the Mane 5, Misty and Sparky get summoned to a place called New Yoke City and meet Team Movie Sonic, Tom and Maddie. They discovered their friend, Sonic, recklessly broke an item called the "Paradox Prism", shattering his world like with Equestria months ago. Now Sonic, Team Movie Sonic, Tom, Maddie, the ponies, Spike and Sparky travel through other worlds called Shatterspaces in a new multiverse called the Shatterverse to reconnect with Sonic's friends and restore the Paradox Prism before the Chaos Council get their greedy hands on them.
A Sonic Prime and My Little Pony crossover. Zipp would be very suspicious about Nine like how I am and how she was with Misty before she was reformed. Also, it's a voice actor joke too, since there are MLP G4 voice actors/actresses in Sonic Prime and James Marsden did Hitch in A New Generation and Tom in the Sonic Movies. Sonic and Twilight miiiiiiight be together in this story as a ship. Don't blame me if you don't ship 'em.
