Based on the movie: Sonic the Hedgehog 2, but with some changes.

Eight months after settling in Canterlot City, Sonic is eager to prove that he has what it takes to be a true hero. His ultimate test comes however when the evil Dr. Robotnik returns, along with his new partner, Knuckles, searching for a mysterious mystical emerald that has the power to wipe out civilizations.

Meanwhile, graduation is growing near for CHS, but the upcoming ceremony and pre-graduation party were ruined due to an “incident” by the CMCs. Luckily, the whole school, including the Equestria Girls, were invited to a trip to Hoofolulu, Hoovaii to have their graduation there by none other than Twilight’s favorite astrophysicist, Rosette Nebula. 

But there is just one problem. The Dazzlings were hired as music entertainment for the event instead.

While the Equestria Girls investigate the Dazzlings' sinister plans, Sonic teams up with the CMCs, Spike, Tempest Shadow, and their new allies, Miles "Tails" Prower and a mysterious new man who called himself, “Prism”. And together, they all race across the globe to locate the emerald before it falls into the wrong hands.
