Plot

Differences

 * Twilight's friends join her, Spike and Team Sonic into the mirror world.
 * Sunset Shimmer is already reformed prior to the events of this film, as a result, her villain role is given to Neo Metal Sonic, though Eggman is also a villain here, but it's more or less to stop Neo Metal on his own terms.
 * Sunset joins the others back to Equestria in order to make amends with Princess Celestia.

Trivia

 * Sonic and the others are shown to have some knowledge of the human world already due to the events of Sonic X, Sonic Adventure, Sonic Adventure 2, Shadow the Hedgehog, Sonic 06 (even though the events of that game were retconned from existance), and Sonic Unleashed.
