She then follows the crown shortly after. Princess Celestia reveals that Sunset was a former student of hers who began her studies not long before Twilight did. However, when she didn't get what she desired as quickly as she wanted, she turned cruel and dishonest, eventually abandoning her studies to pursue her own path. In this other world, Sunset has been living as a human and student at Canterlot High School for some time. She discovers that Fluttershy found the crown and turned it over to Principal Celestia, much to Sunset's annoyance. Sunset Shimmer appears in My Little Pony Equestria Girls: Friendship Games, competing on the Wondercolts' team in the Friendship Games' motocross event. She is tasked with keeping magic out of the event, but she gets worried that she might fail at understanding how magic works in the human world and that she doesn't have Princess Twilight to help her with her task.

Sunset uses the device to harness the magic of friendship from her friends to stop Twilight's rampage. In the end, Sunset realizes that she is fully capable of solving her own problems and that she can't always count on someone else to do it for her.
