sunset shimmer
Major My Little Pony character and reformed antagonist introduced in the My Little Pony: Equestria Girls series. Originally a unicorn training under Princess Celestia prior to Twilight Sparkle, who abandoned her studies to cross through the mirror portal to the human world.
Unlike the others, she has no canon human world counterpart that we know of, though the idea was considered. The human form we see in Equestria Girls is simply a transformation of the pony world Sunset.
