Starlight Glimmer

Starlight Glimmer is an Equestrian unicorn and the main antagonist of the Season 5 premiere of My Little Pony: Friendship is Magic. Her back story and plans of taking away ponies' cutie marks and creating a utopia-like community where all ponies have equal-sign cutie marks to represent 'being equal' have yet to be revealed. All that's known is that she is the ruler of the utopia, steals the cutie marks of the Mane 6, and has a vastly different and rather sinister view on friendship and the individual talents that make Equestria's ponies so special.
