Starlight Glimmer

Starlight Glimmer is a female unicorn pony and recurring character, initially an antagonist but later a protagonist, in the series. She first possibly appears in My Little Pony: Friends Forever Issue #14 and first explicitly appears in the season five premiere. From The Cutie Re-Mark - Part 2 to Celestial Advice, she is Twilight Sparkle's student in the ways of friendship. As of A Horse Shoe-In, she is the principal of the School of Friendship. She is called Starlight Shimmer in some other media.

In When the Cold Breeze Blows Away, even though she has been framed for failed using a dirty bomb to bombing Qadon (an industrial city in Gerasecia) by a Black Changeling disguised as her after counter-terrorists of the Federal Police of Gerasecia disabled this dirty bomb, she would find way about the one who framed her when Gerasecia attacked Equestria anyway
