We have Principal Celestia of My Little Pony: Equestria Girls, Rainbow Rocks, and Friendship Games. Apparently the pay is so low that no one wants this job, considering that she never questions these students like Twilight Sparkle, Sunset Shimmer , and the Dazzlings walk through he door. Now she has been captured in a burqa.

Principal Celestia is a character in the movie. She appears as the Principal of Canterlot High. She is the humanized version of Princess Celestia, the eldest of the Alicorn Princesses in Equestria.
In the movie, Twilight goes to her when she learns where her crown is. Principal Celestia tells her that the only way to get the crown is to be voted Princess of the Fall Formal, and lets her sign up. At the Fall Formal, she announces Twilight as the winner. She later commends Twilight for her role in defeating Sunset Shimmer. She appears to be just as wise, fair and kind in the human world as she was in Equestria. In the sequel, Rainbow Rocks, Principal Celestia and her little sister, Vice Principal Luna, are enjoying all the students' preparations for the Canterlot High School Musical Showcase. When Sunset Shimmer and the Rainbooms come to speak to them about the Dazzlings and the dark magic they're using, Celestia and Luna have already been placed under the Dazzlings' spell as well. For the rest of the movie, they are seen judging the competition, but are freed from the Dazzlings' spell, off-screen, following the destruction of the Dazzlings' ruby pendants by the Rainbooms, and then sending the Dazzlings running off in disgrace with the infuriated students. Once released from the trance, it is possible that she either expels the Dazzlings or put them in detention.
