Princess Celestia, from the tv show My Little Pony: Friendship is Magic, is the daytime ruler of Equestria. She styles herself 'princess', but is almost certainly a goddess. as her duties include making the sun rise. She is larger than the other ponies and (at least sometimes) addresses them as "My Little Pony". She and her sister and co-ruler, Princess Luna (mlp), are the only two alicorn seen on the show.

Word of God states that Princess Celestia is in fact, an Alicorn, and should not be tagged as a pegacorn.
