Princess Luna, known as Nightmare Moon when transformed or under certain other circumstances, is an Alicorn pony, the younger sister of Princess Celestia, and the main antagonist of the season one premiere of "My Little Pony Friendship is Magic" as Nightmare Moon. She is also the adoptive aunt of Princess Cadance.
As Nightmare Moon, much like the archetypal, over-the-top villains, Nightmare Moon is overly confident of herself and dramatically declares that the protagonist is a fool (foal) for thinking she can defeat her, and that "the night will last forever." Nightmare Moon uses her magic to set obstacles in Twilight and her friends' path to the Elements of Harmony indirectly, making creatures unwittingly assist her. These include the manticore, whose paw she embeds with a thorn so he'd attack the ponies, or Steven Magnet, whose mustache she cuts off so he'd make the river impassible.
Once transformed back to her former self, Princess Luna is remorseful and tearful upon seeing her older sister. She runs to Celestia's side, apologizing for what she had done. Despite wanting to win over the citizens of Ponyville, the townspeople are frightened of her booming voice and assertive manner. Twilight Sparkle tells Spike that Luna must be having trouble adjusting after being gone for a thousand years.
