Nightmare moon

Nightmare Moon is a tall and volutpuous anthro Alicorn, the same size as Celestia and shared many similarities towards her as well. Her skin color is pitch black, and her hair and tail flow in a starry midnight complexation. Nightmare Moon wears light blue armor with a moon emblem on her chest, and a helmet on her head. Her eyes are more reptilian-like, with her irises slit. Nightmare has a large bust, pillowy thighs and a massive and juicy ass.

She is shown to be very forceful and angered towards her sister, as she is the manifestation of Luna's own doubt and jealousy towards her. In an alternate timeline however, while she had shown a sort of force in her subject, she still has shown some bit of regret for her sister, and willing to listen to her subjects if they do indeed have something important to say. It's possible that Sombra's involvement made her more open-minded than she would normally be.

Nightmare Moon is Luna's alter-ego that she had taken form of 1,000 years prior to the series. It was this change that made Celestia banish her to the moon for the next thousand years, before she made her return, only to be defeated by the Mane Six once again. In an Alternate timeline, Nightmare Moon is the current ruler of the Lunar Empire.

As an alicorn, is it possible that she has a very high level of magic, able to move the moon with ease, much like Luna.
