This was vent art, but I was feeling better by the time I finished it.

Since any pony can go nightmare (as seen in the official pony comics with Nightmare Rarity) I decided to make a version of Genesis.

Her fur turns black, and her horn grows just like Luna and Rarity, her hair changes to an ethereal cloud like Luna's, only you can see a nebula inside (in reference to her cutie mark). Her cutie mark also changes to an image of a supernova instead of a regular nebula or accretion disk like her normal cutie mark. Those wings are made of magic, and with her massively increased power, they are capable of flight. This does not make her an alicorn.

That new cutie mark, by the way, is the same image as an old antagonist OC I made for her named Perses, who is a corrupted mirror of Genesis. The opposite of her in every way. I don't really do anything with him anymore.
