I freaking love imagining ponies in their Nightmare versions. This is the adorable white and blue DJ Pon-3 (I prefer to call her Vinyl Scratch) corrupted by her desire of a world living inside the eternal WUB!
DJ Nightmar-3 has a black body (as Nightmare Moon and Nightmare Rarity) and a pair of red eyes. Her mane (as the accessories she wears in hooves, legs and neck) glows, reminding how Neon shines. Her mane flows in the air and, when she talks, it start moving as a sound wave. Other Nightmare versions
Hope you like it!
