Naegissa

(The image and character belong to the YouTuber Jyc Row) Naegissa, the High Priestess of Nightmares. Also the only known bat pony in the Infinite Eclipse timeline. Known as the only Crystallized pony to retain their consciousness, she directly serves under Nerath, being the Master Pawn of Nerath to hear her words and control the Crystallized army. She battles with the power of Crystalkinesis and extreme mental assault like her master, as well as having an extremely powerful sense of smell and hearing, able to track any living being anywhere in a five kilometer radius of her. Using crystals of shades of blue and purple in battle, She is depicted to be 10 times stronger than Nightmare Moon. Her body as a whole is as cold as the vacuum of space, her breath and blood cold enough to freeze anything, even Ayzat's magma. Although enemies with Ayzat, she deeply respects her fellow Priestess for her magical power and determination.
