Blazing Night

Once a regular unicorn pony named Glittering Stars,  She since became Blazing Night after an unfortunate encounter with a demonic crystal. She was wandering in the magic forest, and stumbled on a glowing pink crystal. She attempted to dislodge it in hopes of it being valuable, but in truth it had been buried in the earth to contain the demon within, and when the crystal was moved the demon was freed and fused itself with the essence of Glittering Stars, turning her into something completely new. Her horn became jagged and an extra one grew, bat wings grew out of her body, and her once starlight body became covered with glowing bright pink stripes, and her face became an evil pale. She lost her cutie mark, but her command of magic is completely unchanged, and some new talents have awoken, more demonic in nature. Her personality has changed as well, but she doesn't feel bothered by it. Sometimes she thinks about the mare she used to be, but whoever she is now doesn't mourn them.
