Onyx is a female Unicorn pony in the fifth generation of My Little Pony who appears in My Little Pony: A New Generation, My Little Pony: Tell Your Tale and My Little Pony: Make Your Mark. Before magic returned, just like many unicorns, Onyx always held a somber mood and poor posture. However, she always has a creative and poetic side. While she gained some enthusiasm with the return of magic, it was not significant. Onyx often appears with Dapple and perform together. In the Tell Your Tale series, she is a blue unicorn with dark purple mane that covers her right eye in a bang. She has magenta eyes, purple hooves, and a dark red scarf and beret. Her cutie mark is a hot pink feather pen.
