Opaline is a very tall female Alicorn who has long legs, deep purple fur, a large pair of feathered wings of the same color, and dark blue eyes with glittery blue eyeshadow. She also has a long, slightly curved purple horn that is colored paler towards the tip, and glows whenever she uses magic. Her mane is white with light streaks of cyan, and is parted into two side sections with thin braids wrapped around her large, pointed ears. However this is a ruse to hide her true size.
