Moon Dancer

Moon Dancer is a female unicorn pony who first appears in the season five episode Amending Fences. She has a light yellowish gray coat, red mane and tail with purple highlights, purple eyes, and a cutie mark of a crescent moon and three stars, the latter possibly referencing three close friends of hers. Her name is spelled "Moon Dancer" in Amending Fences' closed captioning and with a trademark symbol in Playskool merchandise and "Moondancer" in Amending Fences' ending credits, in the comics, in Gameloft's mobile game, in Friendship is Magic, part 1's closed captioning, in Princess Twilight Sparkle and the Forgotten Books of Autumn, and sometimes with a trademark symbol in Enterplay's collectible card game.

Design
Moon Dancer was designed by Kora Kosicka. She shares her mane and tail style with Twilight Sparkle, though in her marehood, she sports a black two-hooved sweater, wears her hair up with a pink 'clacker' hair tie, and a pair of thick black eyeglasses.

Moon Dancer shares her name with a G1 unicorn and a G3 Earth pony, and her design is based on the G1 unicorn. Concurrently with G4, G1 Moondancer has been reintroduced IDW Publishing's Transformers vs. G.I. Joe Issue #13.

Season one
Moon Dancer is first mentioned in Friendship is Magic, part 1 by Twinkleshine and Spike. Twinkleshine says to Twilight Sparkle that "Moon Dancer is having a little get-together at the west castle courtyard," but Twilight declines the invitation to focus on her studies. Spike later accidentally ruins a gift for her after being knocked aside by Twilight.

Season five
Moon Dancer makes her first in-show appearance in Amending Fences. She is shown to be an asocial recluse, living alone in a dilapidated Canterlot house and focusing only on her studies. As a filly, she was friends with Twilight Sparkle. Twilight learns that after not showing up to the party Moon Dancer had thrown in the first episode, Moon Dancer became heartbroken and withdrawn, rejecting friendship altogether.

Twilight approaches Moon Dancer as a potential friend and appears to reach her at first due to the two's mutual love of learning, but Moon Dancer eventually snubs her. After being lured to a party reminiscent of the one she had thrown, Moon Dancer vents her pent-up frustrations at Twilight. Twilight apologizes for the hurt she caused, and Moon Dancer comes to accept friendship once more. She is last seen playing a ball game with Twinkleshine, Lemon Hearts, and Minuette.

In The Cutie Re-Mark - Part 1, Moon Dancer sits next to Spike during Twilight's speech, waking him when he falls asleep while changing slides.

Season six
In Flutter Brutter, Moon Dancer is depicted in a photograph in Pinkie Pie's wallet.

Season seven
