Discord is a major villain in the My Little Pony: Friendship is Magic series. He appears in the first two episodes of the second season: The Return of Harmony parts 1 and 2. He is a draconequus, a chimerical creature with the head of a pony and other body parts which are a mixture of other animals. He is significantly larger than the other characters, including Princess Celestia, although his size seems to be somewhat variable.
Princess Celestia explains that, when she and Princess Luna first came to Equestria, Discord ruled and the land was in a state of permanent chaos and misery. The divine sisters rose against him and trapped him in stone with the Elements of Harmony. Discord was later accidentally released from his petrified state due to the actions of the Cutie Mark Crusaders.
Discord is described by Celestia as the "Spirit of Disharmony," and is seen to delight in spreading chaos and pandemonium for its own sake. He demonstrated nearly unlimited powers, including physically transforming himself and all of Ponyville, and reversing the personalities of the Mane Six, which also turned them gray. Fans refer to this as being "disharmonized."
Discord has a very mischievous personality, preferring to tease and banter with his enemies rather than attacking them outright. He is also seen to prefer to manipulate them and undermine their confidence, and is extremely arrogant.
