Discord

Discord is a male draconequus and former antagonist of "My Little Pony: Friendship is Magic", introduced in season two. Princess Celestia explains that Discord is the spirit of chaos and disharmony who once ruled over Equestria in a state of unrest and unhappiness, until she and Princess Luna used the Elements of Harmony to imprison him in stone. However, after the sisters lost their connection to the Elements, the spell was broken and Discord broke free. Later in the series, Princess Celestia decides that Discord should be reformed so his magic can be used for good.
