Which actor voices the character Discord in My Little Pony: Friendship Is Magic?

The actor who voices Discord in My Little Pony: Friendship Is Magic is John de Lancie.

De Lancie gives voice to Discord, the reality-bending draconequus and spirit of chaos and disharmony. Discord first appears in the two-part season-two premiere “The Return of Harmony,” where he escapes his stone prison and disrupts Equestria by turning the friends against one another.

The casting has a notable Star Trek connection. Lauren Faust and the production team based aspects of Discord on Q, the omnipotent trickster character that de Lancie played in Star Trek: The Next Generation. Rather than hiring an imitation, the show ultimately cast de Lancie himself, giving Discord a recognizable mixture of charm, theatricality, mischief, and menace.

Discord later becomes an unlikely ally after Fluttershy helps reform him in “Keep Calm and Flutter On.” That change does not erase his chaotic personality; instead, it redirects his powers toward friendship and occasional heroism. John de Lancie is therefore the canonical English voice actor for Discord in Friendship Is Magic, not Tim Curry, Maurice LaMarche, or Mark Hamill.
