Lord Tirek is the sixth main villain of My Little Pony: Friendship is Magic, and easily one of the most dangerous. Tirek is a centaur from a land far away from Equestria and possesses the ability to steal the magic of other beings. Returning from a long exile in Tartarus, he sets forth to absorb all magic in Equestria, which he failed to do a millennia prior. Early on, he enlists help from Discord, who was initially sent to stop him, playing on the Draconequus' hubris in order to win him over. Knowing loyalty only to himself, Tirek is quick to betray Discord after regaining enough of his strength, eventually stealing even Equestria's Alicorn magic. However, shortly after achieving his goal, he is stopped and imprisoned once more by the newly released Rainbow Power.
