Lord Tirek

Lord Tirek (/ˈtɪrɛk/ TIRR-ek) is a fictional character who appears in the fourth incarnation of Hasbro's My Little Pony toyline and media franchise, beginning with My Little Pony: Friendship Is Magic (2010–2019). He serves as the main antagonist of the fourth season finale and a major recurring villain throughout the series. He is voiced by Mark Acheson.

Lord Tirek is depicted as a powerful and malevolent anthropomorphic centaur who seeks to absorb all magic in Equestria to gain ultimate power. As he drains magic from ponies, he grows larger and more powerful, transforming from a weak, elderly creature into a massive, intimidating beast. He is characterized by his red skin, human-like upper body, horse-like lower body, and his ability to steal magic through energy beams from his hands; according to the book The Art of Equestria, "because there are no humans in Friendship Is Magic, [Tirek's] head is more bull-like, with a goat's shaggy whiskers."

The character is based on the original Tirek from the 1984 television special Rescue at Midnight Castle.
