Sir Rothbart (also known as Lord Rothbart, the Great Animal, or just Rothbart for short) is the central antagonist of The Swan Princess series, serving as the main antagonist of the first and fourth films. He is a cruel and wicked warlock who kidnaps and curses Princess Odette to become a swan, so he can marry her in order to rule the kingdom.
He was voiced by the late Jack Palance in the first Swan Princess film.
