Prince Lir is a supporting hero in the animated movie, The Last Unicorn. The adopted son of the wicked King Haggard, Lir developed a heroic side over the course of the original movie, unlike his father's malevolent nature. When the Unicorn, under the guise of "Lady Amalthea", and her friends entered Haggard's domain, Lir volunteered to help them, eventually escaping from Haggard's wrath and the Red Bull's ferocity. While absent for most of the conflict, Lir appears in the final events of Heroes vs. Villains War, helping his previous friends once again from the terrible forces of the Horned King and Maleficent.
