Sharptooth

Sharptooth is a tyrannosaurus rex and the main antagonist of the 1988 film The Land Before Time. He kills Littlefoot's mother during the early stages of the film. He has a brutal and determined nature, pursuing the protagonists during their journey to the Great Valley. He becomes (unintentionally) blinded in his right eye by Littlefoot in their initial encounter (though it is sometimes seen open in close ups.)
