Papa Sharptooth

Papa Sharptooth is a former antagonist, turned anti-hero, in the second installment of The Land Before Time series The Great Valley Adventure, and a supporting protagonist in the fourth installment The Mysterious Island. A Tyrannosaurus Rex, Papa Sharptooth is the mate of Mama Sharptooth and the father of Chomper. Initially developing a hostile attitude towards Littlefoot and his friends for accompanying Chomper, due to his overprotective behavior, Papa Sharptooth eventually learned the errors of his ways and tried to make amends with Littlefoot and the others. Alongside with his mate, he appears in the second Heroes vs. Villains as one of the new foes the heroes encounter, though whether they would defect to the side of the heroes or become hostile enemies is currently left to be answered.
