Mama Sharptooth

Mama 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, Mama Sharptooth is the mate of Papa Sharptooth and the father of Chomper. Initially developing a hostile attitude towards Littlefoot and his friends for accompanying Chomper, due to her overprotective behavior, Mama Sharptooth eventually learned the errors of his ways and tried to make amends with Littlefoot and the others. Alongside with her mate, she appears in the second Heroes vs. Villains as one of the new foes the heroes encounter, though whether she would defect to the side of the heroes or become hostile enemy is currently left to be answered.
