Large creatures of great strength frequently in the service of the Enemy. Trolls were humanoid in shape but monstrous in appearance. They were much taller and broader than Men. They had scaly skin and large flat feet with no toes, and their blood was black.  

Trolls were generally rather stupid. They did not build or create anything. Trolls hoarded riches that they stole, and they often ate the people they robbed. Trolls had no language of their own, though some Stone-trolls in Eriador were able to speak the Common Speech and Sauron taught Trolls in his service the Black Speech.  

Trolls were incredibly strong and powerful and difficult to kill. Their main weakness was that most Trolls turned to stone when exposed to sunlight.
