Mountain trolls could be found in the mountains of Middle-earth. Their type helped move the great battering ram Grond into place during the Battle of the Pelennor Fields, which they wielded and shattered the large gates of Minas Tirith with. Members of the species also were seen opening the gates of the Black Gate.
Mountain-trolls were very large, larger than Hill-trolls, and had brownish skin.(Non-canon)
The Mountain-trolls make dangerous opponents in battle. These trolls are smarter than Cave-trolls, and their power to lift massive objects to use as weapons makes them deadly. They are assumed to be strong enough for other heavy tasks as well. They are stronger than cave trolls due to their harsh environment.(Non-canon)
