Cave Troll is a massive fictional creature from The Lord of the Rings, a brutal troll-like beast used by Sauron’s forces in battle. In the story, cave trolls appear as heavily armored shock troops, most famously during the confrontation in Moria, where one attacks the Fellowship. The character serves as a dangerous monster rather than a named individual, representing the overwhelming physical threat of the enemy. Cave Troll is not a human-style character with a personal name, so its full name is best treated as the species-like title.
