- Trolls first appear in Norse mythology and the term is originally another name for Frost Giants but later, became a separate race of creatures in Scandinavian folklore, sometimes depicted as either as ugly and stupid man-eating creatures that turn to stone on being exposed to sunlight, or as being exactly like humans. In both cases they live far from human settlements and often overrun farms and kidnap people.
- Trolls are magical creatures appearing in the Harry Potter series as large human like creatures that have an aggressive and unpredictable behavior.
- Trolls also feature in the Lord of the Rings and The Silmarillion books by J.R.R. Tolkien, where they appear as a large, monstrous and unintelligent humanoid race inhabiting Middle-earth who were created by the first Dark Lord, Morgoth, and served him and later served his greatest surviving servant, Sauron, after Morgoth was defeated.
- The Forest Trolls who appear in The Fire of the Phoenix have a very similar appearance to the Trolls from the Disney animated movie Frozen.
