10. Gollum. All that talk about him crawling through windows and stealing babies just makes me shudder.

9. The Watcher.

8. Balrogs, specifically the Balrog that overthrew the kingdom of Khazad-Dum. I can just picture him reeking havoc across the great halls and mines.

7. The Old Forest. Those are some angry trees!

6. The dungeons of Barad-Dur. It is scary to think about all the possible devices that Sauron might have used on his prisoners.

5. The far north. It's where the greatest evil always comes out of and there just might be some remnants of that ancient evil left.

4. Carcharoth

3. The Barrow Wights. The thing that scares me the most is to think that they were once great men now fallen and cursed by the Witch King.

2. Morgoth, the power-fullest of all the Valar. The depiction of him fighting Fingolfin is just amazing.

1. Nazgul, by far the scariest things that Sauron ever created. The concept of the living dead has been around for years but Tolkien really nails it with these nine.
