Who is the Greatest hero of all ages?

[Saraphim]

One word: Fingolfin.

If I had money, I would fund a Silmarillion movie just to see Melkor and Fingolfin fight to the death. It's my favorite scene in the whole book.

Here are some more heroes that I'd give a round of applause to:

Thorondor, Luthien, Beren, Huan, Idril, Tuor, Turin, Hurin, Huor, Morwen (one heck of a family there), Finrod Felagund, Glorfindel, The entire Fellowship, Eowyn, Elendil, Isildur, Beleg and a ton more.
