My second favorite hero/protagonist would also be Galadriel.

Hero: Bilbo Baggins, especially during and after the Mirkwood section of the Hobbit.

Villain: Sauron. I know, not very original really but I like to think of the Dark Lord as a failed divine utopian and I find that interpretation rather interesting.

My favorite villain is Sauron, though I guess that might be obvious by my username...
