I will say this, Sauron was a BEAST in the book. If I remember right, he single handy took over a entire fortress and made it his own. As well be able to shape-shift into anything he wanted. He (please correct me if I'm wrong, I haven't red the book in ages) shape-shift into one, of the most BADASS werewolves of all times (eat that Twilight). Though..he still got beat by the "heroes" who fought him, but I believe one of them was like..a monster dog or something. I have to reread it to make sure how he lost that battle....
