Antagonist = Adversary/Opponent
Who's the mean/bad guy I dislike most? That's a hard thing to choose.
But I think antagonist is kinda up to interpretation so here's mine.
Denathor, father of Famamir and Boromir, Steward of Gondor.
He uses a Palentir to see what Sauron wishes him to see.
This is why you wear gloves at all times when handling a Palentir.
Who's you favorite antagonist?
