Sauron

Sauron is the main antagonist of Peter Jackson's Middle-earth live action film saga, appearing as the overarching antagonist of The Hobbit trilogy and the main antagonist of The Lord of the Rings trilogy.

He was once the servant of Morgoth and was the dark lord of Mordor who forged the One Ring To Rule Them All in ages past in order to conquer all of Middle-earth. After losing the Ring and his physical form and being vanquished for an Age, he eventually regains much of his former power in the Third Age and once again wages war on the Free Peoples of Middle-earth, seeking to be reunited with the One Ring and thus rule Middle-earth. He is the archenemy of the Fellowship of the Ring, especially Aragorn.

He is portrayed by Sala Baker and voiced by Jemaine Clement.
