Witch King of Angmar

The Witch-King of Angmar is one of the three secondary antagonists (alongside Gollum and Saruman) of J.R.R. Tolkien's epic fantasy novel The Lord of the Rings.

In the novel, he serves as the main antagonist of Book 1 of The Fellowship of the Ring, a minor antagonist of Book 4 of The Two Towers, and the secondary antagonist of Book 5 of The Return of the King.

In the live action films, he serves as one of the two main antagonists (alongside Saruman) of The Fellowship of the Ring and a major antagonist of The Return of the King.

Once a mighty King of Men, he was granted one a Ring of Power by the Dark Lord Sauron. Eventually he became corrupted and transformed into a Ringwraith, becoming Sauron's deadliest servant.

He is the Lord of the Nazgul, Lord of Minas Morgul, founder and former ruler of Angmar, and Sauron's second-in-command. He was a brilliant strategist, a powerful warrior, and a terrifying sorceror. He was so powerful that it was prophesied no living man can harm him.

Among his achievements include the destruction of Arnor, slaying the last King of Gondor (before Aragorn assumed the throne), leading the search for the One Ring, and leading Mordor's army against Gondor.

He was eventually vanquished at the Battle of Pelennor Fields, slain by the Rohirrim princess Eowyn and the Hobbit Merry.
