Nazgul is a Lord of the Rings minifigure That was released in 2012. They were once men, nine kings. When Sauron gave them the nine rings, they slowly turned into what they are now, Nazgul, Ringwraiths. The lead Nazgul is the The Witch-King of Angmar, who was slain by Eowyn and Merry. the only named Nazgul was Khamul the Easterling, who was second in command and second-most powerful to the Witch-king. He pressumably became the lead nazgul after the Witch-king's death.
