Background
The Witch-king of was a servant of evil, serving the dark lord, Sauron. Over time, his name was forgotten by men and was simply called "Angmar". he was once a noble mortal King who was seduced by the power of a ring of Power given to him by Sauron.

When he was defeated in battle, he was taken to a tomb to be forgotten. Resurrected as a Wraith, the witch-king was made Sauron a lieutenant for his Battle to conquer Middle-earth.

Personality
The Witch-King is an extremely menacing, ruthless, and emotionless wraith whose only reason for existing is to serve his master, the Dark Lord. Being the leader and most powerful of the Nazgul, the Witch King is very commanding and intimidating, commanding absolute respect from his minions and leading them with ruthless efficiency. Originally, back when he was a human king, he was a noble, wise, and fair ruler who sought to protect his people and opposed the forces of evil. He was not flawless however, as he, like the other Nazgul, succumbed to temptation and bore the ring that would turn him into the phantom he became. After succumbing to temptation and being turned into a ring-wreath, he became an utterly soulless entity, figuratively and literally. He was devoid of any emotion whatsoever, possessing utterly no sense of sympathy, mercy, joy, or pleasure. He was permanently cold, cruel, serious, threatening, and merciless. He was so threatening that even Gandalf feared him. He was also shown to be extremely intelligent, having vast knowledge of ancient magic as well as being a brilliant military strategist.

The Witch-King is also a very arrogant and proud entity as well. Due to both his immense power and the prophecy that no man could kill him, the Witch-King was utterly fearless no matter how powerful his foes or how dangerous his tasks were. This contributed to his arrogance, as he never considered the possibility of a woman being the one to vanquish him. He is also either indifferent or condescending to nearly all those around him, viewing most other beings as beneath his power. However, he does show respect for those he feels have earned it, including his master Sauron, the other Nazgul, and his Orc subordinates. Like all the other Nazgul, the Witch-King is completely devoted to Sauron, obeying his master's will without question.
