The setting of the Night King in the American TV series "Game of Thrones" is different from that in the original book. This is also an area where people have always been easily confused.

In the original work, the Night King is the thirteenth Lord Commander of the Night Watch and comes from the Stark family. He fell in love with a woman whose "skin was as pale as the moon, her eyes were like blue stars, and her skin was as cold as ice." It's the White Walkers.

He took her back to the Nightfort and called her his queen. He also sacrificed to the White Walkers. Later, he was defeated by Brandon, the "Liberator", the King of Winterland, and Qiaoman, the King Beyond the Wall.

Note that the Night King here did not lead the White Walkers and the zombie army to attack humans. He is a human and lives in the Nightfort with his self-proclaimed queen.

The Night King in the American TV series "Game of Thrones" is defined as the leader of the White Walkers and the Undead. As for his origin, people speculate that he is Bran, but apparently it was not until the end of the show that he was known as Bran. Not confirmed.

In the play, after Bran became the Three-Eyed Raven, he saw the birth of the first White Walker through the Green Vision. The audience is led to believe that the first White Walker is the later Night King, who can transform babies into White Walkers, and can make the dead have the ability to move by raising their hands.
