Who would win in a battle between Sauron and the Night King?

It's difficult to say who would win in a hypothetical battle between Sauron and the Night King. Both characters are powerful in their respective universes, with Sauron being the main antagonist in J.R.R. Tolkien's The Lord of the Rings and the Night King being a major antagonist in the HBO series Game of Thrones.

Sauron is a dark lord who possesses incredible magical power and wields a great mace, while the Night King is an undead creature with the power to raise the dead and control the weather. Sauron is also the master of the One Ring, which grants him immense power over others, while the Night King has the ability to turn humans into wights, his army of undead soldiers.

Ultimately, it's impossible to say who would emerge victorious in a battle between the two, as both characters possess unique and powerful abilities that make them formidable opponents.
