Who would win in a fight between Superman or Harry Potter?

Neither would fight they wouldn't want to hurt each other but if they had to probably harry cause he could just use the killing curse on superman but really it would depend on what was stronger magic or krypton

While your answer is valid in some parts, Superman is completely invulnerable except for when Kryptonite is tied to him or touches him. So, in order for Harry to win he would need to use a sticky spell on Kryptonite and Superman, taking away his invulnerability and then use the killing curse.
