Mettaton:

Genocide: Basically the known Unitale battles, but with normal damage so it takes ~80 perfect hits with the empty gun to kill Mettaton. 90 ATK, so 18 damage per hit, and 90 DEF. Also, the explosion puts you at 1 HP no matter what, and there are no save points later on. Not as hard as the previous Undyne the Undying fight, but still harder than normal mode Sans.

Pacifist/Neutral: Now does 9 damage per hit, and has 47 DEF. Alphys Neo fight will happen after the quiz if you killed Undyne. Also, she will not help you with the quiz if you killed Undyne. You die if you get one quiz answer wrong.
