really?
in genocide, Undyne the Undying has 23,000 hp, 12 ATK, and 5 DEF.
I have 30,000 hp, 7 ATK, and 0 DEF.
considering the fact that you have 10 LOVE when fighting undyne the undying, and the fact that I am a waterfall encounter, I should be just a bit harder than undyne in genocide.
in pacifist, its not that big of a deal at all because sparing me is easy.
and because there are only two routes in Undertale, I am not even close to undefeatable.
