*IMPORTANT* This is a fan-made boss fight and is not in the actual Undertale game.
Alphys NEO is the boss that only appears on the Genocide Route. She is considered to be the most difficult enemy.She is harder than Mettaton NEO whose does absolutely nothing but instantly takes between 900,000 and 999,999 damage.
