Undertale full game neutral and true pacifist. If you do not take out a single monster, you cannot take out anyone. At all. You will get neutral (when you fight asgore and Omega Flowey) if you don't kill anyone, Flowey gives you a chance to get true pacifist.
The game starts when a human Frisk falls into the underground. Toriel saves you when Flowey is about to finish you off. Toriel also shows you how to play the game. The goal of the game is to beat it without fighting. Basically being a pacifist.
