What if I do genocide before pacifist?

▶

If you do genocide before pacifist, you will notice a significant change in the game’s storyline and endings, as completing a Genocide run will permanently alter your save file, making it impossible to achieve the True Pacifist ending without manually erasing your file. This means that even if you try to spare every monster and complete the Pacifist route after a Genocide run, the game will still end with a sinister cutscene implying that you will ultimately kill everyone anyway.

Understanding the Consequences of Genocide Before Pacifist

FAQs About Undertale’s Genocide and Pacifist Routes

General Questions

1. What happens if you do a true pacifist run after a genocide run? After finishing a Genocide run, you’ll notice the change in the Pacifist run when you do it again, but only at the very end of the run, and even a True Reset can’t erase that.
2. Is true pacifist or genocide harder? Pacifist (spare-em-all) runs are generally the easiest, neutral (kill at least one boss, but not all) runs seem in the middle, and genocide (kill-em-all) runs tend to be the hardest.
3. Does killing the dummy ruin a pacifist run? Destroying the Dummy does not abort the attempt at the True Pacifist Route and neither talking, nor fleeing, nor boring the Dummy aborts the Genocide Route attempt.

Genocide Route Implications

4. What happens if you play genocide first? When playing the Genocide Route first, you miss out on a lot of interesting stuff that you see in the Pacifist Route, and seeing that lack of things that you saw previously adds more emotion to the experience of the Genocide Route.
5. How many kills do you need for genocide in Undertale? You need to kill 20 monsters here before you fight Toriel; once you’ve reached your quota you’ll get a message saying “But nobody came” and you can then proceed to deal with her – she’ll die in a single hit.
6. What happens if you do genocide twice in Undertale? After a genocide run, you sell your soul to do another run, and the world is erased again after a second genocide run.

Pacifist and Neutral Routes

7. Does sparing ruin a pacifist run? You can fight until you almost kill the characters and spare when they don’t want to fight anymore (when they are trying to flee) and it keeps you on pacifist mode, the only thing that will shift it to neutral is if you kill a monster.
8. What is a soulless pacifist run? Soulless Pacifist occurs when you attempt to do the True Pacifist run but you have already completed the Genocide run, and the only changes are in the very last scene after you chose to either stay with Toriel or go somewhere else.
9. What happens if you do neutral after genocide? The only changes that occur after performing a Genocide route is the change in the True Pacifist post-credit cutscenes, and Chara’s dialogue at the end of another Genocide route, and Neutral routes are the same as before.

Character Interactions and Endings

10. How do you spare Toriel? Toriel has four attacks, although the fight is rigged so that if you’re in danger of dying the attacks will avoid hitting you – the only way to lose is to deliberately run into them, keep opting to Spare her – never attack – and eventually she’ll give up the fight.
11. What happens if you spare Monster Kid on a Genocide run? Monster Kid is not seen again for the rest of the game; it is assumed they evacuated with the others, and if the protagonist spares Monster Kid, they exclaim the protagonist wasn’t particularly bad, this action aborts the Genocide Route, and the protagonist fights Undyne later in Waterfall normally.
12. Can you get Tek armor in genocide? This armor is also the only armor not associated with any of the Human SOULs, to purchase it, the protagonist must first purchase “tem pay 4 colleg” for 1000G to unlock the item, and the protagonist cannot obtain this on a Genocide Route as the option to pay for college is replaced with premium Temmie Flakes.

Game Mechanics and File Impact

13. What happens if you reset before finishing Genocide? If you reset during the Genocide Route in Undertale, the game will remember that you’ve completed a Genocide Route in the past, and the consequences of your actions will carry over to subsequent playthroughs.
14. Is there a true genocide ending in Undertale? Killing every creature and also purposefully triggering every random encounter to kill those creatures as well will get you the genocide ending, doing this will permanently taint your save file, even for future playthroughs.
15. How many endings are in Undertale? Undertale has three base endings that can have variants based on player choices, some endings will also affect other endings, the standard default ending will play if either circumstance for the other two endings is not met, or players have some mix of objectives.
