What happens if you do a Genocide run before a pacifist run?

If you do a Genocide run before a Pacifist run, you will essentially lock yourself out of a “true” True Pacifist ending, as the game will end with a sinister cutscene implying you’ll kill everyone anyway, and even a True Reset can’t erase this outcome. This means that attempting a Pacifist run after completing a Genocide run will result in a slightly altered ending, with a different character expression at the end, but not a completely different ending.

Understanding the Consequences of Genocide and Pacifist Runs

To fully grasp the implications of doing a Genocide run before a Pacifist run, it’s essential to understand the mechanics and outcomes of both types of runs in Undertale.

Genocide Run Implications

A Genocide run involves killing every creature in the game, which permanently taints your save file, affecting future playthroughs. This run is considered the hardest to achieve, as it requires killing every monster and triggering every random encounter to kill those creatures as well.
