Doing a Pacifist Route, you promised Sans to never do a Genocide Route again, but little did you know, the demon was waiting for their plan to execute. Chara was never erased fully, as in the next reset, they would commit a genocide route after taking control of you, restarting the DustTale timeline's events, in which Chara kills Sans over and over again, until one day a glitch had occurred, in which, Sans had woke up with all of his past LV. and memories, remembering how you had betrayed and broke the promise you had made him, Sans had went insane, and decided to take measures into his own hand's. Through your way of getting into the Judgement Hall, you began to get an uneasy feeling, as you haven't encountered a single monster all the way through the Underground, which made yourself question on where the monsters had all gone, where did they disappear. Upon entering the Judgement Hall, you call out for Sans, for anyone to answer you, but no one did, until all of a sudden, a monstrous being had emerged from the shadow's of the hall, towering over you, and sending the deepest chill towards your spine, all of the silence then had disappeared upon hearing a roar, echoes through the underground.
BATTLE, START!
