This concept is if my character takes the TRUE Genocide route into his own hands. He Kills EVERY monster in the underground gaining 20 LV. Once the human falls into the underground to find piles of dust everywhere, they venture through the whole place to meet Keith in the judgement hall.

"Heh, so ya came after all." He would snicker. "Let's see how well you do with no LV. this time."

The fight begins, and ends instantly, with the game over screen showing up, but once the player presses restart, the screen glitches out, and becomes corrupted. The human returns to the judgement hall once more, but once the fight starts, the human now has 20 LV. as well. Keith will then realized that something is up with the code. When he tries to fix it, his operator permissions become revoked, and the system starts to become corrupted. Keith then proceeds to fight the human, determined to force a restart and reset the system.

Like all AUs, this will become it's own timeline, and Keith goes insane from all the resets, returning to the judgement hall, after he killed everyone.

He is always in his glitched form with full consciousness.
