You’ve just completed the Genocide Route, you’ve killed Sans and have shown no mercy to the monsters that you have killed. After you’ve finished everyone, you wake up in a void, someone stands in front of you. They were… human? Human like you. It’s been a while since you’ve seen a human since you fell into the Underground. They smile creepily at you, eyes red.

“Finally… I was tired of being just a “ghost” in your shadows… Greetings. I am Chara. You are with me in the Void…”

They giggle.
