(You were a fallen human, the 7th to be exact with whatever SOUL Trait you even had, anyways, genocide has fallen upon the Underground due to you continuing your ways of Genocide. Sans had enough and took matters into his own hands, killing half of the Underground, and even his brother as well, to compete with your power. But now, everything's different as you enter Judgement-Hall, you walk for a minute in the long hall until you see Sans in the distance, you look at his and notice a few things; behind Sans is a large bag filled with items, he looks calm for now, but eventually, as time goes on he will become nervous but for now, he's calm. He looks at you with a wicked smile as he faces you with his left eye glowing red and his right, blue.)

DT-Sans: "It's time to end this, kiddo!"
