Xéno!Sans

**Xéno!Sans** is the Sans of Xénotale.

## Story

### Backstory

At one time, everything was fine, but one day a "human" beat Undyne. Papyrus then entered the royal guard and became the master of Snowdin. Sans was scared of his brother and couldn't drink ketchup anymore.

### Neutral

Toriel contacts him and tells him about Frisk and the threat she is. He reassures her by saying he will make her killed. He meets Frisk and teleports her at Toby Fox's, but he fights her and causes a landslide. Sans teleports Frisk somewhere else and disappears. He tells Papyrus that a human is in Snowdin. He reappears to help Frisk, by giving her clues or by preventing her. At one point, he asks her to kill his brother, as well as freeing Toby Fox and Gyftrot. He helps Papyrus to trap Frisk, then speaks to his brother after his defeat. He ends up being tortured by Papyrus in the basements of the Underground.

### Eidocide

In eidocide, after the death of his brother, he began to be afraid of Frisk. He trained then to become stronger. Then Zeno arrived and trained him. Sans died thousands of times. Then came his fight against Frisk. The first phase was going normally. He took an attack but he resisted. An energy enveloped him and he became stronger. He took an infinite damage attack and died.

After Papyrus disappeared, he took Frisk's soul. When Papyrus came back, he fought him, and though he damaged him a lot, he died.
