Horror Sans (not canon, my take)

He lives in the headquarters of his boss, Nightmare Sans. It's large and has two or even three floors with a basement. It's a medieval-style castle, but it's furnished in a modern way. Almost. Well, the kitchen there is completely new.

The horror movie's room has a mini-fridge. There's also a bed with a blanket and pillow. There's a closet with shelves and books. His room is the only one with a TV and a game console, so the rest of his team often comes over to play. There's a desk with a lamp, plenty of paper, and ink. (Note: his handwriting is clunky and not very neat.)

Favorite food is meat.

familiar: Killer is a teammate Dust is a teammate Cross is a teammate Error is a teammate Nightmare is the boss of the team that Horror is a part of. The team is called Bad Guys.

Horror gets along well with Dust for the most part. He communicates well with Cross and Killer.

He went a little crazy after Alphys's suggestion that he overheard in their conversation, and after Undyne's attempt to kill him. He went slightly crazy twice, and is now a little more hot-tempered when hints about the past are made, but is still as kind as the original Sans towards his brother.

His weapon is an axe. Although he has lost his magical power, he is still physically strong and would be no match for the original Sans in a fight.

Due to starvation during the core breakdown period, he always has a good appetite, and if he is not fed on time, he will try to eat everything that moves, even if he does not want to.

(at this moment) He's very caring towards his teammates and loyal to his boss. He still reacts negatively to jokes about his past and still has a good appetite. He'll always support you, but it's best not to leave him hungry. He's a skilled cook in the kitchen.

After the incident with Undyne, his appearance became slightly different from the original Sans.

Sans's jacket has darkened to a dark blue color, with drops of human blood on it. His previously white T-shirt is now gray. He wears black shorts with two white stripes on the sides, and dark pink slippers, which were previously just pink. There's a hole in his skull above his left eye, left by Undyne after the battle. (See?) In his left eye socket is a red eye (bloody) from the guard he killed. His mouth, with large teeth, which in the original Sans are square and large (not like those of normal people), is now more parallelepiped-shaped, and he can open his mouth. He is a cannibal.

A human, a child named Frisk, followed the neutral path. After killing some monsters, including the king, he left the dungeon, but never returned after the reset. Time passed, months passed. One day, the dungeon's core simply broke and stopped functioning. (The core is everything for monsters, like a life support system. It creates food, water, favorable conditions from magic and energy, and filters the air.) Toriel ascended the throne after Asgore and did everything to help the monsters, but many did not like the queen's desire for peace, and Undyne gathered an army and overthrew the queen, sending her to the ruins (the place where the monsters originally lived). The best scientists from all over the dungeon were gathered, and Sans was one of them. He came a couple of times and brought blueprints. He suggested that if they could disassemble the core, get to its core, and repair it, it would work again. Undyne rejected this idea because it was too risky. Two weeks later, Sans overheard a conversation between Undyne and Alphys (the royal scientist), where Alphys suggested launching the core using Sans's magical eye (it had immense power). Undyne didn't want to believe it or try it. Sans was scared and fell into a depression for a week. He didn't leave the garage, studying the core blueprints, didn't eat anything... and went a little crazy. One day, his brother Papyrus finally got him out of the lab and sent him to Undyne. When they arrived, a fight broke out between Undyne and their session, which Sans won. He politely asked Undyne not to interfere with him and his brother. As Sans was about to leave, Undyne launched her spear at him, breaking the back of his skull, and the spear exited through his right eye socket. Undyne inserted Sans's magical eye into the chamber, and the core activated, but Sans didn't die and killed the guards, taking his eye from one of them. He finally broke the core and returned to his brother, telling everyone that souls were unnecessary, and they all now eat people. The end :3 (but now he's on Knight's team)
