It tells the story that the player directly returned to the ground after killing MTT and Yang's father, and there was a panic underground. The death of MTT brought great psychological pressure to Zhai Long, and she committed suicide. Sister Yu went crazy when she saw Zhailong commit suicide, but because there was no leader underground, she chose the captain of the Royal Guards.

Second, under-fell (under cruelty):

The monster here is just the opposite of the original. Basically all monsters want to kill you. Papyrus is the kindest in the original, and the plot here is similar to the original.

Third, muder—tble (under the dust):

This is definitely the most worrying AU for me. After the slaughter of player 25 1, Sans finally woke up and decided to get exp himself. That is to say, he wants to improve his LV (love) by killing other monsters, become stronger and beat the players.

After killing one monster after another, although Sans finally decided to kill papyrus, Sans went crazy and created a papyrus with only head and hands in his mind, but even so, he could not resist the "power" of the player.

Extended data

In Undertale's story, Sans is Papyrus's brother and made his debut in the forest outside Snowtown. Depending on the player's actions, he will become a trusted supporter or a terrible opponent like a hero. He's the ultimate hero of the massacre route? The game is extremely difficult.

Sans always grins when he speaks, and rarely really "moves". He has white pupils, which disappear when he is serious. When you play against him, his eyes will flash blue and yellow like neon lights (because the second set is called the eye of judgment by the majority of players). At the beginning and end of the battle, when gravity control is used, there will be obvious flashing.
