What are the 20 endings of undertale?

In fact, there are only three endings in undertale, namely, the perfect ending (PE), the general ending (NE) and the massacre ending (GE).

1, the last BOSS in the happy ending is Asriel dreamer, his father is Asgor dreamer, that is, the penultimate BOSS in NE ending, and his mother is Torrell. You can't kill it, but if you die, you will be RUFULES THE DEATH and play the game again according to the current process.

2. The last BOSS of the general ending is Omega FLOWEY. You need to go through the baptism of six souls before you can overcome it. If you die, the game will crash, but your soul will be stored.

3. The final BOSS of the massacre is SANS, and you need to go through his trial. In the middle, he will forgive you. If you forgive him, be prepared to be covered with hot pot. If you choose to attack, he will say: Yes. It can be understood as "ok" or "right", because people's hearts are biased to the left.

Undertale's game background;

A long time ago, the earth was ruled equally by two races, namely, humans and monsters. One day, the drums shattered the peace between the two sides; Under the aggression of near-slaughter, mankind has won great victories. Humans banished the monster to the underground world, and seven wizards set up a rather powerful magic barrier to trap the monster in the underground world.

People can enter the lower bound at Mount Ebert, but they need at least a human soul and a monster soul to leave the lower bound. Before the story began, no one left the lower bound alive, which led to rumors that the climbers on Mount Albert had left and never came back.

The monster is trapped in the underground world and ruled by Asgard Drummond. After the monster dies, the body will immediately turn to ashes, without soul and body. Monsters' souls are far less powerful than human beings.
