Corruption

A long time ago, humans became corrupt. Any normal sort of violence or disagreement between people suddenly became massacres of hundreds. In an effort to purify the "unwanted" humans, scientists grabbed anyone and everyone, legally and illegally, to experiment on. All tests and later experiments failed in restoring humans to what they once were. Instead, a new type of human was created.

Mutated humans.

Monsters.

The names and shadows of the characters remain, but a whole new picture can be painted using the basis of these characters. In this world, all other Undertale AUs do not exist (or if they do, in a separate, inaccessible realm).

It would benefit the audience to know, especially avid Undertale fans, that the characters that I am using have been twisted so that they merely resemble the canon characters. Please do not be angry at me if I disrespect the characters in your eyes.

IMPORTANT: This story will also get dark and sad in some areas. I know that some people are sensitive to certain topics whether because they can relate or it simply irritates them.
You have been warned.

Enjoy!
(I do not own Undertale or its characters, plot lines, anything. I merely take strong inspiration.)
