I found some books on Undertale reacting to be completely abandoned and decided to do it myself.

NOTE: This story is heavily inspired by the description from @Dont-Mind_Meh 's book, "Hidden". @Dont-Mind_Meh never fully explored this concept so I'll do it myself. The checkbox never lies. It never does. They weren't that dumb. They CHECKed Error already. His true stats were HIDDEN. But what would happen if it suddenly appeared back? Would the council's perspective change? Or would they deny the truth? (Fgod Concept belongs to Harrish6) Number 1 in #404 - Apr 14, 26 Number 29 in #error - Apr 26, 26

The angels captured a demon for interrogation purposes thinking that because he was near the castle that he worked for the king what they don't realize is that they caught Error the king of demons himself they take him to the king of angels Ink what they don't realize is that they caught him at the wrong time of the month and chaos follows.

Nightmare and Dream where born in two separate Au When Nightmare was born in dreamtale as the guardian of negativity he did not have a brother fate decided to step in there must be a balance so she made another Au and made Dream the guardian of positivity but she accidentally made Dream a vampire what would happen when the two halves that aren't and haven't met before finally meet

Shattered had enough no matter what he did his brother didn't love him passive or corrupted they always fought so he decided to jump into the void ending up in empireverse he tries to keep his head down but is unable to and after a drunken one night stand ends up catching the attention of the king of the moon empire

Dream splashed Nightmare with a potion sci had made they were in a battle. Nightmare fled to undertale he turns passive with no memories after eating the black apple what happens when he is found and Dream finds out that Nightmare was hiding a dark past with the villagers.

Kinda like discord but with the Undertale Aus this will be very stupid

Everything Error ever cared about was taken away from him. One by one. The dust littered the field as the blind judges believed themselves to be victorious. They were far from that. And now Error can't find any reason to stay. He threw himself into the void only to find himself in a very familiar place.

What if thinks went just a little different when Error fell? What if someone really loved him? What if he loved someone even with all his positive emotions stolen?

Error didn't know what to expect after being pushed into the Void. He didn't expect to be transformed into a teenager. He didn't expect to fall into a world full of dragons and a Multiverse stangely curious about him. He didn't expect to find a new family. Damn you Squid! He just wanted to rest with his family! (The cover isn't mine, but I don't know who made it. FGoD Error's concept belongs to @Harrish6. Undertale belong to Toby Fox. The AUs belong to their rightful owners.)
