Just Got Back Into FNAF And While Reading Someone’s Story, I Got An Idea For An AU Of My Own.

I had an idea for an Undertale au. I call it ‘Decayedtale’

The basis is that Frisk and Chara swap completely, with Chara now in possession of a soul. Frisk is now the first fallen human and the second prince of the underground. The only ones who notice this are Chara and Sans, due to this version him remembering the resets. (Flowey doesn’t remember Chara because when he was Asriel he met Frisk)

Now both Sans and Chara are anxious because Frisk is nowhere to be found. And they have the right to be feeling that, as the corruption Chara faces at the end of a genocide route is now consuming Frisk completely, leading to the two having to face a corrupted ghost that can corrupt others

The only survivors will be Chara, Sans, Papyrus, Flowey, and Asgore. Everyone else will be corrupted/decayed.

They will have to deal with PTSD, and Flowey won’t be such a jerk like he is in the original game.

The ‘decay’ or corruption starts slow, staying in the ruins for a while. But once it leaves the ruins, it spreads quickly. Chara spends about two weeks with the skeletons before the decay reaches Snowdin. Sans is the first to see what the decay does, as he gets to see a decay!Icecap. He freaks out and tells Papyrus to gather up everything that he wants to take with him to new home. Papyrus asks Sans why he said that but still does it anyway. Chara just stands there, anxious about the decay and what it means. So all three of them pack up everything that they want, and Sans uses a shortcut to take them to the castle. Sans tells Asgore (and Flowey) about the decayed monster he saw, and the king believes him. They prepare for when the decay reaches the capital. They have about 11 days before the decay is at New Home. Then they have to defend it until a barrier is put up around the castle that keeps the decayed monsters out but traps them inside.

I want to write a good story and make good art, I’m not risking it

Said Fable, looking at the person who used to be her friend. But, if she thought back to when they had met, they were never really friends in the first place where they. Now though, she’s not letting them walk all over her. She’s not that naive little girl anymore.

Just as she was about to leave, she felt her arm grabbed fiercely. Then she was turned around and slammed into the wall. She gasped in pain before she started to scream. She had been stabbed right where her hip was. She then had a hand cover her mouth to silence her wails. She looked at her attacker with fear in her hazel eyes, shivering while trying desperately to call for help.

The person viewed as a hero by all gave her a grin, one you would find on someone who had gone insane. “If word was to get out that I was the one was caused all of these problems, I would be persecuted,” they purred, “but if you were to disappear, I’ll never have to deal with that. No big deal.”

Fable was then left there, on the roof of the highest building in the city. Unbeknownst to the people down below, she was the only thing standing in the way of their so-called ‘hero’, and now she was dead.

“I’m just… Done with you! I’m tired of always being called evil for trying to clean the mess YOU leave behind!”

This is Chara’s design, explained as well as it can be, since I can’t really draw them.

Pre-Castle fight has them wearing the exact same outfit as in the game.

After fusing with the KINDNESS soul, the wear the apron and wields the frying pan. They also are wearing their heart locket and is wielding their dagger.

Post-Castle fight, the right sleeve of their sweater is gone. Their arms and legs are littered with bandages, and they have an ace bandage wrapped around their right eye, which has been messed up by an attack.

Update on my au:

The Six Souls also recognized the change made, so when the corruption begins, Sans and Chara will find help from them. I’ll think about what the choice action will be of the eight later on when it comes to that.

Do note that the souls are based off of what I think.

The names I have chosen for the five survivors are Decay, Degrade, Decline, Rot, and Fester. They were chosen based on the nature of my au.

Decay = Sans

Degrade = Papyrus

Decline = Chara

Rot = Flowey

Fester = Asgore

This might be a bit cheesy, but this is the theme of Decayedtale.

Weirdest nicknames go!
