Insanitysans Stories

A Story of Fights from Undertale. (AUs included)

Sans has become insane, and decided to kill the multiverse after he became bored with resetting and killing his friends over and over again

You and your brother Sans remember the resets but no one else. You go to Dr. Alphys lab to make determination. But the experiment goes horribly wrong affecting you and Sans. You managed to stay longer sane then Sans does. Sans then kills everybody and you hide. the one day some bad Sans Au's meet you then more later on. They then take you and your brother Sans with Papyrus's head is Determined to find you. And kill anyone in his way.

Classic is from a really normal AU. The other AUs are much more stronger than him. He would probably dust if he tried to fight anyone of them.. But what he realised was.. he was more than what he thought he was... The True King.. The cover art doesn't belong to me. It belongs to MsShadowFlower on Deviant Art. (I think)

Ink is becoming desperate as the clock ticks down he finds something no fictional entity should have the wiki, now with this power within his hands ink will finally set things as they should be true peace After an attempt by an unknown tried to take over her body murder!sans finds herself thrown into the multiverse without any warning and it only gets worse when she gets the eye of a lot powerful people Luckily she's not unprepared as new places with god like enemies means new reality warping powers, she's just untrained Ark one the obsessed monster

These are just some Undertale Au's that I've made with the idea of making something new or remaking an Au that tbh makes no sense (or has "Good" lore) Mind you these are just my ideas and i really only work on these if I'm motivated If there is any artwork i have done for the au i will show it off (Mind you i make none of the artwork shown in this. I have terrible at art. (more might be coming) I also will try my best to update this every Sunday with either new lore/updates

Endless breath but Dust sans The first chapter is a from October 16 2023

A redo of my story on my Z-Mixed account because my phone broke, so I had to remake it here

If you find a god of time call don't trust him, instead stab him; even if doesn't kill him! -Refund|cost

I got another shot at and I thought I'll be fine and live a peaceful one but nope that dream was crushed when accidentally blow up a planet now I'm fighting the garden and creator of au's while avoiding a deity that somehow fell in love with me.

This is my first story so I don't think It will be great. Anyway This is the story of mainly Classic and Red. After a huge glitch in Classic's timeline, The barrier finally opened. Everyone was safe and in utter joy, But the glitch affected one person. Frisk was laying on the ground no longer moving. Although she was still alive. Toriel was not taking this well. Asgore managed to calm her down. Everybody left the barrier. When they stepped out of Mount Ebbot. They saw several people that looked exactly like themselves but in different clothing. Looks like all the Aus are free as well. None of the images used here are mine! Except for the Jacket and collar design and Gacha club outfits! 3 years later~ Everybody seemed to have settled in. Some Of the Aus are pretty violent though. After coming to the surface Classic is starting to go to Highschool. Why? Because of papyrus. Papyrus along with temmie are going to Toriel's school. Classic came along with papyrus to left him off at school and then go to Highschool. Oh his way they bumped into someone. Guess who they might be? (Forgive me for spelling mistakes and bad grammer)

Y/n. a man who was obsessed with beating the most difficult Undertale fan games, he adored many animations such as satsujinki sans. but what if Y/n was transported into highschooldxd with the powers of satsujinki sans and the minds of all four sanses. let's find out then together......

Cover is for the second arc of before multiverse: reneged a totally normal reborn as chara story

(All of the characters are NOT mine. respective owners are: Ask-Dusttale And Zero Danteero.) The year is 201X on MT EBOTT... You already know that, You have cheated the world thousands of times with resets... Sans was aware of this but something was REALLY different this timeline.

The actual story for the verse

True Dust and his rag tag group decide to do a study on the Multiverse, while different groups a fighting each other for the fate of the Multiverse. This is apart of the aligned Multiverse

Really big trigger warning here! There are many descriptions of gore and blood, and if your uncomfortable with that, please do Not read! Also, this isn't dusttale, nor is it Last Breath sans,It's a completely different au where Gaster tries to inject sans with something to make him stronger, and well, you'll find out ;) This au does not belong to me!
