There is no more rivalry, fighting and wars. Everything is peaceful ever since the truce between the Star Sanses and Bad Guys.

One day they all decided to live together. So Ink creates a mansion in a new AU. The Star Sanses, Bad Guys and many other Sanses lives together.

It was a peaceful day like no other, the Sanses were all relaxing and hanging out in the Sanses Mansion. Suddenly, a portal appeared and they all got transported to another AU.


From there, they are about to meet someone special. Is that someone a friend or foe?

The Alternate Multiversal Traveler (Female CORE Frisk X OC) by adamabyss12

A young boy at the age of 16 had lived an ordinary life. He had a home with parents, he went to school and do his homework, he had friends that he had hung out with, he had a lot of things that he would find the usual normal. While he is a bit bored with the fact that he simply has a normal life, he is content with it, as he prefers normal than something unnatural, due to how chaotic it is, and thus, he lived a very nice life. However, that was soon taken away, when his home had been invaded by an attack from something inhuman, something monstrous, and during the scuffle, the young boy had a form of magic within him, allowing him to escape from his universe, which had become corrupted, before landing in an AU that had not been finished. And during his travels, he will find that he will be needed of aid with his powers, especially since he will be with a former human, now having turned into a entity that exists everywhere, Onnipresent, and now in a war to save the AUs from the fate of the ones that want to corrupt and destroy it. And soon, he will realize what he'll be feeling for this girl.

Imprisoned Love by frost_flames

The Bad Sanses win, and take over the multiverse, one au at a time. Dream and Blue start a rebellion, but their friend, Ink, had been kidnapped by the gang when they lost to them. Now the rebellions goal was to save the artist and defeat the tyrants known as the Bad Sanses. But on the other hand, Ink's goal was just to... hold out long enough to still be him when-or even if-he's saved. He was determined to not be broken by the people he's called enemies for so long, his captors.

Soul Fused by PuppetTheShadow

Nightmare, who has been dead for the last century, stumbles across a dying Sans in a destroyed au and takes him under his wing. Er, tentacles. From there, they start a band of rejects to get revenge on his brother. Sadly, said brother has other plans for them. That wont stop the shakily made team from bonding and having fun though! (AU where Killer is the leader of the 'Bad Sanses'. I own pretty much none of the characters)

A Useful Ally by TheDragonOfBalance

"Flowey returns and everything changes. What even am I? Am I even a human anymore? What if everyone's scared of me? What if everyone leaves me? What if my own brother is scared of me?...At least things can't get any worse. Right? I mean this 𝐍𝐢𝐠𝐡𝐭𝐦𝐚𝐫𝐞 has to end..........or is this only the beginning? This can't be real." The only two characters that belong to me are Emerald and Leo. All characters belong to their respective owners and creators. Continuation of 'A New Place With New Friends'

Fallen (ErrorInk) by stillmirus

I dunno wut im doing, sorry if its bad ;~; Some Background: Most alternate sanses are attending a highschool, call the school whatever you like. This takes place in an AU thats not really an AU, seeing as there are no undertale characters. There is a "Gang" in this school, it is comprised of Nightmare, Error, Cross, Killer, Horror, and Dust. Everyone is afraid of them, except for the Star Sanses. Eventually, one of the star sanses, Ink, is able to befriend one of the bad guys, Error. Error starts to develop feelings for the artist, but, when something bad happens to Ink, error wonders if he'll ever get a chance. {This is an extremely slow-burn! You have been warned.}

The Boy Who Doesn't Speak (Sans AUs) -- BEING REWRITTEN by SKSuperKitty

For some reason, Ink, the Creator and Protector of the Sans AUs, has decided that some of the Sanses of the Multiverse should go to highschool again. Honestly, no one really liked the idea, especially the Bad Sanses, including Ink's enemy, Error. Prince Nightmare is one of the AUs that must repeat these years of treachery. He basically only finished his actual highschool, and is NOT looking forward to having to do it again. Luckily his brother, Prince Dream, will be coming along the journey beside him. But Nightmare and Dream Are polar opposites, so Nightmare can't really get along with his brother's friends, nor Dream get along with Nightmare's, if he had any. With rules to follow and secrets to keep, Nightmare must go through highschool and not let slip the terrible things that happen at home. But then suddenly the two princes disappear. There's no trace as to who might've taken them, either. The only one that doesn't seem concerned is their own father, the king. King Sun-Beam. What is he hiding underneath all of those jewels and fake smiles? A/N: There is lemon/smut. So all you innocent people out there-- don't worry! Because I warn you at every chapter, and right before it happens. I designed the cover, but did the not the amazing artwork of Nightmare Sans. So credit goes to that person for the art. :D Update!!!!: This story is being rewitten. I'm making another book that'll just be this one but a little different. Once that's posted, I'll make another "chapter" in this one, giving a link to the rewrite. Thank you to everyone who still reads or checks up on this book. <3333
