100 years after the tragic events of Dreamtale, the two brothers continue a war of hate and love. Any AU unfortunate enough to get in the way of the darker brother's path is either conquered or destroyed. Your universe, Recoveryswap, just so happens to be in the most recent crossfire. But with your personality and luck, you may just find yourself on the path you've always wanted. A path of violence, a path of excitement. And who knows. You might be the saving grace for a fallen prince. (It is highly recommended that you read 'Dreamtale: Origins' before this book.) [All characters belong to their respective creators. I am only the creator of Recoverytale/swap.] -Cover Art by Unknown- Book 2 of the Dreamtale Trilogy

Killer AUs are something notorious throughout all of the Multiverse. Hated, but more often, feared by the masses of every AU. You could never tell what was on their mind as they are incapable of properly expressing them because of the emotionless mess they are. And with their reputations for killing whatever they can get their knife to sink into, it was easy to see why they were an "execute on sight" threat. During the events of Ten no Kami breaking into the Multiverse with the intent to conquer it, and the whole thing with Samson shaking reality so violently, nearly fracturing it, one Killer, in particular, fell out of the ruptured reality, falling into something completely different. With no one to lead him, he only wonders what happens now that he can't return. That was, until, he met some guy with a chainsaw...dog?

Reincarnated as Killer Sans but a bit different. First getting reborn and then thrown into a trap AU. Too bed the MC is a genius. (Pun intantional) How that works while the creator (AKA me) doesn't understand shit, is a mysterium. *looks back at MC* But oh well. Wait I didn't give you that power! What in the name of the infinite realms is happening? Read and find out what I can't!

Aster Corvus Concord, now known as Sans Serif Gaster, was living a relatively peaceful life having reached the surface. Then it all reset.

Or will they continue the cycle. Do they even have a choice?

So, I've been seeing a lot of reincarnated as nightmare or nightmare's parasite but they were all good even if they didn't care about killing someone if it could save someone they care about more, so that got me thinking... What if a person with no sense of empathy got reincarnated as nightmare's parasite? WARNING: VERY INCONSISTENT CHAPTER UPDATES. Feeling edgy, might update soon.

As the Villain Sans Squad continues their ways of destroying and ruling parts of the multiverse, a strange occurrence happens. They are all sent to a different world, one where no one, not even Nightmare, Error, or even Error404 know of. What are they gonna do in this new world? Note: None of the following AU Sans's nor MHA characters belong to me, they belong to their respectful owners. Also the storyline and characters might not be 100% accurate.

Fresh has found a way to survive in one body to avoid infecting others and starting a pandemic using Determination. Though he still cannot feel emotions, somewhere deep inside his mind is an obscure loneliness, knowing he doesn't belong. He comes from the other side of the screen, the controlling side of reality where monsters don't exist. But he soon realizes that he is not the only one who doesn't belong, and now he is Determined to save reality.

[art used for cover by Rua Shio! All rights to characters to their creators! Gender neutral!] "You underestimated me, I'm determined too!" "You don't understand, I don't want you to die out there and for it to be HIS fault!" ----- Y/n had been abandoned in the universe they lived in, no one cared for them. One day, a skeleton like the Sans you knew, though dressed differently and possessing a more kind demeanor brought a tall skeleton and two humans to the universe you lived in. Those humans and monsters had changed your life forever. But you would soon figure out you weren't fully human, and the universe you lived in was anything but perfect...

[formerly known as 'I'm Not A Cannibal!'] - Waking up in a strangely familiar place is weird. Realising you've been turned into a skeleton is even weirder. But actually BEING Sans? And not just any Sans, but THIS Sans? Oof, this is gonna be interesting, especially since he doesn't seem to STAY in his AU. - Slight SI-OC!Horror Sans, aka I just threw some of my traits at an unnamed OC, and then threw the OC into Horror's role to see what would happen. - Please note that this story will have ships between skeletons, keeping secret who, and there is something else too, but I don't really want to say what since it would spoil quite a lot of things. (On AO3 it's in the tags tho, so I guess it's been spoiled there already)

When a dog is found in the Underground, Sans decided to keep the Mutt as a guard-dog and bait catcher. What happens when universes collide and this dog... isn't even a dog?
