I have read many reincarnation stories in my life considering it was my favorite type of story to read but none were as cruel and sad as the one I lived. I had died a painful and agonizing death but when I awoke I was somewhere new. I didn't know where till I was told of my new name but this isn't about that or even about my time spent in this multiverse this is about the what is to come. or a story about someone reincarnating as nightmare sans but everything seems to go wrong for them ending in their multiverse eventual collapse. ink and dream were desperate in trying to find a solution to error and nightmares constant destruction and chaos ended up summoning someone from another multiverse in hopes they could help. they did not expect the person they summon to be a version of one of there greatest enemies.

The usual, boy reincarnated as sans, deal. This is a reboot of my previous story reincarnation Tale. My goal is to make the story, writing, and practically everything else better. Disclaimer: I do not own the cover picture. I just colored it the way sans will look later in the story.

A crack opens in a breaking universe and Death peeks through to the other side. It seems like this "code" thing hasn't been doing it's job, and there's someone who's long in need of reaping. Death tries to relieve Geno of his suffering though, well, himself, but when that fails, there's no choice but to relieve his suffering some other way, right? Perhaps they could help each other.

There had been a disturbance in their Multiverse. It was small, so small that only a few noticed it. After a while it just suddenly stopped. They eventually dismissed it, thinking it wasn't anything big. If only they knew what changes were coming, especially for a certain King of Negativity. New yet familiar faces appear and change everything. When the balance is thrown off, how will they deal with it? When a being far greater than any of them disrupts the Harmony in their Multiverse, what will they do? -------•••-------- None of the art or characters belong to me they each belong to their respective owners.

I'm going to experiment with this one. I have a better understanding of Geno becoming Error in the fandom and want to toy with it a bit. What if Geno had Goth at the time that he became Error in the antivoid? How would that relationship turn out? Now Error raised Goth as the only parent Goth knows closely, protecting him from the multiverse outside(especially INK). They work together as he destroys and Goth reaps, determined to help. They catch the attention of many across the AUs, from the gang to friends like Palette or Blue. When Reaper starts to notice the imbalance on the lists, he starts getting suspicious. Will he be able to reconnect and find his family again? Will he be able to love Ge-ERROR again and have Goth as his son? Or is it too late for this family to be complete and has fate taken their chance away for good with other plans? -Based loosely on other ErrorReaper/Destructivedeath content like the Extinction Origin Comic and others so let's see where this goes.

Ink brings them whatever they ask for, witch normally consists of books and chocolate, In return Ink does some tests with Cross. They wouldn't have cared however recently Ink has been referring to them as 'his'. Just what is going on? Should they be worried?
