What happens when a genocidal skeleton gets bored of his universe? When his only goal is to wreak havoc on the entire multiverse? To show all of existence no MERCY? How do you stop him?
Easy, you give a silver tongued murderer the power to persuade him to go to the side of the multiverse where there is no MERCY to begin with...

There's nothing to live for anymore. Not even his family can help with this. Or, the people he thought to be his family.
AxeTale - The Full Story
NOTE - I am not the creator of AxeTale nor do I own it's rights, this is my own retelling of the story of AxeTale. A sub-AU if you will, a rewrite of AxeTale, kind of like TS!Swap for UnderSwap, expect this version of AxeTale to be different than the one you know of, as there'll be a few changes here and there- NOTE 2 - I personally am not a fan of Frans / Frisk x Sans... But in this AU both Frisk and Sans are of age, and it's a plot point that they're married... Although I'm not a big fan of this but given the fact it's an AU, that's alright, even if I don't ship it personally, it's a big part of this AU and I have to try to keep it as close to the source material as possible... Just know even if I don't ship it personally, I'm still trying to be at least mostly accurate, small changes aside... AxeTale... An AU from the UnderVerse, an AU with a bleak, and almost hopeless life to it all... But life is life nonetheless... This is the story of a child... Not the child you'd expect to come across, but a deep connection is rooted in this young child... Named Aliza... For she always felt so close to Mt. Ebott, she could not explain why, maybe it's because her mother told her stories of exploring around the old mountain... Maybe it's because Mother told her tall tales about a civilization of friendly monsters, deep under the mountain... On the anniversary of her mothers passing, Aliza decides to follow in her mothers footsteps, to travel through Mount Ebott, with her mothers journal in hand, she will Discover the truth...

FurtherDown
Was this truly the last RESET? Sans wondered. But he knew only Frisk would tell, only this young girl would decide his future. He hated the thought of it at first, but hatred began to grow numb after he figured out he had no say in his own future. He had to admit though, Frisk was pretty reasonable, it was Chara who was the maniac. But she was gone now, so what was the anticipating, eerie, feeling that he had in his bones? The feeling that something wasn't right, of course, this timeline was already incredibly strange. The feeling sat in his in the pit of his stomach, tying itself into knots, until that fateful rainy day when all of his questions would be answered. So basically, this is a fanfiction of a fancomic of the game Undertale. Look, I'm gonna admit, I'm little stuck in the Undertale fandom, so this is my of slowly crawling out of it. Anywho, I strongly suggest you read the fancomic which this fanfiction is based off of, DeeperDown, before reading my story. Here, I'll give you a link. http://gettingdeeperdownwithundertale.blogspot.com/ Anyway, enjoy the story, it took me about 11 months to write, so please consider enjoying it, seriously. - Ya Boi, FoxComplete
