    I'd be super happy is someone actually drew some artwork based on this one day! I'd absolutely give a shoutout, but, uh, that probably won't do much

    Rantale is a story created by me, Ranny, and it revolves around my OC, whose name is also Ranny. Ranny is the 7th human to fall into the Underground. He didn't fall by accident or being pushed by someone to jump into the Underground. Ranny jumped into the mountain, hoping his life would end there because of the mistakes he made and hoping to escape the feeling of guilt that haunts him all the time.

    A single incident can destabilize an entire timeline of connected events. Like the ripples that spread when you drop a stone into a pond. (This is an Undertale AU.)

    Long ago, two races ruled over Earth: HUMANS and MONSTERS. One day, war broke out between the two races. But... the humans were betrayed by one of their own. The traitor believing that the monsters did not deserve their fate, willingly gave the monsters their soul. With it the monsters won the war easily. They tried to live in harmony with the humans but the humans had lost their will to go on, their DETERMINATION. The humans soon completely vanished without a trace. The monsters now lived on the surface in peace. While they wanted to live with the humans, this was still better than nothing, right? This is a fanfiction/AU where the monsters won the war and humanity went extinct. In this story Frisk still exists but is born into the Dreemurr family as Asriel's twin sister. This is mostly just a fun little fanfic that I made for the heck of it but I do plan to flesh out who the traitor was and what happened to the humans that made them disappear.

    Sans only dreams of a calm and easy life. Not easy when you're the only private detective of an island with a lot of tension. When Ms. Toriel asks him to find one of the orphans she takes care of, it could seem like an easy job. But this human child seems to have been kidnapped... Could the mayor of the city really be the one behind this ? Sans will have to use all the energy he has to find that kid, solve the dangerous complots behind this, and maybe even stop a new war from happening... Undertale made by Toby Fox

    (This story is base on Underswap so yes I kept the last part of the title just put Above since this is doing after the Pacific Route. It can contain spoils from the game too so BEWARE!!!) After Chara free the monsters from the Underground. (They had their issues with humans but they were finally free!) Things were going well for everyone well that is until Frisk decides to return and not after Chara but now wants Sans for some reason. What could that be? Also, Chara will finally realize the truth to Sans about the Reset and timelines of every route. Would Sans ever understand what Chara did or will he hate her for what she done? Read and Find Out! P.S. Yes I see both Chara and Frisk as female to make the story go much easier to understand!

    The story follows Team Hope and Team Void. Two multiversal and dimensional organizations, one good and one villainous, and both rapidly expanding. It follows the story of Shattered Dream Sans, whose desire to create something bigger lead him to create Team Void, with the help of Bill Cipher Sans and William/Error404 Sans from Alphatale. They unleashed chaos and war upon the multiverse, leading to a bigger team, Team Hope who's goal is to restore peace and keep it protected. The story explains how everything once started, how it's going, and potentially multiple endings. It involves the entire Undertale main Multiverse, this includes characters such as Glitchtale and Alphatale along with everyone's fan-favorite characters, because of this the story is very large. There is a wiki for both Team Void and Team Hope in which you can look up the members of the teams and information, and maybe even request your own OC if accepted.
