    Look into the world of the Deltarune: Neko Adaption AU. Where as humans are replaced with the feline likeness that is the neko. Nekos being the commin denominator considering that they're practically the same as humans, despite their cat features. So rest assured, everything is pretty much the same. Other than humans being replaced with nekos. Kris is a very particular neko though...be it nekos are very curious and free creatures. 'The world is your litter box' type mentality. Kris, while being distant and isolated all the time, he often questions this reality and what becomes of it when the world is tasked with not being absurd for once. Nekos are advanced to be of only two genders. Male and female. However, bisexual, trans, lesbian and gay seem to exist just fine. But for Kris? Life is just a large cat kennel that himself and his fellow nekos are trapped in, waiting to be adopted by whatever life's battles may be. And if they do not reach their goal of adoption, then they are put down. Sounds about right. Notes: -Please don't batter me about Kris, Frisk, and Chara's gender okay? This is an AU. I am not doing this as an offense to the canon or any other interpretations of KFC in other media. -Making Kris a guy just makes it a bit easier for me. And to be honest, I can't be the first one to make Frisk and Chara girls. Otherwise, I support everyone and their decisions when it comes to who they identify as. I'm not against LGBTQIA+ in any way. I love you guys. -The cover may look a bit cringe at first lol. I may replace it once the story is done. But it's an accurate representation of what the idea is. Other than that, please enjoy the story. If you hate how I do things, then I will say don't read this story if Kris being gendered as a guy and Frisk and Chara being gendered as female triggers you. Thank you.

    'Its rather funny, how in one universe... Flowers are given a conscience... They're given a life they could live... even if for a short while... Those flowers can dream... Smile... Love... Play... Those flowers... Have one specific dream... To be real humans... They try... They learn... yet they never actually get the chance to fulfil that dream...' 'Yet in another universe?'

Souls matching the very trait they were supposed to represent... Yet alongside being human... They don't live in a dark world... No...' 'they fall down a mountain... All at different times... The infamous Mt. Ebott... Known for having monsters trapped within it... Kept within by a Barrier... These new humans... Odessa, Yelton, Grove, Abbie, Briar, Seth, Florian, and Priya... Each fell down the underground, some at the same time... Some alone... Each unaware of what their fate holds, now that they're human...'

    A Pokémon AU where it takes place after the pacifist route in this version of undertale. Before this story began, a Eevee who fell to the underground from a broken tower was able to free all of the Pokémon that were stuck from it. The Eevee's adventure on the underground was over. But his story wasn't finished yet. His new adventure will start when he and two Pokémon he knows get taken to a mysterious place that seems like a dream. Follow this Eevee on his adventure, and see what will happen to him later on with the decisions he makes.

    A world of superheroes isn't exactly a niche thing. However, this one is unique due to the earth being populated by two races, humans and monsters. While there are not that many superheroes, there are more human superheroes than monsters. This is due to their reliance on pacificism and due to humans being stronger than monsters, most of them decide it isn't worth it. This story will be about Kris Dreemurr, and their friends. This is how despite all odds, and every trial and error they will face, they became great heroes. Cover made by @save0ursisters
