    I have a lot of random Undertale ideas I want to write, but I want to finish "Haunting a Reaper in Training" first, so I'll just write some here. I'll probably expand some of these stories in the future, but if you want to use some of them go ahead. Just let me know so I can read them! Warning: there are ships you may not like. Don't hate. That's all.

    There are two known guardians that watch over and protect the multiverse. Such as Undertale, UnderSwap, UnderFell, etc. These two guardians are named Ink!sans and Error!sans, the guardian of creation and destruction. But, what if there was another? One that is a symbol of Yin and Yang. The Guardian of Balance. One that had more than one part to their soul. !Warning!: There may be some cussing, but it will be censored There may or may not be some gore as well Some grammar mistakes This is my first ever Wattpad story, so please be polite if I get something wrong. They will be just a little OP if you don't mind. A Sans Au x Original Character Story.

    fell held the bag, gripping on it. " are you sure you're okay. " fell tried hard to make it sound like an question, tried. sans sat on the couch, his sockets half opened staring at the television- before sighing lazily. " yeah, i'm good. " -- fell kissed his forehead, while sans continued to lay on his bed. he wasn't sleeping, but his sockets weren't opened. " i'm horrible with love. " fell whispered. " just warning you that. " sans laughed in response, before saying, " hey, you're loving enough. but you're horrible, no offence. but you're just- lovingly horrible. "

    (it is officially now moved!) Classic used to be the god of the underworld, until he was banished by the other gods because of what he is, but except they banished him somewhere else on accident which is earth, and met feera(me) and sannah(oc) and taught him ways of how to be a normal person after a few months later, he met something stranger then ever.... Inspired by:the person who made the greek mythology au Aphmau's dragon video The twilight love story Aphmau's harem roleplay story 'my inner demons'

    Abandoned (it's not even chap 1 yet-) [CLASSIC SANS HAREM] . For all the years he had to survive, Sans never thought that he would be entangled in a case like... this. I mean, the principal of a famous school CAME to HIM of all people! Offering him, inviting HIM to their academy! How could he refuse? Especially after the 'infinite-foods-supplies-without-having-to-pay' discussion (ESPECIALLY that). But still.... Sans tried to think about their purpose. About why they came to him and acting all nice (he's still grateful about the ketchup though. Market this days make it so hard for him to survive). WHY would they invited him? A single nobody who live on streets. To a stray cat (well, MONSTER in his case).... BUT, he can't contemplated it for a long time can't he? There is a life that he has to survive. So, here he is now. Standing in front of his new dorm (his new home). Sans smile a bit. A rare genuine small smile. Finally, he can start a new life. A new start. A new page. A new book. Sans open the door. ◇◈ Hello, dear~ In case you are new to this fandom or didn't know, this is the typical story of Classic Sans going to highschool.... Unoriginal, i know. Hope you are interested enough to click this book. Enjoy it while you can. Fair warning though! My English is sucks. Bear with it. Same case with grammar!~ △WARNING!▲ ▷Profanities. ▷Slow Update! ▷BAD STORYLINE. ▷Errors in English and Grammar ▷Once again, BAD ENGLISH AND GRAMMMAR! ▷DANG IT, PEOPLE! READ THE GODDAMN WARNINGS!! ▷etc... Cover from: wombo.art [Why_are_you_asking] [23 February 2022]

    Ever since more sanses started being created they have all forgotten about the one who started it all.What happens when error finds this broken skeleton and takes him to his anti void and keeps him hidden for his sake.Classic slowly falls into a deep depression. (This story is inspired by a short meme made by Makicutie on YouTube the meme is called "don't forget about me".Enjoy my story) Just a quick reminder! None of the art in this book is mine please go credit the people who drew this on deviant art the only thing that belongs to me is the story. Errors behavior:Error is a bit more calm and sane in this book he learned not to glich out his words when talking to someone Inks behavior:Ink is very focused on making new aus and having party's a bit to much fun to see that classic is suffering Book 2 of: The bad sanses x depressed classic
