    Being a doctor is quite a hassle, added that you're in charge of your family business. Now you barely have time for yourself, especially the chores around your mansion. You just don't know what to think about your skeletons friends who applied to be househusbands that your friends put up for jokes. ||GENDER-NEUTRAL READER||

    You my Dear Readers are a part of the original Au Undertale. You helped Frisk free the monsters from the Underground. Oh and you also found a way for Chara and Asriel to be brought back with you guys. (Chara and Frisk are boys and Chara is good OKAY? It's the players fault why they do a freaking genocide run not them). Your relation with Frisk is..... well your his awesome Adopted Mother (Cuz your an independent and amazing woman. Hehehe don'tsuemepleasefortheloveofTorielandAsgore). That's why you were with him in the when he fell to the Underground. Anyways You and Frisk live with Toriel, Chara, Asriel and Asgore (yey they got back together for Chara and Asriel). It's been a few months since you and Frisk freed the monsters from the Underground. Your relationship with the others are like family........wellllll except for Sans though he has this BIG crush on you since day one but he didn't have the guts (heheheh get it?) to tell you..... YET. Though my dear readers You and some other people/monsters are gonna be in a BIG surprise of your life. Read the story to find out yeah? Good Luck ~ Rin: My darling Kits I don't own Undertale, Toby Fox owns it obviously. and I don't own the picture in the cover I just edited it and I don't own the mentioned Aus. Anyways enjoy!!!

    Someone appears to be destroying and ripping apart the Undertale AUs... All the hero's have given up, and are in hiding. The thing is, nobody told you. You need to find a way to survive what the most powerful had to run away from, and prove you are strong to end it all.

Welp here it is people, the group chat of all the Au'a that I know of, if u want a Au to be added let me know, also all Au's here are not mine they belong to there respective owners, except for UniversalTale, I own that Au. Also, you can give them a truth or dare question.

    Alterswap, I realize, is a lot like Altertale and Underswap, dubs the name Alterswap. If I hear one comment, "Isn't this Altertale?" I won't be civil. The explanation is right here: In Altertale Toriel becomes short because of her taking the place of mine. In Alterswap she stays the same height and probably weight. As does Sans, etc, etc. ~~~~ The girl fell, she knew she shouldn't have survived. She meets monsters, having this stupid urge to do something rotten, terrible. A thing a human like her would go to jail for if to another human. But the urge came to slaughter each and every monster, for no reason in her thoughts.

    Hewwo! A while ago, I wrote this the old fashioned way (on a fricking peice of paper) and I wanted to share! This is not my AU, nor my characters. I'm just writing my head cannon. BUT, since Soriel (altertale sans x toriel) is cannon for the AU, I may just slip you all some fluff of Sans and Toriel. Okie, see ya! (Not my artwork)

    They say loves is something that cannot be explained. Sometimes it fades, but other times, it only continues to blossom with the distance. This is the case for Sans and Papyrus, at least. (I know Fontcest isn't canon to this au but I'll try it anyway)

    It all started with the sound of a knock, And evolved into a joke, The jokes continued until they became friends, And the friendship turned to a relationship, But soon life came into play, The king came along, Thinking he could sweep the love away.
