Before Erwin, Levi "bonded" with someone else. She will always be Erwin's little sister first, and anyone else second. And her smile—oh her smile—dares Levi to fall in love with her.

Dancetale AU, a few years after the Pacifist ending of the game. When life is this hard living among humans, there isn't much time to dance. Sans has nearly forgotten the feeling of moving to a rhythm at all, but she enters his life and reminds him how. Descriptions of OC left vague for a semi Reader experience. Dancetale idea belongs to teandstars on Tumblr.

War is where both sides believe they are right. Arthur, born from the Underswap AU and threw into the OriginTale AU must survive as the world crumbles around him, war settling through his telling of his Origins.

When Flowey throws famous YouTuber Sean Feelgood right into Undertale, the sixteen-year-old is faced with the enormous task of completing the game's Pacifist run... but in real life. Luckily, Sans, Papyrus, Undyne and all the rest are there to fill him with Determination. The only problem is that Sean was never able to beat Flowey, not even when Undertale was just a game...

Falling is a strange sensation. But the landing is worse. Especially when you suffer from anxiety and a fear of death. But maybe a certain skeleton is just what the doctor ordered? Bad summary. sorry. -the oc is the reader ... not all chapters will be as short as the first one, its just for dramatic effect!
