When Worlds Collide by VaultBoi reviews
(I started this a while ago and uploaded the first version of the first chapter on another account and have since lost access to that account. I’ve changed a lot of the story since then.) Sans, Frisk, and their AU variants discover each other’s worlds and end up on a high stakes mission to get a valuable item back from a rather dangerous and uncooperative version of Sans.

No Weakness by Theta and Koscheii
[Underfell AU] Undyne is weird, and Papyrus doesn't like it. But by the time he tries to understand why, Undyne gives him the lead of the Royal Guard and disappears from his life. But why? Papyrus investigates, as some people try to dissuade him too. Probably because all the tracks are leading to Asgore, and that if he doesn't give up, he might lose way more than his job.

Undertale: The Royal Hunt by HowManyJays reviews
"The little girl just could not sleep because her thoughts were way too deep, her mind had gone out for a stroll and fallen down the rabbit hole." - A life of fear is not what Frisk ever expected to have. - Warning: this is a dark AU that tackles mature themes and is not recommended for sensitive readers.

Scarlet Knowledge by jumbochamploonrules reviews
After getting through the entirety of Undertale and Undertale Yellow, the latter being able to be beaten on every route, Scarlet Johnson wakes up from a slumber to find himself in the body of Frisk and being joined by Chara. And after learning he's in the Undertale universe, but with nods to Undertale Yellow, he needs to get through or die trying. T rated for language and innuendo.

Sol Reapa one-shots by alexmarch097 reviews
just a few one shots for my OC of ErrorSans, Sol Reapa. one of the few known as a traveler. that means Sol can move though the void between multiverses. I have expanded this to an ability to move around the entire multiverse, regulating undertale AU multiverses to a 'pocket verse'. this way it is easy for him to go to other fandoms. so large crossovers will happen.

Pafriskus: What's Boning On? by The Bohemian Rhapsody reviews
Basically a literary port of a YouTube video, which itself is a parody of the SLACKICiRCUS techno cover of the song by the 4 Non Blondes. Papyrus accidentally absorbs Frisk's soul, and, now bursting with DETERMINATION, grows fabulous hair and cannot hold his urge to SING! (sh!tpost)
