Summary
Undertale Multiverse where the Sanses know each other, but with wings. Wings are an extension of a monster’s soul and are typically used as a form of expression or fighting.
Some of the AUs will not have wings, though, since they are technically alternate universes and can be made without them.
Series will consist of (probably) one-shots surrounding the characters, and I’ll probably take suggestions after the first two stories are done. Just because I make a character or relationship one way doesn’t necessarily mean I won’t write something else entirely if I like it, it just won’t be “canon” to the series.

Summary
You hated this.
Everyone in this fancy little café seemed to be staring at you. You could guess why— some random guy who clearly didn’t belong in a place like this sitting in one of the biggest booths they could find? You’d be curious too. It didn’t help that Valerie and her roommates hadn’t shown up yet, though that was partially your fault for showing up early.
------
Just your average harem story, with a fun twist!
or, the author got tired of fem coded gender-neutral reader, and decided to write something for the gays and theys

Summary
What happens when a bunch of different people from across the multiverse get added to a group chat beyond their wildest comprehension?
Chaos. Chaos happens.
(NOTE: This is NOT a rewrite of Chat Throughout the Multiverse, nor does it intend to replace said fic. This is merely a what-if for if one fanfic for each fandom I've written about(in an amount that can actually be added here without me possibly ruining certain aspects of those fics in the future), plus some other fandoms I was intrigued by after creating CTtM but couldn't figure out a way to add them to CTtM without ruining the story, entered the chat instead of the original group)
(NOTE 2: Hazbin Hotel, Fallout 4, Hitman, Gravity Falls, BATIM and Skyrim will all be the original CTtM versions, with slight changes(Gravity Falls will start at the beginning of the series, instead of at the end, FO4 will have Nora survive, instead of Nate, and Skyrim will have a female Dovahkiin instead of a male one, plus the Dovahkiin will be a Khajiit instead of a Nord. Any additional fandoms(Murder Drones, Phasmophobia, maybe more at a later date) shall be the original versions, with slight tweaks based on adapting it to fit the narrative.)

Summary
In a moment of pure chance, two years after the barrier fell and he blinked back into existence, Gaster met a Mage as old as he is...and honestly, wasn't sure what to do with himself. He doesn't do much better at your subsequent run-ins either.
But stars, he just can't stop thinking about you. About what you are, what you can do...the world you both remember.

Summary
I don't have any vague summary.
But essentially, it's Deltarune with Undertale Red and Yellow sprinkled in.
Kris' SOUL is comprised of three souls, Frisk as the Red SOUL, Chara as the Black SOUL, and finally Clover as the Yellow SOUL.
This AU will also feature UT Yellow characters, integrated into Deltarune. Will they have significance? We'll just have to wait and see...
