GameChanger, a roleshift that I would consider to be one of the classics. Never got enough love beyond "oh Sans and Muffet swap" imo, so here's something for Asgore, who took the role of Mettaton. We don't know if GC is ever coming back, a scrapped unreleased track was released by its creator very recently but prospects are looking bleak for the AU itself.
This project does involve us doing a lot of guesswork, so this is our theory for how the "musical" segment would go with Asgore in GC, with Asgore giving a heartfelt monologue about how the Underground got to be the way it is.

Operation F.I.G. (short for Filling In the Gaps) is a project run by @slick_silver that aims to show some love to AUs that have either died or have been dormant for a long stretch of time by making music that never got to be made for said projects before. Many of these will in one way or another be speculative, and all tracks on this page are non-canon / unofficial unless the AU creator decides otherwise. If you are the creator of the AU and would like this track taken down for any reason, let us know and we will comply. Our main rule is that we can't do tracks for old projects run by members on the team, so this is all out of appreciation for others. If you're a musician (or artist) who would like to apply to be a part of our team, shoot Slick a message on Discord at Slick Silver#8818 .
Have a wonderful day!

This replaces "Lancer" in the second of the three variations of Schreibertale + Deltarune, known as "Whitefire." This one's for the college experience of Eric (aka Dusty), who replaces Asgore in Schreibertale.

The excitable and adorkable Chance takes the role of Lancer. More info on him later.

Inverted Fate - PAPYRUS! (Cover)

Community is a great show and you all should watch it.
It's one of my favorite shows ever, and once Toadie finally saw it, it became one of theirs too. So naturally just like everything in my life I found something I liked and turned it into an Undertale AU. Updates will be infrequent but they'll happen-- Toadie and I would love to make this into a thing.
It also has a real banger of a theme song.

Toadie and I collabed on the logo! I think it came out quite nicely. Simplistic, but good!

Side note: Toadie fucking INSISTS that I should have called this Greentale. The only compromise we could reach is that I had to admit that in the description.

“You cannot fight what you don’t understand.”
An updated theme for a new boss in the Flooded Temples. This one took a LONG while to come out due to lots of technical difficulties in terms of mixing, but we've finally got the issue resolved and can continue our regularly scheduled program.

Dapper Bomb!

So what is Spadeflush? Spadeflush is basically Deltarune's Aftergore. A return to the Dark World very soon after the events of Deltarune.

Now Slick and Toadie, I hear you cry, isn't Chapter 2 of Deltarune going to negate this completely?
Well, possibly. But possibly not. This is meant to serve as an alternate course of events as opposed to Chapter 2. I know that Deltarune being unfinished makes people having mixed feelings about Deltarune AUs, especially ones like this, and I completely understand that. For now, we can just enjoy this for what it is, and worry about the rest of Deltarune when we get there.

Spadeflush has no ANOTHER HIM replacement, and instead starts with Before the Story. So here that is.

Howdy, everyone! I wasn't lying when I said I would be coming back from my long hiatus. Aftergore is a pretty big AU currently, so I thought I'd contribute some love and support for the AU. This is my 10th song cover, as well as my first ever "Toriel" track (specifically, a track that revolves around Toriel herself, not a Toriel-styled track like "His Hopes"), disregarding an unreleased "Fallen Down (Reprise)" cover. Enjoy!

A quote from Slick Sliver:
"Aftergore is a series of AUs taking place after Undertale's neutral endings, in which a new human enters in Frisk's wake.
Aftergore I, the Incomplete/Flawed Pacifist ending, details an ending in which everyone (except for Asgore) was spared and befriended. Toriel has taken her ex-husband's place, ruling the Underground with both strictness and kindness. Humans are to be treated not as enemies, but as friends.

Toriel takes the role of Asgore. However, she does not hide away in the castle for the whole adventure. You can find her at her very own school in Snowdin Town, where she's happy to see you! Surprised? Remember, her policy is to treat fallen humans not as enemies, but as friends!
She wouldn't ever do anything to hurt you...right?"

Alright you know what they say, third time's the charm. Let's hope I don't lose too many minutes this time. You know the rules people, no need for me to reiterate them. But for those who never heard of me before and what not, lemme just do it anyways.
Welcome to my humble abode. If you want to use my tracks for ANYTHING, I would appreciate it if you asked me first before using it so that way I know what you're using it for and not claiming it as your own and all that jazz. If you're not gonna ask then AT LEAST give me credit. I don't appreciate thieves and at this point I'm pretty sure no one does. 

And yes, you are allowed to upload my songs to YouTube if you want to. Just don't steal, all I ask is that you give proper credit then we'll be cool k? Alright then.
