A list of Undertale AUs you can find being updated on Quicksilver and our affiliate pages, featuring one track from each AU so you can find their respective playlists from there. Some of these AUs are updated rarely, but if they're on here then there are still plans to continue them!

Quicksilver's Active AU Masterlist!

Seems like an update to a track called "A New Chapter" would be a proper celebration for our return!

Aftergore is a series of AUs taking place after Undertale's neutral endings, in which a new human enters in Frisk's wake.
Aftergore II, the Betrayed Undyne ending, details an ending in which Frisk ruins their streak of pacifism right before the end, slaying the celebrity robot Mettaton on live television. Toriel has taken her ex-husband's place after his death, and she struggles to maintain morale in an increasingly wary underground. Humans are to be treated not as enemies, but as friends. At least...in theory.

[Aftergore II] A New Chapter

*CONGRATULATIONS, DARLING!
*YOU'VE WON THE OPPORTUNITY TO TAKE A PEEK BEHIND THE CURTAIN!
*THIS IS WHERE THE MAGIC HAPPENS.
*I'VE FLIPPED THIS CREEPY OLD HOUSE...
*AND MADE IT THE CREATIVE STUDIO FOR MY NEW PRODUCTIONS!
*ISN'T IT JUST FABULOUS?

Aftergore is a series of AUs taking place after Undertale's neutral endings, in which a new human enters in Frisk's wake.
Aftergore IV, the Queen Undyne ending, details an ending in which Toriel and the Ruins monsters are killed, but everyone else is left unharmed (other than Asgore of course). Undyne rules the Underground with an iron fist. Humans are to be treated as enemies, not friends.

Mettaton takes the role of Toriel. Deemed to not be taking the fate of monsterkind seriously, Undyne banished him to the desolate Ruins. But when life gives Mettaton lemons, he makes glamorous MTT-brand pink lemonade! He's turned the Ruins into the site of all of his new televised escapades; he's essentially made himself the star of a much smaller production. Sure, it's grossly insensitive for him to do such things at the site of a massacre at the hands of the previous human, but sensitivity shmensitivity, right?

[Aftergore IV] Backstage

The year was 199X.
It was the height of the 16-bit era.
And one company reigned supreme.

Leitmotifs present are:
* Earthbound - Title Screen
* SNES Classic Edition - Main Menu

All rights belong to Nintendo, etc etc.

16 Bits Sequestered is an Undertale AU centered around the SNES Classic Edition, featuring characters/locations from the games pre-packaged with that system. Ness takes the role of Frisk.

Aftergore III, the Exiled Queen ending, details an ending in which only Undyne and Asgore have been killed. Toriel tried to claim the throne, but threats of a coup quickly sent her back to the Ruins. Now the Underground is in a state of instability and semi-anarchy. Humans are to be treated as...well, it's unclear right now, but it's not good.

Sometimes, the Canine Unit can still be spotted in certain parts of Waterfall, looking for their commander. They haven't exactly put two and two together yet. Man's best friend will wait forever to their best friends to come home.

*At long last, two pillars of determination...face to face.
*The queen beckons you to pour all of your heart into this fight.

Aftergore IV, the Queen Undyne ending, details an ending in which Toriel and the Ruins monsters are killed, but everyone else is left unharmed (other than Asgore of course). Undyne rules the Underground with an iron fist. Humans are to be treated as enemies, not friends.

Unsurprisingly, Undyne takes the role of Asgore. With her hero gone, she has furiously taken over the Underground, and rules it militantly. She has vowed to break the Barrier by any means necessary, and strike vengeance upon mankind for their transgressions. The world will come to fear the name QUEEN UNDYNE.

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.

Mettaton keeps his role, and has upgraded Hotland to be the ultimate set for the triumphant return of his acclaimed shows! There will be more drama! More romance!(?) More bloodshed!

(Guest Track - Moikey) [Aftergore I] Improved Medium

*A human, huh!?
*Haven't seen one of you punks in a while!
*The name's Undyne, proud assistant to the royal scientist!
*...don't give me that look, I'm not some NERD!
*My science has EXPLOSIONS! AND LASERS!

Undyne takes the role of Alphys. She's the assistant to the burnt out royal scientist Alphys. Undyne has much more enthusiasm for the job, mostly because having access to a wide range of chemicals means you get to find all new ways to heroically pummel your enemies into oblivion.

[Aftergore I] Suplexing For Science!

Amazing promotional art by @burnedtraveller!

The writeup for Aftergore I will be released eventually-- when it does, this will play at the start of every new section, getting gradually further along as the story progresses. Toadie did a great job making this escalate properly!

[Aftergore IV] Outskirts

This will-- unsurprisingly-- be the last Aftergore track of 2020. Figured this would be a good way to end the year-- a new chapter is upon all of us, with a new year finally in sight.

[Aftergore II] Monster Party

*seems like love is in the air.
*or maybe that's just weird smells.
*alphys hasn't showered in a little while.
*SANS! Why would you tell them that!?

This is Aftergore track 3/4 of the Four Chambers of the Heart Valentines event!

Alphys and Sans share the role of the Royal Scientist. Undyne, keeping the whole underground working at maximum efficiency, needs DOUBLE THE SCIENCE. ...also, Sans wants to make sure he can keep an eye socket on his bro at his new job, so this works out for everyone...except maybe Alphys.
Alphys is the only character you "date" in this particular Aftergore variation.

Muffet takes the role of Undyne, and Waterfall has been absolutely infested with spiders. With Waterfall's main guardian having suddenly vanished, Muffet sees it as a great place for the spiders to expand their business. Go in there with a full wallet, and you'll come out with it being empty...if you come out at all.
