*How great...for...um...
*Ratings??
*Hold still and smile!
*We'll need to print you a photo ID before you enter the Underground.
*Yeah...that's it...

Aftergore is a series of AUs taking place after Undertale's neutral endings, in which a new human enters in Frisk's wake.
Aftergore V, the King Mettaton ending, details an ending in which Asgore, Toriel, and Undyne are all slain, leaving Mettaton next in line for the throne. He's turned the Underground into an aesthetic corporate dystopian paradise. Humans are to be invited to join his Fan Club. And if they reject it, they die.

A strange talking machine known only as "The Watcher" takes the role of Flowey. Its intentions here seem to be to document Nex's journey throughout Mettaton's domain...or at least that's what it tells you. Why not trust it? After all, if Undertale has taught us anything, it's to ALWAYS trust talking things with stems popping up out of the ground.

(Non-Canon) [Aftergore V] Smile for the Camera

*Here comes the Moonster.

Alcau tells the story of a facility far away from Mt. Ebott in which a new set of monsters is held after losing its own skirmish against humans. After managing to break free from the clutches of Mt. Ebott's Underground, our hero Nex finds himself in yet another holding facility for monsters where his life is at stake. He's quite a few miles off from where he used to be and quite a few memories off from WHO he used to be, but throughout his journey he'll regain his bearings, learn more about himself, and maybe even bring justice to a whole new population of monsters.

Moonstone (@moonstrikefour), sometimes affectionately known as the Moonster, takes the role of Mettaton. He was a mild-mannered guy who never expected to be seen as anything more than an average joe, but his marvelous music and magic made him an overnight celebrity within the facility. He doesn't let fame get to his head, but he's always striving to make his performances more and more dazzling and breathtaking. And a man can only get so powerful before things start to get out of control...

As his Soundcloud account is out of minutes and he's chosen to move to YouTube for the most part, MoonStriker's Aftergore contributions will be uploaded from here on out. If you'd like to hear more from him, I'd suggest checking out his YouTube channel: www.youtube.com/channel/UCEJjFeTJSjV_2DpvpUEfqzw

(Guest Track - MoonStriker) [Alcau] Say My Name

Hello everyone! Welcome to “Deltarune: Switching Suits.”
This is the BelowExchange (@silverswap) take on Deltaswap, only things function a little differently here than they would in a “traditional” Deltaswap take. The “Switching Suits” implies that almost all of the swaps are related to the suits of cards. This means that some of the Darkners don’t swap, and none of the Lightners do. However, it is still connected to BelowExchange via some key story details, which will become more apparent as this project goes on. Though this is technically the last song on the soundtrack, we figured it’d be cool to put it out first because it was the first Deltarune song the public ever got to hear (since it came out with the PS4 version a year before Deltarune).

So anyways…yeah! Updates coming…whenever?

Final note: This will exist alongside BelowExchange, production is by no means stopping on that.

SHOCKING, ISN’T IT?
WELL… POSITIVELY SHOCKING, THAT IS.
HAVE NO FEAR, HOWEVER!
THE SHOCK ORB IS NOT MEANT TO BE DANGEROUS.
THAT WOULD BE QUITE UNLIKE ME TO DESIGN IT THAT WAY.
I… GUESS I SHOULD INTRODUCE MYSELF.
HELLO, HUMAN!
YOU’VE JUST RECEIVED A WARM WELCOME FROM…
I, PAPYRUS, THE GREATEST INVENTOR OF ALL!
WELL, SECOND GREATEST NEXT TO UNDYNE.
REGARDLESS, WELCOME TO SAPPHIRE SANDS!
IT SEEMS YOU’VE GOT A LONG JOURNEY AHEAD OF YOU!
WELL, I WILL GLADLY SHOW YOU THE WAY!
I WILL BE YOUR LOYAL FRIEND AND GUIDE!
AND, JUST A GENERALLY COOL DUDE.

As the 10th track uploaded for this take of Mortatoriel, I figured this would be a great time to upload a track dedicated to the One... the Only... The Great Papyrus!

Mortatoriel 1, the Flawed Pacifist ending, details an outcome in which a fallen human spared and befriended every monster except for Queen Toriel. Former king of monsters, Asgore, has finally returned to the throne after his long exile. Hoping to atone for his mistakes and abandon his declaration of war, King Asgore has instated a new policy detailing that humans are to be treated fairly, with kindness and friendship.

Papyrus keeps his Underswap role. This cool dude has been given an exciting new job by royal scientist Undyne - he's now Sapphire Sands' local inventor, and Undyne's assistant! He aims to help everyone out much like Undyne, in addition to guiding the next fallen human towards a peaceful journey in the Underground. After all, the last human verified one of his key beliefs - everyone can be good if they try their hardest!

*I can't lie to you anymore.
*I can't stay silent about how I feel.

Against the Truth

*BROODING SECTION
*No talking allowed!

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.

Napstablook keeps their role. When Mettaton was banished to the Ruins, he took Blooky along with him so he wouldn't be lonely. Napstablook didn't want to leave the family ranch, but they also didn't want to disappoint their cousin. At least Mettaton gave them one "quiet section" in the Ruins where they can brood in relative peace. What a thoughtful cousin.

*FRIEDEN - ATK 40  DEF 40
*Just wants everyone to be happy.

Alcau tells the story of a facility far away from Mt. Ebott in which a new set of monsters is held after losing its own skirmish against humans. After managing to break free from the clutches of Mt. Ebott's Underground, our hero Nex finds himself in yet another holding facility for monsters where his life is at stake. He's quite a few miles off from where he used to be and quite a few memories off from WHO he used to be, but throughout his journey he'll regain his bearings, learn more about himself, and maybe even bring justice to a whole new population of monsters.

A well-dressed dragon named Frieden (@user-255285003) takes the role of Toriel. He lives in pretty much complete solitude in the long abandoned Z-Sector of the Alcau facility. He tries to be the best friend he can to the few monsters that DO live in the Z-Sector, but for some reason everyone is afraid of him. Maybe it's just how tall he is. Or the scar. Or the military uniform. Who knows?

swapshift - An Emotional Story (OST 1)

*Oh ho ho, you do not owe me one penny, Mr. Kittyson!
*The smile on your face is payment enough.
*It may not pay rent, but it warms my heart.
*What more can a man ask for?

This is Asgore Dreemurr's Phantom Crown, the story of a single dad down his luck being dragged into an alternate dimension to find himself.

This takes place in a Deltarune timeline, where Asgore owns a flower shop in Hometown. It is heavily based on Deltarune in many ways, but it does not have "roles" or "replacements." This is an original story.

This is Asgore's theme, which will play at various important points throughout the story.

Not every song will be a calm take on ASGORE, don't worry. Plenty more on the way...eventually.

Nice Day Today

Here's a little track to kick the project off, nothing huge.
Taleshift was an AU made in 2016 by Kain222. We'd say it was pretty ahead of its time, considering the sprite comic made it all the way to Waterfall, which wasn't very common then for AUs like this. Honestly, it still isn't. Sure, some parts of it were very generic and other parts...haven't aged all that well...but it's still commendable for what it was, especially at the time it was made, early in the fandom. Very few tracks were ever made for it, and none of them were made for Asriel. We'd say this could also work for Twistedtale, but Twistedtale actually HAD its Undyne replacement made (before it got taken down, please come back Zero ;-;), so we decided it would be for this one instead. We haven't heard from Kain since they said they were moving houses four and a half years ago, but wherever they are, we hope they're doing okay.

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!
