so does this adhere to the belowexchange swaps? (sans-papyrus, asriel-ralsei, gaster/aster-monster kid)

When it’s from silver or toadie you know it’s going to be good

I thought for so long this song was just a fever dream of mine. Thank heavens It's real.

*O-oh wow, a human!
*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

(OUTDATED) Her Final Sonata

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.

I wish happy birthday to Moonstriker with this cover.

Note (07/04/21): Papyrus' design and the track thumbnail have been updated by @the_freaking_weirdo.

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!

[Mortatoriel 1] THE COOLEST INVENTOR, PAPYRUS!! (10 Song Milestone)

*You know, even after losing Mettaton, the Underground has actually been in fairly good spirits.
*It takes a lot of effort to make most monsters lose hope.
*But hey, let me give you a word of advice.
*Don't push your luck.

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 Asgore'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.

Undyne takes the role of Sans. Her house has burned down, her precious guard has disbanded, her crush has mysteriously vanished...she's just about out of hope. Now she works for Sans selling hot dogs, and lives on the Skelebros' couch. Her fighting spirit is completely gone...after all, revenge won't bring anyone back.

[Aftergore II] Passive Aggression

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

Against the Truth

*Please do not upload this song to YouTube and/or any of my other songs or claim it as your own. All unpermitted uploads will be reported and deleted.*

* After everything that you have been through...
* After all of my cruel actions...
* You would spare a lonely, lost soul...
* ...such as myself?
* ...
* What a funny child you are.

We are back from musical hiatus, folks! Enjoy a "Determination" track.

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.

Couple things to note:
1) Although Toriel and MK are involved in this track motif-wise, they do not take any major roles here, considering both of them are pretty much dead (MK's former self, more specifically).
2) Yes, Vio possesses a purple SOUL, with her trait being Perseverance. It makes sense if you think about it. However, much like Clover from Undertale Yellow, the purple SOUL mode functions like the regular (red) SOUL mode - for the most part, at least.
3) In case you're wondering, Chara has a red SOUL.

Deltarune: Switching Suits is @slick_silver's take on Deltaswap. While it has some ties to BelowExchange, it functions as a separate AU. Updates probably won't be quite as frequent as they are with BelowExchange, but they'll happen eventually, so be sure to follow us so you don't miss any occasional uploads :D
