"Wow, Shiny, you're uploading the Ghost fight replacement before the ruins theme or the Fallen Down replacements are up?" Why, yes. yes I am. A very special thanks to @dustpotato for this contribution, by the way!

In Disbelief: Aftermath's Branch 1; Mad Dummy takes the role of Napstablook in Branch 1. Being the Queen's former training dummy, they were let into the guard! Because they're incorporeal, they're usually sent on stealth missions, even if that plan usually backfires due to their loud personality...

This literally took me 10 minutes to make.
Undyne's replacement is a certain lost soul, bent on revenge.

The boss theme for the end of Fort Aquarius, against Dohj (based on the cut character Doge). Credit to Timber for the original Dohj motif and to Yoshimo for inspiring part of the arrangement. Also special thanks to Nano/Doctorine for helping with the drum mixing.

This song is mostly original, but does feature a little Alphys toward the end.

ANIMATION IS FINALLY OUT!

https://youtu.be/aw2hfcnsIO4
─────────────────────────────
Finally, The Castle trio animation is now complete, and with it, its music too.So here you have folks Against the castle trio V2!
I really don't know why but V2 took like 2 months to do, and its not even THAT good, this could easily be made in less than one week if you put effort on it, but the main reason it took that much is probably because at one point i lost motivation in finishing it, Still, am really glad i could end it at one point!
─────────────────────────────
Sooo, what's going to happen now? That's easy, The Castle trio Took a LOT to do, the project has started on May 2019, so i guess it's time for a Short vacation, Yup! I wanted to say this in a video, but in a few days im going on some short vacations, 15 days kinda, after that, i REALLY would like to jump into music, once again.Next track, is the one, the one that started it all in my channel, a cover i REALLY want to do, finally EXELOVANIA 3 years of youtube edition, it may took a while to be honest, i SHOULD publish it on 3rd march, but this vacation are surely gonna make it impossible to do so, expect it to be between March or April!

Anyways, hope you like this track and see you next time

You can use my music if you want, i would love to see videos of you using my content! But, still, you CAN'T reupload my songs
By reupload i mean a video with NO effort put into it using my song.
If you are unsure about this reupload thing, and you don't know what you can do with my music, well, you can ask me in the comments, i'll try to answer you!
─────────────────────────────
Now have a good day! And try to play some cards games with your friend, they are pretty fun!

YA PUEDES VER LA ANIMACIÓN
https://youtu.be/aw2hfcnsIO4
─────────────────────────────
Finalmente, la animación Castle trio, por fin fue terminada, y con ella, también su música.Así que aquí tienen muchachos, Against the castle trio V2!
No se porqué, pero la versión 2 tomó mas de 2 meses en hacerse, y nisiquiera es TAN buena, tranquilamente uno puede hacer esta canción en menos de una semana si se lo propone.La razón principal probablemente sea por falta de motivación pero, estoy alegre de que pude terminarla algún día!
─────────────────────────────
Entonces, que pasará ahora? Fácil, tomaré un descanso de 15 días y luego volveré a la música, o por lo menos eso intentaré, probablemente la próxima canción que siga será, EXELOVANIA edición 3 años en youtube, así es.La canción debería salir el 3 de marzo, lo cual será imposible debido a las vacaciones que tendré, así que probablemente salga entre marzo y abril

De todas formas gracias por escuchar, y espero que les haya gustado el video!

All the leitmotives are from "Your Best Nightmare" if you still can't tell. The 2nd part is from the unused part of it and heavily modified, though the rest is mildly modified as well. Again, it's a fan-track if not official.

[Undertale AU][Swapped Rhythms] In Times Gone by...

Undertale by Toby Fox
Swapped Rhythms by FwugRadiation

*In times of yore, two unique kinds were risen to care for the EARTH: HUMANS and MONSTERS.
*In the aftermath... it became the worst nightmare for both of them.

FwugRadiation - SWAPPED RHYTHMS Soundtrack - 01 In Times Gone by...

AnrisTa's / Solunary's!UnderSwap - INCINERATION v1 (Reupload)

Deepertale is an AU that takes place in the aftermath of a nearly complete Genocide Run. Alphys has hidden all the survivors in the True Lab. Flowey was the only one who got in the human's way and lived to tell the tale (and that was by escaping within an inch of his life). The human has chosen not to erase the timeline yet, and walks the dusty Underground while down further below the monsters cower in fear.

Deepertale is considered to be a satellite AU of the Aftergore series, the Discord server of which can be found here: discord.gg/WbzykND

[Deepertale] In Memoriam

toby fox - death by glamour

* Oh? I thought I heard something!
* Why, howdy! I'm Flowey. Flowey the Flower!
* Say, you came at a really good time, friend; because I need your help!
* Don't worry, I'll help you in return, you must be pretty confused, right? I can teach you how things work around here!

Special thanks to DustPotato [@user-269404932] for this contribution! And another thanks to Yertendo for helping out with the flowey sprite, That's a cute ribbon he drew lol-
---
In Dısbelief: Aftermath's Branch 1; Flowey keeps his own role, albeit that doesn't mean he hasn't changed since the last time a human has been around. With how the Underground is barely staying united, A human is just what Flowey needed to satiate his curiosity...

Special thanks to @moonstrikefour for this contribution!

Branch 1 (titled "The Divided Underground") details an ending where the human abandons their plans of genocide after their confrontation with Sans in Snowdin. They treat everyone they meet from that point onward with kindness; leaving monsterkind divided on their opinions about humans. With tension among monsterkind rising day by day, and with Queen Undyne's attempts to reunite monsterkind continuously failing; how will the underground react to a new fallen human?

Hey, did you like that short jingle? It’ll play whenever a character joins your party. @dashingtoadie-the-sequel was the one who made it! Many thanks to them!

Right! So, let’s cut to the chase; WE HAVE A NEW DISCORD SERVER! While operating in Aftergore’s server had its advantages, it ultimately caused a lot more inconvenience. So, we decided to move to a separate server!!!

If you don’t know what Disbelief: Aftermath is, Disbelief: Aftermath is a series of Undertale AU’s inspired placed after the events of Undertale: Disbelief; in which a new human falls down, after Frisk’s rampage through the Underground. In Disbelief's original story; after Sans' confrontation, the human continues their massacre; completing their genocide run when they kill Papyrus. But what if they didn't? What would the fate of the Underground be if the human took a different course of action after Sans' death? This is what Disbelief: Aftermath hopes to answer.
