My top 10 versions of Gaster's Theme. 
Note that despite Soundcloud's numbering system, the #10 pick is actually the one below the original, and the #1 pick is at the bottom. That way it functions like a countdown.

Some rules apply as always:
1. The song has to be for an AU.
2. Covers and takes are allowed, remixes are not.
3. Only one entry per AU. For example, a song and a cover of that same song or alternate version for the same AU could not both be there.
4. Any variations of "!Underswap" (or !Underfell or whatever) all count as the base AU (i.e. Underswap). (Something like Integrity or Undertale: Swapped, however, could coexist on the list)

Slick's Top 10 AU Gaster's Themes

Fivenightale is my own take on the "FNAFtale" concept, crossing over FNAF characters into the Undertale story formula. Frisk is replaced by Eggs Benedict, a late-night technician who works his way through multiple Fazbear locations, where he encounters various possessed animatronics and other supernatural occurrences that stand between him and his paycheck.

Toriel is replaced by Henry, the secretive but well-intentioned businessman and guide and Fazbear Entertainment cofounder, who helps Eggs get the basics of working the night shift. If Eggs has accomplished everything Henry requested of him (i.e. true pacifist route criteria), he will follow him to the New Pizzeria, interrupting just before a fatal moment.

This track replaces Fallen Down (Reprise).

- Alchemist's Fantasy (Leon Riskin) (Tutorial used as reference by Pianthesia)
- Original? (idk I just riffed to the chords)
- Underneath (Leon Riskin) (or at least another random riff that's supposed to resemble parts of Underneath)
- March of the Toreadors / Overture (Georges Bizet)

021 - In My Own Words

Check it out on YouTube: https://youtu.be/U9h8RmWN4sU

===== DIALOGUE =====
* CHAIRIEL - ATK 15 DEF 10
* Attacking it has no use.
* TORIEL's defenseless like this.

===== NOTES =====
Unruly is a Deltarune AU inspired by and building on the original premise behind "Placed Bets" that explores the consequences of removing a given Dark World's ruler, boss, leader, etc.. 

In Chapter 3 (technically before then) we see Kris turn on the TV before they plunge their living room into darkness. 

But what if they hadn't done that? What if they couldn't? What if the TV had already fallen into disrepair? And what if the beloved living room chair... started causing problems?

--

It's finally time for the first of TWO scheduled new followups to the Placed Bets saga, and alongside this I can say I actually put a bit more thought into how it all "works" enough to make it a "proper" side-project! You might end up seeing more songs for UNRULY popping up in things like the music polls and other such events.

Track made as a (very old) request for Cacote/Aster
Requests not open unless I ask you for one.
Dialogue based on an AU of mine that I felt this concept fit

M: Well, darling, I'll admit it's been fun...
M: And you've well established that you're no threat to monsterkind...
M: But you certainly are one to humanity, and we just can't have that, can we?

C: ...so it's come to this.
C: Fine.
C: If you insist on standing in my way...
C: We'll find out firsthand if those defenses are any better now than I remember.

Entry Number 17
* I can feel the heat rising
* The fire is everywhere
* It burns me inside and out
* But I know that this is how it must be
* Those who take no risk aren’t the ones who change the world
* But once I’m done
* The whole world will feel my hellish wrath
* But let the record show that I’m not evil
* I only want a better world for my children
* And the only way this world can be better
* Is by starting over.
