In Destiny Neat, we will follow the journey of Jadsen, a monster from the surface, crossing the magical barrier that protects humans from monsters, discovering a new world hidden within the mountain.
In this version of Underswap, we will face the various bosses from the original Undertale, but in the reverse order. There are really only two essential changes for this version:
Asriel Dreemurr < - > Chara Dreemurr
7 Human Souls < - > 7 Monster Souls
Our protagonist wants to know the truth about the monsters and their fear of humans, but this time he will not do it alone, 6 special young monsters will accompany Jadsen and together they will find a way to break the barrier so that the monsters and humans can live. in harmony.

Protagonists:
Jadsen - A goat monster with huge DETERMINATION to free the monsters - Red Soul
Boogie - A ghost monster, being the younger brother of the Blook family, he is very shy, but has a great mind, being able to strategize during battle with a little PATIENCE - Cyan Soul.

Noel - A kyubi monster from Hotland and friend of Lidsey, she has great courage as a fighter and she's persuasive with others, she always finds a reason not to fight, with JUSTICE she will find the solution to problems - Yellow Soul.
Lidsey - A cat monster friend of Noel, she is a fan of the Mettaton show, among all of them she has the most magic, since she is a magician as a hobby, although she is happy with others, they do not think the same way, but they don't know She lets herself get carried away with the criticism of others, she has PERSEVERANCE to move forward - Purple Soul.
Lilith - A dragon monster being a recruit to the Royal Guard, she will chase us throughout Waterfall, before Boris and Noel are captured, they come to her senses and she decides to support them and have INTEGRITY with her choice - Blue Soul.
Jack - The Boss of Temmie Village, the most intelligent of his species, he always takes care of others like a good healer, he seems like a bitter monster, but there is always some KINDNESS in his heart - Green Soul

Legends from Below [My UNDERTALE AU] (Conceptual OST)

Name the fallen human
"FRISK".

Undertale was created by Toby Fox
In an alternate universe, 'Underswap' was created by Temmie Chang

Leitmotif:
- Ruins
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Yep, Frisk is still the first fallen human here! You play as Chara. On the other hand, "Determination" swaps with "Hope". Which means, "Hope" is the core trait of every human being. Chara benefits a lot of hope and possesses the soul of "Courage".

☂ An Empty Stream of Progress ☂

*Long since, two races reigned over the EARTH: HUMANS and MONSTERS.

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Leitmotif:
- Ruins(/Battle Against a True Hero)
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Since it's related to the intro, the barrier swaps with the gate entrance from the Ruins, and Mt. Ebott swaps with Mt. Emmett (which is actually real mountain if you search it up =P)Like Toby's old plan, Chara's going to seek for a refugee from a heavy rain outside, which explains why it'll be raining in the sanctuary. Chara will be donning a cute green raincoat and bring an umbrella as a... weapon.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Third update! Remember the very first version of "Left in Ruins"? Yeah, this is a combination of the two which additionally uses genesis soundfont to stay consistent with the technical SEGA and Nintendo swap.

* Ahuhuhuhu...
* What do we have here?
* You're lucky I was here to save you from that yucky flower, you know~
* After all, I do believe those pellets would ruin your texture.
* ...Oh, pardon me. Where are my manners?
* I am Muffet... the one who watches over the halls of Iciclus.
* It gets quite lonely down here, so I'm just ticked to have a visitor~

Fanontale is an AU that takes inspiration from Undertale fanon perceptions by using it to influence the roles the beloved characters take, as well as manifesting in-universe, affecting the characters and their stories.
This is not an Undertale AU about "What if Undertale fanon was good", but rather one that seeks to answer the question of "what if fanon perceptions had direct consequences for the lives these characters live?"

This plays when Chara first falls down into the underground.

Fanfare

This is a "role-swap" AU of UNDERTALE. It is partially meant as a homage to old AUs.

Notes:

- Fan songs/covers are perfectly fine.

- Some songs are outright "replacements" that play in the same context. Other songs take up the same soundtrack slot as an Undertale song but play in a different context. Mostly everything will stay in the same order as it is in the Undertale soundtrack, aside from some "extras". (Sorry for being so meticulous about this I'm autistic lmao)

- Everything (excluding otherwise credited songs) by @emi_head
