Long time ago, two races ruled over
Earth : Humans and Monsters
One day, war broke out between the two races.
After a long battle,
the Humans murdered KING ASGORE.
The Monsters moved back

Petalegend talks about, what would happen if King Asgore died in the war. Toriel, the QUEEN and Asgore's wife, takes the throne for years. After those years, a new human, Frisk falls down to the underground. Fully blind, and doesn't knows how the underground changed without Asgore.

This Once Upon a Time is shared between the first four variantion.

[This AU is really inspired of the famous AU called "Aftergore"!]

[Petalegend] What Happened Once

*NO! DON'T TOUCH THAT ONE!
*Idiot! Fool! Nincompoop!
*Do you just waltz into other people's homes and touch things that aren't yours!?
*APPARENTLY SO!

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.

Not many people were really looking after Napstablook anyway, but those that knew them will tell you that they haven't seen them around in a few years. However, their good friend the Mad Dummy stepped up to take care of the family ranch in their absence. It's not a great life, but it's their life.

[Aftergore II] Songs of Ghosts

*Tch, I've watched your little adventure.
*You may have triumphed over adversity...
*You may have taken the high road sometimes...
*But that's just because you've been taking the easy street!
*So this is it! No more high roads OR easy streets!
*I've blocked off these streets with road blockers!
*And those road blockers say NGGGAHHHHHHH!

Talebreak is just another Slick Silver roleshift AU, nothin' to see here lol.

Undyne takes the role of Papyrus. She's not as successful here and is not the captain of any sort of Royal Guard. She's just a determined hero-in-training, working under her mentor.

[Talebreak] Maelstrom

This is a replacement to "Danger Mystery".

Asgore:
* If it's alright to you, would you mind looking after the small human for me, Alphys?

Alphys:
* O-oh of course!
* I'll do anything I can to keep the human safe from any sort of danger!
* Although there's one problem that I unfortunately can't get rid of...
* He's an advanced human-killing machine.
* The king's um... ghastly gladiator.
* He becomes dangerously relentless whenever he spots a human on sight!
* And there seems to be nothing that can stop him until he finishes the job.

Asgore:
* Ah... this is...
* Extremely worrying, perhaps I could-

Alphys:
* B-b-but don't worry!
* I promise you, I'll try my best to tackle this tricky situation.
* The human is going to be totally safe by my side!
* (Hopefully...)
+-+-+-+-+-+-+-AU INFORMATION+-+-+-+-+-+-+-
ALTERSAGA is a new roleswap AU heavily inspired by "Altertale" pair-swaps aspect: Toriel, Asgore, & Asriel swapping with Sans, Papyrus, & Gaster. However, in ALTERSAGA, there is more than just the abovementioned pair-swap. We will talk about this later, but for now...

Mettaton fills the role of Undyne. He is Alphys' greatest invention. As he achieves his lifelong dream of becoming a superstar that everybody craves, when Kris advances to Volcan, the Waterfall replacement for this AU, he puts on some "noble" act as a gladiator whose job is to knock his audiences dead with his royal, violent drama episodes of his dazzling extravaganza: "A Killer Robot Fabulously Chasing Down a Real Human Invader". His choice of weapon is- Okay it's unequivocally variated from a chainsaw, bomb, and even a blaster.

Hydromix is a roleshift AU revolving around Waterfall characters. Undyne takes the role of Sans. She's much older now, a veteran hero who now just spends her days enjoying retirement and wishing everyone stopped treating her like a frail old thing.

[Hydromix] Ngah, and All That.

[UndertaleAU - Smorgasbord] Chaos Report

Have to read the sheets. Have to rest for a whole day.
Delay through switching.

Not exactly an alternate universe. It's moreso merely a motif-swap project that can replace the original song files.
