This idea was conceived back in early 2019, during that period of time where it was popular to just have "Megalovania" in your AU because UT:HH did it. I'd say it serves a purpose here, as it's an homage to Toadie's famous project "Sans Undertale: Barricaded." In their final battle, they embody Sans one last time.

No Survivors, and all that good stuff.
-Slick

Megalovania..?

THE GREAT AND MIGHTY PAPYRUS NEVER GIVES UP!
I WILL AVENGE ALL THOSE WHO HAVE FALLEN BEFORE ME!
UNDYNE...MY TRUE CHANCE TO PROVE MY WORTH HAS FINALLY ARRIVED.
AND WITH THE WHOLE WORLD AS MY WITNESS...
I WILL MAKE YOU PROUD!

Non-Aftergore BtERtD 5/5 of the Undying April event!

Hopeless is a roleshift AU inspired by the harsh aesthetic of Underfell. The harshness of the character's personalities altered the events following the human-monster conflict, leading to an underground riddled with disarray. That said, at their core everyone is still the classic characters you know and love, even if it's a little harder to see that than usual.

Papyrus takes the Undyne role, leading the Royal Guard in his mentor's absence. Always looking up to her, he models his leadership skills after her, and as a result has to put on a harsh persona.

[Hopeless] One Last Chance

✉︎ AH. A HUMAN.
✉︎ COME TO MEDDLE WITH OUR WORLD?
✉︎ AS YOU WISH.
✉︎ BUT IF YOU VALUE YOUR LIFE...
✉︎ DO NOT CROSS ME. AND ALSO...
✉︎ KEEP YOUR GRUBBY HUMAN PHALANGES OFF OF MY THINGS.

Aftergore is a series of AUs taking place after Undertale's neutral endings, in which a new human enters in Frisk's wake.
Aftergore VII, the Dog ending, details a strange ending in which Toriel, Papyrus, Undyne, Mettaton, and Asgore were killed, but everyone else was left alone. Now a little white dog rules the Underground by doing little more than sleeping on the throne all day. Somehow, this is working out...really, really well for everyone? NOTHING IS OUT OF PLACE. DON'T WORRY ABOUT IT. EVERYTHING IS FINE. =)

Gaster shares the role of Sans with Alphys. The strange anomalies that brought this timeline into being have summoned him from beyond, and he is rather cross with the fact that no one seems bothered by what happened other than him. The rest of the Underground may be under some sort of spell of contentment over the deaths of some of their great leaders, but you can't pull the metaphorical wool over this doctor's eyes. He's onto you. He always is. He's always listening.

* Oh! You've fallen down, haven't you...
* Are you okay? 

* Aw, c'mon, Azzy.
* Have a bit more faith in your ol' pal Flowey...

* You met them?
* Today's just full of surprises...
* Well, I trust you're in good condition, then.
* ..I should probably introduce myself.
* Howdy! I'm ASRIEL DREEMURR, Prince of the Underground!
* Have a warm welcome to the Sunken Temple, and enjoy your stay.

Since we're in early-game territory for MT 1, why not delve a bit into MT 2 material for a bit, huh?

Mortatoriel 2, the "Betrayed Underground" ending, details an outcome in which a once-merciful fallen human suddenly kills many monsters in Cool Cool Peaks, including Grillby and Dappertune, and Queen Toriel. Former king of monsters, Asgore, has returned to reclaim the throne, trying to amend for his mistakes and reassure his people that everything will improve despite their suffering. Royal scientist Undyne has tightened security in the Underground, and monsterkind refuse to trust humans anymore. Even if humans did show some kindness in the past, anything can happen.

Asriel takes both his and Toriel's role. After his father returned to the throne, Asriel became more aware of his connection to the crown and is taking on heavy responsibilities of being the underground's prince, especially in light of the Cool, Cool Peaks massacre. Knowing well that Chara once had the promise of pacifistic humans, he secretly wanders into the Sunken Temple to watch for fallen humans so that he can guide them towards a path of kindness and compassion.
Note 1 (05/08/21): @the_freaking_weirdo has updated the thumbnail for this track with a slight tweak to Asriel's sprite; more specifically, some things hanging from Asriel's cape that were not visible (due to blending into the background with a black color) are now visible, with a dark blue color matching his cape.

Note 2 (07/04/21): Track thumbnail has been updated again by @the_freaking_weirdo.

[Mortatoriel 2] The Prince

*(Another "beautiful day.")
*(If only it felt as beautiful as it looks.)
--

In Deltarune: Switching Suits, Kris and Susie technically keep their roles, in that Kris is the protagonist and Susie is the deuteragonist. However, they swap lives. Susie is the adopted daughter of the Dreemurrs who is known and loved by her classmates, while Kris is the widely feared school outcast. Kris doesn't get a fun ride to school with a parent, they just have to walk there alone.

The Start

*CONGRATULATIONS, DARLING!
*YOU'VE WON THE OPPORTUNITY TO TAKE A PEEK BEHIND THE CURTAIN!
*THIS IS WHERE THE MAGIC HAPPENS.
*I'VE FLIPPED THIS CREEPY OLD HOUSE...
*AND MADE IT THE CREATIVE STUDIO FOR MY NEW PRODUCTIONS!
*ISN'T IT JUST FABULOUS?

Aftergore is a series of AUs taking place after Undertale's neutral endings, in which a new human enters in Frisk's wake.
Aftergore IV, the Queen Undyne ending, details an ending in which Toriel and the Ruins monsters are killed, but everyone else is left unharmed (other than Asgore of course). Undyne rules the Underground with an iron fist. Humans are to be treated as enemies, not friends.

Mettaton takes the role of Toriel. Deemed to not be taking the fate of monsterkind seriously, Undyne banished him to the desolate Ruins. But when life gives Mettaton lemons, he makes glamorous MTT-brand pink lemonade! He's turned the Ruins into the site of all of his new televised escapades; he's essentially made himself the star of a much smaller production. Sure, it's grossly insensitive for him to do such things at the site of a massacre at the hands of the previous human, but sensitivity shmensitivity, right?

[Aftergore IV] Backstage

* ... Now darling, I want you to please take what I'm about to say at face value.
* There's no cameras. No audience other than our mutual friend, and they're moral support.
METTATON... EVEN AFTER BEFORE, I KNOW I CAN TRUST YOU. PLEASE GO ON.
* Alright... It's just...
* You're really great, okay?
WELL, I MEAN... I AM THE GREAT PAPYRUS, AFTER ALL...
* No, seriously.
* Your self-confidence is inspiring!
* You're able to trust in yourself, you don't need others to validate you.
* Y-you... 
* There've been times where I've not truly trusted in myself.
* Where I've felt like a fraud. A Ghost, not the man I really am.
* And knowing you're on my side has really helped, okay?
WELL!! I'M TRULY GLAD I COULD HELP YOU, EVEN THOUGH I DIDN'T QUITE KNOW I WAS-
* A-and you're so kind! You're proving it right now, darling.
* You've made the Guard do the right thing. You've got them gardening for Christ's sake!
YOU CAN'T SPELL GARDEN WITHOUT GUARD!! OR 4 LETTERS OUT OF IT ANYWAYS.
* Honestly you're the kindest person down here, except for maybe the human and even then it's debatable...
* Even when you try and capture someone, you're so polite about it...
* I wish I could be like that, rather than the way I have been...
NOBODY HOLDS IT AGAINST YOU.
* Well... I do.
* ...
* Look. Papyrus.
* You... You make me feel like Mettaton.
* Not like who I was, before any of this... But who I am.
I... OH.
* And you've given me all the confidence I need to keep going, darling.
* And I love you for it.
* And I don't mean that hyperbolically, or platonically.
I... I DON'T KNOW WHAT TO SAY...
* You don't have to... Reciprocate, you know. I just needed you to know that.
I JUST NEED TO... TO THINK.

Furtherfell is an AU, split into several branches, portraying the various hypothetical neutral endings of the 'canon' Underfell. In this instance, 'canon' refers to the version on Tumblr, created by the infinitely talented Fella. They don't actually consider it canon, but for Furtherfell it most certainly is. It can be found here (https://underfell.tumblr.com/)
It is inspired by the concept of Aftergore, though only in concept and not in execution. Our story follows a human by the name of Hare, entering a world they do not understand, that has been forever changed by the actions of someone they've never even met.
We won't be 100% accurate to Underfell; some elements may be changed, either due to a lack of information or just due to us wanting something to differ.

"Furtherfell - Rethroned" follows on from an incomplete pacifist ending. Toriel comes out of hiding, and establishes herself as “Mother” of the underground, making swift changes to how things work. She maintains a strict rule, attempting to prevent another reign of tyranny. Humans are to be treated with kindness, and to be delivered to the Queen.

In this branch, and potentially other branches (wait and see bitches), Papyton has been made canon. Fella likes it, so we decided that on the Anniversary of the AU we're based on, we'd give them some well-earned fan-service. 
Papyrus' higher position in the Guard led to him getting to meet the Royal Scientist, and therefore also their cousin. Meeting his idol was a dream come true, so he ended up gushing about how much Mettaton's show means to him, whilst also trying to make himself seem great and terrifying. Mettaton had seen it all before, and honestly wasn't impressed. 
It's been 6 years since then, though. Now Mettaton's the one gushing about Papyrus. And how will Papyrus respond?
Well, the next track should tell you more than enough about that.

FwugRadiation - SWAPPED RHYTHMS Soundtrack - ?? SONG OF THE SKELETON'S UTTER GREATNESS

Zillaswap is an Underswap take by @the-bowz-16716601, one that we took interest in because his interpretation seems really unique - like, just look at that Papyrus design. Look at that lad. Don't you love 'em? Papyrus looks the way he does 'cause after a falling out he had with Sans, he had a bit of an accident. Y'know. Just a lil' bit. If not for the steampunk scientist Undyne's repair work he probably (or, y'know, definitely) would've died.

Delay through switching.

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