All of the intro sequences -- at least, as far as I've currently decided, this could easily change -- pretty much convey the same information that it does in Undertale. Humans and Monsters live together, war breaks out, the usual.

After unfortunate circumstances took her and her husband's lives, the royal scientists went to work on finding a way to bring her and her husband back. Using dead snails (note: not Monster snails, just boring old regular snails) and Determination, they had managed to bring Toriel back. Now she aimlessly roams the Underground, searching for something that might bring her back fully, as opposed to being trapped in the now undead body of a snail.

[T-SPIN Double] Watching Over You

* You wish to return "home", do you not?
* Ahead of us lies the barrier.
* The only thing keeping us safe here...
* And you seek to destroy it..?
* ... Or just to cross it?

* My child, don't you see...
* How much you'll hurt us..?
* In your single-minded quest to go "home", you are going to ruin everything we have.
* By shattering our safety, or our throne.

* I am only protecting you, do you understand?
* Protecting you from your naivety.
* Protecting you from yourself!
* Protecting you from... what I'll have to do!
* So, be a good child and stand down. 
* Please...
* Please.
* I BEG YOU

* ... But no.
* Oh, no no no, no no...

* You humans never see reason, do you?
* It doesn't matter how many monsters you must endanger for your own sake.
* My child, you are breaking my heart!
* You are just like the others, aren't you..?
* Just like the last.
* So willing to condemn us for your freedom!
* You truly must hate me..!

* ...
* You could have been so happy here with us.
* It could have been so easy.
* But for them... for the people I swore to protect...

* I shall set that hope aside.

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 Furtherfell: Rethroned, Toriel takes the role of her ex-husband, Asgore. Faced with a leaderless Underground after her ex-husband’s death, Toriel knew she was the only one that could do what needed to be done. The only one with leadership experience to make up for the King’s demise. The only one who could stand the weight of the entire Underground on her shoulders… She was almost right. Mother Toriel’s policies made the underground a better place for almost everyone. A new Captain, a new Scientist, all in the interest of improvement. However, the self-styled Mother has almost fallen apart. Beaten, but not yet broken, by the world she’s tried so hard to save, Toriel decrees that humans are to be treated with kindness, and brought to her.

However, when she's faced with a new human, this seems to change. Hare has resisted her Royal Guard at every turn, and so clearly does not merely want to have a slice of pie with her. Hare wants to proceed, no matter their reasoning for doing so. She cannot have someone threaten her protection, threaten to undo all of the progress that she has made. And so, she goes down in flames.

Welcome... to T-SPIN! A series of AUs based on Storyspin and its further-spun brethren. Follow our protagonist on the adventures they have through each AU's version of the Underground.

T-SPIN Double is based on Spinspin. You can check out the playlist (https://soundcloud.com/t-spins/sets/ts2-ost) or the T-SPIN channel in the Argenoverse Discord (https://discord.gg/qmtQxwYKfD) for the most up-to-date version of the rolelist including whatever minor roles have been decided on at that time.

Once I have a more expansive plot synopsis for these AUs individually I will put them here (and in future tracks' descriptions), but for now this will have to do.

Mettaton was once King of the Underground, ruling alongside their cousin who was officially moreso the royal advisor, but he treated them like royalty just as much as he treated himself as such. He let this power get to his head a bit and started doing things that mostly benefitted himself. Nothing that'd actually put monsters in direct harm, he wasn't that stupid, but nothing that actually did anything good for them either.

One fateful day, he was overthrown by the people, exiled to the shadier part of the Underground, and the royal advisor was crowned monarch in his place.

Now Mettaton lives in the so-called slums of the Underground. He's managed to find a fairly decent space to live in, a place where he can recharge if necessary (which is very frequently the case given how much power his body drains... if only he had a more energy efficient mode) and where he can lie on the ground feeling like garbage.

Of course, despite his exile, he puts on a smile and his signature flamboyant confidence and acts as though there's nothing wrong! Because why would there be?

Complete sidenote, whenever relevant, thumbnails will also feature character designs now! The old thumbnails will slowly be updated as well, but my priority for the time being is going to be the ones that are being actively uploaded.

Constantly acting as though everything is fine can be very draining, both emotionally and physically -- Mettaton is no exception to that. By the time Oliver shows up at his house, he doesn't really have the energy (literally) to keep it up anymore, being a bit more quiet before inevitably breaking down in front of Oliver.

As Oliver goes to bed to take a quick nap before they continue on their adventure, they can hear Mettaton quietly singing to himself, which slowly puts them to sleep.

[Doused Flames - Overworld (1/10)] Oh! Ruins...  [OST]

*(You don't know, but somehow it smells like insensitivity.)
*(Your sense of mild disgust urges you to stay determined.)
*(So that's exactly what you'll do.)

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] Tonally Inappropriate Glamour

T-SPIN is a set of Undertale AUs made by Toadie, based on Storyspin and its further-spun brethren, which probably have better names than "Spinspin" and "Triplespin" but none that I can particularly specifically remember.

Each of the three AUs have their own rolelists which can be found in their respective playlists.

You can also check out the Argenoverse server for more information about T-SPIN.
