Moonstertale 2: Duality of Revolution

We're back! Sorry for the long delay, we'll try not to let it drag on this long going forward. We have other tracks ready, just need thumbnails done for them.
Anyways here's an AU that doesn't get talked about much, Underpage! While it never got "rebooted," it did exist in two separate years, having one burst of tracks around this time in 2017 (wow, 4 years ago, time flies), and once again in late 2018. It's nice when AUs have their resurgence like that, even if it's only short lived.
We haven't heard from Limesar (the AU's creator) in over a year, but we hope they're doing alright.

For context on the song and thumbnail, Toriel takes the role of Flowey/Asriel, and Mettaton takes the role of Asgore.

"Mmm roasted MTT heart~"

Operation F.I.G. (short for Filling In the Gaps) is a project run by @slick_silver that aims to show some love to AUs that have either died or have been dormant for a long stretch of time by making music that never got to be made for said projects before. Many of these will in one way or another be speculative, and all tracks on this page are non-canon / unofficial unless the AU creator decides otherwise. If you are the creator of the AU and would like this track taken down for any reason, let us know and we will comply. Our main rule is that we can't do tracks for old projects run by members on the team, so this is all out of appreciation for others. If you're a musician (or artist) who would like to apply to be a part of our team, shoot Slick a message on Discord at Slick Silver#8818 .
Have a wonderful day!

[Underpage] What A Miserable Creature...

*In your wake, I have become stronger... powerful... invincible!
*I will be able to fulfill monsterkind's absolute revenge!
*I will finally be the one to lead the war!
*So, human.
*Why don't we have a little dance to celebrate my victory?
*...No?
*Such foolish, foolish human.
*Don't you think it's a little rude?

Ragel swaps with Flowey. Despite Rex inhabiting the mushroom, someone else is present... I wonder who could that be?

Toriel swaps with Asgore, definitively. She's generally known as the "Queen of Water" and brandishes an angel sword. Her palace's located in a hydrous 'Seven Seas' with a sepia aesthetic instead of grey.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
I thought it'd be nice to have an exclusive game over variation for Toriel.
