The battle sprite isn't finished yet

Underfell Toriel

Toriel: Prisoner of the Ruins Once a powerful queen her husband started taking his frustrations out on her with verbal and sometimes physical abuse. She learned to stay mostly quiet until her beloved child Chara was killed by her husband She lashes out and got a good portion of her face burnt She was banished to the Ruins where she slowly went insane. She became detached from reality Refusing to believe anything has changed. She made herself her own fake family out of training dummies from the Ruins They don't talk so she talks for them. Any human she falls she thinks is Chara.....and when they leave she relives that moment when she lost her family and shuts herself away for a week, not eating or sleeping before returning back to her delusional self again. She is dangerously over protective, killing any monster who talks to you when she's around. She has severe abandonment issues. Staying with you most of the Ruins When you try to leave she decides to destroy the Ruins exit once and for all but after being forced to fight you she plans to destroy the entire Ruins Because if she can't have you....no one can. Asgore can't get your soul if she does right?Ultimately she lets you go. Before going back to her stuffed family.... baking pies with the dust of monsters....

What is Twinfell? Twinfell is an AU based around Underfell (creator @underfell) where the monsters in the underground are very edgy, hateful, and fueled with fear. At first, the monsters were just like the ones in Undertale, but after they were trapped underground, they turned to hate and fear. Asgore was the first person in this AU to fall, and everyone went down the same path as him eventually.

The story of Underfell starts after the monsters have fully integrated into this mindset, but unlike normal Underfell, Twinfell also combines the events of Flowerfell as part of the AU. Flowerfell was created by @Siviosanei, where every time Frisk dies, the timeline resets. And when they return to life, a buttercup grows on their body. The flowers could not be removed as it hurts Frisk. Despite the cruel nature of the characters in Underfell, Frisk remains pacifist.

Twinfell takes place 7 years after Flowerfell happens. (In my AU version of Flowerfell, instead of the ending where Sans uses Frisks' SOUL along with the other 6 human SOULs to break the barrier and free all of the Monsters), he instead chooses to absorb Frisks' SOUL and lets the other 6 fade into nothingness due to his depression and grief over losing Frisk, as well as his fears that even after everything Frisk did trying to teach the Underfell Monsters the meaning of kindness and pacifism, that they might not have learned anything at all. Basically instead choosing to trap the UF monsters behind the Barrier with no way to escape.

Undyne, and Papyrus however, learning about Sans GODsoul and remembering how kind Frisk was, and seeing perhaps Asgore was wrong about all humans being heartless bastards, the 3 of them decide to make a rebellion group called the "Freedom Fighters" where they vow to take down Asgore, the Royal Guards as well as Asgore's "Kill or Be Killed" mindset once and for all and make the underground a much more inhabitable place.

How did the AU initially come about ? 

I was fascinated with the story and lore (as well as the overall aesthetic of Underfell) and obsessing over Flowerfell at the time, and I never noticed those two were completely different AUs until I basically did a deep dive into them both. And basically I wondered "what if I combined the two AUs together???" Another reason for it, was because I frankly got tired of the fandom for the most part sort of 'meme-ing' on the Underfell AU and other adjacent "Fell" AUs, I wanted to take the concept of Underfell and make it even more darker and twisted. And also dive even deeper into the whole concept of the Monsters losing their morality and humanity (which was the number one reason why I personally love the Underfell universe the most of all Undertale AUs I've read about and gotten interested in.) And wanted to do my own take on the verse, hence "Twinfell."

What is fighting like in the game ?

If there ever WAS a game made properly for Twinfell, I was sort of thinking the fighting system would be "real-time" instead of taking turns. (Or maybe its still turn based just like canon UNDERTALE, if you are fighting against any of the members of the Freedom Fighters group) vs the monsters on Asgore's side and The Royal Guard, who fight you based on real time.

In the RUINs, it's also turn-based, since technically the monsters are unaffiliated with either side, (some may fight you based on real-time depending how desperate they get in the fight. like during low HP moments etc.)

So I’m thinking just like in the canon Underfell Universe, that there isn’t a “pacifist” or a “ genocide” route.

More of like a Trust, Betrayal, Closure routes.

Trust: Otaku manages to befriend all the monsters and make them trust one another again.

Betrayal: Flowey or Akumu pins the monsters against each other resulting in Frisk getting blamed for it.

Closure: Otaku befriends all the monsters and manages to make them realize the wrongs they’ve committed. Finally finding closure within each other.”

((Still a WIP trying to figure out how this works))

What is the FIGHT/ACT/ITEM/MERCY interface like ? “FIGHT-ACT-ITEMS-MERCY" it’d still be the same as canon Undertale.

FIGHT- Butt heads against the monsters, but when things start getting seriously bad for the monster With them being at the last strand of HP they have, Flowey would step in and say “Maybe now they’ll listen to you” The fight option would be gone and then Mercy-> Spare HOWEVER if you ONLY fight them, it doesn’t mean they trust you, it just means they fear you. Choosing to only fight would still decide the routes.

ACT- same concept, trying to convince them not to kill you by making them trust you. Act takes longer per usual, but instead of Spare it’d be Mercy-> Convince Because by this time they have a little trust in you, and would come around wanting to help you. And themselves.

ITEMS- same thing, except you have a surprise box cutter in flowey's pot that isn’t known about until the end of the route.

MERCY - Self-Explanatory. May change to "Convince" or "Spare" depending on actions.

((Once again, might change later on. Entire AU is still a WIP))

TWINFELL Plotline:

((WIP Still Under Construction))

ALL ABOUT THE CHARACTERS:

AKUMU RENGAI

Both were abandoned on the side of the road near an abandoned shopping mall by their parents at the age 7 and for 5 years they basically lived on their own and did what they could to survive up until CPS (Child Protective Services) of Ebott City finally found and rescued them and brought to an orphanage where the twins lived in for 2 more years and would move from foster family to foster family without much success.

(Mostly due to the Fosters wishing to seperate the twins since Akumu was very rebellious, and was suffering from abandonment issues and trauma, while Otaku was very easy going and well behaved. They thought Aku was a problem child.)

To avoid getting seperated again, Akumu took and lied to her brother to go sight seeing by climbing Mt. Ebott for a "Family Photo" of the two of them standing on the mountain overseeing Ebott City, when they both tripped and accidentally fell into a massive hole near the summit and landed on Golden Flowers….

Fun facts:

The Eldest Twin (by like, 10 minutes)

Has the SOUL of Discipline. (A combination of DETERMINATION and BRAVERY)

Effects: The SOUL becomes rock-hard. Able to bounce off attacks without taking too much damage. (About half the damage.) Though if done, the attacks will eventually fall back down at a faster pace and change color to injure the host at double the attack power it would have normally been.

14 years old.

Very rebellious, and acts much older than her actual age.

Is also extremely protective of her brother, and will even kill both monsters AND other humans if it meant keeping him safe.

Practically trusts no one, except for Otaku considering he is the only family she has left that still gives a shit about her and puts up with her "bad attitude" and issues.

Able to see and use the SAVE stars, cannot RESET.

OTAKU RENGAI

Both were abandoned on the side of the road near an abandoned shopping mall by their parents at the age 7 and for 5 years they basically lived on their own and did what they could to survive up until CPS (Child Protective Services) of Ebott City finally found and rescued them and brought to an orphanage where the twins lived in for 2 more years and would move from foster family to foster family without much success.

(Mostly due to the Fosters wishing to seperate the twins since Akumu was very rebellious, and was suffering from abandonment issues and trauma, while Otaku was very easy going and well behaved. They thought Aku was a problem child.)

To avoid getting seperated again, Akumu took and lied to her brother to go sight seeing by climbing Mt. Ebott for a "Family Photo" of the two of them standing on the mountain overseeing Ebott City, when they both tripped and accidentally fell into a massive hole near the summit and landed on Golden Flowers….

Fun facts:

14 years old (younger than Akumu by about 10 minutes)

Unlike his sister, he's very kind, and able to pretty much adapt to any situation.

Is also very smart and interested in robotics and engineering from a young age.

Tries to stay positive, whereas his sister is a pessimist about most things.

Has the SOUL of DILIGENCE. (A mix of DETERMINATION, INTEGRITY and PATIENCE)

Effects: Otaku's SOUL creates a shield around itself that can withstand 2 bullet hits before it breaks, in which then the user will take twice the amount of damage when hit. The user with this SOUL must thus be more studious in memorizing the attack patterns and be more careful dodging.

Able to RESET, but cannot SAVE.

FLOWEY

Regained some of his emotions during his journey with Frisk

The boot he resides in belongs to Otaku

Uses his 'friendliness pellets' to heal the twins. Each pellet is worth 1HP everytime the twins touches one, they regain 1HP

TORIEL

Makes meat pies out of the fallen humans that had fallen into the RUINS, and stores their corpses in her freezer.

After Chara and Asriel died, Toriel become emotionally detached from everyone, especially her ex-husband

SANS

Let's Frisk take over 90% of the time

he doesn’t get flustered and isn’t always angry, he’s just very tired

let him rest

he sweats easily under that big ass jacket 

he’s been holding in a lot of emotional shit, so he’s constantly radiating his powers which mostly affects his jacket fur

is technically the most powerful with the consequence of hurting himself the most (Due to KR attacking him too since he ALSO has LV, and EXP)

Loves mustard and basically puts it on everything even when everyone else thinks it's disgusting or on food that probably shouldn't have mustard on it.

he tried on Papyrus’ boots once and felt alive

Sans says “I’M GOING TO HAVE ONE HELL OF A TIME”

Finished the cover art I made for my Underfell AU TWINFELL I made a remade of from this from way back in 2020

aaand yeah hope you all like

For full Res

What if thingy of Asgore vs Sans

based on an audio thingy my boyfriend TheOnePhun211/@theonephun211 made while voicing Underfell/Twinfell Asgore and it ended up inspiring me to make this

(also thanks to him for allowing me to be lazy and not do backgrounds lol) Asgore and Sansy drawn by me

but ye- also in case its not obvious, the Lieutenant Asgore is talking about here is about Papyrus cuz after Frisk died/failed to save the monsters from the barrier (and sans accidentally absorbed her SOUL) Papyrus convinced Asgore to spare sans and ended up taking sans punishment for him (hence how he got the 3 scars over his eyesocket) aaaaaaaaand ye- now Asgore's had enough of Sans shit that not even Sans brother can save him this time.
