Underfell - Blog Posts

mah baby! just new icon

Underfell Sans just killed some random poor soul. It started as a warm up sketch. I’m going to draw some more undertale (or underfell) pretty soon.

Ok, It’s 1:55 and I am having my exams tomorrow. I can’t sleep, can’t eat and I probably should repeat something before tomorrow, but you know what? I can’t! Every time I tried to I’m having a panic attack! So I decided to draw something to distract myself. And the first thing that popped in my mind was @spacegate fanfic trust (because it is awesome and I just read the 6 chapter).The second thing was my love to mixing different au. So I drew the idea that was floating in my head since christmas: her classic sans and pap, underfell au sans and pap with mix with her au and underswap version. In underfell I think sans and Pap will always use half-transformed form for protection. And because in underswap muffet and grillby switching places I just put muffet there. Also both Pappys are older in my headcanons for aus, so deal with it. Why is kids wearing sock in waterfall? Because i didn't planned theь being at the waterfall! And muffet is wearing this ugly dress just because! But when it came for coloring i was so tired and to be honest - i just wanted the whole thing to be over already so i got really really lazy. And I know that this pic is looks like shit but i wasted too much time on it to not to upload. PS:[ @spacegate​ , you were the person who got me into this au with your amazing fanfic. Thank you.]

Three more sketches, because it’s all I'm capable of for now, since i'm having my exam tomorrow. I promise, when this whole exam thing will be over you'll get something digital from me. 1 and 2 are pieces of the one idea where underfell!sans and Underswap!Sans changing their timelines by accident (and they don’t realize it until they talk to the local Pap) 1)Underswap!Sans and Underfell!Papyrus (poor, poor Sans...) 2)Underfell!Sans asn Underswap!Papyrus (Papyrus is probably asking something like: “Are you feeling ok, bro?” and Sans is like: “ For fuck's sake! I already told you I will collaborate traps later!... The fuck are you wearing?” *probably doesn't realise that he is in different timeline*) 3) This is my headcanon for underfell. It’s 6 years old sans and Papyrus is 16. So in my headcanon Pap is the older one, and he is the one who took care of himself and Sans, when their mother died while giving birth to Sans. And their father abandoned them a long time ago. It was really hard to Pap, he was forced to kill for surviving. And he had learned one thing - there is no place for weakness in underfell. It’s kill or be killed. In main time he and his lil bro just trying to survive, by searching for food and fighting with other monsters that attacking them.Pap is only started to teach Sans the basics of bone magic and he is really harsh with him (because he can't let his bro to die because of weakness). I’m planing to draw a comics of this one (and I guarantee that it will be a digital)

And this is it, guys! This is the moment of my life when I have absolutely no clue about wtf am I doing. And to celebrate it here: have a quick underfell!Sans sketch that I did on my math class. Maybe I will digitalize (is that’s how you spell it?) it later. The main problem I’m having with digitalizing(?) something is that I don’t fucking now how to do that. I mean I have everything you need for it (like tablet) and still… So feel free to send me any tutorials you’d like. I’ll appreciate that very much.

sighhh, does anyone have canon underfell things, mostly lore/larger designs i can look to? doin' a rp and realized i needed to know much more than i do, and i don't trust fandom wiki :sob:

so today i put as many sanses on a wheel as i could remember, and spun it to make 'shipchildren' of the two i got. not actually personally shipping them lol, did this purely for designs to start, we have Macchi, or Ink x Ccino

T0n1c (tonic), Reaper x Fresh

Cerise, Dust x Lust

and finally Pulsar, Outer x Fell

Underfell comic that our friend requested <3

Underfell: Misery and Sorrow

Im deciding to call my Underfell take "Underfell: Misery and Sorrow"

These are sketches of concepts for the Ruins replacement the Catacombs specifically some of the battles and dialogue and such

Underfell...it's been a while

Dree this a while ago and realized I forgot to post this

I want to revisit my Underfell take so here's Undyne and M.K.

Undyne:

Armor made to resemble a samurais

Doesn't remove her helmet until collapsing in Hellcity (Hell-Land's new name)

She doesn't cover her missing eye or any of her other scars or let them heal because she views them as badges of honor

Likes Heavy Metal and watching anime

Her scars are from intense training sessions with Papyrus

Doesn't trust humans

Obsessed with being strongest and finding a worthy challenge as even Papyrus doesn't provide enough challenge for her anymore

Respects the human after they beat her because she finally found someone new to train with

More Stern and cruel

In the genocide route she doesn't save M.K. and in her rage she becomes Ever Dying but this form slowly kills her

Already dating Alphys and waiting to propose

M.K.:

Member of a small gang of rebels in Freezeout (Coldtown's new name)

M.K., Snowdrake, and Jerry act as new mini bosses in Freezeout

In the fight M.K. can only use one attack where they swing their sleeves at you

They encounter you in Dark Swamp (Darm Sea's new name) and act as an annoying shit

They try to get you caught by Undyne so that while she's distracted they can try to battle her

Undyne eventually catches them and sends them home

Mocks the Royal Gaurd by impersonating them in ways that quote their Undertale counterparts

They steal your umbrella >:(

Gif of them all to see them better

Spooktober Day 31

Noooooooo

I missed it

I missed the deadline

I took too long typing this i realized halfway through that it was already November

Please accept my late Halloween Art 😔

Anyway today was a your choice one and I'm actually gonna start with Jared's:

He drew a bunch of different horror monsters he's created

Evil Spacecat is from a parody of Killer Clowns from Outerspace, Rosie is a possessed doll, Elf is an evil elf, Brayden Hook is a slasher from the countryside, Max Denvor is a sunken Diver killer, Gator is a gatorman killer, Snake Eye is a snake demon, Bishop is an evil priest based on the Nun, and Zoid and Pete Grisly are new to me

I did a handful hence why it's late

All from my different aus (or rather takes on AUS): Underfell, Deltarune Chapter Rewritten, and Underswap)

If you wanna learn more about CR and Underswap check out my swap au blog @deltaswap2442 where I do swap au. Been kinda inactive on there for a bit because of this but I plan to make a return

Happy Late Halloween

Underfell Routes (My take)

Neutral-Selfish Route

The neutral route has the most ending so each one is very different but the basic cost is Frisk selfishly only saves themselves and escapes the Underground (some routes along with Flowey).

The basic timeline is:

1. Teaming up with Flowey

2. Leaving or killing Toriel

3. Befriending, defeating, or killing Papyrus

4. Escaping or killing Undyne

5. Saving or Killing Mettaton

6. Killing Alphys

7. Fighting (if you have 1-5 LV) or being let go by Sans

8. Killing Asgore

9.Flowey absorbs the Human Souls to stop the protagonist from leaving everyone behind without trying to save them

10. Fighting and either saving or killing Savior Flowey

11. Chara confronts you trying to sway you to do the freedom route now

----------------------------------------------------------

Pacifist-Freedom Route

Convincing everyone to realize their flaws and work together for their freedom

1. Befriending Flowey

2. Convincing Toriel she needs to learn to move on and handle her grief properly

3. Convincing Papyrus to reconcile with his brother

4. Date/Hangout with Papyrus where you convince him that he doesn't need to be a royal Gaurd to have lots of friends

5. Saving Monster Kid and convincing them that they don't need to act tough and mean to get people to be friends with them

6. Saving Undyne from dehydration and showing her not all humans are evil

7. Hangout with Undyne where you convince her that her pursuit of being the strongest has pushed away those she's cared about

8. Saving Mettaton from Alphys and convincing him that he's beautiful on the inside

9. Convincing Alphys that she's not the bad person she claims to be

10. Date with Alphys where you convince her to do the right thing and come clear about her mistakes. Also where Undyne proposes to Alphys

11. Discovering the True Lab and saving all the Tortured Souls (Amalgamates) and convincing Alphys to let them go free

12. Fighting Sans and showing him all the good things youve done and that everyone deserves mercy

13. Fighting and sparing when he tires Asgore much to his surprise and he apologizes to everyone for all the awful things he's done in pursuit of freedom

14. Flowey absorbs the human and monster souls convinced that when you make it to the surface you'll just reset and take away everyone's happy ending and becoming Asriel again

15. Saving Asriel by first saving the souls within him and then telling him that you are in this together Asriel then breaks the barrier freeing everyone

16. Chara confronts you and tells you that you can move on now and let everyone have their happy ending and tries to convince you not to reset

----------------------------------------------------------

Merciless-Cruel Route

Killing every monster you fight. Taking away the monsters hopes

1. Befriending Flowey

2. Killing Toriel causing her to try and give up her soul to you but it's too weak

3. Killing Papyrus causing Sans to disappear for the rest of the game

4. Killing Undyne causing her to drop her ring she meant to give to Alphys

5. Killing Mettaton causing him to shut down all power in the Hell-Land and the Labyrinth

6. Killing Alphys causing her to attempt to blow up the Labyrinth in an attempt to take you down with her but Flowey helps you escape and now almost everyone in Hell-Land is dead

7. Sans lets you go like the coward he is to let you kill Asgore 8. Kill Asgore causing him to attempt to absorb the Human Souls but they all break

9. Flowey tries to stop you from leaving trying to question why you did all this

10. You kill Flowey by cutting off his stem and stomping on him

11. Chara confronts you and forces you to reset

----------------------------------------------------------

Genocide-Lost Control Route

Frisk fully gives up control to the player and kills all the monsters in the underground not just the ones the encounter but actively hunting down every monster possible

1. Befriending Flowey

2. Killing all the monsters in the Catacombs and Toriel causing her to realize that you aren't her lost child or even human

3. Killing everyone in Coldtown and Papyrus causing him to regret not trying to make things right with Sans and Undyne

4. Killing everyone in Dark Seas including Monster Kid and the Undyne who become Undyne the Ever Dying. After killing her she warns you that Alphys has a plan to make sure you're gone for good before dropping the ring for Alphys

5. Flowey betrays you and tells you that you've gone too far and that he can't sit back and let this go on (this might be moved to before Undyne's fight)

6. Killing everyone in Hell-Land and the Labyrinth along with Mettaton.NEO who shuts down Hell-Land and the Labyrinths power

7. Alphys injects herself with determination she extracted from the Tortured Souls and turns in Tortured Alphys in an attempt to finally stop you. She can't be killed and you have to wait until she melts to nothing from too much determination 8. Sans fights you to get revenge and after he tires out you're able to kill him

9. Asgore fights you like normal (unaware of your murders) and is killed

10. Flowey attempts to stop you now and force you to reset but he fails

11. Chara confronts you and tries to force you to reset

Undeefell Ruins Enemies

Mild trigger warning on Whimsum

Bullfroggit: Basically Froggit but meaner and more aggressive Blynde

(Loox): Lost his eye and is more mean but also more cowardly

Fell! Whimsum (No new name idea): Whimsum already had references to suicide. So Fell Whimsum has a noose around it's neck and begs you to kill it. It's meant to also demonstrate how the genocide route of Underfell being treated more like mercy route than the pacifist route

Fell Migosp: Is the opposite. Instead of aggressive when with friends and docile alone. It is docile when with friends due to being scared of them and aggressive when alone due to anger of you killing the other monsters or lashing out cause it's alone depending on your actions

Fell Vegetoid: Instead of wanting you to eat it, it wants to eat you!

Fell Moldsmol: Is acidic and that's about it. Just acidic slime

Fell Misgospel: Just a crazy jester who hates being around others but is happy though violent when alone

Fell Parsnik: Turned to Stone. The snakes control the body like a puppet.

Fell Moldsmol: Acidic and stores bones of other enemies within it. Juggles a skull that it sometimes uses in place of a head. Misgospels only friend

The evil Spongetale. Basically my Underfell+Spongetale

SpongeBob:BLEH HAH HAH HAH (MWAH HAH HAH!), Bubblebrutalization (Bonemassacre)

Patrick: patrick! (sans!), Song I Wrote Just For When You Have To Kill Me Uh Patrick (Song Made For Being Forced To Kill Sans), PLANKTOMANIAC (MEGALOMANIAC)

Underfell Sans+Papyrus

Forgot that I never posted them

I'll add their backstories later but RN I'm tired

She now also has a sprite

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....

Made them into sprites

Underfell Frisk, Flowey, Asriel, and Chara

The trauma children!

Trigger warning for suicide and abuse

Frisk is the human you play as. Quite simple. They bonked their head on a stick on the fall down luckily they're good with first aid. They're a friendly child despite all the shit they went through. Their birth parents were abusive and the trauma rendered them mute with minor PTSD. They were put in an orphanage but escaped and went to commit suicide by diving into Mount Ebott but by a miracle they survived and saw it as a sign from God that they have a mission and after meeting Flowey who presented himself as a fallen angel they set on a quest to heal the wounds of an underground torn apart by the death of a child and the failure of a king.

Long ago monsterkind was ruled by Asgore and Toriel and their son Asriel and later their adopted child Chara Chara was the adopted child of the Dreemurs their past is something they are holding me at knife point not to discuss so don't ask. They are Asriel's only real friend. Things were rough even with the Dreemurs Toriel and Asgore were always bickering and it usually ended with Toriel sleeping outside the castle. Asgore wasn't cold hearted but incredibly stressed because the underground was in great peril and everyone was turning for him for help. He still cared about his family but put his kingdom first. He loved Asriel dearly and tried to make Asriel a better king than he ever was but he never did care much for Chara He believed Chara was a bad omen. He didn't trust humans after they betrayed his kind so long ago and neither did the rest of monsterkind One day monsters stormed the capital demanding Asgore kill and harvest Chara's soulIn a moment of weakness....he killed his own child. Toriel lashed out at him and he in a fit of rage and confusion snapped off her horn and banished her. Asriel horrified by this took Chara's soul and ran away to the surface but was not welcomed by humans who killed him brutally That was day Asgore lost everything And it was all his fault. That was the moment that broke Asgore and would lead to the downfall of his kingdom. A while later the scientist Alphys, who began to slowly descend into madness after learning the truth of what happened to Gaster, Toriel, and Chara at the hands of Asgore, extracted determination from the souls of dead humans to imbue life onto a flower. Not just any flower. But the first flower to grow from pollen brought from the surface from Asriel And so Asriel was reborn as Flowey He only has one goal: escape. However he doesn't remember anything about how he died Just that he was once a prince. He accompanies you in every route of the game acting as a guide, mentor, and bodyguard In the genocide route he adopts the motto "Kill or be killed" and through the players bad influence becomes like the Flowey from Undertale In the neutral route he betrays you. Not Frisk He actually cares for Frisk But YOU the player. He knows that once you escape you'll just reset again. Take away your happy ending Take away his happy ending Take away everyone's happy ending So he turns into Omega Flowey (who resembles a biblically accurate Angel) to fight the player specifically and try and save everyone In a way he's the true hero of the game. In the pacifist route it's mostly the same except after seeing your friends he has hope that you won't reset, that you'll give everyone the happy ending he's been hoping for and he absorbs the souls and all of monsters to destroy the barrier and save everyone....until he becomes Asriel....He suddenly remembers the events of his death and realizes the underground isn't worth saving....No one isSo he sets out to put this world out of its misery. But through the power of friendship you convince him that there is still hope and that your dreams are able to come true and he destroys the barrier.....And everyone lived happily ever after......until you betray them all..... because well.....there's other endings to get....you just have to see every possibility......you're never content even with everyone happy.....and so you reset again. Just to see what would happen if you.....i don't know...Killed everyone? =)

Underfell take

My take on Underfell Papyrus. He's this over the top supervillain and co-captain of the Royal Guard. He's a bit of a kiss ass to the king and takes his job very seriously.

He has two separate outfits here one that he wears when harassing you through Snowdin that covers his mouth because he is embarrassed by his crooked messed up teeth

And his battle armor which is too heavy to move in properly so he only wears it during the final battle since he's just using bone magic on you

Side note I have no idea what I'm doing in math now

A Different Undertale

I have a new AU idea but this one is more story focused than art focused and also contains adult themes. So be warned!

This is basically a fusion between Underfell, Mafiatale, and Negatale with some minor inspirations from Lusttale and Horror/Axetale

In this universe the humans sealed the monsters underground but along with them, they sealed away their pain and suffering. So the humans have found nothing but peace and prosperity while the monsters have violence and suffering. And any human who falls underground will have their hope taken away.

When Chara fell while trying to meet the monsters the broke their arms and legs and were reduced to a wheelchair. Despite this Asgore (who resented humanity) was still suspicious of them so when Asriel accidentally poisoned himself (unrelated to Chara) he blamed Chara and killed them. Toriel was banished to the Ruins for helping humanity and has since developed memory loss. She doesn't remember who killed her children all she knows is it was someone she loved (so when she fights you she assumes that person was you meaning you can't run away). Asgore declared war on humanity and banned all human creations like anime, magicless weapons, and even homosexuality.

The underground is filled with despair, gangs, drugs, violence, and injustice. Only the kindness of one human, who fell and lost all their memories, can save them
