Unexpected Guests Chapter Ten, Act Two: Page 23

First / Previous / Next (coming soon)

Alphys manages to ignore her girlfriend long enough to bring up a good point; as awesome as Undyne is, she's not invincible. But they aren't the only monsters still on the battlefield...

Look for the next update on Oct. 10th!

[catboymoments]

I watched a bit of an undertale playthru today and my autism IMMEDIATELY went into overdrive so I wrote/drew out my monster species headcanons :P I love them so much can u tell

[onyourowndaisymae]

obey me characters and incorrect things about the human world they believe in (headcanons)

just because they're old doesn't mean they're smart

somebody, at some point, convinced mammon the ninja turtles were real. if you ask him about it, he scoffs-- of course he doesn't think there are human-sized ninja turtles running new york city. they're in hiding so people won't find them and hunt them down, duh. he's so matter-of-fact about it that it makes you feel like a dumbass for a moment.

beel thinks everything that falls in the fruit and vegetable categories grows on trees. he cannot conceptualize another way they'd grow. what do you mean carrot trees don't exist...?

satan learned about subways in major cities and, coupled with his previous knowledge of historical railways, sort of just assumes that every country has an elaborate high-speed rail system. sigh. i wish you were right, satan.

lucifer thought that everyone carried a weapon on them in the human world. they don't? isn't it dangerous up there? why would you walk around unarmed, mc? what happens if somebody comes up and attacks you? somehow this misunderstanding has turned into a lecture for you--

asmo severely overestimated the human life span. his brain starts lagging when you tell him the average human lifespan in around 80 years. that's it? that's all? that's nothing! how do you even get anything done in that little time? he has demonus older than that sitting beside his bathtub! (asmo drinks in the bath, don't @ me) you would expect things to get a little angsty here as he realizes how short your own lifespan is, but for some reason he just assumes you're exempt from this rule. he'll make solomon figure out a way to keep you young and pretty with him, don't you worry!

levi didn't realize that the media in hell is different than in the human world. the thought of nobody on earth knowing who ruri-chan is ruins his evening. you broke him.

BOOM, Down Syndrome your Frisk

[atwas-meme-ing]

*slams hand on desk* I don't CARE if it's a non-canon fangame, UTY is still part of the family!

I'm choosing to believe that when they get to the surface, Martlet and Papyrus become friends and spend all their time together designing puzzles. Star and Undyne have literal fights- her with her Spears of Justice, him with his Sixgun of... well, of Justice, too, I guess- over "anime vs. westerns." Muffet and Mo start a cafe together. Mettaton asks Alphys to give a SOUL to Axis' fiancé (with Blooky standing conveniently nearby). The Feisty Five set up the Wild East in an IRL ghost town and Mew Mew becomes their dance hall queen, with Bailador and Shyren composing the music. Dalv starts writing children's books, and MK and Suzy are his biggest fans.

This is MY headcanon, YOU CAN'T STOP ME.

✨️My Undertale Headcanons✨️

When they came out of the underground, most/all of the characters live next to eachother like a neighborhood. Mettaton has a big mansion and it's a little far from the rest of them, but it's still close enough to be part of it. He helped to afford a new "Blook Acres" for his cousins, Dummy, Napstablook and Mad Mew Mew (Shyren and her sister live next to them). Sans and Papyrus made their home exactly how it was when they were in the underground. Toriel, Frisk, Asgore and Flowey's house are right next to theirs. Alphys and Undyne live together and it's right next to Sans and Papyrus' house. Muffet and the other spiders have a Bakery and Grillby has a bar/restaurant.

Some of the monsters stayed in the underground. It's very silent there now that almost everyone is gone, that's one of the reasons why some monsters stayed — because of the silence. It's a bit depressing sometimes thinking about how that place is now so empty when there were so much people and happiness everywhere. Now it's just the snow and empty houses in Snowdin, waterfalls and water drops in Waterfall, and the sound of lava and the core in Hotland. MTT's resort is also closed. Monster's history is still preserved there, so some humans go to the underground to learn about history.

Mettaton loves chick flicks and that's how his love for the humans started. He found some of them at the dump, they came from different decades and not all of his collection is about romance, he once found DVDs about talk shows and quiz shows, also black n white movies from the golden age of hollywood. He didn't know the name of most of the actors or where those movies came from, except that they came from the surface. He knew at that moment that he wanted to be like them. He also found some CD's and even not knowing them so well, he absolutely loves pop singers like Lady Gaga, Beyoncé. He just never had enough information to know about their other albums or their personal lives. That was too far from his reality. Now that all the monsters are outside, he really wants do befriend them and it's a big fan of Rupaul's Drag Race. He would love to be on that show. Mettaton now has a lot of human fans now too. He loves to post things on social media, having thousands of followers in each one of them. He also has two or more shows in a human TV channel, maybe even his own MTT channel.

Mad Mew Mew ABSOLUTELY LOVES Babymetal. The RAGE mixed to that japanese kind of cuteness. IT'S PERFECT!!! Her favorite song is Doki Doki Morning (She likes meowing during the "mew mew mew" part and when the metal finnaly strikes it's just RAGEEEEE but then the song is cute again and she's all "mew mew mew :33333"). She listens to Babymetal alongside Alphys and Frisk. Now she's an otaku too just because of Alphys. They are friends. Mew Mew still has a little crush on Undyne, but it's not like she wants to date her anymore.

Alphys dances to Babymetal alongside Frisk and Mew Mew. They live in good terms and Alphys let them have the doll because she's more happy with it than Alphys was for just having that doll. She has a little crush on Mad Mew Mew by the way, because it's a living version of her anime waifu. They became good friends and Alphys watched Mew Mew Kissy Cutie with her so that she could understand the lore, because of her Mad Mew Mew is now also otaku. Alphys loves Saylor Moon, Pretty Cure franchise, Candy Love and other kinds of anime. She likes to read yaoi and yuri sometimes.

Papyrus turned out to be a big fan of Iron Maiden. Sans sometimes listen to their songs with him and both skip the songs that talk more about violence because Papyrus don't like it much. What is funny to Sans is that Papyrus' timbre perfectly matches the musical notes of the band's vocalists (especially Bruce Dickinson, who, let's face it, is everyone's favorite) and because of this it is more comfortable and free for him to sing all the notes. His favorite song is CLEARLY Alexander The Great, for obvious reasons. Sans' and Papyrus' favorite album is Somewhere in Time. Sans relates a little to the lyrics of "Deja Vu", but Papyrus likes the band a lot more than him. Undyne likes Iron Maiden too and sometimes sings them on karaoke with Papyrus, both acting and making heroic poses while they sing. Flowey enjoys it too but his kind of metal is a little heavier.

So cute

Sans reminds me of Porco Rosso. It's not a headcanon I just wanted to tell you guys. Their personality is very similar and that's how I see Sans' character.

Sans likes to listen to Iron Maiden with Papyrus but also enjoy some calmer songs. I'm not sure who is his favorite artist, but I think that he would listen a little bit to Lana Del Rey. Especially her latest albums. He really likes the instrumental ending in "If You Lie Down With Me". He knows that some people consider her too "girly" for him to listen, but he really doesn't mind, it's good music after all. He likes calm songs with good instrumental and good lyrics.

Flowey starts living with the other monsters too, like in the "flower pot au". Most of his 'friends' know that he's prince Asriel, but he asked them to call him Flowey, even Toriel and Asgore. When worried, sad or having a deep conversation, sometimes Toriel or Asgore call him "Asriel", mostly Toriel. This makes him very emotional. He's also learning how to develop emotions again and it's being hard. Flowey discovered that listening to metal can calm his nerves, letting it all out. It's very funny to watch a little flower headbanging to a death metal song. He also enjoys singing guttural and he feels better after doing it so. It's like he can express his angry side without harming anyone in the process (Frisk is teaching him how to do it).

Asgore and Toriel are getting well together. They are becoming friends again, even flirting sometimes. Both of them talked about how they felt after those events in the underground and explained their point of view, finally ending that stupid distance. Asgore feels guilty for what he did, and Toriel understands that he had to do it because he thought it was the only option. They've been recovering from the greif of their children and everything seems to be better now. Being eachother's bestfriend again really helps a lot dealing with the guilt. They understand that they had to go and it wasn't their fault.

Frisk is a big AURORA fan due to her pacifist songs. They feel like her songs give them the energy to keep being a good person, caring for other people and helping the world. Papyrus enjoys some of her songs too because Frisk explained to him what the lyrics meant. Frisk tells Flowey that "Churchyard" makes them think of him (he understands why but gets grumpy because of it)(and it also makes them think of Sans, but they never told him because these are memories from other save). Some of their favorite songs are Animal, A Different Kind Of Human, Apple Tree, All Is Soft Inside, Soft Universe, It Happened Quiet. Toriel pretends that doesn't relate to the lyrics of Midas Touch to avoid explanation (she heard Frisk listening to it one time and paid attention to the lyrics, so that's how that happened).

Asgore and Toriel enjoy some calmer songs too. Sans is one of Toriel's best friends, and one day he came to their house and Toriel asked him to put any song he likes. He choosed "Let The Light In", which is another one from Lana that he listens to, and that's how Toriel started listening to her too. Again, only her latest albums (they feel that her older albums are too sad). Because of them Asgore also started to listen to her songs. They like to make "tea parties" for their friends while Toriel brings her butterscotch pie and Asgore makes the tea, hearing those songs playing in the background. It brings such a cozy feeling.

And then the karaoke moment starts and Papyrus and Undyne are screaming on the microphone. Mettaton likes to sing too (sometimes with Shyren), Napstablook controls the audio. Asgore tries, but he knows he's not the best at singing. Mad Mew Mew wants to sing Babymetal, Alphys really wants to sing with her but she's too embarassed to do it so Undyne helps sometimes and encourages her. Frisk dances with them because they're not really into singing. Sans is too lazy to sing and he says that he's not the best at it.

I wanna add more headcanons to this list. Gonna keep updating when thinking about new ones!

The Effects of his Captivity:

I’m yapping as I go so things might be repeated and disjointed sjsheoeb

The effects of solitary confinement for 17–20 years, compounded by erasure from existence, being forgotten by loved ones, and surviving only due to the power of six human souls, would likely devastate Color on every level—physically, mentally, and emotionally.

The scar from the human’s killing blow and the busted skull would constantly remind him of his defeat and the cost of his decision.

The scar across Color’s chest, combined with a busted skull and the fact that his body is only held together by the souls of the fallen children, would cause constant, likely debilitating pain.

The pain would not only be physical but might also affect his nervous system, creating a sense of heightened sensitivity, numbness, or confusion in certain areas of his body.

The missing eye socket and the physical instability caused by the six souls could result in constant discomfort, with his body held together by an unnatural force.

The loss of one eye results in limited vision, leading to disorientation or an inability to perceive his environment fully. His reliance on other senses might have intensified during his long isolation.

Though his body remains animated through the human souls, the sustained trauma would lead to deterioration in his physical form. Despite being “alive,” his body could be slowly degrading, leading to a weakened, frail state, susceptible to further injury or collapse if the soul power fades.

Without natural healing mechanisms, he feels fragile and unstable, living with the fear that even a minor incident could cause him to dust.

Isolation and lack of physical activity would lead to a decline in motor skills. Even with the souls sustaining him, his body would feel awkward or disconnected from his movements due to the prolonged lack of practice.

Being erased and forgotten would create a sense of identity erosion. He would question his own existence, asking, “Am I even real if no one remembers me?”

The replacement by Undyne would deepen this feeling, leaving him with thoughts of worthlessness or expendability. Being erased from existence and replaced as his brother’s sibling could shatter Color’s sense of self.

He might feel like a hollow shell, disconnected from his past, his identity, and even from the idea of family. This loss of identity could lead to deep confusion and a constant struggle to find meaning or purpose in his existence.

Prolonged isolation often leads to hallucinations, disorganized thoughts, and paranoia.

With only Gaster for company, the lack of meaningful interaction and emotional support would likely exacerbate feelings of detachment from reality.

With no one to communicate with besides Gaster, Color would experience intense loneliness. The human need for social connection becomes exaggerated, possibly leading to an almost desperate mental state.

His mind becomes fragmented, with periods of dissociation or even delusions where he might question his own existence, identity, or even whether he truly deserves connection.

He may mentally replay the moment of his decision to sacrifice himself and the souls, analyzing it endlessly and second-guessing if it was the right choice. This fixation could lead to rumination, spiraling into depression and self-blame.

While in solitary confinement, Color’s mind would likely sharpen its focus on survival. This could manifest in an almost obsessive attention to maintaining his existence, perhaps in unhealthy ways like fixation on the six souls that keep him alive or obsessive thoughts about what could have been.

His mental state would likely shift from coping mechanisms to raw, desperate survival instincts as time passes.

The combination of isolation, guilt over his past actions, and the fear of fading into nothingness could cause Color to experience significant paranoia. He might fear being forgotten again, rejected by any potential new connections, or being discarded once again.

This paranoia could cause him to avoid making meaningful bonds, driven by the constant anxiety that no one would ever remember or care for him.

Knowing the six souls are tied to his existence, he feels profound guilt over using their power to remain animated, questioning whether his survival is justified.

The choice to sacrifice himself and the six children to save his timeline would weigh heavily on Color’s psyche. The emotional burden of having made that decision—likely seen as a selfish act, despite its altruistic intent—could plague him with guilt, making it difficult to reconcile his actions with his current state of existence.

The scar, both physical and symbolic, would constantly remind him of the lives lost and his perceived failure.

With no outlet for his feelings, Color could harbor intense anger, not only at the people who forgot him but also at the world that allowed him to fall into such a fate.

This anger might turn inward, manifesting as self-loathing or projection of his frustration onto Gaster or even his past self. He could experience periods of violent outbursts, fueled by the intense emotional overload.

The most defining emotional toll would be a profound feeling of abandonment. Color would be haunted by the belief that no one cares about him anymore, having been forsaken not only by his family but by the very timeline that once needed him.

This abandonment would likely result in a deep sadness and longing for connection, especially with those he once loved. He wonders if he is fundamentally unlovable or unworthy of remembrance.

This loneliness could manifest in a desperate need for validation once freed, making him overly dependent on relationships (e.g., Killer, Delta, Epic, potentially Abyss, Gaster especially.)

Being forgotten by his loved ones, replaced as an older sibling, and erased from existence leave him grieving not just for his relationships but for his very sense of self.

He may also mourn the timeline he tried to save, feeling like his sacrifice was in vain if it resulted in this outcome.

He could harbor anger toward the human for putting him in this position, toward Gaster for not being more helpful in the Void, and even toward himself for making the choice to sacrifice himself.

This anger could fuel a determination to prove his worth or, conversely, lead to a sense of bitterness and hopelessness.

In the face of overwhelming despair, Color might latch onto a mission or role (e.g., helping people, trying to rebuild his identity) to feel meaningful again. His fear of being forgotten may make him try to be indispensable to others, risking burnout or exploitation.

After escaping the Void, Color developed an intense fear of being alone again, leading to overattachment to those who show him kindness, like potentially Delta, Epic, etc. He goes to extreme lengths to stay connected, even if it puts him in harm’s way.

The scar, the damaged skull, and the missing eye feel like visible reminders of his failure. He struggles with feeling grotesque or unworthy of acceptance.

his own suffering make him highly empathetic toward others in pain, particularly those who feel abandoned or forgotten, like Killer. This shared understanding make him a deeply loyal and supportive ally.

The lingering guilt and despair may cause him to devalue his own life, making him reckless in dangerous situations. He might see his survival as unearned and act with disregard for his safety.

The isolation, paired with the trauma of being forgotten, erased, and replaced, likely resulted in Color being emotionally fragile, mentally fractured, and physically deteriorating.

It’s also worth taking into account if Color remembers everything about Gaster again or not, considering that Gaster fell into the Core (was implied to have jumped) and shattered, being forgotten (but not replaced like Color was) by everyone, meaning Sans may not have known completely who Gaster was when he first fell in.

This could result in intense identity confusion and disorientation, because Color holds two dual memories; one where Gaster was present, and one where he wasn’t and didn’t exist.

This could even lead to moments of intense confusion, anger, and fear when one moment he’s talking to Gaster but the next day he’s being comforted and hel by a complete stranger he can’t remember the name of.

His identity felt like something slipping away, with his desperate need for connection turning into a hollow, burning desire. These long years shape him into someone who is deeply mistrustful of others, fearful of being abandoned again, and increasingly haunted by his past mistakes when he finally leaves the Void and perhaps his own timeline.

Prolonged isolation can lead to auditory/visual hallucinations, particularly if Color’s mind tries to fill the void of human interaction. He might perceive the voices of the six souls or even imagine people from his past trying to reach out to him.

The blurred line between reality and memory could lead to moments of psychosis, where Color struggles to trust his own perceptions.

Given that in the caring short, color was all too willing to accept the possibility that he might’ve been seeing and hearing things and gaster is concerned that color was “talking to someone”—makes me think it’s really not a stretch to think that Color likely experienced periods of psychosis in the Void. Seeing and hearing things that aren’t there, feeling things.

I’m thinking the Human, the six human souls, probably Papyrus. If he is aware of what’s going on outside the Void, he possibly hallucinates Ivory/Undyne. he maybe hallucinates stuff about Gaster too, saying and doing things Gaster didn’t actually do.

he could also hallucinate that he’s dusting, cracking and dying, since it appears he probably would’ve died if the souls hadn’t kept him alive (and then later Gaster.)

Would also make sense if he’s hallucinated things like Undyne deliberately and knowingly replacing him, resulting in emotional anger, betrayal, hurt, jealousy—even if he logically knows the things he saw and heard weren’t real, and that Undyne doesn’t even know who he is anymore, he struggles to accept and realize it emotionally.

Without consistent access to nourishment (magical or otherwise), Color’s body might develop long-term issues like fatigue, atrophy, or brittle bones, especially if his skeletal structure is already prone to fragility.

Since Color has only one functioning eye, the prolonged isolation and lack of resources would worsen issues like eye strain or headaches, especially if he spent significant time in the dark or staring at the infinite void.

Lack of movement and injuries from past experiences (like scars from battles or trauma) could lead to persistent joint or nerve pain. The stress of isolation might also amplify his perception of physical pain.

The Void’s timeless nature likely eliminates a natural day-night cycle, leading to chronic insomnia or fragmented sleep. This, combined with emotional stress, could result in long-term physical exhaustion and cognitive impairment.

Being erased from existence and forgotten by everyone he cared about would challenge Color’s sense of self, potentially leading to derealization (“Is this real?”) and depersonalization (“Am I real?”).

His fragmented sense of identity, already influenced by the six souls, would likely worsen as he struggles to distinguish himself from the traits and voices of the absorbed souls, if he can hear them.

The lack of stimulation in the Void might cause memory issues, difficulty concentrating, and slowed processing speeds. He could struggle to focus or retain new information, especially after being released.

Being forgotten by everyone would reinforce a sense of worthlessness, as if his existence didn’t matter. At his worst and lowest moments, this could lead to chronic self-doubt, difficulty asserting himself, and a tendency to self-sabotage, believing he doesn’t deserve to be remembered or loved.

Being trapped in the Void with Gaster might lead Color to view existence as fragile and easily erased. He could develop an obsession with permanence, fearing that any connection or achievement could be erased just as easily as his past.

The loss of his family, friends, and timeline created a devastating sense of isolation, leaving Color craving connection while also fearing abandonment.

This might result in a desperate need to form bonds once freed, even if those bonds are unhealthy. Difficulty trusting others, as he fears they might leave or forget him again.

Knowing someone else, Undyne, took his place in his family create deep insecurities. He fears that even if he reconnects with Papyus, he won’t need or want him back. This could manifest as a reluctance to reach out to people he once cared about.

Clinging to anyone who shows him kindness, even at the expense of his own well-being. Overcompensating to prove his worth, becoming overly self-sacrificial in relationships.

While Color may not initially recognize it, he could harbor deep resentment toward his family for forgetting him, even though it wasn’t their fault. Toward the universe or fate for placing him in the Void and taking away his life. Toward Gaster for being his only companion but unable to provide meaningful connection.

Color would likely cling to memories of his timeline, romanticizing his past relationships and home. However, these memories might also bring deep pain, as they highlight everything he’s lost.

With Gaster his only companion, Color likely formed a complex bond with him, oscillating between gratitude for his presence and anger at being trapped with him.

Gaster’s cryptic nature frustrates Color, making him feel even more isolated, as Gaster does not fully understand or validate his emotions.

If Gaster provided guidance, Color might cling to him as a surrogate figure of authority, even if the relationship was unequal or strained.

Alternatively, Gaster’s enigmatic personality could exacerbate Color’s paranoia, making him question Gaster’s intentions or reliability.

After escaping, Color might constantly watch for signs that people are about to abandon or forget him again, leading to heightened anxiety and paranoia. He might try to make himself indispensable to others, fearing that if he isn’t needed, he’ll be forgotten.

While Color craves connection, he might avoid deep relationships at first, believing they’ll only end in rejection or loss. Guilt and feelings of unworthiness might lead him to push people away or avoid opportunities that could bring him happiness in the beginning.

Eventually he may surrounding himself with lots a connections and community, caring for each one and desperately not wanting to be alone again—finding the pain of being alone outweighs the potential pain of rejection and loss.

He knows many people but he often avoids talking about himself too much—possibly feeling that it’s pointless to try and explain, or more likely, not having the words to explain. Not knowing how to word it, how to explain in a way others could understand or relate to.

Broke: Undyne doesn't let Papyrus join the royal guard despite his immense battle prowess because she believes that he's too naive

Woke: Papyrus can't join the royal guard because it's disproportionately made up of dogs who stop all productive activity to play with the tall bone man if he was at the official meetings

[haveyouseenthisskeleton]

Undertale characters see S/O break a bone and then S/O basically just does a Far Cry healing animation and doesn’t even care they got hurt.

Undertale Sans - He grabs your arm gently but firmly, with dark eye sockets. "b u d d y ? N e v e r d o t h a t a g a i n." He hated every second of it. What's wrong with you? Go to the hospital like a normal person, you're going to hurt yourself more.

Undertale Papyrus - He faints. First, the shock of seeing your leg on the wrong side triggered him, but you simply putting it back in place like it's nothing? That's too much man. He can take a lot of things, but this is a big no.

Undertale Toriel - .... She was about to heal you, that for sure stopped her dead in her tracks. She's speechless. And immediately turns into Goat Mom mode and starts lecturing you about how dangerous this is and how it could have hurt you even more. Now you sit down this instant and you let her heal you properly.

Undertale Asgore - He lived hundreds of years and still discovers new things. Though, that one is maybe a bit too much. The noise of the bone snapping back into place made him so uncomfortable he suddenly panics his way out of the house, pretending he needed to get groceries or something.

Undertale Undyne - She stares in awe for a few seconds. Then she explodes. "This was AWESOME. Do it AGAIN!!!" She's very excited about this. She's even ready to break your arm if you need it! Come on!

Undertale Alphys - The scientist in her leaves her body. Why even try? You clearly have no idea how to fix a bone. It's so dangerous and you just act like everything is alright now??? How??? You should be screaming in agony???

Undertale Frisk - Well they can do cool things too. Frisk immediately struggles to lick their elbow with all they have.

Undertale Chara - They roll their eyes at you. You think you're in a video game or something? They're not taking you to the hospital when you realize you're dying because of how painful this is. You did that to yourself.

Undertale Mettaton - He gasps, then runs to you with a camera. Can he break one of your bones so you can do it again and put it in his next movie? Please, please, please, pretty please....

Undertale Gaster - He hisses at you, all his goop puffing like an angry cat. This is the worst sound he has ever heard, please never do that again or he's going to blip into another dimension again!

Undertale Grillby - He stays neutral, but his fire body suddenly burns for real, which means you triggered him. And now the bar is on fire, and Sans is on fire, and all the customers are running in circles screaming for their lives. What have you done?

Undertale Muffet - No big deal, it happens all the time with her eight arms too. She doesn't even notice when one is broken with time, as she has seven other functioning ones. You're not special, who cares.

Undertale Burgerpants - Oh look at that. He's dating another weird person. Welp, that's official. He has a type apparently. He wishes he didn't have one. Why can't he date normal people who do things like normal people should?

Undertale Flowey - Did you just pull out the friendliness pellet he threw inside your arm with your teeth? "You can't do that! That's illegal! I just broke that bone, you can't fix it like it's nothing! Cheater!" He's so mad! Stop breaking his fun. He wants to kill you!

Undertale Gerson - He wiggles his eyebrows at you. You know his back is hurting as well, right? You know. A little trick like that could help like hell. Come on. Don't be shy.

Papyrus Crush Headcanons!!

here's the sequel everyone! Come and eat up

you're one of Papyrus's first crushes

honestly so he's pretty unsure of how to act around you

lots of blushing, stammering and running through windows

you figure out he has a crush on you pretty quickly

so the two of you sorta end up in this weird grey situation, he doesn't know if you like him back and you are to afraid to confess

you spend a lot more time together

he's always coming up with some sort of reason to be with you

"HUMAN! YOU MUST COME OVER! I AM MAKING MY FAMED PASTA FOR DINNER!" of course you oblige

Sans is always nowhere to be seen, so the two of you end up having lots of romantic tension in these 'dates'

wants to help you lots

Need help cooking? He's there, need help moving a box? "STAND ASIDE HUMAN! THE GREAT AND MAGNIFICENT PAPYRUS SHALL HELP YOU!"

He runs to Undyne for help, she then proceeds to laugh her ass off at his predicament

though she does agree to help

so know you have both Undyne and Sans playing matchmaker whenever they get a chance

At one point Undyne just shoves you two into a closet to get it over with

He's constantly messaging you through the Undernet, just little updates on his life

when he finally gets the courage to confess his feelings

he trys writing a letter, yanno, just so he can't fluster himself

it's beautifully written, talks about your history, what he admires about you, why he feels this way and at the end he asks to be your partner

[sysig]

Don’t be silly! Okay, be a little silly (Patreon)

[justali-anne]

One of my favourite headcanons to revisit is the idea that Sans actually goes by his middle name and his full name is Comic Sans (insert last name here).

Like, it's just so funny to me.

Like maybe in early childhood or something Sans thought, "being called comic is dumb," and decides to just go by Sans. And Papyrus is the first person he told because who else would it be?

Maybe even now, being called "Comic" on its own would be a surefire way to annoy him, even mildly. Don't call him Comic. He will not respond to it. He will, however, respond to Comic Sans.

It sounds like something Papyrus could annoy him with too. Like if Sans is ignoring Papyrus or something, Paps would get in his face and address him with the most deadpan, smug voice, "COMIC," and Sans will respond with a, "don't call me that."

Can you imagine how the others would react too? How would Toriel react? How would Undyne react? (I bet Undyne will make fun of Sans for it, but, y'know, wholesomely).

Imagine if everyone finds out and starts calling Sans "Comic" for a week straight. Oh, the hilarity!

[fandomfrogz]

tears out my hair while yelling about undertale

here are my super-important-need-to-be-in-works-for-me-to-enjoy-them list of facts

- frisk, chara, napstablook, and monterkid all use exclusively they/them, if you dont imma pop you b/w the eyes

- chara isn't evil cant believe I have to say it, no they dont influence the player/frisk to be evil

- papyrus isnt stupid nor is he particularly naive, he actively believes in people and their ability to make the right choices. He wants to bring hope and sometimes just being joyful is a good way to do that.

- sans dosent remember the resets, this is a cannon fact as he includes himself in the 'we' he references loosing all memory of it. However he knows OF the resets and likely can deduce whether one has occurred wether through the canonical dejavu characters posses or just his timey whimey shenanigans. I just think that distinction is important.

- sans likely has a sleeping disorder of some kind, being lazy is definitely a part of it however falling asleep standing up is kinda weird (also i have a sleeping disorder and hes literally me)

- alphys' experiments with DT were consensual. Thats a big one i think, yes she souldve shared what happened with the experiments but she had no way of knowing what would happen and she had permission from the families. defo a big one in understanding her character.

- both undyne and sans dont perceive papyrus as weak nor stupid, they just both have experienced a facet of the world that has imposed the idea that kindness can get people killed. Also assuming undyne knows the humans were kids i dont think she would wanna push that on anyone especially not someone she dosent think WOULD kill them.

- Papyrus also purposefully puts on a front of slight ignorance in front of sans (canon), my personal explanation for this is he wants to help sans but understands how secretive he is and instead will rib him to take care of himself for papyrus' sake.

- Toriel and Asgore are both flawed and grieving. toriel was so wrapped in her worldview that she abandoned her people and also the possibility of preventing asgore's policy from being implemented but she also was grappling with the loss of her children and her husband vowing to kill children just like her chara. Asgore made his policy in rage and grief but also vowing to kill children 'for mosterkind' isnt enough. overall they are complex and neither is 'right'.

theres more but i need a nap.

Some Undertale gamer headcanons:

Someone said that Toriel would be the world Tetris champion, and I'm not sure why, but I agree with that. And not just Tetris, but bubble-poppers, match 3, marble-shooters, all of those kinds of games. She's the new Candy Crush mascot.

I've also seen people say sans would be into rhythm games, and... no. Why would you think he would be into something that takes that much effort? Seriously, come on. What sans is into is farming sim games. He's written dozens of online strategy guides for Stardew Valley, all of them under different pseudonyms.

Papyrus is into online multiplayers. All of them, any genre- Fortnite, Apex Legends, Fall Guys, Elder Scrolls Online, Runescape, you name it. He sucks at all of them, but none of his online friends is willing to tell him how bad he is because he's so darned innocent and nice. Nobody really wants him on their team because he'll always make them fail the mission, but he's so upbeat and uplifting that no one has the heart to tell him they don't want him.

Undyne loves Souls-like and dungeon crawlers, but she struggles with anything that requires stealth, she just doesn't. do. stealth. She says it's stupid to have to sneak up on enemies, she should just be able to barge in with guns or swords or spears blazing in any and all circumstances. Don't ever even suggest Metal Gear to her. Or Breath of the Wild- she rage-quit after the Yiga Clan Hideout quest (although it did leave her with the impression that bananas give you strength in battle, so she now always keeps a bunch of bananas on hand).

Blooky plays solitaire and Mah Jongg, and even those stress them out.

Maddie plays casino and slots games. On an unrelated note, she's always broke.

Mettaton is the rhythm games master. You will not change my mind on this.

Alphys is HEAVY into JRPG's. The more anime it looks, the more she loves it.

Asgore has no idea what a video game is. Well, ok, he has some idea, his kids both played games, but he never could figure them out. He thinks Sonic and Crash are both Mario characters and that Link is a girl- you get the idea. But he did used to play card and board games with Toriel. Especially chess (she totally owned his ass in every match). Ever since Toriel left, he can't bring himself to play chess. He plays checkers a lot, tho. He usually loses (he plays against himself).

Asriel and Chara were into action/adventure games. Asriel's favorite characters were Yoshi and Link, while Chara's favorites were Samus and Shadow the Hedgehog. What? No, I'm not projecting my favorite games onto the Dreemurr kids. What are you talking about?

Frisk has only ever played the hit indie game Undertale. About 500 times. Always Pacifist, they've never even tried a Geno run. They've been thinking about playing that Deltarune game, too, but they kinda wanna wait until the whole thing is released.
