Yanberry and Timber with a crush that has super fluffy long hair ? 😤😤😤

Yanberry: Do you like your hair? Do you dislike your hair? If you don't like it, hey, he could cut it for you! If you complain about it enough, he just might, but also he might not if he does like it. He's a strange guy, very strange, and sometimes not very good. I will admit it. Anyway! If you do like your hair, he will get you special stuff for it! Stuff that would help it and help you have an easier time taking care of it. He likes how soft it is :)

Timber: Expect to be randomly pet at times. He doesn't really see a reason to NOT do that; I mean, you are his future datemate, so he should be allowed to pet you. He enjoys putting your hair into different styles, and shockingly, he is pretty good at it! He knows what to do and what not to do, and his sharp fingers are good for brushing through it without cutting you or anything. It's honestly really cute how interested he seems in your hair. Sometimes he would get distracted while playing with it, and he would accidentally stop listening to you if you were talking. It's not his fault! He has a lot of issues, mostly in his head. Don't get mad at him; just get his attention again, and he will pay attention to you.

Platonic yandere Flowey headcannons if you don’t mind of course.

Thank you for requesting! Wasn't expecting flowey of well characters to get requested, but I have nothing against writing for him :3.

🌻Okay I genuinly have no idea how do you get flowey to be a yandere for you, look at that little asshole!

🌻 The only way I can KIND OF see him becoming one was if you reminded him a lot of the fallen child (im not calling them chara)

🌻 But anyway, flowey is your platonic yandere, so what does that mean?

🌻Well he'l be MUCH nicer than normal flowey, or at least will try to be.

🌻But that niceness is only for you, to anyone else he still would be extremely mean :( (and that is putting it lightly)

🌻 Flowey would be kind of like a realy clingy younger brother, but you know more dangerous.

🌻 He'l make sure you don't have any contact with other monsters, most likely keeping you in some abondoned part of ruins.

🌻Like I said he is trying to be nice, but if you try escaping him some of his more sadistic tendencies might become noticable.

🌻 Flowey won't hurt you... Much. But Hey, few friendliness pellets aren't much, are they? ;)

🌻 Of course he will not kill you, that's the last thing he wants. He may be an absolute asshole but he still cares about you! He just doesn't care about your feelings~

It isn't the best I ever done, but still I Hope it's good enough! Like always im open to criticism! Sorry if it wasn't good :(

Hi. Can I have some hc of platonic yandere uf frisk with a human!monster friend (like a vampire, zombie or ghost)?

Underfell Frisk

Fawn hates monsters. She hates them so damn much that she had committed genocide over and over and over and over again. The only reason why she ever stopped was because Dessy begged her to. So when Fawn finally got to the surface and found out that there were filthy monsters up top too, she was out for blood.

She met you while on her usual monster hunt, killing whoever she found. But then, something made her stop when she saw you. You looked so human. She wouldn't have known you were a monster if she didn't notice your fangs. And for some reason, she felt drawn to you.

"Just a few minutes," she told herself, as she sat down to talk to you. "Just a few days," she told herself when you two exchanged numbers. "Just a few years." She repeated to herself when she started to feed you on her blood, so you could not eat anything else but her blood.

You reminded her of Dessy. Sweet, a bit naive and so very obedient. You were so damn perfect, she could forget you being a monster.

Idk if your still taking for undertale but can I request general yandere for sans the skeleton ? If not please ignore :3

Ofc I'm still taking Undertale! Thanks so much for the ask :D!

Though I don't know if you want headcanons or a oneshot or something so I'll just do hcs if that's okay!

[Warnings: General obsessive behavior, implications of stalking, and possessive behavior.]

Yandere Undertale Sans Headcanons

Sans, at least from an outside perspective, is relatively chill, laid-back, and is still the lazy charmer we all know him to be

He can be a little protective, sure but that's normal, right? Yeah, sure, it's nothing to worry about! After all, just how much can a lazy skeleton really do?

Well, that's nothing for you to worry about, at least not early on.

At the beginning, Sans is... well, Sans!

He's funny, he'll pull a few pranks here and there along with dropping a bad pun every now and again. He's sleeping all the time and loves to scare you whenever you think you're alone and just does his thing. He's a funny lil' guy!

It's so normal that it's almost scary in this case.

Until it isn't.

Sans isn't one to form deep connections easily, and though he can be social it does take more effort for him to actually have friends or just other people in his life that he can be close with like how he is with Papyrus or even close to that point.

So when he does it isn't just a big deal, but it seems that when it especially comes to you (no matter the relationship you two have), it changes the whole game

Almost completely out of the blue, how Sans acts completely shifts over entirely, but if you don't know where to look or don't have a careful eye then it will be tough to even notice the tiniest change. Though sometimes it can be easier to see it, if Sans catches on that you may have noticed something then he'll try to be extra careful.

Which means that some of the little details that were fueling your paranioa now seem to either completely gone, or are much harder to find. Though, don't be so easily fooled.

For you see, now some of those habits of his don't seem so normal or healthy anymore.

Everytime Sans sleeps, he not only uses it as an opportunity to be unreasonably close to you, but he also uses it to take little things you probably won't notice but have some value to you.

If by chance he takes something that you're trying to find, he'll just give it right back after a few moments of watching you freak out, and claim that he found it in a place or location where you'd normally find it... but you could've sworn you checked there already- but that doesn't matter, right?

Maybe not the first few times, but after a little while it gets weird.

As for all the stuff he gets to keep? Well, he has a special place for that in his room, and it's like keeping small parts of yourself with him. He loves it, but you'll never find it.

His little 'scares' seem to be worse too, but only in the sense where they seem to happen when you not only least expect them, but when you really are all alone. It's almost strange, like he's always there, but you know he isn't. Right?

Yeah, sure, sure.

Moving on, Sans still is a guy full of jokes, and yet his little pranks seem to be a tiny bit more targeted now.

People you hate now live their lives just a little more inconveniently, and though it seems small it's the little things that can make your day all the more worse or better.

People who hate you now have to be a little more careful as they might 'risk' making an embarrassment out of themselves in front of their colleagues should they run into one of Sans' pranks. For, if they aren't careful then they'll get a bucket of water spilled on them once they enter a room, or sit on a whoopee cushion during an important meeting.

You're friends and loved ones, however, have it worse.

Tar being spilt on them, being tased for a short while, getting their fingers stuck in mousetraps, stepping on legos or thumbtacks- its bad. It's so bad that some even begin to draw away, why?

Well, that's because it gets worse with each and every 'prank'. So much so that Sans just so happens to create an opening for himself, and solve every little problem he's been overthinking and worrying about ever since you both began talking.

Sans is lazy, but lazy people who procrastinate tend to find the most innovative ways to do things as a means to make their lives easier in the most convenient way possible, especially if their smart.

Sans is a charmer, a listener, so he knows every little thing about you and everything you know about someone. He uses his little charm to get more information out of other people in the most natural way possible as he butters with up with jokes and barely even has to lift a finger before everything he wants comes tumbling out. His popularity helps immensely in that aspect, and so does his way of coming up with believable excuse and reasons on the fly.

He uses what he knows to his advantage, and that begins to show when all your loved ones begin to pull away, and even those close to your loved ones are keeping their distance and supporting your loved ones' decision.

It isn't too long after that you're cut off entirely.

Sans is a patient guy, he can wait for the results for as long as it takes (until a certain point of course), and wouldn’t you know it- his patience is handsomely rewarded.

And the funniest part of it all is that you still don't even know it until it happens.

When it all crumbles down on you and smacks you straight in the face, it hurts so badly and breaks you apart so terribly that all you can do is turn to the one person who never left you. Who you knew would listen and would hear you out as you sobbed out your worries and woes.

Sure, Sans might have acted a little weird on the outside, but like his brother he isn't that bad of an actor. People are easy to read, so it's easy to see what topics to avoid and what to change to not spark something

You are no different

And Sans is content with that, and others may be wondering why he didn't kidnap you or anything, but that's the thing isn't it?

Why would he need to do that and go through all of that trouble when you're right here in his arms, and right where you're supposed to be? You may not know it, and Sans might not say it, but this is all he's ever needed and wanted.

You, here with him, in the comfort of his home. Away from anything and everything else as it almost seems like it's just you and him in the entire world.

Why would he lock you away when you came to him all by yourself?

That's because he doesn't have to, so he didn't. Either way he got what he wanted, what he needed, so it's not like he cares anyway.

I just hope you like cuddles, because you're getting a ton of them.

Sans will make you second guess all the people around you until all you can be sure of and depend on is him.

He'll shape your world in a way where he's your only sense of comfort, he's your own safe space. Where his home is the only home you know.

Sans isn't trying to make the world seem like a bad place, and sure there are decent people out there, but who can be better than him? No one will ever make you feel as safe, seen, heard, or comforted as Sans, so it doesn't that there are others out there who are decent? None of them can give anything that Sans hasn't already given you.

That's what Sans wants to show you and help you understand.

The world isn't all the cruel, but isn't it better with him around?

-----------

Kind of rushed, but I hope they're okay! Sorry it took so long! I've been scavenging for motivation-

[lightfeltmemories]

Hello! I'm the same guy who requested the Starlo thing lol thx for letting me know! Possibly instead could I get some Yan HC's with Starlo instead please?

starlo / north star : yandere headcanons

note: sorry it took me some time to get to this, i was dealing with some stuff irl not to mention some light writers block lol, so, if this seems half assed i apologize greatly.

tw: please be mindful that these are yandere headcanons, meaning there will be depictions of unhealthy obsessions and toxic relationships, please do not interact if this type of content is not for you, scroll away or block, this post is labeled 'mature' for a reason.

starlo hasn't really though about romantic relationships much as of late, especially after ceroba married chujin, he didn't think he'd ever find someone else, until you had came along, stumbling into the wild east, it's like something in him had changed, and everyone else would see it too.

he would find himself getting jealous at anyone who flirted with you, despite both of you being very single, and you (most likely) not viewing him romantically, and just.. the sheriff in this small town.

when the two of you do manage to get close, he's always there, not always always but you'll usually see him nearby a lot more than usual, he uses the excuse of watching over you to make sure you're safe or aren't doing anything illegal, the latter being more on the playful side.

the obsession would be worse if you were a human, starlo is quite literally obsessed with human culture (more specifically wild west culture) so an actual human coming here would excite him greatly (pretty much how he was with clover but obviously in a romantic sense.)

you become apart of the fiesty five immediately depending on your skills, everyone can sense that you are favored amongst the rest which causes some in fighting.

he is fiercely protective bordering overprotective, he gets jealous easily when someone flirts with you, and when you talk to him about it, he tells you that it's to make sure no one creepy tries to hit on you, which makes sense in a way, he isn't the type to kill people for looking at you but he's also kind of just really... insecure.

Base Yandere Sans Headcanons: Perfect Run (Undertale)

[Hello My Sexy Muffins, and welcome back to another spooky day of the spooky month. I had a lot of premade chapters and videos before October which is why I have not mentioned Halloween or spooky month. Anyways I hope your spooky month is going well. Anyways this chapter is Sans please Enjoy!]

(Disclaimer: Sans is not yandere in canon, this is just for fun. It is not to be taken seriously at all. Simping for fictional Characters and Fictional yanderes is fine. As long as you separate fiction from reality. Yanderes are not ideal partners to have in real life.)

Once again please enjoy!]

-Base Yandere Headcanons With Sans-

.Sans is a chill but lazy guy most of the time.

.Though there are times that he can be serious.

.He is aware the timeline resets and he knows what is going to happen each time.

.That also allowed him to spend time with you over and over again.

.You were never at risk of him losing you.

.So he could continue to live a life with you over.

.He would let the timeline go on over and over.

.Though soon it is not enough for him he needs to be able to confess to you.

.So he would learn the perfect way to confess his feelings for you.

.So that you will never turn him down.

.He studies the timeline and for you, he would work on a way of breaking and stopping the reset.

.He needs to be able to make you his and his alone.

.He also loves a good joke and loves to tease you and make you flustered.

.He loves the reactions he gets out of you making you a mess or flustered or even irritated with him.

.He is also very observant with his yandere side.

.So he learns everything that makes you smile and laugh, and the things you do not like.

.He makes sure that he is able to learn them and able to use them to help him make the perfect run.

.He is a bit of a stalker as well, always around you, never leaving you alone and watching you.

.Sometimes he will make his presence known, other times not.

.He cannot let you be hurt and if you were he would show no mercy to the person who hurt you.

.He would destroy them and make them suffer for daring to harm you.

.You are his to keep safe and that is his job if he fails he has failed you and has failed his love.

.He is a vengeful yandere that will do anything to avenge you from whoever tries to seduce you or take you from him.

.He learned everyone that who is a threat to him will get rid of them accordingly.

.When he has finally made the perfect run he will break the timeline and there he will confess to you.

.You of course say yes because he made sure you would.

.He tried and tried again until he was certain you would be his and his alone forever.

[YASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS another chapter is done, I hope you all enjoyed it and stay sexy all of my sexy and spooky muffins.]

Yandere Toriel Headcannons/Story

"My child, you are safe now."

I see Toriel fitting numerous yandere traits, obsessives, overly protective, and maybe possessive.

But I think Toriel better fits being a protective yandere than the other traits.

When you fell into Mt Ebott, the first thing that hit her head was how defenseless you were.

She concluded that the reason you fell had something to do with that—You were only human, after all—who knows what somebody could do to you, especially Asgore.

So the first thing she did was obvious—bring you to her home. 

She picked up your unconscious body off the ground, bringing it to her home, eyeing anybody who saw your body, giving them a stern look.

Obviously, it scared off most monsters, anybody who could harm you.

And once you woke up in an unfamiliar home, she was happy to know to inform you are safe now, the reason why you fell doesn't matter now, what matters is you are safe with her.

At first, you were confused, but after a warm welcome and some pie, cinnamon, and butterscotch, you got used to it.

Toriel would blow off any attempt you would induce towards asking about escaping. she wouldn't leave out of frustration and attempt to destroy the door. Instead, she would slowly get more irritated towards your attempts.

"Your safe now, my child; stop asking me such silly questions."

Eventually, you stopped and accepted your fate; you weren't that determined to get out of the mountain anyway. Considering your home life with abusive parents, this is better than in comparison.

Toriel loved when that happened, happily began loving you more, and slowly got more attached. At the same time, however, she began thinking about how feeble and fragile you were.

Sure, you were human, but humans can be weak, sick, fragile, and easily break under pressure; you were only twenty, so young compared to her.

She was fine if you stayed home; the big outside scary world that only she could handle bothered her.

And it continued to bother her, even if you were in a completely safe place, with safety equipment, bicycle, bike, rollerskates, or likewise.

And she freaked out once you got hurt, taking you from the outside world in the safety and comfort of her home.

"My child, I should have never trusted you."

It was then that, over time, she slowly began limiting your venture, don't stay outside past nine and don't hug others without her permission. Don't go away far from home, and the list continues.

You could tolerate such actions that Toriel induced onto you.

After all, better than what your parents did; your father verbally abused you while your mother physically beat you, belt or fist otherwise.

However, Toriel slowly became overbearing, starting to weigh upon you like an anvil increasing in size on your back.

"My child, you were not earlier than I expected you to be here, are you hurt, damaged? Did someone take advantage?"

Even when you confronted Toriel, she would always make up some excuse to justify this behavior. 

"Humans can be weak too, y'know; a good mother cares for their children."

The overbearing continued until one day, she outright banned you from going outside without wearing a full skateboard protective gear ever again.

You had enough of this; she had demanded too much from you, and this was getting ridiculous.

So you confronted her early during the day, letting her know that you had enough of this nonsense and wanted it to stop.

However, she shrugged it off, and when you repeatedly confronted her, she began to become more annoyed and irritated at you.

She lost it for the first time when you gave her a choice, either let the protection off or find a way out of this mountain.

And when she lost it.

She hit you.

At this moment, you realized something; she was verbally abusive when crossed, just like your father, and now becoming physically abusive, just like your mother.

"My child, where are you going!?"

You dashed far from her as possible, exiting the house, dashing around the ruins, seeing everything as a blur, and tried to make some feeble attempt to escape.

And Toriel chased after you in a hurry with tears down her face.

You caused some pillars to fall, some scraps around your body, entering into some water to escape. 

Still, nothing seemed to bash Toriel off, even when she was herself hurt.

Even when monsters came to your service blocking her path, you realized nothing was stopping her, as the dust began to form as you looked back.

Eventually, the monsters that wanted to help disappeared, and your vision was dusty and dirty from the monsters she killed.

That's when you heard her voice, "My child, you should have never left me."

You never did, as she kept you in her house locked up.

Forever.

After all, it's for your protection.

The yandere prompt “Don’t be scared baby, I’m not mad at you, I never could be mad at you. It’s them.” with Axe would be lovely!

I decided to swap it up a little >w>

Axe has been with Y/n for a few months now. Almost a year! He was very happy that he had a datemate—someone that he could trust and someone who could love him. He was very careful with them all the time! He knew that his claws could cut and his teeth could tear.

He always worried that he would accidentally hurt them.

But the other humans? Yeah, Axe didn’t care too much about them. Some were kind, while others saw the monsters as, well, monsters. Creeps that shouldn’t be above ground. A lot of those people always shouted, “Go back to the underground!” Or “monsters should have all died down there!” and that always made Axe upset.

Sometimes he wished that he did die down there; the ones that died were the ones that got out of it the best. Luckily, slowly, monsters were healing and getting better… even if pretty often cops shot them and monsters were treated badly compared to humans. People always assumed the worst about them.

It made him annoyed.

Today he was at the park, waiting for Y/n to get there, picking at the grass beside him. He liked sitting outside! The soft smell of grass and the breeze made him pretty happy. It was nice to relax and get his mind off stuff.

He should have been paying attention, though, because suddenly he heard a voice, and when he lifted his head, it was because the person seemed to be talking to him. It was a human girl that he didn’t know, but she was glaring at him and pointing at him, “Don’t you know that monsters aren’t allowed in this park?” She spat the word monster like it would make her sick.

“Hmmm… n…no?” he slowly shakes his head, frowning as he listens to her talk. “Anyone is a…llowed here.” He had been getting better with talking over the years of being above ground, though he still sometimes had issues, as he would admit.

The girl starts to shout and yell at him, making him clench his teeth, and he digs his finger tips into the ground under him, tearing through the grass easily. His tail started to whip back and forth quickly, clearly hinting that he was starting to lose his patience. All he had been doing was sitting here! Why was this woman going out of her way to get mad at him? And now people were staring.

He sank down, as if that would make him any less noticeable. He was a giant monster! A full 8’5, giant even when sitting down.

“Hey! What the hell are you doing?” they both heard, and they both looked to see that it was Y/n! He smiled just a little and raised his hand, waving at them. They rush over and snarl at the lady, “Leave him alone, you crazy woman.”

“Cra- I am just telling this gross monster to go away! He’s breaking the law.”

“Tell me which law, or get the hell away from us!” Y/n shouted, holding up their hand in a fist. The woman seemed to not want to fight because she cursed at Y/n then turned and walked off, huffing and puffing.

Axe looks at Y/n, seeing a strange yet familiar look in their eyes. It was a look that happened whenever other people talked to Axe… he put his arms around them, pulling them close to his chest, and nuzzled them, mumbling, “You okay? Not… mad at me?” he felt like he needed to ask that.

Y/n looks at him and lets out a soft sigh before hugging back and giving him a nuzzle as they mumble, “Don’t be scared, baby; I’m not mad at you; I never could be mad at you. It’s them.” they sigh out slowly and press a kiss to his skull. “I’m sure she won’t bother you again, and if she does, tell me and I’ll handle her.” he looks at them and smiles, nuzzling them back as he purrs.

They had a strange scent to them that reminded him of blood, but he decided not to question it. He was probably just imagining things.

I've recently been inspired by the aesthetics of the Yandere simulator, creepy glitchy pictures and "Guro". I decided that this would suit my humanization of Error, like, why not? it was originally created by me out of love for Error and creepy girls. so I can make her as weird and outlandish as I can🎀

(lol, I just now realized how strange it is for her to be a Yandere, like, to be in love with someone so much, considering that she's supposed to be aroace... okay, never mind..?)

What if nightmare’s S/O went on a mission without nightmare’s consent then dies what would nightmare’s reaction be?

Nightmare Sans

At the beginning, all Nightmare could do is feel rage. Then, he would laugh. And laugh. And laugh until all he can do is cry. What else is there to do when your loved one dies. When you probably died thinking that he hated you.

At the beginning, he would try to find you in other AUs, but it wouldn't take long to realize that even if they look like you, they simply aren't you.

Nightmare would live in what ifs after that. What if he wasn't so controlling, would you have told him you were going? What if he told you he loved you? Would you still be here? Would you be in his arms instead of six feet underground?

You aren't being a bother, and thanks for the ask!

[Warings: Mentions of Stalking, Obsessive Behavior, and general Yandere Tendencies]

Yandere Gaster Headcanons

Gaster... is a tricky case in general.

He's already an odd ball. Smart, very much so- even to a scary extent, but odd nonetheless.

His mannerisms are strange, and no matter how you meet or how he notices you, it's bound to be just as strange.

It couldn't be clearer that he is a skeleton of science, and really does know a thing or two about what he talks about. However him speaking through hands does take some getting used to.

However, him after and before the core incident does determine just how 'strange' of a character he is.

If you knew him before the core, then he had his own sarcastic but amusing charm, and overall wasn't that strange. Maybe even normal.

He would always try to be so serious while saying the most ridiculous things as a joke, and if you were quite the joker yourself then he'd just stare at you as he held back a laugh, and be internally amused on the inside.

With time, of course, you'd get to see that wall of seriousness he puts up slowly crumble, and even if its nice at first, as all things are, it becomes strange later.

He brings you snacks and little knickknacks to show he cares, and will especially leave you your favorite drink if he sees that you're having a bad day, and uses that to have a conversation with you.

Little moments and things matter a lot to Gaster, so somewhere down the line he tries to share these things with you. It starts off with them being every now and then, but eventually it does escalate.

No matter what he is doing, he tries to rope you into it somehow even if you're the least qualified for the task. No matter what you are doing he tries to include himself.

At a certain point, it almost becomes oddly difficult to do much of anything without him or for him.

Sure, you get to spend a lot of time with him and get to know him better, but wouldn't it be nice to have some time to yourself?

If this is brought up then Gaster will seem to stop, but every time he loses a chance to spend any kind of time with you is another moment you feel like you're being watched in an empty room. Every moment 'wasted' without him is another day where you don't feel alone in places where you should.

The paranoia will most likely never leave you, and it is because he is always there, but just without you knowing.

After all, he has to catch and see what you're doing without him, and he has to take note of who had forced you to not see him as much anymore.

He knows you care about him and cherish your time together just as much as he does, so he has to catch the culprit. Gaster swore that he would get to the bottom of this the moment you even suggested such a thing.

The only reason he hadn't stepped in yet was because he needed to lure the person out with them thinking that he had really stopped. Because it had to have been someone else.

Though if it was you then Gaster supposed he was playing you as well, for he still got to see you every moment he wished.

And it will never stop, not until the core incident happens, and finally you are free. Even if you don't remember why you were paranoid in the first place, and feel like something is missing. Unlike some others you find yourself not minding as much. It's like a weight had been lifted that you didn't even know was there or why.

As for Gaster? Its a tragedy. A terrible, awful thing that just happened to a monster who wanted nothing more than someone by his side, no matter the way it was done.

All his time spent in the void was time soent thinking of you, and so the planning began and never once stopped, and once he left this awful place, you'd be his.

If you'd be his partner or friend forever- it didn't matter, not to him. As long as you were his, he didn't care and now he just had to put his mind to the test, and find a way out.

Him escaping wasn't a question of 'if', but a matter of 'when', and when he does — it would be the end for you.

It would be the end of your current, peaceful life without him. The end of your friendships and or any relationships you have with anyone no matter what.

He would make sure that it would just be you and him.

Even if it means bringing you to the void too.

As for if you meet Gaster after the core incident? Well, the way doesn't matter, and what does is how he acts now.

Unlike before, he is more smug and calculated. It seems the void had given him some time to think, and he had used that time well.

Sure, he's a bit out of touch with certain things but he adapts quickly, and unlike before he doesn't hide his fascination with you. Rather it be infatuation or just a simple interest, it matters not.

He tries to spend every waking moment with you, but unlike before the core incident, sometimes he doesn't bother to do anything and just simply observes.

When caught, he'll say he just saw something for a moment or just some other poor excuse at first, but with time he will grow more shameless. It will go from implications of him looking at you to full on admitting it while sneaking in a little thing he noticed. Good or bad.

He is always around, and when you think you're alone he'll just seem to suddenly appear out of nowhere, never giving you a moment of piece.

His mannerisms now are more strange and unusual.

Gaster will talk about something only to stop for moments at a time before picking up somewhere else, like he had been talking the entire time he was silent.

He will go from switching from subject to subject, to trying to just stick to one singular topic. The switch can be so sudden and quick that it's hard to keep up, and Gaster himself is not only aware of this, but abuses it as well.

Through rants and conversations, he will sneak in little details that he decides to add just for 'fun'.

These details can range from small, minor things you do in your day to day life to things you only do in private by yourself.

Even if you do manage to catch it, Gaster is already on another topic, and he is quite the persuader.

Much like Sans, he will separate you from everyone you love, and will have you confide in him, but it is much more extreme.

Gaster, no matter which way you meet or when, will have you not only completely isolated from everyone you loved, but will make you hate them as much as he does, or at least dislike them to the furthest extent he can make it.

He will make you see the awful world he sees for you, and make you feel repulsed and disgusted by it. He will twist your mind and make you hate the world outside of him, and if he really does a good job, you might hate it as much as you fear it.

Everything you do, say, and think is all from Gaster. From the inside out he will 're-wire' your brain to his liking, and make you the most ideal person you can be. He will not only make you useful, but he will make you loyal and obedient to him.

You will be everything Gaster wanted, and Gaster will be everything you will and had ever wanted and needed in return.

Gaster will make your relationship, no matter the feelings shared, his perfect little experiment. One he is determined to see through.
