DOOM
Undyne can’t stop playing DOOM (2016) and wants to meet Doom-Guy in real life. And possibly in combat.
Anime is ambiguously real, but video games are based off history, right?

this is more of a hc for undyne than alphyne but still imagine this: since undyne doesn’t have a nose how about she has smell receptors in her mouth/on her tongue? on the surface alphys takes a sniff like ‘is someone cooking? smells like bbq’ undyne just sticks out her tongue and nods
blep
I couldn't think of a title
Alphys parents died during the war, same with undynes, but instead of being adopted straight away like Undyne was by gerson and Asgore, she was left on her own, living in the dump or with bratty and catty, but ultimately she was alone
She found the lab by accident, well she would tell you it was by accident, but that would be a lie, it was really because she had a intense love for science. It was there she met gaster. At first alphy went unnoticed by Gaster, watching him closely through the window of the lab for hours on end as he diddled around in his lab. Well eventually He did notice the little yellow Dino peaking at him through his window. But instead of being mad for the spying he began to train her as his assistant.
Gaster initially came off as a soft-spoken man, often preferring to keep to himself rather than socialize. He had been hired by Asgore, who was in need of a scientist whose research would help find ways to make monsters stronger, more resilient against humans, if they ever decided to attack them again, (much like Alphys was trying to do in the main game) but however, much like Alphys in the main game, the experiments all turned into failures and he was at his wits end trying to create the perfect weapon against humans.
Years passed, and despite repeated attempts, every experiment became a failure. Gaster explained to Alphys, that like many things In life, science is experimental at best and resulted in a large number of failures and false starts. Gaster himself also noted to her that, ever since the determination machine (what ever it was called I forgot) earned him his license, he had yet to present any scientific breakthrough worthy of his yearly assessment from the king and feared that a failure this year would cost him his certification and research privileges as well as his job. (But we all know asgore would never fire gaster he’s to nice for that)
Well one day while at the lab she began to notice that gaster began to act strange. he was more often engrossed with his work than anything else and rarely if ever left his lab for anything more then something to eat. It wasn’t until she heard the blood curdling scream from his behind his lab door that her scared curiosity got the better of her and she peaked through the keyhole.
Now being small she couldn’t see anything clearly, but could just barely make out a large Moving mass just beyond the door. She waited until he left to sneak in and what she saw frightened her. A large moaning groaning mass stared back at her.
Gaster…had made a Amalgamite.
She turned her head and noticed it wasn’t his first attempt. Across the room she could see more smaller masses moving back and forth making curious glances at the small yellow lizard. Gaster had been doing it for a while, unbeknownst to her.
Sickened by the fact she hadn’t noticed until then, she left and hid, wracked with guilt knowing that if she didn’t tell anyone more monsters would be hurt due to the inhuman practice, if she did however the one man who raised her face would face serious consequences for his actions and she would be alone again. Well eventually depression and guilt kept her quite long enough for her to go to the dump where she soon met Undyne who she took a great liken to, so much so to the point where they hung out everyday. But she never told her what Gaster did.
One day However. People began to notice, more monsters had begun to disappear, a thought that baffled most of the underground residents and horrified Alphy’s and on that night, filled with guilt she confronted Gaster about the amalgamates, pleading with him to stop the horrific experiments. But Gaster said no, the need to please and to keep his license more greater then his lack of morals despite the whole fact he’s hurting more monsters then he’s suppose to be helping.
On the day of his assessment, Asgore showed up to the lab tagged along with Undyne who just went as a excuse to take her mind off the fact she hasnt seen Alphys in days.
When asgore asks what progress he has made, Gaster points to a Amalgamate who is sitting in the corner of the room.
“Finally, he says, I’ve made a creature strong enough to withstand human attacks, and it obeys commands watch”
He stands up straight and in a booming voice says COME, which it does, slowly skittering its way across the floor hunched over. Asgore and Undyne stand there looking all impressed. He kneels down and says to say hi to their company.
The amalgamate opened and closed its mouth a few times, as if trying out its body. Gaster clenched his hands tightly, visibly nervous. This had to work. There was nothing he had done wrong. He tells it again to say hi to their company
It does, it repeats the words hi there five times.
Impressed, Undyne knelt down to pet the skittering Amalgamate amazed by the texture of the creature, soft and rough all at the same time. She smiled, as The amalgamate kept saying hi even as she petted it’s elongated snout, while Gaster and Asgore Talked.
Though she couldn’t shake the nagging feeling their was something oddly familiar about the amalgamate, it’s tone of voice…it sounded shy, sad even.
“Hi…th-ere…” the amalgamate said again, then again: “Hi th-ere.” The creatures face turns into a look of pain, its mouth opening more wide, showing off a familiar set of lizard like teeth. “Hi…th-ere…Hi…th-ere…Un-nie!” it says at last.
how long had Alphys been missing for again
Undynes eye widened, she looked at Gaster, Gaster looked at The Amalgamite, Asgore looked at them both as both he and Undyne put two and two together
Guess She did get to see Alphys that day
//you can make up your own ending, my ending ends with Asgore finding out about the experiments and throwing Gaster into the core and Undyne taking the amalgamate home, it isn’t really a headcanon, just a idea I had in my head that I wanted to share. You don’t have to post it up If you don’t wanna or if you feel it’s more Gastery then alphyney
You wanna get a idea of where I got this idea for here’s a clue Ed….ward. Big Brother…Ed
I’m not entirely sure if this goes here, but I feel like you all might appreciate it. Today, I asked my friend who can play a handful of Undertale tracks if she could do ‘She’s playing piano’, and we dug up a bunch of note sheets but none of them sounded quite right, then she switched to trying by ear, and finally she just frowned and went 'I … don’t think Undyne’s piano is tuned. It’s like these are notes that don’t really exist …’
So, basically, Undyne probably just found a piano at the dump, carried it home, and smashed the keys until she got something she liked and I think that’s beautiful
So, I’m just dropping bye (again), because a little idea popped into my mind… Summary: Undyne cut out her own eye. Apparently, something happens, and Undyne’s eye becomes infected. It’s some crazy, lethal thing, so she freaks, and out of fear, cuts out her own eye… (please, nobody steal my idea?? ;w;)

little mermaid au: undyne is a mermaid whos part of the royal guard but she doesnt long to be part of that world, she just wants a loving relationship. so king trident keeps matching her up with other mermen but theyre all scared of her because she could fuck them up in a heartbeat and she doesnt love them. so she meets alphys and they start hanging out and undyne starts to bring her gifts like seashells, etc. so undyne tells trident about her love and king trident accepts her but ursula is hella homophobic and curses undyne so that if she ever talks to or touches alphys undyne will become less of a mermaid each time which could have devestating effects. so she kisses alphys which turns alphys into a mermaid and removes undynes gills and her tail so they kiss again until alphys is halfway human and undyne is halfway mermaid and they live happily ever after.
It is I, the mystical Shark Anon, returning for more shitposts... but why shitpost when you coild sharkpost amirite

Hey, guys! Sorry for not updating this blog for a while. But I'm back now! Asks have been posted, and submissions are in the queue. Feel free to send in more headcanons!
Alphyne will have so many babies. Undyne will be called Ma or Mama, Alphys will be called Oka-san or Ka-chan. Because why not.
Alphys has synesthesia and really enjoys Undyne's voice, because it looks so nice for her and Undyne can listen to her for hours when she explains how it all looks.
this……. is beautiful omg

I'm all for Alphys being a lil flustered and inexperienced bab, but what If it was undyne was the inexperienced? think abt it. Undyne is probably to busy with training to even think abt kissing so what if Alphys had to guide her through EVERYTHING
HECK. YOU KNOW I’M ALL FOR THIS. INEXPERIENCED UNDYNE IS GOOD STUFF… ALPHYS. TAKE THIS OPPORTUNITY. AND USE IT
Undyne always had a natural talent for piano and was mostly self-taught, but being the aggressive warrior she is, her technique was rather...heavy-handed. Upon reaching the surface, she heard Claude Debussy's "Clair de Lune" and just desperately wanted to play it, but found that her technique made it almost impossible. After months of frustration, she finally sought piano lessons, corrected her technique, and has since played Clair de Lune every night for Alphys before retreating to bed.
oh my goodness yes. undyne turning her determination into results, especially for something as sweet as this… good stuff
Imagine if Undyne didn't talk to Alphys when she found her by the caverns edge, imagine if she decided to give her personal space to work out her issues. Imagine hearing a few days later that Asgore can't find his royal scientist. Imagine her horrified as she races back to the cavern edge and in horror find Alphys dead down below after she hit a rock, imagine her guilt in knowing She could have prevent this but didn't and she blames herself for noting her contemplative look but not doing anythin
aaaaaaaAAAAAAAAAAH WHY YOU GOTTA LET THE LIZARD AND THE FISH GET HURT. NO
I totally headcanon that on the surface, Frisk starts to get everyone into modern human things, like memes, fandoms, customs, etc. and one that Alphys and Undyne really love is the concept of trick-or-treating on Halloween. So every year, they take Frisk around the neighborhood (dressed up as well, of course). And after a while (with MTT's help), Alphys starts making elaborate cosplays for her and Undyne. (Once they even go as Sharkboy and Lavagirl; Frisk got them both really into that movie.)
omfg yes… alphyne Halloween and cosplay stuff is SO GOOD
Undyne says that she's used to people freaking out because she's scary, right? So, what if she's been that way since she was a kid, and other monsters didn't really want to be friends with her because of how extreme she was? Aside from Gerson and Asgore, of course.
oh man…. lonely kid undyne is really sad tho gosh
just… her first constructive social interactions would be with gerson and asgore :( damn

Undyne, Alphys, and Mettaton on and anime marathon, it gets to hour 34 and Mettaton ran out of battery unnoticed since Alphys couldn't hear him when he said he couldn't find his cable and Undyne passed out hour 29.
alphys enthusiastically watching anime while her gf and bff are unconscious is accurate as hell ahahahh
Imagine Undyne and alphys going shopping and they split up to find the stuff and while ALPHYS is getting the noodles or whatever some jerks start making fun of her and she's just trying to ignore it but they won't stop they won't they won't and then the lead jerk feels a tap on their shoulder and they turn around and all the color drains out of their face bc there she is. fish gf here to save the day with her spear and terrifying smile.
undyne bout to FUCK EM UP
alphys probably tries to drag her away halfheartedly but undyne is having none of it she’s KICKING THESE ASSES
