Shipwrecked by Withstarryeyes

Summary: When he wakes there is a man above him. He’s backlit by the sun, features blurred out by too much light, and Bakugou shifts upwards abruptly. The man slinks back, but lingers, hands outstretched as if he’s afraid of what Bakugou might do. In the background, waves crash onto the sand, and Bakugou turns, searching for his ship, for his crew. He screws his eyes shut, breathing quickening as he remembers the storm and the feeling of the deck on the waves. Something cool connects with his cheek and Bakugou opens his eyes, scrambling backward without thinking.

Home is where the waves crash by tiredwrites

Summary: Izuku thrashes in his cage, the fins that line his large tail flare with a dangerous purpose. The claws his fingers taper into slice through the water and catch the light that filters into the clear water of the aquarium tank he's in.

His gills flare in irritation as he flips around, muscled tail ramming into the three-inch glass barrier with a thundering BAM!

Bioluminescent sacs under clear scales flare and glow, flashing a brilliant toxic green. The team that had brought the merman into the tank watch the mer flail and roar, flexing the powerful jaws that can often unhinge, like a snake.

Sand is Land and Sea Inbetween by Frost_or_Fire

Summary: Katsuki is by no means a marine biologist, really, and he knows that he could just walk away and act like he saw nothing. Act as if he didn’t see a half-human body laid across the late October sand while a black tail is still in the water, sorta concealed by the rolling waves that washed over the figure. He could just act like this is all just some dream that his subconscious cooked up for him to be put through to show how miserable he actually is.

But Katsuki fucking Bakugou is anything but a coward and a sick person.

Bakugou finds a Merperson on a beach and takes them home to help with their injuries, and possibly get more than he bargains for.

Save to Swim by sanjusangendo333

Summary: Izuku is out for a run, when he spots a blond man in distress in the river. He quickly strips off his shoes and clothes until he's barenaked to save him. But Katsuki is not in distress and nor is he a regular guy. He's one of the men from the elite diving unit of Japan’s coast guard who is in the middle of diving exercise.

Katsuki and his unit all agree that, ‘WOW! Izuku can swim really well and so fast!’ He'll really fit well in Katsuki's diving unit, they all say as Izuku is still in the water. But Izuku hurriedly excuses himself and swims away, because otherwise, they'll see the fish tail that his legs transformed into the moment he dived into the water.

Katsuki, of course, does NOT give up on trying to recruit him.

[azzo0]

Katsuki cried the first time he held his newborn daughter in his arms. His eyes watered when the nurses guided his hand under her head and adjusted her on his arm. He trembled as he brought her closer to him. He held her closed fist in his hand, amazed by how small her hand was compared to his. Little fingers curled around his index, and he wondered how something this unbelievably tiny could manage to grip his heart so tight in a matter of seconds. He sat on the chair behind him, holding his baby girl close to his chest and covered his eyes with a hand, bursting into tears.

Pairings: King Merman! Bakugou x Human! Fem! Reader

Word Count: 5.2k

Warnings: Just fluff.

Summary: You meet a merman one day and find yourself with your very own trading companion. You exchange gifts of the land and sea. The two of you were fine until Katsuki says he wants more from you.

𝐅𝐈𝐂 𝐌𝐀𝐒𝐓𝐄𝐑𝐋𝐈𝐒𝐓

Katsuki Bakugou gets everything he wants. The underwater kingdom is his, and whenever he wants or needs something, with a flick of his webbed hands, it appears. He is worshipped and maybe even feared by all of the seas. King Bakugou, the warrior ruler of the sea.

Except for a mate. No matter how many mers, both male and female, his court presents him with, he never feels anything toward them. His mother scolds him for not even meeting the young candidates, but he doesn’t give a shit. He gets what he wants; he will know if they are worthy just by a single glance.

So on some days, he forces his mother to watch the throne while he swims and swims just to clear his mind. He picks fights here and there with other sea creatures just to test his strengths. After he wins his battle against his third great white, he realizes he needs something stronger. Something to really pique his interest.

A human. Well, from afar, they look pathetic with their gangly limbs, but it is common knowledge to a mer that they possess weapons that can easily kill any creature of the sea. But this is Katsuki Bakugou we are talking about here. He isnt just some mer. He is the most powerful being of the sea. No one, including a human, could beat him. 

So, the arrogant bastard took toward the surface to find the closest human. The water becomes more shallow, and not that he would ever admit it, but adrenaline fills his veins when he gets closer and closer to the shore. 

Luckily for him though, a human was close. In the water, too. He was dreading trying to coax one into the ocean. Katsuki snickers at the strange limbs called legs kicking to try to keep the human afloat. It was so embarrassing for them. One flap of his tail, and he is yards ahead of them. It was incomparable the strength between the two species. 

Without much hesitation, he grabs the submerged legs and pulls. They scream, of course, when they lose their precious oxygen and are surrounded completely by salt water. Their arms flail, and their legs continue to fight their way to the surface, but it’s all in vain. After all, this is Katsuki’s element.

Wanting to get one glance at the human before making a swift and easy death, he turns the figure around, and his eyes widen.

You were pretty. Prettier than any of the other mers he has ever seen. Even if your face is contorted in fear, he takes a second to admire your hair, eyes, and lips. They were all so cute. Exactly the way he likes them.

And your strength was actually impressive. Although you were no match for the king, you were definitely putting up some sort of a fight. He actually had to grip you tighter so you wouldn’t squirm away. Both of you knew it was a losing battle, but still, you really tried. You definitely had survival instincts.

As Katsuki gets distracted admiring the creature, you get one lucky hit and manage to kick him right in the nose. He hisses out and lets you go. 

He could go out and grab you again easily but didn’t feel the need to. After that fight you put up, you deserved to stay alive. Stay alive, so Katsuki can meet you again.

You were just trying to take a dip in the ocean, really. After all the stress you have had this week, you deserved it. A nice relaxing day by the beach. You were not planning on almost getting drowned.

You swim swiftly toward the dock and yank yourself up before the creature tries to grab you again. You didn’t see much except for flashes of blonde hair, red eyes, and an orange tail. What was that thing? Some sort of fish? It just didn’t make sense. What fish could pull you down into the water? The beach was completely private, so it’s not like you could tell a lifeguard what happened.

You shiver and grab your towel before heading inside your beach house. You began to ponder, desperately trying to figure out what the strange animal was. After about an hour of research, you came to the decision that it was definitely a mermaid. Many studies have shown that they do, in fact, exist but are extremely rare to find.

It seems absolutely insane to you, but what else could be able to hold onto you like that? And that tail…It was huge. 

You aren’t going to go near the beach for a while. Even so, though, you really did want another glance…I mean, seeing a real-life mermaid is crazy! Once little peep of the mermaid surely wouldn’t be a problem.

After all, curiosity killed the cat, but satisfaction brought it back.

Three weeks. Katsuki has managed to escape his royal duties to see your ass, and not once have you come back even close to the water. He has scouted the area over thirty times and found the small shack you call home. The mer lets out a scoff as he watches your shadow move back and forth inside the building.

He has thought about throwing something at the building but thought against it. He didn’t want you to think he was a violent maniac (even if he was) with your first real meeting. So, he boredly swam back and forth, waiting for you to come outside again.

He was in luck because at around 5 pm, you did finally open the door of your shitty shack and step outside. He quickly dove into the water to watch from below the surface. The last thing that he needed was to scare you back into hiding. 

His eyes follow your figure as you walk toward and onto the dock that bridges into the ocean. You look nervous but determined, and Katsuki can see you holding something but can’t determine what it is. 

Suddenly, your loud voice calls, “Hello!” over and into the water. You flush in embarrassment for doing something so silly. But you continue anyways, “If you are out there, mermaid, come over here!” It probably wasn’t the most convincing way to lead the visitor over, but whatever, you were desperate.

Katsuki smirks in triumph. He only knows very little of the human language due to his studies as a child. All he knows is that you greeted him and said the word “mer,” so you must be calling for him.

So he pops his head out of the water with a small smirk on his face. His orange ear fins are spread wide and on display. His scarred tail, from all the fights he has won, beats against the water as he watches you. He gently displays his sharp canines with his smirk. Like always, he looks like the strongest being of the sea. 

When you take in his appearance, you scream and fall onto your butt.

Katsuki lets out a light bark in laughter, watching you fall. He couldn’t blame you; those strange limbs looked hard to use. If he were human, he definitely wouldn’t struggle, but he bets Denki or Eijiro would. 

He puffs out his chest and made himself look as large and powerful as he could in the water. “Hello, I am King Explosion Murder or King Bakugou, ruler of the undersea.” He stood there waiting for the excitement or shock that usually comes from hearing his title, but nothing came. “Ruler of the undersea. Did you not hear me extra?” Judging from your frightened appearance, trembling on the doc, no, you did not understand. 

And then he remembered. Of course, you don’t understand. He isn’t speaking in your tongue. To you, it must have sounded like a bunch of trills and clicks.

Katsuki opens his mouth to speak but growls. He doesn’t remember how to speak your language. It’s unnatural for mers to do it, but nobility are taught it, just in case. However, that was when he was ten, and he hasn’t practiced since.

Upon hearing his frustrated growl, you point your knife straight at him and threaten him. “S-Stay back! I have a knife, and I know how to use it!” You didn’t, but that was beside the point. You shouldn’t have come out here. It was a stupid idea. Curiosity did kill the cat, and you’ll need more than satisfaction to get you out of this situation.

The blonde doesn’t understand any of your words. The only thing he understands is that you are holding out a knife toward him. A gift! Already? Katsuki is known to be bold, but here you are, offering a courting gift on day one. I mean, it made sense, considering his physique. You must have seen how powerful he is and were quick to pounce. Eager, he likes it, and he can’t really blame you.

He huffs out pride and lets out a click in thank you. Then, quicker than lightning, the blonde snatches the knife from your hands and into his. He holds it up to admire it, unaware that you’re currently freaking out without your weapon to defend yourself. He scoffs at it. It was sharp but not even close to his very own canines. He turns toward you and pulls the knife up next to his teeth to show the comparison. He is once again unaware of how you pale drastically.

“Stay.” He uselessly commands before diving down back into the water, knife still in hand. You cock your head to the side in confusion at his disappearance, but realizing this is your only time to escape, you begin to book it down the dock and toward your home. 

You don’t get very far. Katsuki, effortlessly fast, grabs your foot before you can return to the sand. You stumble forward and land on your knees, causing you to hiss in pain. A small scrape forms on your left knee.

He huffs in annoyance. “I said stay, you idiot! Look what you did!” 

The loud growls cause you to tear up. This is it, isn’t it? He has got to be growling so much  because his prey got away. It was a stupid idea, all of it. You were going to die, and nobody was going to find your body and–

Katsuki grabs your leg and licks the wound on your knee like he has done countless times with others during battles. After all, mer saliva has healing properties. Then as your eyes widen in shock, Katsuki pushes an orange sea shell toward you. He set in the water, just earlier for you. He lets out an annoyed bark when you don’t reach for it, and hearing the warning, you quickly scramble to take it. The blonde smirks in triumph and continues back to healing you.

You shiver when you feel the tongue back on your knee. It was like a cat’s tongue. The prickles gently nick at you. But, with all the courage you can muster, you tear your gaze away from the creature and onto the sea shell. It was light orange, and absolutely massive. Seriously, it was about the size of your whole hand. But, it was pretty and shiny in the sunlight. 

You spare a glance at the blond, who is still completely focused on the task at hand. You could guess that he is trying to heal you for some odd reason. It made your heartbeat begin to return back to normal. Why would he heal his prey from such a minor wound if he was going to kill anyways? But why would he want you alive?

Then, you look to the right of him and see that in his hand, he is still holding the knife. Your eyes widen in realization of what is happening. “Trade! You want to exchange items with me. From the…human world?” The mer tears his mouth away from your skin and furrows his eyebrows in confusion. You point to the knife and then the seashell. “Trade?” You explain.

Katsukis eyes widen in understatement. So, the human word for “courting” is “trade”! Only a genius like himself would be able to figure that out so quickly. He lets out a soft grumble and nods his head. Then, realizing if this relationship is going to work, Katsuki has to tries to try and speak in your tongue. “Chr–aye-dd”

Your mouth falls open at the attempt of your language. The whole thing was absolutely insane, and now the strange creature is trying to communicate with you. This is a once-in-a-lifetime experience, so you continue speaking. “Yes, Trade! But say “Trr” instead of “Chr” You enunciate the sounds, so he understands.

Katsuki grumbles stubbornly when you correct him. Only his mother has been one to nag in, nobody else has the guts to do it, but here you are correcting him within the first greetings. You were bold; he had to give it to you. He also likes that. So, for your sake, he tries again.“Trrr-aye-d”

You laugh at this and smile gently. “Yes! Thats it! Trade.” You once again point to the knife and the seashell. 

Seeing you smile, Katsuki lets out a trill and nods. Without much permission, the blonde rests his head on your leg, careful not to touch the wound. Then the hopeless mer begins to daydream. This was going perfectly! Not even one day of knowing him, and you have already allowed him to court you. Now, it was smooth sailing from here. He just needs to bring you a couple more gifts, and finally, King Bakugou will have his very own mate! 

You, on the other hand, are freaking out a little bit. A merman is here and resting his head on your legs! Nobody would ever believe this was happening. 

You tear your gaze away from him for a second and notice that the sun is almost down. Although the mer seems friendly as of now, you didn’t feel comfortable with him enough to stay with him during the dark. So, you try to gently get it up without disturbing him too much.

His daydream comes to an abrupt stop when you begin to move your legs. He groans in annoyance. “Stop.” He commands, which comes out in a small bark. You ignore him, considering you can’t understand him, and Katsuki slides back into the water. 

He lets out a low growl, and your eyes widen. He wasn’t having second thoughts about this little exchange, right? So as you get to your feet, you quickly say, “Tomorrow, I will come back, and we can trade again. Okay?”

Katsuki looks scepitical. He only got out the word tomorrow and trade. Which definitely is a good sign, but does he trust you enough to keep your word? If he has to wait another three weeks, he is going to absolutely pissed. But then again, you seem to like him a lot if you already began wanting to court him on the first day of the meeting. Plus, you allowed him to touch you, once again, another good sign. You have got to like him.

So he sighs and trills a goodbye before swimming back down into the deep blue sea.

Katsuki Bakugou was adorable. It’s been about a week since you have known him and you have visited him every morning. He seems to be rather attached to you already. One day, you overslept and missed his meeting, and the next day you got an earful of mostly growls and barks. You thought it was adorable that your new friend missed you.

Currently, it was Friday, and exactly a week since you guys have been talking to one another. You learned his name and even have gotten him to speak in small sentences. He seems to pick up the human language very quickly. You wonder if it was a mer thing or a Katsuki thing.  Either way, you praise him immensely, and he acts like he doesn’t care, but its obvious by the red ting on his cheeks he does. He also teaches you the language of merfolk. Your vocal cords don’t really do the barks or clicks justice, so the two of you continue to speak in your language.

Not only that, but the mer was heavily physically affectionate. It was hilarious, considering the fact that he would insult you on being a “weak human,” and then the next minute, would curl into your lap as if nothing had happened. 

In all honesty, no matter how much of a brat the mer was, it has been one of the best weeks of your life.

“Human. Att–tention. Now.” The orange merman demands when you stop running your fingers through his soft blonde hair and stare off into the distance. You chuckle at this and continue to pet him. You are glad you taught him the word “attention” because before that when he needed it, he would take to softly biting you. You have small bite marks all over your leg because of the overgrown, needy creature.

A small, content smile falls on his face as he nuzzles into your legs. Courting has gone absolutely perfectly. You were gentle and warm but were able to put up with his shit. A perfect match the two of you are. 

Of course, every once in a while, you do say some stupid things. “Katsuki, do you think I can meet some of your mer friends?” The merman looks up at you and gives you a familiar glare. You smile in return, hoping to encourage him. 

It doesn’t seem to work because he lets out a cat-like yawn and closes his eyes again. “Friends, weak. Stupid,” He grumbles, and you roll your eyes.

“I bet we would get along considering you call me weak and stupid,” You remind, and Katsuki opens his eyes back again to glare at you.

He lets out a series of trills and clicks on accident before sighing and switching back to your language. “On–ly need me,” He challenges, and you give up the argument. Katsuki was as stubborn as a mule. If he didn’t want you to meet his friends, you won’t.

All of the sudden, Katsuki rolls off your legs and into the water. You tilt your head to the side, but the mer just grumbles out a, “stay.” and lightly bites your calf to get his point across. You, like always, flinch at the bite, but let him, knowing that denying him makes him even more upset. Besides, it’s probably a sign of affection.

Then, he dives back into the water, leaving you alone. A couple of minutes go by, and eventually, he pops his head back above the water. He raises his webbed hand and shows a squirming fish in his hands. You give him a questioning stare, but before you can ask, he plunges his sharp canines into the body. The fish dies immediately, and you’re left in shock at what the hell just happened.

He then offers the fish to you. “Eat,” He barks, and you shake your head, disgusted by the fish placed so close to you. Katsuki doesn’t like this answer, and he glowers at you. “Food. Eat. Hun–ted for you.”

Even if you are used to his demands, you are not willing to go that far for the sea creature. “That will make me sick, Kats. I can’t eat raw fish, but I really appreciate the offer.” Katsuki stares at you for a second and then, like usual, lets out a series of annoyed trills. He grabs the fish and quickly begins devouring it, bones and all, much to your horror. 

Once finishes, he looks back up at you with a satisfied smirk. “Good Hun–ter.”

You nod in agreement, “Yes, you are a fantastic hunter Katsuki, way better than me.” He chirps and nods, preening at the statement. You roll your eyes and laugh at his behavior. 

And then he sighs and, like usual, begins his goodbyes. He seems to be a very busy creature, only being able to meet for about two hours a day. You wonder what is taking up his time. Another mer? Maybe he has a family? But he never mentioned either of these things.

You don’t get time to ponder on it, because Katsuki rubs against your legs one last time before saying his usual statement. “Trade. To–mor–ow”. To which you nod and wave your goodbye with your new pink seashell that you add to your collection.

He nods before falling under the water and disappearing.

You begin to think more and more about Katsuki. Even if he was another species, you couldn’t help but be attracted to him. His muscular upper body, his soft blond hair, his piercing red eyes, and even if you hated the canines in the beginning, they are beginning to grow on you. Plus, he has the best personality. Although it is a little aggressive at some points, you know he has good intentions. 

He is sweet to you, under all of the insults, and is exactly your type (well, if he was human). So, like a normal person of your age, you begin to daydream what it would be like, to be more than a trading partner with the strange, but enthralling creature.

It’s been about three weeks, and the two of you have been “trading” almost every single day. Things like forks, coins, small mirrors, and cups have been given away while you receive an abundance of seashells and old jewelry that has fallen into the sea. Katsuki goes out of his way to find the nicest items he can. After all, he is a king, and his mate deserves only the best.

Katsuki knew he was doing a perfect job courting you. You are happy with him, he provides for you semi-well (only because you won’t take his food), and he is a fantastic protector. Often times the red-headed shark tried to talk to you, but Katsuki manages to scare his friend away every time. He isn’t going to risk you falling for some other extra. You were way too eager to court with him (even if it did make sense considering his physical appearance), and he didn’t want to play the odds of you accepting some idiots advances. You were his, and he was yours. That’s how things are supposed to go. So, today is the day he was going to ask you to be his mate. Then, the two of you are going live happily ever after.

He leaves his mother on the throne, like always, and grabs the ring he has planned to use. It was gold, and he removed the previous gemstone and replaced it with a pearl he had found when scouting the area for any threats. He knows that rings are weirdly important to humans, so, it was probably a good idea to get one. Then, he heads to your guys’ meeting spot.

You were waiting at the dock with your feet in the water. He swims up to you and lightly traces his hand up the bottom half of your leg. Then, like usual, he lays his head on your legs. You smile and pet his hair, “Hey, Katsuki.” He lets out a small click in greeting.

“I brought you something,” You continue, and Katsuki’s ruby eyes look up at you, slightly intrigued. You always gift him the strangest things. You pull out a tennis ball, and Katsuki squints at it before snatching it from your hands. He then begins to assess it. He rubs his cheek on it, then bites it gently, and finally growls at it, just to make sure it wasn’t anything dangerous. Once completely satisfied that it was safe, he trills in thanks. In your broken language, he says, “Good gift. M–Mine better.” to which you chuckle and nod, not willing to argue with the guy.

He pulls away from your legs and back into the water. A second goes by, and he is back up above the water and smirking as confident as ever. Katsuki quickly reminds himself of the stupid human customs he is trying to follow. He has practiced this sentence about a billion times. He forcefully, and a little nervously, thrusts the gold ring into your hold. “I K-King Katsuki Bakugou, take you, Y/N L/N to be” He lets out a small growl in frustration when he forgets how to pronounce the last part correctly. “To be…my mate.” He puffs his chest out while he waits for the tears and your acceptance.

But much to his surprise, you begin to giggle as you grab the pretty ring. You admire it and praise him on how beautiful it was. You have never seen a ring like this, it was pretty. You place it on your pointer finger and smile. Then you pat his head lightly and say, “Yes that is how wedding ceremonies go! How did you learn those lines? And I love the addition of “king.” Great touch Kats. Actually, did you know that I happen to be the Queen of the human lands?”

Katsuki has never been more confused in his life. Firstly, you put the ring on the wrong finger. He read so many slabs that told him that you were supposed to place it on the one next to the pinky! Secondly, you didn’t even respond to the declaration. You just praised him on his abilities. Thirdly, you are a queen?! Would this mean that your two people can finally live in peace? This seems like the most important question, so he says, “You–Queen?”

You laugh once again and, this time, shake your head. “No. Sorry I was just teasing you, Katsuki. I couldnt help it since you said you were the “king” of the sea.” He furrows his brows. Did you think he was joking? He has left his people abandoned for you daily, and you don’t even believe him!

“I am King! You are my Q-Queen! Mate!” His newly learned language gets choppy when upset. He grabs onto the doc with his hands and looks up at you with a scowl.

You tilt your head to the side. “Mate?” 

Poor Katsuki goes into another hissy fit. He growls and grumbles, and you furrow your eyebrows, used to his dramatics. You don’t know exactly what’s pissing him off, though. 

You are pissing him off. You guys have been “trading” for two weeks now, and you don’t even know what mates are. What do you think these entire interactions have been about? “We trade. Now we mate.”

“Like animals do?”

He uses his tail to propel him above the water. Now he is almost your height when you are sitting down on the dock. He only does this when he really needs your attention. The scowl has deepened, and this time, you do flinch. “Like mer do!”

Was Katsuki joking? About the king and the mating thing? You have never heard him joke before, but also, what was he talking about? You guys originally were trading items, and now you guys are friends. Did you confuse him somehow?

Your thoughts were suddenly cut off when Katsuki leans forward and pressed his lips onto yours. They are wet and a little salty, but still soft. You are just glad that you can’t taste fish on his lips. Your eyes widen for a second, but then gently kiss back for a second, and Katsuki pulls away. Red tints his face, and you probably match his furious blush. “S-See! Mate.”

Oh. So this entire time, he has been wanting to get with you? You use your hands to cover your face in embarrassment, but Katsuki is quick to remove them with a short but scolding bark. “We trade. Now we mate.” He repeats.

You realized that you confused him this entire time. He misunderstood your definition of trade. “You court and then mate. Not trade Katsuki. Trade is when you exchange items, like merchants do.” 

Katsukis face contorts into disgust. Like the lower-class people? He is a king, for christ’s sake! How did you think that he was trading with you like some lowly extra? He didn’t need your useless items (yes, he did, he actually loves them all)! He lets out a series of growls and barks in the mer language at your misunderstanding. Finally, he, in your tongue, says, “Stupid human!” 

Although you haven’t known Katsuki for that long, you know is not mad specifically at you, just upset. I mean rightfully so; you have misunderstood his attentions this entire time. You have got to make it up to him. So, you lean over and tilt his chin upward toward you and cut off his growls with a soft kiss. He, of course, shuts up and kisses you back intensely. 

He hates craning his neck to kiss you, it makes him feel small, and he is the strongest creature under the water; he should never feel small. So without much hesitation, he grabs onto your figure and pulls you into the water. 

You screech in surprise as the cold water hits you, and Katsuki grins. He presses his lips against yours again and effortlessly holds you above the water. Eventually, you pull away with a trail of salty saliva. “You are going to have to recourt me.”

Katsuki frowns as his face fins pin straight back on his face. “Why?” 

“Because I didnt know you were trying to courting me. I want to enjoy it this time,” You hum, and Katsuki flicks a tad bit of water into your face. You scrunch your face up and whine, and Katsuki laughs low.

His orange tail flicks into the water. “Idiot human.” But, he still nods in agreement. It wasn’t like he was going to force you to be his mate. If needed to be, he can wait.

Your smile turns mischievous. “And you have to court me like a human does.” This time Katsuki does growl in annoyance. Human ways are so tedious.

“No.”

“Awe I guess I just got to find a human “mate” to court me….” You fake pout, and Katsuki grips you tighter. He can see right through your bluff, but pissing you off right now in such a nice moment does not seem like the best idea.

“Fine.” You give him a peck on the lips for his compromise. He in return, grabs your hand and replaces moves the ring from your pointer onto your ring finger. He lets out a satisfied click with the new placement. Now both mer and human will know you are his.

As you watch Katsukis ministrations, you think back to what he said earlier and hum in thought. “Hmm and Kats you were just  joking about being a king right?”

Katsuki laughs mischievously and a little arrogantly. Your eyes widen at the response. “Right, Kats?”

“Nope.”

You squirm in his hold, but he wraps his tail around you, preventing you from leaving. “I can't be the ruler of a kingdom that I’m not even from! Plus I'm not even a mermaid!”

But Katsuki was already lost in thought, daydreaming once again of the future. Besides, there are many ways to get you changed into a mer, it wasn’t hard. “King and Queen Ex-plo-sion Murder. The most powerful mates of the sea.”

“Katsuki!”

[aimportantdragoncollector]

Kinda wanna know how the humans are space orcs story would’ve gone down if bakugo was with izuku when he went to the market. AU of the AU lmao

Ooo this is interesting! I consulted with my coauthor Zyla SweetBean to answer this question. There is a good route and a bad route.

In the good route, since Izuku and Katsuki go to the market together way back in chapter one, only one of them gets poisoned (probably Izuku). Since Katsuki is awake and pissed, he can fight off anyone who tries to take Izuku. Troops are called in to deal with the two violent humans who took a space station hostage. All Might and Yuuei get involved. All for One later shows up looking for a pet human. It's madness and pandemonium. Fortunately All Might gets the two boys away before All for One can grab them. They need to be enrolled as students at Yuuei because it's the only place they have sanctuary from the Federation. It's a good ending except for AFO's potential abduction attempts.

In the bad route, both boys get knocked out by the poisonous fruit and captured by pet dealers. The big problem: All for One only wants one pet. Izuku has green eyes like Yoichi, and Katsuki's spiky hair reminds All for One of a certain brother thief. Even in a science fiction AU, All for One always has a grudge against the spikes. So All for One sends Katsuki straight to Dr. Garaki's laboratory as a test subject.

Izuku gets to be the coddled pet (well, coddled by All for One standards) and never goes near the laboratory while Katsuki bears all the tests. Also All for One makes it very clear to Izuku, without even needing a translator, that Katsuki is a hostage and will pay the price for Izuku's escape attempts.

Fortunately, Aizawa finds Katsuki and escapes with him. This was barely in time because All for One gave Dr. Garaki permission to dissect Katsuki when they were done taking samples. They are once again forced to leave without Izuku but plan to come back for him.

On the plus side, this AU has a team-up between feral Inko and Mitsuki. They are an unstoppable force of destruction. Masaru comes along but just to hold their coats. All Might and Masaru bond over being terrified and impressed. All for One dies after the moms rip him to shreds.

Both boys have a lot more trauma in this AU. The doctor was even more sadistic with Katsuki due to All for One not holding him back, and Izuku is suffering from massive guilt about being the "lucky" one. The first day of school would be rougher, with Katsuki scared of aliens but he manifests fear as anger. Izuku is protective over Katsuki even when he's being a jerk, and that just makes Katsuki angrier.

However I have faith in Class 1-A's ability to once again break through to the angry pomeranian.

A hug for the y/ns?

You may be a fucking idiot, but I'm not going to fucking deny you something that is scientifically fucking essential for the human health!

Come here dumbass!

*crushes you in a slightly awkward but endearing hug*

□□□□

You and Bakugou:

[thebnha-auhoard]

Izuku: Self care is stuff like taking a bubble bath or putting on a lot of make up if you like that, or taking a nice warm nap and stuff like that basically.

Katsuki: Self care is the burning heat when rage washes over you. self care is when you feel the bones crack under your powerful fists. self care is the fear in your enemies eyes.

Todoroki : Self care is stealing someones birthday cake just to eat the frosting.

Katsuki: If you touch my birthday cake I’ll make you eat your hands.

[malificarscum]

Not to be a hater but what the actual fuck is going on in BNHA? I read until about half way through the war arc and I'm sitting here like?? Y'all still fighting for hero society and nor dismantling institutions of oppression? WHACK. y'all still sucking endeavors dick after he abused his family so badly one of them becomes an murderous villian? W H A CCK!

NOMU ! Katsuki Bakugo headcanons — ORIGIN

It' s not that detailed bc hard lol so any whump-related things , character death and torture have been only mentioned they are not descriptive . Also this au does not exactly follow through the original plot of the anime . It' s an alternative plot for it to fit and does not end up with the animes ending bc neo has yet to finish it lol .

Not proof read ! Bear with ne that there might be grammar errors , ne is not a native speaker ;) .

Characters — [ Katsuki Bakugo | Raid team mention | LOV. Mention | Dr. Kuydai mention | AFO mention ]

Genre — [ Hurt / no comfort ]

CW — [ Whump | muzzle mention | Defiant whumpee type | human to nonhuman ( by being nomued ) | Temporal character death | ressuraction mention | lab whump | Alternative AFO way | Alternative plot | Amnesia | fighting | inhumane testing mention | death mention | passing out ]

DNI - Fudanashis/fujodashis, women & fem-aligned, profic/proship, anti - LGBTQ+ folk & exclusionists, anti-antis, Necro- Zoo- Pedophiles + (NO)Maps(and other terms), basic DNI criteria, kink/nude/nsfw/sh/vent/pro-ana/ed/18+ blogs

So when Kat got kidnapped the heroes or the students couldn't rescue him. Instead he was accidentally killed during the raid because of trying to fight the villains and getting in front of a attacking hero. He bled out pretty much during the Kamino incident and when the LOV. Ended where they ended he was beyond recovering state.

Due to the potential and powerful quirk that Katsuki possesses as a villain and an asset he was instead brought to the lab. Now since AFO has been defeated, i think there could be a more artificial version of doing what he could. Like thinking more sci-fi type shit with a way of securing stolen quirks into something and then being able to give them as if they fuse into the body, bloodstream, DNA and mind.

But it's a lot more painful since it takes a lot of time and the character would need to be alive for it bc research. Also bc they want to make sure that he actually lives, even if it's barely so to see how it changes him.

Personally don't really like the do them like Kurogiri was done type of nomu when it comes to Nomu AUs lol so doing something different.

I think they could have someone with a revival quirk revive katsuki to a state he'd be alive enough to take care for a few weeks. So he just doesn't recollapse and die during the 'operation ' of exposing new quirks to his weak body. ( They still keep him weak and with quirk dampening collar bc they don't want him to try an escape any way possible lol. )

During the meek recovery time they give him which he is in agony and barely councious. The doctor, Kyudai, decides upon what he wishes to experiment with. Instead of going straight with how Kurogiri was made he ends up trying something more animalistic and shapeshifty, feral type ( iykyk ) even.

Having picked out the quirks from the storage of quirks he has to work with. It's been about three weeks and Kats still in pain but doing so much better than before at least. They've been starting the preparation of the operation already and he has no idea what's exactly going on.

So the only minus would be that he's stuck in a hospital bed, like literally restrained against it bc every now and then when staff came to check on him he would unapologetically trash around and try to attack them so they had to sedate him and made him rather delirious. They even muzzled him as well bc the man is loud and i mean L O U D even if heavily sedated.

He's most likely going to fight them every change and energy surge he gets even if sedated, he's stubborn and knows what's going on is very wrong even if he has no clue what's going on. So defiant smh giving the staff such a hard time /j .

Let's say bc of his fighting the staff he almost made his way to the skies again. His state was corrected tho, so the operation they had prepared him to undergo was successfull.

He was then caged up and locked away for four months before anything really happened. They monitored his state which was format for full two months. He kinda just fell into a coma for a sec.

But forcing him out if it with electric shocks as a experiment was successful. He awoke in pain and the first thing they got out of him was a blood curling scream of agony. His whole body welt like it was on fire and it went on for the rest of two months

His skin went from it's original colour to ashy black and had a weird soft leathery texture to it. His form changed to resemble a four legged snake, like an oriental dragon but not quite like it, with a black mane of dark cherry black hair with blond tips. ( Probs gonna end up drawing something resembling him lol )

His eyes went towards a orangish cherry tint and seemed rather flowy whispy-like like Kurogiris but more whispy.

His size if standing on his hind legs without tail would most likely be around 8'3-8'6 and with tail depending on the without tail measurements around 8'9-9'3 . Why I'm doing it this way ? Most likely because i wanna know how much he grows from first to 'final ' form. Aka when he grew first after the procedure and what he ended up being after settling in the new body. Y'know what I mean, right ?

After waking up it's more than evident that he has little to no idea who he had been before. Just waking up with amnesia and rolling with the pain and everything that most likely ended up with him being overstimulated and throwing a tantrum with bodies flying lol.

The quirks decided upon him were dragon , Shrink shift, Combust and his own original explosion quirk.

The Dragon obviously giving him dragonic form , shrink shift is about ones personal size shrinking and combust alight his mane and blood into a deep cherry red fire but not exactly to a explosive extention. And ofc his own explosions are just that explosions through his sweat ( although his quirk won't work properly bc he doesn't sweat anymore, but an alternative to that will be spoken later )

Testing is a pain in the ass and nursing everything together for him to be healed properly for it was even more. Live testing in which it was recorded for research with scientists + doctors present and having him test his abilities and new body finding and hitting the hard limits multiple times in a row.

It was basically torture for Kat. Since he had no recovery time in-between the testing and when got the time he was slow at it.

What they discovered was that from the dragon quirk the healing factory would only activate when he was on fire , but he had no resistance to his own fire which would end up hurting him more.

Just because the combust quirk worked it was risky to use, so with another add on he got a quirk that enchanted his recovery time and healing factory work giving him some but not much resistance towards the fire that the combustion quirk gave him.

Most of the quirks either malfunctioned together or gave him little to no resistance to the drawback of another quirk. Or it just ended up being really problematic quirk combo that was not suitable to be combined.

It was a shit show of upgrade and downgrade how the quirks worked and slowly Kat was becoming the most disasterous nomu they had ever created. He never lost his temper and was wildly unpredictable, they came to a conclusion of not being able to control him.

They assigned alot of people that worked under them to sedate him which with the healing factory increasing quirk did little to nothing because it fought the sedation very clearly. Many ended up dead trying to get him into a collar that would damped the quirks for a little while before they had him under control.

Although it was nothing to be surprised when he managed to escape his containment cell during the weekly remove-the-old-collar-and-put-a-new-one-on because he was fed up being in one or two places and he proceeded to wreck havoc in the laboratory where he was kept. He unleashed the pent up anger that ended up in a bloodlust and death of many workers.

After breaking out he finds himself in a forest, just besides an abandoned building site. The laboratory he was in being underground for more of safety reasons.

He discovers the other 'normal' nomus incubating in the abandoned building like it was seen during the start of Kamino incident. But at this point still in pain and pretty panicked he doesn't mind them bc they are dormant and just let's them be. Instead Kat finds himself roaming the site and puckering into buildings destroying them most likely.

A little delirious, fatigued and in pain he wanders off, trying to fly as much as he can which is not that much bc of fatigue. He does know how to do it, but he's still fatigued because of the testing.

He ends up collapsing somewhere in a shaded area with people that might have heard him. Most likely villains and vigilantes if the ring the abandoned site is is shady in the first place. They don't really do anything just kinda looks and if one of them is with the LOV. They might report about Kat being out. Literally.
