#kryptonian headcanons

[necer0s]

I think we should talk more about the different reactions Kryptonians could have to different radiation sources. Like obviously everyone knows that different solar radiations give them different levels of powers, and different kinds of kryptonite afflict them with different maladies.

But what about other radiation sources, the kind that those of us who don’t process radiation with our skin would never think about?

Let’s talk about how laser pointers make Kryptonians incredibly itchy, and how Kon’s friends love to tease him with them.

Let’s talk about how the Kent’s old cathode ray television always put Clark right to sleep, and how they dug it out of storage when Jon was having trouble sleeping through the nights.

Let’s talk about how neon lights make Kryptonians a little bit loopy, and how Kara and Kon once spent an evening trying different colors and models to see which ones made them feel slightly tipsy, and which made them feel blackout drunk.

Kryptonians can be weird in so many ways. Let’s have some fun with it!

hc that Kryptonian names are kind of like true names so even though Clark grew up never hearing Kal-El until he was an adult, the second someone uses it on him he twitches and instinctively leans in a little. over time, the response gets easier to ignore, but there’s still times when Bruce (or someone else?) uses it and it just kind of. snaps his attention back over to them, Clark falling away from Kal as instinct fires at the back of his mind, hey that’s my name, why are you using it?

AU of the Wayne family history. At the batkids’ insistence, Alfred finally agreed to read them an old, leather-bound book he’d been holding—a memoir of the very first Wayne.

Clearing his throat, Alfred began in his usual calm, measured tone. "Long ago, a celestial being descended from the heavens, landing in a field owned by a struggling farmer. The celestial arrived in a dazzling ship, unlike anything seen on Earth. But the farmer, desperate to survive, dismantled the ship and sold its parts, making himself a fortune. When the celestial discovered what had happened, he was furious and sought out the farmer to demand justice."

The kids leaned in, totally hooked.

Alfred continued, "The farmer, terrified, begged for forgiveness. He promised that one day, his descendant would marry the celestial's firstborn child to atone for his crime. The celestial, after much thought, relented. He gifted the farmer the rest of the ship as dowry. From that moment on, the Wayne family flourished, their wealth growing beyond imagination."

Bruce, who’d been half-listening while skimming through some files on genetic engineering from the Fortress of Solitude, snorted. "Someone clearly had quite an imagination."

Without saying a word, Alfred flipped the book around and held it up for Bruce to see. The smirk faded from Bruce’s face as his eyes landed on the page. There, drawn in faded ink, was a detailed sketch of the ship… emblazoned with a symbol Bruce recognized immediately.

The crest of the House of El.

Alfred straightened, his tone subdued. "It would seem, Master Bruce, that the promise made to Jor-El must now be honored, given that his firstborn son has arrived on Earth."

Bruce froze. He recalled the Fortress’ eccentric behavior toward him and broke out in cold sweat.

I love the idea of Kryptonians having a few animalistic instincts/habits. Like the purring and such, it makes me so happy when i read it, kicking my feet, giggling etc. I love it so much, especially when it's Conner, with him discovering new things about himself. So sweet, so perfect, gimme more sweet sweet Conner😫😫

Conner Kent x male reader

Headcanons

This is mainly just Conner and my kryptonian biology headcanons. This is based off of my own kryptonian headcanons, which you can read here.

Imagine Conner learning he can purr. Kryptonians, in my headcanons, purr at a frequency humans can’t hear. So, you two would be cuddling and he would suddenly notice he’s rumbling. He might start freaking out and asking if you can hear it, but obviously you can’t.

It takes some freaking out from both of you, and you pressuring him to ask Clark about it, for you guys to learn what it is and that it’s not dangerous. Conner ends up getting a whole book or pdf about kryptonian biology, that he barely reads.

Imagine Conner realizing he goes crazy for his partner’s scent. It doesn’t even have to be in a sexual way, he just starts salivating and going a little fuzzy in the head when you come around smelling extra ripe.

He starts realizing it’s a problem when he finds himself yoinking clothes from your laundry basket so he can keep it in his bed and rub it all over himself, since Kryptonians don’t sweat. I’m not sure if Conner would sweat a little since he’s half human, or if he doesn’t sweat at all.

You guys decide you might actually need to read the pdf Clark gave you when Conner starts snuffling into your armpits when you guys cuddle, or when he starts licking your neck or chest, without even seeming to realize he’s doing it.

Now, also imagine Conner starting to rub on you more and more since he just wants to be close to you and to smell like you. Hes like those clingy boyfriends on tiktok that are always kissing on you and whining when you have to get up for work.

Conner would just be questioning himself on his actions and the instincts his body wants to act on. his kryptonian wants are more dulled compared to Clark or Jon, since Conner is a lab grown kryptonian, but they are still there.

Conner would be weirded out by his purring for a long time, and might subconsciously try and stop himself from doing it, even though you cant hear it. It’s just kind of weird for him, maybe its because he was raised with human knowledge and doesn’t feel as connected to his kryptonian biology as he probably should be.

Imagine Conner basking in the sun like a cat. He finds out that your bed is just perfect to lay in during the sunny hours of the day, and he realizes it feels so good to lay there without a shirt on.

You walk in on him multiple times just laying splayed on your body in nothing but his boxers. If you have a cat or cats, then they are laying on the bed too, purring up a storm. They cant hear his purring, but they can sense it, so its so loud with purrs in there.

Imagine here, Conner slow blinking at you like a big ol cat. Hes also so warm to the touch, always, thanks to the sun power in his skin and body. Hes a complete nightmare to cuddle in the summer. Because he WILL want to cuddle.

Since I headcanons kryptonians have a sun organ, or a sunspot as I call it, Conner would have one too. Because of his half kryptonian nature, this organ is somewhat underdeveloped. He gets most of his excess radiation out through his TTK. But the organ starts to almost “ripen” when you two start dating.

It takes months for the organ to grow sensitive to the touch, and only when its you touching it since you are his “mate”. It becomes raw in the way a bruise is, the kind that you can only feel when you press on it. except it also makes his knees buckle almost like a button to make him collapse.

Being in a happy healthy relationship actually strengthens and stabilizes his powers because it helps this organ develop, which helps his body stabilize.

This gives you a healthy and horny kryptonian, since the sunspot developing also kickstarts his kryptonian growth. Hes active in every way that matters, but you better watch out when you guys reach around the 30s in physical ages, since that’s when kryptonian sexual maturity truly kicks in.

You guys also better read that pdf in detail, or you might end up with Conner developing organs to carry offspring. It would be extra difficult since he’s half human, but if you guys truly wanted to knock him up, then his body would allow it.

Kinda tame today but I procrastinated a lot lmao

Day 3: Alien Biology

I love love love the headcanon that kryptonians purr.. also did I mention I'm weak for pointy teef and ears..

[farshootergotme]

The batkids think the alias "Nightwing" is a reference to Batman, being the bat the flying creature of the night. Clark is very much offended when he hears about this.

The Intern: Outreach Gala

Another uneventful day for Gotham's environmental intern...

Prequel: Death of a family

The Intern: Day one

The Intern: The Laughing Fish

The Intern: Busy Work

The Intern: Outreach Gala

The Intern: Teachers Pet

The Intern: Visiting an old friend

The Intern: Chemical Valley

The Intern: Billionaire Boys Club

Gotham's public library appears unrecognizable under the cloak of night. Broad leaves shroud the outside exterior of the Gothic pillars while ivy cascades down the large door frames. Harris raises an eyebrow.

"How many forests do you think Wayne destroyed in his quest to save the planet?" He questions with a smirk.

Each grey hair is perfectly gelled out of his face. Ditching his glasses for the occasion, Dr. Harris may actually care about tonight's guests. The bouncer outside the door seemed to think the dress code was not a laughing matter.

Taking his extended arm, I roll my eyes. The security guy nods to the two of us as we walk through the door.

"Professor, if you keep saying things like that Gordon's going to question your stances on Gotham's resident Eco-terrorist. " I whisper with a smile. "....but at least 12."

Thanks to the joint collaboration between Wayne Industries, Goth-corp, and the Gotham Department of Environmental Protection. Gotham City is hosting its first Environmental Outreach Gala for the nearby tri-state area. Unfortunately for me, they saddled the newest intern to do all the heavy lifting. Young joints and all that jazz. At least I got an invite. The invites ran out before the IT guy could get one. Poor Eddie.

My heart flutters a little bit as a realization hits me. I’m actually here… surrounded by giants in clean energy and the scientific community alike. Award-winning journalists... All for the future of our planet. Passing my reflection, I smile thinking of how far I’ve come from that little river rat back at home.

A figure in the corner of my eye draws my thoughts away from the Grandma debrief. Dick Grayson, the Billionaire’s son, charms the group of ladies by his side. I take a mental note to find time to talk to him when there isn’t such a big crowd. It's been a long time since we last spoke.

The walls echo with the idle chatter coming from the rich socialites of Gotham. Waiters in tuxedos maneuver silently with a tray of champagne flutes in each hand. Considering, that most environmental professionals wear cargo pants from the early 2000s to work... the dress code was definitely a choice. I scan the room for familiar faces. Gordon flashes me a smile from across the room. I nod back. The Mayor works his way around the room with a large smile. It must be an election year.

My throat gets tight. I'm not ready for this. Looking to my right, I find that Dr. Harris has vanished into the crowd.

"Y/N L/N?" A voice calls distracting me from my nerves.

A well-dressed man strolls over. Something about him puts me on edge. Maybe it's his wicked smile or the large emerald ring on his outstretched hand. He walks with an easy air of confidence.

"Lex Luthor."

My heart does a little tap dance in my chest. The tight fabric of my rental dress makes it hard to breathe. I shake his hand politely. The party-goers go quiet around us. From the corner of my eye, Lois Lane, an investigative reporter from Metropolis, shoves through the crowd. So much for being a fly on the wall.

"I recently worked with a Professor of yours. She had a lot to say about your graduate proposal."

This cannot be happening. Memories of those long fights in the lab flash in the back of my mind. Mr. Luthor's cat-like gaze observes my reaction curiously.

I cover my face in embarrassment. That woman deserves hate mail. I could have at least been asked to type or spell-check it beforehand.

"To be frank, I originally chose the topic to get a rise outta her. Dr. Hendrix had me doing dishes for 3 weeks straight after I accidentally messed up a sample, so I wrote a proposal I knew she wouldn't like."

When I finally uncover my face, Luthor stares down at me with an amused grin.

"Even so. I'd like to discuss potential funding opportunities in Metropolis. If this is something you would think up out of boredom, I'd love to see what you can do when you put your mind to it."

That brings a smile to my face.

"Really? Everyone who I've brought it up to has been apprehensive about researching Kryptionian radiation.

"We need more scientists to ask questions Ms. L/N. Even the ones, that people don't want to know the answer to. "

The sullen green glow draws my eye once again to Mr. Luthor's ring finger... Wait, that's not an emerald. That's Kryptonite.

"Is this a personal interest of yours?" I ask slowly glancing between his eyes and his ring.

"In some ways."

An unspoken conversation occurs when he notices my acknowledgement of his strange choice of jewelry. The silence only creates more questions. Why would you wear something you know is irradiated?

"I hope to hear from you soon." Mr. Luthor concludes after handing me a business card, "There is always a spot at Lexcorp for a future scientist with your talents."

I stand there in silence watching him leave. The sleek modern design of the card lists only the bare essentials: his name, office address, and contact information in silver lettering.

Four hours ago, I was hauling boxes for the decorating committee. Huh. A nearby waiter offers a champagne flute from the tray. Respectfully, I turn them down. This dress costs more than my rent.

“Oh no. Thank you. I am… working.”

"Does work-life balance not apply to interns?” A voice interrupts.

I try not to roll my eyes at the "intern" comment. The constant reminders of my status are getting old. Starting at his perfectly buffed dress shoes, my gaze drags along the fabric of his black designer suit. Dick Grayson sure does like to make an entrance. With his dark curls and friendly blue eyes, his familiar smile knocks over my defenses. Sipping on his drink, he waits for my response with a teasing grin. His energy is contiguous. I ignore his question to ask my own instead.

“Has anyone told you that you tend to appear out of nowhere?”

His striking eyes light up with a mischievous glint.

“You have no idea.” He laughs, "It's nice to see you back in Gotham. It's been a long time."

"It has. From the rumors, you have been up to quite a bit of trouble." I joke gesturing to the envious eyes from across the room.

He raises a curious eyebrow.

“Good things I hope?”

Glancing around the room, I ignore the dozen eyes staring daggers in my direction. Academia can be such a bitch.

“Nothing too crazy: a few murders, unfounded accusations, and you might be an alien?”

Dick grimaces while tilting his head ever so slightly. He swirls his drink, yet doesn't take a sip.

“Sounds about right. Anything you believe? “

I pause... Do I play coy?

“I’m not sure an alien could do a quadruple summersault.”

Something flashes in his eyes that I don’t quite understand. For a moment, I wonder if I should have held my tongue. His suspicion morphs into the first genuine smile I've seen all evening.

“You’ve kept tabs on me Y/N.”

Before I can respond, a scream causes the ballroom to descend into chaos. Vines shoot out from under the floorboards while the native plants start attacking the guest. A woman with flaming red hair paces the floor. Her vines wrap around each person one by one…. A thorny bush springs out of a fallen leaf snagging my delicate rental dress.

Dammit Pamela. We talked about this.

Glancing at the bartender's horrified expression, I frown.

“I change my mind. I’ll have that drink now.”

[violent138]

Slightly enamoured by the idea that Bruce leaves Clark secret, romantic messages microscopically encoded in the punctuation of reports he gives him, under the pretense of Clark checking them over.

can tumblr handle my highly specific timkon headcanons (t4t bi4bi trans girls) and highly specific references to running jokes with my irl girlfriend or is this one too much

[batfambrainrotbeloved]

DC Headcanons #1

Kryptonian's have fangs, not like smexy lil skinny vampire teeth- I mean FANGS which is such a contrast considering all of them (except kara, she's a menace, whom we love) are such soft sweethearts-

But even in the most friendly grin there they are front and center a reminder this is an apex predator who could very well rip your throat out.

AKA- While humans were endurance hunters, kryptonians for ambush and brute force hunters- and it shows even in their "modern" genetics.

[dio-icarticaae]

It's a minor pet peeve of mine when somehow de-powered Clark (usually via red sun radiation) is portrayed as just being a regular human. He's not.

Kryptonians are aliens, and logically, for Clark to be able to do all that he does under a yellow sun, Kryptonians should be able to do something similar (though far less powerful) under a red sun too. Why would Clark be able to take in energy from the sun if Kryptonians didn't do the same on Krypton?

A kryptonian under a red sun (or depowered Clark) should still have keener senses than a human and be able to see in more wavelengths; maybe still able to move a little bit faster than a human could or be a little bit stronger. Be more durable than a human too. The mechanism for heat vision would still be there, just less powerful (maybe emits closer to infrared?) Maybe a Kryptonian under a red sun can't fly, but they can glide/hover/jump a lot further.

Anyway, the point is: Clark's an alien. Even without his powers, he's still an alien.

[lambcow]

Ok but imagine young Clark coming into his super-hypnotism powers as a young kid and Martha Kent is not having it because you can only argue with your two-year-old so much if they can sweet talk you into anything they want.

She figures out really fast that it's all in the inhuman eyes - and really, she should've known that gorgeous shade of blue was too good to be true - so when Clark gets in a fit and she just knows he's going to make a demand, she avoids direct eye contact with her sweet little angel. She knows he's not doing it on purpose, he's just a little kid, after all.

But then, he has to go to school, and Martha knows Clark won't do it on purpose, but her little baby is a charmspeaker and is accidentally going to manipulate the entire world around him into whatever he thinks he wants and that's just not going to fly!

So, Martha experiments a little. The next time they go into town for the day, Martha hands Clark a tiny pair of sunglasses to wear all day to see if lenses even make a difference. It's not that he's never worn them before, but she needs to know if he can influence anyone if he's not looking directly into their eyes. After a day of errands and several pleading looks and what are certainly puppy eyes from Clark from behind tinted lenses to no avail, Martha has her answer.

Their last stop of the day is an antique shop on Main. Martha greets the man at the counter like you only can in a small town and asks if he has any supplies of old glasses they can rifle through for Clark, just in the meantime until they can get his eyes checked. Just to limp along. It's a lie, Clark doesn't need a prescription. But in a box of used glasses, there's always the chance Martha will find what she needs.

Gary (that's his name) points her toward a dresser down the room and tells her there's a drawer filled with costume glasses and the like. They find a tiny pair of glasses for Clark and he complains at first that the world "looks funny" but then he blinks twice and looks around again and, with a grin, says "Never mind - I like them, can I keep them?"

And that's how Clark Kent starts wearing glasses.

As he gets older, continuing to grow up and especially while he's still shorter than his ma he'll occasionally glare up at her from over his lenses petulantly as he tries to get his way and it brings a whole new weight to the phrase "Don't give me that look, now, son," because Clark knows that she means not to use his Kryptonian eyes on her to get his way. It's not a secret any more than Clark being an alien is a secret that Clark can get people to do what he wants. But the few times he's done it have resulted in the biggest groundings of his entire life and more chores than he's ever wanted to do. And not just manual labor chores, but the kind of chores ma knows he doesn't like, because a ma always knows how to make a chore a chore.

In high school, for all that Clark is not very popular and has that whole quiet nerd persona going for him, he has that cute kid with the glasses Kryptonian Gaze™ down to a seductive art and he's not even trying. Because. Hello? B-i-o-l-o-g-y. So, yeah. That over-the-glasses glance from across the room? It's a whole thing and lots of girls (and guys?) are super confused by why they suddenly think Clark Kent might be super hot. Then when they look again but it's just Clark sitting there with his normal glasses again? They're not so sure...

He doesn't like to use his super-hypnotism because it feels like cheating, but depending on the circumstance he will. It's not that different than using his other abilities after all, right? If it's for the right reasons, is it?

While he's working at the Daily Planet, he'll use it on occasion to push his advantage for a story for that one extra detail, to get access to a room he might not have otherwise, to sneak into places he might not have, to make people forget his face, his name, their conversation if it was a particularly sketchy place... it's all a simple tilt down of the chin so he can look people straight in the eyes over the rim of his glasses and ask a pointed question or say something or suggest something and then....

As Superman it's different. As Superman, he never wears his glasses. He's all heat vision and x-ray vision, micro and macro vision. As Superman, he does what he needs to to save people. Sometimes that's telling someone to get to safety or go home, call 9-1-1, run, stay here, be quiet.. it's a hundred things as Superman. Sometimes it's asking guards for passcodes or entrance, sometimes it's to turn off surveillance altogether. Superman does what he has to do.

[mamawasatesttube]

the geoff retcon is just so poorly done in so many ways. when i think abt it i just rly do have to roll my eyes because it wouldn't even be that hard to be like "actually, paul westfield was duped by agenda under orders from the contessa" and have that as the explanation for the introduction of luthor dna instead of paul westfield's, if you MUST include it. like that way it doesn't blatantly contradict the entire luthor plotline with mae in reign of the supermen, and it could've been a reveal to luthor himself, too. that couldve been fascinating ESPECIALLY in the context of lex having baby lena in that era, until the y2k event.

but fuckign. why do that when we can directly contradict kon's entire origin story which explicitly states he escaped before they were able to put control codes in his head. and when we can also just completely dismiss the ethics of "they [wanted to] put control codes in his head" in favor of "what if... some genes... make you BAD..." which is just very thinly veiled eugenics that the narrative entertains, for some reason. frankly, imo, lex was far more interesting as a character in every plot other than this, because he became so one-dimensionally evil in a very boring stock "manipulative" way. and we didn't even get a single mention of lena in all of his "my son" bullshit. using the contessa wouldve been such an easy and perfect way to tie it all together!!!! but sure. why do anything like that, right geoff.

Can I request Mark in subspace with a kryptonian like reader after a long day as a hero?

Mark Grayson x Kryptonian male reader

Headcanons

Yall heard about season 3 of invincible? Anybody else as excited as me? This request is kinda old, but ive kept it until now. I write when I got inspo and time, and my school and internships taken all my energy out of me, but life goes on.

Being a hero was hard, both you and Mark knew that. You were a kryptonian, somehow having ended up in this universe because of a dimension scrambling situation, like flashpoint or similar.

For one reason or another, you stay on earth and start dating Mark, the two of you first growing close in the beginning because your powers were so similar. He truly and completely fell in love with you when you wrecked Anissa, since Kryptonians main weakness is kryptonite, and it most likely doesn’t exist in this world.

You two dating allows Mark to feel actually small and weak again, like he doesn’t have to carry the entire fate of the universe on his shoulders, since physically you are stronger than him, more sturdy, with more powers.

Being able to let go is something Mark hasn’t been able to do since he got his powers, as he’s always felt like he needed to be on edge and ready for everything.

But then you waltzed in, grabbed his hand, and dragged him out, put him on his knees, and made him cockwarm you till his head was so nice, warm and floaty.

Well, in reality it was more you guys flirting and spending a lot of time together, leading to Mark mentioning he had never sucked anyone off before, and you offering to let him try on you. He tried in the beginning, he really did, but Mark realizes how good it feels in his mouth.

You knew at least enough about subspace to safely take care of Mark as his bopping head slows down and his eyes become almost foggy, his shoulders slumping as weight he hadn’t even thought about being there went away.

Having your hand run through his hair, his nose pressed against the smattering of hair above your cock, no expectations and no hero work, made his head feel silent in what felt like too long. He could have almost cried, if you had not wiped his tears away and cooed down at him.

After that, you two started officially dating. To everyone else you guys were just dating. To powerful juggernauts who were only able to find comfort in someone who was like themselves.

And yes, that was part of it. There was no need to be careful with a guy as strong as yourself. There was also just the fact that you two got along and had a lot in common, which gave you guys more than enough to talk about.

Though, there was one thing about your relationship what was somewhat out of the norm. like the fact that Mark wore a cock cage most days, as well as a nice sturdy plug. It hadn’t even been you to offer the idea in the beginning but Mark himself, since the pressure and weight made him feel almost secure.

There was also the fact that Mark would come home from long missions, crawling into your apartment through the window, and laying down on your lap. Be that lying completely on your lap, or just laying his head on your thighs so you could play with his hair.

It was more common than you liked that you had days where you would need to undress him and bathe him since he was so tired, and just wanted to be pampered. Mark always got so nice and pliant, leaning against you and kissing at your neck as you move him about.

On days where it was a normal patrol, being cuddled and kissed like every other day was good enough. But on days when things had been rough, Mark truly would want to get out of his head.

That was when the cage and plug he wore got put to use, so it was there as comfort, but also a sign of your dominance and control over him. And if that wasn’t enough, your strength was enough to overpower him, even when he wanted to be bratty and fight back.

Some days he would get bratty, when Mark felt like he needed to be punished, or just wanted it to hurt a little more. You were probably one of the few beings in the universe that could spank him till he cried, and you were definingly the only one he wanted to do it.

Some days he needed to be bent over your lap, your super strength so easily holding him in place as you tanned his hide until it was such a nice glowing red, and his sobs were loud enough to make the glass in your windows shudder.

Other days, Mark craved a different type of heat. Luckily you could control your heat vision enough to burn just enough to leave a mark, but not enough to hurt him more than needed.

On the opposite side of that, were days when you wanted to shake it up, instead using your ice breath. It was extremely effective when used against his chest, where his nipples got so hard Mark would cry just from having them touched. Or when you needed him soft to get the cage on him, nothing quite like a cold blowjob.

But, on most days, Mark was well behaved and just wanted to be loved and held, sometimes fucked, sometimes he wanted to do the fucking, but. Being loved was what mattered the most.

There were times when all he needed to get into subspace was being held in your arms, and other days you two needed to spar. His favorite would always be your cock in his mouth, in any way you would offer it to him.

Mark knew he could always safeword, so he would go for as long as he physically could, and it honestly helped him get better at holding his breath, since Kryptonians rivaled Viltrumites in size and thickness.

Mark loved coming to you and giving up control, even if it was only for an hour or two. There were days when that was all he needed, to just know there was someone there to take charge of him, who would be proud of him and worry for him, and not his powers.

[loverboybrightsideghost]

one of my favorite clark headcanons that i have (that is completely unsupported by canon) is that he's transgender by kryptonian standards. martha and jon kent raised him as a boy and as he grew up he never had any reason to doubt it at all, he was like yeah i'm a boy, makes sense. and then he gets to the fortress of solitude for the first time and it turns out how Gender works on krypton was just Different enough that clark doesn't really fit the kryptonian standards of whatever he was supposed to be. bonus points because this makes him feel like even more of an outsider as a kryptonian, even if he's the last one left.
