My brains back on the Alien Izuku AU so, uh,

Sorry? But not really

Alien Izuku who crashed landed on Shouto’s farm… and they spark up a friendship (and romance?!)

(Idea from @/SunnySokka on twt!)

(Its 3am and wow i want an alien bf???)

You wiped sweat off your brow with the back of your wrist, likely smearing more oil over your face. You let out a groan as you tightened a nut, you crashed your ship on some planet. It was like nothing you had ever seen, it was truly a thing only a mad man could have come up with.

You had gotten lucky, aliens had saved your life. Well, one alien in particular, his name was Deku. He was smaller than most and rather scrawny yet, he still seemed to tower over you, he had pale green skin that shone almost blue in direct sunlight. It was a sight to behold, his dark curly green hair was messily sat upon his head. He looked like he had rolled right out of bed, which had been likely as he had been a little later than usual. 

He had two small ears, you had assumed anyway, on his forehead. They matched the colour of his skin and would occasionally twitch. Just behind his ears, sitting on top of his head were dark green horns that went into a neon green gradient. His green eyes with a black sclera were squinting due to the sun.

He had been so kind and helped you out when you really needed it, he took you in and looked after you. He had given you special devises, they were light years ahead of earth and their technology. It was like comparing Albert Einstein and a toddler.

You had been on this beautiful planet for what you had guessed had been a few months. The scenery was incredible with lush green trees with pale grey, almost green bark and beautiful purple leaves that filled the branches. You could see a few purple and white fruits hanging on the trees, when ripe they were extremely sweet and delicious.

The grass was a dark teal colour, spreading far and wide. The dirt was orange and extremely crumbly, the crops that grew from it doubled the size of earths crops. The only downside being that the rain was acidic and you couldn’t leave Deku’s home.

“Can you hand me those pliers?” You questioned, pulling back from your task to gratefully take the tool from Deku. A wire looked like it had melted, that would be of no use. You yanked it out of the socket with the pliers, moving back with your own force.

You let out a sight and jumped off the step ladder, you fell to the ground, instantly leaning against the rocket. “Tired?” Deku had made a translation collar for you, so you could understand each other. The first few days before it came had been extremely difficult. You nodded your head in response, the sun was extremely harsh today.

Deku bit his lip, playing with his finger. “You could take a break? We could go inside.” You toyed with the idea for a minute in your head, who knew when or even if you could fix the rocket. “Yeah. I’d like that.” You nodded, Deku’s beaming smile almost stopped your heart. He stood and helped you up, his claws lightly grazing your wrist. His hands had patches of scales, just like the rest of his body. But rather then be repulsed you found yourself liking the feeling of his scales, despite the rougher texture.

Deku excitedly lead you inside, talking about how their president was the best and asking how yours was. All you could do was scoff in response, this caused confusion to spread over his face. You waved him off, you didn't need to tell him about the horrible things that happened on earth. 

He sat down on a sofa, it was the softest thing you had ever felt before. It would be so easy to fall asleep here. You took a seat next to Deku, leaning into his incredibly warm body. You looked as a picture suddenly appeared on the T.V. The president standing proudly to announce something, you weren't paying much attention.

Having Deku so close had your mind running wild, yet you didn't want to pull away. Everything was insane, one minute you had been flying to help out some stranded comrades the next your sucked into a worm hole and thrown through time and space. 

Even if you did fix the rocket, there was no guarantee the worm hole was even still there. There was no guarantee you were even still in the same galaxy. The thought caused a small amount of fear to build up, without noticing you instinctively clung closer to deku.

His arm wrapped around you, his tough skin rubbing against your soft skin. He watched intently and listened to every word that came out of his mouth, you found it adorable how he hung onto every word. From what you knew it was deserved, the planet had been once devastated by a war. He rose from the ashes and rebuilt the world with the survivors, and it became the world it once had been.

You were glad you had came now, you couldn't have imagined how terrible it must have been to see a once beautiful land turned into nothing but rubble and ash. "Hello?" Deku called, a worried look on his face as he waved his hand around your vision. You let out a hum, looking at him questioningly. "Are you okay? You seemed deep in thought." His voice was kind, but laced with worry.

You let out a little laugh. "I'm probably never going home, you know?" You saw Deku's lips twitch up, his ears wiggled slightly. "Oh?" He questioned. "I don't even know where I am." You knew they probably had the technology to and yet, you stopped Deku before he could speak. "I'm not sure I want to go back." He cocked his head, reminding you of a curious puppy. "I really like it here with you Deku." Your voice was soft as you gazed at him, waiting for his reaction. The sight of his entire body turning red had your jaw dropping.

"Yo-you wha-at?" He stuttered out, you almost squealed at the cuteness. Never in your life did you think you would literary see someone blushing from head to toe, he quickly composed himself and wrapped you into a tight hug. "That makes me happy." You could hear his smile in his voice, it brought a flush to your own face. He pulled back, looking you in the eye. "Wont you miss earth?" He questioned, you thought for a second. "No, I don't have anything worht staying for back there. Here I do." 

Deku seemed gleeful with your confession, he wrapped you into another tight hug. Your eyebrows raised at the sound of chirping that came from his chest, the adorable sound caused your smile to grow impossibly wider.

Deku Sketches...

I have no idea what I’m doing but look, I tried drawing Deku in four AUs!

Left to right (up-down): Nerd/Glasses Deku in No Quirk AU, Assassin (thief? traveller?) Deku in Fantasy AU, Alien (slave dog alien) Deku in Space AU and Rabbit Deku in Animal AU

An Open Invitation to Explore the Unknown

I want to revisit this idea in acrylics at some point because my dying markers are not doing this justice (consider this a proof of concept or whatever)

fic of inspiration here

[vtimbertiger]

My brain is in hyperdrive and I am determined to figure out what Alien Izuku's Homeworld is like based on his adaptations

By sheer technicality this is gonna be full of spoilers so go read the fic "Our Hearts Speak for Themselves" by @/lettertoelxse on AO3

( This is a long post ❤️ )

For the sake of this, I am assuming that it is a carbon-based life system as earth with similar molecular building blocks (as much as I love the idea of a different molecular building block [i believe sulfur or phosphorus has been proposed in the past as potential "life starters"] I am not smart enough to build on that).

Homeworld is larger/denser than earth with a greater gravitational pull & atmospheric pressure, with a thick/humid atmosphere, and a temperate-polar climate throughout.

(1) Planet: Larger &/or Denser than earth

This is mainly pulled from our first introduction to alien Izuku, as he leaps at Katsuki from the shuttle cockpit to the ground with ease. I had pictured Izuku as sitting prior -- or at least an awkward crouch since he was hitting the panel from the inside -- before launching himself out of the ship.

Him being accustomed to greater gravity, then landing somewhere with less pull, would give him a greater advantage in mobility

The gravitational difference wouldn't be too different however -- think about the moon landing videos and how slowly they move. With an actual atmosphere pressing downward, there may be a different effect.

(2) Atmosphere: greater pressure

Couple reasons for this one. Firstly, because of the planet being larger/denser would in turn create a greater pressure.

This would also be supported by point (1) when Izuku leaps: less gravity, less pressure holding you down, increased jumps.

Second, his shuttle was highly pressurized when they finally got the panel off -- "like a cap blowing off a soda bottle". Admittedly, idk how the crash might impact internal pressure, or the pressurizing process of our own space rockets. My assumption is that his ship would be pressurized to (or close to) Homeworlds pressure for comfortability and health of their astronauts.

I'd like to think of the difference being only slightly more extreme than human at sea-level climbing to mountain-elevation -- lest Izuku be turned into a blobfish upon exiting the shuttle lol

(3) Atmosphere: increased humidity

Like walking through fog, the kind of fog that makes it hard to breath, you know the kind.

The only 'obvious' connection is based on Katsuki's description of Izuku's skin being "delicate" (frog) -- constant humidity, less need for thickened skin.

Now here's my outlandish theory: it's because Izuku is greenish-blue.

Assuming Izuku can see (maybe a little more than) the human-visible-light spectrum (IR-ROYGBP-UV), what purpose does being green have in his environment if he can't blend in?

Well, what if the atmosphere is so humid/dense, that not all the wavelengths can penetrate it?

^This is how light penetrates the ocean on earth. Only blue & green light are visible at deeper depths, and anything yellow/red/purple would appear more grey(blue)-scaled (unless there is the introduction of a visible-wavelength light source separate from the sun).

A lot of deep sea creatures are actually pigmented with reds & purples, but in their natural depths they would appear as their colors value (light/dark -- very often dark)

So, being blue-green in color would mean blending in with your surroundings, arguably better than if you fell somewhere else of the spectrum. And, because you are a visible color, it would make it easier(?) to identify your own kind for species-prosperity or whatever.

I know I've been talking about the deep deep dark ocean, but I'm really only proposing a limited visible-light spectrum seen below for Homeworld's atmosphere. (For logic's sake and for my own selfish reason).

[Notice how the only colors not visible are oranges and reds? :) ]

[Imagine being capable seeing all the colors and more, but never actually getting to see them. Then you crash arrive on a new planet, and you're greeted by a field of pink flowers, an orange sunset, scarlet eyes, blushing cheeks. I think red would immediately become my new favorite color. ]

[there's also the red marker and the markings on the map, the "red building"/barn that loosely means salvation (because your night-blind savior is no longer tense beyond belief at the sight of it), corn fields (probably yellow but shush), fucking All Might -- but these aren't as important to my point]

(4) Atmosphere: it's a dim world

Pulling from point (3) above, not all light is able to penetrate the atmosphere, which would result in it being darker. Examples supporting this: (A) Izuku is bioluminescent (eyes & freckles), which is only really beneficial in darker environments where those lights can actually be seen.

(B) Izuku can see in the dark. Again assuming he sees normal color, and not some other form of vision. This would be an adaptation for limited light environments that would quickly become overstimulating/painful in a well lit environment (good thing Izuku crashed at dusk).

(5) Climate: Temperate & Colder

This is supported by how we know Izuku is endothermic (able to generate own heat). Katsuki mentions multiple times at how warm Izuku is, and gives the impression that he's warmer than the average human.

["only now realizes how warm Izuku’s palms are" ; "He’s warmer than Katsuki would have thought"]

While endotherms are found in every climate, ectotherms (requiring external heat for function) are restricted to warmer zones (with some species being able to function at colder zones).

On earth, endotherms in colder/polar climates have two methods of regulation: first would be natural insulation (combination of fur and fat), secondly (the one that applies to Izuku) is to have an increased core temperature (typically above 100°F/38°C). [which is real unfortunate for Izuku since he crashed in what sounds like the US Corn Belt lol].

(6) Foliage:

I think foliage on Homeworld would have to be red-ish in color for any chance at photosynthesis or like-processes to occur. Objects absorb colors that they don't possess and reflect colors that they do (example: it's why you where black in the winter (to absorb all light) and white in the summer (to reflect all light) (because light is a form of energy)), so if red light doesn't reach wherever this plant is growing, then all other light get absorbed and turned into energy (min-maxing the system) (this might also explain why many deep sea creatures on earth are red-ish -- gotta get as much light-energy as possible in harsher environments).

^this still works with point (3) because the reds would fall on the grey-scale of the environment.

End Thoughts:

What does all this mean for Alien Izuku on earth? I've kinda mentioned this previous posts, but he would probably become very overstimulated by how bright our world is. He would also likely "dry out" the longer he stayed without having a constantly high humidity. He would also start losing muscle mass if he doesn't put any additional effort in remaining fit due to the lessened gravity/pressure if he ever stayed (like how astronauts have specialized work out routines to remain strong in space).

What if Katsuki went to Homeworld tho? Probably convince himself he's drowning in their atmosphere. Might also need an oxygen mask for supplementation. He would be slower and more sluggish, definitely would not have great agility with the increase in gravity/pressure. ...He'd probably be fine with the low light tho.

A brief interruption of Cowboy Yaoi for Alien Izuku

Y'all, go read "Our Hearts Speak for Themselves" by @/lettertoelxse , it's a very cute oneshot

(I'm not retyping these tags out but I stand by my deduction on Izuku as an alien species ⬇️ )

**it's not even about having "pointy teeth", it's that he has legitimate fangs. The kind of teeth used to rip throats out of prey

[vtimbertiger]

Doing some ... field studies .. or something

It's always humans being fascinated by aliens or aliens being fascinated by humans (usually in fucked up science experiments in both cases)

Why not make it a mutual fascination?

(More or less a continuation from this post, based on this fic)

Some Physiology Ramblings Below

Antennae: act as a combination of "taste"/"pheromone" receptors (like insects & mollusks) and frequency detectors (like cats/dogs & some fish) -- ie. they are ridiculously sensitive to any type of physical contact.

With that idea, to minimize sensory overload, he wouldn't have external ears (ears that funnel directional sound) nor a great sense of smell (debatable) and taste.

Some carnivorous species (especially cats) have a limited taste pallet compared to omnivores (cats can't taste sweet flavors)

Eyes: Izuku needing sunglasses during the day because he can already see in the dark and that extra light really hurts. His eyes somehow being able to "store light" to be amplified & refracted later.

Or Izuku's pupils constricting so far they're almost gone, leaving only black sclera & iris (which kinda lines up with actual alien depictions in media)

Bioluminescence: being able to practically strobe-light his freckles like cuttlefish/squid to mesmerize/stun prey (or other reasons)
