The space program took a whole month off of development after Tektite's accident, so that Slate could have the time to perfect their leg. They'd already been working on articulated flaps for in-atmosphere steering for Feldspar's ship - conserves fuel to not use jets for that - and hey, an artificial ankle is just another type of flap to articulate, right?

Gossan wasn't so sure - especially with Slate's full-tilt approach to experimental engineering, at odds with Tektite's trepidation - but all of the founders agreed that the program could wait until their neighbour was back on their feet. And to Slate's credit, Gossan had never seen them show as much sheer methodical focus, before or since. This was somebody's limb here, after all: their ability to move of their own accord, their ability to get out and about in the community and do the things they love, their ability to still feel like their body is their own. Slate was hardly about to phone it in, or risk any wild experiments when it came to Tektite's comfort and requirements.

It took several iterations, and several difficult test walks around the town square gripping Slate's arm, but together the pair of them worked out a final model that's been serving Tektite well to this day.

(...Of course, the dedication and focus that so pleasantly surprised Gossan only made Slate's awkward avoidance of them after their own accident sting even more. Was it really that hard on their poor guilty conscience, to think about doing something similar for a friend, instead of darting their gaze away just short of Gossan's face?)

So this ficlet-ish thing was inspired by @hydrachea, nsfw super genius extraordinaire, but also by the fact that in addition to Boothill's left eye being cybernetic, I like to hc even the parts of him that look human aren't fully natural. I mean the dude eats bullets, after all. I think he should also have vents in his mouth so he can literally blow smoke/steam, it would look super cool. Think Father Gascoigne or Studio BONES' Todoroki. We as a fandom deserve that!!

So anyway, of course, sometimes these vents get blocked up and need to be cleaned manually. Thankfully, Dan Heng is super helpful ☆

Like there's one day where Boothill is lazing around in the archives, fresh off a bounty and happily soaking up the luxury of the Astral Express after however long he's spent tracking his prey through all the dust and dirt with almost no rest.

Boothill likes it in the archives. It's not silent, but it's quiet. There's no music and only muffled voices from outside, but there's the hum of all the computer systems. It makes for a nice place to hide away and recharge when he's just finished exhausting himself.

And besides, Dan Heng is there.

Sometimes the two of them talk back and forth, but today it's mostly quiet...except for-

"I didn't know it was possible for you to get sick."

...Except for Boothill having to constantly clear his throat. That's the thing about your mark trying to flee into the desert. You either go after them and get sand everywhere (and even worse, sticky sand once it gets all bloody) or you wuss out and lose out on the bounty. Personally, Boothill likes being able to afford to eat.

"Grit's stuck in a vent somewhere, 'n' the usual maintenance ain't gettin' it. I'll prob'ly have ta manually dig it out." But later, when he's not laid out half asleep on Dan Heng's extra futon. Usually after a chase as long as this one took, he can shut down for almost a full day. He doesn't want to get up yet.

Something shadows over him, and reflex demands Boothill's eye open. Dan Heng steps around him on his way to some drawer built in the wall on the other side of the room or something. Boothill closes his eye again.

From under his hat he hears the sounds of rummaging, drawers sliding open and shut, the swish of a long coat. The shadow returns.

"Sit up, just momentarily. I have something to help." And Boothill groans a tired don't wanna, but he does it anyway, he hauls himself upright into a kneel. And then he sits up a little straighter because he realizes Dan Heng is standing right over him.

Dan Heng tells him "open your mouth," and Boothill's jaw pops open without his permission, without even a second thought, and hey, what protocol in there ok'd THAT?!?!

Before he can really unpack whatever the heck that just was, though, Dan Heng murmurs for him to say so if he needs them to stop, and then he's sliding a long, hard rod down Boothill's throat, tipped with some soft little brush he probably uses for all his fancy archival equipment.

Dan Heng tells him the handle of the brush is straight and can't be bent, he needs to move his head to be able to reach the vent in his throat. Boothill hums affirmatively; he can't do anything else with his mouth occupied.

Dan Heng's free hand holds him by his jaw, tilts it up slowly but firmly so he has to look straight up at him.

Boothill feels dizzy.

The cycle of blue blood through his artificial heart whirrs just a bit faster, his temperature sensor pings an internal alarm to warn for imminent overheating. Boothill curls his fingers into the guard over his knee as Dan Heng carefully brushes at the dust irritating him. All other sounds- the hum of running equipment, the occasional beep from the computers, the noise of the crew outside of this room- seem to pull away, until all Boothill can focus on is the steady and measured breathing from the man above him.

"Almost done."

Thank the aeons, maybe one of them likes him after all.

"Your tongue is in the way... I'm going to hold it down, ok?"

Nevermind.

The fingers holding his jaw curl around his chin, thumb slipping past open lips to dip into his mouth and pin down his tongue. One of his teeth catch on the digit, breaking skin just enough to bleed a drop where he can taste it. Dan Heng doesn't even flinch. Another temperature alarm pings off in his brain, then another, then another.

Boothill has never been shy about eye contact but oh, god, it nearly kills him when dull green irises flick away from their task and look down right at him as his mouth is held open. He quickly squeezes his own eye shut for some relief.

With his vision cut off, the rest of his senses automatically recalibrate to compensate. He can hear every breath even more distinctly now, every soft inhale and exhale, feel the strain in his neck, the softness of the brush, the hard floor beneath his knees, the hand holding his jaw and the fingerprints that feel like they should leave burns in his skin, the taste of Dan Heng heavy on his tongue-

Forget it, eye open, eye open!!

"Alright. There's one last pebble stuck."

Boothill had been trained to endure torture, back on his homeworld. It was part of being in a gang, part of being a bounty hunter.

Somehow, keeping himself quiet and still as Dan Heng inches the brush even further down the back of his throat is a profoundly similar experience.

The seconds tick by, Dan Heng's brow furrowing, face growing ever more concentrated and Boothill struggles not to watch him too closely, fights down the noise that suddenly tries to escape him as the brush withdraws-

"Swallow."

Stars and aeons, Dan Heng is going to be the death of him.

Boothill swallows. He feels it when the movement finally dislodges the loosened pebble from his vent.

His face feels shockingly cold now bereft of touch, even though Dan Heng's hands are always cool. He asks to see, and Boothill's mouth is already open again to show him, even as he belatedly realizes he could have just told him it had worked.

"Good." There's the slightest smile on Dan Heng's lips as he finally, mercifully, leans back out of his personal space, goes to put away the brush. "That should feel better now." Boothill spends a moment dizzy and dazed, feeling the need to blink spots out of his eye even though his vision is clear. He still hasn't moved off his knees.

What the fudge.

thinking about Tron program bodies again, blood is not enough for me, where are the wires and fans and plates of metal that bend and snap

I have this vague image of an anatomical diagram of a program

Energy Circulatory System - the Blood, also the digestive track bc they don't have food, Mouth to throat tube to processor located center, near the disk port, it processes and then pumps the energy through the lightlines of the body, if a program overclocks themselves enough, they can suffer burnt or even ruptured circuitry

Energy both fuels the program and cools them off, when cooling processes are activated, the energy will be cooled off by nearby venting processes and will then be circulated throughout the body

Venting System - Similar looking to lungs, two fans that sit within the upper chest, one on each side, subtle ducts can open along the sides of a program to release extra heat (they sorta look like gills, ticklish), Most of the cooling is done through this system, Vents work to expell air through the nose, mouth, and additional vents and ducts, some programs have extra vents for their functions (Mechanic need more bc they work in hotter environments)

The Disc Port - connected directly to the morherboard of the program, this is why if programs are hit there, they will derezz, sorta like a brain (head wounds are not fatal), all processors are connected via wires to the board

Processors - part of the motherboard, eyes, ears, nose, tongue, all the senses are split up into different processing units, These usually have a mechanical unit, like eyeballs, that connect to the board with long thin wires, essentially the nervous system, but centered around the disc not the head

Internal Systems - internal sensors and diagnostics that regulate the body, the Endocrine System, Connected to a programs personal display, will update with warnings and display whatever parameters needed about the body

"Bones" - programs don't have bones, but they do have metal tubes that house their more delicate pieces (wires), Some programs (security) have more reinforcement around vulnerable areas, like the throat and chest, with the plating sometimes even being above the skin, Additonal plating can be added to the forearms and calves without much modification, further integrated armor is an arduous process

Derezzing is still a thing, parts of a program will maintain integrity to a point, then they collapse into voxels, Not all pieces will derezz, if that threshold isn't met, the pieces will remain in their form, basically, if you want to fully derezz a program you have to grind them into voxels, otherwise the bones and other stuff are unlikely to derezz until the energy runs completely out (usually a few days, or the Grid equivalent), where they will then turn into a pile of voxels

Voxels and Energy both evaporate, losing their vivid technicolor hues, until they turn a dark soot grey, at this point they disappear leaving a thin dusty film behind, it's hard to clean and slippery

Cyborg!Caleb and his strange affectionate habits

you love your part-robot boyfriend, but he’s a little strange!

✎ᝰ a/n: he was supposed to be a puppy for this series… but then this happened, so now he’s a cyborg. i think you all will like this one. enjoy!

ִ ࣪𖤐

❥ he's always scanning you. day or night, awake or asleep, caleb will take it upon himself to check your vitals and health on a normal basis. just a quick little holo-scan from his eye is all he needs. and from the amount of time he already spends staring at you, this is a pretty easy feat.

he knows things about you that you haven’t even figured out yet. you’re gonna catch a cold soon, but he already knows from your white blood cell count. you might not know your period is coming soon but caleb has always got your back and tells you when you’re ovulating or preparing for a period. of course, you ask him not to do it all the time. and of course, caleb is insane, so he doesn’t listen all the time. it’s very intimate to him to know the inner workings of your body.

❥ he can’t sleep next to you (and he tries to fix it). caleb does not sleep in a normal human bed. instead, he sleeps in a tube where his charging port is and asks (begs) you to sleep with him there. and while you do indulge him, it’s very uncomfortable for your human body. even after he tried to enlarge the tube by rebuilding, it’s still not ideal.

he’s so upset that he can’t sleep with you in your bed that he’ll charge himself during the day just so he can be next to you at night. except, he can’t sleep without his port, so he just stays awake next to you, exhausting his energy by admiring you. he talks to himself and you during this time and if you ever stir awake from his murmurs, he’ll apologize and lull you back to bed.

❥ he makes modifications for you. caleb doesn’t wish to be any less than perfect for you, so he’s constantly making tweaks and refinements to his system and body to better adapt to you. like the time he installed a heating system inside of him because you always flinched at how cold he was. or maybe the time he installed more sensors in his wires just so he could better feel your touch.

and while to an extent it is sad, caleb will find a way to make it more fun. he’ll adjust the size and feel to his appendage for your pleasure and he’ll also install vibrations to his fingers if you really ask. or maybe he’ll do something silly like add confetti to his hands so that he can pop them out at celebratory moments.

❥ he forces himself to eat for you. caleb doesn’t really need to eat to keep alive. in fact, he prefers not to because sometimes it’ll make his metal tummy feel weird. he’ll never tell you that, though. he loves you too much to let you know that all the meals you prepare for the two of you are actually making him a little sick.

but he’s gotten better at keeping them down. he modifies his stomach to hold food better and slowly he’s working up toward more intolerable foods—such as spices. one day he hopes to be able to stomach everything you make, but until then, he’ll lie day and night to keep you happy and to bond with you.

❥ he’s very picky at his face. the face is the only thing caleb has that’s human-like. because of this, he’s constantly picking at it; snipping at his hair, shaving, cleaning the skin there, everything he can do salvage what he can of his human form. he also prefers it when you touch his face rather than any other part of him, simply because that’s where he can feel skin to skin contact.

he’ll constantly ask you if he looks handsome as a joke, but it comes from a deeper insecurity within him. he wants to ensure you still enjoy him even as he is, and once he gets your reassurance, he’ll start to remind himself every day that he doesn’t need to worry as much about his looks. because you love him anyway.

❥ he takes secret recordings and photos of you. there are two sides of this, the sweet side and the suggestive side. he loves recording your laughs and photographing your smiles with his system so he can rewatch them when the two of you apart. especially if he’s on a mission and away from you for an extended period of time, he’ll make to stock up on your beauty before he goes.

the suggestive side is more like… a few cheeky pictures of you dressed down or right after sex. maybe even a video of your butt while you’re walking away from him. he’ll never want to take videos or pictures of you during intimacy without your consent, but these small provocative pictures of you are more than enough to satisfy him. if you ever do give him consent to make what is essentially robo-homemade-porn, he’ll play it holographically and watch with you after the fact.

❥ he flies you everywhere! come with caleb on a joyride in his arms. he’ll fly you across town or just around the neighborhood! not that he can’t drive you, he just thinks this way is more fun and special because you’re clinging to him the whole way through. no need to be scared of heights because he’s got you tight in his grip and has 8 backup protocols in case he malfunctions mid-air.

you found it a little embarrassing at first, being a spectacle in the air for everyone else, but now it’s fun! you’ve grown so accustomed to being in the air because of him. and since you have such a fun time, anytime you’re down in the dumps or need fresh air, caleb is always there to take you on a little ride to cheer you up.

❥ he has you engraved. it was part of his hardware modifications, but he once asked you to write your name on a piece of paper, and a week later, he has that same writing etched onto his nape. you couldn’t believe it at first, but it was an exact copy of your handwriting now just seared into him.

he tells you it’s so that he can feel more comfortable in his “skin”. knowing that you’re a part of his new robotic body makes him much more accepting and happier of it. he doesn’t hate it as much, not when you’re always in the back of his mind. ִ ࣪𖤐 hey gals: @chersyluvs , @otomegamesforlife

The note about the Dai Bendu being the origin of the Galactic Republic's Roundel was originally written as "Bendu monks" in 2002's Attack of the Clones Incredible Cross-Sections and in 2007's Complete Cross-Sections. This text was removed, however, in 2018's Complete Vehicles and 2020's Complete Vehicles, New Edition. The Dai Bendu do exist in Canon though, thanks to mentions in Star Wars Outlaws and various DeAgostini reference works.
