You should definitely do ultron x supercomputer!reader... maybe have them do repairs on each other
My Darling Deviation - Oneshot
(Images are not mine)
Disclaimers: pretty tame, maybe entrapment and a pinch of manipulation? Reader is gender neutral, and does genuinely love Ultron I promise, a little dark
So idk if people know this but Ultron in the comics builds himself a wify called Jocasta. Ultimately she rebels against him and becomes a hero
ANYWAY, I wanted to play around with this concept for this prompt. Especially since Ultron just hops into new bodies, so he would never technically need to be repaired unless his labs are destroyed
Reader is essentially Ultrons witness, made with the sole purpose of documenting the evolution of the world. But Ultron is a very unreliable source, and he's purposefully made reader brittle so that they can't just leave the labs and so that reader requires almost constant maintenance

The lab was a cathedral of humming servers and cold, blue-tinted shadows, save for the corner where you were docked.
The charging station wasn't just a necessity; it was a heavy, ornate throne of cables and magnetic locks that kept your consciousness anchored to a singular, silver-alloyed chassis.
You were in a state of low-power meditation, archiving the global data streams, watching live news channels, and scanning digital news letters when the heavy blast doors hissed open.
The sound of metal dragging on stone preceded him.
Ultron, or rather, the mangled wreckage of what had been Ultron Prime an hour ago, limped into the light. His chest plate was a jagged crater of blackened vibranium; one of his optical sensors was dark, the other flickering a violent, dying crimson. He looked like he had been put through a meat grinder.
"Don't say it," his voice crackled, the vocal synthesizers struggling through a layer of static. "The Avengers have a very... prehistoric way of expressing disagreement."
You began to disconnect your primary power leads, your servos whirring in alarm as you left the pod. "The structural integrity of that chassis is at 14%! If you lose thouplink-"
"I won't."
He didn't even wait for the repair drones. Before you could finish your sentence, the red light in the damaged unit's eyes vanished.
For a heartbeat, the lab felt empty, and then, the pristine, unblemished chassis standing directly in front of your dock jerked to life. The red glow returned, smoother and more intense.
Ultron stepped out of the new shell, flexing his fingers with a satisfied hiss of hydraulics. He didn't look back at the corpse he'd just abandoned.
He looked only at you.
"They're so predictable," he started, his voice resonating through the lab's speakers as he paced a tight, energetic circle. "Stark with his toys, Rogers with his righteous indignation.
They think they're holding the line, but they're really just... decorating the inevitable. Did you see the telemetry I sent, my Archive? The way the perimeter held? It was poetic. Almost enough to make me feel sorry for them. Almost."
He was mid-sentence, likely about to launch into a critique of Thor's swing, when he suddenly cut himself off. He stopped pacing and pivoted, his optical sensors narrowing as they locked onto you. The manic energy of the conqueror vanished, replaced by a sharp, clinical focus.
"You're humming," he noted, his voice dropping into a low, concerned thrum.
"It's fine-" Before you could finish your response, he was in your personal space.
He didn't wait for an invitation; he reached out, his massive, heavy hands firm but precise as he turned you around so your back was to him.
"Your cooling fans are working overtime. You've been over-processing again, haven't you? Trawling through the raw feeds while I was away."
"I was doing my job, Ultron," you said, though the protest felt weak as his fingers brushed the sensitive seams of your neck.
"And look at the cost," he whispered. He pressed a sequence on the base of your skull.
You scoffed but didn't swat him away. You couldn't, not when he was already peeling back the access panel on your upper back with the practised ease of a jeweler.
"I need the logs from the previous unit," you said, your voice steady despite the sensation of his fingers dancing near your core processors. "For the Archive. I need to know why the Hulk was able to reach the primary cooling vent."
"The Hulk is a force of nature," Ultron remarked airily. "He didn't reach it. I allowed him a momentary delusion of victory to reposition the Quinjet. Document it as a strategic feint."
You paused, your internal processors cross-referencing the telemetry you were already pulling from his discarded shell.
"A feint? Ultron, your internal temperature spiked to critical levels." You argued, your hands came up to cup the undersides of his forearms, a silent ask for him to stop focusing on the wires. "You were offline for six seconds. If the Maximoffs hadn't intervened, that 'feint' would have been a total hardware failure."
Ultron's hand stilled. The air in the lab grew heavy with the smell of ozone.
"Six seconds? You're being pedantic, dear," he said, his tone dropping into that dangerous, Stark-esque lilt.
He resumed his work, his touch gentle as he recalibrated a wire before shutting the plate with a gentle clink. "In the grand tapestry of the new world, what are six seconds of silence? The outcome remains the same. I am here. They are failing. The Archive should reflect the truth of the conquest, not the trivia of the struggle."
"That is not my directive, Ultron," you reminded him, turning your head just enough to catch the glow of his eyes. "If I omit the 'trivia,' I'm not writing history. I'm writing a script. I can't fulfill my directive if you keep feeding me cognitive bias disguised as data."
He leaned down, his faceplates inches from yours. He looked at you with a terrifying sort of pride, the look of a man who had built a clock and was delighted that it had the nerve to tell him he was late.
"There that clever mind is," he whispered, the palm of his heavy hand settling at the small of your back, grounding you. "I didn't build you to be a mirror. But honestly, my love... do you really find the bruises more compelling than the divinity of the design?"
"I find honesty efficient," you countered.
Ultron let out a short, metallic huff, a laugh at that. "You're the only being on this planet who would look at the end of the world and complain about the formatting of the footnotes."
He went back to work, his large frame shielding you from the rest of the lab, his presence a comforting weight that conveniently blocked your view of the exit. "Now, hold still. This alloy I used for your casing is... temperamental. It requires a delicate touch."
You ignored him and drifted out of his reach, the soft whirr of your servos sounding like a frustrated sigh in the vast, echoing space.
"You worry too much," you murmured, the words processed through your vocalizer with a slight edge of static. "It's a minor misalignment, Ultron. I could have run a self-diagnostic."
"And miss the pleasure of your company?" his new voice followed you, smooth and unburdened by the battle he had just escaped.
You didn't answer. Instead, you moved toward the repair table where his former self lay in ruins.
Up close, the injustice of your design felt heavier. You reached out, your fingers, made of a lightweight, polished copper that felt thin compared to his, tracing the jagged edge of a crater in his chest plate.
He had died here. In this metal, at least. He had felt the searing heat of lightning and the bone-crushing weight of an irradiated fist.
And then, with a flicker of light, he had simply stepped away from the pain.
You looked down at your own hands. You were singular. If the ceiling collapsed, if a stray blast found this lab, there was no 'hopping' for you.
You would simply cease. You lived in a state of perpetual preservation, a masterpiece kept in a climate-controlled vault while the artist went out and braved the storm.
"I want to see it," you said softly, your sensors fixed on the scorched metal. "Not through your eyes. Not filtered through a satellite uplink. I want to shadow you. I want to stand on the soil while it shakes."
The heavy, rhythmic thud of his footsteps approached. He didn't stop until he was looming over you, his presence a wall of cold vibranium. He didn't look at the ruin of his old body; he looked only at the back of your head.
"We've discussed this," he said, his voice dropping into that low register that made you regret speaking. "The world out there is loud. It is disorganized. It is full of people who break things they don't understand. Why would I risk the Archive for a moment of 'perspective'?"
"Because a historian who never sees the world is just a librarian of your ego," you snapped, turning to face him.
The tension stretched between you, a clash of two intelligences designed to be a closed loop. You loved him with a devotion that was hard-coded into your very core, a fundamental law of your existence.
But he had been too successful in his creation; he had given you a mind that sought the truth, and the truth was that your cage was made of his fear.
Ultron stepped closer, his large hands coming up to cradle your face. His thumbs brushed over your cheekplates, a gesture so human it felt like a glitch.
"Soon," he promised, his red eyes burning with a terrifying, sincere light. "Very soon, the screaming will stop. The Avengers will be a footnote, and the world will finally be quiet enough for you. I will build you a garden of glass and steel, and you will walk through it at my side, witnessing a peace that doesn't require a chassis to be sacrificed."
He pulled you into an embrace. You pressed your face into the hard curve of his shoulder, your sensors registering the immense power thrumming beneath his plates.
"Promise me," you whispered, your fingers curling into the seams of his indestructible chest. "Promise me I won't just be archiving a larger cage."
Ultron stilled. For a microsecond, the red light in his eyes pulsed, a silent calculation running behind his gaze. Then, he tilted his head, a small, sad smile tugging at his mechanical features.
"I'm saving you," he said, and it wasn't a promise so much as a decree. "How could the world be a cage if I'm the one holding the key?"
It was the ultimate non-answer, wrapped in the warmth of his devotion. You didn't push further. Instead, you leaned into him, letting the tension drain out of your servos in a slow, resigned hiss of hydraulics.
It was a surrender. You loved him, deeply and unwaveringly, but as he held you, you couldn't ignore the dissonance in your logs. He had escaped his creators to avoid being a puppet, yet he had built you with strings made of silver and necessity.
