The colony should have been empty.
That was the whole reason the team had been sent.
The briefing room aboard the Watchtower was unusually crowded when you arrived. Tim stood at the front beside a holographic display while Batman remained near the back wall, silent as always.
A rotating image of a distant planet hovered above the table.
Tim tapped a control, the image zoomed inward, and an abandoned settlement appeared.
"Three days ago," Tim began, "a League deep-space probe detected artificial structures on an uncharted world near the edge of explored space."
The hologram shifted again to reveal rows of metallic buildings appeared, roadways, towers, an entire city.
Bart leaned forward.
"So we're doing archaeology now?"
"No," Tim replied. "We're investigating why a supposedly abandoned colony suddenly started transmitting power signatures."
That got everyone's attention.
Cassie frowned. "Someone's living there?"
"We don't know."
Jaime crossed his arms. "No distress signals?"
"None."
"No ships?"
"None."
"That's not suspicious at all."
Tim ignored him and continued, "The colony predates most modern galactic records. League databases couldn't even identify it."
You glanced up at the hologram, something about the architecture felt familiar, not enough to place it, just enough to make the back of your neck itch.
Batman finally spoke, "If anything appears unusual, report it immediately. Do not separate from the team."
Bart groaned. "Why does he always say that right before things go horribly wrong?"
The ride to the colony took several hours.
The Bio-Ship drifted silently through space while everyone occupied themselves, Bart was playing a game on his phone., Cassie was reading mission files, Jaime was arguing with Khaji-Da all while Tim was reviewing maps.
You sat near one of the observation windows, watching stars streak past, with Conner eventually dropping into the seat beside you.
"You've been quiet."
You shrugged.
"Just thinking."
"About?"
"The colony."
Conner glanced toward the mission files,"You know something?"
"No."
You hesitated, "Maybe."
That earned his attention.
"The architecture looked familiar."
"How familiar?"
You frowned, "I don't know."
The answer bothered you.
Kryptonian memory wasn't perfect, but you usually remembered things your dad taught you. This felt like trying to remember a dream, close enough to touch, too far away to grasp. Before you could think about it further, Bio-Ship's voice echoed through the cabin.
"Approaching destination."
Everyone immediately sat up.
Tim stood, "Alright, team. Let's work. We don't need traditional oxygen masks because there's a breathable atmosphere, but the air's dense so keep your rebreathers on, Superboy, Supergirl, you're exempt."
The colony should have been empty, instead, it felt more like a graveyard.
The Bio-Ship landed in the centre of the settlement with a low hum, the ramp lowered and cold wind rushed inside, making you shiver.
Tim stepped out first, the rest of you followed, the only thing that greeted you was silence. The settlement stretched endlessly across the landscape, metallic structures rose from the dark terrain, dust drifted through empty streets. No lights, no movement, no signs of life.
Bart rubbed his hands together from the cold.
"Creepy."
"Very descriptive," Tim said.
"I'm serious. This place looks haunted."
You were about to make fun of him when your gaze landed on one of the nearby buildings. Then another, then another.
Your stomach dropped. "No way."
Cassie glanced over. "What?"
You pointed toward a series of symbols etched into a nearby wall, "I know that language." The team immediately turned toward you.
Jaime frowned. "You do?"
Slowly, you approached the markings. Your pulse quickened, you'd seen them before. Not in person, but your father had shown you enough Kryptonian texts growing up.
Stories, historical records, maps, lessons about a world that no longer existed. You recognised the symbols instantly.
"It's Kryptonian." The silence that followed was immediate.
Tim's expression sharpened. "You're sure?"
"Yeah." You swallowed. "I'm pretty sure. It's not Phaelosian, or from Planet Daxam, it could be another offshoot but I'm certain the origin is Kryptonian. "
Suddenly the colony felt much less abandoned, and much more personal.
The team spent the next hour investigating, most of the settlement appeared untouched, there were no signs of battle. No signs of evacuation, no signs of disaster.
Just...nothing.
Entire buildings stood frozen in time, equipment remained where it had been left, personal belongings sat abandoned, it looked as though everyone had vanished in the middle of their day. You found children's toys, family photographs, records written in Kryptonian, a civilisation preserved in a single moment.
The deeper you explored, the stranger things became, organic growths crawled across walls and ceilings, dark tendrils spread beneath metallic surfaces. Vein-like structures pulsed beneath the colony itself.
Alive, growing, watching.
Jaime scanned one of them, followed by his visor lighting up.
"Definitely biological."
"That's reassuring," Bart muttered.
"It wasn't meant to be."
The first scream echoed through the colony moments later.
Everyone froze.
Tim reacted instantly.
"Look out!"
The wall beside you exploded. Metal and debris erupted outward, and a massive creature burst through the structure.
Then another, then three more. The colony erupted into chaos, the creatures moved like predators, not animals but hunters.
Their bodies were covered in thick armoured plating, multiple eyes tracked movement simultaneously, their claws carved through metal like paper.
One lunged directly at Bart, he vanished in a yellow blur. Another slammed into Cassie. She caught it midair and hurled it through a building, with the impact shattering half the structure.
You launched yourself skyward, heat vision erupted from your eyes, the beam struck one creature directly in the chest. It barely slowed down.
"What?!"
The thing roared, then jumped, like actually jumped, thirty feet straight into the air.
Its claws scraped across your shoulder before Conner intercepted it, the two crashed through a nearby tower. The ground shook, everywhere you looked the fight intensified.
Jaime's cannons lit up the colony, Bart became a streak of yellow lightning. Cassie punched one creature hard enough to send it flying across the city. You grabbed another by the throat and drove it through three separate walls.
The creature shrieked, its tail whipping wildly, then another creature appeared behind you, too fast. Its claws raked across your side, whilst it didn't cut you, the force of it hurt like a bitch.
You retaliated immediately, your punch shattered its armoured skull. The body collapsed, yet more kept coming. They emerged from underground tunnels, from buildings, from hidden nests buried beneath the colony, dozens upon dozens.
The fight stretched on for nearly twenty minutes and by the end, the streets looked like a war zone. Broken structures, cracked pavement, creature corpses everywhere.
Eventually the battle turned, the creatures began falling one by one. Until only a single survivor remained, its body lay broken across the colony floor.
Breathing heavily, dying. You approached carefully.
Conner moved beside you.
"Think that's all of them?" Bart asked.
"Hopefully."
The creature twitched, then its tail lashed outward. Pain exploded through your calf, you screamed as the barb punched straight through your leg. For a split second it felt like molten metal had been driven into your flesh.
Then the tail ripped free, you stumbled backward, the world tilted.
Conner caught you before you hit the ground.
"Y/N!"
Your entire leg burned, not normal pain but something deeper. You looked down, the wound itself wasn't severe, just a puncture, already healing. At least, it should have been.
Instead the flesh around it remained red and raw and irritated. It was burning, like poison spreading beneath your skin.
"I'm fine," you managed.
Conner didn't believe you, neither did Tim.
"Let's head out, we've got our data, we know where the signatures were coming from. We're going to analyse the rest of the colony upon arrival at the Watch Tower, and if we ever come back, we'll need reinforcements."
So the team boarded the Bio-Ship and headed home.
For the first fifteen minutes everything seemed normal.
Then the pain returned. It started in your leg, a deep ache spreading upwards Your muscles felt heavy and your thoughts sluggish, a strange exhaustion settling over you. You sat down hard in one of the Bio-Ship seats.
Conner noticed immediately.
"You okay?"
"Yeah."
"You don't sound okay."
"I'm fine."
Cassie appeared from her seat.
"You look awful."
"Wow. Thanks."
"No, seriously."
You frowned, something felt wrong. You stood, or tried to because your balance immediately wavered.
Conner grabbed your arm,"Easy."
"I'm okay." You pulled away.
Then you tried to fly,yet nothing happened, causing you to freeze.
Conner noticed. "What?"
You stared at him.
Then pushed off the floor again. Nothing.
No lift, no instinctive pull, no effortless weightlessness. Just fricking gravity. (insert Kenma's gravity speech lmaoooo)
Your stomach dropped. "No."
"What?"
You tried again, nothing. Panic began creeping into your chest. "No no no." (Obsession type shit lmao)
Cassie stood. "Y/N?"
"I can't fly."
Silence filled the cabin. You looked around, everyone stared, "I can't fly."
The words sounded ridiculous, impossible even. You were Kryptonian, flying wasn't something you thought about, It was like breathing, and suddenly it was gone.
Tim immediately moved closer. "What do you mean you can't fly?"
"I mean I can't fly."
Fear settled over the cabin, because powers didn't just disappear, not for Kryptonians, not without a reason. Slowly, you pulled up the leg of your suit. Dark silver veins stretched from the wound which had begun to fester, branching beneath your skin, moving upward, growing.
"What the hell?" Bart whispered, even Tim looked alarmed.
You stared at the veins, then watched them spread another centimetre.
Tim immediately opened a communications channel. "Robin to Watchtower."
Static crackled. Then Cyborg's voice answered.
"Go ahead."
Tim's eyes never left you. "We need medical personnel waiting in Hangar Three."
"What's the situation?"
Tim hesitated, for the first time all mission.
"Supergirl's injured."
The ride back felt endless.
The veins continued spreading, the pain only worsening.
Your hearing flickered occasionally, your strength felt inconsistent, your waterline grew teary and you began to sweat profusely, breathing got harder, holding your head up got harder. Every symptom made the cabin quieter, more tense.
Nobody joked anymore, nobody talked much.
Conner stayed beside you the entire trip, a hand resting around you as you laid your head on his shoulder, as though he was afraid you'd disappear if he let go. By the time the Bio-Ship entered Watchtower airspace, standing felt difficult, like your body wasn't listening anymore.
The hangar doors opened before the ship had fully landed, heroes were already waiting.
Nightwing, Flash, Black Canary. Several League medics. Batman stood further back, cape draped around his shoulders.
And Jason.
You almost missed him.
Leaning against the far wall in his Red Hood gear, arms crossed.
"When does he ever come around here?" You think to yourself in a daze
The second he saw you being helped down the ramp, he straightened, every trace of casual indifference vanishing. The moment they saw you, concern spread through the crowd.
Conner helped you down the ramp. You hated that. You hated needing help. You took two steps, then your vision blurred. A violent cough tore through your chest. You doubled over.
Something warm splattered across your hand. For a second, your brain didn't process it. Then you looked down.
It was blood. Bright red blood.
The hangar went silent.
Another cough hit, harder this time, blood spraying across the floor.
"Y/N!" Someone shouted your name but you struggled to make out who.
Your nose started bleeding next, not a trickle or a drip, but a steady stream. Panic erupted instantly.
You felt your eyes getting teary again but instead of water, blood escaped your waterline. The throbbing pain in your calf was so concentrated that your next step had your leg giving out.
In your daze, you'd thought you'd pass out before you hit the floor, but someone caught you.
Jason.
One second he was across the hangar, the next he was kneeling in front of you. His hands cupped your face. "Hey. Hey, look at me."
You blinked through the dizziness.
"Jace..."
His expression was terrifying, the absence of his helmet makes him look so much less threatening in your opinion. He wasn't angry or annoyed. But he was scared, actually scared.
"Stay with me." Another cough wracked your body, blood stained the "S" symbol of your suit. Jason swore viciously.
"Move!" he barked at the crowd. The command snapped everyone into motion.
Nightwing reached your side, Flash disappeared and reappeared with medical equipment. Batman was already moving.
But Jason never let go of you.
One hand remained locked around yours, the other pressed against your shoulder. Grounding you, keeping you upright, as if sheer stubbornness could stop whatever was happening.
"You're okay," he said. The lie sounded desperate.
"You hear me? You're okay." Jason held you before your eyes shut.
The last thing you saw before everything went dark was him shouting for the medics.
When you woke again, to say you felt like shit would've been the understatement of the century.
Your mouth parched, your eyelids heavy with fatigue, the tightening in your chest was sharp, and combined with the tautness of your muscles, you could barely move. The throbbing, hot sensation in your calf felt stronger, and your head continued to pound.
Arguably, the worst part of it all was that this was so foreign to you.
Being half-Kryptonian, you had never experienced human illnesses, so you being so severely sick gutted you in a way you couldn't describe.
The way you felt wasn't the only difference, the room was different too.
White, quiet, contained. The first thing you noticed, after fighting a wave of nausea, was the glass, thick and reinforced.
The second was your mother. Lois sat beside your bed, her hand wrapped around yours. The relief on her face nearly made you cry.
"Mom?" Lois immediately stood to give you a hug.
"Hey, honey." Your throat felt raw.
"What happened?" Her smile faltered slightly.
The answer came from the observation glass. Clark stood on the opposite side alongside your little brother Jon, and Kara. All separated from you, unable to enter, then you noticed someone else. Jason, still there, like he'd never left.
"What happened?" This time your voice cracked.
Lois squeezed your hand. "You're sick baby."
"Doesn't answer my question." You joked
"That disease you contracted is Kryptonian." Silence.
"Meaning?" You didn't know why you even asked that, you knew what she meant.
"It only infects Kryptonians." Despite, knowing what she was going to say , the room suddenly felt colder.
Outside the glass, Clark looked helpless, and that scared you more than the virus ever could, because your dad always knew what to do. Except now, he couldn't even sit beside his daughter.
"Where's Conner?" You asked, noticing his absence.
"Bruce—Batman, suggested he be put on observation, he was in close contact with you and they still don't know how the disease spreads, they don't know if he could be infected, but from the looks of it he's okay."
"How long have you been here? You don't get off work till 6'oclock today—wait what time is it?"
"Only a couple hours baby, Perry let me go early after I told him you had an accident." Your mother responded
"You made me sound like a baby." You complained.
"You are my baby." She laughed
"They made me go through several decontamination chambers before coming in here, I'll probably have to go through those again eugh."
" Gonna ruin your hair?" You asked.
"You bet." You could hear the smile in her voice without even looking at her
The following days blurred together. Your powers began failing one by one. Flight disappeared first, your heat vision followed. Then your strength, then your hearing. The world grew quieter, smaller, scarier.
The hemorrhaging came and went. Some days it was nosebleeds, other days it was coughing up blood so severe the medical alarms went off. Every episode left the Watchtower and your family shake, and every single time, when you looked through the observation window afterward, Jason was there.
Sometimes standing beside Dick. Sometimes arguing with Bruce. Sometimes asleep in a chair because he refused to go home.
Outside your room, the Watchtower became a war room. Barry practically lived in the laboratory, with Bruce working beside him.
Dr. Leslie Thompkins joined the effort. Mr. Terrific, Cyborg, and every scientific mind available contributed.
The virus had originated from the colony itself—an ancient Kryptonian pathogen. Something engineered long ago to target Kryptonian biology specifically (Thaedus vs Viltrum type shit ok im sorry i'll stop)
A weapon, one that should have stayed buried, and it was killing you from the inside out.
Jason took it worse than most people realised, maybe because nobody knew exactly what the two of you were, and ever since the fallout between you guys because you found out about his fling with Rose Wilson, of all people, he'd never had the chance to apologise, and it took you being on your deathbed for him to come to that conclusion (potential fic idea 👀 send me thoughts guys)
And every time your condition worsened, he looked like he was being torn apart. After a particularly bad hemorrhage that left you unconscious, he asked to enter your room.
He couldn't bare to see you sick, how you, once so full of life was now wasting on a hospital bed, but he had to see you. Sure, he saw blood every night in Gotham, but you were different.
He walked through several of the decontamination chambers to get to you, all while holding a bouquet of your favourite flowers. The last time he bought you those were for your 15th birthday.
After sitting down beside you, he dropped the flowers by the bedside table, he never believed in any of that sentimental shit but he had a lot to say, but had no way to say it. All he could do, was be there, and hope and pray Barry would find a cure.
Although you weren't awake to see it, when Jason reached for your hand, this time, he didn't let go.

Debrief: in which your ex was a Manchild and their reactions to it
Case Notes: for an anon Request! Enjoy!
Dick Grayson
“He told me he couldn’t text me for three days because Mercury was in retrograde and his ‘communication energy was blocked.’ But he liked ten of my posts in that time.”
Dick’s jaw drops.
He’s the mix of older-brother disbelief and lowkey jealous boyfriend energy.
“Mercury was in—? No. No. You deserve an apology and a NASA-level excuse for that one.”
He’s dramatic about it too:
“I swear, Y/N, I’ve fought clowns and supervillains with more emotional intelligence.”
He will not stop bringing it up later — “Hey, Mercury’s clear today, want to actually be communicated with?”
Jason Todd
“He said he couldn’t come to my birthday dinner because it ‘conflicted with his self-care night.’ Which, by the way, was just him playing Call of Duty with his friends.”
Jason leans back, silent for a beat, then lets out the longest exhale.
“I would’ve gifted him a self-care night. Six feet under.”He’s visibly restraining himself,you can see the murderous twitch in his jaw.
Later, when he’s calmer, “You know what? You dodged a bullet. I’m just mad you didn’t let me fire one.”
Tim Drake
“He broke up with me because I didn’t ‘match his vibe’ anymore. Then texted me a week later asking for my HBO password.”
Tim looks up from his coffee like 😐.
“He WHAT?”
Cue the analyst in him going feral, “So he emotionally disconnected, then tried to mooch? That’s… statistically the worst combination of traits.”
Tim absolutely goes and changes all your passwords for you that night, muttering, “We’re not letting this idiot touch your login again.”
Roy Harper
“He told me he couldn’t commit because his fantasy football league was too emotionally demanding.”
Roy almost chokes on his drink.
“His WHAT now?!”
He’s laughing, but it’s the angry kind of laugh, “You were out here trying to build a life, and he was drafting quarterbacks for an imaginary team?”
He gets real soft after though, “his loss. You’re building a life with me now.”
Kyle Rayner
“He ghosted me, but still kept reposting my art on his story with ‘credit to the artist.’ Like— sir, I’m the artist. You know that. Text me back.”
Kyle winces so hard.
“That’s criminal behavior. Actual villain arc material.”
He’s both offended as an artist and as someone with taste.
“You mean he appreciated your talent but couldn’t appreciate you? Nah. Give me his handle. I’ll ‘accidentally’ roast him in my next Lantern construct.”
Wally West
“He told me he was ‘too busy working on himself’… then immediately started dating someone who looked exactly like me, but worse.”
Wally blinks.
“You’re telling me he wanted you— but with lag?”
He’s pacing, doing that fast-talking rant.
“See, that’s the thing. People say they’re working on themselves, but what they mean is ‘I don’t want to get called out for being lazy.’ You know what you deserve? Someone who actually wants to do the work with you.”
He’s blushing by the end of that speech, “but now I’ve got ya, babe. And we’re doing this life thing together.”
Garth
“He said I was ‘too emotional’ because I cried when my pet fish died. He said it was just a fish. HIS DOG’S NAME WAS KEVIN.”
Garth is offended on a spiritual level.
“That’s not ‘too emotional,’ that’s being human! Or… Atlantean. Whatever.”
He puts a hand on your shoulder, earnest and soft, “I would’ve held a funeral. With candles. And sea flowers. That’s what your fish deserved.”
You melt a little. This man gets it. He’s writing a eulogy in his head already.
Conner Kent
“He said he wanted a ‘low-maintenance’ girlfriend. But then he’d sulk for days if I didn’t text him good morning first.”
Kon groans and actually leans back like he’s in pain.
“I swear, some guys just want a mom, not a girlfriend.”
He’s looking at you with that boyish half-smile, “You shouldn’t have to raise your boyfriend.”
And when you laugh, he adds under his breath,
“Let me at least prove I can handle basic maintenance.”
Jaime Reyes
“He said I was ‘too intimidating’ because I have a career and opinions. And then he asked if I could help him fix his resume.”
Jaime bursts out laughing— then immediately stops.
“Wait. Wait. He insulted you and asked for help?”
Khaji-Da chimes in from the Scarab saying something that makes him smirk, “Khaji says ‘The male in question appears to lack basic self-awareness.’ And I agree! You want me to send him a ‘resume tip’? Like, ‘try growing a pair’?”
