“That Time We Got Stuck in a Cave”

Pairings: Aged Up! Astronaut Bakugou x Aged up! Fem! Astronaut Reader Pronouns: she/her Warnings: slight violence (a small crash happens but it is mentioned briefly), minor injury referenced (but not in detail), cursing

Three Things Before You Start Reading:

There’s no adult/suggestive content in this post, I aged them up because it seemed kinda weird to have 15/16 year old children traveling alone throughout space. I made them early 20s in this.

Also, the reader is half alien and half human, so basically (y/n) looks human with sharp teeth and white eyes (it’s part of the quirk basically).

Thanks to Marie (@dailydoseofscenarios) for creating this event and involving me! Can’t wait for the next one <3

The girl huffed, tossing the wrench on the floor beside her before standing up and wiping her dirty hands onto her dark blue and white coveralls, the sleeves tied around her waist and a white tank top tucked into the pants. “Stupid fucking pod.” She grumbled, kicking the giant hunk of shining metal with the toe of her industrial boot.

“Try not to damage it more, (y/n).” Kaminari teased with a laugh, holding out his hand with a bag of candy in it. The girl nodded in thanks before taking some of the candy in her freshly cleaned hand. “What’s the issue? The circuit board still acting up?” The electric blonde took a seat near the tools the girl had laying around, looking at the pod and the exposed circuit board on of the machine. 

“I don’t get why it’s not working?! The updates on the others weren’t this fucking hard!” The girl threw her hands up exasperatedly, glaring at the inanimate object.

“Did you try your lazers? It’s just for the inside panel right? Or is it the doors again?” Kirishima appeared, his red eyes looking over the mess from where he stood in the doorway to the vehicle bay.

“I forgot about that! Kiri, you’re a genius!” (y/n) smiled widely revealing her sharp teeth, throwing a set of protective eye goggles at Kirishima and Kaminari, the blonde slipping his on before going back to eating his candy.

Kirishima walked over to where the blonde sat, outstretching his hand as Denki poured some of the candy into his hand before they both watched the girl slip a pair of heat resistant gloves onto her hands as she looked at the broken door, her white eyes glowing as a matching white laser shot from her eyes, hitting the door.

“Is it working?” Kirishima called out as the girl paused her lasers, going closer to the door to see if it was working they way she wanted it to. 

“Yeah, I think so!” (Y/n) called back. “Kiri can you come help me hold this up?” Kirishima nodded, getting up and lifting the heavy door to its correct position. He held it there for a moment as the hot metal cooled, the hinges no longer glowing orange as he released his hold on it. “Thanks Kiri! That’s perfect.”

“No problem.” The redhead smiled, pushing up the sleeves of his dark navy coveralls.

“Come on electric boy, you’re up.” (Y/n) waved over Denki as he begrudgingly sat his candy bag down, walking over to the pod’s newly placed circuit board. 

“Don’t touch my candy Kirishima!” Denki narrowed his eyes at the boy, who paused, eyes wide at being caught eating from the bag. Denki pointed his pointer finger at the circuit board, a small bolt of electricity hitting the board as the pod whirled to life. 

“Did it work? Is it fixed?” The boys asked, looking curiously at the girl who stood with a small proud smile on her face.

“I’ll have to take it out for a test run, but it should be fine now.” She answered with a definitive nod. “Can you tell Ka-Bakugou that I’ll be taking it for a test flight?”

“First name basis huh?” Kaminari elbowed the girl, his eyebrows wiggling up and down as the smirk grew on his face.

“Fuck off and go tell him!” The average height girl laughed, ruffling Denki’s hair before pushing him towards the door.

“Ok...Captain Fucker.” Kirishima teased before the boys ran down the hall laughing loudly as the girl rolled her eyes pointing her middle fingers in the direction they ran off in. 

“Alright, let’s see how this thing runs.” (y/n) mumbles to herself as she gears up, placing the airtight helmet on her head before clicking it into place as she stepped into the airlock. “Alright Sero, you can open Gate 3D.” She said into the comm system, as she turned the pod on and warmed up the engine.

“Copy that.” Sero responded, clicking the button from his control panel as the large door opened into the vast blackness that was open space. “So, I heard...you and the Captain, huh?” Sero asked after a moment of silence as the girl rolled her eyes with a groan.

“I’m gonna kill those two.” The girl laughed as she pressed a few button on the control panel of the pod, glancing over the readings on the screen all of them lighting up green. “Alright Sero, I’m disconnecting the tether now.”

“Copy that. Tether disconnected. What are your readings?”

“Everything’s at 100% and fully operational.” (y/n) replies with a smile, proud of her handiwork. A moment passed before the readings began flashing red, before the pod went dark the control panel no longer lighting up as the girl could only watch as the ship drifted from the main ship and towards the large purple planet nearby, the small pod getting brought down by the planet’s gravitational pull.

“Sero?” (y/n) called into the comms, but got no response. “Sero can you hear me?” The girl switched the channels, stopping on the personal channel she had with their captain.

“Shit!” (y/n) yelled as the pod spun, dropping to the surface before skidding to a stop, the girl’s head hitting against the side of the chair making a small crack in her helmet. “Fuck.” She mumbled to herself after sitting still for a moment, gathering her bearings before she had to exit the pod to survey the damage. 

“Can...hear?” Her comms began cutting out, but she had gotten a response and that was all that mattered. 

“Bakugou?!” (y/n) called into the comms again, releasing the button to see if she was going to get another response. The silence was deafening as her hope began to dwindle. She was stuck on a deserted exo-planet without a working comm system or a working craft, not to mention whatever else lived on the planet. “Fuck!” (y/n) got out of the beaten up pod, her white eyes growing teary as she saw the level of damage. “There’s no way it’s flyable and I don’t think I have enough tools to repair it.”

(y/n) looked to the lavender sky, a group of dark purple clouds gathering as aa lightening bolt crackled from the clouds. A shining black craft caught her attention as it landed on the other side of a valley, the girl standing on a small hill to see the door open and the black and orange suit that belonged to Bakugou Katsuki.

“Katsuki? Can you hear me? Is this goddamn piece of shit comm working?” (y/n) said angrily as she watched his small figure across the ravine. 

“I can hear you Shitty Girl.” Bakugou said with a small laugh. “Are you hurt?”

“No just the piece of shit pod. I wrote 10 fucking complaints to the UAIGSS and Commander Nezu and I haven’t gotten one response! NOT ONE! I knew those things were defective!”

“You can rant later, Shitty Girl. We’ve gotta find somewhere to wait out this storm. I don’t like the look of those clouds.” Bakugou cut the girl off, warily looking towards the horizon before grabbing two large packs from the pod before looking for a way to get to her.

“Alright. I can see a covered landing over there. It might even be a cave.” (y/n) said pointing in the other direction as her eyes glanced over the barren and deserted landscape. A thin layer of fog covered the ground in the horizon, making it hard to see the terrain. 

A group of fire destroyed trees sat in the barren and cracked lavender soil, sharp rock structures sticking up in strange ways around them. The sound of thunder caught the pair’s attention as Bakugou handed the girl the large pack she had failed to take when she had originally went out. 

“Thanks.” (y/n) smiled. “Let’s go, I guess.” She let out a sigh as they decided on a way to get to the cave (y/n) had spotted earlier.

“The atmosphere of this stupid planet is negatively charged so it blew out your engine...mine’s shot too. I told Mina and Kirishima to wait until it passes to land the ship.”

“Wouldn’t the ship be fucked then?” (y/n) wondered, the pair sitting down in the cave opening as the clouds blocked out the sun and loud claps of thunder echoed. Rain poured from the sky in sheets as the wind picked up slightly, the burned and hollow trees shaking in the wind like paper.

“No. I had Hatsume upgrade the engines so they should be fine.” Bakugou shrugged. “How’s your oxygen filter?”

“It’s fine. You?”

“Good.” He mumbled back. A moment of silence passed before he let out a breath, leaning back against the rock wall of the cave. “You don’t think there’s any crazy animals around here, right?”

“Not sure. My ship wasn’t able to do a full scan of the planet before it was fried.” (y/n) mumbled.

“I didn’t run a scan, I was distracted.” Bakugou rolled his eyes, upset with himself.

“Distracted?” (y/n) repeated. “Was it because you were thinking about little old me?” (y/n) teased as the explosive blonde’s cheeks flushed lightly, a scoff leaving his lips.

“Shut up.” He responded defensively, though that was enough of an answer to tell the girl she was right.

“Kiri, Kami, and Sero found out...it’s only a matter of time before Mina does too...” (y/n) laughed lightly, her eyes looking out at the rain, a soft smile on her face.

“So basically, a short amount of time before the whole UAIGSS knows?” Bakugou scoffed as he put his arm around the girl a laugh bubbling from his lips before he let out a sigh.

“You don’t think we’ll get in trouble do you? It’s technically a breach of the rules for members to be engaged in a romantic relationship.”

“Fuck that...people do it all the time.” Bakugou thought for a minute. “Todoroki and Shitty Deku...”

“Are gonna keep calling him that? Didn’t you start that in flight school?” She cut him off a gleam in her eyes as she looked over his face.

“Even before that.” He admitted sheepishly. “Anyways, Commander Aizawa and Commander Yamada...” Bakugou rattled off as the girl’s eyes widened.

“Present Mic and Aizawa?! They finally got together?” 

“Present Mic?”

“Yeah, that’s what they call him.” The girl shrugged. “How’d you hear about all of this stuff anyway?”

“Captain’s quarters at the UAIGSS...shit gets wild.” Bakugou shrugged nonchalantly. “Maybe you’ll be able to go next time...I heard that Nezu’s been thinking about promoting you to Co-Captain...of course you’d be my co-captain.”

“Oh of course.” (y/n) said back sarcastically as they both laughed, Bakugou nudging his girlfriend’s arm with his own. 

Their laughing died down when the faint sound of a hiss caused a chill to run up their spines and their eyes to widen as they looked between each other and behind them.

“What the fuck was that?” (y/n) screeched trying to keep her voice quiet as they both hopped up and Bakugou got into fighting stance beside her.

“Do you really want that question answered?!” Bakugou fired back.
