Space Girl
She's out of this world and in his bed! Meet SuperNova, a humanoid alien who loves everything Earth has to offer. And she loves Mark just as much
Mark Grayson x Black! Alien! Reader
Warning: reader and mark break up and get back together, mentions of smut, it's kind of a long one, but all that aside I hope you enjoy and consider sending requests, leaving comments and likes! <3
Note: you're from a planet called Aurelix, it's a peaceful planet but its people are warriors with a gentle temperament. All the people from this planet have glowing eyes, it can be hidden with contacts. It's basically Earth with way better technology and everyone has powers. Also, you can fly and create burst of energy, your powers are cosmic control due to a genetic experiment and yeah that's it, that's all! Eve and Mark don't have feelings for each other here, man stealing is never the move guys
༻༺༻༺༻༺༻༺༻༺༻༺༻༺༻༺༻༺༻༺༻༺
For as often as he does it, Mark sometimes felt shame for flying. He felt shame for soaring through the air on a regular basis even though it was part of his genetic makeup. Biologically, he should fly. Logically, he should fly with no guilt. He trained to fly, he likes flying. It's more natural to him than walking sometimes. Yet he can never forget why he can fly. Why his body gave him the strength to destroy lives just as easily as he can save them.
At the end of each day, Mark was a Viltrumite. From a race of brutes who use that same flight to take over worlds and murder anyone who objects. No matter how human he was, Mark would always have something evil inside him. A cancer that no amount of treatment could cure.
That shame keeps him human, as much as he wished he didn't feel it. Others from different planet's didn't get it. Full humans definitely wouldn't get it. And you? You didn't even come close to understanding. Not without trying though.
Mark could never forget when he first saw you. It was warm out, nice and airy with just the right amount of breeze flowing. The house next door received new occupants and settled in quickly it seemed. From his bedroom window, which faced your backyard, he saw you.
Flying in a game of tag with your mother and father, chasing each other with water guns. None of that mattered. The sun caught your skin, which seemed to glow under the light and your curly hair was tied into a gorgeous bundle of mini twist that was then wrapped into a ponytail. Pieces escaped on your face, the rest moved behind you with each turn and twist you made against the backdrop of the cotton candy clouds.
Mark wasn't exactly super-duper careful about who saw him flying but he also wasn't flying around in circles with his dad in the backyard. Anyone could've seen but you didn't care. Infact, you laughed as your mother sprayed you in the face with water and you sprayed her back in response. Flying around care free without an ounce of shame or fear for doing something so natural to you. And for a split second he felt a hint of jealousy. You probably weren't from a race of blood thirsty killers.
As your mother and father grew tired, they floated gently back to the ground, and you made your way to the Earth. But not before you glanced his way. Glowing green eyes glanced into his bedroom window, and you smiled curtly before you landed on your feet and skipped inside with your mother and father gleefully chatting about dinner.
That was the first time Mark saw the good in being an alien in a while. He saw the good in flying about carefree, in feeling no shame about being what he is.
The next time he saw you, it was ringing his front doorbell.
It was a relatively quiet day. Mark went for a run, came home, took a nap, even had time to take a shit. His mother called him to get the door from where she was in the house, then he made his way down the steps.
Opening the door, he saw you. You, floating just a bit off the ground with your car keys in hand. You didn't know him. How would you feel if you knew? Knew he was a Viltrumite, knew what atrocities his "people" had committed. Of course you knew, if you were from space. Had they destroyed your home, that's why you came to Earth? Had-
"Hi! Driveway-uh. Your car..." You searched for the next words, still clearly attempting to get a grasp on English. Glancing out behind you, he looked. His mom accidentally blocked you into the driveway.
"Your car is...blocking? Blocking. My car." Despite how you struggled to get the words out, you still beamed with pride at how you were able to get the words out.
"Oh...sorry." He smiled at you, your dark hair made you look like a cherub. No longer in twist but instead manipulated into curls that framed your face and highlighted your beauty. By Earth and space features you were no doubt beautiful.
Awkward silence settled in between you two and you stopped smiling. Tilting your head you floated closer to him and before he knew it your hand was on his shoulder.
"You are sad?" His first instinct was to lie. It was to say no but... What could be the harm in being honest anyways?
"...Just a bit." Looking down at the ground he shrugged and ran his hand over the back of his neck.
"Why?" What, was your planet just filled with nosy Nancy's? But something in his heart pulled. You were from space. You didn't understand the intricacies of humans keeping to themselves yet. And maybe he just needed a listening ear.
"My dad. He did-...he died."
"You lie?"
"What?"
Just then, a woman down the street called your name, followed by speech in a different language. Anyone else would assume it was just a different language from Earth, but Mark knew better. It was of an entirely different language from an entirely different planet. Turning your head, you looked back to your house.
"Goodbye! Oh," You pointed behind you at the driveway and held up your keys. Should you even be driving on Earth?
"Car." You emphasized, shaking at your keys.
"I'll move it." He responded, finishing the thought for you. You smiled, dipped your head like a nod and flew off back to your house.
'You lie?' Your voice replayed in his head. There was no malice, no judging. You just knew. He lied. Someone knew he lied. And as uneasy as it should've made him feel, instead little waves of relief overtook him.
Before long, your English had improved by heaps and bounds. You were fully integrated into human society it seemed, except for your same blunt forward communication but it did little to stop you. For someone so new to Earth, you got hang of a social life pretty easy. Once you started wearing the dark brown contacts gifted to you by your aunt (who Mark later learned had moved to Earth years earlier) and stopped fighting your parents about them every day they finally let you masquerade as a normal girl from Earth.
By your second week at school, you were all anyone talked about. Well, you and...you. More specifically the appearance of the new hero SuperNova. Who was quickly taking over as Chicago's favorite alien superhero.
'Did you see her boots?'
'I need SuperNova to drop her curl routine.'
'She's cute or whatever.'
Flooded the hallways. Unlike most gossip though you flooded his brain. He typically didn't mind gossip. His parents taught him well enough to mind the business that pays him, but you were stuck in his brain. It didn't help that you two were teamed up together so often. And it didn't help that you and Eve were superhero besties. Or that you lived next door to one another, or that your mom and his mom were fast growing friends.
You were a great friend too. You understood him, but part of him was...uncomfortable. You seemed to just know. Everything in his brain, the tight knot of fears and anxieties in his stomach, you were even able to see the weight on his heart. And it made him so uncomfortable that you were more in touch with his feelings than he was.
So, he took to avoiding having actual conversations with you. Maybe not on purpose, perhaps on purpose he isn't fully sure. He knew virtually nothing about you personally. Not your likes, dislikes, foods you avoid and music you loved. Because if he knew, you'd be in his heart too. Along with all those icky feelings that cover him like a wet blanket you would be trapped in his heart. Those types of conversations could only lead to a deeper connection. A deeper friendship and some days Mark knew himself he would need more than that. It wasn't helpful that you were always stuck in his head, he didn't need you in his heart and soul too.
But you knew. Because you always knew. And your people do not believe in hiding feelings.
"Mark?" It was night, you two were flying home after a disturbance downtown.
"Hm?"
"You are scared that if we become closer friends, your true feelings will overtake you. You do not want to let anyone in because of the inherit shame you feel for who you are from and what you are. You are scared because you cannot hide from me. We do not have to be friends if I make you uncomfortable." With such flippancy you read him. Like it didn't matter, like you didn't unravel him with the efficiency of a well-trained therapist.
He literally felt sick. His palms began to sweat under his costume, and chills ran through his entire body. His stomach grumbled and felt like he swallowed a block of ice that was just sitting in his gut. His nervous system didn't know the difference between dealing with his emotions or being held at gunpoint. You kept flying home until you noticed he stopped behind you.
You stopped and slowly floated back to him. Eyes glowing, empty of hurt or malice but there was an underlying kindness. He had rejected you. He rejected getting to know you the way everyone else had, he rejected your friendship because he was afraid. But your eyes were like a door left open. You hadn't shut that door. It was still open for him; all he had to do was open it the rest of the way.
What, did you think you were saving him? That he was helplessly drowning in his own unnecessary shame that he's refusing to deal with while battling his growing crush on you? That he needed saving? Who did you think you were?
"You are fighting yourself. I bear no intention of 'bettering' you. I am saying what I have observed."
...Fuck, could you just get out of his head for two seconds so he could think? You totally didn't just provide him clarity. Definitely not. So why was he flying in the air completely stiff without saying a word?
"I'm hungry. I'm going to go home and eat. We do not have to be friends Mark. The choice is yours. If you are not comfortable with your feelings, then it must be frustrating for someone to try and help you understand before you are ready." You said, patting him lightly on the shoulder before flying away.
Leaving him alone to float over the city while he tried to shove his stupid feelings back down his throat. He wanted to throw them up. To scream out his frustrations and fears and regrets, and how he thinks you're really nice and smart and fun. But he couldn't. And he still couldn't stop thinking about you either.
༻༺༻༺༻༺༻༺༻༺༻༺
How he found himself at your bedroom window he doesn't know. He was in bed one moment, sneaking a glass of wine the next, then floating outside your window watching you slide open the glass and sit on the roof.
Then he was sitting next you on the roof. You were in pajamas, a matching bonnet corresponded with your fluffy robe and was the same color as your pajamas and bed slippers. He sat with you, knees pulled to his chest. The wind ghosted over his exposed feet. Somehow, he felt as if his heart was about to be as naked as his feet considering he didn't put on socks before he flew out of his window like a man possessed.
When would Mark Grayson ever hide from a girl he liked? Not that he only saw you as that. But here you were, kind and accepting. And he was fighting that and holding some fucked up resentment for you in his heart just a bit because he couldn't open up to someone. Not again.
Two aliens sat on the roof of a suburban home on Earth, looking up at the void of space. You were probably looking towards your home planet. Mark was looking for the courage to be honest. Because this wasn't just about you. Whether he wanted to admit it or not, he needed to open up to someone. Holding everything in was raising his blood pressure.
You didn't push him to speak. You were just happy he was there, you would've been happy without him. Why did it ease him just a bit to know that you could go on without him? Why was it so nice to not feel like someone is leaning on you with everything they have? More silence until Mark found the courage in one shiny star.
"My dad was actually on Earth in order to conquer it for the Viltrum empire. My entire life I thought Viltrumites were good. But the more I learn, the more I hear about the crimes. The planets they've fucked up, the lives they've destroyed. My dad never even cared about my mom. Since he left it's been up to me to defend Earth. I'm trying to balance everything, and I'm all Earth has left against Viltrum. He destroyed Chicago using my face, and he murdered the Guardians of the Globe, he lied for 20+ years to the entire planet, he tried to get me to join him and I'm just scared that Earth will see me as an extension of him but I'm human and I'm not like him at all I promise, Earth is my home and I just want to keep people safe and I'm not like the other Viltrumites-"
Soft hands covered his. While he talked, he began to spiral and didn't even realize how quickly he was drowning in his own thoughts. Didn't even realize that he was rambling so fast that he hadn't been speaking in sentences but just one long chain of thoughts. You interrupted the long rambling and saved him from sinking down into a dark place in his mind.
"I know."
"What?"
"My planet is not on your peoples list of planets to conquer. It is not possible Mark. We are not scared of Viltrum, we have never hidden or cowered before Viltrum. Our people are long standing enemies by Viltrum's choosing. You do not have to worry about me judging you for what you are. You do not have to explain you are different. I know you are different. If it will ease you, you can continue. But I want to know Mark. Not who you are not."
You did it again. You just swept him clean off his feet also basically just told him Viltrumites weren't shit to you. As if they were so insignificant to your people that Mark being one didn't even matter. Then again there always was a bigger fish.
"How come you aren't ashamed?" It was a genuine question. Mark carries the shame of being a Viltrumite every day that he prefers to keep it to himself. Leaning back on your arms you let out a chuckle and Mark buried his face in his arms that still rested on his knees.
"I have nothing to feel shame for. No matter my race, no matter how people view my species, I am me. I can't change that. I am who I am, I came from where I come from. I know me. And there is beauty in what I am."
A man and woman walked past kissing and giggling while a little girl hopped in front of them playing imaginary hopscotch, and a dog yipped excitedly between them.
You peered over the edge and motioned for Mark to come with you. Together two aliens watched three humans, and a dog partake in what to them was a small unimportant moment, but that little girl may remember this until she dies. In a thousand years would Mark even remember this conversation?
"Humans have such beautiful but short lives. And to them it isn't short, but to us it is. But we are all the same. I like TV, humans like TV. I like living, they like living. I make the most of my life, they make the most of theirs. Do they have time to spend worrying about what those before them of done? Or do they instead live for each day, focusing on what they can do with themselves now? Or do they focus on what they can do with their future knowing they cannot change the past?" Who told you to be so smart.
"A lot of us worry about the past."
"And if that is how you chose to live your lives then that is beautiful! But you do not have to let what other Viltrumites have done define you. You cannot change the past. But you can take steps to better your future. You can take steps to better your people. Or instead, better yourself but you are Mark. You are an...," You search for the word, eyes glancing up to the sky while you searched your brain
"individual! You are an individual and can make whatever choice you want. You can be the Viltrumite who changes things, or you can just be you. But you will be Mark for the next thousands of years you will be living. You do not want to carry shame for something you cannot change." It was like you just flipped on a light switch in his brain. Mark was ashamed over something he could not change. It would take time to go away but still. It can go away. That ugly feeling in his heart was finally able to go away and stop haunting him.
You pulled a blanket out from your bedroom window and tossed it over the two of you after a brush of wind ghosted you two. His feet no longer cold, and you covered his heart and eased his mind like the blanket.
༻༺༻༺༻༺༻༺༻༺༻༺
Having an alien girlfriend was a bit difficult. Mark has been attempting to adjust being open about his feelings, while he taught you the value of allowing him and others the luxury of not needing to talk through every feeling that comes through their heads.
After a few months though, something switched. And while Mark Grayson was flawed, he did know how to be a good boyfriend. But you had made things so easy by making it very clear how you felt at all times.
He knew when you were happy, when you were sad, angry, hungry, horny. You usually just told him. But today you flew into Guardians HQ with a proverbial cloud hovering over you and plopped down beside him with an uncharacteristic scowl. Your eyes were glowing so bright from whatever ailed you that it was like a spotlight beaming from your head, and for the life of him he couldn't figure out what was wrong.
Where you hungry? Tired? A headache? Were you perhaps coming down with something? Could you even get sick? Could he even get sick?
When five minutes passed without you even uttering a word to him, instead just scrolling on your phone and quickly sliding past certain post that seemed to increase your foul mood he realized it was probably best to ask.
"Baby?"
"Hm."
Ouch. Had you ever once scowled at him so hard? You've growled at him before; you've even bit him once on your cycle (or your version of it) but you've never made such a face at him. His pride was happy it was just the two of you in HQ after you both returned from separate missions.
You turned away from him on the couch you were seated on and hugged your knees closer to your chest.
"Are you mad at me?" Slowly he put a hand on your balled up form only for it to be shrugged off. You were so pissed you didn't even want him touching you.
More silence. He heard you shuffle then you straightened out and floated off of the couch. His eyes followed you upwards towards the sky. Hands on your hips, your eyes glowing down at him with tears brimming in your eyes.
"Why did you not tell me you wanted to break up?"
"...I don't want to break up!" The moment it sunk in Mark was floating in the air infront of you. You refused to meet his gaze, arms crossed and turning away from him. You went backwards in an attempt to create distance and Mark found himself floating forwards in an attempt to lessen the distance between you two.
"What's going on? Baby?" His nervous system couldn't tell the difference between you saying that and being shot. The air felt cold and heavy and the nerves in his stomach made him have to shit. You were still refusing to look at him as his hands searched for you while you dodged.
"You do not care about me. You do not care about us."
"Of course I care about you. Of course I care about us!"
"You have a very amusing way of showing it." You shoved him back, as if you just noticed how close he had gotten to you despite your avoidance. A streak of light remained as you flew out of one of the open windows. Dammit, why did they always leave windows open for their flying heroes? Although it was helpful Mark, didn't need it when his girlfriend was talking about breaking up with him and using those open windows to escape him.
By the time he flew out of the window to see if he could convince you to talk about this, you were long gone. The telltale streak of color the remains when you fly was even gone from the sky.
By the time he got home, and talked to his mom it was well past dinner time. Usually, you'd be heading home to eat with your family like you always do on a weeknight. Or you'd be flying home together like you often do late at night because that's when evil seems to emerge. Instead, there was no you.
You weren't cuddled beside him; you weren't conversing with him about the first season of Seance Dog that he was trying not to spoil for you, you two weren't holding hands in a comfortable silence, you weren't there for him to playfully tease or for him to excitedly ramble at.
Once again, he found himself at your window. Well actually your front door. Your window was locked, curtains drawn. A message, telling him to piss off, a saying you enjoyed since you learned it. He thinks your love of swearing is adorable, no matter how many times you say 'motherfucker' in a day. But he couldn't just let you think he didn't care. If he didn't care, he'd be at home fast asleep.
He settled for the old fashioned way. He rang your doorbell and waited with baited breath for someone to open the door. Instead, your mother opened the door and stood towering over Mark. Her eyes glowed nowhere near as intense as yours did hours ago. The glowing eyeballs raked him over, as distaste settled over her features.
"Goodnight, I'm sorry to bother you so late but is-"
"My child does not cry easily."
"Uh, excuse me?"
"My child, was the top warrior in her school. She is ranked across the planet for her skills, she could've become the next leader of our entire planet. She is smart. She is kind, she makes good choices. Most of all she is strong. We left our home planet, she had to start the journey to living amongst humans against her will. Not once did she break. She does not cry easily."
Silence as her eyes began to glow a more intense color.
"You made my child cry." Then the door shut. But for a moment, he saw you. Laying on the couch, your father patted your hooded head. Covered in Mark's hoodie that he gifted you and you hugged yourself close.
He stood there on your porch; through the door he heard your parents comforting you in your own language and he recognized the few words you taught him.
'Mama, what do I do?'
Fuck, what did he even do?
He never realized how much he would miss your honesty. Mark knew it was something he loved about you, but sometimes it could be a bit difficult. You were always in his head. You just always knew and after months of dating, he was still a bit freaked out. You knew him better than he knew himself.
After a year-
The porch was dark, Mark had been in the dark all day about what had you so enraged with him. But finally the light turned on in his brain and he never felt so stupid. A wind blew over him, like the truth that revealed itself to him.
Today had been a year since you two had gotten together. Lifting off, he made his way to his own roof and planted his bottom firmly on the spot he so often sat on. And he thought back over the year.
You helped him sort himself out for a year. You planned your six month anniversary. You planned his birthday party. You reminded him when Valentine's Day was approaching. You helped him plan a birthday party for his mother. You made him dinner the best you could when you got the hang of Earth cooking. You saved him from countless battles, you encouraged him to keep his head up. Even after a devastating loss, you encouraged him to keep his head up. He couldn't remember one day.
You even told him it would be nice if he planned something for once. And he couldn't remember one day.
༻༺༻༺༻༺༻༺༻༺༻༺
His mom tore him a new one, but it was nothing compared to you. You became more like an Earth girl with each passing day, evident by how you'd been giving him the cold shoulder for four days now. Even gossip articles picked up on it.
'Invincible and SuperNova split?'
'SuperNova snubs Invincible after battle!'
Instagram was clowning him. Evident by the comments William was reading out loud to him as they sat in the car with Amber and Eve during lunch. Also, the meme going around of him edited as Art the Clown. They dubbed him 'Invinciclown"
"Oh man this ones funny, 'bro fumbled a baddie', 'SUPERNOVA ONE CHANCE PLEASE!!!', 'Omniman knocked the game out bro', 'The fumble needs to be studied'. Lesbians have also never been happier since you're out of the picture."
"Honestly the entire LGBT community has been praying for your breakup." Amber chimed from the back, scrolling through edits on her phone.
"Look at this."
"NO WAY SOMEONE MADE A BREAKUP EDIT!" Eve yelled, hands dramatically on her head. The internet decided it was over already.
"We aren't broken up. I'm not out of any picture." Mark sulked, head pressed against the glass.
"What's it like being emo and delusional?" Eve snickered, leaning back.
"That's not hot Mark." William added, making dramatic gestures with his hands.
"You're not Paris Hilton. And we aren't broken up. She's mad at me."
"Okay but why is she mad at you? She's been ducking you for almost a week now. She doesn't even duck fades and she's avoiding you." Always sympathetic Eve brought reason back to the car.
"...I forgot our one year anniversary."
....
"The fumble really does need to be studied."
"One year...yeah man she needs to break up with you, that's ghetto as hell."
"I tried saying sorry, but she doesn't want to talk to me! She fought a Kaiju and Doc Seismic on her own before she chose to speak to me. She almost got eaten and literally chose to handle that before talking to me."
"Well, she's tired of spelling everything out for you. What have you actually planned for her that's important? Answer quickly." Amber responded. When was her foot not on Mark's neck?
He couldn't even answer slowly because you typically spell everything out for him.
"Okay but what do I do?"
"Give up?" Eve suggested.
"Accept defeat?" William offered.
"Die because of how bad you dropped the bag?" Amber added her advice.
"Guys I love this girl; can we be serious?" The words came from the depths of his heart. Then silence filled the car again.
"YOU'RE IN LOVE WITH HER?"
He was in love with you. He was in love with you and was sitting in a car with his friends while you, the woman he loves, was somewhere. You weren't with him at lunch because he pissed you off so bad you didn't even want to try and communicate.
"I gotta go."
༻༺༻༺༻༺༻༺༻༺༻༺
"Why are you in my bedroom?" You asked, rolling over in your bed and eyeing the man sitting on your bed.
"You haven't been talking to me." Mark figured out pretty quickly where you were when you didn't return back to school. He spent the rest of lunch looking all over the city for you, saw you didn't show up to your trigonometry class and figured you just blew off the rest of the school day. So, he did the only thing his crazy and stupid heart could think of. Because Mark is crazy over you. Even though it took disgustingly long for him to lock in and act like it.
You pulled your covers back up to your chest and rolled back onto your side.
"I do not need to talk to you. You are my ex boyfriend. I do not need to be friends with my ex boyfriend." Did you just stab him and twist the knife? But he had to push on. Because this was not about him. This wasn't about making him feel better, it was time Mark showed you how much he cared.
It was time to be brave, but this was scarier than any battle he'd ever been in.
"...I'm sorry I forgot our anniversary."
"I am sorry that you think that means anything to me four days later."
Okay you were not having it with him.
"You don't want to be with me anymore?"
You tossed the blanket over and sat up. You looked at him and the back of his brain wondered how long you'd been home. You were in a fitted tank top, pajama pants, makeup gone, contacts removed, and your hair gently placed under your bonnet.
"I want to be with someone who cares for me. You do not want to be with me. You have shown me that you do not care for me the way I care for you. I have my struggles. I have my burdens. I have carried your burdens and mine for the past year. I do not put these on you. I ask that you take care of me the way I attempt to take care of you. I asked one thing of you Mark Grayson. You did not do the one thing I asked of you, Mark Grayson." Then you flopped back down on the sheets as if holding eye contact with him was killing you. He cracked, eyes watering and voice cracking.
"I'm sorry. I am sorry baby, I am. I know you needed someone, and I am that someone for you. I didn't mean to let you down. I was so used to you knowing everything already that I forgot that everyone needs someone. And I need you, I can't live without you." He drew closer to you. Mark was absolutely begging. Because you taught him better than to hide his feelings and hiding them right now would only make things worse.
"Things shouldn't come to this extreme for me to realize that and I'm sorry. I...I love you." And with that you shot straight up in the bed. You were staring at him with curious eyes.
"You...love me?"
Mark swallowed thickly, and he blinked away tears. He took his hands in yours, ignoring the way you raised your eyebrow. You didn't yank your hands away, a good sign?
"I love you. I love you. Not just what you do for me, not just how you look. I love you." He breathed. Your eyes filled with tears, and Mark brung his forehead to yours. His heartbeat slowed; the world stopped spinning for a moment. Your heartbeat matched his.
"It is against my customs to forgive you. On my planet, I would be expected to leave you and never look back. You have made a grave error, you have failed to value you me the way I should’ve been all along.”
He swallowed thickly, eyes trained on his hands holding yours.
"But I am not on my planet. And you are sorry. I see your heart, you intend to improve. And I love you. So, against everything I know, I forgive you Mark." It came out in a whisper.
"You forgive me?" His voice was hoarse, from the crying and disbelief.
"I forgive you." Eyes finally met and he saw tears running down your cheeks.
"You love me?" Your lips drew closer to his and he found his knees weakening.
"I love you."
