Bakugou remembered the first time he'd seen Mercy. The crimson eyed 8 year old had been minding his own business when two older boys had shoved him. Admittedly they may have been the older brothers of the boys he'd bullied the day before but still they were teenagers. Much bigger and had better use of their Quirks. Granted Bakugou was mastering his at an alarming rate, he was still no match for them by his self. He'd just been pushed to the ground when someone smaller than him had stepped in the way blocking the ash blond from their view. Spreading her arms out wide, wider than the toughs of cerulean downy feathered wings could reach she planted her feet. "L-Leave him a-alone." Naturally they'd laughed at her.

"Oh, and what're you gonna do, you stupid blue chicken?" A whip like tail tipped with a small heart shaped arrow head swept the ground behind her inches from his shoes. Reaching forward the bigger teen plucked a feather making the trembling girl wince.

"I-I'm warning you." A slight lisp had them laughing as they shoved her down. Crying out as she'd landed on her tail her electric blue orbs darted his way. "Please. Jush leave us alone." The fatter one snorted.

"Yeah right. Time to learn your place girly." Shutting her eyes tight the golden haired girl bit her lip hard enough a little fang drew blood. "Oh, are you gonna cry now, big baby?" The boys flinched. Nervously glancing around. A cold sweat broke out and they were stepping backwards nearly stumbling over each other. "Hey what gives? What is this?" A glowing orb cracked open bathing her pale cheeks in a neon blue.

"If you leave us alone I'll make it stop. Jush walk away." They yelped tripping over their shoes on the way around the corner. Feeling her hold over their emotions snap as they exited her range the little blonde sighed leaning back on her hands. Chancing a glance over at him she'd beamed baring her teeth, which included a decent set of fangs. That was the first time his heart had skipped a beat over a girl. "You okay, dude? They didn't hurt ya or anything?" He scowled remembering his self. He was Bakugou Katsuki, he didn't need any help from anyone. Especially a girl. He snorted pushing to his feet. Dusting his shorts off the ash blond narrowed his crimson eyes. The tip of sapphire horns were just starting to peak through the bangs to the side of her head. He wondered for a moment if she was part animal or something.

"I didn't need your help. I would've been fine on my own." She shrugged. She could feel his embarrassment; he didn't need to say it. Pulling her beanie back over her head where it had fallen off the girl waved as she continued on her way down the street.

"Sorry then." Crossing the street, she'd ducked into a grocery store and out of his sight. He thought nothing of it until the next Monday when she was introduced as a new classmate. She'd seen his familiar spiky hair and made a dash for the seat next to his. The crimson eyed boy had barely kept from banging his head off the desk. As if Deku wasn't bad enough.

Twirling her pencil at the tips of her fingers Mercy yawned listening to the teacher drown on and on about high school entrance exams. She already knew where she was going, so there was no point. She was passing with solid B's and aside from her more notable fights with Bakugou her record was clean. Said boy was kicked back in his chair, feet propped up on his desk. A sudden snort made her aware she'd missed something. "Of course the Quirkless loser wants to go to Yuuei. But ya know what? I doubt they'd let someone so worth-" Shaking her head the empath wrapped her tail back around her waist from using it to unbalance the explosive Quirk user enough to send him tumbling backwards. Rubbing the back of his head, he'd banged it pretty hard on the way down the ash blond jumped up. "What the fuck, bitch! I wasn't even talking about you! You wanna die?!" Rolling her eyes the blue eyed female sent Bakugou a disinterested look. The quickest way under his skin was to act like you weren't paying any attention to him. It drove him crazy.

"I'm sorry, Kit Kat, did you say something?" Snarling he let his Quirk activate. Tiny sparks crackled to life in his hands. The teacher finally noticed.

"Bakugou! No Quirks at school!" Flinching the crimson eyed male retook his seat grumbling. Waiting for the teacher to turn away Izuku leaned sideways in his seat.

"Thanks, Mercy. You're a life saver." She waved him off sticking her hands inside her uniform jacket pockets.

"What're best friends for, Izu-kun?" Her phone buzzed inside her pocket. From the look of death that Katsuki was giving her it was from him. Pulling her smartphone free she scanned the message.

He needs to learn the truth eventually, Heifer. That fucking hurt, ass wipe. She scowled whooping him on the leg with her tail before sending him a reply.

As hard as your head is, you'll be fine. There's nothing wrong with Izu-kun having a dream to chase. Ease off, Kit Kat. She saw him bare his teeth at his phone as he read her message.

Bite me, bitch. Deku's a Quirkless loser and he always will be. He's hardly worth anyone's time, least of all ours. She frowned at the strange wording. Maybe it was an auto correct of 'mine' in his phone. Mitsuki did enjoy changing them around to mess with her son. Mercy would have to stop over again soon, she hadn't visited the older ash blond for a while. Bakugou's parents were nice people. To her anyway, she could hear Mitsuki screaming at Kit Kat from her house two blocks away. Practically vibrating in her seat the golden blond female was up and nearly gone when she realized that Izuku was still gathering his stuff after the bell had rang. Making her way back over she accidently bumped shoulders with Bakugou as he snatched the greenette's hero notebook up.

"You'll never learn will you, Deku? We ain't done yet." One of the ash blonde's followers leaned around him to read the front of the note book.

"For my future? Seriously, Midoriya?" Katsuki grinned, slamming the book between his hands, an explosion scorched it. Mercy gasped yanking the book out of his grip. Patting it off she bared her fangs at the smaller boy.

"You asshole, there was no reason for that at all." He shrugged.

"What's he gonna do? Not like he has any power. Me and you are gonna be the only ones to get into UA from this crappy public middle school." She narrowed her icy blue eyes. At times like this she wished she could just punch the shorter blond in the face. It was too close to high school though. Only ten more months and hopefully she would at least be in a different class than the temperamental boy. Ever year so far they had always ended up right next to each other, and paired together no less. Feeling her feathers ruffle under her jacket she huffed.

"He may not have any power or a Quirk but I do, and that was completely uncalled for you jerk." He shrugged again, stomping towards the door. Katsuki wasn't normally that calm but she had a pretty good read on his emotions and he was feeling good today a little hurt but good anyway.

"Maybe he'll get a better Quirk in the next life if he swan dives off the roof." Izuku jolted, rounding on the other boy. The crimson eyed teen let his Quirk activate, explosions echoing in the room around them. "You got a problem, nerd?" The emerald hued boy crumpled in on his self. "That's what I thought." Mercy was shaking with rage, Katsuki thought it wise to make a quick exit. Waiting until he was out of her range she sighed looking down at Izuku.

"Don't lishen to him, Izu-kun. We'll both be heroes one day. I'm supposed to be your sidekick remember. Kit Kat won't know what hit him when he gets stuck as the number 3 hero." He sniffled, wiping his eyes.

"Yeah, you're right. Kacchan doesn't know what he's saying." Walking with Izuku at the front of the school Mercy ticked off inside her head what all she needed for dinner tonight. "I'll see you tomorrow, Mercy." Waving she beamed.

"Yeah, if you have any queshions text me, okay?" Starting towards the market she shrugged her jacket off and let her wings unfold a bit. It didn't hurt to keep them folded up all day but it was uncomfortable. She couldn't leave them out during class, then Izuku couldn't see behind her. Thanking the lady behind the register at the store Mercy cut through an alley to shorten her way home. She squinted. Yeah that was Bakugou and his followers. Minions more like.

"Come on, Bakugou. We can sneak into the club down town and try to pick up girls." The ash blond crushed a can in his hand, exploding it. Mercy snickered stepping out from behind the dumpster she'd passed.

"You idiots, if we get caught there's no way UA will let me in." Letting her tail loop through the bags she was carrying the winged female snorted planting her hands on her hips.

"You say that like you actually have a chance at picking a chick up." Bakugou rounded on her.

"Of course I have a chance, dip shit. You're the only Heifer in our class that's completely fucking brain dead. The other girls would kill to date me." She shrugged letting a grin lift her lips.

"I think I'll take my chances on being brain dead. Seems smarter. You have fun dating every girl in class though." He blinked. Brows dropping down, narrowing his eyes.

"I didn't mean it that fucking way. I'm gonna be the number one hero, so the girl I do pick has to be worthy of me." Mercy rolled her eyes cocking her hip out. She was one of the fuller body types in class, a near perfect pear. Holding her hand up she wiggled her fingers.

"Whom so ever holds this hand, if they be worthy, shall posses the power of- Ow, Kit Kat!" He'd smacked the back of her head nearly dislodging her hearing aids. Muttering to herself she pulled her beanie down further while pushing the devices back in all the way. There was no telling what Kit Kat would say if he ever found out she was mostly deaf. It was why she had a lisp and why she stuck so close to Izuku on her bad days. She'd taught him to Sign when he'd asked. Katsuki had just thought she was ignoring him, not that she couldn't hear him very well without help. She was just now getting good at reading lips. She was a slow learner in some things. Shoving his hands in his pockets the shorter blond scowled.

"Some times you're worse than, Deku. Why do I put up with you, again?" She shrugged honestly having no idea.

"Cause you love me, duh." She missed the way his eyes widened and he started to sputter. "I'm joking. It's cause I'm an annoying cow. That's a direct quote by the way. That and no one else will put up with your ass after school hours besides your followers and your parents." He pouted, giving her a glare that made lesser teens run for their lives. A sudden shiver ran down her spine. Glancing up she nearly screamed seeing a blob monster towering over Katsuki's shoulders. "Look out!" Tail unfurling the winged teen sprinted forward shoving Bakugou out of the way. The villain slammed into her throwing her into a wall head first. Katsuki landed hard on his back, jerking up he opened his mouth to scream at her for doing something so stupid but froze seeing the green mass holding her by her neck. His followers had turned tail to run as soon as they'd seen what had happened. Mercy could feel the blood sliding down the back of her neck. Her vision swam and she was clawing for consciousness. Trying to shake her head she winced. She definitely had a concussion. With her mind foggy and unclear she couldn't used her Quirk. Gripping the slug covering her mouth she realized she couldn't breath.

"Let her go you bastard!" The thing grinned.

"Oh I'll let her go, but only if you agree to go in her place." Mercy panicked. No! Bakugou wouldn't do that, he couldn't do that. Vision dimming more the female gasped when the hand over her mouth disappeared. Sliding down the alley wall she watched helplessly as Bakugou was over powered and covered in slime. Panicked crimson orbs locked with her own before the world faded to black.

Groaning Mercy clutched her head, whatever had happened it hurt like a bitch. The bright lights of the ambulances were nearly blinding. No someone was shining a light in her eyes. The paramedic nodded before turning to look at someone else towering over his shoulder. Looking into a pair of familiar electric blue eyes she tried to smile, it didn't work. "She has a mild concussion. She'll need to go to the hospital. The neck brace will also have to stay on until the doctor clears it. Head wounds with mental Quirks are a tricky thing." Moving her eyes around she spotted broccoli hair. When had Izu-kun gotten here? And why were the pro-heroes lecturing him? Kit Kat was a few feet away and he was being praised. Every few seconds the crimson eyed teen would look her way. Catching his eye she cracked a small smile. He turned away and didn't check on her again. It was her fault she was like that anyway. If she hadn't pushed him out of the way she would still be fine. She hadn't saved him by taking the hit for him. He didn't need saving. If anything he'd saved her by taking her spot. They loaded her into the ambulance after that and she waited until the MRI's and other tests came back before being able to see her dad.

She'd taken after her dad with the height and coloration. People even said they smiled alike. Baring all their teeth. Mercy hadn't even known what her dad looked like until she was nearly 9 years old. Her parents were Pro-Heroes. Some of the worlds best if truth be told. Her mother was caring and compassionate while her father had raw power on his side. She'd gotten her mother's Quirk or a variation of it. Her mother had had the wings and horns and the ability to sense emotions. Mercy had added a tail and the power to control what people were feeling as well. Mercy had learned at the young age of 6 that she had been the result of a one night stand between the Pro-Hero Golden Angel who was as caring as she was beautiful, with shimmering golden wings and brilliant cerulean eyes and the Pro-Hero All Might, the symbol of peace before he had become the symbol of peace. He hadn't known he'd fathered a kid until Angela, her mother had fallen in battle. It had been in a letter her sister was to open only if it were to happen. When he'd marched into the room the first time she'd saw him there was no denying that she was his. Even with her mother's animal Quirks he shined through. She'd watched him slowly waste away before her eyes. The surgeries and so called treatments nearly worse than the actual wound he was suffering from. The skinny form of her father was hunched over in a chair when she was finally wheeled to a room for the night. With one of her Quirks relying on her mental abilities they had made the choice to keep her over night for observation. If she had a night terror and wasn't in a capable state of mind everyone on the street would be missing out on sleep for a few days. Toshinori was up and moving before the nurses had even pulled her to a stop. Taking her hand in one of his the taller man sighed in relief.

"I'm so glad you're okay. You have to stop scaring me like that, Mercy." She went to rub her head stopping only because she remembered it was bandaged.

"Sorry, Dad. I don't know what happened. One minute I was teasing Kit Kat and the next I was pushing him out of the way. My body jush moved." Toshinori slumped. Of course she had just moved, she did want to be a hero. And she'd make a good one too once she was trained. Easily in the top 10 if she every got the hang of her empathy. "I losh the groceries." He smirked, shaking his head.

"Of all the things to worry about at a time like this. I'll get more groceries when they kick me out of here." She nodded still a little woozy from her head trauma.

"I was gonna make your favorite." He beamed settling back in the chair he'd just jumped out of.

"You're by far the best daughter I have." Mercy cocked a golden eyebrow.

"Unless you were a man whore when you were younger I should be the only daughter you have. In which case you're a little bias." His sunken in eyes widened.

"Mercy!" She laughed nearly jumping out of her skin when her phone buzzed beside her on the bed. They'd made her put on the normal paper hospital gown and it was driving her nuts. She hadn't been able to answer her phone since she'd been wheeled in and she had missed calls and messages from Izuku and texts, as in multiple, from Katsuki. Hell even Mitsuki had tried to text her. That clued her in on something being wrong, if Kit Kat tried to text you more than once without a reply from your end that meant he was worried and probably throwing a tantrum at home. The ash blond didn't handle emotions well, especially ones he wasn't used too. Mainly worry or guilt. Sending the greenette a quick message letting him know she was fine she scanned Bakugou's texts.

I already got internship offers. Suck it! That was sent 20 minutes after the villain had been captured.

And All Might shook my hand. Deku's gonna hear that in the morning. He'd at least waited 15 minutes to try again.

You really missed a lot fainting like a weakling, Heifer. 10 that time.

The nerd even tried to save me. It back fired and he ended up being saved, Quirkless Loser. Now he was trying to bait her into replying.

I get it. It's not funny anymore.

Oi, answer your damned phone, bitch.

Where the fuck are you? No ones at your house. I've got your damned food.

If you ended up dead, I'll kill you my fucking self! This isn't funny anymore you stupid cow! It was nice to know that he cared so much. Pecking out a response she shook her head.

I'm fine Kit Kat. Had to get tests done and couldn't have my phone. I have to stay over night to make sure the bump to my head didn't mess with my Quirk. I should be at school some time tomorrow if my dad doesn't make me stay home. Could you put the food in your fridge, pretty please with extra chili powder and hot sauce? Her phone buzzed back almost instantly.

Such a pain. All that for a dumb 'bump on the head'? You probably look shittier then usual then. You'll need all the beauty rest you can get. She scowled at her phone. Fingers speeding over the keys she typed out her reply.

It's a mild concussion, Kit Kat. I'm sorry my head isn't as hard as yours. Bite me. She backed out of that message to check the one from Katsuki's mom.

Hey, kiddo! Every thing okay? The brat's being pissier than usual. Since you're basically his only friend I figured you'd be the one to ask. She responded with yes everything was fine and she'd explain tomorrow since she still had her dinner plate she'd made Mercy take with her because it was covered in cookies. It was like Mitsuki thought she had to bribe people to come back to her house because of how fowl tempered her son was. Grated Mercy was sure that the only people Bakugou had ever had over were Izuku and herself. And Izuku had stopped going before she'd even moved here. She turned the volume on her phone down because she was really sleepy and it would probably be going off all night with news updates.

It became apparent to Mercy after 2 weeks that Izuku was avoiding her. Unintentional as it may be. It still hurt. She understood he was probably a little traumatized after the sludge villain attack, but still she was his best friend. She would always be here for him. Leaning against the arch to their school she sighed realizing he was already gone today too. A snort to her left drew her attention. Icy blue locked with molten crimson. "What? The loser ditch you too?" She rolled her eyes hefting her bag higher on to her shoulder.

"He's probably busy cramming for the UA entrance exams. He only has 10 months and unlike us he actually has to try." Pushing off the arch she set a steady pace for her walk home. Technically she lived a few blocks away from Katsuki. Shoving his hands in his pockets the ash blond trudged along beside her. She clasped her hand behind her back letting her tail wave lazily without much thought.

"Like Deku actually has a shot." She sighed.

"Excuse the rest of us for not being born with a powerful Quirk. I'm going to have a hard time too. Last time I checked robots don't have emotions. I'll be lucky if I make class 1-B." She cut her eyes fast enough to see him scowl. "Izu-kun has always looked up to up, ya know? For some reason he seems to think you're a good person." He growled letting off a few small explosions next to her feathers. She shifted away. It took forever for them to grow back when they got burnt off, she'd learned from experience.

"Hey, fuck you, Heifer! I'm gonna be the number 1 hero someday." She gave a small smile.

"Setting your sights a little high ain't ya?" She danced out of the way when something sparked next to her head. She laughed watching his eyes narrow.

"Fuck off, bitch." After 5 years of the verbal abuse she'd learned to take it with a grain of salt. Katsuki was raised to be brash and loud, Mitsuki could often be heard yelling from 2 blocks over. Blinking she glanced around.

"Say, Kit Kat? Where're your followers at?" He ground his teeth together. He'd forgotten how annoying the cow could be, she had been given two days to recover from the villain attack and he had cherished the silence. So what if he was snappier and angrier. It wasn't because of her dumbass.

"None of your damn business." She cocked a golden eyebrow.

"You know, you're the one that choose to walk home with me. Feel free to go a different way anytime, asshole." The crimson eyed male stopped then stomped off in the direction of the park. It was the closest he was gonna get to nature without going hiking. Mercy shrugged, ruffling her feather underneath her school jacket. Only her longer flight feathers stuck out from underneath it but Bakugou would burn them all the same if she didn't pay attention.

The next day after school Mercy headed to the roof. If she couldn't catch Izuku on the ground she could in the air. As much as Katsuki though her feathers were just for show, she could fly. Shrugging her jacket off she stuffed it into her bag. Spreading her wings out to test the air she hissed as one of the joints pulled. Katsuki had broken it in one of their fights. He'd kicked out without paying attention and the joint had popped. Making sure her school bag wouldn't get in the way she gave a test flap. She lifted gently. She'd learned the hard way that if she weighted to much her wings just wouldn't support her. Inhaling deeply she stepped off the edge. The blond dropped a few feet before her feathers caught enough air, then she was gliding over the other students. Just incase she did feel like flying home she always wore shorts underneath her skirt. That and with Bakugou you had to be ready to brawl at a moments notice. Flapping to gain altitude the icy eyed teen scanned the area. There! A little flash of green hair moving fast through the crowd. Banking she angled after him.

A shadow passed over Bakugo making him look up. Cerulean wings catching the breeze Mercy rose above the trees and out of sight. He blinked. When had her wings gotten that big. She had to have a 16 foot wingspan by now. The light rays refracted just right making the soft feathers glimmer in the sun. Had they always been that shade of blue, just a bit deeper than her eyes? Shaking his head Bakugo muttered a curse and stomped off towards home. The cow wasn't anything but a pain in his ass lately.

Izuku was moving fast for being on the ground but in the air Mercy was riding air currents and gliding. This was so much easier than walking, why didn't she fly more often? Right, because Izu-kun couldn't fly. Seeing the ocean come into view she tucked her wings in slightly, an ocean gust could send her flying (pun intended) or rip a delicate wing out of socket. Drifting closer to the ground she ignored all the strange looks she was getting. Wings were one of the more uncommon Quirks to have of the physical kind. Only a hand full in the school had them and only 2 could actually fly with them. Landing on the tree line she paused watching the little greenette run up to the larger than life hero All Might. Well that would explain where he went every day. Izuku dropped into push ups and Mercy froze. Surely he wasn't-he didn't- Shaking her head clear the blond smiled. She'd go get some snacks, of the healthy kind, it looked like Midoriya was training to get in shape. Slurping a slushie the icy eyed female tossed up a wave seeing All Might glance in her direction. He froze looking around to make sure no one else had saw them. Shuffling over she glanced around.

"So this is where you've been running off to. Nice to know you'd rather be surrounded by trash than me." Izuku lost his focus face planting in the sand. Jumping up he spat out a mouthful.

"Mercy! What're you doing here? You can't stay someone will see you." She slurped her slushie slowly.

"So people are going to see me before they see the 7 foot tall Pro Hero standing right next to you? The number 1 Pro Hero might I add." All Might cleared his throat.

"Ah, young Miss. Please, we're right in the middle of training." She raised an eyebrow cocking her hip out. If their was one thing to say it was that she had taken after her mother in some way, even her plump figure.

"Okay, and I'll stay out of the way. Izuku is my best friend and I will be behind him every step of the way. Figurative and literally. If you're trying to help him train that's well and good but I know him better. He'll push himself until he breaks and if he's gonna get into UA I can't let that happen. So one way or another I'm staying." Letting her tail snake around her front it wrapped around her drink so she could dig around in the bag hanging from her arm. Pulling a protein bar free she offered it to the Hero. Taking the bar he sighed.

"Alright, if you must." She nodded moving to lean against a near by fridge. Izuku sniffled wiping his nose.

"Thanks Mercy-chan. You're the best." She beamed baring her teeth.

"I know, now come one slacker, get to it already." He grinned before dropping back to the sand. All Might coughed once before puffing back to his skinnier version. Mercy choked. It was still odd to see him shrink right in front of her.

"What the hell?!"

I know, I know. I'm not dead yet. And yes I am starting another story, hooray!

Disclaimer: I don't own anything. Except my OCS.

This will follow the Manga, just with my character thrown it to the mix. She's gonna get beat up a lot by Katsuki and life.

Reviews are appreciated but grammar is not my strong suit and I'm writing this like all my other stories for fun.

Enjoy!
