A/N Hey guys, I recently read a few fanfictions with an Avenger/Hermione crossover and really loved it. However, there isn't many to read, so I decided to make my own. Hermione's character will be a little different, I'm planning on making her much more badass. Also Civil War didn't happen and Peggy existed but she was just a friend of Steve's not a romantic interest. Enjoy!

Chapter 1:

The Avengers were all lounging around the top floor of STARK tower, Tony was of course drinking and fiddling around with his Iron Man suit, Steve was cleaning his Captain America shield while catching up on some music he missed when he became a popsicle for 70 odd years, Tony had suggested Black Sabbath so that's who he was listening to. Clint was up high, feet dangling over the edge of a large metal beam. Tony had the beams installed for Hawkeye after realising that being up kept him sane when they had no battle to fight. Bruce and Natasha were sitting crossed legged on the floor facing each other in a chess match. Bucky was sitting next to Steve reading 'American Assassin' by Vince Flynn, 'It's a good book this is.' He thought. Wanda and Thor were in a discussion about the different types of magic of the Realms, Peter Parker was up with Hawkeye napping in the little web bed he'd made for himself and Vision was watching amused as Scott (Ant-Man) was questioning Logan about everything to do with mutants and his claws, the battles he's been in and how long he's been alive for, as Logan drank and smoked his cigars. It really was an ordinary day, soon enough Nick Fury would come around and brief them on the coming week, concerns he had and would assign missions. However, for now, they were all just relaxing in peace.

"Hey guys, whose messing with my tech?" Tony questioned, his voice annoyed, the rest of the Avengers looked up to see the screens surrounding Tony glitching out.
Wanda jumped up from her seat next to Thor with a yelp, "I can feel magic, strong it's different, it's not like mine or Loki's, it's to strong" she said with an almost pained voice. "It's so overwhelming."
"Guys, what the fuck is that?" Natasha spoke, a small bright light started to appear in the centre of the room, growing larger and stronger at each passing moment, The Avengers as one leapt to their feet as a scream ripped through,
"I can't scan it, JARVIS isn't responding!" Tony sounded panicked.
The light flashed and disappeared as suddenly as it appeared. The Avengers started shouting over each other trying to figure out what happened. Only Bucky stayed quiet, his eyes fixed to the small body of a woman, curled up on the ground, he swore as he saw her bloodied body and matted hair.
"OI, SHUT THE FUCK UP, THERE'S A WOMAN HURT" he shouted, all noise immediately ceased, Bucky crossed the room in a matter of strides, kneeling down next to the woman brushing away her hair, her face was small and pixie like, a large cut curved from the tip of her left eye brow down her face to her chin, narrowly missing her eye, it was fresh blood pouring down her face.

He recognised her immediately, 'Shit, shit, shit, shit, no, don't do this to me love!' Bucky quickly inspected the rest of her body, he saw a stab wound in her side, and her right thigh, pulling of his shirt and tearing it in half he turned to the other, all just standing around like idiots.
"She's hurts, she need's medical attention, I'm taking her to my room…" he was cut off by Peter, "Wouldn't a hospital be better?", "No!" both Wanda and Bucky yelled, "She looks like she's been tortured, the last thing she need's is to be in a public hospital with the police and doctors asking questions" Bucky stated firmly. The Avengers looked at him oddly, Bucky's voice was full of pain and worry, it was almost as if he knew her.
"That's not all," Wanda spoke softly, all heads turned to look at her besides Bucky, who was busy wrapping the makeshift bandages around her thigh and side, "She's a magical being, it runs through her blood, the doctors would want to run tests and once they picked up on her abnormality and her accelerated healing she would be taken away to a lab. We can't let that happen."

"Right, everyone listen up," everyone turned to face Tony, "Bucky get her to your room, Wanda, Banner, Vision you go with her, Wanda you're going to monitor her magic, let us know anything you can, Banner set about fixing her up, Bucky hold onto her, we know nothing about her and if she wakes I get the feeling you're the only whose going to be able to calm her down. Vision you're going with them as back up." The 4 left the room, the small woman wrapped firmly in Bucky's arms. "Scott, Logan, you should head off and let Professor X know what's happened, see if he can help figure anything out, we might need him to talk to her, Nat, Clint, go tell Fury and ONLY Fury, don't let word of this get out." Another nod and both groups were gone.
"Thor, Steve you guys stay here in case anything else comes through, Spidey makes up some food, you're the best cook here and the girl might need some food when she wakes up."
"On it boss," Spidey jumped down and started cooking up a feast.

"JARVIS?",

"Yes sir" a voice echoed throughout the room, "I want you scanning everything that just happened, and scan the girl to, I want to know everything possible about what just happened"
"Of course, sir" came the reply.
"And JARVIS, bring up her room, I want to see everything that's happening"

"Sir, you might want to see this, it seems the girl is waking up" JARVIS spoke, it had been about 3 hours since the young girl had appeared, Fury along with Nat and Clint had returned, he'd asked to see the girl. The scene that followed was extremely confronting and terrifying. He had taken one look at the girl and ordered everyone out of her room as soon as she was stable. Bucky
however didn't move, he sat by her side holding her hand, tears threatening to spill over his cheeks. Fury sighed, "How much do you know about her?"
"Everything" Fury watched on as Bucky lifted his shirt and turned around, across his back, between his shoulder blades was a tattoo, it had 3 circles within each other. Fury sighed again. "I'm sorry, but you need to come and sit with the others, they need to know."
Bucky nodded, pulling his shirt back down, he leant over and kissed his soulmate softly on the forehead.

Once everyone was in the lounge again, Fury started to speak. "Her name is Hermione Granger,"
"No! Fucking hell!" Steve spoke softly but everyone heard, they knew immediately that whatever they were about to be told was going to be hard to hear, after all, Steve never swore.
"She is a witch. What I am about to tell you is to remain in this room, no one else is to know." And so, he told them, he told the story of Hermione, Harry and Ron, of the wizarding world and the pain and torture the young woman had gone through. Nick was aware of the magical community, he was a wizard himself, and his brother Kingsley Shaklebolt knew the young witch personally. As he wove the tale of Hermione Granger, eyes widened, jaws dropped and tears were shed. No one could believe or understand how a human could seek out to destroy another like that. As to why she'd appeared here, it turned out Hermione had been enlisted for a special task force, elite Aurors (magical terrorist hunters, was the best way to describe it) Hermione was one of their best but she'd been caught and had been missing for 2 days, Nick explained that the physical and emotional pressure she'd endured caused her magic to become unstable and in order to defend and protect herself she'd let loose a wave of magic that transported her to the one person she felt safest with. It was incredible dangerous and only worked if the witch/wizard using the spell had found their mate.

Upon finishing his tale Bucky quickly left the room and returned to Hermione's side. The Avenger were once again left confused, all of them could feel the anger radiating off Bucky.

Tony looked to Fury and asked, "What aren't you telling us? How did she end up here if that spell was supposed to take her to her soul mate? Also what the fuck is up with Bucky? I've never seen anyone so torn up before? What haven't you told us Fury!?" Tony's voice was deathly calm.

Before Fury could reply a voice cut in; "The spell worked fine, it did take me to my soul mate, soul mates share a bond, this bond allows each person to communicate in ways different to other couples. Bucky was torn up because he could feel my pain, he could sense my distress, yet he couldn't do anything to help ease the pain I was going through. He's my soulmate."

Everyone's head had turned to the woman speaking. Her voice was soft and calm. Her hair was inky black and matted with blood, the cut on her face had healed and now looked to be month old instead of mere hours, her eyes were a bright amber. She was dressed in slim black jeans and what looked to be a type of leather boots, that came half way up her calf's. She was slim, and short, about 5'6, tiny next to Bucky's 6'2 figure. Bucky's arms were wrapped around her waist, her back pressed against his chest, his head was nestled in the crook of her neck, gently placing tiny kisses along the shoulder, trying to convince himself she was really there.
"Mya?" the young witches eyes darted to his face and she smiled softly, tears still evident on her face,
"Hello Steve" before she could continue she was wrapped in another pair of arms, Steve's head nestled into the crook of her other shoulder, he started to cry, not loud sloppy tears, soft tears, tears of disbelief.

The Avengers looked on in confusion, the small woman who only hours ago had appeared on the floor of Stark Tower, unconscious and wounded was now wrapped in the embrace of two of the strongest men in their team, comforting them as they cried. There arms tightly grasping her as if they hadn't seen her in years.

"Ms Granger, I think it may be a good idea to let everyone know how yourself, Bucky and Steve know each other. As for the rest of you, sit down, shut up and don't interrupt. This is going to be difficult for all three of them, stay patient, and good luck." With that Fury left.

Steve detangled himself from Hermione and dropped a kiss to her forehead. "Steve, there's something you need to know, it's about Luna. She's alive, she's young, she's like me." The Avengers were once again confused as Steve fell to his knees, tears once again leaving his eyes. "C-C-Can I see her, please?"
Bucky unwrapped his arms from around his loves waist, Hermione dropped to her knees beside Steve and pulled him once again into her arms. "Of course, I'm going to go get her okay, right now okay."
"Not without me, don't even think about it" Hermione looked up to Bucky as he spoke. Raising herself to her feet, she placed her hands on his face, forehead to forehead they looked at each other. "Trust me, my love. I'll be back before you know it." Dropping a kiss on his nose she stepped back, spun and disappeared with a crack.

Bucky helped Steve to his feet, clapping each other on the shoulder they turned to look at their team mates.

"All right everyone, sit down, she'll be back soon, then we can talk." Bucky's voice left no room to argue and everyone sat down.

"I can't believe they're both alive!" Steve whispered,
