Avengers Assemble
Okay, this story is mainly going to focus on Iron Man in the beginning but then it will go into the Avengers more!
I don't own Avengers or any related content.
Thanks Hollie for pretty much co-writing this with me and giving me some of the best ideas that will go into this fic!
This chapter is set during Iron Man 1, just building up a bit more of a back-story and a reason to integrate Minnie into part of the team! I will get into the Avengers soon I promise!
I understand that some of the scientific facts in this might not make sense but let's face it, Iron Man doesn't really make sense either so just go with it!
Thank you for reading and I would love any reviews!
Complicated Possession.
Chapter 2 – The Exceptional Girl

Nearly fourteen years had passed since the death of Anna and Tony thought it was safe to say that he'd moved on. He and Minnie got on well together most of the time, they had the occasional argument but so did every teenager and parent. Their main argument that cropped up every so often was that Tony had not considered that Minnie might want to know more about her mother and he had hidden everything to do with her, the problem was he couldn't remember where he'd put it. Neither could Jarvis which provided a real problem. The only thing he still had was the red ribbon which he planned to give her for her next birthday.

And then he'd been kidnapped. She'd been the first person he'd seen when he came back; she didn't give him much choice. As soon as the plane doors opened and he walked down she came hurtling at him and threw herself into his arms. He had been so scared whilst there, scared that he might never get to see her again. He held her tightly, he didn't care about the ache in his chest caused by his circle of light, he just cared about the fact that his little girl was weeping into his chest because she was so happy to see him.

She'd grown into a pretty young girl; she held a lot of her mother's qualities as well as his own. She had blonde hair with a gentle curl, unlike her mother's angelic, shimmering hair, hers was more golden. She wore it in pigtails and when in these pigtails they fell to her shoulders and bounced against them sweetly. Her eyes were a dark green and they glittered when she smiled. She'd inherited most of her mother's facial features and height, a little taller than the average thirteen years old she gained the impression of being older. She could pass for fourteen, fifteen at a push. Her fourteenth birthday was nearing anyway.

He'd been back two months now and was well into working on the suit, she would stand, leaning against the door and watches him. For the past week she'd gotten closer and closer. He didn't have any secrets from her and so he let her watch and answered any questions she had. Today for instance, he was building some of the equipment and was struggling a little when a small voice came out from nowhere. He hadn't realised she'd been watching but sure enough she leant against the door frame, her blonde pigtails resting on her shoulders, a look of awe on her sweet face.

"Can I help?" she asked and he forced himself not to laugh.

"I don't think you really can." He said without looking up from his work but hissed in pain as he received a small electric shock. She giggled lightly and walked over to him, she took the tools out of his hands and he watched with a raised eyebrow, waiting for her to fail so he could get on with things. But amazingly, she managed it. He was impressed now.

"Okay." He said curtly before handing her another part of the machine which he'd broken earlier, "Fix that." He watched her curious face with an aura of smugness. She wouldn't be able to fix it and then she would look silly. But she managed it. By now he was just annoyed that she could do it and he couldn't. "Fine." He muttered handing her some more tools, "I need you to re-calibrate the thrusters so they use less energy so more energy can be put into the screens, I want it hi-def." Looking pleased with herself she got to work. It was clear that while she had gained her mother's looks she had gained her father's brains.

Her apt for technology seemed to shine brightly as she worked quickly and efficiently. Even Jarvis had little to say to improve her work; both he and Tony were very impressed. "Good work there kiddo!" Tony said giving her a light pat on the back as he admired her handiwork. "With this I shouldn't go flying anywhere I don't want to and I can connect with Jarvis and see things a little more clearly. Thanks!"

She grinned at the praise and also admired her work, "Imagine if you didn't need a suit…" she said wonderingly, "Imagine if you could just do all these things, just do them with yourself. Control them with your mind…" Tony gave her a look.

"That's going a bit too far. You'd have to have brain surgery or something like that." He said shortly before walking away, she remained staring at the suit though, wondering.

Tony was called upstairs and so she set to work right away, unsure how this was going to work but she was certain she could do it. The technology was easy to make and in almost no time at all she had the serum to allow the energy waves to pass through her bloodstream and the tiny micro-chips that held the energy required. It was the same technology her father was using for the suit; she just planned on putting it into herself instead. The next few hours were spent sat in the corner of her father's work place working on the brain serum and micro-chip. Tony was right, if she was going to do this she would need to have the brain surgery to be able to control it. With the correct chemicals she could remain awake and do it herself and keep it as a surprise for her father.

She knew that whatever followed it would be painful. But she had all the same technology that went into the suit; the only difference was she planned on putting it into herself. It would mean she would have the energy bullets, the thrusters and enhanced senses. The only thing that would be missing would be the metal armour, but she wouldn't need that anyway.

She needed to do this; she needed to prove to her father and to Pepper that she was smart and she could do something worthwhile, to be helpful. By the next morning she had everything she needed. She didn't see the point of waiting, so gathering up her things she packed them neatly into a small case before heading up the stairs and into the main living area. There was Pepper talking to a young lady dressed only in a shirt. Minnie wasn't stupid, she knew how father acted, how he picked up women and dropped them quickly, she was used to it by now.

"Good morning Pepper!" she said bright with a smile. The woman turned to look at her. She had short dark hair and wasn't the normal person her father went for, he normally liked blondes. "Hey," she added as a friendly greeting.

"Hello." The woman replied, obviously a little uncomfortable, but Pepper gave her a warm smile.

"Good morning Minnie, have you been down there all night?" Pepper had always been like a mother to Minnie, unlike Tony; they had never argued and always got along.

"Yeah," Minnie smiled and held up her case, "Secret experiment!" she said excitedly, wanting to tell Pepper but also wanting to keep it a surprise.

"Is Tony down there?" the young woman asked suddenly and they both turned to look at her.

"No. I don't know where he is." Minnie said politely before waving neatly, "I'm going to be in my room. Please don't come in Pepper, and tell daddy not to either!"

Pepper opened her mouth and looked like she was going to protest but Minnie was around the corner, running towards her room before she could say anything. She shut the door quickly and locked it before rushing over to her neatly organised desk and propping up a large mirror on it. She asked Jarvis to shut the blinds and turn off the lights except for a single lamp which would serve as her surgery lamp. She knew that this was going to be the weirdest thing she would ever do, but she was curious and compelled to do it. She knew the area of her brain she needed to work on and she knew that it was pretty easy to get to. It was by her hair line, it would leave a small scar but not too noticeable. Finding the correct serum she pushed the needle into her forearm and waited for five minutes until she knew it would have the correct effect. Numbing specific areas of her brain and protecting herself from the pain and the possibility that something could go wrong. The micro-chip and the serum were ready; all she had to was insert them. She leant towards the mirror as if she were about to apply makeup before slowly, carefully, making the first incision. The serum had also been designed to stop blood flow to certain areas meaning that she didn't have to make much of a mess. There was a little blood but she mopped it up quickly.

And there was her skull.

Fear mixed with excitement and adrenaline pumped through her. What was she doing?! She was a thirteen year old girl planning on performing brain surgery on her. But she'd come too far, and she knew she could do this. Gently picking up the drill she made four careful cuts, outlining a tiny square, barely the size of a coin. She knew that little bit right there could be changed to be able to control every little part of her body. It would mean she would be able to control her senses, her blood-flow, and her pulse. Every tiny detail.

She gently picked up the syringe and after taking a deep breath she pushed it into the precise spot in her brain. Wincing slightly, although not from feeling the contact, she injected the serum. That would mean that her brain would accept the new orders she was going to give it and she quickly injected the micro-chip into the correct place. Eager to seal her head back up she was careful but swift in replacing her fragment of skull and using the medical glue she secured it in place. Once it felt completely secure she gently pushed the flap of skin up over it and began to stitch it back up tightly. Once she was done she felt incredibly proud of her work, the stitches were invisible and barely noticeable. The scar was smaller than she was expecting and she allowed herself to lean back in her chair and grin at herself in the mirror. She felt wonderful at having achieved a, fairly small in her opinion, but a surgery none the less, in her own bedroom.

Jarvis brought up the lights and opened the curtains as Minnie walked into her bathroom to wash her hands.

"I must say I disapprove whole heartedly with not telling your father about this." Jarvis said to her but she hushed him.

"You're a computer programme Jarvis, you don't have a heart. You can't tell him, I'll tell him myself once I'm done. He's gonna be so proud of me."

"As much as I would like to believe that Miss, I do believe that won't be the first feeling to come to him."

"Oh hush Jarvis, are you not even the slightest bit proud that I managed to do that without killing myself?" she asked, shaking her hands to try and relieve some of the effects of the serum she'd injected to be able to do the surgery in the first place.

"I am extremely proud Miss, I would not appreciate having to announce to Miss. Potts and Mr. Stark that you had been killed attempting to operate on your own brain."

"Why do you always have to be so pessimistic? Oh wait, I forgot my dad designed you." She said walking back through to her bedroom. "Now for the tricky part," she said, both to herself and to Jarvis. "Now I have to cut into my bloodstream without bleeding out."

"I strongly advise against this. Or at least hire a medical professional. Perhaps I could…?"

"No." Minnie cut him off sternly, "I'm going to do this myself." She sat back at her desk and took out the surgical knife, and the first syringe. The easy part was locating the correct vein and injecting the liquid, she did it easily. But then she had to cut a large, deep cut across her forearm, exposing the vein. Then, holding open the skin, she made the tiniest incision into the vein before quickly implanting the chip. She then quickly unscrewed the cap of the surgical glue before rubbing it over to seal the vein wound. It worked. She grinned to herself as she sewed up the wound across her arm. This cut was a little more obvious than the one on her forehead and she thought she could hear Jarvis sigh with relief.

"You better not have told daddy." Minnie said and Jarvis replied wearily.

"I wouldn't dream of it miss, I know that you know how to shut me down and put an encryption on me."

"Exactly." Minnie replied with a triumphant grin. "One down, three to go." She repeated the procedure three times, once on her other arm and once on each leg so it was surgically implanted in four areas of her body. She smiled at herself in the mirror. She'd done it.

"Wanna try it out?" she asked Jarvis excitedly. He didn't reply.

Desperate to sample her new skills she ran out the door from her bedroom to the beach and down a flight of stairs. Once on the sand she held up her hands and using the new micro-chip in her brain she ordered them to work. Two jets of brilliant white light shot from her palms, burning the sand in front of her, she moved her arms nervously, willing them to keep going. They did as she requested. "Oh my God." She muttered to herself. She told them to stop and they did. There was a slight burning sensation in her palms but nothing too serious, she examined the palms of her hands but there was no obvious scarring, they were just a bit red. She let out a light laugh.

Sitting down she extended her legs and willed them to work the same way as before. Suddenly she shot backwards and hit the face of the cliff. Telling them to stop she sat up groaning. That hurt, a lot. Rubbing her head and back she realised she needed practice, but it was alright. She'd done it. Even her senses seemed better, she could smell the detail of the salty sea from back here, she could see the shimmer of each sun beam on the ocean, and she could feel the smallest breeze playing with her pigtails. She smiled to herself and rushed back up the stairs to report to Jarvis.

"Jarvis, Jarvis guess what?!" she exclaimed as she ran through her door but cut short as she saw her father examining her desk.

"My apologies Miss Stark, your father over-rode my protocols after he heard from Miss Potts that you'd disappeared in here and not returned."

Tony's eyes moved from her desk, which had a significant amount of blood smeared across the work-top, to her and looked her up and down. His eyes found the new stitches and scarring on her bare forearms and an expression she couldn't quite work out rested across his features. Slowly, he walked over to her bed and sat down heavily.

"Something you're not telling me?" he said quietly, for the first time in her life, Minnie was scared. She hadn't practised enough; she wouldn't be able to do this without looking like a fool. She took a deep breath and stared at the floor.

"It works." She said softly and he looked confused.

"Minnie, if you're unhappy you can just talk to me… Or Pepper, she'll always be there to…"

"What?" Minnie interrupted, confused herself now.

"The… cuts." Something clicked in Minnie's head.

"No! No, it's nothing like that! Look I'll show you!" she said grabbing his arm excitedly and dragging him down to the beach. She took a deep breath and looked down at the sand before telling her hands to shoot the bolts. Her brain obeyed and she watched Tony's face take a moment to register what was happening. She stopped it and looked up at him expectantly. He paused for a moment before grabbing her face and pushing her hair back to see the stitches, his hand pushed over the area she'd performed the surgery and it hurt. She yelled out in pain and pushed his hands away.

"Who helped you?! Was it Pepper? It was Pepper wasn't it!" he was angry, upset that he hadn't been told what was going on and that she'd hurt herself to do this.

"No! Pepper had no idea!" She protested, "I did it myself."

"You can't have done."

"Well I did. Why can't you just be proud of the fact that I managed to do this? Yeah it hurt a bit but its fine. Jarvis was supervising me. If anything had gone wrong he would have told you immediately, but I did it. Me." she looked up at him, her eyes filling with tears. She'd wanted so desperately to make her father proud but he just seemed angry. Almost at once his expression softened and he put a hand on her shoulder.

"No… I am proud. That is pretty cool. I just have a suit. But you can keep this on one condition; you let me train you how to use it properly." He said and she looked excited.

"Yes! I agree! Thank you daddy!" she tried to hug him but he kept her at arm's length, patting her awkwardly on the shoulder. Every day she reminded him more of her mother; it pained him a little bit every time he even looked at her. She looked a little taken aback but knew that the hug had been a bit of a long shot. The pats on the shoulder were rare enough, it was very rare that she got any affection at all from her father, after he'd been kidnapped he'd been so happy to see her that he hugged her, but it hadn't really happened since then.

….

Weeks passed and slowly but surely, both Minnie's and her father's skills built up until they could both fly and have a little control over it and they worked out how to use their new skills to good use. Once Pepper found out she was a little wary to give her approval, Minnie was a child. She knew that she had to confront Tony about her fears and so she pulled him away from Minnie.

"Mr. Stark, can I talk to you for a moment?" she asked politely and when he joined her outside the garage he sat on the stairs, a little tired from the training. "I know it's not my place to say, but I don't think that what you're teaching your daughter is a good idea."

Tony considered it for a moment, nodding to himself before looking up at her, "Why not?"

"Because she's a child."

"And? I think she has a right to be able to protect herself."

"But not like this, I really disapprove of how you're encouraging her to behave like this!" Pepper said, she was getting emotional now.

"Pepper, she's my daughter, I think she's a smart kid who can do what she likes. And if this is what she wants, I'm gonna support her." Tony said this as he stood and walked back into the garage to continue working with Minnie. Pepper stayed where she was, watching them sadly. As Minnie had grown up Pepper had been like a mother to her. She'd cared for her and loved her and treated her like she would treat her own daughter. Because that's what she saw her as, her daughter. And it pained her to see her daughter putting herself in harm's way, just to impress someone it was impossible to impress.

A/N: Okay, I have the story in my head for the Avengers part and its killing me that I can't write it yet! I will make it as quick as possible I promise! Any reviews would be lovely thank you!
