Tony Stark has always been, in his own words, a 'genius, billionaire, playboy, philanthropist', and indeed he was all these things but on top of them all he was the father to someone even greater than himself.

Y/N Stark is, like her father, a genius but she is also so much more than that. She is kind, witty, driven,beautiful and talented at so many things. She was everything Tony could have ever hoped for her to be and more. She was light of his life and the other lives around her.

Contrary to what some may believe, Y/N had not been the product of a one nightstand. Tony had been in love with her mother; they were married young, barely 21,they had been high school sweethearts and after his parents death and taking over ownership of his father's company Tony needed something stable that was his; so he married Y/N's mother and he always had someone he loved to come home to when he was stressed from work. He loved that and he loved her.

3 years later she gave birth to their daughter Y/N and it had been the happiest day of his life he thought of all the things he would do differently from his father,how he wouldn't be so cold and she would always know how much he loved her no matter what. Tony really had never been so happy in his life. This was the first time he felt like he truly had everything he could ever want. That was when it happened.

Y/N was only a few months old when his wife started to act differently. She didn't want to even touch Y/N then she didn't want to see her or hear her and eventually she shut out her husband as she shut out her daughter. One night when the sky was clear and you could see millions of stars in the sky that's when Tony first realized he was never meant to be completely happy. It was so late, he had felt her shift and move from the bed,like she had done many nights before, but tonight she left the room and when she didn't come back for some time he followed her. He followed her right out to the balcony. He saw her sitting on the railing, feet dangling over the edge staring up at the stars, she was calm as if she had done this many times before. He tried to speak to her but she had shut him out again.

"Why are you coming out so late? You could get hurt. Why don't you come back over and I will get us some chairs and we can sit out here for a while and stargaze."He spoke but he knew that she wasn't listening, not anymore.

"The sky is so beautiful. I have been out here many nights trying to will myself to just jump but something always held me back. I would stare at the sky and something just didn't seem right to me, but tonight,tonight is the night. The sky is clear and it makes me see everything clearly. I am a horrible mother and a horrible wife, I can't even look at my own child. I have nothing else I can do."

Then before he could even reach out to grab her arm she pushed herself from the railing of their second floor balcony. He screamed and called 911 but she was gone the moment she hit the ground and he knew it. So from that moment on he decided he needed to be enough of a parent to his little girl for both him and his wife.

And that's exactly what he did. Y/N never wanted for anything, material or otherwise. Tony noticed from a young age she was interested in learning everything she could and so he taught her everything he could and the things he couldn't teach her he hired people to do. She was brilliant and so talented. At the age of 13 she was already creating things and coming up with ideas for things that Tony had never even dreamed about and she was more than just talented with science. She played the piano, she sang, she painted, she wrote poetry and short stories and whenever she had something new to show her father he was always around to see it, no matter how busy he would always made time to listen to her. This gave her confidence and reminded her that whatever she had to say was always important. Tony really was a grade A parent. He loved his daughter more than anything and she loved him as well, they had a good relationship and it always killed Tony to have to leave her behind when he went on trips for the business.

The trips happened more often as she got older. Y/N would stay with Pepper when her father was away and they always had a good time together, the trips were always the same, Tony would leave Friday morning and be back by Sunday night sometimes Monday morning at the latest, so when Wednesday rolled around and no one had heard from her father Y/N became very worried. She knew something was wrongand she was terrified that she would lose the only parent she hadever known.

Tony did eventually come back but he came back almostas someone else. He was the Iron Man now and it was scary to think about Though Y/N and her father still spent much time together he would spend more time working on his suits while she would pursue her passions of music and art and it become less like a parent and child and more like just 2 people living in the same house.

During the battle in New York Y/N had been overseas soaking up different cultures across Europe and when she returned her father seemed to have returned back to the man she had grown up with. He was lovingand affectionate and listened to her describe every small detail ofher travels, not even glancing away from her for a moment. She was not sure what had changed in her father but she was glad to have him back in her life again the way he was before.

When Stark Tower became the Avengers Tower Tony asked Y/N if she would work with him,help him build and create things for the Avengers to which she promptly agreed. She was very talented and she never said no to achallenge, it was the bigger the better in her opinion. She even created the device that revived Pietro Maximoff.

Y/N had been working on a project for years. Something that would change the world and everyone knew it. She had hoped she would never have to use it but everyone knew it was only a matter of time before she would need to stop testing on animals near death because there would be an Avenger who needed it to work. Project S.W.A.T. (Something Witty And Technical) had been in the works since she was 18, no one knew exactly how it worked but it brought people back from the brink of death. Well it was meant to bring people back but so far it had onlybeen used on animals she found around the city. It had only been successful on one cat a few days before the battle of Sokovia and she hoped to have a few more animal trials before testing on a human life. Unfortunately for her, she worked for 'Earth's Mightiest Heroes' who were about to battle a robot army in Eastern Europe.

Y/N had been pacing the floor since the team left for Sokovia waiting to hear any news. This is what she hated about these silly battles and missions, the waiting. She hated not knowing if they were dead or alive, the waiting killed her and she always paced for hours before going up to her lab to tinker. This time was no different. After almost 24 hours of no word from anyone Y/N went up into her lab to mess around with some new designs and equipment for the team. Just as she was sitting down to her computer she heard the roars of the team as it sounded like they were making their way to her lab. She turned to see Steve through the glass door carrying a body and her father right beside him ready to punch in the security code for the room. They rushed in and she finally recognized the body of the Maximoff boy. They had never met but her dad had had a few choice words to say about him when he met him and he looked just as Bruce had described him a few nights ago. Tony began to speak as Steve placed the twin on Project S.W.A.T..

"This works right?"Tony said quickly in reference to Project S.W.A.T.

"So far it has worked once on a cat I don't know if it will work on a human if that's what you're asking."

"Well if you don't try he is going to die anyway and his sister is right outside this room and he is her only family. You are the only person who even has a shot at saving him so she is counting on you to save her only family."

"Fine I will try this, you two wait outside I don't like to be hovered over while I work."

The men exited the room quickly as she adjusted the boy's body on the table. She then turned on the machine and when to the computer typing in a code that made the table start to shake. After a few minutes she could hear deep gasping breaths coming from the table as the shaking slowed to a stop. Y/N made her way over to the boy and stood beside the table as his eyes opened and a confused look set into his features. She took this time to really look at him for the first time. He had a beautiful face and the most breathtaking eyes. She was almost stunned by how handsome this person was.

"What happened? Who are you? I thought I was going to die." He spoke for the first time and she became more enthralled with him. He began to sit up as the team filled into my lab.

"Well you were going to die but Project S.W.A.T. here saved you. I am Y/N Stark and it is nice to finally meet you, I have heard many interesting things about you."

"All good I hope."He said with a wink.

"Actually no all absolutely horrible."She replied with a chuckle as a woman about her age ran up to the man on the table and hugging him.

"Pietro I am so glad you are alive!"The women yelled "How could you be so reckless with your life! You could have died! You would have died if it had not been for Tony Stark's Daughter!" With that the women, who Y/N assumed was the other Maximoff twin, turned to Y/N and hugged her tightly. "Thank you so much for saving my reckless brother's life I can't thank you enough."

"Well..." Y/N paused waiting for a name

"Wanda."

"Well Wanda,you don't need to thank me. I should be thanking your brother for being such a good candidate for Project S.W.A.T.. It was really all him, all Project S.W.A.T. does is enhance the environment and the participant in a way that can save a person's life according to their individual needs. All I did was punch in a few codes. Your brother did most of the work and he should have minimal trauma even though he was clinically dead for almost 4 minutes before he came in."

"I really have no idea what you just said but I still would like to thank you for saving my life." Pietro spoke glancing at the women who had created the machine to bring him back from the brink of death. He owed her his life and if he had to owe someone his life he was glad it was someone so beautiful. He moved off the table and went to walk to the door."Though however grateful I am, I am in desperate need of a shower and some feed and maybe a nap, being dead makes you surprisingly tired."

Steve Spoke up. "I'll walk him to his room, Nat why don't you show Wanda her room and someone call and order a pizza I am starving." Everyone started to file out of the room except for the two Starks. Y/N sat back down at her computer ready to finally work on some ideas for the team and Tony came to sit down beside her.

"You did good today my Light. You can try to avoid taking credit all you want with the rest of the team but I know that this was all you. This was your dream to be able to help people, to bring them back to the people they love and you did it. I am so proud to have you as a daughter, do you understand that. You are so smart and whenever you set your mind to something you do it and of all the things I have accomplished in my life. You are the greatest one. You will never understand how proud I am of you light, and you somehow manage to make me prouder every single day. I love you sweet girl." Tony had tears in his eyes as he kissed the top of her head.

"I love you too dad."

"I know you do. Now abandon this lab for awhile and come downstairs I've missed you."

"I've missed you too dad, no more business trips for a while right?"

"I don't think there will be business trip for me ever again. I think I am just going to hang up the suit and tinker with my girl for awhile." Tony draped an arm over his daughter's shoulder."Besides I need to be around for all the new inventions you are going to create so I can try to at least take some of the credit." The pair laughed as they walked down the stairs and Y/N had never been so happy to hear his laugh when only an hour ago she thought she might never see him again.

Tony never needed a reason to have a party but if there ever was a reason to have a party it would be the fact that everyone had miraculously made it back alive from battling robots in Sokovia. Everyone really was truly revived that other than Pietro,who was able to be revived, no one came back with more than some cuts, bruises and very sore muscles. So Tony decided he would throw a party in celebration of the victory, what he deemed to be the end of the war. Being Tony's daughter, Y/N had been to plenty of parties in her life but this was the first one she was nervous about. With word about Project S.W.A.T. and it's success going around she knew there would be plenty of people who would want to talk to her and be interested in it but, unlike her father, she wasn't much of a talker and she was not ready to answer a million questions only a week after Project Artistry first real success but she was also excited for a party, after so much chaos it would be nice to just laugh and dance and have fun.

She stood in the mirror of her bedroom placing the last Bobby pin in her hair to secure her bun. She had to say she did look lovely. She wore a dress her father had brought back from Italy last year after he missed her birthday dinner for an important business meeting. She hadn't minded, in fact she thought it was a blessing because she would be able to spend more time working on Project S.W.A.T., which at the time killed anything it tried to revive. But Tony felt bad and had brought it back for her anyway. It was sky blue with a deep V neckline, short with pleats in the skirt and she just felt beautiful in it. She wore it with her white pumps and a set of pearls. She really did feel as beautiful as she looked and she was very excited to finally show her father how the dress looked on her not just on the hanger where it's been for a year.

Y/N made her way down the stairs as she spotted her father across the room by the bar with a glass of champagne in his hand talking to Steve and Thor. She made her way across the room filled with mingling people to say hello to her father and possibly get a drink or two before she had to talk to anyone outside the Avengers.

"Hey Dad. Don't you look spiffy." She said giving her dad a quick hug.

"Well have you looked in the mirror because you look lovely tonight my little Light is. that the dress from last you? I knew I made the right choice with that color you look breathtaking I will have to beat the men off you with a stick tonight!" They laughed then Y/N greeted the two men her father had been speaking to.

"Hello Steve, Thor, how are you doing tonight? I mean must not be well you are standing over here talking to the most boring person in the room." She said pointing at her father.

"Things are going well thanks, I was only listening to your dad and Thor argue over which of them has the better girlfriend."

"Oh well that one is easy! It's Bruce I mean he and Nat are a thing now right? So it's not either of them."Together Steve and Y/N laughed while Tony and Thor looked a combination of confused and hurt.

"I'm going to tell Pepper you said that!"

"Go ahead she would agree with me.Whoever dates Natasha Romanoff is the real winner in any situation. She and I have had this conversation before. Speaking of Pepper I thought she was coming tonight, I do miss her terribly."

"She was supposed to be here but you know running a company is unpredictable and she was called out to Europe suddenly this afternoon."

"Alright well when she gets back her and I should go shopping, bring that up next time you talk to her."

"Will do, you know she loves spending time with you. Anyway if you will excuse me I need to go save that group over there from another one of Rhodey's 'War Machine' stories. I'll talk to you later sweetheart." Tony said as he walked over towards his friend.

"So Y/N Project S.W.A.T. really has done a nice job with the Maximoff boy,the way he is behaving you wouldn't know that he was practically dead a week ago." They looked across the room where Pietro was dancing with a girl neither of them had seen before and they were sure he hadn't either. From the look on the girl's face he wastelling a joke or something. He had a smile so big it looked almost as if it could break his face. The way his shoulders looked as he was holding the girl close was enough to send a few unholy thoughts into Y/N's mind but she was quick to shoo them away, afraid his sister might see them and torment her relentlessly. It was nothing more than a slight physical attraction to him, that's what she was always telling herself. Nothing more and nothing less than a one sided physical attraction.

"Well like I said before, I would prefer to have him resting just in case but getting him to sit still is harder than getting you to dance."

"Ha ha Y/N if you wanted to dance with me you could have just asked instead of taking a jab at my old life."

"Okay then Captain, would you comedance with me? It's a slow song nothing to difficult just some swaying you don't need any skills."

"Alright but just one song, if your dad sees he might get ideas and we don't want any of that."

"Of course not, if he sees us dancing he mightget too excited and pee himself. For all the shit he gives you hethinks you are a great guy." They laughed and made their way toan empty space on the dance floor near Pietro and what now looked tobe a different girl swaying back and forth.

Steve took Y/N's hand and placed his other on her hip and she placed her's on his shoulder as they moved to the song they began talking.

"So Rogers, anyone special in your life these days?"

"No I'm starting to think that maybe I am better off just leading the troops.I used to think, when I first woke up, I could just carry on with my life the way it had been when I went under, wanting the wife and kids and a stable life but the world has changed a lot since I was in it last and I'm not really much into today's dating scene, it's too high tech for me. What about you little Stark, you're 21 you should be out dancing or whatever it is kids do these days, but instead you're hulled up in your little laboratory. Are you seeing a special someone that no one knows about?"

"Well for starters Steve today we go clubbing, it's like dancing but with much less grace and skill and even less clothing. It's not really my scene either I would much rather spend my time making new gadgets for the team anyway. I don't have anyone just my computer and the Avengers." She laughed, she had never really thought about dating, sure she got a lot of offers she was beautiful and talented and intelligent but the reason she was asked out were never for those reasons, it was always because she was a Stark and she was not going to go on a date with someone who only wanted her father's money. She had to choose her dates carefully which meant they were very scarce.

"Well you're young still no need to worry about all that. I was just curious because I have noticed at least half the men here gawking at us"
