Serenity Stark

## Biography

### Early Childhood

Serenity is the eldest child of Tony Stark and Pepper Potts, followed by her younger siblings, Anthony Stark, Jason Stark, Sarah Stark. and Nova Stark. As a child, her parents spoiled her, and she was most certainly born with a silver spoon in her mouth. She got anything that she asked for, and, even though Tony said he never played favorites when it came to his children, he definitely paid more attention to Serenity than he did any of his other children. She attended The Brearley School, an all-girls private school on the Upper East Side of Manhattan, from kindergarten through her senior year of high school alongside her sister Sarah. She thrived in school, especially in her science and math classes, excelling to the top of her class at a very young age. She had many friends, even though she was sure it was only because she was a Stark and kids wanted to hang out with her just because of who her father was, but she still enjoyed having friends.

   People would say that the Stark kids were privileged, and they were, of course, but Serenity and her siblings made it their mission to not flaunt the wealth of their father. Serenity kept that promise, for the most part, only pulling out the "Do you know who my father is?" card when it was beneficial to her. Using that got her out of a lot of trouble during school, like detentions and speeding tickets. Most people knew that Tony Stark was her father, and some people didn't believe her when she told them. Sometimes Tony would come and pick his children up from school just to prove a point, and Serenity laughed when she saw the stunned faces of her peers as they watched her get into the backset of Tony Stark's fancy car.

When she reached her high school years, she continued to excel. She was popular, with a large group of friends and as the captain of the cheer team from her sophomore to senior years. During her junior year of high school, her father went missing, and she missed almost three weeks of school because of it. In fear for the safety of her children, Pepper pulled Serenity and all of her siblings out of school until she knew that Tony was safe and that the people that took him weren't going to be a threat to their family. Shortly after that, Iron Man emerged, and Serenity was the only one out of all of her siblings that knew her father was Iron Man from nearly the very start. She helped her father out with designing his suits, and she withheld Tony's secret identity from her siblings, the rest of them learning the truth when he announced that he was Iron Man at a press conference almost a year after she had found out.

Serenity graduated high school at the top of her class as Valedictorian, and went on to study Biology and Engineering at New York University, and she now has Master's degrees in both fields.

### Stark Industries

From a very young age, Serenity had always been involved in her father's business. She would attend meetings with her mother, not wanting to stay with the nanny that her mother had hired and wanting to learn about the things her father did for work. As she got older, she became more and more involved, and she soon became one of the faces of Stark Industries.

Out of all of her siblings, Serenity was the one that had the most involvement and connections with the family business. She worked alongside her mother on all company affairs, and she loved every second of it. Her younger sister, Sarah Stark, was involved with the business for a little while, but she soon left Stark Industries when she was eighteen, wanting almost nothing to do with it and her family, for the most part. Serenity also helped the company with weapons design and where to take things, and she was always happy to give her input on things whenever she could. After college, she used her Engineering degree to improve the things that Stark Industries was already creating, and she developed may new things for the company. Her mother enjoyed having at least one of her children still involved with the family business, and she loved to see her eldest daughter at work. Pepper and Serenity were a force to be reckoned with, and with all of the ideas that Serenity had swimming around in her brain, she was virtually unstoppable.

### Joining the Avengers

When Serenity was seventeen, her father approached her and asked her if she wanted to help The Avengers on a mission. Of course, she jumped at the chance, and that was how Serenity found herself on a S.H.I.E.L.D. helicarrier above Sokovia. She worked alongside Maria Hill and Nick Fury and the other members of S.H.I.E.L.D. aboard the aircraft in stopping Ultron from destroying Sokovia and parts of the rest of the world, and she also assisted in bringing citizens onto the small passenger ships to safety. Before that, she found herself back at Stark Tower, trying to stop Wanda Maximoff and Pietro Maximoff from getting a hold of whatever Ultron was trying to build with the help of the Mind Stone, which later turned out to be Vision. After that, Serenity was a part of The Avengers more and more, assisting them with anything they may need, which included building and upgrading suits and weapons for her team.

   Her father helped her design her own suit when she was eighteen. It looked similar to one of Tony's, and the colors of her suit were silver and purple. People who saw her fighting alongside her father called her "Iron Lady", but Tony called her "Scout". With that suit, she was able to accomplish more and more with The Avengers, and it made her father feel a little bit better about her going out into the field and facing something potentially dangerous.

### Serenity and Her Siblings

Being the oldest, of course, she was there when her three younger siblings were born. When they were younger, all of them were so close that they were virtually inseparable. The only time the two sisters weren't with their two brothers was when they went to school, since Serenity and Sarah went to an all girls' private school and Jason and Eddie went to an all boys' school. They all spent a lot of time together, whether it was joining their parents on business trips or just being at the house together all the time. They were all very close and Serenity loved her younger siblings and would protect them with everything she had.

But, as they all got older, they began to drift apart. Anthony Stark was the first to break off from the family following an explosive and physical fight with their father. Eddie hadn't gotten along with Tony in years, due to the way he treated him and their youngest sister, Nova Stark. Eddie and Tony fought constantly, the eldest son dealing with years and years of verbal abuse from their father until one day he had enough. After the fight, Eddie packed his things and left, moving to New Jersey and never looking back. Serenity tried her best to keep in touch with him, but the phone calls became less frequent and the text messages went unanswered, and communication with her brother eventually fell off all together.

When Serenity was thirteen, Tony came home with a little girl one day. Serenity was confused, but Tony then told them that this girl was their sister, and her name was Nova. She was a product of a relationship that Tony had gotten into when he was separated from Pepper, and Serenity could tell from the moment this little girl was brought into their lives that her father wished that she didn't exist. Eddie was the first to approach Nova and try to make her feel welcome, no matter how much their father tried to make her feel like she wasn't wanted. Serenity watched as he basically neglected his youngest daughter, and it was the job of Serenity and her siblings to take care of her when her father refused to. Pepper didn't like Nova, at first, since she was born from a relationship that wasn't with her, but she soon warmed up to the girl, taking care of her like a mother would for their own child. Due to the age gap between Serenity and Nova, she found it a little difficult to get along with her and try to relate to her. She tried her best, but she still loved her and cared for her like she would with the rest of her siblings.

    As the years went on, Jason Stark was the next to distance himself from the family. He stopped having anything to do with Stark Industries, and he was barely around HQ anymore. He still spoke to his sisters and his mother, but he had cut off all communication with his father at that point. In retaliation, Tony cut Jason off financially, and he moved away from the Compound soon after that, moving into the city. Sarah Stark never left HQ, but she was still distant when it came to speaking to their parents and with Serenity. Sarah always said that she hated the way that Tony put Serenity up on a pedestal and treated her differently than her siblings, treating her like she was better than his other children. Serenity tried to tell her sister that that wasn't true, but Sarah was adamant about it. Nova also didn't leave HQ, but she was also distant from Tony, Pepper, and Serenity. Serenity watched as her youngest sister tried so hard to gain their father's approval, ever since she was a little girl, but Tony still treated her like he didn't want her to be there, like she was a burden, and Serenity's heart ached for Nova. But, she never did anything about it, and she hated that she didn't step up. She felt like she couldn't stand up to her father, no matter how many times her siblings told her otherwise. She was afraid of him, and she was most afraid of disappointing him.

By the time Serenity was twenty-three, her family was fractured. She hadn't spoken to Eddie in almost three years, both Jason and Sarah had left the Compound and barely spoke to her or their parents, and Nova always gave her the cold shoulder. Serenity became a different person after her family had separated, closing herself off and becoming colder than she used to be. She wanted so desperately to fix her family, but she knew that wasn't possible. She knew there was nothing she could do to try and bring her family back together, and she hated every second of it.

It was obvious that Serenity was treated differently compared to the rest of her siblings, no matter how much she tried to ignore that fact. She ate up every bit of praise that her father and mother sent her way, and she wanted nothing more than to gain the approval of both of her parents. She wanted so badly to keep up the image that she was the perfect daughter, and she did everything that she could to get words of praise and affirmation from both of her parents, but mostly her father. She had set herself incredibly high standards, and she found it difficult to keep up with them sometimes. When she would find herself in news articles alongside her father, the headlines dubbing her as "Tony Stark's Golden Child", she found herself picking apart every little piece of herself, down to every last molecule in her body. Also being a cheerleader in high school, and the captain of the team, she knew that appearances were everything, especially when she was the daughter of Tony Stark.

In her junior year of high school, Serenity had developed an eating disorder without even realizing it. She picked apart her body and her appearance every time she saw a photo of herself, and she began skipping meals and making herself throw up if she did eat. She hated herself, and tried her best not to let it show on the outside. Her parents were both too busy to notice that their daughter was hurting, and whenever her siblings would ask her if she was okay, she would just brush it off and tell them that she was fine. She didn't want anyone to know that she was falling apart, that she was broken in anyway. She needed to keep up the image of being Tony Stark's perfect daughter, at the detriment of her mental health. Depression and anxiety also followed her, and she didn't know how to deal with it or talk about it, so she just dealt with it on her own, like she always did. But, her brother was observant, and Anthony Stark was the first one to clock that something was wrong with his older sister. Serenity broke down in front of Eddie, finally telling someone about everything that she was dealing with. Being only thirteen, Eddie knew that he couldn't do much for Serenity, but he knew that he would do his best to try and be there for his sister as much as he could.

It took a long time, but Serenity finally came to her mother and told her what was going on, and Pepper was so heartbroken that she didn't know that her daughter was suffering, and she wished that Serenity had told her about it sooner. After a long conversation, Pepper helped Serenity start going to therapy and begin the recovery process of her eating disorder. Andrew Rogers was also a big help, making sure that Serenity was eating well and covering or removing the nutrition facts labels on all of the food that was in the Compound kitchen. Andrew made her feel beautiful and worthy and loved, so it was no surprise to either of them when they began dating. She still struggles with it sometimes to this day, but she's getting through it one day at a time with the help of her friends and family.

### The Sokovia Accords

Serenity was on a mission in Lagos with Steve Rogers, Natasha Romanoff, Sam Wilson, Wanda Maximoff, Caroline Rogers, Alexander Barnes, and Cooper Barton, trying to stop Crossbones and his team from breaking into the Institute for Infectious Diseases and steal a chemical they planned to turn into a bioweapon. She watched as Steve fought him off, trying to stop him from blowing himself up with a bomb strapped to his chest in some kind of suicide mission, when Wanda used her powers to stop him. She lost the control she had on him, sending him into the air and into a building, causing the bomb to go off and blow up half of the large building. It resulted in the deaths of fifteen people and left hundreds of people wounded. A month after the events in Lagos happened. Thaddeus Ross and Tony Stark approached the Avengers, Ross explaining that due to the recent disaster in Lagos, as well as what happened in New York and Sokovia, that the Avengers could no longer operate privately, and thus the Sokovia Accords were presented to them. Serenity initially didn't want to sign them, but her father convinced her, telling her that it was the right thing to do. She hated that she still folded to the whims of her father, still vying for his approval and affection after all of these years.

The team was completely divided, several people refusing to sign the Accords: Cooper Barton, Clara Barnes, Sam Wilson, Harold Banner, Steve Rogers, and Caroline Rogers, to name a few. Andrew Rogers also refused to sign them, and Serenity and Andrew fought about it before he had decided he had enough, breaking things off with her before they could fight about it anymore. Those that did sign the Accords included Alexander Barnes, Natasha Romanoff, Tony Stark, Vision, James Rhodes, Lila Barton, and Serenity. Many of the Avengers' kids refused to even be involved with the whole mess, not refusing or agreeing to them, just wanting to be left out of it. This included Shiloh Strange, Charles Banner, Nathaniel Barton, and Joseph Rogers.

In the midst of all of the chaos, a video circulated around news outlets of Anthony Barnes—the youngest child of Natasha Romanoff and Bucky Barnes, who had just recently returned to the Avengers after being captured by H.Y.D.R.A. and turned into The Winter Soldier II—killing a government official in New York. She initially though that the CCTV footage was too grainy to truly tell if it was really Anthony that did this, but her father and Natasha were convinced that it was him, Alec telling her that he wouldn't put it past his brother to do something like this, since The Winter Soldier Programming was still in his head and he could snap at any moment. Serenity watched as her father, Natasha Romanoff, and Alexander Barnes followed by an army of SWAT members went after Anthony, trying to capture him and bring him in so he could be arrested. Anthony escaped the Compound in a Quinjet, alongside Bucky Barnes, Andrew Rogers, Sam Wilson, Clara Barnes, Penelope Banner, Steve Rogers, Nova Stark, and Caroline Rogers. This sent Tony into a spiral, and Serenity did her best to calm him down, but she eventually caved and helped him to try and find out where they had run off to, but the GPS tracking in the Quinjet they took had been turned off, the tracker saying that the jet was still in the hangar. Serenity helped her father and Natasha try to locate them for days, eventually finding them somewhere in the Catskills, a GPS tracker that Tony had put on one of the cars they kept at their safehouse near Upstate New York.

They descended upon a cabin in the Catskills the next morning, Serenity watching Alexander Barnes shoot Harold Banner in the neck with one of his tranquilizer darts, and she went after Anthony Barnes while Alec went after Penelope Banner and Nova Stark. She followed Anthony, getting onto the other motorcycle that was in the shed and driving after him. She managed to get close to him, getting off of the bike and aiming her dart gun at him, ready to shoot him, when she was tackled to the ground by Nova. the fought for a moment, Nova landing a few good licks on her before she managed to wrench the dart gun out of her hand, pressing it to her neck and shooting her with one of her own darts. Serenity saw her sister get up and run away as she began to pass out, Alec finding her and getting her out of there before she fully fell unconscious. When she woke up, she was in the medical wing of a S.H.I.E.L.D. facility somewhere in New York City, her father at her side. Tony told her that they managed to capture Anthony and the rest of the people that helped hide them, and that someone was coming in to interrogate Anthony. Once Serenity felt less dizzy and could stand without falling over, she left the medical wing with her father, following him to one of the conference rooms. In the room, she found her brother, Anthony Stark, whom she hadn't seen in over five years. She wanted to be happy to see him, but the moment both Serenity and her father walked into the room, Eddie began yelling at them, telling them that they were idiots for believing the footage of Anthony and that they should be ashamed of themselves. She did feel ashamed, but she didn't let it show, throwing the same cold behavior that he gave her right back at him. Eddie stormed out of the room after a few more minutes, giving both of them the middle finger as he walked out the door. Tony and Serenity left the room again, going to an interrogation room to talk to Nova. Once they were in there, Nova was already furious, throwing the glass that was in her hand at the both of them as soon as they stepped in the room. The two sisters didn't hold back the sarcastic comments, both of them seething with anger and resentment. Tony had to step between the two of them so they didn't start fighting, knowing that the girls could get violent if provoked to do so. After Tony and Serenity tried their best to talk to Nova, she gave up. She already knew that she wasn't going to be any help, but she was a little hopeful that they could get something out of her, to no avail. She threw a rude comment her sister's way before storming out of the room, leaving Tony and Nova by themselves.

While in the conference room, she had a confrontation with Harold Banner when they all gathered around the table to discuss what to do next, ending with Harry grabbing her by the front of her jacket and daring her to start something with him, the girl cowering as she watched his eyes flash green. Eddie pushed Harry back into his chair when she backed away, and Serenity did her best to ignore Harry for the rest of the time. Tony began showing a live video of Anthony Barnes in holding in the basement of the facility, Serenity watching everything unfold from her place in the corner of the room. All hell broke loose when the power in the building suddenly cut out and they lost connection to the camera that was in the room where Anthony was. She watched as Nova Stark ran out of the room, closely followed by Harold Banner, Anthony Stark, Steve Rogers, Bucky Barnes, and Sam Wilson. Serenity followed her dad out of the conference room after waiting a bit, spotting Anthony chasing Harry up the stairs and down the hall. She aimed her gun at Anthony, firing off a few rounds but missing each time. James Rhodes informed them that they had gotten away, and both Serenity and Tony were angry that they managed to escape them yet again.

It wasn't until the next morning that they were able to pinpoint where they were and they found them via the GPS that was in the car they took, tracking them to the John F. Kennedy International Airport. Tony ordered for the airport to be locked down, and then they all met up in the middle of the runway. Serenity stared down at her brother and sister, trying her best to seem angry at them, but, deep down, she was really just sad that this all came to the point that it did. She knew that whatever the end result of all of this was that they would be divided in some way, and she wasn't ready for that to happen. When Anthony refused to turn himself in, the fight began, and Serenity tried her best to fight off Harold Banner, but he was much stronger than she was, sending her to the ground with one kick to the side. She watched as he ran off, tackling Alexander Barnes to the ground to stop him from getting to Anthony Barnes and Clara Barnes, who were running towards a Quinjet at the back of the airport. Serenity tried her best to get up to go after Harry, but she was stopped by Wanda Maximoff, being held to the ground by her powers. She was able to move one of her arms, pulling her gun from her holster and shooting at Anthony Stark while he went to help an injured Harry, managing to shoot him in the shoulder. Anthony, Clara, Nova, Steve, Bucky, and Sam managed to get away, and Eddie managed to get Harry to the ambulance that was parked off to the side where Penelope Banner and Jason Stark were. The fight ended with James Rhodes accidentally being hit with a laser from Vision while he was aiming for someone else, sending him plummeting to the ground straight out of the sky. The team got him onto a Quinjet that was still parked at the airport for them, heading back to HQ.

Serenity was back at HQ for two hours before she got a transmission from Nova containing coordinates and a message from her, saying that Tony needed help and that she was sorry. She was confused, but she went anyways, taking
