A/N: Yeah, this was supposed to be only a one-shot, but some people requested (kinda…?) to continue. I am also interested in this idea and was debating on if I should actually write more of Petra's story, so I decided to continue this, at least through to the end of Civil War. It's going to be a three-part story.

Hope you enjoy! :)

02. Stark Internship Retreat

When she agreed that she would go to Germany with Tony Stark, Petra did not expect it to be right then and there. So she was baffled when Tony told her to pack up and went out the door to tell Aunt May that Petra needed to leave in an hour. Knowing how protective her aunt is, Petra was quite surprised to find herself sitting in - probably one of many - Tony's car an hour later. It took some effort for her and Tony to convince May. He told her that Petra was now going to be his intern and that she needed to attend the internship retreat for that matter. Aunt May, although she did not say it out loud, was clearly not fond of the idea of Tony Stark taking her only niece - it probably had to do with the playboy nature Tony was famous for. Tony had to assure her over and over that Petra would be in no harm, either from him or anyone else.

The combination of Tony's genuine, heartfelt assurance - something that gave off very reassuring feelings - and Petra's eager eyes, Aunt May reluctantly allowed her, under one condition that Petra was to call her whenever she was able to.

Once they got the permission, Tony had Petra pack her things immediately and personally escorted her downstairs to his car - the 'really crazy car parked outside' - and had Petra get in. He sat next to her, and the car drove out of the parking lot.

They headed to the Stark Tower in the middle of the city. Once they were in the basement of the building, Tony told the driver to take her to the airfield.

"This is Happy, and he's going to be your guardian while in Germany," explained Tony.

"Hi, Happy," Petra offered. "I'm Petra."

Happy looked at Tony as if he could not believe the situation.

"This kid?"

"Yeah. Take her to Berlin and meet me there," Tony said. He then turned to Petra. "I have to take care of something first, so you go on with Happy and I'll see you in Berlin."

"Okay," Petra said.

"Alright."

With it, Tony got off the car and headed into the building. Happy huffed in what seemed to be an annoyed manner and turned the car to get back outside.

It was boring to sit still in the car, and Petra had to admit that she was very excited to fly to Berlin to help none other than Tony Stark - her lifelong hero, the one who had saved her years ago at the Stark Expo. So she decided to record the precious moment. She pulled out her phone and tapped on the red dot on the screen.

"Okay, so…. This is Queens, New York, and I'm currently on my way to-"

"Who are you talking to?"

Petra turned her head towards Happy. She was holding a camera, which was now taking in the man who was throwing a disapproving look at her through the room mirror.

"No one…?" She answered. "Just making a little video."

"You know you can't show it to anyone," said Happy.

"Sure," Petra replied. "I know."

"Then why are you narrating it?"

"Just for fun."

Happy just huffed and put on his sunglasses. Petra decided to strike up a conversation with the guy.

"So…. Happy? That's not your real name, right?" She asked. "Why do they call you Happy?"

She did not get an answer as the window to the driver's seat rolled up and was left alone in silence.

It didn't really offend Petra in any way. In fact, she was kind of used to getting rejected. And most importantly, she was too excited to care. She was about to ride an airplane for the first time in her life. And on a private jet, for that matter.

Once they reached the Stark Industries private airfield, Happy and Petra got on Tony Stark's private jet. Happy seemed rather grumpy and irritated as he mounted all the luggage on the plane, while Petra energetically and enthusiastically looked around the inside of the plane, recording everything she saw with her phone.

"No pilot?" She exclaimed when she saw the empty seats in the front. "Oh my god, this is so cool."

When she returned to the passenger seats, Happy was sitting on one side. Petra just absent-mindedly sat down in front of him, facing the man.

"Is that where you're gonna sit?" He asked, in a rather curt tone.

"Am I not allowed to sit here?" Petra asked cautiously.

"Is it your first time on a private plane?"

"More like first time on a plane."

Happy groaned as he leaned his head backward. He didn't say anything else as he got up and walked over to another seat.

The 9-hour flight to Berlin, Germany was spent doing homework, reading, taking photos, watching Happy snoring, and recording more videos. It was just something that Petra could not help. She just didn't want to miss anything from the greatest adventure of her life - especially since it was the very first time she was abroad. Even though she did not have enough time to have a good look around the city, due to the urgency of the situation, she was no less thrilled.

By the time they reached the hotel they were staying in, Happy had to practically drag Petra in order to have her keep up, for she was so easily distracted by everything on the street. But then when she saw the hotel building, she was instantly awed by the grandeur and luxuriousness of it - after all, it was a 5-star hotel. Happy hurriedly and brusquely guided her to their rooms. He handed her the card key after opening the door and getting inside with her luggage.

It was a luxury suite.

"Oh my gosh, I get a suite?" Petra breathed out.

"Hurry up, we don't have time," said Happy. He had placed her baggage inside the room and stepped outside. "Suit up."

Petra went into the room. Everything looked so expensive and shiny that it almost felt surreal for her. She slowly placed her backpack on the couch on the bed while her eyes drifted from one object to another. She just kept looking around the room until a knock brought her back to reality.

"We're leaving in 10! Get ready!" Happy's voice came from behind the door.

Petra took her suit out of her backpack and changed into it. Before putting the mask on, she untied the ponytail she had. She brushed her hair, neatly gathered all strands of hair, and tied it into a tight bun. She checked herself in the mirror, staring right into her own eyes.

"You got this, Pettie," She muttered to herself. She took a deep breath and was about to put on the mask when Happy walked in. He gaped at her.

"What the hell are you wearing?" He asked.

"Uhm… my suit…?"

"Where's the case?"

"Case? What case?"

Happy sighed irritatedly and opened a door that Petra had simply assumed to be a closet. She was amazed when it led to another room with a desk and couches. On a coffee table in front of the couch was a metal suitcase. She approached it and found a note.

"A minor upgrade," she read. She placed the memo aside and opened up the suitcase. The moment she unbuckled it, the case automatically opened itself up.

A neatly folded red-and-blue suit was presented before her eyes.

"What the-" Petra exclaimed as she gaped at it. "Oh. My. God."

"Put it on," said Happy indifferently.

"Is- is this for me?" Petra turned to Happy and drawled in shock. She could not get over that it looked so cutting edge.

"We don't have time. Let's go!" Happy urged before turning around and left the room.

Petra looked back at the suit once again. She tried very hard not to squeal in excitement.

"Dang," She squealed to herself. "This is insane!"

"Alright, I've run out of patience," Tony's voice said from afar. "Underoos!"

"And that's my signal," Petra spoke into her phone, setting it aside. "Showtime."

She swiftly shot a webbing at a tall lamppost from her wrist and soared into the air, using the momentum to shoot forward. She flipped mid-air as she flew over Captain America and his team, shooting webs from one wrist at the very famous shield and pulled it towards her while webbing both his hands together with the other. She then held the metal shield - and she could not express how cool it was to hold Captain freaking America's iconic shield - and landed quite heroically on a large container, although a bit shakily. She slowly looked up to find everyone's eyes on her.

"Nice job, kid," said Tony. Although it sounded like a compliment, he sounded gravely serious.

"No problem, Mr. Stark!" Petra chimed in, saluting with two fingers. "And thanks for the suit! It's really cool. I'm not really used to it yet, but still."

The new suit was beyond awesome. The lenses on the mask adjusted according to the movement of her eyes, automatically shifting the level of focus. There was a hole in the back of the mask for her hair, and a hood to put on outside the mask so that she can cover up the hair as well. The whole suit fit right on her body like her second skin, allowing more natural and easier movements. It was even very convenient to put on, for with one touch it comes loose and baggy. It was true that she could not hide her gender anymore, with the suit revealing her body shape and all, but she never did intend to hide it in the first place, so it was not a problem at all.

"Right, we don't really need you to start a conversation," Tony said sternly.

"Oh, okay."

"You did a good job," Tony said.

"You've been busy," Captain America said to Tony.

"And you've been a complete idiot," Tony replied. He seemed to be trying his best to suppress frustration and anger. "Dragging in Clint, rescuing Wanda from a place she doesn't even wanna leave, a safe place! I'm trying to keep- I'm trying to keep you from tearing the Avengers apart."

Wow. Petra was really absorbed in the scene in front of her. She had known about the incident in Lagos and Sokovia Accords. She also has found out through social media about how Captain America seemed to be having a problem with the government - there were pictures of him being arrested in the middle of a highway, along with some other people like Falcon and a new guy in a black cat-like suit (who happened to be at the site currently). Still, to see Iron Man and Captain America, two of her favorite team of superheroes, having an argument right in front of her eyes was something.

"You did that when you signed," Captain America answered calmly.

"Alright, you're gonna turn Barnes over and come with us, now! Because it's us, or a squad of JSOC guys with no compunction about being impolite."

There was a moment of silence as Captain America looked away from Tony. Tony also waited quietly for the captain's response. It was probably not what he expected, however, when Captain America suddenly raised his hands high. Then an arrow flew out of nowhere, ripping through the webbings on his hands. Tony immediately covered his head again.

"Alright, Lang," Petra heard Captain America mutter.

Petra's so-called Spidey sense picked up something on the shield she was holding.

"What the-"

Before she got the chance to finish, that something turned larger and kicked her in her chin. She fell backward with a squeak, losing both her balance and her grip on the shield. It was taken from her hand in an instant.

"Wha- What the hell was that?" Colonel Rhodes asked in a baffled voice.

"I believe this is yours, Captain America," she heard a voice say.

From then on, everyone broke into action. Iron Man set off to get Maximoff while the guy in black ran off saying, "Barnes is mine!"

Captain America started off by hitting War Machine with his shield. Petra, not sure how to intervene, hesitated but eventually decided to ask directly.

"Mr. Stark?" she said into her comm. "What should I do…?"

"What we discussed! Keep your distance and web them up," he answered.

"Got it!" She immediately set off running towards the airport building.

A/N: Thank you all for reading! Please, feel free to leave your comments and reviews.

I especially need your opinion on this, for if there are people wanting more, I might continue Petra Parker story all the way through Homecoming as well. Please, if you guys want more, tell me in the comments.

Also, if you like the female Peter Parker story, I am actually also working on a female Peter Parker story, which is based loosely on MCU/Tom Holland Peter Parker and has girl Peter as Tony's biological daughter. If you're interested, keep a lookout for it as well!

Once again, thank you for reading, and hope you all have a great day!

Best, Lisa :)
