Hey everyone! So, this is an Avengers/Marvel fanfiction. I do not own any of the characters except Charlie. I do not own any of the settings either. I hope you like it! Please feel free to comment with any questions or comments you have :) I'm always happy to answer questions about my books. _

Charlie laced up her running shoes and started running around the track at her high school. Her shoes slapped against the red pavement, her music playing loudly in her ears. No one else was on the track, or even at the school, this late on a Friday night. The lights that usually lit the track didn't turn on as the sun sank behind the skyscrapers that also hid the moon from view. A beep played through her music and Charlie stopped running, sliding into a full open splits in the grass on the edge of the football field and reaching down so that her nose rested on her left knee and her hands wrapped around her foot. She stayed there till the next beep played and then switched legs, then reached down to the middle next. Charlie finished stretching and quickly ran through all of the forms for taekwondo, throwing in a dozen jumping jacks in between each one. She stopped once she reached 2nd dan black belt and began working through karate next, switching arts again once she passes the first black belt form.

Her music paused as her alarm on her phone went off. It was 10:00. Charlie turned off her alarm and finished the form she was in the middle of. She walked over to her large messenger bag sitting on the edge of the track and pulled out her clearly homemade laptop. She unlocked it and the program she had started before beginning her workout popped back up. She quickly checked over the code and smiled. Tony Stark had created his own defensive software for stark tower, including the AI, JARVIS, that ran most of his company. Charlie was looking right at all the coding that made the whole tower tick. She pulled a flash drive out of her bag and inserted it into the USB port on the side of the laptop and opened the file it contained, inserting her code into Stark's. Hitting enter, she began packing up quickly. JARVIS wouldn't be down for very long and it would not take long before Stark realized he had been hacked. It would take him a few hours to figure out where the signal had come from and probably a few days before he realized that it had come from her laptop and not one of the computers in the lab at the school.

Once her stuff was packed, Charlie ran through the city to the back of Stark Tower. She put the scrambler over the card scanner and after a second, slid a fake promotional card through the scanner. The door unlocked and Charlie was inside, ducking into the girls room closest to the back door. She closed the lid on the toilet in her stall and opened her laptop again to the program that she was using to keep JARVIS and the other security systems from tipping off Stark to her presence. She threw the scrambler into her bag and changed into a button down shirt and slacks. She opened a new file and tapped out a relatively harmless virus and inserted it into JARVIS's programming. Owl City started blaring through the whole tower and Charlie smiled, tapping out a second set of code. All the doors were unlocked and the cameras were down. Charlie pulled her ginger hair into a professional looking bun and switched the contacts she wore while she trained for the glasses she usually wore while the code finished working it's magic. She packed up her tech and clipped a fake ID badge to her collar. She switched her running shoes for flats and added a bit of mascara to her lashes and gloss to her lips. She looked like any new intern would.

Charlie left the bathroom and walked further into the building, walking with her head held high, trying to appear like she belonged there. So far it was working and Charlie paused to look at a map of the building in the lobby. Stark kept his suits of armor in a specially locked room in the basement, but Charlie wasn't interested in the already built suits of armor. She located Stark's office on the map and made her way to the elevator and rode it to the floor Stark's office was located on. She made it unnoticed into the office and began looking around in the cupboards and drawers for the plans for the Iron Man suits.

"What are you doing?" A voice asked behind her and Charlie froze.

"Just looking for Mr. Stark." Charlie stood up straight and turned to see who had entered the room. It was Pepper Potts.

"He's not in here. Who are you?" She asked, her hands on her hips and a look that could probably make weaker men wither before her.

"I'm Charlotte, Charlotte Collins, the new intern. I was told to report to Mr. Stark when I got here." Charlie said, tucking a loose strand of hair behind her ear and trying to look sheepish.

"We don't have new interns starting today. And they're supposed to meet with me. Mr. Stark doesn't meet with interns. You want to try that introduction again?" Ms. Potts offered and Charlie dropped her act.

"I'm just leaving." Charlie said and moved to walk past Ms. Potts and out the door.

"Nope," She said and grabbed Charlie's arm, "Mr. Stark is going to want to speak with you."
