AN: Okay, so I know this has been done a few times but I wanted to give it a try. First off, I'm am writing this by only going off the movie and what little I've read about the characters online, so please bear with me. Secondly, I know that technically Black Widow cannot have kids, but for the sake of the story, she can. So, this would be AU in that sense. Thirdly, this is my first Avengers story, so I would love to hear what everyone thinks about it and I love getting feedback. I have written numerous Supernatural and Leverage stories so if you guys are fans of those shows I would love for you to check out my other stories as well. Anyways, on to the story.

Agents Clint Barton and Natasha Romanoff stare at the file in front of them. It had been a few years since they started with the Avengers, but never have they imagined those three words coming out of Coulson's mouth.

We found her.

Natasha looks over at Phil Coulson first, studying him, making sure what he is telling them is the truth. It all started in Budapest; with a little too much to drink after a death defying mission and waking up the following morning in the same bed as your partner, your clothes strewn across the floor. Neither one of them, Natasha or Clint, knew how much this would change everything. Not until a couple months down the road when she found out she was pregnant. Seven months later, she gave birth to a healthy baby girl. Natasha glances at the file: Alexandra Daniela Barton. It had been years since either one of them had seen her, sixteen to be exact. Three months after she had given birth, they were attacked and their little baby girl was taken from them. They had searched for her through hell and high water but to no avail. They never even found a trace of her. Not until now that is. Natasha looks back up to Coulson.

"When…?" she begins, but can't voice the question.

"Six years ago," Coulson answers, waiting for the inevitable fallout. Clint's head shoots up at hearing this.

"Six years…?" he asks, his own question not finished. "What the hell have you been doing? Waiting for the right moment?"

"We didn't know…" Phil begins.

"How did you not know?" Natasha asks heatedly, death in her glare. "You found her…"

"I didn't find her. We had an alternative branch in S.H.I.E.L.D. One for orphans," Phil explains.

"You took orphans off the street and made them into mini-agents?" Natasha asks, scoffing at the thought of it. Her mind wanders to her days in the Red Room.

"No. We took orphans off the street and gave them a choice. If they chose not to, they were put in foster homes. The others who chose to do it, were put in the program. I didn't have any information on who was in the program," Phil explains further.

"Then how did you get this?" Clint asks, lifting up the S.H.I.E.L.D. file.

"The program converged with us last year. All of the files were sent over. I was just recently put in charge of it and was given full access. I saw this when I was going through the files," Coulson answers.

"Why didn't they change her name? How is it…?" Romanoff asks.

"Supposedly, that was the name she told us when we found her. Talked to the original handler and he said she had a blanket with the name on it," Coulson replies. Natasha's mind wanders to the purple blanket she had gotten for their daughter. The one she would wrap around her before she put her to bed.

"Does she know?" Barton asks.

"No. I wanted to talk to you two about this first," Phil says.

"When can we see her?" Natasha asks.

"This afternoon," Phil says. "I am telling you this now because we have a problem."

"What kind of problem?" Clint asks, eyeing Coulson.

"An Avenger kind of problem," Coulson replies. "We're having a meeting at S.H.I.E.L.D. at two o'clock. The thing is…"

"What?" Natasha and Clint ask.

"Alexandra is our…informant," Phil says.

"I'm confused," Barton says.

"Her and her partner, Johnny, have recently discovered information about a group of scientists doing experiments on kids, teenagers. To create the perfect superhero. Supervillian. Whatever they're planning. We're not sure yet," Coulson explains.

Natasha and Clint share a look, not liking the sound of this at all. Clint looks over at Phil, mustering the courage to ask the question.

"Did they…? Was she…?" he asks.

"No," Coulson answers, knowing what the parents want to ask, "But her partner, Johnny, he was one of them."

AVENGERS

"So, let me get this straight," Banner says to Coulson. They had arrived at S.H.I.E.L.D. a little while ago and Phil Coulson had just finished explaining to the team what they were going up against. "These guys knowingly made this moody teenage kid into a no-anger management Hulk?"

"Count down from a hundred Banner," Tony Stark says, noticing, as well as everyone else, how the guys' anger is bubbling up. No need to have said Hulk come over for a visit. Bruce closes his eyes and tries his hardest to calm himself down.

"We need to find these guys and bring them in," Phil says.

"So the kid gets angry and turns into a green monster like Bruce?" Stark asks, turning his attention to Coulson.

"Not entirely. They modified it. Made it so he doesn't 'Hulk out'," Phil says. "When he gets angry he gets bigger but still looks human. And he develops the strength five times that of a normal human being. He doesn't feel injuries but if he takes a lethal shot he will die."

"When do we get to meet the two agents?" Steve asks.

"They should be coming up here any…" Phil begins but is interrupted by an alarm sounding. Phil looks towards the ceiling, a worried look on his face. "Dammit."

An agent quickly enters the room and walks over to Phil Coulson, a worried look on his own face. Coulson turns his attention to him.

"Is that what I think it is?" Coulson asks him.

"Yes sir," the agent answers.

"We need to find Barton. Now," Coulson says urgently.

"She's already there sir. She was there when it happened," the agent replies.

"All right, follow the protocol," Coulson orders. The agent nods his head and disappears out the door. The Avengers all look towards Coulson, silently wondering what's going on. Banner speaks up for the team.

"Is that alarm what I'm thinking it is?" Banner asks. Coulson turns his attention towards the team.

"If you think it means Johnny has…" Phil begins trying to find the words for it.

"Gotten angry?" Banner asks.

"Yes. Then, yes it does," Phil answers.

"We should go help," Rogers says.

"That's a bad idea," Coulson says. "The more variables the worse it gets."

AVENGERS

Alexandra walks towards the shooting range, her arrows in their case strapped to her back, her bow in her hand. She hears a commotion coming from the gym just ahead and she slows her walk, curious as to what is going on. Suddenly, there are screams heard and people begin streaming out of the gym, most of them teenagers that were with her back at their original building. Alexandra runs over to the door, trying to peer in over everyone rushing out the door.

"Crap," she mutters, seeing Johnny standing in the middle of the room, his transformation already done. Her eyes narrow at the teenaged boy cowering in the corner, Gregory Nicholson. He was always causing trouble for Johnny and this time, it seems, Johnny wasn't turning the other cheek. She carefully walks into the gym and towards Johnny.

"Johnny?" she says calmly, holding her hands up in placation, having put her bow on her back. Johnny looks over at her, anger evident in his face and nothing else. Alexandra looks over at Greg angrily, seeing Johnny is too far gone. "What did you do?"

Before Greg can answer Johnny shoves the bag out of his way and charges at him. Greg's eyes grow big and he bolts up, running straight for the door, shoving Alexandra out of the way. Alex stumbles slightly but catches her balance. She hears a roar behind her and she turns around in time to have Johnny shove her out of the way and run out the door after Gregory. Alex flies through the air and crashes into the wall, falling to the floor. She lets out a groan and pushes herself to her hands and knees, looking up but not seeing either of the agents. She pushes herself to her feet and runs towards the door. She hits a big red button right before she flies down the hall in search of the two agents, an alarm beginning to blare.

Alexandra runs down the abandoned hallways, everyone knowing to lock themselves in rooms when the alarm sounds. She hears a door slam up ahead and she rounds the corner to see Johnny smash a hand through a door.

"Johnny!" she shouts, running down the hall. Johnny turns at hearing his name, angry at being disturbed. Alex pulls out an arrow and puts it in her bow as she runs towards him. Johnny growls and takes a couple steps forward, hitting Alex in the side and sending her through the door on the right.

AVENGERS

"We can't just leave her to deal with this on her own," Romanoff argues.

"She's done this numerous times before. She'll just get pissed if we intervene," Coulson says. "She gets very protective of the guy."

There is a roar out in the hall and the group turns their heads to look at the door. A teenaged boy runs by and into the open door across the hall, slamming the door behind him. An extremely muscular teenaged boy runs by as well, obviously angry.

"This isn't good," Phil says as he hears Johnny slam a fist into the door. A shout of Johnny's name is heard down the hall and everything goes silent for a second. A figure runs by, but before any of the Avengers can say anything, the door to their room slams open and a body flies in, crashing into the table and to the floor.

Alex looks up, seeing her bow a few feet away, she scurries over to it and grabs it. She looks around, but doesn't see the arrow anywhere. Johnny growls and appears in the doorway. Phil looks around and sees the arrow in the corner, grabbing it quickly.

"Barton!" Alex looks up and sees Phil throw the arrow to her and she catches it, setting it in her bow and shooting. He imbeds itself into the wall behind Johnny, up to the feathers. Johnny lets out and angry yell and moves to run at her. Alex yanks out another arrow and shoots it at Johnny before grabbing another arrow and aiming, waiting. The arrow hits Johnny, letting out enough of an explosion to send him backwards and into the wall. Just as Johnny reaches the wall, Alexandra shoots the last arrow. It imbeds itself parallel to the first arrow on the other side of Johnny. There is a hissing noise and the first arrow opens up and a steel bar appears, strapping Johnny to the wall and connecting to the other arrow. Johnny fights against his restraint but is unable to break it, letting out an angry yell. Alex sighs in relief and sits down on the table. She looks over at Coulson.

"Coulson. Two words. Tranquilizer Arrows," she says, sighing again and making a face as she feels her already bruising ribs.

AVENGERS

"So, do you normally take on moody, "hulked-out" teenage boys by yourself?" Stark asks, looking over at Alexandra, not missing the way Barton and Romanoff continue to stare at her. Johnny had calmed down a short time ago and had left to get changed before joining the meeting.

"Alex is our top Agent in Martial Arts and the Bow and Arrow. Excluding of course the Black Widow and Hawkeye," Coulson says.

"You mean amongst the teenagers," Steve says.

"No, I mean overall," Coulson says.

"Coulson won't let me use the guns yet," Alex says.

"It's against the law," Coulson says for what seems to be the thousandth time.

"You are the law," Alex points out, earning a smirk from Natasha and Clint.

"You can't be older than what? Thirteen?" Stark asks, eyeing Alexandra up. Alex shoots him a glare.

"I'm sixteen," she says.

"Alexandra is…dedicated," Coulson says, giving the two assassins a look.

"No…she's just stubborn. She doesn't like to be doubted. Has to always prove everyone else wrong," a voice says from the doorway. The group, excluding Alex, turn to see Johnny standing in the doorway. He gives Coulson a nod before taking a seat next to Alexandra. "Our handler told her she'd never beat the guys in hand-to-hand so she made sure she could. The guys said she'd never be as good as them at the shooting range so she made sure she was better."

"You must get that from your parents," Stark says, earning a look he can't quite place from Alex. He hadn't missed the name Coulson shouted when he threw her the arrow. One look at her and he knew exactly who her parents were. She looked just like Romanoff, except the blue eyes and brown hair. Those were all Barton's.

"I wouldn't know," she says off-handedly, bringing Stark back to the conversation. "So, should we get down to business?"
