Here is my updated and revised and once again im sorry LOVE ME! XD so yeah here it is
For those that dont know this oneshot is about my oc Anastasiya helping her SHEILD recruit trainner friend David teach his recruits a lesson

I take a breath, setting myself into the mindset of my persona. Now I am a sweet innocent teenage girl. I look down at my bubble gum pink top, lime green sweat pants, flowery scarf, and flipflops. I place a sweet smile on my face and nod at David signaling that I'm ready to show those recruits who's boss. We walk through the doors and heads turn to look.

"RECRUITS GET YOUR ASSES BACK IN FORMATION BEFORE I DECIDE YOU NEED TO RUN SOME LAPS!" David yells and the recruits mostly rush to get into formation. I notice all the questioning looks and internally catalog all the slackers.

"What's with the kid?" one of the slackers ask.

"She Mr. Stone is your sparing partner for today, AND BEFORE YOU INTERRUPT ME, yes I realize she is a girl and to you a child I just don't care!"

"If it bothers you so much you can go easy on me." I say with an easy smile as I take off my scarf and flipflops.

"DO NOT GO EASY ON HER! Stone, Wolf, Scott, Donald, Myers get on the mat."David yells, "The rules are if she gets all of you down at once she wins and if you get her down for ten seconds you win."

They walk cautiously up to the mat uncertain if they will actually have to fight me or if this some kind of test. I on the other hand skip my way up to the mat and step inside the circle. I hear the bell ring and allow myself to drop the bubbly persona and slide into assassin mode. I can see the recruits pause for a second surprised by my sudden change. The big one Stone lunges at me I spin out of his way and immediately duck out-of-the-way of the fist I feel coming at my side. I grab the hand and spin him in to the guy who was about to kick at my head, they both go sprawling across the floor.
Another guy runs at me I throw myself into my mom's signature thigh flip but I'm careful not to break his neck. The Stone guy grabs me from behind; I slip my foot behind him and then slam my weight into him causing him to fall backwards and let go of me. I jump up from the ground and look to see that I have one guy standing and the two that got tangled start to get up. I run at the last one standing and throw feign throwing my fist at his face. When he ducks I grab him and throw him into a head lock and use that momentum to literally throw him into the two guys that were just getting up sending them all into the floor. I hear David's whistle blow and I look around Stone is sprawled back-down into the mat, the one I used the thigh flip on unconscious on the floor, and my pile of guys tangled up in front of me.

I look up at David and smile "You might need a medic or two."

"...How?..." a recruit breathes awestruck by what he saw.

"This is the most important lesson you will learn at S.H.E.I.L.D., looks are deceiving. Nothing in this world that you are about to enter is as it seams. There is no black and white in this world. You are walking into a world filled with grey and red. I hope you learned from this demonstration." I say keeping my voice cold and professional.

"Excuse me, miss but who are you?" one of the recruits who never spoke up before asked.

"I'm Anastasiya Barton; yes the daughter of Clint Baryon and Natasha Romanoff." I say smiling.

"I call a redo." I hear the cocky one say from behind me. "We didn't know you were the daughter of two top class assassins or we would have never underestimated you like that."

"That was exactly the point of this exercise you took me on as if I was just a teenager. You didn't even think that I could be anything but that." I sigh.

"I still think that if it was just me and you I would have been able to put you on the ground." He spats.

"In your dreams," I laugh. "Well David I have to go mom wants me to stop for Chinese on the way home."

I sense the punch coming from behind me that was headed without a doubt for my left side in the area of my kidneys. I spin out of the way, grab his arm spin him out in front of me and slam him towards the ground.

"You have a lot to learn before you can even think of getting to my level" I growl. I then flip my hair over my shoulder and glide out of the gym.

Random Recruits' Pov:

When that girl came in the room with David I thought it could be his daughter, she looked so sweet and bubbly in her green sweat pants and pink shirt with her auburn hair up in a sporty pony tail.

Then sir said that some of were going to spar with her I thought he was joking. Then she got on the mat with five of our best guys on the mat with her and she was still bubbly. But as soon as that whistle blew she was a whole different person, it was actually startling to see that level of change so quickly. She took all five of them down in 2min 25sec.

When she said she was the daughter of Natasha Romanoff and Clint Barton it all made sense. She literally was perfectly made for this.

Then Stone attacked her and its like she could see it coming she deflected it so easily and then just walked out. When she walked out though you can tell that she was acting when she walked into the room the first time, this girl isn't bubbly of sweet, no this girl is hard, beautiful and tough. It fits her.
