Author note: For this story it will primarily be built up of one shot that will be in chronological order. There may be a few instances where the next chapter will be a direct continuation of the previous chapter. Also, this will follow the MCU timeline and events but with some bits from the comic world as well but more so the MCU. This is a Buckynat/WinterWidow fanfic but there will be hints of Romanogers as well as BlackHawk and of course her brief relationship with Bruce. So I hope you guys enjoy. Please leave reviews if you enjoyed it!

It was early morning and Natalia and the rest of the girls were already awake and geared up for their day of training. Madame B. had told them that there would be a surprise for them today and to bring their best. They always had to bring their "best", nothing else would be accepted. Even at the age of six years old Natalia knew to never half ass anything here and if she did the punishment she would face would make her wish she gave it her all. Natalia, now fifteen years of age, always gave above and beyond. She wanted nothing more than to be the Black Widow. The one who can take down her enemies without batting an eye, complete a mission and make it looks effortless, to leave everyone astounded by her skills and abilities. This also meant not making friends here, which wasn't hard to do. None of the other girls were really here for friendships either, they were all merely raised together and trained together. Nothing bonded them besides just coexisting in this dark cold mansion. You never know who will betray you.

All the girls filed down the stairs and made their way to the training room per usual morning routine. They wore their white t-shirts and black tights with their hair pulled back into pony tails. They stood around the large room that would look normal to any other person. It had floor tiles and wall paneling that you would expect in and old mansion and big curtains to frame the large windows that let the grey Russian sunshine in. Natalia looked around to examine anything that would give away their possible surprise. Nothing gave it away until Madame B. followed by a couple male workers entered the room. The older woman stood in front of the girls with her blonde hair pulled into a bun as usual, wearing her standard blazer and skirt and red lipstick. She looked like a head mistress or a any other business woman. But she was way more than that. She was everything Natalia wanted to be.

"Good morning girls," She smiled. "Today we have a surprise for you as you know. This surprise will help better you and give you the challenge you need in combat." Natalia was still wondering what she could be talking about. It was a mix of interest and a little bit of nerves. You never really knew what they were going to throw at you here.

"So, I will get right to it. Bring him in." She motioned towards the two men who had walked in with her. They walked out the room for just a moment and reappeared with another man. But he wasn't like them. He was a bit taller for one, but the look he had on his face was blank and expressionless. Natalia also noticed that his left arm was in fact metal with a red star printed on the shoulder. He had dark brown hair that was cut short and looked like he actually styled it. He wasn't too bad looking, Natalia thought to herself but soon shook the thought from her her.

"Girls, this is James. He will be helping you train in combat." Madame B. continued. "James is very well trained and will be pushing you to your limits. I expect you to put your best forward and to grow. So let us begin then, shall we?" She smiled and nodded at James.

"Katya, you're up first." Natalia watched as the ice blonde stepped forward with a look of determination on her face. Katya took some steps towards James who gave no indication on what he would do. Natalia watched as Katya got close up and made it look as if she was going to land a blow towards his stomach but faked it out and went for his face. He barely flinched and caught her fist in his metal hand and flipped her down to the ground in one swift motion. Natalia could hear the wind get knocked out the girl who was now gasping for breath. Madame B. called girl after girl to take on their new teacher and each one was bested by him. Natalia watched and tried to observe any weak points or advantages she could have.

"Natalia, you're next." Madame B. called her with a smile.

There was no denying that she had become somewhat of a favorite to her. Natalia stepped forward and brought herself just a couple feet in front of her target. She eyed him carefully as he just stared back with his dark green eyes. She had a plan in mind now. She gave a small grin to her opponent before she made her move. Natalia threw one fist out, he caught and grabbed hold of it like she hoped he would. When he went to flip her like he had one prior she moved her body with the flip and landed back on her feet and landed a punch to his face which stunned him only for a moment but enough time for her to kick him in the center to send him stumbling back a few feet. She ran and leaped hooking a leg over one of his shoulder and one around his torso. She brought an elbow down a couple times onto his head as he struggled to grab a hold of her. Once he did, he threw her and sent her flying towards a wall. Natalia rolled with it and landed back on her feet in a crouching position. They both toward each other, she ducked and slid between his legs turning around and striking a blow to his side. He turned around and grabbed hold of her arm, bending it behind he back. Natalia, not wanting to lose this quickly like the other girls, took a chance and kicked her legs up. Using the momentum of the kick flipped her behind him and she continued the momentum and pulled him with her landing him on his back. However, he was smarter and pulled her down with him. She was laying beside him and acted quickly bringing elbow into his side while he struck her in the face. She rolled to straddle him and land a punch to his face before he flipped them over and was on top of her pinning her arms down.

"Well done Natalia, sloppy, but well done you lasted the longest." Madame B. clapped. James stood up and Natalia followed suit. "Now, I hope this showed you girls how much work you still need. You may think you are strong and quick. But you are not. Not while there are bigger and quicker opponents out there." Madame B. looked on at the girls who looked exhausted and some even had bloody noses. "Now, enough of this. Go get cleaned up for your dance lessons." The girls were dismissed and they started walking out, Natalia was almost to the door when Madame B. placed a hand on her shoulder.

"Natalia, you did very good." She smiled. "I think James has a lot to teach you and I want you to start training with him for an hour after all your other lessons starting tomorrow."

"Yes Madame." She nodded. "I appreciate the extra lesson."

"Good." She smiled and took her hand off the red head's shoulder. Natalia walked out of the room feeling excited for the new challenge brought before her. She new she would be the best Black Widow they have ever seen.
