Also sorry it took years. (Like seriously, this was requested in November and it's May.)

"Avengers, meet me in the meeting room now."
Fury's voice rang out to all of the Avengers.

Everyone assembled in the meeting room and sat down.

"Now, there is a new HYDRA base. It is more guarded than any other but so far they only have one weapon. From our intel, we have only gathered that the weapon is a young male, about 14 years old and has metal limbs from failed injections. We don't know how dangerous he is but all we know is that he is very dangerous."
Fury said.

Everyone suited up and met on the Quinn Jet.

~~~

"Avengers, Assemb-."
Steve got cut off by the jet rumbling.

"We're here."
Natasha said.

The team jumped of the jet (everyone had parachutes, even Steve because Bucky threatened him) and landed in front of a forest, not to far from the base.

"Romanoff, Buck, Barton and Wilson, you guys will go ahead and clear the hallways. Stark, Banner, you guys will stay here incase any agents get out and T'Challa and I will go and get the weapon."
Steve said.

The team went inside the base apart from Stark and Banner.

"East hallway clear."
Romanoff spoke into her comm.

"South East hallway clear."
Barnes said.

"North hallway clear."
Wilson said.

"West hallway is not clear, very not clear!"
Barton screamed into his comm. (anyone get the reference??)

"Romanoff, Barnes get to Barton and occupy the agents. The weapon is on hallway that is connected to the West hallway so it makes sense that that hallway is heavily guarded. Wilson you will check all the hallways connecting to the West. Make sure no guard gets through."
T'Challa said. (I said hallway far too much)

The others managed to get the hallway clear and T'Challa and Steve got to the room.

"Be careful Steve."
Natasha told Steve.

"Aren't I always careful."

"No, no you're not."
Bucky said.

Steve and T'Challa went into the room. They weren't expecting to see a young boy chained to the ceiling like a piece of dead meat.

The boy had curly brown hair and brown eyes. His entire left leg was made out of metal and his right hand was also made out of metal.

Steve cut the chains of with his shield and T'Challa caught the boy before he fell to the ground.

"Let's get him to the Tower."

The two rushed out of the room and ran to the jet that was waiting for them.

T'Challa placed the boy on the med-bay bed and everyone saw a young looking face.

But for Natasha and, it was a face that she thought she would never see again.

It was her son.

"Natasha? Is it him?"
Clint asked.

"Yeah. Yeah it is."
Natasha breathed out.

"What are you guys talking about?"
Steve asked.

"Budapest."
They both said.

"What about Budapest?"
Sam asked.

"Something happened in Budapest and nobody knows what apart from Natasha and Clint."
Steve said.

~~~

"Well the boy is awake now. You can all go and see him."
Dr Cho said.

"Thanks Cho."
Natasha said and her and Clint were the first ones in.

"Who are you?"
The boy rasped out in Russian.

"I'm Natasha Romanoff Peter. And this is my best friend Clint Barton. Do you remember us?"
Natasha asked.

"Mama?"

"Yes Peter. I'm Mama."
Natasha hugged Peter.

"And I'm Uncle Clint."
Clint said because he was feeling left out.

"I remember Mama stabbed you because you touched her food."
Peter giggled.

"Yeah I still have a scar from that."
Clint lifted his shirt up and showed a small scar on the left side of his stomach.

"You shouldn't have touched my food then."
Natasha said.

"Can you guys tell us what you're talking about?"
Tony asked.

The three had completely forgotten that the others were in the room as well.

"Idiots, meet Peter, Peter, meet the idiots."
Natasha said.

"Hi."

"How do you know him?"
Steve asked.

"I found him in an abandoned building and I adopted him in Budapest."
Natasha said.

"So that's what happened in Budapest then?"
Sam asked.

"Pretty much yeah."

This took forever and I have no reason why but if you guys want to see more of my writing, check out my one shot book (:
