A/N

Hi guys! I have a few things I'd like to say, before we start. Firstly, I'm not from an English speaking country, so despite the fact that try to check the stories as best as I can, forgive me any mistakes that might occur. ;) Secondly, this is my own creation, so pardon me if the plot doesn't quite fit with what's happening in the MCU or the comics. Also, I'd like to add that it's my first fanfic, so don't be to harsh on me :p

PROLOGUE Russia, 180 km from Petersburg

What she could hear was this odd, crushing noise. She got up as quietly as possible, she didn't want the guards to hear her. The sound of firing guns and screams reached her ears. She came closer to the force field, that was the wall of her cell. Standing there, she waited for what's going to happen. The noise faded and for the moment it was perfectly quiet. Four watchman, who were guarding her, flipped the tabled in the laboratory and hid beside it, waiting. The girl in the cage didn't move. Suddenly, the doors to the lab were kicked out by a man wearing blue tights, blue mask and a ridiculous shield with a star. She knew him. It was Captain America. The guards opened fire at him but he covered his body with the shield, which appeared pretty useful... and indestructible. He threw his shield, which cut off one guardian's head, while Captain got to the other man, punching him straight in the face with such strength that the girl wasn't sure if this man will ever recover. The other guard kept shooting but somehow, Captain man managed to miss every bullet.
Someone should give these idiots a Stormtrooper outfit... - she thought.
Once the guards had no more bullets in their guns, they hesitated if fighting Steve Rogers made sense. Captain used their moment of hesitation and punched the warden, who hit the wall on the other side of the lab, she could hear man's bones breaking. The last guard tried to flee but he didn't manage to get to the corridor. Steve's shield worked miracles. One metallic clang and it was quiet again.

All that was a new thing to her. She has never seen anyone but the guards with guns and rifles or the scientists that performed experiments on her and at that point, she felt confused. In fact, she hated the people who kept her in here but what about the shield-guy? Is he going to kill her too? Well, that would be a relief.

Captain America was breathing hard as he looked around the room. It was very dark and big, yet almost empty laboratory. A few tables, papers and colorful vials were lying in mess by the concrete walls. Shelves, now overturned. Few lamps, barely illuminating the inside. One, big, metal door. No windows. And a cell. In fact, a simple platform, but Steve knew it was surrounded with a force field. Inside there stood a girl. Well, so he assumed, because the thing in the cell didn't look like a human at all. With her black, tangled locks, ashen skin and ripped white dress she looked more like a ghost or a demon.

-Nat, you might wanna see that. Tell everyone to gather up in the lab 7-02 - he said to the ear-piece.

-Be there in a second - a female voice answered.

The girl in a cage still didn't move. She looked straight into Steve's eyes, trying to find out what his intentions are. Her face was emotionless, like a statue. But what he saw in her eyes terrified him. It was a mix of the worst and most painful emotions - fear, terror, misery and anger. But still, she stood there, without a twitch, and looking at him.

-Hello there - Steve steeped closer and lifted a fold of papers from the ground.

Experiment 066 - "Raven".

-So, you're Raven...?

No answer.

-That's ok. I won't hurt you unless you attack me.

She still didn't say anything but in this silence she heard a sound of footsteps on the corridor. Soon after a red-haired woman and a man in a blue-red-silver robot suit came into the lab. She knew them all. Baron von Strucker took care of that she knew all of the people she will once kill. Or rather be made to kill.

-Oh... Oh my God. Who is that? - asked Rhodes.

-No way... - a gasp slipped Black Widow's mouth.

-I think Pietro and Wanda weren't the only... experiments that survived. - Cap said looking through the files.

-Did she say anything? - Rhodey stepped forward and took a deep look at the girl.

-No. And I don't think she will. But we can't leave her here. I need Wanda, were is she?

-She and Pietro are checking the lower levels, they will be here in a minute.

-Less than a minute. - implied a voice. The girl didn't see him before. All she could notice is a blurred shape running into a room and stopping right in the place, where now stood a quite attractive, young man with silver hair and blue suit. That scared the shit out of her. That wasn't normal, none of it. A single thought passed her mind, but it was really hard to believe. Was that possible that she want't the only mutant? That there were others victims?

How many people did they stuffed with potions and experimented on?! How many of them were changed by this scepter?! - she screamed inside.

-What is it..? - new arrival was really taken aback.

-She is a mutant, at least that's what these files show - Natasha interjected - We don't yet know what did HYDRA do to her, she won't talk.

-Let me handle this. I'm quite good at mind stuff. - said another woman, with a strong Russian accent, entering the room.

Cool. That's great, invite more of your friends to stare at me like I was some kind of exhibit.

-Be careful, Wanda - Rhodey warned.

Woman approached to the cell. The girl inside stepped backwards as she saw a red fire in Wanda's eyes. Than she felt something... inside her head. It felt like there was somebody searching through her memories, digging in her brain. Almost as if her mind was a huge book and Wanda was this anxious librarian, desperately looking for an answer. Than, all of her memories started to fly before her eyes. It hurt.

-Stop it! - she shouted and fall to her knees, hiding her face in her hands. Wanda stepped away immediately with a concerned look at her face.

-What's wrong? - silver haired man approached Wanda and grabbed her shoulder.

-I... I don't know. She felt me searching through her thoughts. It never happened before. I have no idea what's going on.

-Did you see something? - asked Steve in a demanding voice.

-Not much. It seems like her memories were wiped out a few months ago. All I could see is this lab. She doesn't remember anything else. She's afraid, we need to get her out of here.

Hearing it, Natasha caught a glimpse of Steve's wry face.

-We don't know what she might be capable of. Wanda, can you put her into coma? - Cap quickly asked.

-You want to take her to the S.H.I.E.L.D. quarters? Are you sure?

-She's not a monster. This girl needs help, and we are the only ones that can give it to her. Besides, you think leaving her to die in this rotted cell is a better idea? - Cap inquired whilst all the rest stood in silence or searched through the lab.

-Well... No actually. - Wanda turned again towards the cage.

The girl inside was looking at her with tears in her eyes. Never had she been so scared. Before she could even think about doing something, stopping them, she felt something hitting her head. Before she blacked out she realized it was the floor.
