Quintessence: A unique form of energy, specifically life itself. Katrina Hart, young SHIELD agent and mutant. Having been raised by some of SHIELD's best agents and a man with a Captain America trading card collection, her name was one of the top choices for the Avengers Initiative. When a threat from an entirely different world came into the picture, the teen was on the front lines of it all, and she quickly realized she was in over her head. So, along with 6 of Earth's mightiest heroes, she was thrown headfirst into the deep end, and the world was resting on her shoulders. And she was determined to keep it above the surface, whether or not she drowned. (Sorry if this description sucks, it's my first story, so please be gentle. Haha! Constructive criticism is welcome, but again, nothing too harsh, please. Also, I only own Katrina and her storyline, everything else belongs to Marvel. Anyways, I hope you like the story! Will be trying to update weekly.)

Running since the age of 8. It's been 6 years since then, 6 long years... She's been hacking from the moment she escaped HYDRA. She won't stop until HYDRA is done. Done with their schemes and plots. Done with their tricks and weapons. Done with torturing, torturing people like they tortured her. She's no normal girl. She had been what HYDRA hoped to be their strongest weapon. Because she was a little part of all the avengers, crammed into the body of a 14 year old girl. What made her HYDRA's ex strongest weapon? It was that she had been injected with the blood of ALL the Avengers...what could go wrong? It all changed the day she hacked into the computer system of non other, than Tony Stark. You may ask what this girls name is...it's Subject 37-D2 I DO NOT OWN AVENGERS/MARVEL! I ONLY OWN CHARACTER 37-D2.

What, never heard of her? Typical. She has more kills than the Winter Solider. She was taken when she was 4 for her powers. When she escaped she decided to keep her name. HYDRA thinks she is dead. They aren't looking for her. When Clint crashes the quinjet in the field beside her yard, she allows them to stay in her house, no one recognizes her. No one, until Winter walks through the door, and sees a girl that he valued like a sister come up the stairs to greet him and his new team. (This is set in a time and place where the Sokovia accords don't exist and Tony understood that Winter was not to blame for his parents death)

Mistreated from a young age and sent away in her teens by her parents, she all but disappeared off the face of the Earth. Years of abuse from her new 'guardians' almost drove her mad- until at 22 she was taken by Hydra and spent the next year the subject of inhumane experiments, causing her to release her powers. She made her escape, and the Avengers discovered her collapsed in the snow after the Hydra base exploded. The team were faced with a difficult choice to make in order to save her life. Will she be able to open up and start again? Will she be able to accept her reality? And where will her choices take her? * Don't judge the cover I don't have Photoshop I had to use Microsoft Paint haha my laptop is so old. Also this is the first time I am sharing one of my stories so if you judge please be gentle! * It doesn't really follow the movies, it is more of an in-between movies kind of thing crossed with my own storyline. I do not own Marvel or any of their characters.

Sent to retrieve the elusive Power Stone, she makes contact with it-and it unlocks unimaginable powers within her, powers even greater than those of the Scarlet Witch. These new abilities beginsparking questions and memories she'd long suppressed. As Y/N grapples with her newfound powers and a growing sense of self, she crosses paths with Peter Parker, a young hero with a heart as brave as his web-slinging skills. Drawn to each other, Y/N finds in Peter a connection unlike any she's ever known, one that helps her begin to unravel her past and find her true identity. Disclaimer: I don't own any characters, marvel owns them only the storyline is mine.
