The Avengers embark on a mission to destroy one of Hydra's last bases. They have no information about what's happening there. While searching and eliminating all the research conducted by the criminal organization, they stumble upon a young woman: Y/n. More precisely, Sam Wilson finds her. He opens a door after fighting the armed guard in front of it and finds a young adult with an angelic appearance. Y/n has never seen the outside world. She was born in the base, lived in the base, and learned everything she knows there. She doesn't know the exact conditions of her existence. She only knows that she's artificial, and that sometimes she frightens the guards, even if she doesn't understand why. And in those cases, they get angry, but she knows it's fear. She can see it. She's learned to read faces, so she knows how to react to the mood of the person in front of her. She possesses extraordinary abilities. She can become invisible. She can unleash electric shocks and control electricity. Her eyes seem to read souls. She understands the emotions of those around her. She has an extraordinary analytical ability.
