The Avengers team. Steve, bucky, Tony, Natasha, Bruce, Wanda, Peter, fury, Maria, Thor, Loki, Sam and.... Y/N... Who's heard of childish because of bad past? Yep, that's Y/N Y/L/N. Her past is bad... Abusive family, ten years at hydra and suicidal.

The team has never known Y/N's past, they all just got used to her childish behavior. Bucky is Y/N's boyfriend. Y/N is a black magic witch, she can also see ghosts and talk to shadows. She is never really serious, not even during missions.
