Y/n parker is peter parker's older sister. Before he was born she was kidnapped by hydra and passed back and fourth between the Redroom and hydra. Once she escapes she finds a little brother at home. She is having a normal day until she gets a call about her brother getting into a fight at school. She walks out of the small coffee shop only to get trampled by hydra. The avengers just so happen to be in that exact coffee shop. So, she lets the Avengers deal with Hydra. Once she handles the deal with Peter, the Avengers kidnap her and take her to the tower for questioning. Director fury just so happened to be there and recognized her. She is forced to stay in the tower for the three days, to make sure she isn't a threat. While at the tower, she occupies her self by doing things with the Avengers and making weapons. Why the weapons? She's just bored and maybe trying to make sure nothing happens to Peter. No time soon anyways. After the three days, she decided to continue staying at the tower. She chooses to keep her apartment as a safe room when it's needed. Everything is going good with the Avengers until HE comes and destroys it all. HE takes her brother from her, and Tony, and everyone else. Her and Tony were besties when it came to snarky and on the dot jokes about the most absurd things. And clint, they were the best pranksters. But that's all gone now. Then Thanos. She couldn't keep Peter safe enough from HIM or Thanos. She truly lost everything. Or did she.
