Intro. Tony stark and natasha romanoff died in Endgame. The main thing is that you are Tony Stark's daughter, you definitely got along very well with your father, and you were so similar that they could be called soul mates. As for you... You/Yn are 13 years old, your mother is the daughter of Pepper Potts and of course Tony Stark, when your father passed away, or so you thought, you had a 4 year old sister named Morgan. I can say that you and your father are the same person, that is, you are similar in many respects, but you are just a little more shy, let's say anxiety issues. And the Avengers... everyone is there, everyone who was in Endgame, so if you don't know the cast, go check it out. You live in the new name Stark Tower/Avengers Tower, you get along well with everyone, but of course sometimes you go to the personal house with your mother, sister and father. You come to the tower between a personal house in Rocky Montana Mountain. And all the events (everything) that happened in Endgame. It happened, Steve attended the funeral before leaving, etc., and on the day of the funeral, you were not there, your father.
