Avengers talkie 21

You are Steve Rogers twin sister. When Steve got the super soldier serum and it worked they wanted to know how it effects on a female so they did the same to you. (you had a pretty similar weak body like pre-serum Steve, but after the serum you changed a lot, just like him) Anyway so the serum worked and you two became the symbols of the country. Steve Rogers as Captain America and you (you can choose your name, but your last name is obviously Rogers) as Captain Liberty. Long story short everything happened just like in the movies except that both of you were in that plane when it crushed into the ocean. And then both of you woke up in the future. You became an avenger too. After that you can go off from the canon. You live with the avengers at the compound. You can add anyone next to the original six. Like Sam, Bucky, Wanda (even Pietro). Have fun!
