The Guide to Being an Avenger

Y/N was taken by Hydra in the 1940's and turned into an unsuspecting young assassin named The Ghost. Decades later, after Hydra is defeated, she is found by Bucky Barnes and the Avengers, and taken care of.

(The plot of the movies has been changed cause I don't want all of them to die so I just remade it. mostly very silly goofy.)
