Natasha Romanoff / Black Widow - Scarlett Johansson - Avengers: Age of Ultron 2015 This is my favorite super hero
"Am I the only one who noticed Scarlett Johansson was a man for half a second? That's Heidi Moneymaker's arms. She really is that muscular. It's called "stunt woman".
Black Widow - Iron Man The Avengers, and upcoming movie Captain America (Not a fan of the straight hair.) I love her hair in iron man 2
