Maisie Williams as Arya Stark
Game of Thrones viewers basically watched Maisie Wiilliams grow up on screen. She played Arya Stark, the youngest daughter of Kat and Ned Stark who was just one of the boys. She was the total opposite of her sister, Sansa, and was not a fan of frilly dresses or sewing circles. When Williams grew into herself, people were (weirdly) shocked to see how much she differed from her character.
