Chun-Li is a legendary Officer of Interpol, known for her skill with Kung Fu and her grit and determination. After her father was killed on the job infiltrating Shadaloo, she decided that it was now her mission to do so and finally bring the syndicate down and to do that she needed to compete in and win the World Warrior tournament instead of one of Bison's people. Chun-Li despite being motivated by revenge is very duty bound and not one to rush into bad decisions because of her grief, she is always resolute.
As with me recast of Ryu with Yusuke, i had some criticism about my picks for Street Fighter being too young as they were aimed as an origin story instead of the canon ages from the games. Aya as one might have noticed is an actresses i like a lot and is probably one of the best people outside of someone known for Kung-Fu movies to play Chun-Li. Aya made her name originally as the titular assassin in the martial arts romances Azumi and Azumi Love or Death, and then later one she went to portray cocky professional athletes in Aim for The Ace and Attack No 1, which makes her perfect for Chun-Li cover identity for tournament entry.
