In the comic books, Colleen Wing is a descendent of a family of Samurai who avenged her grandfather's death with the help of Iron Fist. In the latest promo, we get to see her take down two thugs.

One of the big draws to the NETFLIX series IRON FIST will be the martial arts action. Fight choreography will be essential to it's success and even though there's no shortage of inspiration to draw from, many times fight sequences fall flat. That's not the case in the latest promotional video released for the upcoming series.

Without any context, it's difficult to understand why Colleen Wing (Jessica Henwick) is submitting herself to fight in a cage. Nevertheless, she handles herself with grace and a killer instinct against two stereotypical, muscled-up bullies. The fight sequence is well choreographed as she not only delivers some clean shots but also takes a few. It's not enough to stop her as she uses a Brazilian Jiu-Jitsu technique known as "omoplata" to lock down a shoulder until it breaks.

There's no story, but plenty of style in this minute and a half clip of the highly lethal Colleen Wing!
