@Chumleeofborg86, Thanks, but it is not enough. Kung Fu can be his first fighting style, but I am pretty sure that Desmond knows more Fighting Styles than just Kung Fu.

Besides, Please send Me a link from YouTube with the Scene where Desmond tells Animus that He knows Kung Fu.

Guys, I suggest You to talk with Godzillarex, from YouTube.

Maybe He can Help Us.

@RIGBY77 It's a reference to Matrix.

But Desmond must known through bleeding effect swordmanship (Altaïr, Ezio, Connor), Boxing (Ezio and Connor), markmanship (Ezio and Connor), surely regional fighting technics from his ancestors. He also had a training in fencing and close combat if I remember.

@Francesco75 Your answers are very good, but still, I want better answers.

Also You did some Mistakes:

Markmanship = Combat/Action Shooting

Swordmanship = Fencing

Besides, You did One Thing Right:

You said Boxing.

Furthemore, You are Right.

That scene really is a reference to Matrix.

Shooting and Fencing are Fighting Styles (maybe you specifically meant unarmed combat?) and that's the best answer you are going to get because that's as specific the franchise gets about Desmond's capabilities in this regard.

But maybe you should talk to Godzillarex instead.

Himself Connor Kenway Altair Ibn La Ahad and Ezio Auiditore fighting styles

The best you are gonna get from what we have seen desmond use is

Boxing

Street fighting

MMA

Wrestling

Knife fighting

You talk like an AI

You always know a working joe

Ostensibly as the Reader he knows all of them.

MOR JUNK.
