The youngest member of Red Regiment's 3rd Black Ops, Xyko is the tech guy of the squad. 

You know the guy in movies that sits in a van with a bunch of computers, looking at cameras and stuff? Add a hint of badassery, and you've got Xyko. More naïve than the other members of the 3rd Black Ops, he still knows how to get the job done.

I realize he doesn't really talk much in this first episode, but much like pretty much every character on this post, we're trying to give him a more prominent role.
