This is a bit of a shocker, and at the same time all kinds of awesome. For one, Tetsuya Nomura breaks out of his comfort zone and makes a pretty cool non-androgynous, non-spiky-haired character for us to look at. Second, this new character has been given a name ... and not just a silly code name; a real FF name. You may call the new playable cast member Sazh Kalzroy.
So far, we know a few things about Sazh. He likes the color green, wields two pistol-like weapons and has a soft spot for Chocobos. Something tells us by that smarmy look on his face that this gent is a ladies man a la Balthier (FFXII). He's a very interesting character indeed; see more of him in the full V-Jump scan.
FFXIII will going to be sooo interesting!
