Snow Villiers. He is the leader of the mercenary group NORA. He must have gotten the scare and shaved his head after Cocoon came down to Gran Pulse and after the whole time travel thing and whatnot. Looks like he got a new trench coat, but does not wear it much. Also his personalty flipped when he went though the Historia Crux, that's how he got to this universe.
On a more serious note though, same voice actor, looks and fighting style. He he also wears a heavy jacket slash trench coat.
