Nobody cares about if he was a black guy with a gun, he was freaking sweet with his array of weapons. Sometimes having stereotypical stuff is better than not. I mean, can you imagine if he had some silly mallet or he had a sword or something? I mean, Lightning had a gun too.
He wasn't the only one, I could imagine him with a spear though, but nothing else.
If FFXIII was a movie... we all know Sazh would be the first to die. He'd go out guns-a-blazin on that train before it crashed and created a massive explosion. Lightning would probably mention him once or twice after that due to guilt, but nobody would ACTUALLY care. That little chocobo might trigger a few tears though.
