Dude, people do have afros, what the hell is wrong with that? And clearly he can fight and kick some ass, judging by the other screenshots.
I mean, seriously, if a black guy isn't a bishounen he's a stereotype? And Nomura is probably the last designer who'd pull stupid shit like that. He knows how to design a dark skinned character without making them look like something out of Amos and Andy.
The guy just looks like a friendly black guy with an afro and a baby chocobo. I'm more refreshed about him being different. I can see the Richard Pryor/Disco connection but honestly that's not stereotypical, that's just funny.
There's only a stereotype if you look for one and try to put him in one.
