Pokemon Black and White tends to disprove that race stereotype and is one of the first games to feature black trainers (One's a gym leader, another's an Elite Four member!). There's also Caucasian trainers --- Just look at Barry from Pokemon Diamond/Pearl (The chicken rival with the blonde hair xD). Either that or Japanese kids these days are really interested in dying their hair various colors to go with the flow.
Anyway, I'm going to move this to Resources, and I'm sure some people would gladly appreciate your trainer spriting skills.
News/Suggestions/Feedback doesn't seem to really fit with this topic, unless a Pokemon theme was running concurrently or something, I don't know. xD
