Stereotypes

Beyblade has characters from many different ethnicities. So the poor souls are stuck with stereotypical personalities. Aoki Takao and co. have portrayed the characters - I think - unfairly. For instance the Majestics are all Europeans to it's tantamount for them to be snotty rich kids. The All Stars - though not obese tourists as the British think - are jocks. The Blitzkerig Boys aren't Russian stereotyped at all and nor are the Japanese characters (the reason for that being because Aoki is Japanese himself).
I always thought it bothering that some characters have no obvious ethnicity, however most of these characters are so bland it obvious to the point that they're Japanese.
