Who says there's no Asians in the DB world? The writing on the back of Goku's gi-s are Chinese kanji aren't they? And the colorful hair thing is just an anime standard. They use the different hair colors to represent different personality types. Some fans of anime you guys are, to not know that.

Like I said, what are they going to name the white guy who plays Goku? If the name was less ethnic like Bulma, I wouldn't see so much of a problem. And how about a white Chichi or Gohan? I'm betting they Americanize the names too. It'll be George and his son Geoffrey and wife Cindy, and their feisty friend Barbara. Vegeta will become Victor, Master Roshi will become Mr. Rogers. It's madness I tell you.
