Black anime characters

I've personally never seen a black anime character.  Do they exist?

Calling Mr. Popo black is offensive to black people (which I am), and now I'll tell you why.

You know in America, the "blackface" days, where black people painted their faces black with red lipstick and danced around on stage? Just so all you non-black people know, that was NOT a good time in American history for black people, it was degrading, it was shameful, it was black people forcing themselves to make a mockery of...themselves! Because they had no other way to get what the white people had, to be entertainers, to have money.

Mr. Popo looks like a blackfaced entertainer. Japanese people don't know black people, they only know what's on TV about them, and therefore a whole bunch of rude and disrespectful stereotypes are displayed in cartoons such as DBZ.

MR. POPO IS NOT FUCKING BLACK.

(I heart Boondocks.)
