Black anime characters

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

The fact many characters who could be black turn out to be
non-black kinda annoys me.
The Gunsmith Cats girl is Indian, Nadia is actually an Alien(?),
Mihoshi is also an Alien, Pluto is South Asian(?)..
While I don't think Japanese people harbor strong prejudice against black people, blacks are sortof underrepresented, I think.
