You know Usutu, the African Precog played by Ntare Guma Mbaho Mwine, who though his ability to paint the future helps set Matt Parkman and now it seems Hiro and Ando in the right direction? He's a total abuse of the mystical stock character known as the "Magical Negro".
The white characters come to him looking for answers, and through his magical ability of precognitive painting (and headphones?) he shows them some special insight and sends them along on their way.
To quote wikipedia:
He has no past; he simply appears one day to help the white protagonist...He is patient and wise, often dispensing various words of wisdom, and is "closer to the earth"...Although from a certain perspective the character may seem to be showing African-Americans in a positive light, he is still ultimately subordinate to European-Americans. He is also regarded as an exception, allowing white America to like individual black people but not black culture.
Well, I guess if it's good enough for Grant Morrison's Batman...
