Alexander the great?
Hmm, I'll go with this
Will Smith - Men in black (HQ) - YouTube
for two reasons.
Firstly, Alexander means defender of men/mankind. Makes sense.
Secondly Alexander was renowned for his attempts to promote multiculturalism within his empire in an effort to do away with the ancient Greek/Persian-Barbarian distinctions and fully integrate the various peoples under his sway.
As such, he would totally dig the raw hip hop subculture that Will Smith epitomises.
Peace out.
