Alexander The Great 

Alexander the Great may be one of the greatest political and military geniuses the world has ever known. Equal parts charismatic and downright ruthless, by the age of thirty, he had created the largest army in history, achieving unprecedented military and political power.

Ancient documents consistently report that the Macedonian conqueror had a condition called heterochromia, where the eyes are different color. The handsome rule died at the age of 33 in Babylon, the city he intended to establish as his capital.
