Top 50 Star Trek Characters – #13 Khan
For those who only knew “Khaaaaaaaaan!” as the villain in Star Trek II, he did indeed appear in an Original Series episode entitled “Space Seed”.
A product of genetic engineering, he and other “superhumans” like him attempted to take control of Earth until they were defeated forcing the survivors to flee into space via sleeper ship. Khan was both a physical and mental specimen, and proved to be a tremendous adversary to Captain Kirk. He is one of the most popular villains in all of Star Trek lore.
