Even if you've never heard of the Eugenics Wars before (I don't remember Into Darkness going into too much detail), as you've probably guessed from this article alone, any TV series that explored them would not be complete without Kirk's number one nemesis himself, Khan Noonien Singh. Looking back it is hard to believe that Khan has only made three on-screen appearances (Space Seed, The Wrath of Khan, and Into Darkness), and if there's ever any character that needs more screen time, we surely have him here. Throughout those three appearances Khan has been played by two different actors, Ricardo Montalban and Benedict Cumberbatch, each showing us a different aspect of this enigmatic character. Montalban was charming and persuasive, while Cumberbatch was cold and calculating. A Eugenics Wars series would enable us not only to see Khan's lust for power once more, but also what this dominant figure did when he had attained it. Although his previous appearances told stories from fractured historical records, this is far from seeing it with our own two eyes. Since Montalban sadly passed away in 2009, this leaves only one choice for the role...
