Mental powers, huh? Well, that rules Khan out.
Not in the least, because Cumberbatch elaborates to indicate that he's not talking about literal "powers" like mind control or telekinesis. Khan in "Space Seed" was clearly as accustomed to leading by persuasion and/or seduction of one kind or another as by intimidation or force.
In fact, Cumberbatch's description of the villain leaves some version of Khan as a possibility and rules Mitchell out.
