4. Admiral Marcus - Star Trek Into Darkness
It's just too obvious to label Khan as the prick of Star Trek Into Darkness, especially when a far more devious, insidious character is playing puppet-master behind the scenes. Yes, I'm talking about Admiral Marcus (Peter Weller), who Khan reveals woke him from 300 years of suspended animation and essentially held his crew of 72 personnel hostage, in order for Khan to help him design advanced weaponry to take on the Klingons. Though in some way Marcus' plan might have been well-intentioned, that all goes out the window when he decides to fire upon the Enterprise from his ship, the USS Vengeance, knowing that it will likely kick-start a war with the Klingons. He's the worst kind of douchebag, given that he's a bureaucrat who cannot see the human element, and so when Khan eventually kills him, we're nothing short of absolutely delighted.
