Here's a suggestion from Star Trek Into Darkness, written by Roberto Orci & Alex Kurtzman & Damon Lindelof, directed by J.J. Abrams. Khan: Your crew for my crew. Spock: You betrayed us. Khan: Oh, you are smart, Mr. Spock. James T. Kirk: Spock, don't... [Khan knocks him down] Khan: Mr. Spock, give me my crew. Spock: What will you do when you get them? Khan: Continue the work we were doing before we were banished. Spock: Which as I understand it involves the mass-genocide of any being you find to be less than superior. Khan: Shall I destroy you, Mr. Spock? Or will you give me what I want? Spock: We have no transporter capabilities. Khan: Fortunately, mine are perfectly functioning. Drop your shields. Spock: If I do so I have no guarantee that you will not destroy the Enterprise. Khan: Well, let's play this out logically then, Mr. Spock. Firstly, I will kill your captain to demonstrate my resolve, then if yours holds I will have no choice but to kill you and your entire crew. Spock: If you destroy our ship, you will also destroy your own people. Khan: Your crew requires oxygen to survive, mine does not. I will target your life support systems located behind the aft nacelle. And after every single person aboard your ship suffocates, I will walk over your cold corpses to recover my people. Now, shall we begin? Khan is an interesting nemesis here because he's beating everyone at their own game: he's already overpowered Kirk, the man of action, and here he (apparently) outwits Spock. As with any good nemesis, he presents the perfect threat and the perfect challenge to the protagonists.
