Khan
- Khan: [quoting from Melville's Moby Dick] To the last, I will grapple with thee... from Hell's heart, I stab at thee! For hate's sake, I spit my last breath at thee!
- Kirk: Khan, you bloodsucker! You're going to have to do your own dirty work now! Do you hear me? Do you?
- Khan: Kirk? Kirk, you're still alive, my old friend?
- Kirk: Still, "old friend"! You've managed to kill just about everyone else, but like a poor marksman, you keep missing the target.
- Khan: Perhaps I no longer need to try, Admiral.
- [Khan activates the transporter, and the Genesis device begins to dematerialize]
- Carol Marcus: Oh no!
- David Marcus: Let go! He can't take it!
- [Saavik restrains David and Carol as the Genesis beams away]
- Kirk: Khan... Khan, you've got Genesis, but you don't have me. You were going to kill me, Khan. You're going to have to come down here. You're going to have to come down here!
- Khan: I've done far worse than kill you. I've hurt you. And I wish to go on hurting you. I shall leave you as you left me, as you left her: marooned for all eternity in the center of a dead planet. Buried alive... buried alive...
- Kirk: [enraged] KHAAANNNN!
- [echo]
- Kirk: KHAAANNNN!
- Joachim: We're all with you, sir. But, consider this. We are free. We have a ship, and the means to go where we will. We have escaped permanent exile on Ceti Alpha V. You have defeated the plans of Admiral Kirk. You do not need to defeat him again.
- Khan: [paraphrase from Melville's Moby Dick] He tasks me. He tasks me and I shall have him! I'll chase him 'round the moons of Nibia and 'round the Antares Maelstrom and 'round perdition's flames before I give him up!
- Khan: Captain, Captain, Captain... save your strength. These people have sworn to live and die at my command two hundred years before you were born. Do you mean he never told you the tale? To amuse your Captain, no? Never told you how the Enterprise picked up the Botany Bay, lost in space from the year 1996 with myself and the ship's company in cryogenic freeze?
- Capt. Terrell: I've never even met Admiral Kirk.
- Khan: 'Admiral?' 'Admiral!' 'Admiral'... Never told you how 'Admiral' Kirk sent seventy of us into exile in this barren sandheap with only the contents of these cargo bays to sustain us?
- Chekov: You lie! On Ceti Alpha Five there was life! A fair chance...
- Khan: [shouts] THIS IS CETI ALPHA FIVE! Ceti Alpha Six exploded six months after we were left here. The shock shifted the orbit of this planet and everything was laid waste. 'Admiral' Kirk never bothered to check on our progress. It was only the fact of my genetically-engineered intellect that allowed us to survive. On Earth, 200 years ago, I was a prince with power over millions.
- Chekov: Captain Kirk was your host. You repaid his hospitality by trying to steal his ship and murder him!
- [Khan discovers the Enterprise and realizes it isn't as badly damaged as he thought]
- Khan: There she is! There she is! Ah... not so wounded as we were led to believe. So much the better!
- Joachim: [Enterprise is running with shields down] They still haven't raised their shields.
- Khan: Raise ours.
- [Joachim raises shields]
- Spock: Their shields are going up.
- Khan: Lock phasers on target.
- Joachim: [looks at targeting computer] Locking phasers on target.
- Spock: They're locking phasers.
- Kirk: Raise shields!
- Khan: Fire!
- [Joachim fires phasers]
- Khan: Surely, I have made my meaning plain. I mean to avenge myself upon you, Admiral. I deprived your ship of power, and when I swing around, I mean to deprive you of your life.
- Captain Terrell: Sir, I demand...
- Khan: You are in a position to demand *nothing*. I, on the other hand, am in a position to *grant* nothing.
- [Khan, about to put Ceti Eels in Terrell and Chekov's ears]
- Khan: You see, their young enter through the ears and wrap themselves around the cerebral cortex. This has the effect of rendering the victim extremely susceptible to suggestion. Later, as they grow, follows madness and death.
- Chekov: Khan, listen to me...
- Khan: These are pets, of course. Not quite domesticated.
- Khan: You didn't expect to find me. You thought this was Ceti Alpha VI. Ahh. Why are you here?
- [as Chekov remains silent, Khan picks him up by a handle on the front of his spacesuit]
- Khan: Why?
- [putting him down]
- Khan: Allow me to introduce you to Ceti Alpha V's only remaining indigenous life form.
- [picking up a pair of pincers, he sticks it into a cage; hissing, an insect-like create bites at it]
- Khan: What do you think? It killed 20 of my people, including my beloved wife.
- [holding it down, he carefully picks two smaller insects out of its back]
- Khan: Oh, not all at once. And not instantly, to be sure.
- Chekov: Khan.
- Khan: [to Captain Terrell] I don't know you.
- [turning to Chekov]
- Khan: But you... I never forget a face. Mr... Chekov. Isn't it? I never thought to see your face again.
- Capt. Terrell: Chekov, who is this man?
- Chekov: A criminal, Captain. A product of late 20th-century genetic engineering.
- Khan: [inserting Ceti eels into Chekov and Terrell's ears] Now, tell me, why are you here? And tell me where I may find James Kirk.
- Carol Marcus: This is completely improper, Commander Chekov. I have no intention of allowing Reliant or any other unauthorized personnel access to our work or materials.
- Chekov: I'm sorry that you feel that way, Doctor. Admiral Kirk's orders are confirmed. Please prepare to deliver Genesis to us upon our arrival. Reliant out.
- Khan: Well done, Commander.
- Chekov: You realize, sir, they will attempt to contact Admiral Kirk and confirm the order.
