Thanos
- Thanos: Daughter.
- Young Gamora: Did you do it?
- Thanos: Yes.
- Young Gamora: What did it cost?
- Thanos: ...Everything.
- Gamora: I was a child when you took me.
- Thanos: I saved you.
- Gamora: No. We were happy on my home planet.
- Thanos: You were going to bed hungry, scrounging for scraps. Your planet was on the brink of collapse. I'm the one who stopped that. You know what's happened since then? The children born have known nothing but full bellies and clear skies. It's a paradise.
- Gamora: Because you murdered half the planet.
- Thanos: A small price to pay for salvation.
- Gamora: You're insane.
- Thanos: Little one, it's a simple calculus. This universe is finite, its resources, finite. If life is left unchecked, life will cease to exist. It needs correcting.
- Gamora: You don't know that!
- Thanos: I'm the only one who knows that. At least, I'm the only one with the will to act on it.
- Thanos: I know what it's like to lose. To feel so desperately that you're right, yet to fail nonetheless. It's frightening, turns the legs to jelly. I ask you to what end? Dread it. Run from it. Destiny arrives all the same. And now it's here. Or should I say, I am.
- Peter Parker: [while teleporting and beating up Thanos] Magic. More Magic. Magic with a Kick. Mag...
- [Thanos graps Peter by the throat]
- Thanos: Insect!
- [Thanos has Gamora]
- Peter Quill: You let her go!
- Thanos: Ah, the boyfriend.
- Peter Quill: I'd like to think of myself more as a titan-killing, long-term booty call.
- [from trailer]
- Thanos: In time, you will know what it's like to lose. To feel so desperately that you're right. Yet to fail all the same. Dread it. Run from it. Destiny still arrives.
- Thanos: You have my respect, Stark. When I'm done, half of humanity will still be alive. I hope they remember you.
- Stonekeeper: What you seek lies in front of you. As does what you fear.
- Thanos: [on the edge of a cliff] What's this?
- Stonekeeper: The price. The Soul Stone holds a special place among the Infinity Stones. You might say, it is a certain wisdom.
- Thanos: Tell me what it needs.
- Stonekeeper: To ensure that whoever possesses it understands its power, the stone demands a sacrifice.
- Thanos: Of what?
- Stonekeeper: In order to take the stone, you must lose that which you love. A soul for a soul.
- Thanos: Titan was like most planets. Too many mouths, not enough to go around. And when we faced extinction, I offered a solution.
- Dr. Stephen Strange: Genocide.
- Thanos: At random. Dispassionate, fair to rich and poor alike. They called me a mad man. And what I predicted came to pass.
- Dr. Stephen Strange: Congratulations, you're a prophet.
- Thanos: I'm a survivor.
- Dr. Stephen Strange: Who wants to murder trillions!
- Thanos: With all the six stones, I could simply snap my fingers, and they would all cease to exist. I call that... mercy.
- Dr. Stephen Strange: And then what?
- Thanos: I finally rest, and watch the sunrise on an grateful universe. The hardest choices require the strongest wills.
- Dr. Stephen Strange: I think you'll find our will equal to yours.
- Thanos: Our?
- [the Avengers appear]
- Thanos: Stark.
- Tony Stark: You know me?
- Thanos: I do. You're not the only cursed with knowledge.
- Tony Stark: My only curse is you.
- Ebony Maw: Hear me and rejoice. You have had the privilege of being saved by the great Thanos. You may think this is suffering, no. It is salvation. The universal scale tips toward balance because of your sacrifice. Smile. For even in death, you have become children of Thanos.
- Thanos: I know what it's like to lose. To feel so desperately that you're right, yet to fail none the less.
- [Picks Thor off the ground]
- Thanos: Frightening. Turns the legs to jelly. I ask you to what end? Dread it? Run from it? Destiny arrives all the same, and now it's here. Or should I say: I am.
- Thor: You talk too much.
- Thanos: [to Loki while holding Thor by the head] The Tesseract. Or your brother's head. I assume you have a preference.
- Loki: Oh, I do. Kill away.
- Thor: [Shrieks in pain as Thanos presses the Power stone against his head]
- Loki: All right, stop!
- Thor: We don't have the Tesseract. It was destroyed on Asgard.
- Loki: [Presents the Tesseract to Thanos]
- Thor: You really are the worst, brother.
- Loki: I assure you, brother... the sun will shine on us again.
- Thanos: Your optimism is misplaced, Asgardian.
- Loki: Well, for one thing, I'm not Asgardian. And for another... we have a Hulk.
- Ebony Maw: [while Hulk beats up Thanos] Let him have his fun.
- Thanos: [Heimdall sends Hulk to Earth by summoning the bifrost] That was a mistake
- Thor: [Thanos stabs Heimdall in the chest] No! You're going to die for that.
- Ebony Maw: [Presenting the Tesseract to Thanos] My humble personage bows before your grandeur. No other being has ever the might, nay the nobility, to wield not one, but two Infinity Stones. The universe, lies within your grasp.
- Thanos: There are two more stones on Earth. Find them my children, bring them to me on Titan.
- Proxima Midnight: Father, we will not fail you.
- Loki: If I might interject. If you're going to Earth, you might want a guide. I do have a bit of experience in that area.
- Thanos: If you consider failure experience.
- Loki: I consider experience experience. Almighty Thanos... I, Loki, prince of Asgard... Odinson... the rightful king of the Jotunheim... god of mischief... do hereby pledge to you... my undying fidelity.
- Thanos: [Uses the Gauntlet to stop Loki attempting to stab him in the neck] Undying? You should chose your words more carefully.
- Loki: [as Thanos strangles him to death] You... will never be... a god
- Thanos: No resurrections this time.
- Thanos: How is it you know this place so well?
- Red Skull (Stonekeeper): A lifetime ago, I too sought the stones. I even held one in my hand. But it cast me out, banished me here, guiding others to a treasure I cannot possess.
- Gamora: All my life I dreamed of a day, a moment, when you got what you deserved. And I was always so disappointed. But now you kill and torture and you call it mercy. The universe has judged you. You asked it for a prize and it told you no. You failed. And do you want to know why? Because you love nothing. No one.
- [Thanos sheds a tear]
- Gamora: Really, tears?
- Red Skull (Stonekeeper): They are not for him.
- Gamora: No. This isn't love.
- Thanos: I ignored my destiny once. I cannot do that again. Even for you. I'm sorry, Gamora.
- Gamora: NO!
