Ronan: The Orb is in my possession, as I promised.
Thanos: Bring it to me.
Ronan: Yes, that was our agreement. Bring you the Orb, and you will destroy Xandar for me. However, now that I know it contains an Infinity Stone, I wonder what use I have for you.
Thanos: Boy, I would reconsider your current course.
Korath: Master! You cannot! Thanos is the most powerful being in the universe.
Ronan: Not anymore.
(Tony, Cap and Thor approch Thanos...)
Thanos: You could not live with your own failure. Where did that bring you? Back to me. I thought by eliminating half of life, the other half would thrive. But you've shown me, that's impossible. And as long as there are those that remember what was, there will always be those that are unable to accept what can be. They will resist.
Tony Stark: Yep. We're all kinds of stubborn.
Thanos: I'm thankful. Because now, I know what I must do. I will shred this universe down to its last atom. And then... With the stones you've collected for me, create a new one... Teeming with life that knows not what it has lost, but only what it has been given. A grateful universe.
Steve Rogers: Born out of blood.
Thanos: They'll never know it. Because you won't be alive to tell them.
Thanos: I am inevitable.
(Thor cuts off his head)
Rocket: What? What did you do?
Thor: I went for the head.
Thanos: With all six Stones, I could simply snap my fingers. They would all cease to exist. I call that... mercy.
Stephen Strange: And then what?
Thanos: I finally rest. And watch the sun rise on a grateful universe. The hardest choices require the strongest wills.
Stephen Strange: I think you'll find our will equal to yours.
Thanos: This universe is finite. Its resources, finite. If life is left unchecked, life will cease to exist. It needs correction.
Peter Quill: You let her go!
Thanos: Ah, the boyfriend.
Peter Quill: I like to think of myself more as a Titan-killing long term booty call. Let her go.
Peter Quill: Or I'm gonna blow that nutsack of a chin right off your face!
Loki: Almighty Thanos, I, Loki, Prince of Asgard... Odinson... The rightful king of Jotunheim, God of Mischief... Do hereby pledge to you, my undying fidelity. (Loki tries to stab Thanos)
Thanos: "Undying"? You should choose your words more carefully.
Loki: You... will never be.... a god. (Thanos chokes him and eventually snaps his neck)
Thanos: No resurrections this time.
Loki: If you're going to Earth, you might want a guide. I do have a bit of experience in that arena.
Thanos: If you consider failure experience...
Loki: I consider experience, experience.
Ebony Maw: Hear me... and rejoice. You have had the privilege, of being saved by the Great Titan. You may think this is suffering. No. It is salvation. Universal scales, tipped 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 nonetheless. As lightning 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: Fun isn't something one considers when balancing the universe. (Looking at The Infinity Gauntlet) But this... (laughs) does put a smile on my face.
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.
As the Avengers and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality. Everything the Avengers have fought for has led up to this moment - the fate of Earth and existence itself has never been more uncertain. (IMDb) │ Produced by Marvel
