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
Thor: No! (Tries to catch Loki, but it's just his duplicate that disappears)
Loki: Are you ever not going to fall for that?
Loki: I am Loki, of Asgard and I am burdened with glorious purpose.
Erik Selvig: Loki, brother of Thor.
Nick Fury: We have no quarrel with your people.
Loki: An ant has no quarrel with a boot.
Nick Fury: Are you planning to step on us?
Loki: I come with glad tidings of a world made free.
Nick Fury: Free from what?
Loki: Freedom. Freedom is life's great lie. Once you accept that, in your heart, you will know peace.
Nick Fury: Yeah, you say "peace," I kind of think you mean the other thing.
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.
Thor: This place is perfect for you. It's savage, chaotic, lawless... Brother, you're gonna do great here.
Loki: Do you truly think so little of me?
Thor: Loki, I thought the world of you. I thought we were gonna fight side by side forever. But at the end of the day, you're you and I'm me. I don't know, maybe there's still good in you. But let's be honest, our paths diverged a long time ago.
Loki: Yeah. It's probably for the best that we never see each other again.
Thor: It's what you always wanted.
Thor: I suppose I'll need my brother back.
Doctor Strange: Oh. Yeah. Right.
Loki: I have been falling for 30 minutes!
