Ultron: You think you're saving anyone? I turn that key and drop this rock a little early and it's still billions dead. Even you can't stop that.
Thor: I am Thor, son of Odin, and long as there is life in my breast...I am running out of things to say. Are you ready?
[Vision sucker punches Ultron with Thor's hammer.]
Vision: It's terribly well-balanced.
Thor: Well, if there's too much weight, you lose power on the swing.
Natasha Romanoff: Thor, report on the Hulk.
Thor: The gates of Hel are filled with the screams of his victims!
[Natasha glares at him while Bruce groans and puts his head in his hands.] Thor: But not the screams of the dead, of course. No, no... Wounded screams... Mainly whimpering, a great deal of complaining and tales of sprained deltoids and...gout.
Thor: There are six stones out there. Thanos already has the Power Stone because he stole it last week when he decimated Xandar. He stole the Space Stone from me when he destroyed my ship and slaughtered half my people. The Time and Mind Stones are safe on Earth, they're with the Avengers.
Peter Quill: The Avengers?
Thor: The Earth's mightiest heroes.
Mantis: Like Kevin Bacon?
Thor: He may be on the team, I don't know.
Eitri: You're about to take the full power of a star. It will kill you.
Thor: Only if I die.
Eitri: That's what...killing you means.
Thor: You know, I'm 1500 years old. I've killed twice as many enemies as that. And every one of them would have rather killed me than not succeeded. I'm only alive because fate wants me alive. Thanos is just the latest of a long line of bastards, and he'll be the latest to feel my vengeance - fate wills it so.
Sadak: Some times I wake up in the morning and I don't even know who I am. Where I am. In what country. And you know me?
Nicholas Hathaway: I know you, and you're about money, because it's your scoreboard in the virtual world.
Chen Lien: I'm sorry for what happened to you.
Nicholas Hathaway: Well, don't be. I'm not fishing for sympathy, here. I did the crime, I'm doing the time. Time isn't doing me.
Chen Lien: What's that mean?
Nicholas Hathaway: I do my own time, not the institution's. See, to hold on to who you are in there, you dedicate yourself to your program. You work out on your body and your mind.
