Drax the Destroyer: This vermin speaks of affairs he knows nothing about!
Rocket Raccoon: [scans an Xandarian citizen] Can you believe they call us criminals when he's assaulting us with that haircut?
Groot: I am Groot! Rocket Raccoon: I know they're the only friends we've ever had!
Drax the Destroyer: I recognize this animal. We'd roast them over a flame pit as children. Their flesh was quite delicious. Rocket Raccoon: Not helping!
Nebula: After Xandar, you're going to kill my father? Ronan: You dare to oppose me? Nebula: You see what he has turned me into? You kill him and I will help you destroy a thousand planets.
Drax the Destroyer: He has no respect!
Ronan: With all due respect, Thanos, your daughter made this mess, and yet you summon ME? The Other: I would lower my voice, Accuser! Ronan: First, she lost a battle to some primitive... The Other: Thanos had put Gamora under your charge! Ronan: ...t...
Gamora: We'll follow your lead.
[in the Broker's shop] Yondu Udonta: [looks at toy dolls] Do you got any other cute little buggers like this one? I like to stick 'em all in a row on my control console.
Gamora: This was my opportunity to get away from Thanos.
Rocket Raccoon: That is true!
The Collector: These carriers can use the stone to mow down entire civilisations like wheat in a field. Peter Quill: There's a little pee coming out of me right now.
Peter Quill: I saw you out there. I don't know what came over me, but I couldn't let you die. I found something inside of myself, something incredibly heroic. I mean, not to brag, but objectively... Gamora: [sigh] Where's the orb?
Rocket Raccoon: Let's get something clear! This one here is our booty. You wanna get to him, you go through us... or, more accurately, we go through you!
The Collector: Carina, get away from that stone! CARINA! Carina: I will no longer be your slave! [grabs the stone and gets obliterated]
Drax the Destroyer: [getting drunk in a bar] Let us put more of this liquid into our bodies.
Yondu Udonta: I may be as pretty as an angel, but I sure as hell ain't one.
[first lines] Grandpa: Peter. Your momma wants to speak with you. Come on, Pete, take these fool things off. [takes headphones]
