"[about his home planet] It was, and it was beautiful. Titan was like most planets, too many mouths not enough to go around, and when we faced extinction I offered a solution. Random, dispassionate; fair to rich and poor alike, and they called me a mad man. I'm a survivor."

"With all six stones, I could simply snap my fingers and they would all cease to exist. I call that... mercy."

"I finally rest and watch the sun rise on a grateful universe. The hardest choices require the strongest wills."

"A small price to pay for salvation."

"[to Heimdall] That was a mistake."

"Reality is often disappointing. That is, it was. Now, reality can be whatever I want."

"[to Doctor Strange] You're full of tricks, wizard... but you never once used your greatest weapon. A fake."

"[to Tony] You have my respect, Stark. When I'm done, half of humanity will still be alive. I hope they remember you."

"This universe is finite, its resources finite. If life is left unchecked, life will cease to exist. It needs correction. I'm the only one who knows that. At least, I'm the only one with the will to act on it."

"[Last words] Something's happening."

"Kick names, take ass."

"I'll do you one better. Why is Gamora?"

"[Last word] Quill?"

"[Last words] Allfathers, let the dark magic... flow through me one last... time."

"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. But 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."

"[Last words] Steve?"

"Well, for one thing, I'm not Asgardian. And for another... we have a Hulk."

"[Last words] You... will never be... a god."

"The entire time I knew Thanos, he only ever had one goal: To bring balance to the universe by wiping out half of all life. He used to kill people planet by planet, massacre by massacre. [Drax the Destroyer: Including my own.] If he gets all six Infinity Stones, he can do it with the snap of his fingers, like this."

"Did you do it? [Thanos: Yes.] What did it cost? [Thanos: Everything.]"

"[Last words] It's alright. It's alright. I love you."

"YIBAMBE! [Pronounced "yee-bam-Ba": Xhosa for "hold strong"]"

"Wakanda forever!"

"[Last words] [Thanos: I understand, my child. Better than anyone.] You could never. [Thanos: Today, I lost more than you can know. But now is no time to mourn. Now... is no time at all.] [Thanos uses the Time Stone to resurrect Vision] NO!!!"

"[to Wanda] I understand, my child. Today, I lost more than you could know, but now is no time to mourn; now is no time at all."

"[Last words] Up, General! Up! This is no place to die."

"I'm Peter, by the way. [Dr. Stephen Strange: Doctor Strange.] Oh, we're using our made up names. Um... I'm Spider-Man, then."

"You can't be a friendly neighborhood Spider-Man if there's no neighborhood."

"Mr. Stark, I don't feel so good."

"[Last words] I'm sorry."

"[Steve Rogers: How you been, Buck?] Not bad, for the end of the world."
