"Think about it, Clark. My intellect, your powers. Together we could rule this world. We'll walk as gods among men. [...] Every man has a weakness, Clark, no matter how superhuman he may be. I've embraced my destiny. Now embrace yours. We could forge a new future together."
"President? ...Foolish, faceless man; my campaign is a farce. A small part of a much grander scheme. [chuckles] 'President'... Do you know how much power I'd have to give up to be President? That's right, conspiracy buff. I spent 75 million dollars on a fake Presidential campaign, all just to tick Superman off."
"I'm the only sane inmate of Asylum Earth. I'm not eager to hand tomorrow over to an interplanetary extremist with laser eyes. There's only room on this world for one leader, Superman. When I'm finished with you, every last gibbon out there will know you for the menace you are... and they'll realize that Lex Luthor is their savior."
— Lex Luthor
"I am Lex Luthor. I am the greatest scientist on this planet, and would be on yours as well."
"In a cosmos like ours — if you accept the "Big Hand theory" of the universe's origin — deciding on atheism isn't a logical choice. it's an ethical one. If there is a God, if he turns out to be ... a little man in a bowler hat or something, do I at least get to put forth my case? Do I get to argue?"
"No man in the sky intervened when I was a boy to deliver me from daddy's fist and abominations. I figured out way back: if God is all-powerful, He cannot be all good. And if He is all good, then He cannot be all-powerful. And neither can you be. They need to see the fraud you are... with their eyes."
"Attack me? Do you know what happens when you take on Lex Luthor? (starts shooting Parasite in the face until he runs out of bullets, then throws the gun at him and proceeds to kick and punch at him) The same thing, that's gonna happen, to Superman!"
Lex: You see, sis...we, as a people, have become soft. And fat. And stupid. Voice: This is the Metropolis Police Department! Surrender! Lex:[taps his watch and blows up the police helicopter] Where was I? Lena: My God, Lex, you killed them. Lex: Oh, that's right! We must put faith in ourselves. But instead, we look up...to him, with big, glassy eyes, because we think he's invincible. It's my duty to dispel the world of that notion. And when he dies, they will finally wake up and see him for what he really was... a false god. Lena: At least he's a good man. Lex: HE IS NOT A MAN! I WAS THE MAN OF TOMORROW, NOT HIM! NOT! HIM!
