You stupid, stupid Kryptonians. You just don't understand, do you? You think locking up Bizarro, Silver Banshee, Parasite, and the rest will make things easier for you? You think it'll mean you jerks can just waltz across the earth without a care in the world?
You're idiots. You're arrogant and smug. You think because you had this great society and you have these super-powers that you're something special. That you're far above we mere humans. But I've got news for you all. When you locked up all of Superman's foes in the Phantom Zone you forgot someone:
I don't know why you overlooked him. Maybe you couldn't find him. Maybe you think a bald scientist is less of a threat than the Prankster. Perhaps you thought the intellect of a human being could never compare to that lauded Kryptonian science.
There's a reason why he's Superman's greatest enemy. And you, my Kryptonian friends, are not on Superman's level. Luthor will destroy you. You should leave. You should run away. You should get off this planet before it's too late. Because Superman can handle Luthor. But y'all ain't no Superman.
He's going to kill you. He's going to kill you all if you don't get away. You can stop Doomsday. But you can't stop Lex Luthor.
