Clark Kent: I have so many questions. Where do I come from?
Colonel Nathan Hardy: You're right: a good death is its own reward.
Lois Lane: Welcome to the Planet.
Jor-El: You've grown stronger here than I ever could have imagined. The only way to know how strong, is to keep testing your limits.
General Zod: No matter how violent, every action I take is for the greater good of my people.
Faora: You will not win. For every human you save, we will kill a million more.
Lois Lane: How do you find someone who has spent a lifetime covering his tracks? For some, he was a guardian angel. To others, a ghost who never quite fit in.
Jonathan Kent: You're the answer, son. You're the answer to "are we alone in the universe."
Clark Kent: Can't I just... Keep pretending I'm your son?
Jonathan Kent: You ARE my son. And I have to believe that you were sent here for a reason. And even if it takes the rest of your life, you owe it to yourself to find out what that reason is.
General Zod: My name is General Zod. For some time, your world has sheltered one of my citizens. I request that you return this individual to my custody. To Kal-El, I say this: surrender within 24 hours, or watch this world suffer the consequences.
Clark Kent: My father believed that if the world found out who I really was, they'd reject me... Out of fear. He was convinced that the world wasn't ready. What do you think?
Answer: Kryptonians aren't invulnerable. It just takes a lot to hurt one after he has been charged by our yellow sun. There are several beings who are strong enough to break a Kryptonian's bones. Doomsday, Darkseid, etc. Since both are roughly equal in strength on Earth, its no different than one human breaking another's neck.
