Alexander Luthor, Sr. (Earth-8026)

"I respect you, Superman. I truly do. But I can't trust you. With all your immeasurable power, there's no telling what you could possibly do, who you could possibly hurt. So yes, I am going to dedicate everything I have to bringing you down. Hypothetically, of course, should we ever need to. You have to understand that as a man in my position, I simply can't take that risk."

- Lex Luthor
