Dr. Doom by Jack Kirby - "Now, it is I who possess the cosmic powedr which once was his! Never before has any one human being been as totally supreme... As invincibly superior... As I! Now let mankind beware... For Doctor Doom has attained powers without limit... Power enough to challenge Galactus himself!"
