The Ultimate Sacrifice
Superman, Hal Jordan, Silver Surfer, and Thor have been summoned by a mysterious entity.
He gives them this ultimatum: Decide amongst yourselves who shall sacrifice his life so that both of your respective universes shall survive!
The heroes discuss amongst themselves who should give up his life. Naturally, all of them volunteer their own life. But in the end, they must agree on one person.
Who would it be and why?
