PO'd Sundipped Superman vs Marvel Earth
Lex Luthor murders Lois in a horribly gruesome manner (hacking her to bits) and then brings her remains (what's left of it) to Superman while sobbing. Lex tells Superman that he and his scientists tracked Lois' remains after she went missing a month ago (after Lex kidnapped her). Superman, who normally would have called Lex on this blatant lie, had been so distraught that he couldn't think clearly and accepted Lex's lies. Lex then tells Superman that the culprits came from a universe similar to DC's, called the Marvel Universe. Lex then tells Superman that through various machinations, he's worked out a deal with Marvel Universe's devil, Mephistor to restore Lois if and only if Superman kills every super-powered being on that planet. Superman, who had been in the center of the sun for a week, has gone partially insane from Lois' disappearance and from the prolonged solar absorption, no longer has his morality checks. He agrees to destroy Marvel earth's meta-humans. Superman is cackling with solar electricity, his eyes burning red, he steps into Lexcorp's transporter and in an instant is transported to Marvel Earth. He lands in Time Square. Will he succeed in killing every metahuman on Marvel Earth?
