Superman and Batman may hold the title of World's Finest, but Mr. Mxyzptlk and Bat-Mite are definitely the World's Funnest! In this long forgotten tale Mr. Mxyzptlk and Bat-Mite battle across the entire multiverse and almost every character you can think of is along for the ride! Plus, when a cosmic storm passes over planet Earth, it brings a mysterious plague which nearly kills the entire male population with the only two men who survive are Superman and his arch-nemesis Lex Luthor! In Elseworlds, heroes are taken from their usual settings and put into strange times and places--some that have existed, or might have existed, and others that can't, couldn't or shouldn't exist. The result: stories that make characters who are as familiar as yesterday seem as fresh as tomorrow.
