#4 out today.
Wowee.
100/100. Seriously awesome.
First we get Jimmy Olsen, who is a columnist for the Daily Planet who writes a very popular piece called "For A Day" in which he becomes someone for a day - at the opening of the story it's "I Was America's Sweeetheart For A Day" and he's standing there in a bra and wig while his girlfriend who is berating him for being the "Worst Dressed Man in Metropolis" for the second year in a row. Funny.
His next piece is "I Was P.R.O.J.E.C.T. Directory For A Day" - he gets a tour of the place, including a mysterious vault labeled "DO NOT OPEN UNTIL DOOMSDAY" - "Doomsday is a legacy of P.R.O.J.E.C.T.'s origins in the US Army's Cadmus Division."
Jimmy is walking around on his tour and accidently almost falls into a "world of supergravity - "a newly discovered basement level hidden beneath the known structure of the universe." He calls Superman for help using a signal watch - Clark Kent is in a meeting at the Daily Planet and rushes off.
He saves Jimmy, but he is shown something that P.R.O.J.E.C.T. found recently - black Kryptonite. It turns out black Kryptonite turns Superman into "everything [Superman] is not" - that is - Bizarro Superman!
So Superman is evil and goes back to Earth to do who-knows what, so Jimmy , as acting head of P.R.O.J.E.C.T., calls upon Doomsday, which is a sort of serum that he uses on himself, turning him into a grey monster with bones sticking out all over him - Doomsday! He beats Superman into submission, the black Kryptonite wears off, and all is well. And Jimmy has "I Love Lucy" carved into the moon for his girlfriend.
This was the greatest Superman issue ever created.
