Good ol' Bizarro World!
Bizarro World's origin is explained! The backwards planet was created when Bizarro originally left Earth, using meteors to sculpt a cubical planet and build his own version of Metropolis.
But how are there Bizarro people, you ask? Well the blue sun the new planet orbits had given the duplicate new powers, allowing him to create Bizarro versions of the people of Metropolis.
However, Bizarro now regrets creating the world, and seeks his "father's" guidance on how to undo it. Problem is, his backwards mind has mixed up John Kent with Jor-El. So he takes John to his version of the Fortress of Solitude to ask him for guidance.
Elsewhere the Bizarro Lex Luthor has a new plan to save the world from the menace. And guess what THAT is!? It's hilarious. However, the plan goes down the tubes when the Bizarro JLA appears!
I got some laughs from this one. And the art's still great.
