Bizarro has a problem. The cloning technology he received from Lex Luthor worked a little too well. Instead of creating a few duplicates to keep him company on his home world, Bizarro created 100 doppelgangers and they've all turned against him. With nowhere to turn, Bizarro asks the world's greatest super heroes including Superman, Supergirl, Batman and Wonder Woman for help. Can the Justice League take down Bizarro's doppelgangers of doom? Or will Bizarro World collapse under complete clone chaos?
