Superman/Batman: World's Finest

They are the World's Finest heroes, Superman and Batman, and they couldn't be more different. One is a bright, shinning beacon of hope and protector to the citizens of the sparkling city of Metropolis. The other hides in shadows and strikes fear into the evildoers that dwell in the crime-ridden Gotham City. But they have more in common than they realize. For one, they're both orphans of a sort, one who has lost not just his parents, but his world; and another who witnessed the cold-blooded murder of his partents. Now they must come together to battle two of the most feared villains - Lex Luthor and The Joker.
