The mischievous imps - Mr. Mxyzptlk and the Bat-Mite - have a little tactless fun with their buddies Batman and Superman. It begins with a Superman and Batman adventure in the style of their classic Silver Age stories in World's Finest Comics, with their superheroic activities interrupted by their pesky mystical opponents, Mr. Mxyzptlk and Bat-Mite. But the comedy turns very dark as the imps accidentally kill our heroes in a saga that takes them on a destructive rampage through nearly every universe DC has presented.
