"The Earth wakes up one day to a brand new world order--one in which Superman and Batman rule with an iron fist. Humankind has a choice: obey or die. How did things get this way? And is anyone left who can stop them? Before long, the World's Finest Duo is sent careening through a series of bizarre alternate Earths, facing an assortment of classic DC characters, including Kamandi, Sgt. Rock, Haunted Tank, and many more!"--Provided by publisher.
