Now that the World's Greatest Heroes have gone international, even more members are joining their ranks-making it the most unlikely grouping of heroes yet! Batman, Blue Beetle, Booster Gold, Martian Manhunter, Guy Gardner, Mister Miracle, Captain Atom, Rocket Red, Fire, Ice, and...the Huntress? But will this ragtag group be able to get it together in time to handle the intergalactic meances of Lord Manga Khan, the hordes of Apokolips, and an alien invasion of Earth? Can the team really survive splitting into two separate groups to better cover the glove? Who will join their European branch? And why is Blue Beetles attempting to kill Maxwell Lord?
