Whenever the world is threatened by unnatural dangers, there is only one organization to call on. The League of Extraordinary Gentlemen has existed for centuries, recruiting the finest and most unusual adventurers, thinkers, rebels, and iconoclasts the universe has ever seen. When Dr. Oak summons a coterie of evil dictators and would-be conquerors to bid on his genetically engineered army of monsters and child trainers, it is up to the League to stop him. Three heroes are sent in to stop the sale of the ‘Pocket Monster’ army: Earthworm Jim, The Guyver, and MANTIS. Can they penetrate the island’s security and stop Dr. Oak before it is too late?
