Just underneath however is the twin reality known to the Hand's pioneeringly perverse fictonauts as the "Paperverse", once home to the likes of The Status Quorum and Flex Mentallo, itself linked to other worlds by way of the enigmatic H-Dial. In the wake of the war against the Lost Operator however, it is a shell of what it once was, with only faded rumors of the fabled Legion of Legions watching overhead. Ultimately, both dimensions merge through the efforts of psychic Wallace Sage, leading into the future of Seaguy (said by Morrison to take place 50-70 years into the future of a world resembling our own).
Earth 24: A world where a revolutionary Superman has brought total freedom to the masses, but this has led to anarchic chaos.
Earth 25: Superman Red and Superman Blue.
Earth 27: A 'realistic' Earth not unlike Marvel's Ruins (Batman died his first night out when his grapple gun snapped, Green Lantern and Flash have no control over their powers, Themyscira was bombed to ashes within a few years of revealing itself), with a disturbed 'Superman' - possibly Overman - that acts as a parody (in that this unwitting self-parody can have such a treatment performed on it) of the Superman of Earth One.
Earth 28: An anime style Earth defended by a martial arts, chi-wielding warrior Wonder Woman, the spirit of vengeance titled the Bat-Man (seen in the DC Nation short 'Batman of Shanghai'), a young Clark Kent inheriting a Kryptonian space-watch allowing him to command the mighty Super-Mecha, a magical Green Lantern in the style of Sailor Moon, and an Astro Boy type robot gifted life and a connection to the Speed Force in a lightning storm becoming the super-swift Flash.
Earth 46: A swords and sorcery-ish Earth ruled by superhuman dynasties reluctantly entering its first industrial revolution, with more than a passing resemblance to Moore's Twilight of the Superheroes pitch.
Earth 49: A peaceful world guarded by the JLAngels, including Superangel (Zauriel), the Spectre, Lightray, Deadman, Doctor Fate, Dove, and Willoughby Kipling, the Heaven-Bearer.
