While attempting to bridge the prison dimensions of the Phantom Zone and Negative Zone, super-villain Doctor Doom instead uncovers an alternate reality filled with monsters and magic. After conquering the nearby citadel and claiming it as his own, he declares the realm New Latveria. Operating out of Castle Doomstadt, Viktor goes about converting the dimension into his own prison zone. Doom spends the following months sending his minions to selectively capture heroes from various realities, imprisoning and stripping them of power on their arrival. In time, he hopes to return to these vacant realms and claim them as well. That is unless the imprisoned heroes can fight back – and somehow discover a means of escape.
