Earth-21

Earth-21 is a parallel Earth on which Nazi Germany won World War II. Hitler realized his dream of conquering the world, though it took him until the 1970s finally to subdue North America. He died shortly thereafter, and his son, Rolf Hitler, succeeded and is currently ruling as absolute Ddctator (called "der Führer"). The Nazis spent a good deal of time researching superpowers once they surfaced on Earth-21, and their policy is: serve the State or die. Many resistance super-fighters have been executed, and mostly what's left are the superhumans who serve the Nazi regime. These are called "heroes" on Earth-21, and the resistance fighters are called "villains."

This is the world from which the WormHole Gang hails (and where they are currently).
