Comment(s):

First appearance of the Transmatter Cube.
During All-Star Squadron #50, a large group of heroes from Earth-Two migrate to the heroless Earth-X. It is not known if any move back to Earth-Two before this story, or any other heroes follow them. Several of the heroes shown in the migration have post-World War II adventures that do not show a Nazi-dominated world. It is possible that the stories shown take place on another Earth that have these heroes, but history takes the course shown on Earths One and Two. (This Earth is commonly called Earth-Q (for Quality) in the fan writings about this subject, but not officially recognized by DC Comics)
A post-Crisis version of this story was recounted in Countdown #46/2 (August 2007 [June 13]): "History of the Multiverse, Chapter Four"

Story Reprinted in:
