Earth-1B

Earth-1B is the unofficial designation of the universe that the Super Powers series takes place in. Although not exactly the same as Earth-1A, both Earth-1A and Earth-1B share many similarities.

List of similarities

 * In both universes the Justice League are referred to as the Super Powers Team.
 * In both universes the Super Powers Team's headquarters is the Hall of Justice. (Note: On Earth-One, there never was a Hall of Justice)
 * Robin is a member of the team on both earths, whereas on Earth-One, he's only part of the Teen Titans, and he was known as Nightwing at that point.
