- Crisis On Infinite Earths: Absolute Edition identifies Earth-154 as the original universe featured in World's Finest #154 and Earth-216 as the "Super-Sons Earth" which first appeared in World's Finest #215. However, for indexing purposes, the DC Database has chosen to use Earth-154 as the main universe designation for the stories featuring Batman, Superman and their offspring. It is considered that this "merger" doesn't affect continuity since there are no indicators that both Earths contradict their respective timelines.
- Mark Gruenwald in Omniverse #1, 1977 named this reality "Earth-E", presenting several features that separated it from both Earth-Two and Earth-One.
- In World's Finest #263 (1980) it was revealed that this was a simulation created by Superman and Batman on the Man of Steel's computer in his Fortress of Solitude.
