Steve Englehart tied in the Beyonder to these older characters for his "Secret Wars III" story in Fantastic Four #318-319 (September-October 1988). According to Englehart, an editor hated the character and ordered the Beyonder "removed" from the Marvel Universe. Englehart did as asked but has stated that he tried to exile the character with dignity. The character was subjected to a retcon making him less potent than originally determined, and explanations of his omnipotence have been written off as the more powerful beings "playing along" to ease the Beyonder's transition into self-awareness. It was explained in Secret Wars III that the Beyonder was in fact a Cosmic Cube. During the first Secret War, the Beyonder claimed to be the embodiment of an entire universe. As he became self-aware, he recognized himself as the only person in his universe. Secret Wars III revealed that the Beyonder is in fact a wayward Cosmic Cube, at one time inhabiting his own "dimension" because there was no matrix to hold his energy. The Beyonder took his name from the powerful Beyonders who were manipulating his destiny.
The Beyonders received an entry in the Official Handbook of the Marvel Universe Update '89 #1.
