Doom had asked the wrong person, really, because Deathstroke knew that the Beyonders did indeed have one extremely important place.
That was their Reproduction Center, or perhaps their assembly line?
The vast majority of Beyonders, aside from rare exceptions like CCU, were born in the Beyond Realm, assembled like machines on a production line.
As a race, they needed to reproduce. Rather than relying solely on the realm automatically gathering energy to form life, it was better to keep the power of reproduction in their own hands.
And that was exactly what they had done. Thus, they had a highly classified facility much like a cannery. There, concepts, matter, and energy were pieced together, then a Single Universe was placed in a culture dish and a fertilized egg tossed inside. Before long, a new Beyonder would grow out of it.
Different grades of Beyonders had different manufacturing processes. If they wanted one to possess higher authority in the future, then the materials used during its creation had to be more carefully selected, and its subsequent cultivation had to differ as well.
It was a little like a bee colony. Give a larva a big "room" and feed it royal jelly, and it would grow into a queen bee. Give the same larva nothing but honey, and it would become a worker bee.
The difference in development was related to differing energy intake.
There were differences, however. In essence, Virus and the Ivory Kings were not all that different. Both were shapeshifting robots. So long as they were not cannon-fodder units like Starro and the Cartographers, standard Beyonder individuals could draw quotas from the Beyond Realm's "energy pool," allowing them to display different forms.
Starro, also translated by some as Sidera Maris, were basic engineer units made by the Beyonders from
