I always thought it was a little odd that the Super Dragon Balls only scatter among the 6th and 7th Universes, rather than possibly ending up in any of the twelve, but I think I just realized why they only end up in those two universes and it’s so obvious in hindsight...
Those are the universes that have Namekians!
The only species known that has the inherent magical power to create their own lesser sets of Dragon Balls.
That pretty much confirms (in my mind) that Zalama, the “Dragon God” who originally created the Super Dragon Balls who-knows-how-many years ago, must have been some super powerful ancient Namekian... or at least is closely related to the Namekians in some way, even if he’s not technically one of them. If he was just another distant, detached higher godly figure like the Gods of Destruction, Angels, Zen’oh, etc. are he probably wouldn’t have designed his creations to stick specifically to the two universes where his people (either by birth or association) happen to live.
Who knows if he’s still alive (the Super Dragon Balls still being active could imply that their creator is still alive, but... the Super Dragon Balls don’t have any of the other restrictions that lesser sets have, so it’s possible they don’t have the restriction of “stops working when the creator dies“ either!), or if we’ll ever actually see him, but still.
Famed manga creator Akira Toriyama has passed away on March 1, 2024 at age 68 due to acute subdural hematoma.
Toriyama began his first serialized manga, Dr. Slump, in 1980, and it inspired two television anime and multiple films. Toriyama followed it up with Dragon Ball, which ran from 1984 to 1995, and is still inspiring manga and anime sequels and spinoffs today. The manga's Dragon Ball anime adaptation, its sequel Dragon Ball Z, and its other numerous sequels and anime films are equally as well-known as the manga, and its hero Goku has become a character known throughout the world.
Toriyama is also well-known as the character designer for the Dragon Quest, Chrono Trigger, Blue Dragon and Tobal games.
Most recently, Toriyama was working closely with the production for the Dragon Ball Daima anime series, the most recent anime series based on Dragon Ball, and is credited for the new anime's story and character designs.
Almost like all Latin American children, I grew up watching Dragon Ball, and in fact it was one of my biggest inspirations to improve my art. The mark that Akira Toriyama has left on us will never disappear.
