Cosmology

Long referred to from a distance as the origin of certain antagonists, the Demon Realm becomes a place in its own right in Daima: political hierarchies, its own geography, and a wish device distinct from Earth’s and Namek’s.

It is the major cosmological contribution of the last series Akira Toriyama followed.

Namek is a green-skied planet whose population was cut down to a few dozen individuals by a climate catastrophe. Its dragon balls are larger, grant three wishes and answer to a dragon that only honours requests spoken in the Namekian language.

The planet is destroyed during the saga that bears its name, then re-established elsewhere under the same name.

You reach it by walking a million kilometres of suspended road, which is already the first part of the training. The ground is a few hundred metres across and its gravity pins anyone who arrives unprepared.

This is where the Kaiô-ken and the Spirit Bomb are taught, and where the story establishes that a dead man can keep improving.

Planet Vegeta is described as a vassalised warrior monarchy whose population supplied a planetary clearance service. Its gravity, ten times Earth’s, explains its inhabitants’ physical advantage.

Its destruction is presented by Frieza as a meteor accident, a lie that structures several characters’ motivation across several series.

In Universe 7, Sadala vanished before the story begins and the Saiyans settled on the planet that took their king’s name. In Universe 6 it still exists and hosts a society that avoided vassalisation.

That symmetry works as a narrative argument: the same race, two trajectories, no inevitability.

Dragon Ball’s Earth mixes megacities, deserts, isolated villages and capsule technology that fits a house in a pocket. Its cosmological peculiarity is having inherited a guardian from Namek, and therefore a wish-granting device no other planet in the quadrant owns.

That anomaly explains why it is coveted by actors with no interest whatsoever in its inhabitants.

Populated by physically weak but technically advanced inhabitants when it comes to movement, Yardrat barely appears on screen yet leaves the franchise one of its most-used abilities. The contrast is deliberate: the story’s best mobility technique does not come from a people of fighters.
