Dragon Ball Wiki

Planet Zoon (わくせいズン Wakusei Zun, lit. "Planet Zun"), also called Voon, is the home planet of Pui Pui, one of Babidi's minions. It is located in Universe 7.


Not much is said about this planet, other than it having 10 times the gravity of Earth, just like Planet Vegeta, though the appearance suggests that it is a somewhat harsh and desolate place.

Vegeta facing Pui Pui on Zoon

The planet is introduced in the Babidi Saga, when Goku, Vegeta, and Gohan are in Babidi's spaceship. When the three Z Fighters are at Stage One, they use Rock-Paper-Scissors to decide who goes first. Vegeta is the victor, and gets ready to fight Pui Pui. With Vegeta dominating the battle, Babidi transports Pui Pui to his home planet, so that he will have an advantage while fighting Vegeta. However, Vegeta, due to his previous training under 450 times the gravity of Earth, and due to his upbringing on Planet Vegeta which has the same level of gravity, is unaffected by the change in gravity and effortlessly slaughters Pui Pui in minutes using his Double Galick Cannon on him.

Planet Zoon in Dragon Ball Super

The planet is never mentioned again until the Galactic Patrol Prisoner Saga when Moro and his army attacked Planet Zoon and killed its warriors who were protecting the royal treasure. Moro drains the life energy of Zoon, which results in the destruction of the planet and the complete extinction of the Zoon-seijin.

Following Moro's demise at the hands of Goku, the Namekian Dragon Balls are used to restore all the planets and lifeforms that had been lost, including Zoon.

It is mentioned in Dragon Ball Z: Buu's Fury, but does not appear.


  • Zoon means "son" in Dutch.
  • Planet Zoon was referred to as "Planet Voon" in some English dubs. In Buu's Fury, the original Japanese version and Kai, it is called Planet Zoon.
  • Zoon seems to have some features that favor the real planet Mars.
