Planet Frieza 79

Planet Frieza No. 79 is a planet that was dominated by Frieza. The only inhabitants seen on the planet are men under Frieza's command. This also seems to be a prominent base of operations in Frieza's empire.

Overview
Planet Frieza 79 is first seen when Vegeta recovers there after his battle on Earth. When Frieza calls the Ginyu Force, they can be seen (in shades), preparing for their 5 days journey to Planet Namek with their supporting Frieza's henchmen who dealt with their logistics and launching. Later, during Goku's battle with Frieza, Planet Frieza 79 is shown along with Frieza's soldiers; an alien who is of the same race as Cui asks the other henchmen if they support Frieza. Most of the base then ends up heavily damaged after the base's scouter system malfunctioned and self-destructed while monitoring Frieza and Goku's power during their battle on Planet Namek.

Video Games
Frieza No. 79 is seen in cutscenes in Dragon Ball Z: Supersonic Warriors and Dragon Ball Z: Budokai. It is explored by Vegeta in Dragon Ball Z: Harukanaru Densetsu; it is where Appule, Banan, Sūi, and Cui first appear in the game.

The planet stage in the Budokai Tenkaichi series seems based on Frieza No. 79.

Trivia

 * Frieza No. 79 looks very similar to Planet Kanassa. Kanassa could have been renamed "Frieza No. 79" after Bardock's Elite exterminated the planet's residents.
