This article is about Dr. Lychee's base. For the planet with a similar name, see Planet Ankoku.

Dark Planet (暗黒惑星 Ankoku Wakusei)[1][2] or (黒い星, Kuroi hoshi)[3] is the planet that is Dr. Lychee's base of operation. The planet was first introduced in Dragon Ball Z Side Story: Plan to Eradicate the Saiyans.



Evil Castle on the Dark Planet in Plan to Eradicate the Saiyans

Dr. Lychee's pod docked on the Dark Planet after he escaped Planet Plant. The planet is the location of Dr. Lychee's fortress: the "Evil Castle", as well as the place of many events in Dragon Ball: Plan to Eradicate the Saiyans.

The Dark Planet is surrounded by giant gas clouds that shoot out purple lightning. This lightning nearly destroyed the Dragon Team's Capsule Corporation Spaceship when they approached the place.

Goku, Gohan, Piccolo, Future Trunks, and Vegeta then travel to the Evil Castle on the planet, where they defeat Dr. Lychee and his supercomputer Hatchiyack in Lychee's Control Center.

Evil Castle in Uchū-Hen

The Dark Planet was introduced in Dragon Ball Z Side Story: Plan to Eradicate the Saiyans. The Z Fighters must defeat four God Guardons in order to open the door to Dr. Lychee's room. Enemies encountered here are Jiku, Budo, Mirage Turles, Phantom Turles, Mind Slug, Mental Slug, Psycho Frieza, Cooler, and Soul Cooler.

It is where Goku faces the final boss Hatchiyack in Dragon Ball Z Side Story: True Plan to Eradicate the Saiyans - Space Saga.

The Dark Planet is a battle stage in Dragon Ball: Raging Blast 2 and Dragon Ball Z: Ultimate Tenkaichi, under the name Planet (惑星).

The Dark Planet appears as a stage in Dragon Ball Heroes, where it appears in several sagas as the setting of battles against Dr. Lychee and Hatchiyack.


  • In Raging Blast 2, the design of the battle stage version of the Dark Planet is nothing like the actual design in the movie and slightly similar to Earth in appearance. Frieza's Spaceship can be seen in the background, possibly a reference to the original Famicom game.
