Dragon Ball Z Side Story: Plan to Eradicate the Saiyans

Plot

Dr. Raichi (Dr. Lychee) is one of the only survivors of the Tuffles, a race that once lived on Planet Plant before the coming of the Saiyans. The Saiyans not only massacred the entire Tuffle race, but also stole their technology and conquered the planet, renaming it Planet Vegeta in honor of their king. Raichi managed to escape with a capsule and found refuge on the Dark Planet, a world at the end of the universe. His only wish is to eradicate the last remaining Saiyans.

To do this, Dr. Raichi puts devices on Earth that emit Destron Gas and destroy all life. When Mr. Popo finds out that only a few hours are left until the planet's destruction, Goku, Gohan, Vegeta, Trunks, and Piccolo rush to destroy the evil devices located around the planet. They manage to destroy all but one that is protected by an impenetrable energy barrier. However, Freeza, Cooler, Turles and Slug appear and engage the heroes in individual fight. It is revealed by Kai-sama that the villains are ghost warriors, and will continually come back to life when killed unless defeated in the same way their lives were originally ended.

The heroes track Dr. Raichi down to the Dark Planet and engage him, discovering that his ghost warriors are generated by a machine called Hatchihyack, a device powered by the hate of the Tuffles. It is also revealed that Dr. Raichi is a ghost warrior himself, generated by Hatchihyack. When Vegeta vaporizes Raichi, preventing him from re-materializing, the hate Dr. Raichi had causes Hatchihyack to exceed its limit. Hatchihyack appears in a powerful android body, whose power is said to match or perhaps even exceed Broly's, according to Goku. Hatchiyack devastates the heroes until the Saiyans, after having transformed into their Super Saiyan states, combine their powers together into one massive wave of energy, ending the threat of the ghost.

Phantom versions of Turles, Cooler, Lord Slug and Frieza appear when the Z Fighters reach the last of the Destron Gas generators. In the battle, Turles decides to fight against Gohan, and he is beating the young half-Saiyan until the pollution caused by the gas weakens Gohan and the other Z Fighters Ghost Turles is able to put up a good fight against Super Saiyan Teen Gohan

Turles appears as a Ghost Warrior in the Famicom game Dragon Ball Z Gaiden: Saiyajin Zetsumetsu Keikaku and its Playdia adaption Shin Saiyajin Zetsumetsu Keikaku - Chikyū-Hen, but is eventually killed again, this time by Gohan. In an alternate ending in the Playdia version, Turles is much stronger then gohan is and ends up killing Gohan instead. In addition to the Ghost Warrior version of Turles who appears as a boss, Mirage Turles (ターレスミラージュ; a green-skinned Turles with pink armor) and Phantom Turles (ターレスファントム; purple-skinned Turles with blue armor) appear as regular enemies in Saiyajin Zetsumetsu Keikaku.

Hatchiyack

The main villain from Dragon Ball Z Side Story: Plan to Eradicate the Saiyans. Hatchiyack is an android whose strength is fueled by the previously beaten villains' hatred for Saiyans. He comes to full power and materializes once Vegeta destroys Dr. Raichi, and is estimated by Goku to rival or exceed Broly's strength. He had many different forms in alternate endings, including a giant form, a multi form, and a super form.
