Plot
Dr. Raichi 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, Future 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, Frieza, Cooler, Turles and Lord Slug appear and engage the heroes in individual fight. It is revealed by King Kai 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. Lychee down to the Dark Planet and engage him, discovering that his ghost warriors are generated by a machine called Hatchiyack, a device powered by the hate of the Tuffles. It is also revealed that Dr. Lychee is a ghost warrior himself, generated by Hatchiyack. When Vegeta vaporizes Lychee, preventing him from re-materializing, the hate Dr. Lychee had causes Hatchiyack to exceed its limit. Hatchiyack 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.
