Dragon Ball Z: Plan to Eradicate the Super Saiyans

Dr. Raichi is the last survivor of the vanished Tuffle civilization. His people were wiped out by the warlike Saiyans, who wanted their resources; the invaders renamed the planet and drove out its former inhabitants. Raichi has nursed his hatred ever since, swearing revenge. Hiding in an underground complex, the scientist begins experiments aimed at the total extermination of the Saiyans. He develops the Destron Gas, a toxic substance that is lethal when inhaled, and places special containers of it all over Earth. Mr. Popo learns of the catastrophic threat and warns the heroes.

Goku gathers a team to find the devices. The fighters split up and head to different locations, and the heavily protected machines take real effort to destroy. The friends wreck almost all of the gas tanks, but the last one sits in a heavily guarded spot. The clock is ticking and the stakes keep rising. Raichi activates a backup protocol and summons phantom warriors, images of dead enemies that force each hero to face the ghosts of the past. In the final showdown Goku challenges Raichi himself, and the fate of the planet rests on the outcome.
