Dragon Ball Z Side Story: True Plan to Eradicate the Saiyans - Space Saga

Dragon Ball Z Side Story: True Plan to Eradicate the Saiyans - Space Saga is an interactive animated game released in Japan on December 16, 1994, for the Playdia console. Like its companion game Earth Saga, it is composed entirely of branching animated sequences. Players make choices at decision points within the animation, and correct selections advance the story while wrong choices result in defeat or a bad ending. The format requires no traditional combat input, functioning instead as an interactive film experience.

Space Saga adds a meaningful branching element tied to the choice of which planet Goku explores during his journey to the Dark Planet. Choosing the first planet leads Goku to encounter sea monsters, culminating in a battle where he uses the Spirit Bomb to defeat Super Hatchiyack. Choosing the second planet brings him into contact with a talking stone face and a fairy, and the final confrontation takes the form of Giant Hatchiyack instead. This branching structure means that different playthroughs lead to meaningfully different final encounters, giving the game replay value beyond a single run.

The Z Fighters active in this half of the story include Goku, Gohan, Piccolo, Vegeta, and Future Trunks, all represented in the animated sequences. Supporting characters such as King Kai, Bulma, Korin, Yajirobe, and Master Roshi also appear, maintaining the full ensemble cast present throughout the Plan to Eradicate the Saiyans narrative.

Space Saga continues the Plan to Eradicate the Saiyans story where Earth Saga ends, covering the Z Fighters' journey into space to confront Doctor Lychee at the Dark Planet. Goku navigates three planets on the way to the final destination, and the outcomes of those planetary visits shape which form of Hatchiyack he ultimately faces. The Dark Planet serves as the setting for the climactic battles against the resurrected ghost warriors and Lychee's supercomputer Hatchiyack.

The space-set scope of the story allows the game to introduce alien environments and characters not present in the Earth-based first half. Alien characters, sea monsters, a talking stone face, and a fairy all appear as interactive figures during Goku's planetary exploration. The narrative concludes the full Plan to Eradicate the Saiyans arc, resolving the Tuffle revenge plot initiated in the original Famicom RPG. A soundtrack covering both Earth Saga and Space Saga was released together following both games, treating them as a single unified work.

Space Saga is the concluding half of the two-part Playdia adaptation of the Plan to Eradicate the Saiyans story, released approximately three months after Earth Saga. The Playdia platform positioned both games as accessible, animation-forward experiences for younger Dragon Ball Z fans rather than technically demanding titles for core gamers. Their reliance on branching animated sequences rather than interactive combat made them unusual within the Dragon Ball game lineup of the mid-1990s.

The branching Hatchiyack encounter at the end of Space Saga is notably the only mechanical variation in the entire two-game series, and it gives the finale a degree of player agency that distinguishes it from the rest of the interactive film format. Both games preserve the visual and narrative content of the Plan to Eradicate the Saiyans OVA in a form that allows limited audience participation, occupying a unique intersection between animated storytelling and interactive media in the Dragon Ball franchise.
