* In 1993, Toei Animation, in cooperation with Shounen Jump and V-Jump, produced a two-part OVA that served as a video strategy guide to the Family Computer game titled Dragon Ball Z Gaiden: Saiyajin Zetsumetsu Keikaku. This OVA was remade for the PlayStation 3 and Xbox 360 video game Dragon Ball: Raging Blast 2. Dr. Lychee may be the last of the Tuffle people, a race that was completely wiped some time ago by the Saiyans. He now plans to take revenge on the remaining Saiyans, Goku, Vegeta, Trunks, and Gohan. He creates a machine that will emit Destron, a gas that could destroy all life on Earth. The Saiyans, plus Piccolo, only have 72 hours to destroy this machine and find Dr. Lychee. Source: Wikipedia
