DBZ History
Five years later Master Roshi is seen at his home with Krillin, and Bulma, waiting for their reunion with Goku and his son, Gohan. The group is soon confronted by a man named Raditz, who reveals he is Goku's brother. He also reveals to Goku that he is a Saiyan warrior and was sent to Earth when he was a baby in order to wipe out all life. Master Roshi informs the confused and shocked Goku of a story that Grandpa Gohan told him. When he was a baby he hit his head and lost his memory, thus Goku lost his violent nature and became a happy, loving boy. Raditz implores Goku to join him in conquering planets, but is refused. However, Goku's son Gohan is kidnapped in order to get Goku to cooperate. Piccolo arrives to help Goku fight, and the two go off to take down Raditz. Later, Krillin, Bulma, and Master Roshi head to the battlefield and find Goku dying, a result of sacrificing himself to kill Raditz. Piccolo informs the group that two more Saiyans will be coming to Earth in one year, and that they are far more powerful, with Piccolo taking Gohan to train for the invasion.

A year later, the Saiyans arrive and Master Roshi, Bulma, Oolong, Puar, Ox-King, and Chi-Chi watch the battle on TV. They watch Yamcha fall, but the TV network shorts out, and they are unable to watch the continuing carnage, as Tien Shinhan, Chiaotzu, and Piccolo all fall on the battlefield as well. Later they go to the battlefield to retrieve their injured friends, Krillin reveals the home world of Piccolo is a place named Namek where there are another a set of Dragon Balls that could be used to revive their fallen friends (as when Piccolo died, Kami did as well, rendering the Dragon Balls inert).

Master Roshi watches as Bulma, Krillin, and Gohan blast off into space, headed for Namek. Roshi is called by Bulma after they had arrived on Namek, but revealed the horrible news that Vegeta and a stronger being named Friezawere on the planet as well. Master Roshi visits Wukong Hospital to tell Goku of the trouble on Namek. Later, Master Roshi is seen at Capsule Corporation with his friends who are worried about Goku, Gohan, and Krillin as they struggle to survive against Frieza on Namek. Later, after Chi-Chi asked Dr. Brief to build a second Capsule Corporation spaceship, she took Master Roshi, Yajirobe, Puar and Oolong with her to go to planet Namek. While Goku as a Super Saiyan was fighting Frieza, their attempts to fly were always cancelled either because of a breakdown of the spaceship or because of getting messages from the group on Namek. When Goku is revealed to have survived Namek's destruction, but refuses to come home yet, Roshi ends up yelling in frustration that Goku's reason for not returning is that he's scared of the one being that is more powerful than a Super Saiyan: Chi-Chi, Goku's wife, only for him to immediately recant the remark after Chi-Chi, overhearing the remark, starts holding a sword out with the intent of stabbing him with it.
