Piccolo decides to train Gohan to see if he is able to use his hidden powers to defeat the Saiyans, whereas Goku is brought to the Other World by Kami to train with Kaiō-sama. After running along the Serpentine Road, Goku meets Kaiō-sama and starts training with him under strong gravity. After finishing his training, Goku is revived by the Dragon Balls, but he is forced to run again if he wants to return to Earth. The two Saiyans, Vegeta and Nappa, arrive on Earth and confront the opposing warriors Piccolo, Gohan, Kuririn, Yamcha, Chaozu and Tenshinhan. Nappa creates plant-based monsters known as Cultivars (栽培マン, Saibaiman) that fight the warriors, with one managing to kill Yamcha with a suicide attack. After Kuririn and Piccolo destroy all of the Cultivars, the group is confronted by an angry Nappa.
