A forest fire interrupts a camping trip enjoyed by Gohan, Krillin, Bulma and Oolong. Gohan and Krillin manage to put out the fire and use the Dragon Balls to restore the forest and the animals that were killed by the inferno, and Gohan befriends a small dragon he names Icarus. Unbeknownst to the group, the fire was started by a probe sent by a Saiyan space pirate named Turles, who bears a striking resemblance to Goku and who has chosen the Earth to plant the tree of might, which absorbs the life of a planet and converts it into fruit that when eaten, gives the consumer a massive power increase. Turles' henchmen plant the seed and King Kai telepathically warns Goku of the danger. He, Krillin, Yamcha, Tien Shinhan, and Chiaotzu attempt to destroy the tree using energy blasts but fail. Turles' henchmen attack and overwhelm them. The Earth begins to succumb to the devastation of the tree's life absorption as water vanishes and plants and animals begin to perish.
