Dragon Ball Z: The Tree of Might, also known by its Japanese title or Toei's own English title Super Battle in the World, is a 1990 Japanese anime science fantasy martial arts film and the third Dragon Ball Z feature film. It was originally released in Japan on July 7 between episodes 54 and 55 of DBZ, at the "Toei Anime Fair" film festival, where it was shown as part of an Akira Toriyama-themed triple feature titled Toriyama Akira: The World (the other two films were anime versions of his one-shot stories Kennosuke-sama and Pink). Plot 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. After Gohan fights back against the henchmen, Turles enters the fray after realizing Gohan is part-Saiyan and deduces that he is Goku's son, who he states is from the same class of Saiyan warrior and thus explains their similar appearances. Gohan impresses Turles with his power level and is invited to join his conquest, but he refuses and attempts to fight Turles before Piccolo intervenes to rescue him. Turles forces Piccolo to protect Gohan and the Namekian is dispatched. Turles creates an artificial moon and forces Gohan to observe it, causing him to transform into a great ape (oozaru), who attacks Goku but is calmed by the appearance of Icarus. Turles injures Icarus with an energy blast, causing Gohan to go into a frenzy before Goku severs his son's tail with an energy disc,
