Collection of 13 Japanese animes and two television specials from the Dragonball Z series. In 'Dead Zone' (1989) Goku (voice of Masako Nozawa) is out fishing when he has a sense of impending doom. When he returns, he finds his son Gohan (Nozawa) has been kidnapped by Garlic Jr (Akira Kamiya)'s henchmen in an attempt to steal the four-star dragon ball from his hat. Goku must prepare for battle to save his son, but this becomes difficult when Garlic Jr summons Shenron (Kenji Utsumi) and wishes for immortality. In 'The World's Strongest' (1990), Gohan and Oolong (Naoki Tatsuta) set out to search for the missing dragon balls which are mysteriously being gathered together. They arrive at the Tsurumai-Tsuburi Mountains' eternal wall of ice, where they find Dr Kochin (Kôji Yada) who summons Shenron and wishes for Dr Wheelo (Kôji Nakata)'s lab to be broken free from the ice surrounding it. As the lab reveals itself, Gohan and Oolong are attacked out of nowhere by the Biomen but they manage to escape. Once free, they must hatch a plan to defeat Dr Kochin and Dr Wheelo before they wreak havoc on the world. In 'The Tree of Might' (1990) a seed from the Tree of Might has been planted on Earth by a group of space pirates. Once it has taken root, the Tree of Might will devour all life energy, leaving the planet a deserted land where no living thing can survive. Goku and his friends try to destroy the tree but find their power is not enough. Suddenly, they are attacked by the evil space pirates, and Gohan is captured by Turles (Nozawa), the pirate's evil leader. Can Goku save Gohan and the planet Earth from Turles? In 'Lord Slug' (1991) a giant asteroid is heading towards Earth, which could mean the end of the world. However, using their special powers, Goku and Krillin (Mayumi Tanaka) come to the rescue and manage to deflect the asteroid. Their triumph is short-lived, however, as the evil Lord Slug (Utsumi) appears from the surface of the asteroid intent on stealing Earth's natural resources and in the process wiping out the entire human race. In 'Cooler's Revenge' (1991) the recently-slain Frieza (Ryûsei Nakao)'s brother Cooler (Nakao) hears of his brother's death and must have his vengeance to protect his family's honour. Goku is caught off-guard when Cooler and his henchmen Doore (Masaharu Satô), Neiz (Masato Hirano) and Salza (Shô Hayami) land on Earth with the intention to kill him, and is badly wounded when he defends Gohan from a blast. Can Goku regain his strength and defeat Cooler before he destroys planet Earth and everyone he loves? In 'The Return of Cooler' (1992) Goku is horrified when he discovers that Cooler is back to invade New Namek and use the Namekians to power the Big Gete Star, his new ship. Goku, Gohan, Krillin, Piccolo (Toshio Furukawa), Oolong (Naoki Tatsuta), Yajirobe (Tanaka) and Master Roshi (Kôhei Miyauchi) arrive on New Namek and discover that the planet is being swarmed by massive silent robots and must find a way to defeat them...
