Collection of two Japanese anime features from the 'Dragonball Z' series. 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's taken root, the Tree of Might will devour all life energy, leaving the planet a deserted land where no living thing can survive. Goku (voice of Masako Nozawa) 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 (Nozawa) 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 (Kenji 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.
