Collection of two Japanese anime movies from the Dragonball Z series. In 'Cooler's Revenge' (1991) the recently-slain Frieza (voice of Ryûsei Nakao)'s brother Cooler (Nakao) hears of his brother's death and must have his vengeance to protect his family's honour. Goku (Masako Nozawa) 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 (Nozawa) 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 (Nozawa) is horrified when he discovers that Cooler (Nakao) is back to invade New Namek and use the Namekians to power the Big Gete Star, his new ship. Goku, Gohan (Nozawa), Krillin (Mayumi Tanaka), 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 and save the Namekians, which proves to be a difficult task.
