Dragon Ball Z: The Return of Cooler is the sixth movie in the Dragon Ball Z franchise. The movie begins with the peaceful Namekians living on New Namek, where they are suddenly threatened by a powerful force. Cooler, the brother of Frieza and a former enemy of Goku and the Z Warriors, has been resurrected as a powerful robot and has enslaved the Namekians.
Goku and his friends, including Piccolo, Krillin, Gohan, and Vegeta, arrive on New Namek and discover the horrors that Cooler has unleashed on the normally peaceful planet. They realize that they must stop Cooler's evil plan and free the Namekians from his control.
The Z Warriors engage in a fierce battle with Cooler and his mechanical army. The battle takes them to various locations on the planet, including a giant machine that Cooler uses to absorb the energy of New Namek's star. Goku and his friends must use all their skills and powers to defeat Cooler and his minions and protect the Namekians.
As the battle heats up, Goku and Vegeta fuse together to become the mighty warrior, Vegetto. Their combined strength is enough to defeat Cooler and his robotic army once and for all, freeing New Namek from his tyranny.
In the end, Cooler's defeat ensures peace for New Namek and its inhabitants. The Z Warriors leave the planet, knowing that they have once again saved the galaxy from destruction.
