Cooler is the titular main antagonist in the movie Dragon Ball Z: Cooler's Revenge and an emulation of him acts as the main antagonist in Dragon Ball Z: The Return of Cooler. He is the older brother of Frieza and the elder son of King Cold. Like his brother, he can push his body through transformations. Also, like Frieza, Cooler possesses a biomechanical incarnation, but this is gained from merging with the Big Gete Star.
