Cooler (クウラ, Kūra; lit. "Coola") is the main villain in the movies Dragon Ball Z: Cooler's Revenge and Dragon Ball Z: The Return of Cooler. He is the older brother of Frieza, and the eldest son of King Cold. Much like his brother, he can push his body through transformations to increase his power. Although only two forms are seen (the last two), it is stated in the fifth film that Cooler possesses the same number of forms Frieza does, as well as a fifth and more powerful form, which he uses to combat Goku. Also like his brother, Cooler gains a bio mechanical final form, but is gained from merging with the Big Gete Star.
