cooler

Cooler (クウラ, Kūra) is the eldest son of King Cold and Frieza's older brother. The boss of the Cooler Force division, he is just as cruel as the rest of his family and was the first known member of his family to discover a transformation beyond his race's true form. Cooler is the titular main antagonist in Dragon Ball Z: Cooler's Revenge. An emulation of him known as Cooler's appearance in his base form is similar to that of Frieza's Final Form, though Cooler's skin is deep purple as opposed to the pure white of his brother. Cooler is also much taller than Frieza, being similar in height to Goku. Along with this, Cooler has a distinctively more masculine appearance than that of Frieza, who is leaner built (excluding the engorged muscle mass when at 100% full power). Cooler also sports several armor-like carapaces on his chest, shoulders, shins, and head; these are apparently natural given how they too change when he transforms.
