Character: cooler (dragon ball)
Coolerクウラ Kūra, lit. "Coora") iis the titular main antagonist in the movie Dragon Ball Z: Cooler's Revenge and an emulation of him acts as the main antagonist in its sequel 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. This form is known as Meta-Cooler
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 more lean-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.
When he transforms to his true form, however, his body undergoes great changes as opposed to his base form: his chest and muscle-mass have expanded greatly, to a degree similar to that of Frieza's Second Form. His white carapace also changes, with the breast-plates shoulder pads becoming hoop-like in shape, becoming something like white "handles", while the white carapaces on his wrists change drastically, gaining dark-blue sections and developing blade-like protrusions. The tip of his tail gains a white pointed stinger-like carapace as well. However, the most distinguishing characteristic in this form is, perhaps, the change in the carapace Cooler has on his head, which in this form completely encases his entire head except for his eyes, his mouth being covered behind something reminiscent of a visor, four spikes extend from his cranium and there is a large dark-blue section in the middle of his head.
