Cooler's appearance in her 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 her brother. Cooler is also much taller than Frieza, being similar in height to Goku. Along with this, Cooler has a distinctively more muscular 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 her chest, shoulders, shins, and head; these are apparently natural given how they too change when she transforms. In her Final Form, Cooler adopts a dramatically more fearsome and powerful appearance than in her previous states. Standing even taller than in her base form, she exudes a commanding and menacing presence. Her physique becomes sleeker but more muscular, emphasizing both power and agility. Her body, covered in bio-armor, gleams with a glossy, nearly metallic sheen—primarily white with purplish-blue bio-gems adorning various parts of her body.

Her facial features become sharper and more intimidating. Her face is mostly covered by a natural mask-like helmet that extends backward into a crown of long, curved, and blade-like protrusions, almost resembling a spiked crest. This organic crown is reminiscent of Frieza's final form, but more elaborate, giving her a regal yet alien appearance. Beneath the mask, only her piercing red eyes and parts of her mouth are visible, adding to her mysterious and threatening aura.

She has no visible nose, and her mouth is filled with sharp, predatory teeth that she bares when smiling or snarling. The armored plating on her shoulders forms pointed pauldrons that give her an even broader, more intimidating silhouette. Her arms and legs are lean yet powerfully built, with the same smooth white armor coating them. The purple gem-like orbs on her body—one on each forearm, chest, and knees—glow subtly with power, adding a mystical quality to her already alien form.

Her tail is long and muscular, covered in the same bio-armor as the rest of her body, and tipped with a blunt, club-like end—useful for both balance and as a weapon. Her fingers are clawed, capable of slicing through rock and steel, and her movements are fluid and deliberate, underscoring her confidence in this perfected transformation.

Overall, in her Final Form, Cooler radiates a sense of superiority and controlled brutality—sleek, powerful, and precise. She is a predator evolved to perfection, with a form that reflects not only her raw might but also her tactical intelligence and terrifying presence. Cooler's personality is quite similar to that of his younger brother and his father, though with a few noticeable differences. Like Frieza, Cooler handles problems in an intellectual and serious manner. Though, unlike his brother, Cooler is not as consumed by his ego and is less likely to underestimate his opponents, as seen when he acknowledged that Goku was still alive despite taking a direct hit from his Darkness Eye Beam, due to the latter managing to utilize a counterattack against him, and thus ordered his subordinates to search for and kill him, and in the English dub also deliberately refuses to use the easy solution of ensuring Goku's death by blowing up the Earth specifically in order to make sure he had confirmed Goku's death with his own eyes despite his preference of blowing it up. Even when they had demolished a large portion of the surrounding environment with continuous barrages of energy blasts, he insisted that they continue their pursuit. Likewise, he does not get overly proud of accomplishments that require little effort as he found Frieza's gloating at destroying Planet Vegeta so childish. This is also implied by his admission that he and his forces deliberately target planets that are considered more difficult to conquer in contrast to his brother. Cooler is also apparently more positively inclined and respectful towards his subordinates than his brother and father, as he has never once been seen abusing, ridiculing, executing them or anything of the sort. He also offers to take on opponents who outmatch them personally, which likely contributes to their undivided loyalty and respect for him. He even seems to be inclined to take his subordinates' advice. However, Cooler still underestimated his opponent, as by allowing Goku's space pod to escape instead of following his subordinates' suggestion of shooting it down, he was paving his own downfall years later when Goku defeated him. Cooler himself lamented that when he looked down on Frieza for being soft that day, he himself was no better for not shooting down Goku's pod. In Super Dragon Ball Heroes: World Mission, it is revealed that Cooler cares for his nephew Kuriza and allows him to fight alongside him against the Dragon Ball Heroes, Beat and Note. However, it should be noted that their interaction occurs within an anomalous extra dimensional space within Age 764 of the game world timeline thus it is unclear if the nature of their relationship was altered by the game world anomaly responsible for the alterations to the history of Age 764 that resulted in Kuriza and later his uncle coming to the aid of Mecha Frieza and King Cold in the first place.
