Fourth Transformation

The standard Frieza Race progression moves from First Form through Second, Third, and finally the True Form, with each stage removing a layer of power suppression. Cooler discovered something different: a genuine transformation beyond the true form that added power rather than simply releasing what was already there. When Cooler confronted Goku on Earth seeking revenge for Frieza's defeat, he initially fought in his true form and found himself struggling against the Super Saiyan. Cooler then revealed his Fourth Transformation, a form he claimed Frieza had never known about, and the power gap immediately reversed.

Physical and Combat Changes

The Fourth Transformation dramatically alters the user's body. Cooler grew significantly taller, his musculature expanded, and his head developed an armored, crown-like carapace with a face mask that gave him a more predatory appearance. The form also enhanced his speed and durability to the point where Goku's Super Saiyan attacks, which had been effective moments earlier, became insufficient. Cooler dominated the fight until Goku pushed his Super Saiyan power to its maximum, eventually overpowering the Fourth Transformation with a point-blank Kamehameha that sent Cooler into the sun.

Other Potential Users

King Cold has long been speculated to possess a similar transformation. Given his enormous size and the implication that he was even more powerful than Frieza in certain continuities, it is possible that Cold, like his eldest son, had access to forms beyond the standard progression. In Super Dragon Ball Heroes, Frieza himself has been depicted using a Fourth Transformation in certain storylines, suggesting that the ability may be more widely available among powerful members of the race than Cooler initially believed. Meta-Cooler, the mechanical duplicate created by the Big Gete Star, could also access this form, combining its power with the regenerative capabilities of the machine network.

The Fourth Transformation holds significant importance in Dragon Ball's history because it was the first indication that the Frieza Race could evolve beyond the forms established during the Namek Saga. Before Cooler's Revenge, the True Form was understood to be the ceiling of the species' natural ability. Cooler's revelation that an additional stage existed expanded the lore of the Frieza Race and set the precedent for future transformations like Golden Frieza and Black Frieza.

From a narrative perspective, the Fourth Transformation also demonstrated that the Frieza family was not monolithic in its power. Each member had taken different paths: Frieza relied on raw innate talent and power suppression, while Cooler pushed his body into new evolutionary territory through deliberate effort. This contrast between the two brothers added depth to the Frieza Race as a species and suggested that their potential was far greater than any single member had fully explored.

Perhaps the most interesting application of the Fourth Transformation came through Meta-Cooler, the mechanical duplicate created when the Big Gete Star absorbed Cooler's remains. Each Meta-Cooler drone could access the Fourth Transformation, combining its biological power with the Big Gete Star's ability to repair, upgrade, and replicate itself. This meant that Goku and Vegeta were not fighting one opponent in the Fourth Transformation but potentially hundreds, each one capable of adapting to and countering whatever strategy the Saiyans employed. The Fourth Transformation became a template for mass production rather than a unique achievement.

Video Game Prominence

Across Dragon Ball video games, the Fourth Transformation has become one of Cooler's defining characteristics, distinguishing him from Frieza in roster selections. Games like Budokai Tenkaichi, Xenoverse, and Dragon Ball FighterZ feature the form as Cooler's primary combat state, often treating it as his equivalent of Frieza's True Form rather than as an additional stage beyond it. This game portrayal has cemented the Fourth Transformation as an iconic part of Dragon Ball's visual language, immediately recognizable by its armored head carapace and face mask design. The form's popularity in games has also contributed to Cooler remaining a fan-favorite character despite being limited to films and non-canonical media for most of the franchise's history.
