Frozen serves as a primary antagonist in *Futari wa Pretty Cure Max Heart 2: Yukizora no Tomodachi*, hailing from the Dotsuku Zone as a loyal subordinate to the Evil King. Alongside his partner Freezen, he forms an ice-based duo proclaiming themselves the "strongest combination." Both harbor intense hatred for warmth and relentlessly pursue the destruction of the phoenix Hinata, whose heat sustains the world. Frozen sports lighter blue skin adorned with turquoise facial markings, contrasting with Freezen's darker hue. His design features messy blue hair and asymmetrical spiked armor, with spikes protruding from his left shoulder and right wrist.

Commanding formidable ice-manipulation powers, Frozen collaborates with Freezen to unleash "Freezing Blizzard," a joint assault capable of flash-freezing vast landscapes like the Garden of Clouds. His cold-hearted and treacherous personality mirrors Freezen's, marked by fierce pride in their partnership. He revels in shattering the bonds of other duos, demonstrated when he implants ice crystals into Cure White's heart, compelling her to battle Cure Black against her will. This tactic showcases his penchant for exploiting emotional weaknesses to dismantle teamwork.

Confronted with failure, Frozen habitually shifts blame onto Freezen, exposing cracks in their vaunted alliance. Following their initial defeat—where Hinata empowers the Pretty Cures to achieve a Phoenix form and shatter them—Frozen resurfaces in the crossover *Pretty Cure All Stars DX 3: Mirai ni Todoke! Sekai wo Tsunagu☆Niji-Iro no Hana*. Revived by the entity Black Hole alongside other villains, he and Freezen clash with Cure Melody and Cure Rhythm amid a ship graveyard. Their final defeat comes via the duo's "Passionato Harmony" attack, standing among the rare instances where villains fall to Cures outside their original narrative.
