Porun, also called Pollun, serves as Prince of the Garden of Light. He debuted in *Futari wa Pretty Cure* and continued in *Futari wa Pretty Cure Max Heart*. Sent to Earth after the Prism Stones' restoration, he collided with Nagisa upon arrival, much like Mepple. During the first season, Wisdom empowered him with Prism Stone energy. This granted him sustained physical form and fleeting visions of the future, though the Pretty Cure team often needed to decipher his cryptic prophecies. He sapped his life force restoring the Rainbow Bracelets in the final clash against the Evil King, falling comatose until *Max Heart*.

Physically, he is a small white fairy with mint-green highlights, a furry neck, and a tail ending in an orb reminiscent of a spherical computer mouse. A small golden crown adorns his head, complemented by heart-shaped markings on his ears and forehead. Pointy highlights around his eyes complete his distinctive look.

Initially childish and selfish, Porun frequently annoyed others, especially Nagisa and Mepple, prioritizing his own whims. Despite his royal title, he behaved like an energetic young child obsessed with play. He matured over time, learning selflessness and demonstrating fierce loyalty to the Pretty Cure team, even charging into battles to aid them. His development shifted him from bratty antics toward responsibility and care.

Key relationships define his journey. In the first season, he lived mainly with Nagisa; their bond forged through friction as she found him irritating. Mepple resented him for disrupting his romance with Mipple, though later helped Porun grasp human concepts like Christmas. In *Max Heart*, his sister Lulun regarded him as her older brother, much to his frustration due to their inseparable past in the Garden. He resided with Hikari Kujou during *Max Heart*. Her unfailingly polite and gentle nature caused him anxiety; he mistook her lack of scolding for indifference. This relationship proved central, as Porun became Hikari's transformation device, the Touch Commune, enabling her to become Shiny Luminous.

Functionally, he transforms into the Pretty Commune (or Touch Commune in *Max Heart*), enabling open communication between the Garden of Light and Earth. He granted Nagisa and Honoka the Rainbow Bracelets, amplifying their powers with light energy. In battle, he enabled new attacks like Extreme Luminario and contributed to defenses, including protective barriers. His awakening alongside Hikari in *Max Heart* directly triggered her transformation into Shiny Luminous.

Notable trivia includes his habit of mangling "Pretty Cure" into "Purikura," a trait shared with Lulun that served to correct children's pronunciation. He holds the distinction of being the franchise's first mascot character to wear a head ornament (his crown) and to have a confirmed sibling relationship with another mascot.
