Porun, also known as Pollun, is a fairy from the Garden of Light. Debuting in the latter half of *Futari wa Pretty Cure*’s first season, he holds the title of Prince of Light and stands as a guardian. His pivotal role includes bestowing the Rainbow Bracelets to the Pretty Cure team, unlocking their powerful Rainbow Storm attack. Initially residing with Nagisa, his mischievous and self-centered antics spark tension, frequently clashing with both Nagisa and Mepple.

In *Futari wa Pretty Cure Max Heart*, Porun relocates to live alongside Hikari and Lulun, the latter regarding him as an elder brother. Here, he gains new purpose as Hikari’s transformation catalyst, enabling her Shiny Luminous form. His dialogue, punctuated by the distinctive "-popo" suffix, contrasts with his playful rivalry with Lulun—teasing her relentlessly yet intermittently shielding her with unexpected protectiveness.

The film *Futari wa Pretty Cure Max Heart 2: Yukizora no Tomodachi* sees Porun journeying to snowy mountains with Hikari’s group. There, he bonds with Hinata, a newborn phoenix, and voices heartfelt concern over the creature’s isolation. Drawing parallels to his own bonds, he reveals a matured empathy, subtly showcasing his shift from egocentric tendencies to emotional depth.

Throughout the series and films, Porun’s journey intertwines lighthearted chaos with glimpses of vulnerability, particularly in his evolving rapport with Hikari and Lulun. While steadfast as a conduit for crucial transformations and attacks, his growth underscores a narrative thread weaving camaraderie and duty.
