Piyoko, formally titled Pyocola Analogue III, is an 8-year-old alien princess hailing from the destitute Planet Analogue. She leads the Black Gema Gema Gang, relentlessly pursuing her goal of kidnapping Dejiko for ransom to rescue her planet from financial ruin; this mission fuels her actions throughout the franchise. Born into the Analogue royal lineage, her mother is Pyocola Analogue II and her daughter becomes Pyocola Analogue IV. Her family includes an unnamed general father, stepfather Ryo Analogue, grandmother Pyocola Analogue I, and grandfather King Piyocolus Analogue. Three dedicated caretakers—Rik, Ky, and Coo—typically accompany her, serving as minions aiding her schemes. While these caretakers debuted in the Christmas Special, only the Gebas supported her initial appearance in the Summer Special 2000. Piyoko wields a signature attack, the Mouth Bazooka (or Upchuck Bazooka), firing a powerful laser from her mouth. Though comparable in strength to Dejiko's Laser Eye Beam, its longer activation time makes it less effective head-on. Her appearance features blonde hair, blue/teal eyes, and distinctive panda-themed accessories, including an original nurse-style hat with panda eyes and ears. In the spin-off *Panyo Panyo Di Gi Charat*, her attire shifts to a black maid dress with bat wings, retaining the panda ears, reflecting her recurring panda obsession. Her personality shifts across portrayals. Early depictions, particularly the Summer Special 2000, show malicious tendencies: destroying city blocks and creating a brainwashing store targeting Gamers and Dejiko's friends. Later portrayals soften her into a largely comedic antagonist, her schemes becoming harmless. She remains inherently good-natured yet easily deceived, often pushing herself too hard due to dedication to Planet Analogue. Development includes collaborative moments with Dejiko's group: celebrating Christmas after abandoning a kidnapping plot, participating in a joint Tsuyu Special play, and joining a Summer Vacation Special band. In *Panyo Panyo Di Gi Charat*, set earlier where she is 6, she works under Deji Devil. Here, her dynamic with Dejiko is less adversarial, with Dejiko's group treating her familiarly and affectionately as "Piyoko-chan." The OVA *Leave It to Piyoko!* adds backstory, showing her accidentally destroying part of Planet Analogue and fleeing to Earth with Rik, Ky, and Coo, further exploring their relationships and capture efforts. During the Flower Viewing Special, Piyoko's gang invades Dejiko's closet for shelter. They later share a peaceful cherry blossom picnic with Mr. Manager and her caretakers while Dejiko, Puchiko, and Rabi~en~Rose sleep, alongside a minor cursed trading cards scheme consistent with her persistent, non-threatening rivalry.
