Abarenbou is a chaotic, water-like creature known for his rowdy and unpredictable nature. His physical form typically appears mostly naked, with humor often centering on his exposed buttocks through shaking or flatulence; adaptations for younger audiences, like *Di Gi Charat Nyo!*, modify this by adding clothing. His personality embodies extreme randomness and disruptive antics. Under the alias "Paya-paya" in the *Summer Special 2000*, he reveals a malicious side, attempting to destroy the Gamers store to rebuild it, demonstrating a willingness to use perceived wealth for destructive ends, often invoking *Screw the Rules, I Have Money!* tropes. His background lacks clear definition, though indirect hints suggest a possible familial connection to a character named "Bon" (who resembles Piyoko). Piyoko denies recognizing him, leaving their relationship ambiguous. Abarenbou consistently serves a comedic and antagonistic role across media: causing trouble at Gamers in the original series (Episode 14: "Abarenbou Comes to Town"); brainwashing customers and orchestrating Gamers' destruction as "Paya-paya" in the *Summer Special 2000* (Episode 3: "The Return of Abarenbou"); transforming into a giant broccoli monster during the *Christmas Special*'s *Behemoth Battle*; and participating in a collaborative play performance with other characters in the *Tsuyu Special*, indicating occasional non-antagonistic interaction. Ironically, while his name "Abarenbou" translates to "a man who goes on a rampage," no canonical depictions show him actively rampaging.
