Description
Unagi-Inu, meaning "Eel-Dog," is a hybrid creature originating from Fujio Akatsuka's works, first appearing in *The Genius Bakabon* manga. His creation occurred during a heatstroke-affected idea meeting at Fujio Pro, sparked by either an editor's suggestion about a hallucinating police officer mistaking a dog for an eel or Akatsuka directly observing a dog that resembled an eel, resulting in the concept of a creature combining both animals.
Physically, Unagi-Inu has a long, slender eel-like body with a tail and fins, paired with a dog's head and legs. His typical coloration is black with a white underbelly, large pink lips, and white or blue tail fins. Due to concerns about visual misinterpretation, some merchandise alters his color scheme, and the 1975 anime adaptation depicted him as bright blue for technical and visibility reasons.
His personality is marked by politeness and a laid-back demeanor; he often uses honorifics in speech and ends sentences with barks ("wan wan!"). His eel half makes him highly desirable as food, particularly to the Police Officer with the Connected Eyes, forcing him to frequently evade capture and consumption. In later adaptations like *Late Night! Genius Bakabon*, he adopts a more observational, "tsukkomi" (straight man) role, commenting on surrounding events.
Unagi-Inu's family background is detailed across media. His mother was an ordinary eel living in a specialized aquatic section of their home; by *Late Night!*, she had been deceased for 17 years, with posthumous revelations of infidelity with other animals. His father was an ordinary dog who had an affair with a "Dog of Night," resulting in additional siblings. Documented family includes an older sister, Unagi-Inue (a cosmetics saleswoman married to a frog, with whom she has a daughter), and a younger sister, Unagi-Inuko (a nurse). A white variant of his species appeared in the *Rerere* anime and pachinko games. In *Late Night!*, he is revealed to have a daughter who expresses a desire to marry a human man, though her mother's identity remains unconfirmed. A non-canonical gag in *Let's La Gon* depicts a son, Inu-Unagi, with reversed physical traits (dog body, eel head).
His narrative role evolved significantly from his debut. Initially a speechless one-off character grilled and eaten in a manga chapter, unexpected popularity prompted Akatsuka to reintroduce him. Subsequent appearances established his awareness of being a consumption target and his efforts to avoid it, while also serving as a neighborhood advisor or fleeing dangers. In *Late Night!*, his character arc includes attending a family memorial service and confronting revelations about his mother's infidelity, alongside his daughter's storyline.
Beyond the core *Bakabon* series, Unagi-Inu appeared in numerous other Akatsuka works like *Osomatsu-kun*, *Wanpei and Mo-chan*, and *Let's La Gon*, often in cameo or background roles. His animated appearances span multiple *Bakabon* adaptations: he debuted in the 1975 *Original Genius Bakabon* anime (with a modified story where he survived being cooked), followed by background roles in *Heisei Genius Bakabon* and *Rerere's Genius Bakabon*. In *Late Night!*, he features more prominently, including a focus on his family dynamics.
