The character widely known as Honkan or Honkan-san bears the official name Mentama Tsunagari Omawari-san, meaning "The Police Officer with the Connected Eyes." This name highlights his defining physical feature: wide eyes that seem fused into a single continuous eyeball. Other notable traits include a single centered nostril in an upturned nose, a prominent underbite, and buck teeth. He typically wears a standard police uniform with his hair styled like a sprout, though his hairstyle and attire vary during off-duty moments or non-police roles.

He possesses a volatile, short-tempered personality, frequently firing his gun into the air to declare arrests or issue threats, including the death penalty. These outbursts occur not only over crimes but also minor annoyances, disruptions to meals—especially ramen—or perceived slights. Persistent obsessions with career advancement and financial gain remain perpetually unfulfilled. Gluttony and overt lust, primarily towards attractive women, are recurring themes. His sexuality and gender expression shift fluidly across stories; while often heterosexual, narratives sometimes depict closeted homosexuality, cross-dressing, or gender dysphoria. Extreme frustration once led to self-emasculation, resulting in effeminate behavior. His relationships with children, including his own sons, are hostile and neglectful. Multiple sons appear across narratives, often resembling him physically, such as Isamu and Demeo. Isamu's deception about stomach pain led to a doctor's mutilation and his eventual death from a real illness ignored due to prior false claims. Another storyline featured numerous miniature sons from a "mouse bride" whom he manipulated and ultimately cannibalized. He killed Demeo to frame a criminal after using him as bait in a kidnapping scheme.

Interactions frequently involve conflict. Bakabon’s Papa enjoys pranking him, sometimes causing severe humiliation, maiming, or driving him to temporary suicide. Their adversarial relationship began in childhood when he was a frequent target of Papa’s mockery. Encounters with the thief Kaoru-chan sometimes culminate in romantic entanglements. His professional background varies: origins include serving as a neighborhood’s private officer motivated by a fondness for gunfire, working within larger police structures, or holding prior occupations like hunting. Periodic firings for misconduct or incompetence are common, though reinstatement frequently follows. Moments of professional integrity and loyalty occasionally surface, yet his overarching characterization remains comically inept and morally ambiguous.

He appears extensively across Fujio Akatsuka’s works through the "Star System," featuring in *The Genius Bakabon*, *Extraordinary Ataro*, *Osomatsu-kun*, *The Chicken Family*, *Let’s La Gon*, *Boy Friday*, *Waru Waru World*, and numerous other titles. His roles adapt to individual story needs, leading to inconsistencies in familial relationships, backstory, gender identity, or sexuality. Core traits—his appearance, temper, firearm misuse, and flawed persona—remain consistent anchors.
