Horrorman recurs throughout the *Anpanman* franchise. Visually, he is a skeleton wearing a long, tattered purple shirt emblazoned with a crossed bones emblem on the chest, featuring protruding kneecaps and cheekbones, and a permanently visible set of teeth. Despite his frightening appearance, his personality is happy-go-lucky, clumsy, and easily manipulated. He delights in attempting to scare others, though intentional success is rare; unintentional scares happen more often due to his inherent goofiness. While fundamentally kind, he often shows insensitivity toward others' feelings.

He harbors a significant, unrequited obsession with Dokeen, persistently gathering flowers and food in futile attempts to win her favor. His primary ability involves detaching the crossed bones emblem from his shirt to use as boomerang weapons.

His franchise debut was in the *"tobe Anpanman"* comics. His animated introduction came in the 1991 movie *Soreike! Anpanman Tobe Tobe Chibigon*, where he mentored Chibigon, leading to his recurring role in the television series. His backstory beyond this mentor role is largely undefined; a 2007 film short ambiguously suggested a possible past as a prince. Within the film *Soreike! Anpanman: Yomigaere Bananajima*, Horrorman appears among the characters journeying to Banana Island.

The character experienced two voice actor changes, prompted by the original actor's passing and subsequent health issues affecting his replacement. His arc primarily involves occasional alliances with antagonists Baikinman and Dokeen, frequently marked by reluctance to fully engage in their schemes. His persistent but unsuccessful courtship of Dokeen, his attempts at scaring others, and his general clumsiness form the core of his recurring comedic traits.
