The term refers to a specific action figure release within a popular toy line, depicting a character with ties to supernatural themes, often associated with Halloween or similar autumnal celebrations. These figures are sought after by collectors due to their limited availability and unique character design.
This series represents an opportunity for collectors to acquire figures of lesser-known, yet interesting, characters from the comic book universe. The inherent collectability and limited nature of production often drive up the value in the secondary market. The release also allows fans to celebrate a specific holiday season through their hobby.
