"Robot Investigator Janperson") is a Japanese television show and 1993 installment in Toei Company's Metal Hero Series franchise.

[1] The series revolves around Janperson, a robotic detective who patrols the streets of Tokyo and fights against three different underworld organizations that use super technology to subjugate the masses.

Unlike most Metal Heroes, a monster-of-the-week is rarely shown and most of the villains are criminals akin to television police dramas.

The Guild (ギルド, Girudo) was an evil organization of cyborgs whose goal was to eradicate and replace all humanity.

Janperson, Gun Gibson, and Bill Goldy made brief cameos in the "Convention Dimension" episode of Big Bad Beetleborgs as Karato, Silver Ray, and Goldex, respectively.
