Special Rescue Exceedraft

The protagonists of the Metal Hero Series are mainly space, military and police-based characters who are typically either androids, cyborgs, or humans wearing metallic armored suits. Henceforth, most of the Metal Heroes are also referenced as another example of the "Henshin (transforming) Heroes" genre. Usually, the genre revolves around a technological theme where technology, in the right hands, can be used for the greater good.

The shows were produced by Toei from 1982 through 1999 in conjunction with their other Tokusatsu superhero shows, Kamen Rider and Super Sentai. Initially only the series released between 1985 and 1989 (Juspion, Spielban, Metalder, Jiraiya and Jiban) were considered part of the Metal Hero franchise while Gavan, Sharivan and Shaider were part of the Space Sheriff franchise and Winspector, Solbrain and Exceedraft were part of the Rescue Police franchise. It was only in late-1990s that Toei Company incorporated the Space Sheriff and Rescue Police trilogies as subseries of the Metal Hero. Blue SWAT, Janperson, B-Fighter, B-Fighter Kabuto, Kabutack and Robotack were also incorporated into the franchise afterwards.

In addition to Japan, they are also popular in France, Brazil, the Philippines, Thailand, Malaysia and Indonesia. During the 1990s, Saban Entertainment used some of the shows to produce programs similar to their Power Rangers series. Some of the Metal Hero Series even spawned such sequels which followed the continuity of the previous shows, resulting in the genre developing sub-categories based mainly on space, military and police-related characters.
