The Metal Heroes Series is a genre of tokusatsu superhero TV series produced by Toei for Japanese television.
The Metal Heroes are mainly space and police-based characters who don "metallic" suits, or are androids, or are cyborgs. Henceforth, most of the Metal Heroes are also referenced as "Henshin (transforming) Heroes." 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 1996 in conjunction with their other Tokusatsu superhero shows, such as Kamen Rider and Super Sentai. Not only are some of them popular in Japan but also in several other countries like France, Brazil, the Philippines, Malaysia, and Indonesia.
Some of the Metal Hero series even spawned sequels which followed the continuity of the previous shows, resulting in the genre developing sub-categories based mainly on space and police-related characters.
