What Is the Metal Hero Series? A Beginner's Guide
"What is Metal Heroes" is one of the most-asked questions in the tokusatsu fandom. Here's the franchise Kamen Rider and Super Sentai fans keep pointing newcomers toward.
If you're deep into Kamen Rider or Super Sentai and keep seeing "Metal Heroes" mentioned as toku's third major pillar, you're not alone in wondering what it actually is — "What is Metal Heroes" is a recurring, genuinely common question in tokusatsu communities.
The basics
Metal Hero is a Toei tokusatsu franchise that ran on Japanese television from 1982 to 1999 (and continues in specials and revivals since), produced alongside Kamen Rider and Super Sentai as one of Toei's three major superhero lines. Unlike Sentai's team format, Metal Hero seasons are usually built around a single central hero — often a space police officer, detective, or law-enforcement figure — wearing an armored, metallic-finish suit rather than the cloth-and-rubber suit design common elsewhere in tokusatsu.
What actually makes it "Metal Hero"
The name comes from the suit design philosophy: a heavily armored, metal-plated look rather than the sleeker insect/animal-inspired designs common to Kamen Rider, or the color-coded team uniforms of Super Sentai. Metal Hero protagonists frequently operate within a sci-fi law-enforcement or space-policing framework — Space Sheriff Gavan (1982), the franchise's starting point, set the template of an armored space cop fighting crime across a galactic beat.
How it's different from Kamen Rider specifically
Both are frequently single-hero-led shows, which is exactly why newcomers mix them up. The clearest distinctions: Metal Hero suits lean into visible metallic armor plating and a law-enforcement/sci-fi premise, while Kamen Rider suits lean into insect, animal, or thematic-gimmick design with roots in a monster-transformation premise rather than a police one.

Where the franchise stands now
Metal Hero's legacy is getting a direct spotlight again: Toei's new Project R.E.D. banner revives 1982's Gavan as Super Space Sheriff Gavan Infinity, taking over Super Sentai's Sunday morning TV Asahi slot once that franchise concludes in 2026 — effectively passing the baton from the ensemble Sentai format back to the single-hero Metal Hero tradition that predates it.
