The is a metaseries of tokusatsu superhero TV series produced by Toei for Japanese television.

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.

International adaptations United States During the 1990s, Saban adapted Metal Hero Series shows for American audiences; stock footage from Metalder, Spielvan and Shaider was used in VR Troopers (1994–1996), and footage from both B-Fighter series was later used in Big Bad Beetleborgs. Both shows ran for two seasons. As of 2018, Discotek Media has licensed Juspion for release marking the first release of the Metal Heroes in the US. Both Jiraiya and Gavan were used for the Power Rangers franchise with Jiraiya as Sheriff Skyfire in Power Rangers Super Ninja Steel and Gavan as Captain Chaku in Power Rangers Beast Morphers.

Philippines Zaido: Pulis Pangkalawakan was greenlighted by Toei as a sequel to Shaider, with characters who are descendants of those in the original series. Toei later halted production, instead authorizing a spin-off series set 20 years after the end of Shaider.

Current status Other similar heroes, such as Nebula Mask Machine Man, Kyodai Ken Byclosser, Lady Battle Cop, and Choukou Senshi Changéríon, were also produced during the time that the Metal Hero Series were on the air, but are not included as part of the Metal Hero Series for various reasons. Machine Man and Bicrosser were created by Shotaro Ishinomori, while Changéríon's armor is not metallic and aired on TV Tokyo. It is unknown if Lady Battle Cop is part of Toei's shared universe.

The Metal Hero Series was discontinued in 1999, as the company rather favors the Super Sentai and Kamen Rider Series of shows, allegedly due to the passing of Shotaro Ishinomori. However, many of the traits of the series have been adopted into the newer installations of the Super Sentai and Kamen Rider shows. Today, the present versions of this type of heroes are also merged in with the Henshin Heroes description.

Some Metal Heroes have also made cameo appearances. In 2004, a special Tokusou Sentai Dekaranger stage show had a special appearance by Gavan, who assisted Hurricane Red from Ninpuu Sentai Hurricaneger and Aba Red from Bakuryuu Sentai Abaranger in battling various Alienizer monsters from Deka Ranger.

In 2005, Toei released some Uchuu Keiji trilogy merchandise. Later that year, Bandai released a "Souchaku Henshin" figure of Gavan, followed by "Souchaku Henshin" figures of Sharivan and Shaider in early 2006. In May 2006, a PlayStation 2 video game titled The Space Sheriff Spirits was released. The game featured Gavan, Sharivan and Shaider all teaming up to battle past enemies from their series. In early 2008, the trading card company Cardass announced a new, Metal Heroes based expansion to their Rangers Strike card game, entitled Special Metal Edition, featuring characters and vehicles from the various Metal Hero Series for use within the game.

Space Sheriff Series re-emerged in the 2010s with feature films, including new actors portraying successors to Gavan, Sharivan, and Shaider. Some of them are stand alone entries, while others feature crossovers with other Super Sentai and Kamen Rider characters. As a part of Toei's Project R.E.D., the series will mark a return in 2026 with Super Space Sheriff Gavan Infinity, a new television series drawing heavy inspiration from the original Space Sheriff trilogy.
