''Metal Heroes'' is a franchise of Japanese live-action Action/Adventure programs produced by Toei.

The series aired from 1982 (with ''Series/SpaceSheriffGavan'') to 1998 (with ''Series/TetsuwanTanteiRobotack''), but was revived in 2012 for a crossover with ''Series/KaizokuSentaiGokaiger'' and the popularity of the film resulted in a standalone movie. They are {{toku}}satsu-based shows, in the same vein as ''Franchise/KamenRider'' and ''Franchise/SuperSentai''.

In the US, footage from these series was adapted by Saban during the late-1990's in the same way they did with ''Super Sentai'' for ''Franchise/PowerRangers'', producing two shows, ''Series/VRTroopers'' (1994-1995) and ''[[Series/{{Beetleborgs}} Big Bad Beetleborgs]]'' (1996-1997). The programs are popular in Japan, France, Brazil and Southeast Asia. It also gave us the wonderful acid trip ''Uchuu Keiji Shaider''. Compared to even ''Franchise/KamenRider'', it was perhaps the darkest franchise of all {{toku}}satsu shows in general and more adults liked it than the kids.

The NES game ''VideoGame/{{Shatterhand}}'' was produced by Japanese company Natsume and released for both the NES and Famicom. Unlike in most instances, the American version ''Shatterhand'' was actually the original version of the game (although it was released later). Angel (a subsidiary of Bandai) agreed to publish the game in Japan for Natsume under the condition that they could modify it into a licensed game promoting one of their properties. Thus the game was re-worked to function as a ''Series/TokkyuuShireiSolbrain'' video game.

* ''Series/SpaceSheriffGavan'' (1982-1983)

It should be noted that there are a few distinct trilogies within the franchise:
* The first three shows (''Gavan'', ''Sharivan'', and ''Shaider'') form the ''Space Sheriff'' trilogy (''Uchuu Keiji'' in Japanese).
* ''Winspector'', ''Solbrain'', and ''Exceedraft'' form the ''Rescue Mission'' trilogy.

Other continuations include:
* ''Series/JuukouBFighter'' and ''Series/BFighterKabuto'' are a continuation from one another as the ''Beetle Fighter'' series.
* ''Series/BRoboKabutack'' and ''Series/TetsuwanTanteiRobotack'' are also considered sharing the same universe, having a crossover of the two while having similar themes.
* A crossover episode also denotes that ''Jiban'' and ''Jiraya'' also share the same universe, despite having distinct themes.
* Finally, the ending of ''Gavan vs Dekaranger'' depicts a random pick of past Sentai and ''nearly all the other Metal Heroes'' as a MCU-style SharedUniverse.

!!Tropes commonly associated with ''Metal Heroes''
* CoolBike: Yep!
* CoolCar: If they don't have a bike, they will have an awesome car. [[Series/ChoujinkiMetalder Some]][[Series/KidouKeijiJiban times]] both, actually.
* CoolSidecar: The Cool Bike often has one of these even when there is only one hero. Sometimes the sidecar can be deployed to attack on its own, or sometimes the VictimOfTheWeek occupies it while the hero delivers him or her to safety.
* CrossOver: Several series will have someone from one or more past series return, though it wasn't a staple like Sentai's Vs. movies. Also, lately, the ''Franchise/SuperSentai'' series likes to team up with ''Series/SpaceSheriffGavan'' and ''Series/SekaiNinjaSenJiraiya''.
* HenshinHero: With the exception of both Jiraiya and Blue SWAT who put on their armor manually and Janperson who is a robot without a human form.
* PoweredArmor: If they're not {{Cyborg}} or RidiculouslyHumanRobot, they're human beings wearing a special suit of armor.
* ShoutOut / NamedAfterSomebodyFamous: Early shows had a tendency to name their protagonists after film personalities:
** [[Series/SpaceSheriffShaider Shaider]] after American actor Roy Scheider
** [[Series/SpaceSheriffGavan Gavan]] after French actor Jean Gabin
** [[Series/JikuuSenshiSpielban Spielban]], after American filmmaker Creator/StevenSpielberg
** One of the names considered for [[Series/KyojuuTokusouJuspion Juspion]], in an early stage of pre-production, was [[Creator/RobertDeNiro Deniro]]. Unfortunately, [[WhatCouldHaveBeen it wasn't carried to the show]].
** In ''[[Series/TokusouRoboJanperson Janperson]]'', supporting character Gun Gibson was named after MelGibson, apparently. This doesn't apply to the protagonist, however, whose name [[SomethingPerson comes from him wearing a jumper]].
* TransformingMecha: Even though these series don't often go in for MakeMyMonsterGrow, the flying fortress can often turn into a robot and/or a cannon to deal with the enemy's {{Mook}}-piloted air force.
