The Metal Hero Series (メタルヒーローシリーズ, Metaru Hīrō Shirīzu) is a metaseries of tokusatsu superhero TV series produced by Toei.[1]

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.

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.

History

[edit]

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 Heroes 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. Janperson, Blue SWAT, B-Fighter, B-Fighter Kabuto, Kabutack and Robotack were also incorporated into the franchise afterwards.

On November 23, 2025, Toei announced that a new brand called Project R.E.D. (Records of Extraordinary Dimensions), which would take over the Sunday 9:30 AM timeslot.[2] The first show under this project is Super Space Sheriff Gavan: Infinity.[3]

[edit]

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 Type-G as Captain Chaku in Power Rangers Beast Morphers.

Philippines

[edit]

Zaido: Pulis Pangkalawakan was greenlighted by Toei as a sequel to Shaider, with characters who are descendants of those in the original series.[5] Toei later halted production, instead authorizing a spin-off series set 20 years after the end of Shaider.[6]

Current status

[edit]

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 Byclosser were created by Shotaro Ishinomori, while Changéríon aired on TV Tokyo. It is unknown if Lady Battle Cop is part of Toei's shared universe.

Currently, the Metal Hero Series is one of Toei's defunct properties, 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 Dekaranger.

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.

Despite no more television series having been made, the 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.

On November 18, 2025, an official Japanese trademark filing for Super Space Sheriff Gavan Infinity was reported.[7]

View on Grokipedia
from Grokipedia
The Metal Hero Series (メタルヒーローシリーズ, Metaru Hīrō Shirīzu) is a Japanese tokusatsu franchise produced by , comprising 17 television series that aired on from March 5, 1982, to January 24, 1999, featuring armored superheroes with metallic suits who combat threats ranging from interstellar criminals and alien invaders to monstrous villains and earthly foes. Initiated with Uchū Keiji Gavan, the series emerged during the hiatus of Kamen Rider in the early 1980s, establishing a distinct pillar alongside Super Sentai in the company's tokusatsu lineup by emphasizing sci-fi elements, high-tech weaponry, and mecha transformations over team-based dynamics. The franchise evolved across three informal eras: the "Space Sheriff" trilogy (Gavan, Sharivan, and Shaider from 1982–1985), focusing on interstellar law enforcement; the mid-1980s "cosmic warrior" phase with titles like Kyojuu Tokusou Jaspion and Choujinki Metalder (1987–1988), blending fantasy and adventure; and the 1990s shift toward police procedurals and bio-armored heroes in series such as Tokkei Winspector, B-Robo Kabutack, and Tetsuwan Tantei Robotack. Each entry typically ran for 30–50 episodes, incorporating practical effects, suitmation, and explosive action sequences characteristic of tokusatsu, while promoting themes of justice, technology, and heroism. Beyond its original run, the Metal Hero Series has maintained a lasting legacy through home video releases, merchandise, and crossovers, notably appearing in the Super Sentai film Kaizoku Sentai Gokaiger vs. Uchū Keiji Gavan: The Movie (2012) to mark the franchise's 30th anniversary. Toei continues to celebrate the series officially, including the launch of a dedicated Twitter account (@metalH_official) in 2022 for its 40th anniversary and ongoing streaming availability via the Toei Tokusatsu Fan Club app, underscoring its enduring appeal in Japanese pop culture despite the absence of new productions since 1999.

Overview

Franchise Concept

The Metal Hero Series is a Japanese tokusatsu superhero franchise produced by , consisting of television series that feature protagonists clad in metallic armored suits who combat villains including aliens, criminals, and monsters. These heroes, often portrayed as space enforcers, cyborgs, or enhanced humans, embody a blend of and action elements central to the genre. At its core, the franchise explores themes of , , and heroism, with characters relying on advanced gadgets, transforming vehicles, and suit-based powers to uphold order against interstellar threats or earthly crimes. This emphasis on high-tech weaponry and moral resolve distinguishes the series within Toei's portfolio, positioning it alongside established lines like and as a key pillar of the company's output. The series debuted in 1982 with , which introduced the foundational concept of a lone galactic lawman in a chrome suit battling cosmic invaders, and it has since evolved in hero designs from space sheriff archetypes to more varied forms like robotic constructs and specialized police squads, all unified by the iconic metal armor motif. Examples such as Juspion highlight this progression into broader narratives while maintaining the technological heroism at the forefront.

Historical Development

The Metal Hero Series originated in 1982 as Toei Company's effort to launch a new line of programming centered on individual armored heroes, diverging from the team-oriented format of the ongoing franchise, and drawing inspiration from contemporary narratives and trends prevalent in Japanese media. This initiative began with , which introduced a solo protagonist in a metallic suit combating interstellar threats, marking Toei's strategic expansion into single-hero stories to complement their established ensemble series. The franchise achieved its peak popularity during the 1980s through the Space Sheriff trilogy—comprising Gavan (1982), Sharivan (1983), and Shaider (1984)—which captivated audiences with high-stakes cosmic adventures and innovative suit designs, solidifying the Metal Hero aesthetic of durable, metallic armor. Building on this success, Toei diversified the series into fantasy elements with Kyojuu Tokusou Jaspion in 1985, blending mythological quests with sci-fi action, and later shifted toward police procedural themes in the early 1990s, as seen in Special Rescue Police Winspector (1990), which emphasized team dynamics within law enforcement scenarios while retaining the core metallic hero motif. Spanning from 1982 to 1999, the production run encompassed 17 main television series, collectively producing over 800 episodes that explored varied genres from interstellar policing to bio-beast investigations. The franchise concluded its original run in 1999 amid shifting audience preferences favoring the revival of the —starting with in 2000—and the enduring dominance of , compounded by economic pressures such as declining toy sales that had been a key revenue driver for Toei's properties. In November 2025, Toei announced a revival of the franchise with a new Reiwa-era series set to air in February 2026, potentially replacing the time slot.

The early series, particularly the Space Sheriff trilogy (Gavan, Sharivan, and Shaider), established the franchise's foundation in interstellar themes.

Subseries Classification

The Metal Hero Series is commonly divided into subseries based on shared thematic elements, narrative styles, and production groupings, reflecting an evolution from individual space-faring protagonists to ensemble teams emphasizing collaboration and diverse threats. These classifications emerged retrospectively as Toei integrated earlier entries into the overarching franchise in the late 1990s, highlighting interconnections through crossovers and recurring motifs like metallic armor and high-tech weaponry. The foundational Space Sheriff Trilogy comprises Uchū Keiji Gavan (1982), Uchū Keiji Sharivan (1983), and Uchū Keiji Shaider (1984), centering on interstellar law enforcement officers dispatched from the United Galaxy Space Police (UGSP) to battle the imperialistic Makuu Empire and its variants. These series feature solo heroes enhanced by symbiotic suits that amplify human abilities, engaging in high-stakes space battles and Earth-based infiltrations, with a consistent universe reinforced by guest appearances and shared antagonists like the Makuu executives. The trilogy's progression builds narrative continuity, as Sharivan follows Gavan's legacy in combating the same empire's remnants, while Shaider introduces temporal elements against a reimagined foe, establishing the franchise's core of heroic isolation amid cosmic tyranny. Following a transitional entry in Kyojū Tokusō Jaspion (1985), the mid-1980s subseries—often grouped as the robot and cyborg-focused era—includes Jikū Senshi Spielban (1986), Chōjinki Metalder (1987), and Kido Keiji Jiban (1989), bookended by the ninja-themed (1988). These installments emphasize artificial heroes driven by personal vendettas: Spielban as a dimensional warrior avenging his family's enslavement, Metalder as an amnesiac android uncovering his military origins, and Jiban as a rebuilt defending urban environments from criminal syndicates. Shared elements include interfaces, AI companions, and transformations for city-scale defense, shifting the focus from galactic patrols to intimate, technology-mediated struggles against corporate or otherworldly oppressors, with subtle cross-references like recurring tech motifs. The early 1990s marked the Winspector Trilogy, encompassing Tokkei Winspector (1990), Tokkyū Shirei Solbrain (1991), and Tokusō Robo Janperson (1993), which pivots to enforcement with multi-member teams integrating human officers and robotic allies against and high-tech crimes. Winspector deploys a trio of detectives with powered suits and patrol vehicles for , Solbrain expands to a larger force tackling anomalies, and Janperson features a rogue android detective solving mysteries while grappling with his programmed directives. This grouping underscores dynamics, ethical dilemmas in policing futuristic threats, and ensemble action sequences, evolving the solo-hero model into coordinated operations that blend gritty realism with speculative elements. Subsequent series from the mid-1990s, such as Blue SWAT (1994), Jūku B-Fighter (1995), B-Fighter Kabuto (1996), Kabutack (1997), and Tetsuwan Tantei Robotack (1998), represent a diverse phase blending SWAT-style tactical units, insect-inspired bio-armor, and comedic detective formats, bridging Metal Hero aesthetics toward Super Sentai influences. Blue SWAT deploys elite anti-alien squads in powered exosuits for covert urban warfare, while the B-Fighter entries introduce beetle-themed warriors merging martial arts with monstrous summons against interdimensional invaders, culminating in lighter, kid-oriented robot sleuths in Robotack. This progression highlights a broadening scope—from lone interstellar guardians to collective defenses against escalating, multifaceted dangers—fostering greater crossover events and thematic hybridization before the franchise concluded.

Production Details

Key Creative Staff

The Metal Hero Series was primarily produced by , with production credits often attributed to the collective Saburo Yatsude, used by the studio's team to represent collaborative oversight on scripting, planning, and execution across multiple entries. This encompassed various staff members who shaped the franchise's high-tech aesthetics and episodic structure, ensuring consistency in visual effects and narrative arcs. A pivotal figure in the early development was producer Susumu Yoshikawa, who spearheaded the launch of the series with (1982) and continued through entries like (1983) and (1984), influencing the franchise's shift toward interstellar law enforcement themes and practical special effects integration. Yoshikawa's leadership emphasized stunt-driven action and ensemble dynamics, drawing from his prior work on series to elevate Metal Hero's production values. Head writer Shozo Uehara played a central role in crafting the foundational scripts for the Space Sheriff trilogy (Gavan, Sharivan, and Shaider), as well as Kyojuu Tokusou Jaspion (1985) and Dimensional Warrior Spielvan (1986), where he established recurring motifs of technological heroism against cosmic threats and moral dilemmas for young protagonists. Uehara's contributions extended to later series like Choujuu Liveman crossovers, but his Metal Hero work focused on blending adventure with ethical storytelling, often incorporating elements that influenced tone shifts toward more ensemble-based narratives in subsequent subseries. Directors varied across the franchise but featured recurring Toei tokusatsu veterans who emphasized dynamic action choreography. For Gavan, Yoshiaki Kobayashi directed 14 episodes, including the premiere, pioneering innovative camera techniques and high-energy fight sequences that set a benchmark for the series' fast-paced, gadget-heavy combat style, impacting the overall visual tone of early entries. Later directors like Hideo Tanaka handled multiple episodes in the Space Sheriff trilogy, refining suit actor performances and explosion effects for greater realism; Atsuo Okunaka directed several episodes of Gavan. In mid-franchise series such as Mobile Cop Jiban (1989) and Special Rescue Police Winspector (1990), writers like Nobuo Ogizawa and head writer Noboru Sugimura introduced procedural elements, shifting the tone toward urban rescue operations while maintaining collaborative suit design from Toei's in-house effects unit. These patterns of staff rotation fostered a unified production pipeline, with directors often returning for V-Cinema specials to preserve core action choreography standards.

This table highlights representative patterns; full credits involved rotating teams from Toei's tokusatsu department, promoting cross-franchise expertise in effects and stunts. Noboru Sugimura's writing in the 1990s entries like Jiban and the Rescue Hero trilogy further emphasized themes.

Music and Themes

The music of the Metal Hero Series played a pivotal role in establishing its heroic and sci-fi atmosphere, with composers crafting scores that blended orchestral elements with synthesizers to evoke a sense of metallic . Michiaki Watanabe, also known as Chūmei Watanabe, served as the primary composer for the Space Sheriff trilogy—Space Sheriff Gavan (1982), Space Sheriff Sharivan (1983), and Space Sheriff Shaider (1984)—delivering energetic themes that underscored the interstellar adventures and high-stakes battles. His work extended to early entries like Kyojuu Tokusou Jaspion (1985), where he adopted a more contemporary style incorporating electronic instrumentation to match the series' evolving technological motifs. In the 1990s, Eiji Kawamura took on composing duties for several later installments, including (1996), contributing dynamic scores that maintained the franchise's signature intensity while adapting to the era's action-oriented narratives. Iconic opening themes, such as "Uchū Keiji Gavan" from , performed by with lyrics by Keisuke Yamakawa, emphasized themes of heroism, courage, and unyielding justice, with lines like "Light the fire in your chest engine" rallying viewers to embrace a bold, unstoppable spirit. These songs were prominently featured at the start of episodes to set an inspirational tone, often reprised during key transformation or battle sequences to heighten dramatic tension. The sound design across the series relied heavily on electronic scores that highlighted metallic clangs, laser-like synth pulses, and futuristic drones, creating an immersive auditory landscape for the heroes' armored exploits. Composers like employed leitmotifs to distinguish characters, such as triumphant fanfares with brass swells for protagonists like Gavan to symbolize victory and resolve, contrasted by dissonant, echoing tones for villains to convey menace and otherworldliness. This approach not only amplified the action but also reinforced the franchise's core identity of mechanical guardians battling cosmic threats. Merchandising efforts capitalized on the music's popularity through various CD releases in during the 1980s and 1990s, including soundtrack compilations like the TV Original BGM Collection and hit song anthologies featuring opening and ending tracks. These albums, often remastered for later editions, allowed fans to relive the series' auditory highlights, while live performances by singers like Kushida at events further promoted the themes, blending music with on-stage appearances to boost fan engagement.

Media Expansions

Theatrical Releases

The Metal Hero Series spawned approximately 10 theatrical releases from 1984 to 2014, primarily produced by as big-screen extensions of the television programs. These films often premiered during Japanese holiday periods, such as in March or winter vacations in December, to maximize family attendance and boost merchandise sales, contributing to the franchise's enduring popularity among fans. They expanded the core narratives with epic-scale confrontations, new villains, and occasional crossovers, bridging episodes or seasons while introducing enhanced and stunts not feasible on TV budgets. A representative early entry is Uchuu Keiji Shaider: The Movie (1984), released on July 14 with a runtime of 24 minutes. The plot centers on Space Sheriff Shaider confronting the formidable Meteor Gunman Omega in a intense duel that tests his combat suit's limits and uncovers a plot threatening Earth. Key cast includes Hiroshi Tsuburaya as Dai Sawamura/Shaider, Naomi Morinaga as his partner Annie, and Shōzō Iizuka voicing the antagonist Great Emperor Kubilai; it directly connects to the TV series by occurring between episodes 19 and 20, amplifying the ongoing battle against the Fuuma organization. Another example from the Space Sheriff trilogy is Uchuu Keiji Shaider: Pursuit! The Strange Kidnappers! (1984), which premiered on December 22 with a 25-minute runtime. Shaider pursues a of extraterrestrial kidnappers targeting children, leading to high-stakes chases and rescues that highlight his high-tech arsenal. The film features returning cast like Tsuburaya as Shaider and Morinaga as Annie, alongside guest actors such as as Kojiro Oyama; it ties into the holiday season release strategy, serving as a festive extension of the series' themes shortly after the first film's summer debut. The series' theatrical output continued with films like : The Movie (1987), released March 14 for a 29-minute runtime, where Metalder battles the Gobos Army in an escalated robot-vs.- showdown, starring Shun Yashiro as Metalder and connecting to mid-season TV arcs. A subsequent entry is Kidou Keiji Jiban: The Movie (1989), released on July 15 with a 25-minute runtime. The film presents a completely original story, not a re-edit of the TV series, in which Jiban confronts Doctor Giba, who kidnaps children to harvest their genes for creating ultimate Bionoids at a monster factory. Key cast includes Shoutaro Kusaka as Naoto Tamura/Jiban, and it serves as a stand-alone adventure accessible to new viewers while featuring series elements. Later entries shifted toward crossovers, such as vs. Uchuu Keiji Gavan: The Movie (2012), a 70-minute feature released January 21 that revives Gavan ( reprising his role) alongside heroes in a multiverse-threatening crisis, grossing modestly in across 172 theaters while honoring the franchise's legacy. These releases, while shorter than standard features, emphasized spectacle and lore expansion, often achieving commercial viability through toys and posters, with total franchise theatrical earnings supporting Toei's ecosystem into the 2010s.

V-Cinema Productions

The V-Cinema productions within the Metal Hero Series encompass OVAs and specials that prolonged individual series narratives and facilitated franchise crossovers following the conclusion of their television broadcasts. These releases, produced by , primarily served as by reuniting established characters in fresh scenarios and supported merchandise promotion, particularly , in the absence of ongoing TV episodes. Ranging from 45 to 60 minutes in length, they were initially distributed via and in the 1990s, transitioning to DVD and Blu-ray for later revivals, often bridging gaps between series or exploring post-TV developments. In the post-franchise era after 1999, V-Cinema revivals revitalized the Space Sheriff subseries. Toei announced Next Generation in 2014 as a V-Cinema project, starring Naoto Adachi as the new Sharivan in a story confronting a revived criminal empire. The subsequent Next Generation, released in 2015, featured Yuma Ishigaki as the titular defending from interdimensional invaders, maintaining the classic high-tech action while updating character dynamics. These 50-minute OVAs marked a return to the franchise's roots, emphasizing legacy continuity without full serialization. The evolution culminated in multi-franchise crossovers under the Space Squad banner, blending Metal Heroes with elements. Space Squad: Gavan vs. Dekaranger (2017) pitted against Dekaranger foes in a 60-minute V-Cinema, highlighting interstellar police cooperation. This was followed by vs. Space Squad (2018), Toei's first V-Cinext release with a brief theatrical window before , where Kyuranger heroes allied with the Space Squad to battle cosmic villains, expanding the shared universe across Toei lines. No new V-Cinema productions have been released as of 2025.

International Reach

United States Adaptations

The primary adaptation of the Metal Hero Series was VR Troopers, a live-action television series produced by Saban Entertainment in collaboration with . Aired from 1994 to 1996, the show combined original American live-action segments filmed in with edited from three Japanese Metal Hero entries: Chōjinki Metalder (providing Ryan Steele's suit and much of the villain Grimlord's footage), Jikū Senshi Spielban (for Kaitlin Starr's and initial JB Reese's suits), and Kidō Keisatsu Jiban (for JB's upgraded suit in the second season). Saban acquired adaptation rights from Toei to repurpose the footage into a new narrative centered on three teenagers—Ryan Steele, Kaitlin Starr, and JB Reese—who use technology to transform into battling the virtual tyrant Grimlord and his forces across real and digital realms. The series ran for two seasons totaling 92 episodes (52 in the first season and 40 in the second), broadcast in first-run syndication across various networks, including slots on in many markets.
