Question: Who played the leader of the Kamen Rider?

Kamen Rider (1971 TV series)

Main Page

Kamen Rider(仮面ライダー,Kamen Raidā, Masked Rider) is a tokusatsu superhero television series and weekly science fiction manga created by manga artist Shotaro Ishinomori. It debuted on television on April 3, 1971, and ran until February 10, 1973, airing on the Mainichi Broadcasting System and NET TV (now TV Asahi). The manga adaptation was also featured in Shōnen Magazine around the same period. The series has evolved into a franchise with many subsequent annual iterations. The cultural impact of the series in Japan resulted in astronomer Akimasa Nakamura naming two minor planets in honor of the series: 12408 Fujioka, after actor Hiroshi Fujioka, known for his portrayal of Takeshi Hongo/Kamen Rider 1,[1][2] and 12796 Kamenrider, after the series itself.[1][3]
Story
The series takes place in a world plagued by Shocker, a mysterious world-wide terrorist organization formed by remaining members of the Nazis. To further its plans for world domination, Shocker recruited its agents through kidnapping, turning their victims into mutant cyborgs and, ultimately, brainwashing them. However, one victim named Takeshi Hongo escaped just before the final brainwashing. With his sanity and moral conscience intact, Hongo battled Shocker's minions as the grasshopper-themed altered human(改造人間,kaizō ningen) superhero Kamen Rider. Another victim of the altered human process, freelance photographer Hayato Ichimonji, became Kamen Rider 2 after Kamen Rider, who renamed himself as "Kamen Rider 1", saved him from Shocker's brainwashing. Assisted by motorcycle race team manager Tobei Tachibana and FBI agent Kazuya Taki, the Kamen Riders fought in both solo and partnered missions against Shocker and its successor organization, Gel-Shocker.
Manga
Many manga based on the original Kamen Rider series have been published, but only one was penned and drawn by Ishinomori himself. Ishinomori was also the author of one chapter of the Kamen Rider Amazon manga and the entire Kamen Rider Black manga.  However, those manga were based on sequels to Kamen Rider, rather than the original series.
The original manga, published in 1971, initially follows a path resembling the first few episodes of the TV series, from basic plot to creature designs. However, when Hongo leaves the story, the series diverge greatly. In the TV show, Hongo travels abroad to fight Shocker in other countries, leaving Japan's protection to Hayato Ichimonji, a freelance cameraman who was experimented on by Shocker but saved by Hongo, becoming the second Kamen Rider. In the manga, Hongo never left Japan. He was confronted with twelve "Shocker Riders" and was subsequently mortally wounded during his battle against them. Hayato Ichimonji, one of the twelve Shocker Riders, receives a head injury during the fight and regains his conscience as a result. He then turns against Shocker and succeeds Hongo's role as Kamen Rider. In spite of the damage to his body, Hongo's brain survives and guides Ichimonji, the two fighting as one.
Hongo eventually returns as a Rider in both stories, but starting with Hayato's debut, villains and even basic story development greatly diverge between the two versions. The manga portrays a seemingly hopeless battle against Shocker, an organization with ties to governmental conspiracies that seems much bigger than either of the two Riders. The live action TV shows portray the Riders as heroes strong enough to bring down Shocker, only to see it replaced by similar organizations led by Shocker's mysterious leader. The Shocker Riders eventually appear in the TV series, too, but they looked different and had different abilities. There were also only six Shocker Riders, rather than the manga's 12.

Shocker
Shocker(ショッカー,Shokkā) is a terrorist organization formed by former Nazis. Its name is an acronym for "S</b>acred H</b>egemony O</b>f C</b>ycle K</b>indred E</b>volutional R</b>ealm", as revealed in the movie reboot. Shocker's goal is to conquer the world. To this end, their scientists turn humans into superhuman cyborgs by surgically altering them with animal DNA. Virtually all of its members are modified in some way. The original manga showed that Shocker had influence over the governments of the world. Its founders had ties to the Nazis, Illuminati and the Kamen Rider Spirits manga makes references to the group's support by the Badan Empire.
Ruthless and merciless, Shocker would often kidnap prominent scientists and force them to work for the organization, then kill them when their usefulness was at an end, or if they attempted to escape. The decision to kidnap and modify college student Takeshi Hongo proved to be their undoing. He was intended to be another of Shocker's powerful cyborg warriors, a grasshopper-human hybrid, but he escaped and opposed them as Kamen Rider 1. A later attempt to create a second, more powerful Kamen Rider backfired when the intended victim, Hayato Ichimonji, was rescued by the original Rider before he was brainwashed. Ichimonji joined Hongo as Kamen Rider 2. The pair, known as the Double Riders, put an end to Shocker, and later its remnants, who formed Gel-Shocker after their first defeat.
In OOO, Den-O, All Riders: Let's Go Kamen Riders, Shocker, although with a membership and leadership covering Gel-Shocker members from the original TV series, obtained a Core Medal and modified it into the Shocker Medal. Though they were originally unable to use it, the appearance of the Greeed Ankh in their time enabled the organization to obtain one of his Cell Medals and create the Shocker Greeed. This altered time so that Shocker defeated the Double Riders and managed to conquer all of Japan and eventually the world, setting up a union with many of the other organizations that originally emerged after Shocker's destruction. The group is ultimately defeated by the Kamen Riders.
But as revealed in Kamen Rider OOO onwards, there are some surviving members of the Shocker organization, even from Badan Empire who went into hiding to gather data of the Kamen Riders' battles against some of their respective kaijins many years. But during the events of Super Hero Taisen GP: Kamen Rider 3, Shocker's remaining scientists created a History Modification Machine that they use to send a time displaced cyborg called Kamen Rider 3 back in time to destroy the Double Riders in the aftermath of Gel-Shocker's defeat, creating a new timeline where Shocker rules the world with some Kamen Riders in their service. Luckily, the apparent destruction of the History Modification Machine restores the timeline (with the exception of Go Shijima/Kamen Rider Mach who was killed by Cheetahkatatsumuri), only to be found out during the events of D-Video Special: Kamen Rider 4 that Shocker secretly uses it to create time loops and alters the timeline once more, allowing to create Kamen Rider 4, as well as  the revalation that they have been targeting Takumi Inui, due to his sacrifice-less wish to ensure that no one dies like what happened to one of his old allies to create a loop. As Takumi is about to destroy the machine, the Great Leader of Shocker appears with an appearance identical to Takumi's. In the end, Takumi destroys the machine and disappears alongside the modified timeline, restored back to its original timeline once more. Though most of his allies who do not originate from Kamen Rider 555 TV series like from Kamen Rider Drive, and even Kamen Rider Den-O's Kamen Rider Zeronos do not remember if they had encountered Takumi, only some of Takumi's old friends from Kamen Rider 555 TV series, including Naoya Kaido still remember Takumi. 
In the movie Kamen Rider 1, there is a civil war between the original Shocker and a newly formed organization called Nova Shocker in attempt to kidnap Mayu, Tobei Tachibana's granddaughter, and release the Alexander the Great Gamma Eyecon from her body, in order to obtain its power. As all of the revived Ambassador Hell's Shocker fraction had been annihilated completely, leaving only himself, and also after he witnessed how dangerous the Alexander Gamma Eyecon is, he makes an uneasy alliance with Kamen Riders Ghost, Specter and a newly improved Kamen Rider 1.
Great Leader of Shocker(ショッカー首領,Shokkā Shuryō): The high ruler of the organization and main antagonist of the series. He appears for the first time in short video footage shown in episode 34, although his appearance there is mostly hidden by shadows. He talks with his followers through speakers on Shocker's emblems in the multiple outposts. The Great Leader is a cruel being who does not have qualms in sacrificing his minions during moments of crisis or failure.[4] He takes various forms, his first being a Cyclopean gorgon in crimson robes in the original series, his second being a skeletal creature in Kamen Rider V3, following a skull-faced insect who lead a mini-restoration of shocker known as Black Satan, and his true form is known as the Great Leader Rock(岩石大首領,Ganseki Daishuryō) in Kamen Rider Stronger a giant humanoid rock man controlled by a large one-eyed cybernetic brain.
Colonel Zol/Werewolf(ゾル大佐/狼男,Zoru-taisa/Ōkami Otoko, 26-39, Kamen Rider vs. Shocker & V3 27 & 28) (a.k.a. Gold Werewolf(黄金狼男,Ōgon Ōkami Otoko)): From Shocker's Middle East branch, his true form was a wolf monster. He was also a disguise specialist, able to mimic Taki's appearance almost perfectly using only make up during his debut. His personal mark, worn by the soldiers of his own Shocker outpost and used in his official correspondence, was the Shocker emblem, but with the bird's head replaced by a wolf's.[5] He confronted Kamen Rider 2 himself in episode 39 and after a lengthy fight was toppled off a cliff by Kamen Rider 2's Rider Punch, destroying him. Gold Werewolf briefly appeared in Kamen Rider vs Shocker among the members of the resurrected monster army. In Kamen Rider V3, episode 27, Colonel Zol is resurrected alongside the other 3 great Shocker and Gel-Shocker commanders from the original TV series by Destron. He aims to become a Destron commander, replacing Doctor G. However, in episode 28, after Kamen Rider V3 escaped from Destron's base, a self-destruction sequence was activated, and Colonel Zol was unable to escape, dying again with it. In Kamen Rider Spirits manga, he is revived with other Shocker commander as a soulless pawn of Badan Empire.
Doctor Shinigami/Ikadevil'(死神博士/イカデビル,Shinigami-hakase/Ikadebiru, 40-52, Kamen Rider vs. Shocker, 61, 63 & 68, V3 27 & 28, Decade: All Riders vs Great-Shocker & Let's Go Kamen Riders): From Shocker's branch in Switzerland, he took over Japan's command after Zol's death until Ambassador Hell appeared. However, he returned to Japan in episode 61, working together with Ambassador Hell and also attempting his own plans. He had a cold and calculating behavior. In episode 68, he captured Tobei to help training him for his battle with Kamen Rider 1, but that only resulted in Tobei learning about his weakness. Discarding his cape when he faced Hongo for the last time, Shinigami assumed his squid monster form to fight Rider 1 with his tentacle whip, while Ichimonji was held off by the Shocker Combatmen. With Tobei's guidance, Kamen Rider 1 managed to overpower Ikadevil and weaken him with a Rider Chop before sending Ikadevil falling to his death with his Rider Tailspin Shoot. Ikadevil tried to rise once more, only to fall down and explode. Doctor Shinigami was resurrected by Destron in Kamen Rider V3, episode 27, and speculated about how he had been brought back to replace Doctor G, only to learn that he was there just for a new operation. Shortly afterwards, in episode 28, he died when Destron's base accidentally self-destructed. He is revived as a soulless pawn of Badan Empire alongside Colonel Zol and Ambassador Hell in the Kamen Rider Spirits manga.
'Ambassador Hell/Garagaranda(地獄大使/ガラガランダ,Jigoku-taishi/Garagaranda, 53-62, 64-67, Kamen Rider vs. Ambassador Hell & 69-79, V3 27 & 28, Decade: All Riders vs Great-Shocker & Let's Go Kamen Riders): Summoned from Shocker's branch in Southeast Asia, he took command of the organization in Japan. His true name was Damon(ダモン) according to Kamen Rider Spirits. He used an electromagnetic whip and an iron claw as his weapons. In episode 79, after capturing the Riders' friends, he called Hongo out as he assumed his rattlesnake monster form, able to burrow underground and use his whip arm as a weapon. Kamen Rider 1 battled Garagaranda while Taki freed Tobei and the others, managing to use his Rider Kick on the monster. Reverting to his normal mode, Hell cursed the Riders and screamed to Shocker's perseverance before he died, exploding. Afterwards, the Great Leader destroyed the original Shocker. In spite of his failure, Ambassador Hell was resurrected by Destron in Kamen Rider V3, episode 27. In episode 28, his sneaky behavior ended up leading to the prisoner V3 capturing him and escaping from the Destron base. Soon afterwards, Ambassador Hell returned to the base, only to die in its self-destruction. Ambassador Hell returns in Kamen Rider Spirits manga, working for Badan Empire. But his difference among the other revived members is that he had his own consciousness, it is revealed that the Silver Skull used to revive him is capable of bringing back the dead person's memories. In Kamen Rider ZX, Ambassador Darkness, Ambassador Hell's younger cousin, appeared as a Badan Empire leader.
Shocker Combatmen(ショッカー戦闘員,Shokkā Sentōin): Black uniformed soldiers, some which have skeleton markings on their torsos. They are normally easily defeated by the Riders, often without even needing to transform. Their trademark is a high pitched battle-cry.
Big Machine(ビッグマシン,Biggu Mashin): A character who only appears in Ishinomori's original Kamen Rider manga. Big Machine is Shocker's highest commander and main antagonist in the manga. He also seems to be the one called "Great Leader" by some of the lower ranking Shocker members. He has a fully mechanized body and is behind Shocker's "October Project", which involves using a super computer to brainwash the population of Japan. He's able to match up the Riders in combat and launch attacks that disrupt electronic equipment, including Rider 1's and 2's own bodies. The design of his body was the base of Ambassador Hell's design in the TV show, although it was altered to allow a human face, and, unlike Big Machine, Ambassador Hell was kept a separate character from the Leader of Shocker. In Kamen Rider × Super Sentai: Super Hero Taisen, Big Machine is reimagined as a project of the Shocker/Zangyack Alliance to create a giant robot from Crisis Fortress and the Gigant Horse.
Gel-Shocker
Gel-Shocker(ゲルショッカー,Geru-Shokkā) was formed after the destruction of Shocker, with the remnants of the organization absorbing another organization Geldam(ゲルダム団,Gerudamu-dan) based in Africa. After Ambassador Hell's defeat, The Great Leader reorganized the organization from the ground up, destroying all remaining secret bases and even liquidating the remaining troop contingent in a bloody forest massacre witnessed by unfortunate campers. Gel-Shocker troopers wore bright purple and yellow costumes, were capable of traveling from one place to another by transforming into sheets that would drop down onto unsuspecting victims, and were capable of taking more blunt violent abuse than their predecessors
Gel-Shocker was led by the Great Leader of Gel-Shocker(ゲルショッカー首領,Geru-Shokkā Shuryō) and General Black(ブラック将軍,Burakku-shōgun), a commander originally from Geldam who had a monstrous leech/chameleon hybrid form called Hiruchameleon(ヒルカメレオン,Hirukamereon) who had the ability to suck blood by hugging humans, which was later used to revive Gel-Shocker Kaijin after already being defeated by the Double Riders, throwing leeches which cause the target to follow his orders, and turn himself invisible. Later, he fought the Double Riders on a roller coaster and was defeated by their Rider Double Chop while turned invisible. Weakened, he reverted to his human form and cursed the Double Riders before exploding. Eventually, General Black was resurrected and worked for Destron in an important operation, but ended up dying in the self-destruction of a Destron base. Black returned as a soulless pawn of the Badan Empire in the Kamen Rider Spirits manga, but he was defeated by a Rider Double Kick performed by Kamen Riders 2 and ZX.

Legacy
The Kamen Rider original series famously spearheaded launched "Second Kaiju Boom" or "Henshin Boom" on Japanese television in the early 1970s, greatly impacting the superhero and action-adventure genre in Japan.[7] The famous "henshin sequence", in which the title hero performs ritualistic poses and shouting a keyword to transform into his superhero form has since become a staple in Japanese pop-culture, inspiring superheroes and magical girl genres. Kamen Rider went to later produce a great number of spin-offs which remain in production today. Several Kamen Rider series were aired in Japan after the first Kamen Rider finished. After Kamen Rider Black RX ended production in 1989, the series was put on hold.
There were three movies released as the 1990s "Movie Riders", which were Shin Kamen Rider: Prologue, Kamen Rider ZO and Kamen Rider J. After the original creator Shōtarō Ishinomori's death, the Kamen Rider franchise was continued in 2000 with Kamen Rider Kuuga. As of 2018, twenty-nine Kamen Rider series have been made, with the newest being Kamen Rider Zi-O which premiered in September 2018.
As of 2005, a remake of the Kamen Rider series was made and reimagined with Kamen Rider The First and continued with Kamen Rider The Next released in 2007.
