Kotaro Minami (南 光太郎 Minami Kōtarō?) is the main protagonist of Kamen Rider Black and Kamen Rider Black RX. Starting with Kamen Rider Decade and continuing onto the later crossover movies, there are two Kotaro Minamis who are independently Black and RX.

Biography

Black

Kotaro was born on the day of a solar eclipse, along with his stepbrother Nobuhiko Akizuki, within the same hospital. Gorgom noticed this, and both brothers were entitled heirs to their leader, the Creation King's throne. After Kotaro's parents both died as a result of an apparent accident, Prof. Akizuki then adopted Kotaro alongside Nobuhiko as if they were brothers. On the night of their 19th birthday, they were captured by Gorgom and were remade into cyborgs and infused with King Stones. Kotaro received the "Stone of the Sun" to become Century King Black Sun (世紀王ブラックサン Seikiō Burakku San?). However before the final brainwashing Soichiro Akizuki interrupted the final stage of the process with Kotaro barely escaping.

Having been pursued by Gorgom after his escape, Kotaro discovers his newfound ability to turn into the a grasshopper humanoid as a result of their surgery, along with his newfound super strength and cyborg abilities.

After receiving a letter from Soichiro, Kotaro secretly meets with his foster father and learns the truth about his childhood. Soichiro reveals to Kotaro that he agreed to join Gorgom in order to receive funding for his archaeological research in exchange for Kotaro and Nobuhiko to be operated on during their 19th birthdays. When Kotaro's father had refused to join the organization, Gorgom had him and Kotaro's mother assassinated. After Prof. Akizuki is killed by five of Gorgom's Spider Mutants, Kotaro transforms once again and takes the title of "Kamen Rider Black." He then vows vengeance against Gorgom and seeks to rescue Nobuhiko from their clutches. As Black, Kotaro gains support from Nobuhiko's younger sister, Kyoko, as well as Nobuhiko's girlfriend Katsumi. He would often be found working part-time with the two girls at the Capitola café. He would also gain allies in fight against Gorgom, such as Interpol officer Ryusuke Taki and Gorgom's own Whale Mutant.

Eventually Kotaro reunites with Nobuhiko; however, Nobuhiko was converted into the perfected Century King, Shadow Moon. In their fight, Black was killed and his family had to evacuate from Gorgom's reign over Japan. Eventually Black was resurrected and fought his way through hordes of monsters until fighting Shadow Moon and presumably killing him.

Using the Satan Sabre used by Shadow Moon, Black fought against the Creation King of Gorgom and destroys him. With the Gorgom defeated, Kotaro visits the Capitola bar before leaving for unknown parts.

RX

"I am the child of the sun! Kamen Rider Black! RX!"
―announcing his transformation to Black RX[src]

Half a year after the defeat of Gorgom, Kotaro is left homeless until he is adopted into the Sahara family. He became a helicopter pilot for his new family's business due to their connections, beginning a new life for himself. Unfortunately, five years later Kotaro was abducted into the Crisis Empire mother-ship. The Crisis Empire was aware of his identity as Black and gave him an offer to join them. Kotaro refused and fought back but was incapacitated when his King Stone is damaged. He was ejected into space to float aimlessly until the sun's radiation altered his King Stone. When his pod entered Earth's atmosphere, Kotaro miraculously survives and immediately discovers he had gained a new power in the shape of an evolved rider form. With his new power, Kotaro engaged the Crisis Empire forces as Kamen Rider Black RX.

Kotaro's campaign was long and grueling. In one instances, his adoptive sister Hitomi is kidnapped by Maribaron into the the Desert of Death in a plot to make her the Crisis Empire's only living heir. Kotaro attempts to rescue her using Deathgaron, only to discover a trap set by Maribaron. Deathgaron kills Hitomi, but in his grief and sorrow, RX invokes a new Rider power, RoboRider. Using his power, RoboRider fatally wounds Deathgaron before learning that the Hitomi killed was a fake and the real one was being taken to the Miraculous Valley. On his way, he meets Joe the Haze who is under the control of Nexticker, freeing him before they and Shigeru are captured by Maribaron and the Princess Karuoriya. It was after they break free that Kotaro realizes the princess is Hitomi, who was abducted to replace the real princess who died and was force grown by the nearby waterfall. When he attempts to restore Hitomi's memory, Kotaro is forced to surrender when the Triplon captured Shigeru and Joe. Kotaro was then placed into a room for a hole designed to counter his abilities as both RX and RoboRider for a slow painful death. His rage to save those he love invokes another new form, Bio Rider. After killing Triplon, with Shigeru's help, Kotaro succeeded in having Hitomi regain his memory as she and the others are returned to their original ages by the people who originally resided in the valley. With only Joe and Shigeru knowing his identity, Kotaro returns to Earth.

During the middle of the series, Shadow Moon mysteriously returns to seek revenge against him, shortly after, Shadow Moon was finally defeated when RX thrust the Revolcane through Shadow Moon's King Stone, effectively turning him good shortly before he died and finally reverting to Nobuhiko. In the finale, he was helped by the 10 veteran Kamen Riders to destroy the Crisis Empire.

Kamen Rider Decade

2kotaros

The two alternate Kotaros from the World of Black RX and Black respectively.

In Kamen Rider Decade, a two episode arc features two different Kotaro Minamis - one from a world where he is Black RX, and one where he remains Black. The two even encounter each other. In Kamen Rider Decade: All Riders vs. Dai-Shocker, Black and Black RX appear together again, both portrayed by Tetsuo Kurata. After the battle, RX is one of the few past Riders shown to demorph into his human form, looking identical to the Kotaro Minami from the World of Black RX; Black never appears in his civilian form in the film. Official material related to the movie, like the pamphlet distributed alongside its theatrical showing, make it clear that Black RX is the original character, but Black is another Kotaro Minami who never became Black RX.

In the manga adaptation of All Riders vs. Dai-Shocker, based on the original script when the movie was planned to be the original ending of the TV series, Black, with V3 and Super-1 fight Decade, Diend and Kuuga in the final round of the Rider Battle as in the movie. When defeated Black, V3, and Super-1 expresses sadness that he "erased the Riders and can't meet them any more."

Later, also like in the movie, All Riders return to fight Dai-Shocker. Bishum/Sayo Kadoya zaps Yuusuke into Kamen Rider Kuuga Rising Ultimate and he fights Decade. The other Riders stand back and BLACK says Decade needs to fight this one alone. After Tsukasa gets through to Sayo, Black RX comes to save her from Nobuhiko Tsukikage/Shadow Moon and it is he who destroys the Stone of the Earth. Shadow Moon knows who Black RX is.

After this appearance, all following crossovers which featured All Riders would go on to feature Black and Black RX as separate independent characters, even while both continue to be the original Kotaro Minami, with the difference that one seemingly didn't go through the events of Black RX, without giving any specific explanation regarding it, not even in official extra materials.

A mishap caused by the Greeed Ankh unintentionally altered the timeline which enabled Shocker to utilize a Cell Medal to create the Shocker Greeed which defeated the Double Riders and seemingly erased the legacy of the Kamen Riders from history. In 2011, after Kamen Rider New Den-O's attempt to repair the damage, he along with Kamen Rider OOO and M-Ankh awaited execution. However, it was revealed the Double Riders had their brainwashing removed by a Shocker scientist.

The Double Riders joined with New Den-O and OOO to fight Shocker's forces, but were eventually defeated. When the order was given to kill everyone, V3 suddenly appeared, asserting that there were more than four riders. V3 was soon followed by all the other revived riders that came after him, including Black and RX, as even though Rider history was changed, the people's memories haven't changed.

After the riders were united, they faced off against Shocker's Great Leader. Later, when joined by a force of extra riders, Black and most other riders got on their motorcycles and performed the "All Rider Break", while RX hopped into his Ridron, together all Riders rammed into the Rock Great Leader and defeating it once and for all with the All Rider Break.

Kamen Rider Black appeared in a flashback where he was part of the group of Riders defeated by GokaiRed along with Hibiki, G3-X, Knight, Zolda, and Gatack. Both Black and RX, as separate heroes, were among the "All Rider" force during the "Super Hero Taisen" incident which resulted in the Kamen Riders and Super Sentai joining forces to defeat both Dai-Shocker and Dai-Zangyack. During the battle, Black RX is shown defeating a Gormin.

The combined forces of superheroes were able to turn the tide against the Madou army. They lined up and used their various finisher attacks to destroy the revived monsters.

After Demon King PsychoIcon-crosswiki was destroyed and the battle was finally over, RX appeared standing on a cliff with all the other heroes who appeared to help, to say goodbye to the heroes of recent years before taking their leave.

Seven Legendary Riders (with Stronger substituted with Black)

"Because the ones who brought Badan to the surface were the Heisei Riders."
"We have no choice but to eliminate the detestable Heisei Riders along with Badan!
"
―Black and RX explain to Tsukasa why he and the other Heisei Riders have to be defeated.[src]

How BLACK and RX are separate again, remained unknown, either both are from different A.R. Worlds or the original Kotaro Minami himself and an A.R. world counterpart. They are first appeared attacking Tsukasa and Shotaro to take a young boy Shu Aoi with them, and telling the Heisei Riders are now nuisance to Showa Riders. With Tsukasa escaping with Shu, Joker fends off both BLACKs until Baron arrived to aid Joker, defeating his RX half with a Punish Mash/Rider Kick combo, though BLACK manage to escape with the help of Amazon and Super-1, with the two Showa Riders beating Baron when he protects Joker from a Rider Kick/Great Slice combo. In a final round between Heisei and Showa sides, BLACK aids one of the Seven Legendary Showa Kamen Riders, replacing Stronger, when the latter is defeated by Kabuto.

He faces Kamen Rider Joker, with the two Riders taking each other out with their Rider Kicks. Gaim is soon left as the last Rider standing before Ambassador Darkness of the Badan Empire reveals himself to be Ryo Murasame (Kamen Rider ZX). Together, they restore the other Riders and all 30 Kamen Riders defeat the Badan Empire. Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai

After being transformed into a cyborg and having the holy King Stone called the "Stone of the Sun" implanted into him, Kotaro became Kamen Rider Black who used the power of the King Stone to transform and charge his attacks.

After being ejected into space by the Crisis Empire, Kotaro's King Stone evolved giving him the power to use the more powerful and versatile Black RX form.

Rider Machines

Combat Techniques and Other Body Parts

  • Rider Punch and Rider Kick: The primary killer moves in the entire series were the Rider Punch and Rider Kick which is charged with King Stone Energy at the right fist and the right foot. After delivering either one or both moves to any monsters, they would be engulfed in flames before finally destroyed. Kamen Rider Black discovered his weakness when he was fighting a Crab monster. His Rider Punch had no effect on the monster due to its strong shell. To increase his capabilities, Kamen Rider Black trained himself to find a new killer move to destroy the monster. While training, he discovered a new Rider Punch which was more effective and more deadly. These stronger variations of Rider Punch & Rider Kick gave out stronger force of light and were more blinding. The difference between the new and the old moves were that the new ones required Kamen Rider Black to touch his knees before hitting his enemies.
  • Rider Chop: This move was very rarely executed and did not have enough power to destroy a monster.
  • Multi-Eye: His eyes glow allowing him to see monsters' movements in the dark and detect their weaknesses.
  • Sensoring Ears: The triangular structures on both sides of his head would glow purple and enhance his hearing to super-human levels.
  • Rider Sensor: Kamen Rider Black's antennaes would move to detect monsters which were moving too fast to be seen.
  • Power Stripes: Black's striped bands on his neck and wrists would glow to repel any monsters' sticky fluids or goo on his body.
  • Dragon Shoot: A move only seen in episode 16. The Dragon Shoot was taught by the Interpol Agent, Ryusuke Taki. Ryusuke threw the Ultra Quartz (a wanted object in the episode) towards Kamen Rider Black where he quickly jumped and kicked it with one foot.
  • King Stone Flash: Perhaps the most powerful technique. By shouting out "King Stone Flash", Kamen Rider Black could fire a burst of energy from his belt. It worked every time to fend off the villains; whether it's the High Priests or even the powerful Shadow Moon.

The collected sunlight and the power of King Stone will become the hybrid energy of Black RX. The Sun Bask also allow Black RX to recover from injury instantly under sunlight. As sunlight is main energy source of Black RX, when Sun Bask is damaged, Black RX will lose his power. (Although it can be repaired by the power of the King Stone and sunlight)
Revolcane

Revolcane

  • Revolcane - The Revolcane (リボルケイン Riborukien?) is Black RX's sword comes out from his Sunriser belt. It has a light saber-like mode that executes the Revolcrash finishing attack, where Black RX thrusts with the Revolcane, sending an unlimited surge of energy into the enemy.

B

Acrobatter

  • Acrobatter - The Acrobatter is the revived version of Black's old motorcycle, the Battle Hopper. It is now capable of speaking coherent Japanese, and often has conversations with Kotaro. Whenever Black RX transforms into any of his two other forms, it does the same.

Sunriserlight

Releases the light from Sun Riser

When Black RX perform King Stone Flash in front of Gedoll Ridoll, It give the enemy a chance to absorb all the power of King Stone.

Behind the scenes

Portrayal and Casting

Kotaro Minami is played by Tetsuo Kurata (倉田 てつを Kurata Tetsuo?). Kurata auditioned for the role of Kotaro Minami in January 1987, when he had just graduated from high school. In a 2006 interview, Kurata had stated that, during the audition, he hadn't been able to portray the character appropriately, and did not think he would get the role. To his surprise, he was chosen by Shōtarō Ishinomori himself to play the lead role, beating some 8,000 other contestants. During this period, Kurata underwent intense training that included stage combat techniques, physical exercise sessions and acting and singing lessons.

On October 4, 1987, Kamen Rider Black premiered on TBS to public and critical acclaim. The success of the series, which ran for 51 episodes, generated enough interest from Toei Company executives to persuade them to produce a sequel, something unprecedented in the Kamen Rider Series franchise. After finishing his work on Black, Kurata was approached by Toei and renewed his contract for one more year in exchange for a salary raise to work on Black's sequel, Kamen Rider Black RX, this resulted in him becoming the only actor to be the star of two shows in the Kamen Rider Series. In a 1989 magazine interview, Kurata said he preferred Black over Black RX, quoting the comedy from the latter as "excessive". It is rumored that Kurata declined later invitations to reprise his role as Kotaro in fear of being typecasted, but such rumors were never confirmed.

As Kamen Rider Black, his suit actor was Jiro Okamoto (岡元 次郎 Okamoto Jirō?) who also did work for RX along with Robo Rider and Bio Rider. Other suit actors were Tokio Iwata (岩田 時男 Iwata Tokio?), who did Robo Rider and Bio Rider, and Toshiyuki Kikuchi (菊地 寿幸 Kikuchi Toshiyuki?) who did work for Robo Rider.

Tetsuo came back to voice Kotaro Minami/Kamen Rider Black in Kamen Rider: Seigi No Keifu. In 2009, Kurata returned as Kotaro Minami in Kamen Rider Decade where he played both his Black and Black RX incarnations at the same time. The alternate RX appeared first appeared in episode 26, RX! Dai-Shocker Attack, then joining forces with the A.R. Black in the next, Black × Black RX. That same year, he had a cameo as the original Kotaro Minami, untransformed from Black RX, in the movie, Kamen Rider Decade: All Riders vs. Dai-Shocker. In All Riders vs. Dai-Shocker, Jun Watanabe (渡辺 淳 Watanabe Jun?) did suitwork for RX, Robo Rider, and Bio Rider while Jiro Okamoto also did work for RX and Black.

In OOO, Den-O, All Riders: Let's Go Kamen Riders, Kamen Rider Black was voiced by Ibuki (勇吹輝?) while Jiro Okamoto acted as suit actor for RX.

In Kamen Rider × Super Sentai: Super Hero Taisen, Jiro Okamoto again acted as suit actor for RX, while Hirofumi Tanaka (田中 大文 Tanaka Hirofumi?) provided the voice for Kamen Rider Black.

In Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai, both Black and Black RX were voiced by Kenichi Suzumura (鈴村 健一 Suzumura Ken'ichi?) and Hiroshi Kamiya (神谷 浩史 Kamiya Hiroshi?).

Rider No.

As the leading Rider protagonist of Kamen Rider Black and Kamen Rider Black RX, Kotaro Minami is labeled Kamen Rider #11 (仮面ライダー11号 Kamen Raidā Jūichigō?) and Showa Rider #11 (昭和ライダー11号 Shōwa Raidā Jūichigō?) as Kamen Rider Black & Kamen Rider #12 (仮面ライダー12号 Kamen Raidā Jūnigō?) and Showa Rider #12 (昭和ライダー12号 Shōwa Raidā Jūnigō?) as Kamen Rider Black RX. Quiz! Decade Countdown!!

Two Kotaro Minamis

  • There have been six instances where Kamen Rider Black and Kamen Rider Black RX have existed independently from each other.
    • The first was in Kamen Rider: Run All Over the World where a time warp causes Kotaro to meet his past self. He also meets himself in his other forms, Robo Rider and Bio Rider, who also arrived due to a time warp.
    • The second was in the two episode arc (RX! Dai-Shocker Attack/Black × Black RX) of Kamen Rider Decade, in which the World of Black and the World of Black RX were treated as separate dimensions.
    • The third was in Kamen Rider Decade: All Riders vs. Dai-Shocker. All returning Riders in this movie were stated to be the originals by the producers and assorted official material, like official site bios, but two Kotaro Minamis still coexisted, both portrayed by Tetsuo Kurata, similarly to the Decade TV show appearance, meaning one or both of them could have been the Kotaro Minamis from either the World of Black or World of Black RX.
    • The fourth was in OOO, Den-O, All Riders: Let's Go Kamen Riders, where there wasn't a proper explanation for their combined appearance. However it can be assumed that they are both Kotaro from different points in time similar to the aforementioned Run All Over the World.
    • The fifth was Super Hero Taisen, which yet again features both side by side, but only in the final battle, without any specific explanation for their combined appearance. The movie pamphlet distributed alongside theatrical showings of the movie references how Black's destined battle against Shadow Moon continues even 25 years later. However, since Kamen Rider Decade is involved, it can be assumed that the Kamen Rider Black in the movie is the one from the World of Black, where Kotaro never lost his powers.
    • The sixth instance was in Kamen Rider Taisen when both of them appear to battle Kamen Rider Joker. Once again, no explanation is given. But, considering Decade's involvement in the film it is likely that one or both of them are A.R. World Riders.

Dub names

  • Kotaro is renamed as Robert Akizuki in the Filipino dub and as Isamu Minami in Brazil.

Rider notes

  • Kotaro is the only Rider to be the leading protagonist of two shows in the Kamen Rider Series. Because of this, he also has the following distinctions:
    • Kotaro currently holds the record of the Rider with the most appearances.
    • Kotaro is currently the only Rider to get a completely new set of powers at the cost of his old ones. This would happen several times in the early seasons of Power Rangers, the American franchise which is adapted from the Super Sentai series. Ironically, as only Black RX was adapted into Saban's Masked Rider, Masked Rider's first form was RX (along with Super Gold (Robo Rider) and Super Blue (Bio Rider), while the original Kamen Rider Black costume was never used in the series.
  • As Black RX's Bio Rider form, Kotaro is the first Kamen Rider who has the ability to turn into liquid via an alternate form, this power would be repeated by future Kamen Riders OOO and Wizard who can become liquid via Shauta Combo and Water Style respectively.
  • Both Black and RX are homaged by Leona Heidern, a character from SNK's King of Fighters series of video games. Her Rebel Spark desperation move is almost an exact copy of the Revolcrash, including the leaping stab, shower of sparks, and elaborate pose before the opponent explodes. However, Leona performs the move with her bare hands, and the explosion is caused by her planting an explosive on her opponent. Additionally, Leona's jumping Strike Attack (Hard Punch + Hard Kick together) is identical to Black's Rider Kick, even featuring a red energy aura around her feet.
  • Black RX's Revolcane and Bio Blade are similar to the Lightsabers from the original Star Wars trilogy as the movies were popular in Japan during the 1980s.
  • Kotaro is the only Rider to get a new name upon Form Changing (going from Kamen Rider Black RX to just Robo Rider/Bio Rider).
