Kohtaro Minami (南 光太郎, Minami Kōtarō), alternatively spelt Kotaro Minami,[1] is the main protagonist of both Kamen Rider Black and Kamen Rider Black RX. Starting with Kamen Rider Decade and continuing onto most of the later crossover movies, there are two incarnations of Kohtaro Minami who are independently Black and Black RX.


Kamen Rider Black

Kohtaro 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 Kohtaro's parents deaths from an apparent accident, Prof. Akizuki adopted Kohtaro alongside Nobuhiko and Kyoko. On the night of Kohtaro and Nobuhiko's 19th birthday, they were captured by Gorgom and were remade into cyborgs and infused with Kingstones. Kohtaro 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 they could remove Kohtaro's humanity, Prof. Akizuki intervened, with Kohtaro using Battle Hopper to escape from Gorgom's base.

Pursued by the High Priests of Gorgom, Kohtaro continued to run, eventually getting cornered on top of a building. There, Kohtaro is told by his pursuers of his physical alteration, before being subdued by their attacks. Just as the High Priests began carrying away Kohtaro however, the latter struggled to break free, falling on top of a warehouse.

The High Priests following after Kohtaro, Darom continuously used his telekinetic powers to punish him, blasting Kohtaro into a concrete wall. Amidst the rubble, Kohtaro regained his posture and transformed into Kamen Rider Black, surprising the High Priests. His newfound strength and abilities proving enough to simultaneously counter all three High Priests, Kohtaro successfully drove them away.

After receiving a letter from Prof. Akizuki, Kohtaro secretly meets with his foster father and learns the truth about his childhood. Soichiro reveals to Kohtaro that he agreed to join Gorgom in order to receive funding for his archaeological research in exchange for Kohtaro and Nobuhiko to be operated on during their 19th birthdays. When Kohtaro's father had refused to join the cult organization, Gorgom had him and Kohtaro's mother assassinated.

Displeased by Prof. Akizuki's continued submission to Gorgom, Kohtaro leaves him in disgust, allowing Gorgom's Spider Mutants to attack Prof. Akizuki. Arriving too late to save his foster father, Kohtaro holds Prof. Akizuki in his arms, with the dying man's last request for Kohtaro to save Nobuhiko and Kyoko.

Grieving Prof. Akizuki's death, Kohtaro transforms once again and takes the title of "Kamen Rider Black, vowing to stop Gorgom and save Nobuhiko. As Black, Kohtaro 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 some allies in fight against Gorgom, such as Interpol officer Ryusuke Taki.

Failing to re-kidnap Kohtaro, Gorgom fully deemed him a foe, sending several members to kill him and retrieve his Kingstone. From each battle, Kohtaro slowly became a formidable warrior, with even the highly trained Bilgenia and three High Priests being overpowered by him as Kamen Rider Black.

Eventually Kohtaro reunites with Nobuhiko; however, Nobuhiko was converted into the Century King, Shadow Moon. Taking his place as commander of Gorgom, Shadow Moon declares war on Kohtaro, intent on ruling the entire world. Though reluctant to face his best friend, Kohtaro found himself unable to avoid battling Shadow Moon, the latter fully intent to defeat his archenemy.

In their fight, just when Kohtaro was winning, the Creation King temporarily turned Nobuhiko back into human form. This caused Kohtaro to lose the fight as Nobuhiko turned back into Shadow Moon and launched a surprise attack. In a desperate attempt, Kohtaro tried to convince Shadow Moon that Earth belongs to all living things, and that Gorgom's actions were wrong. Shadow Moon in response stabbed him with the Satansaber. Shadow Moon then reached his hand towards Kohtaro's Kingstone, when Kohtaro suddenly turned back into his human form. The human form of Kohtaro reawakened the lingering humanity within Shadow Moon, causing the latter to retreat. Despite retaining his Kingstone though, Kohtaro's wounds were too grave to heal on his own, causing him to die. In response, his remaining family left Japan and people from across the country lost hope in the battle against Gorgom. Luckily though, the Whale Mutant used a special ritual to resurrect Kohtaro, as well as raising his power. Having been revived, Kohtaro fought his way through hordes of monsters until fighting Shadow Moon and unwillingly defeating him. Kohtaro was then mercilessly taunted by Shadow Moon who told him that he shall feel regret for the rest of his life knowing that he killed his best friend and step-brother Nobuhiko. Despite these cruel words, Kohtaro told Shadow Moon to stay alive so they can later escape together.

Using the Satansaber wielded by Shadow Moon, Black then fought against the Creation King of Gorgom and destroyed him. The base soon started to self destruct which prevented him from getting Shadow Moon out to safety. Kohtaro then looked at the ruins while saying Nobuhiko's name. With Gorgom defeated, Kohtaro visited the Capitola bar before leaving for unknown parts.


"I am the child of the sun! Kamen Rider Black! RX! (俺は太陽の子! 仮面ライダーBLACK! RX!, Ore wa Taiyō no ko! Kamen Raidā BLACK! RX!)"
―announcing his transformation to Black RX[src]

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

Kohtaro's campaign was long and grueling. In one instance, the family's daughter Hitomi is kidnapped by Maribaron in a plot to make her the Crisis Empire's only living heir. Kohtaro attempts to rescue her using Deathgaron, only to land in the Demon World's Desert of Death. He then ends up in a trap set up 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 Valley of Miracles. 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 Princess Karuoriya. It was after they break free that Kohtaro 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, Kohtaro is forced to surrender when the Triplon captured Shigeru and Joe. Kohtaro 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, Biorider. After killing Triplon, with Shigeru's help, Kohtaro 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 the Sahara Children knowing his identity, Kohtaro returns to Earth.

During the middle of the series, Shadow Moon mysteriously returns to seek revenge against him. Though not evolving in the same manner as Black, Shadow Moon was formidable as ever, rivaling the Crisis Empire itself. In their final duel, RX and Shadow Moon remained evenly matched with one another, neither side willing surrender. Amidst their battle, the Crisis Empire revealed to Kohtaro of two children they had taken hostage, much to his shock. Despite Kohtaro's pleas for Shadow Moon to stop, his words fell on deaf ears. Angered by Shadow Moon's cruelty, Kohtaro summoned his Revolcane, dealing a critical blow to his foe's Kingstone. Stumbling over, Shadow Moon admits defeat.

Immediately afterwards, Shadow Moon reveals to Kohtaro of the Crisis Empire's plan to flood Japan with erupted magma, having heard it from one of their monsters. With no time to be wasted, Shadow Moon states that he will save the two children held hostage while Kohtaro prevents the eruption. Surprised by this change of heart, Kohtaro sees a flash of Nobuhiko from Shadow Moon.

Referring to Shadow Moon as Nobuhiko once more, Kohtaro called out to him. Shadow Moon denied Kohtaro's words but still marched forward, all while urging Kohtaro to not waste time. Placing faith in Shadow Moon, Kohtaro proceeds to stop the Crisis Empire. Afterwards, he returned to Shadow Moon's location, confirming that the children had been rescued.

Shadow Moon lied still on a bed of flowers, with the two children worried whether he had died. Assuring them that their savior was just tired and sleeping, Kohtaro oversees the two return to their father, before focusing his attention back to Shadow Moon. Remembering Shadow Moon's last actions and the man he used to, Kohtaro decided that Nobuhiko had been restored in the end, no longer the ruthless Century King but his kind best friend once more. Evidently, Nobuhiko's body reverted back into human form in death, symbolizing Kohtaro's belief to be correct. In a sense, Kohtaro finally succeeded in his initial mission, having saved Nobuhiko like he promised to Prof. Akizuki, Kyoko, and Katsumi.

In the finale, he was helped by the 10 veteran Kamen Riders to destroy the Crisis Empire.

Kamen Rider: Run All Over the World

Black & Black RX with Biorider & Roborider in Kamen Rider: Run All Over the World.

In the film, the Crisis Empire devise a plan to defeat Kohtaro Minami by reverting him back to his old form of Kamen Rider Black and sending out several revived monsters after him. However, Kamen Rider Black is assisted by another RX, who used a time warp to help his past self.[2] The two are joined by RX's alternate forms of Roborider and Biorider, and the four Kamen Riders combine their powers to defeat the revived monsters.

Kamen Rider Decade

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

In Kamen Rider Decade, a two episode arc features two different Kohtaro 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 Kohtaro 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 Kohtaro 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. Shadow Moon knows who Black RX is. 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.

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 Kohtaro 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.

Let's Go Kamen Riders

RX as seen in Let's Go Kamen Riders.

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 and Shadow Moon face off once more.[src]

Kamen Rider Black appeared in a flashback where he was part of the group of Riders defeated by Gokai Red 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. Afterwards, a separate Kamen Rider Black joined forces with the Hikari Sentai MaskmanIcon-crosswiki.png, as they protected Earth in the same year, and launched an attack against the revived Shadow Moon and General Jark.

Black RX was part of a force of Rider and Sentai reinforcements led by Kamen Rider 1 and AkarengerIcon-crosswiki.png that came to assist the Riders and Sentai of recent years who were overwhelmed by the revived monster army of the Space Crime Syndicate MadouIcon-crosswiki.png. 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.png 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.

Kamen Rider Taisen

"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]

Black & Black RX as seen in Kamen Rider Taisen.

Seven Legendary Riders (with Stronger substituted with Black)

Black and Black RX appear as separate Riders again. They first appear telling the Heisei Riders to stay out of the current Badan crisis, attacking Tsukasa and Shotaro to take a young boy Shu Aoi with them when they refuse. Tsukasa escaped with Shu, while Joker faced off both Blacks until Baron arrived to aid Joker. They defeated Black RX with a Punish Mash/Rider Kick combo, though Black manages to escape with the help of Amazon and Super-1. The two Showa Riders beat Baron while he protects Joker from a Rider Kick/Great Slice combo.

In another clash between Heisei and Showa sides, Black aids the first six Showa Kamen Riders. Black points that the wish of the Heisei Riders to bring back their fallen comrades is what allowed Badan to attack. However, the Heisei Riders don't back down and Black 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 Kurayami Taishi of the Badan Empire reveals himself to be Ryo Murasame (Kamen Rider ZX). Together, they execute the Showa Riders' plan to restore and bring together the other Riders.

Black RX takes on various Combatroids alongside Shvarian, while Black faces more Combatroids and Baraom. Midway through the battle, they're attacked by the Generalissimo of Badan when he emerges, although Daigo KiryuIcon-crosswiki.png from the KyoryugerIcon-crosswiki.png soon takes the battle. After Shu is rescued by Decade, both Black and RX are among the Riders that attack Badan City directly to destroy the Mega Reverse Machine and Badan's headquarters. After the battle is over, both combine their powers for a Rider Syndrome technique, allowing Shu to meet his mother one last time.

However, there was still one final clash between the Heisei Riders and Showa Riders in order for the Heisei Riders to be acknowledged by the Showa Riders. Black initially faces Hibiki while Black RX faces Blade, when the battle gets to the beach, Black faces Double while Black RX faces Ryuki in a sword battle. Shortly afterwards, Black RX faces Double, while Black faces OOO. After the end of the battle between Gaim and Rider 1, all other Riders stop their own battles and agree to protect the world together.[Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat.

He and his senior Riders, Takeshi Hongo and Shiro Kazami are one of the three main Showa Riders in this movie. He remains BLACK after Shocker alters the timeline into making Kamen Rider 3 exist.

Affected by the timeline being changed from Rider 3 defeating the Double Riders, Kohtaro never evolved from Black to Black RX and remains as Black even into middle adulthood. Althought he fights against Shocker Rider Drive, he is able to help restore Shinnosuke's memory, but later sacrifices his life to allow him and Kiriko to escape the Drive Pit. Kohtaro is revived a while afterwards and evolved from Black to Black RX. During the Rider Grand Prix, he defends Drive from Mashin Chaser while on the Ridoron. In final battle, he joins Shinnosuke and his friends accompanied with most of good Riders to start their final battle against Shocker and their Great Leader with help of a Super Sentai Team Shuriken Sentai NinningerIcon-crosswiki.png.

Saber + Zenkaiger: Superhero Senki

Though he was seemingly erased as a result of Asmodeus’ manipulations, he was restored back into existence once Touma Kamiyama had helped Shotaro regained his passion in drawing out the superheroes that he wants to draw out. Not only that, during the climatic final battle itself, both of his incarnations as Kamen Rider Black and Kamen Rider Black RX had existed as separate individuals while the aforementioned battle had gone underway.

Kamen Rider Black can be seen fighting alongside Red Mask, Ryuu Ranger, Geki Red and Kamen Rider Buster whereas Kamen Rider Black RX can be seen fighting alongside Red Turbo, Bouken Red, Kamen Rider Double and Zenkai Vroon.

Kamen Rider: Battride War Genesis

Kamen Rider Black RX in Battride War Genesis.

Both Black and Black RX are among the Showa Riders who make their Battride War debut in this game. Like both versions of IXA, Nago (the playable/2000s version of IXA) and Otoya (tag partner only/1986 IXA), both versions of Black can be paired if using tag partner mode.

As Black, this form is a charge and trapping character, such as having a Vital Charge refill by holding R1 to use Vital Charge via holding square to gain an access of a powerful version of his special attacks once the power is fully charge, such as from Kingstone Flash to Rider Kick automatically, or as a counter when using Kingstone Flash during guard from enemies' attacks. Vital Charge charges can be perform during an attacks. His only super finisher is from Rider Punch to Rider Kick, which access to Vital Charge state. However, when entering the transportation mode riding his Batta Hopper, even while in "final form" state including when wait too long without riding his bike in that state, Vital Charge state is still limited like in normal state, but can be refill via charging on his Rider Chop and Punch special moves, as using Hold R1/D-Pad Up button will only exit his "final form" state and cost amount of meters.

As Black RX, this form has a form change of becoming Roborider and Biorider. As his default current RX form, he has Sun Bask Resurrection Gauge, which can be accessed after its auto-regenration while in this form then dies at 0% reviving him in 50%. His "final form" is in his default RX form, but has a full access on using all Revolcane slash attacks, such as on his normals. However, unlike Ryuki, RX lacks vehicle changes while changing form, such as Roborider's Roboizer and Biorider's Macjabber, including Ridoron, which should a vehicle transportation for his "final form". Instead, as seen while as Roborider and Biorider when using a transportation ride, he will revert to back his default RX form.

Children's Day 1996

Kamen Rider Black took part in stopping a Shocker plot, where they, the Space Bosozoku Bowzock, Alien Baltan, Alien Pitt, Alien Bado, and the space monsters, Bemstar and Gigan, to take over the Earth. Kamen Rider Black joined the legendary heroes, such as Kamen Rider 1, Ultraman, Carrangers, UltraSeven, Ultraman Taro and even the king of monsters himself, Godzilla to foil their plot.


Kohtaro is humble and sentimental, yet also hot-blooded and tenacious. Before being converted into a Kamen Rider, he would show traits typical for a young person, namely an interest in trends and famous idols. After his 19th birthday though, Kohtaro became burdened with as Black, showing strong signs of anguish in moments of solitude. The pain he felt from losing his loved ones would worsen this, unable to reunite with Kyoko and Katsumi from guilt for failing to save Nobuhiko Akizuki/Shadow Moon.

When given another chance at life by the Sahara family though, Kohtaro's cheerfulness returned. Even when battling against the Crisis Empire, Kohtaro remained optimistic as ever. However, Kohtaro's past still haunts him at times; his worst fear to end up alone once more. This, combined with his lingering guilt can cause Kohtaro to be overprotective, not wishing for anyone else to leave him. Learning to overcome this fear became an essential aspect of Kohtaro's life, with the closure he received regarding Nobuhiko allowing Kohtaro to finally overcome his guilt. Notably, this is fully shown after defeating the Crisis Empire; Kohtaro calmly accepting his friends' departure, knowing that his bonds with each of them would remain forever.

As a running gag, Kohtaro has a sneaky and shameless side, and is not too adept with plants. This is prevalent in both Kamen Rider Black and Kamen Rider Black RX, with Kohtaro accidentally killing a friend's houseplant and attempting to cover it up through deception.

Fighting skill

As Black, Kohtaro's combat style is a combination of physical brawling and use of mystical abilities granted from his Kingstone. Initially lacking in combat experience, Kohtaro struggled to face Gorgom's strongest forces, with Bilgenia and the High Priests of Gorgom being serious threats against him. Yet, through time, Kohtaro gradually became more than capable of facing any threat, to the point of overwhelming an enhanced Shadow Moon in battle, despite Kohtaro's reluctance and Shadow Moon's armament of the Satansaber.

He was also able to pilot a helicopter as shown in RX. After becoming RX, Kohtaro became adept at sword fighting and shooting with precise marksmanship, turning him into an even more formidable Kamen Rider.

Having his body altered and the Kingstone called the "Stone of the Sun" implanted into him, Kohtaro gained the power to transform into Kamen Rider Black, a candidate for the position of Creation King. From his Kingstone and physical enhancements, Kohtaro is immune to several threats such as: mind control, drugs, the Mirror World[3], and time paradoxes[4].

After being ejected into space by the Crisis Empire, Kohtaro's Kingstone evolved giving him the power to use the more powerful and versatile Black RX form. From the mystical powers granted by the Kingstone, Kohtaro is instantly able to adapt in any life-threatening situations he may face, attaining Roborider form[5], Biorider form[6], and even cheating death itself[7].

Kamen Rider Black

Rider Statistics[8][9][10][11]
  • Rider Height: 198.7 cm
  • Rider Weight: 87 kg

Rider Senses:[10]

  • Eyesight: 1 km
  • Hearing: 500 m
Ability Parameters
  • Alert Point (アラートポイント, Arāto Pointo): A red device on the forehead that sends an alert when there are monsters nearby or an incoming attack
  • Multi-Eye (マルチアイ, Maruchi-Ai): His eyes glow allowing him to see monsters' movements in the dark and far away. It can also detect monsters' weaknesses.
  • Sensitive Ears (センシティブイヤー, Senshitibu Iyā): The triangular structures on both sides of his head would glow purple and enhance his hearing to super-human levels.
  • Rider Sensor (ライダーセンサー, Raidā Sensā): Kamen Rider Black's antennaes would move to detect monsters which were moving too fast to be seen.
  • Power Stripes (パワーストライプス, Pawā Sutoraipusu): Black's striped bands on his neck, wrists and ankles would glow to temporarily stores huge energy for final moves. It can also release the power to repel any monsters' sticky fluids or goo on his body.
  • Strengthened Skin - Riplasform (強化皮膚・リプラスフォーム, Kyōka Hifu Ripurasufōmu): The grasshopper-like exoskeleton that protects Kamen Rider Black's body from attack
  • Strengthened Muscle - Filbron (強化筋肉・フィルブローン, Kyōka Kin'niku Firuburōn): As the result of the cyborg surgery, the brown muscles under the Strengthened Skin, gives Kamen Rider Black 30 times the strength of a human.
  • Storage Lung (ストレージラング, Sutorēji Rangu): Compress and store large amount of air, allowing Black to stay in water for more than 10 minutes
Combat Techniques
  • Rider Punch and Rider Kick: The primary killer moves in the entire series were the Rider Punch and Rider Kick which is charged with Kingstone 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.
  • 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.
  • Kingstone Flash: Perhaps the most powerful technique. By shouting out "Kingstone 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.

  • Rider Height: 198.8 cm
  • Rider Weight: 88 kg

Rider Senses:

Ability Parameters

Black RX is the current Kamen Rider form of Kohtaro Minami, a photosynthetic warrior as well as the evolved form of Black, using the sun as his main energy source.

  • Sun Bask (サンバスク, Sanbasuku) - The Sun Bask is a system on the abdomen to collect and store sunlight energy. The transformation belt Sunriser transforms power from the Kingstone and power collected by the Sun Bask into hybrid energy, which gives Black RX more power than Black. The Sun Bask also allow Black RX to recover from injury instantly under sunlight. As sunlight is the 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 Kingstone and sunlight).
  • Psycho-indicator (サイコインジケータ, Saiko-injikēta) - The "third eye" on the forehead which can sense enemies nearby and monsters that transformed to humans.
  • Macro-eye (マクロアイ, Makuro-ai) - More powerful than Black's Multi-eye, having the ability to see objects behind obstacle and inside the enemies' body by reading infrared, ultraviolet and X-ray signals.
  • Solar Radar (ソーラレーダー, Sōra Rēdā) - Black RX's antennas which can locate enemies far away, with higher accuracy than Black's Rider Sensor. They also have the ability to detect weak electric and sound waves.
  • RX Form (RXフォーム, RX Fōmu) - The strengthened skin that protect Black RX from attacks and even 6000°C of heat.
Combat Techniques
  • Revolcrash
  • RX Kick - Unlike Black's Rider Kick, the RX Kick is a double-foot attack which is twice more powerful than Rider Kick.
  • RX Punch - The Black RX version of Rider Punch with twice more power.

Releases the light from Sun Riser

  • Kingstone Flash - Similar to Black, it is used to either daunt or break the illusion of enemies. Kingstone Flash is not always effective against the Crisis Empire. When Black RX performed Kingstone Flash in front of Gedoll Ridoll, It gave the enemy a chance to absorb all the power of the Kingstone. Black RX has another similar trick to disturb the enemies, which is to releases the light from Sun Riser. It can be assumed that this is exactly like Black's Kingstone Flash, but with twice the power.
Appearances: RX Episodes 1-22, Run All Over the World, 23-47 & All Riders vs. Dai-Shocker. Let's Go Kamen Riders, Super Hero Taisen, Kamen Rider Taisen, Super Hero Taisen GP, Kamen Rider Saber + Kikai Sentai Zenkaiger: Superhero Senki

Behind the scenes

Portrayal and Casting

Kohtaro Minami is played by Tetsuo Kurata (倉田 てつを, Kurata Tetsuo). As Kamen Rider Black, his suit actor was Jiro Okamoto (岡元 次郎, Okamoto Jirō) who also did work for RX along with Roborider and Biorider. Other suit actors were Tokio Iwata (岩田 時男, Iwata Tokio), who did Roborider and Biorider, and Toshiyuki Kikuchi (菊地 寿幸, Kikuchi Toshiyuki) who did work for Roborider.

In All Riders vs. Dai-Shocker, Jun Watanabe (渡辺 淳, Watanabe Jun) did suitwork for RX, Roborider, and Biorider 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 TaisenIcon-crosswiki.png, 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 Hiroshi Kamiya (神谷 浩史, Kamiya Hiroshi) and Kenichi Suzumura (鈴村 健一, Suzumura Ken'ichi) respectively.

Rider No.

As the leading Rider protagonist of Kamen Rider Black and Kamen Rider Black RX, Kohtaro 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 Kohtaro Minamis

  • There have been several 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 Kohtaro to meet his past self. He also meets himself in his other forms, Roborider and Biorider, who also arrived due to the 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 universes.
    • 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 Kohtaro 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 Kohtaro 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 Kohtaro 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 Kohtaro 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.
    • The seventh is in the 8ing's Kamen Rider video game series since Climax Heroes series, while pairing both Black and Black RX in the team slots, presumably that both Blacks are from different timelines.
    • A special case occurs in Super Hero Taisen GP: Kamen Rider 3Icon-crosswiki.png, where both Black and Black RX appear, but at separate points in the film, and that they are both the original Kohtaro Minami.
  • According to producer Shinichiro Shirakura, due to many fans prefering Black over Black RX, Toei has decided to treat them as seperate people, starting with Kamen Rider Decade.[16]

Dub names

  • Kohtaro is renamed as Robert Akizuki in the Filipino dub and as Isamu Minami in Brazil. Kamen Rider Black was named "Black Kamen Rider" in the Brazilian-Portuguese dub, with the name "Blackman" used for merchandising purposes. In the Malaysian English dub of Black RX, he is referred to "Black Masked Rider RX".
  • The Filipino dub's transformation call was "Rider Change" and "Mantra Aji" in the Indonesian dub before reverted back to "Henshin" in the RTV airing in 2020.


Concept art for Roborider

Concept art for Biorider

  • Kohtaro is the only Rider to be the leading protagonist of two shows in the Kamen Rider Series. From this, he also has the following holds the record of the Rider with the most appearances.
  • Both Black and RX are paid homage 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, a 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 is the only Rider to have a completely different name in each of his forms (going from Kamen Rider Black RX to just Roborider/Biorider).
  • If overlaying Kamen Rider Black's story with real life events, Kohtaro and Nobuhiko's birth date is most likely September 22, 1968. Having turned 19 years old in 1987, the two were undoubtedly born in 1968, with September 22 being the only date within the year to have a total solar eclipse,
