|This article is about a/an rider in Kamen Rider Black and Kamen Rider Black RX.|
Kohtaro Minami (南 光太郎 Minami Kōtarō), alternatively spelt Kotaro Minami, 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 Kohtaro Minamis who are independently Black and 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 both died (when Kohtaro was around 3 years old) as a result of an apparent accident, Prof. Akizuki then adopted Kohtaro 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. 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 the final brainwashing Soichiro Akizuki interrupted the final stage of the process with Kohtaro barely escaping.
Having been pursued by Gorgom after his escape, Kohtaro 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, 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 organization, Gorgom had him and Kohtaro's mother assassinated. After Prof. Akizuki is killed by five of Gorgom's Spider Mutants, Kohtaro 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, 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 allies in fight against Gorgom, such as Interpol officer Ryusuke Taki and Gorgom's own Whale Mutant.
Eventually Kohtaro reunites with Nobuhiko; however, Nobuhiko was converted into the perfected Century King, Shadow Moon. In their fight, just when Kohtaro was winning the fight, the Creation King temporarily turned Nobuhiko back into human form again. This caused Kohtaro to lose the fight as Nobuhiko turned back into Shadow Moon and launched a surprise attack. He then tried to convince Shadow Moon that Earth belongs to all living things and was landed a finishing blow. As he turned back into human form thus causing Shadow Moon to hesitate and decide against taking Kohtaro's King Stone, Kohtaro 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 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 Satan Sabre used 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 the Gorgom defeated, Kohtaro visited the Capitola bar before leaving for unknown parts.

- ―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 King Stone was damaged and his transformation ability eliminated. He was ejected into space to float aimlessly until the sun's radiation altered his King Stone. 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, Bio Rider. 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, shortly after, Shadow Moon was finally defeated when RX thrust the Revolcane through Shadow Moon's King Stone, seemingly effectively turning him good shortly before he died after saving two kids. With a sorrowful look of sadness as he saw Nobuhiko's corpse, Kohtaro remembered Shadow Moon's actions and decided that in the end, Shadow Moon truly turned back into Nobuhiko as he swore in his heart that he would defeat the Crisis Empire and bucked up his determination. He then carried the now human form Nobuhiko's body to presumably bury him. In the finale, he was helped by the 10 veteran Kamen Riders to destroy the Crisis Empire.
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. The two are joined by RX's alternate forms of Robo Rider and Bio Rider, and the four Kamen Riders combine their powers to defeat the revived monsters.
Kamen Rider Decade
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
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.
Super Hero Taisen
- "Stop this, Nobuhiko!"
"Don't interfere, Black Sun!"
- ―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 Maskman, as they protected Earth in the same year, and launched an attack against the revived Shadow Moon and General Jark.
Super Hero Taisen Z
Black RX was part of a force of Rider and Sentai reinforcements led by Kamen Rider 1 and Akarenger that came to assist the Riders and Sentai of recent years who were overwhelmed by the revived monster army of the Space Crime Syndicate Madou. 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 Psycho 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
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 Ambassador Darkness 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 Schwarian, while Black faces more Combatroids and Baraom. Midway through the battle, they're attacked by the Generalissimo of Badan when he emerges, although Daigo Kiryu from the Kyoryuger 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.
- "We protect the dreams of children, and continue to rain hope for everyone. That’s what it means to be a Kamen Rider!"
- ―Kohtaro Minami reveals the meaning of being a Rider[src]
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 Ninninger.
Chou Super Hero TaisenThe Chou Super Hero Taisen Game World copy of Kamen Rider Black was the red representative and leader of Team Jiro in the tournament for the power of the Kamen Sentai Gorider. They faced Team Takaiwa in their first match, but it's not known who won. Either way, the winner of the match was defeated by Team Genm immediately afterwards.
Kohtaro is an emotional man which has served both good and bad for him. After seemingly losing his step-brother when he became Shadow Moon, Kohtaro tried very hard to get Nobuhiko back while being saddened at having to fight him. He also didn't truly give up on Nobuhiko and tried to save him even as Shadow Moon. Towards the end of his first series, Kohtaro had to part with not only Battle Hopper who thanked him for everything, but also with Shadow Moon who he unwillingly defeated in combat serving as a maturity point for him. As saddened as he was for failing to save the both of them, Kohtaro chose to keep on living for himself showing strength for his character.
It was shown that Kohtaro is a trendy person who is into the latest stuff. As a running gag, Kohtaro has a rough side, and isn't too adept with plants. This goes even further in his second series, as Kohtaro once gave too much water to Reiko's cactus and tried to make it look like someone stole the cactus while secretly throwing it away. This shows a sneaky and shameless side to his personality.
After becoming Kamen Rider Black RX, Kohtaro reunited with his bike who was also revived into Acrobatter, whom he often talks with rather humorously. Also to be noted is that unlike the previous series, Kohtaro seemingly managed to help Nobuhiko regain his former self as he died after saving some kids. The death of Nobuhiko seemed to have strengthened his will as he swore in his heart that he would defeat the Crisis Empire which he eventually did. Interestingly, Kohtaro seems to have become more humorous in RX.
As Black, Kohtaro utilized his power through physical brawling while effectively using his King Stone Flash against his opponents. He was also able to pilot a helicopter as shown in RX. After becoming RX, he has relied more on his weapons and didn't use his King Stone Flash or physical moves as effectively as his previous series hinting a drop in physical skills. He does however, become adept at sword fighting and shooting with precise marksmanship. In his later battles, Kohtaro seems to have regained his physical skills through training with his seniors.

"To be added"
All Kamen Rider: Rider Generation 1 & 2
Kohtaro, as both Black and RX is the unlockable characters on both games. His RoboRider and BioRider forms are used for super move. In the second series, RoboRider can use another technique by increasing the attack power of his Vortech Shooter, while BioRider can use another technique by slashing enemies with his Bioblade.
"To be added"
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 Robo Rider and Bio Rider. 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 Robo Rider's Roboizer and Bio Rider's Mach Jabber, including Ridoron, which should a vehicle transportation for his "final form". Instead, as seen while as Robo Rider and Bio Rider when using a transportation ride, he will revert to back his default RX form.

After being transformed into a cyborg and having the King Stone called the "Stone of the Sun" implanted into him, Kohtaro 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, Kohtaro's King Stone evolved giving him the power to use the more powerful and versatile Black RX form.
In the first episode, Kohtaro briefly transformed into this grasshopper themed monster called the Batta Man (バッタ男 Batta Otoko, Grasshopper Man) before he became Black. He usually transforms into this form first before transitioning into his standard Black battle form.
- Weight: 87kg
- Jump: 30m
- Punch: 15ton
- Kick: 30.5ton
- King Stone - Transformation device
- 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
- 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.
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.

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. His Sunriser has the two pieces of Kohtaro's shattered King Stone. His secondary finishing move is the the RX Kick.
- Sunriser - The Sunriser is Black RX's transformation belt that is actually the King Stone. The King Stone was split in half in response to Black's evolution, and allows for more powerful transformations. The belt design changes in response of Black RX's Form changing.
- Sun Bask - The Sun Bask (サンバスク Sanbasuku) is a system on the abdomen to collect and store sunlight energy. The collected sunlight and the power of the King Stone become the hybrid energy of Black RX. 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 King Stone and sunlight).
- Revolcane - The Revolcane (リボルケイン Riborukien) is Black RX's sword that 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 into the enemy, sending an unlimited surge of energy. However, Black RX has a fatal weakness that when he is generating the Revolcane, the King Stone will become vulnerable.
- Wrist Communicator - the watch-like device on the left wrist of Black RX to call for his vehicles.
- Acrobatter - 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 Kohtaro. Whenever Black RX transforms into any of his two other forms, it does the same.
- Ridoron - High-speed car.
Combat Techniques and Other Body Parts
- 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.
- Marco-Eye - Ability to see objects behind obstacle and inside the enemies' body.
- King Stone Flash - Similar to Black, it is used to either daunt or break the illusion of enemies. King Stone Flash is not always effective against the Crisis Empire. When Black RX performed King Stone Flash in front of Gedoll Ridoll, It give the enemy a chance to absorb all the power of the King Stone. 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 King Stone 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

Robo Rider (ロボライダー Robo Raidā) is a form where Black RX 's armor becomes bulky and more robotic-like, with black and yellow coloring and his Sunriser resembles a gearbox. During his duration as the "Prince of Sadness", both his strength and defense are enhanced. He is also unharmed by explosions or projectile weapons. The only downsides are that he moves slower than Black RX as well as possessing semi-robotic movement, slowing his reaction time.
- Vortech Shooter - Robo Rider's signature weapon is the Vortech Shooter pistol that shoots a powerful energy blast that can destroy an enemy in one blow. According to material, this gun ranges limitless and never misses the target.
- Roboizer - Acrobatter transforms into Roboizer when RX becomes Robo Rider. This form of Acrobatter has two blasters mounted at its rear.

- Jump: 90 m
- Speed: 100 m/ 2 s
Bio Rider (バイオライダー Baio Raidā) is a form where Black RX's armor becomes much sleeker, blue and silver all over and his Sunriser belt resembles a single King Stone one. During his duration as the "Prince of Anger", his speed is enhanced. He can also transform with speed of up to 1000m into gel for escaping traps or attacking enemies while not getting hurt in the process, as he is invincible while in his gel form. Out of it, however, RX sacrifices armor strength, leaving him more vulnerable to powerful attacks.
- Bio Blade - Bio Rider's signature weapon is the unbreakable Bio Blade katana. Like the Revolcane, Bio Blade has also a light saber mode that can slash his enemy in one blow.
- Mach Jabber - Acrobatter transforms into Mach Jabber when RX becomes Bio Rider.

Legend Rider Devices
Kamen Ride Black (カメンライドBlack Kamen Raido Burakku) is the Kamen Ride Card which contains the power of Black. In Black×Black RX, Diend snatches the card from Decade following its awakening in the World of Black RX, claiming that Tsukasa can't use it yet, then used the card to summon the Kohtaro Minami from the World of Black. In All Riders vs. Dai-Shocker, Decade Complete Form Jumbo Formation performed the Final Dimension Kick, a variation of the Dimension Kick, transforming the Shōwa Riders, including Black, and Heisei Riders into Kamen Ride cards for Decade to travel through as opposed to Final Attack Ride cards before hitting the target.
In theory, this card would allow Kamen Rider Decade to transform into Black.
Black Switch (BLACKスイッチ Burakku Suitchi, Triangle): An Astroswitch bearing the likeness of Kamen Rider Black. It is exclusive to Kamen Rider Battle: Ganbaride, where it can be used by Kamen Rider Fourze to arm him with the Black Module (BLACKモジュール Burakku Mojūru) on his left leg, which allows Fourze to use Black's Rider Kick finisher.

Behind the scenes
Portrayal and Casting
Kohtaro Minami is played by Tetsuo Kurata (倉田 てつを Kurata Tetsuo). Kurata auditioned for the role of Kohtaro 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 Kohtaro 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 Kohtaro Minami/Kamen Rider Black in Kamen Rider: Seigi No Keifu. In 2009, Kurata returned as Kohtaro 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 Kohtaro 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 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.
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.
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, Robo Rider and Bio Rider, 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 3, where both Black and Black RX appear, but at separate points in the film, and that they are both the original Kohtaro Minami.
- Kohtaro is renamed as Robert Akizuki in the Filipino dub and as Isamu Minami in Brazil.
- Kohtaro 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:
- Kohtaro currently holds the record of the Rider with the most appearances.
- Kohtaro 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.
- This is debatable though, as RX`s powers seem to have all of Black`s powers plus more.
- As Black RX's Bio Rider form, Kohtaro 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.
- Kohtaro's Robo Rider form is hampered by stilted, robotic movements. In rare instances however, Robo Rider is able to move unhindered, due to the need to move or act quickly.
- 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.
- Kohtaro is the only Rider to get a new name upon Form Changing (going from Kamen Rider Black RX to just Robo Rider/Bio Rider). Unlike most Riders that would proceed him, Kohtaro does not need to perform a transformation pose or rely on a gadget to change forms, allowing him to change between Rider forms at a moment's notice.
- Black RX accessing his weapon through his belt would later be replicated with Kamen Riders Agito, and Ghost.
- Since Kohtaro managed to defeat Shadow Moon, that would technically mean he is the next Creation King albeit without Shadow Moon's King Stone.
- Kohtaro's and Nobuhiko's birthdate is most likely September 22, 1968 - as they turn 19 in the first episode of BLACK, which takes place in 1987, it's sure that they were born in 1968. In that year there was only one Solar eclipse, which was a total one and took place on September 22.
