History of Kuroto Dan/Kamen Rider Genm from Kamen Rider Ex-Aid.
Origin[]
At 14 years old, Kuroto was a game developer for the Genm Corp and created numerous successful games. While he was developing a game one day, Kuroto discovered a mysterious glitch that emerged from the Y2K bug and showed it to his father, the CEO of Genm Corp, Masamune Dan. This glitch would then take shape as the Bugster Virus.
One day, Kuroto received a fan mail from Emu Hojo suggesting a new idea for a game. Though impressed, Kuroto was angered that someone else was as talented as him and thus he sent him a game called Mighty Action C that contained the Bugster Virus. When Emu played it, he became infected with the virus.
Zero Day[]
In 2010, Kuroto hired the Next Genome Institute to abduct Emu after the Bugster virus within him fully matured, with Kuroto having secretly observed the virus' development for the past decade.
With the virus now in his hands, Kuroto used it to trigger Zero Day, where the Bugsters emerged from the glitches of 10 games produced by the Genm Corp. In collaboration with the Ministry of Health, Kuroto designed the Gashats and Gamer Driver to counter the Bugsters. He gave a Gamer Drive and the Proto Bang Bang Shooting Gashat to Taiga Hanaya, a doctor from the CR, so he could become the first doctor rider to combat the Bugster virus. However, Kuroto was secretly using Taiga to finalize the Gashat. The effects of the Gashat on Taiga later caused his defeat at the hands of Graphite, resulting in him leaving the CR.
Kuroto managed to avoid punishment for the outbreak by framing his father Masamune Dan for it. With his father out of the way, Kuroto became CEO of Genm Corp. While the truth remained under wraps for some time, two years after Zero Day, Kuroto was confronted by Kiriya Kujo, a coroner who had discovered the truth about Zero Day after his friend Jungo was infected by the Bugster virus and died in an accident. In exchange for his silence, Kuroto gave Kiriya a Gamer Driver and the Bakusou Bike Gashat.
Kamen Rider Ex-Aid[]
A second Bugsters outbreak occurs following the release of Genm Corp's new game, Mighty Action X. Unbeknownst to everyone, Kuroto is secretly collaborating with the Bugsters, needing their help to develop his ultimate masterpiece, Kamen Rider Chronicle, a game where people in the real world will be forced to fight against Bugsters for his amusement.
Dan first appears at the press release for Mighty Action X, where the Salty Bugster emerges from Sota Suyama. After Salty is defeated by Kamen Rider Ex-Aid, Dan calls Poppy Pipopapo and tells her to record Emu's specs as the Action Gamer using his specialized VR for later use.
While acting as an ally to the CR, Dan secretly menaces them as the mysterious "Black Ex-Aid"; first appearing as the Rider when Kamen Riders Ex-Aid and Brave are fighting the Alhambra Bugster. Genm attacks the two, giving the Bugster time to flee the scene. Later on, Kuroto Dan is approached again by Taiga Hanaya, who brings a new Driver and Bang Bang Shooting Gashat from Kuroto with a large pile of cash. This sale causes Hiiro Kagami to confront Kuroto about selling a Driver to a doctor who had his medical license revoked but Kuroto defends his decision by saying that Taiga is both compatible and capable.
After Taiga takes Emu's Gashat, Kuroto comes to CR later to apologize for giving Taiga a Driver again and assures Hiiro that there will be more Gashats ready within a few days. Later on, Kuroto as Kamen Rider Genm interferes in Brave and Snipe's fight to deplete their Rider Gauges. After Ex-Aid and Lazer defeat the Motors Bugster, Genm finishes off the Bugster to prevent Lazer from getting a sample to study. Genm then uses the Shakariki SportsGashat to upgrade to Sports Action Gamer Level 3, which he uses to defeat Ex-Aid and Lazer with one move.
Kuroto Dan calls Poppy Pipopapo to tell her that the newly-developed Gashats were all stolen by a hooded man and also secretly informs Taiga and Kiriya, giving them the special stethoscope. He later comes to the CR and asks Emu if he knows who Kamen Rider Genm really is, with Asuna stating that the thief is Genm. After Emu gets in a fight with Hiiro, Dan goes to comfort Emu in private at a helipad and tells Emu that it's only natural for a doctor to have a desire to save the patient, but that he agrees with Hiiro, since the man is responsible for the stolen Gashat. He then compares Emu to a crystal which, once shattered by a malicious patient, couldn't shine again. However, to Dan's surprise, Emu says that he'll regret the day he can't save a patient and leaves. Deciding to teach Emu a lesson, Dan, transforms into Kamen Rider Genm Sports Action Gamer Level 3, and Robots Collabos attack and beat down Kamen Riders Brave Quest Gamer Level 2 and Lazer Bike Gamer Level 1. As Emu questions Genm as to why he attacked the doctors, the thief appears and Genm directs Emu to him, with the thief later being revealed to be Graphite.
Genm then lectures Emu that his idealism doesn't work on a real battlefield and that survival is only for the strongest. Angered by Genm's remarks, Emu transforms into Kamen Rider Ex-Aid Action Gamer Level 2 and defeats the Robots Collabos using Mighty Critical Finish before shifting to Robot Action Gamer Level 3 and beating Genm with the Gekitotsu Critical Strike, causing Genm to retreat. Canceling his transformation, Dan meets with Graphite and Parado. Graphite asks Kuroto if he was afraid of Emu, but Dan psychotically proclaims that his genius is the only thing to be feared.
As Emu and Hiiro are attempting to extract the Collabos Bugsters that had infected Yoshio Okada, Kamen Rider Genm enters the scene and fights off both Emu and Hiiro as Sports Gamer Level 3 to give the Bugsters an opportunity to escape. Afterwards as Brave is fighting the Chambara Collabos Bugster, Genm intervenes again to fight the Rider, buying Emu and Kiriya time to obtain the Giri Giri ChambaraGashat. His identity exposed, Genm then fights Kiriya as the now Chambara Bike Gamer Level 3 and is defeated by Lazer's Giri Giri Critical Finish. However, Parado then appears and creates a protective barrier to allow Dan to escape before pretending to have been the Black Ex-Aid to fool Emu and Hiiro, causing them to lose trust in Kiriya. Back at his office, Kuroto has his Gamer Driver and Proto-Mighty Action X Gashat returned to him by Parado.
Kuroto is later warned by Parado that while the Proto Gashats have great potential, prolonged usage will damage his body. Right after, Dan receives a call from Kiriya Kujo and meets him under a bridge the next day. Kuroto denies knowing anything about Parado to Kiriya before transforming into Genm Sports Action Gamer Level 3 to fight Kiriya as Kamen Rider Lazer Chambara Bike Gamer Level 3. However, the two prove evenly matched and are unable to gain an advantage over the other. Kiriya then asks Kuroto why he is on the side of the Bugsters, to which Dan states that he is working with them to figure out why they came into their world and that that is the reason why he developed the Gamer Drivers and Rider Gashats. He then states that one has to undergo a compatibility surgery in order to use the Gamer Drivers and hints to Kiriya that one of the Doctor Riders has not received the compatibility surgery. Upon hearing this, Kiriya quickly identifies the Rider as Emu Hojo.
Meeting with Parado in his office, Kuroto informs him that he had Graphite take the Proto Drago Knight Hunter Z so he could give the Kamen Riders their most challenging fight yet as he went on a rampage, causing Parado to jokingly state that Dan had scared him. Kuroto then went to CR to show Drago Knight Hunter Z to Emu and Hiiro, which he states is the key to defeating Graphite. Dan informs the two that Drago Knight Hunter Z need to be completed by defeating the Hunter Gamer and warn them that Drago Knight Hunter Z is a 4 Player co-op game and require teamwork to avoid the danger of using it alone. In spite of Dan's warning however, Emu took the Gashat for himself and stayed he would clear the game. Watching from afar, Dan and Parado observed Emu as he initially failed to convince his fellow Riders to cooperate. Dan assured Parado that they would collect their data either way and that they can eventually replace the troublesome doctors with new candidates. Eventually though, Emu and his fellow Doctor Riders are able to collaborate by dividing and using the Hunter Gamer together to terminate Graphite. After Graphite's destruction the Proto Drago Knight Hunter Z is recovered by Parado, Dan allowing Dan to use it to complete tests and data recording so they can to move on to the next stage.
Kuroto Reveals Himself[]
Revealing himself as Kamen Rider Genm to the other Riders, Dan taunts them with the fact that a large amount of people are infected with the Bugster Virus and that a break-out can happen at any moment. He then proceeds to say to the Doctor Riders that it is up to them whether the people with the ten Gashats will be saved or not before using the Gashacon Bugvisor to make his escape. Returning to his office, Dan reveals Dangerous Zombie, the newest Gashat he had created.
Kuroto later learns that Kiriya has met with his father and is planning to tell the other Riders what he had learned. Before Kiriya can meet with the other Doctor Riders to reveal Dan tracked Kiriya down and offers him the Dangerous Zombie Gashat supposedly in exchange for Kiriya's silence. As Dan had intended, Kiriya takes Dangerous Zombie and when Kiriya attempts to use it, he is instead severely weakened. Dan took the Gashat back and used it to become Kamen Rider Genm Zombie Gamer Level X. Genm then takes the Giri Giri Chanbara Gashat as well and, just moments before CR and Snipe arrive, mortally injures Lazer.
Ex-Aid Double Action Gamer[]
As the "test players" are no longer needed, Dan decides it is time to take back all the Gashats from the Doctor Riders. While Kamen Riders Ex-Aid and Brave are fighting the Level 3 Alhambra Bugster, Kamen Rider Genm appears to confront them and summons the Gashacon Sparrow for himself to use. Upon seeing Kiriya's weapon, Ex-Aid becomes enraged and, assuming Hunter Action Gamer Level 5 Full Dragon, strikes Genm with the full force of his power, only for Genm to quickly recover in a cloud of purple smoke. Revealing that his Rider Gauge is stuck at zero, Dan declares that he has surpassed death with no attack being able to slow him down. In spite of this, Ex-Aid continues to fight against Genm until Genm triggers the Critical Dead and sends a horde of shadowy zombie figures to eliminate Ex-Aid. Right as the zombies explode however, Brave tackles Ex-Aid out of the way and cancels both of their transformations to remove the Game Area so they can escape.
At his hideout, Dan presents to Parado a blank, double Gashat he had created for him to use; informing Parado that it will need to be inserted into a Bugster to obtain data to finish it and that a human who uses it will die instantly from a massive Bugster virus infection. As Snipe and Brave face Alhambra, Genm joins the fight and quickly defeats both Riders but, before he can kill them, Genm is confronted by Emu holding the blank double Gashat he had given to Parado. Emu attempts to used the Gashat but is overwhelmed by the Bugster virus. However, rather than succumb to the virus, Emu is somehow able to transform the blank Gashat into a new game, Mighty Brothers XX, shocking Genm. Transforming into Double Action Gamer Level X, Kamen Rider Ex-Aid manages to stand up to Genm with his new powers. Ex-Aid then advances up to Level XX and is split into two separate Level 2-shaped Riders.
However, the split also divides Emu into two distinct individuals. While the two Ex-Aids conflict with one another, Genm uses the distraction to escape with Alhambra. Back at his hideout, Dan speaks with Parado about the new Gashat Emu had created, which Dan declares to be a bootleg and states he will erase it.
As the Level 2 Action Gamer, Kamen Rider Genm fights and defeats the familiar Emu. Declaring himself the Game Master once again, Kuroto demanded the new game be deleted. However, Emu then transforms into Ex-Aid Double Action Gamer Level XX again and fights Genm and Alhambra. Achieving a perfect co-op, the two Ex-Aids are able to destroy Aranbura, whose data is promptly salvaged by Genm with the Gashacon Bugvisor used by Genm. Telling Ex-Aid fate is out of his control, Genm makes his leave.
After Revol re-emerges as a Level 5 from Nico Saiba, Dan transforms into Kamen Rider Genm Zombie Gamer and face Emu again, intent on deleting the data of Mighty Brothers XX. After fighting Ex-Aid for a short while, Genm opts to instead escape with Revol rather than continue fighting. Soon after, Kuroto is confronted by Taiga, who reveals he knows that Kuroto had killed Kiriya to cover up how Emu has Game Disease. Kuroto then reveals that Emu is the first person to ever be infected with the Bugster virus and that it has spread and caused Zero Day six years ago after the Next Genome Institute extracted it. Before leaving, Kuroto tells Taiga that he only killed Kiriya because he intends to use this information to destroy the Bugsters. Returning to his hideout, Dan deduces from viewing recorded battle data that each side of Ex-Aid's Level XX (20) form has the power of Level X (10). He then gives a new Gashat he had created to Parado, who is excited to use it to have fun in his first battle.
When Parado returns to his hideout after easily defeating all three Doctor Riders, Dan criticizes him for not bringing Emu's Gashats with him. Parado simply responded that he is only helping Kuroto so he can play Kamen Rider Chronicle and Dan agrees to let Parado defeat Ex-Aid his own way. After Revol returns, Dan transforms into Kamen Rider Genm Zombie Gamer to take Ex-Aid and Brave's Gashats himself. By initiating a Critical Dead before the two Riders can Level Up, Genm is able to defeat both Riders and cancel their transformations. After taking the Taddle Quest and DoReMiFa Beat Gashats from Hiiro, Dan goes to steal Emu's Gashats but is stopped when Emu emits a surge of Game Disease. Parado then arrives and tells Genm not to attack Ex-Aid before they both leave. Later on, Dan shows up whilst Parado is fighting Ex-Aid to take Snipe's Gashats. Nico attempts to fend him off with a mop, but Genm swiftly shoves her aside. Snipe attempts to take down Genm with a Drago Knight Critical Strike, but Genm is not slowed down by the attack. After Kamen Rider Para-DX destroys Revol Bugster as punishment for interrupting his "fun", Genm quickly collects Revol's data in the Gashacon Bugvisor, annoyed with Para-DX's decision to destroy the Bugster before leaving with Para-DX.
Burgermon Incident[]
Dan is informed by Parado of a new Bugster who had come from Ju Ju Burger, a game which Tsukuru Koboshi developed in Dan's absence that was dropped from the Genm Corp.'s line-up. Initiating a Stage Select, Dan and Parado confront Emu and the Burgermon Bugster. After assuming their Rider forms, Kamen Riders Genm and Para-DX fight Kamen Riders Ex-Aid and Snipe to recover the Ju Ju Burger Gashat from the Riders. After Para-DX defeats both Riders, Dan triggers a Critical Dead and sends it to terminate both Tsukuru and Burgermon. However, Burgermon takes the full brunt of the attack, sacrificing himself to save his creator. Though Dan could have saved the Bugster's data, he does not because he is an "illegal Bugster." Emu then rages at Genm for his cruel action but quickly collapses. Genm taunts Emu by suggesting that something within him is making him favor Bugsters before leaving with Para-DX and returning to their hideout. Parado asks Kuroto why he terminated the Bugster, to which Dan responds that by saying that while Ju Ju Burger belonged to him, the Bugster within is a bootleg.
Falling Out with Parado[]
Dan proclaiming himself as god to Paradox.
Seeking to claim Snipe's Gashats next, Kuroto infects Tsukuru with the Motors Bugster to lure out Emu and Taiga. After distracting Kamen Rider Ex-Aid by triggering an outbreak to upgrade Motors, Genm defeats Snipe and takes back the three Gashats. With the games he has taken, Dan is able to create a new Level 50 Gashat. When Parado insists that he be the one to beat Emu, Dan warns the Bugster not to talk back to the "Game Master" and went on a rant where he claimed both the Gashats and Bugsters are nothing but tools in his master plan and declares that, as the Game Master, he is God. Later on, when Ex-Aid shows up to stop Motor's rampage, Dan appears and reveals his new creation, Gashat Gear Dual β. Using the Fantasy Gamer from the Taddle Fantasy side, Dan defeats Ex-Aid with one hit. Disposing of the now-useless Motors, Genm demands Emu turn over his Gashats and threatens to kill him if he refuses. Para-DX then arrives to confront Genm, having grown tired of his narcissistic egotism and disregard for the Bugsters. Declaring Parado a worthless game character, the two began fighting in a battle that ends with Kuroto being brutally defeated. To spite Parado for acting out against him, Dan attempts to rob the former of his wish to fight Emu and reveals to Emu that he is the patient zero of the Bugster virus, laughing psychotically as Emu begins to be overwhelmed by the virus.
However, instead of disappearing Emu faints from the stress. Fleeing to his hideout, Dan eventually confronts Ex-Aid again when the next outbreak occurs. Whilst managing overpower the Rider at first, the tide of the battle turns when Hiiro intervenes, causing Genm to lose three Gashats, including the Gashat Gear Dual β.
Completing Kamen Rider Chronicle[]
Dan later meets with Parado again in his office, still hostile to him after their last encounter. Following this, Kuroto stage selects with Vernier Bugster, Emu, and Poppy in a deserted valley and transforms into Kamen Rider Genm to kill them both. However, Taiga then arrives, armed with the Gashat he "took" from Hiiro at the abandoned hospital. While Kamen Rider Snipe Simulation Gamer Level 50 takes on Vernier, Emu uses the Mighty Brothers XX Gashat to face off against Genm. After absorbing Vernier's data, Kuroto leaves and returns to his hideout, where Parado was waiting for him to finish Kamen Rider Chronicle. Kuroto then reveals to Parado that the reason that he chose Dangerous Zombie as his Gashat is because it's not only Level 10 but also Level X, the undetermined variable.
Observing Kamen Riders Ex-Aid and Brave fight the Kaiden Bugster, Genm goes to battle against Kamen Rider Snipe Level 50 but is defeated. Returning to his office, Kuroto reveals that he needs one more piece of death data from a Bugster to access Level X. Kuroto then confronts Emu and Asuna after Masamune Dan reveals to them that Kuroto was the true cause of Zero Day. Kuroto laughs at them and admits that he pinned the blame for it on his father. When Emu learns that Kaiden is out again, Kuroto faces off against Emu as the two transform and fight while Taiga and Hiiro take on Parado and Kaiden. As Hiiro defeats Kaiden with the Drago Knight Hunter Z Gashat, Ex-Aid defeats Genm. Absorbing the data from Kaiden's demise, Kuroto gloats that both the Bugsters and Kamen Riders are pieces in "the ultimate game" and reveals to them the Kamen Rider Chronicle, in which civilians will transform into Kamen Riders to do battle with Bugsters. Emu expresses disgust at Kuroto for his twisted game idea and for how so many people including Kiriya, Saki Momose and Uesegi's son have died because of him before using the Mighty Brothers XX Gashat and the Gashacon Key Slasher to defeat Genm, causing Genm to disappear.
As Kuroto observes that only three more Bugsters, Doremifa Beat, Shakariki Sports and Drago Knight Hunter Z, are needed to complete Kamen Rider Chronicle, the Ministry of Health closes in on his hideout. To evade being incarcerated, Kuroto infects himself with the Bugster Virus, turning himself into the Charlie Bugster. After being defeated by the Doctor Riders, Dan pretends to express remorse for his actions and convinces Emu to take him to the Seito University Hospital to be treated. While there, Kuroto reveals to Emu that he was the one who infected him with the Bugster virus 16 years ago because Emu came up with a better idea for a game than him, seemingly apologizing and expressing regret for his actions. However, after the Charlie Bugster is destroyed by Ex-Aid, Kuroto absorbs its data into the Gashacon Bugvisor and reveals that he was just acting in order to collect the rest of the data he needed to complete the Kamen Rider Chronicle. Dan then transforms into Kamen Rider Genm and beats down Emu before going to the Genm Corp building and returning to his office.
Death[]
Kuroto attempts to infect every civilian with the Bugster Virus of DoReMiFa Beat and Drago Knight Hunter Z in order to complete the Kamen Rider Chronicle. However, before Kuroto can complete his diabolical plan, Emu creates the Maximum Mighty X Gashat and transforms into Kamen Rider Ex-Aid Maximum Gamer Level 99. With the new power from his level upgrade, Kamen Rider Ex-Aid, alongside Brave and Snipe, are able to finally defeat Genm Level X. To stop the Zombie Rider, Ex-Aid uses Maximum Gamer's reprogramming ability to delete the Bugster Virus antibody sample in Kuroto's DNA, revoking his ability to transform into his Rider form. Emu then attempts to take Kuroto into custody instead of killing him, only for Parado to then appear. Parado at first appears to assist Kuroto but instead knocks him to the ground and steals his Gashacon Bugvisor, with which he uses to infect Kuroto with the Dangerous Zombie Gashat, filling him with both lethal amounts of the Bugster Virus and countless data of his own death. As Parado declares that Kamen Rider Chronicle now belongs to him, Kuroto psychotically proclaims that he is god and that his ambitions will go on forever before dying and disintegrating from his "Game Over".

Though brought back as a Bugster, Kuroto is gleeful that he had achieved immortality. Kuroto then transforms into Genm Level 0 and heads to the Next Genome Institute to get revenge on Parado. He attacks Parado just as he is about to finish off Emu, saving the heroic Rider in the process. Kuroto later attempts to threaten the doctor Riders once they are back at CR, but Poppy absorbs him back into the Bugvisor II.

Kuroto later discovers that Poppy sacrificed herself to cure Super Gamedeus' horde. A distraught Kuroto is comforted by Poppy who tells him not to cause trouble and to keep making games before fading.
As Zombie Action Gamer, Kuroto fights alongside Ex-Aid and the other Riders against Super Gamedeus.

However, Cronus is then overpowered by Ex-Aid, who reveals that Cronus had been weakened by Parado's sacrifice. Switching to Level 0, Kuroto joins the other Riders in fighting Cronus and together they are able to defeat him. In one last act of spite, Masamune kills himself to prevent any of the Game Disease victims from being revived.
Aftermath[]
Kuroto later manages to revive Poppy from the sample of her virus that he had absorbed into his hand. He also reveals to Emu that he has been infected with a fragment of Parado, which is why he can still transform into Ex Aid. Parado then returns from within Emu right after.

Kamen Rider Zi-O[]
King Kuroto Dan.
Kuroto Dan appears as the antagonist of the Kamen Rider OOO tribute arc, where he is given the Another OOO by the Time Jackers after they observe his lust for power. Using the watch, Kuroto transforms into Another OOO and kills off his father Masamune Dan, allowing him to assume control of their company the Dan Foundation. Kuroto then leads the company into becoming a successful megacorporation within two years. Kuroto Dan holds a press conference where he announces that Dan Foundation will rule as its own sovereign nation independent from Japan with him as King and that all of their properties will become their own national territory where the laws of Japan become null and void. A member of the National Diet rejects Kuroto's rule, but Kuroto tosses a Cell Medal on him, transforming him into a Waste Yummy.
After they rescue civilians from Waste Yummies, Sougo, Geiz and Tsukuyomi meet Kuroto Dan who transforms into Another OOO to attack them. Before he can do so, the Taka Watchroid suddenly shows up out from nowhere and attacks Another OOO. The Genm Ridewatch drops from Another OOO while Tsukuyomi glances at Another OOO's year number at the back, which she initially perceives 2016. Kuroto Dan then flees his castle, but Sougo decides to pursue him. After examining the Genm Ridewatch, Geiz and Tsukuyomi travel to the year 2016 in order to confront Another OOO. Geiz uses the Genm Ridewatch to become Geiz Genm Armor and defeat Another OOO, but his efforts prove futile as Another OOO revived soon after. Tsukuyomi then realizes that Another OOO was not created in 2016 but in 2010.
Back in 2018, Kuroto decides that the motif of his next royal garb will be based on a zombie. His costume designer, Hina Izumi, then questions his rule. Applauding her boldness, Kuroto tries to take her as his queen, but she refuses. Angered over her objections, Kuroto brutally assaults Hina but is interrupted by Sougo. Sougo informs Kuroto of his own ambitions to become King, leading to Kuroto appointing Sougo as one of his loyal retainers. After observing Zi-O's battle with Geiz, Kuroto promotes Sougo to captain of the royal guard and orders his Yummy servants to imprison Hina in the same room as the Diet member he captured, who turns out to be Eiji Hino.
Eiji and Hina later enter Kuroto's office, where Eiji tells Kuroto he will stop him no matter what. However, Kuroto finds Eiji's defiance amusing and asks him if he believes if it is worth risking his own life for. Eiji responds that as long as people are suffering under Kuroto's reign he will not rest until he has defeated him. Just then Sougo enters the room and asks Kuroto what kind of country he seeks to create as king, as well as why his subjects regard him as evil. Kuroto states that he desires to conquer all of Japan and rule over it as Supreme Kuro-king Dan, proclaiming he will make all of Japan's citizens bow to him. Eiji then states that no person has the right to take people's freedom but Kuroto tells him he already has because he is a king. Kuroto then orders his Waste Yummies to eliminate Eiji and Hina, but Sougo steps in and captures Eiji instead, asking Kuroto to leave Eiji to him. Kuroto agrees and walks off to another area of his castle.
However, Sougo is revealed to have simply pretended to be loyal to Kuroto in order to discover what kind of king he was. Kuroto eventually discovers Sougo's treachery when he discovers him untying Eiji and Hina. As Kuroto expresses disappointment at Sougo's betrayal Sougo asks Kuroto if he ever thought about reaching out to his subjects. However, Kuroto finds the idea disgusting and proclaims that his subjects are lowly filth that should never lay a hand on him. Repulsed by Kuroto's elitism, Sougo prepares to transform to fight Kuroto, but Kuroto becomes Another OOO first and attacks him before he can become Zi-O, knocking his Zi-O Ridewatch from his hand. Kuroto then prepares to finish him off but Eiji interferes alongside Hina is able to knock back Another OOO. Eiji then helps Sougo up and gives him his OOO TaToBa and Tajadol Ridewatches, before Sougo goes outside to confront Kuroto.
Kuroto later confronts Sougo again outside. Sougo changes into Zi-O to face off against Kuroto, but their fight to be interrupted by Ora piloting a Time Mazine of Castle Doran. Geiz then appears and transforms into Geiz GenmArmor to fight the Doran Time Mazine while Zi-O heads to 2010 to confront Kuroto after he obtained the OOO Anotherwatch. After equipping his OOOArmor, Sougo overpowers Kuroto's Another Rider form, declaring that who becomes king is not Kuroto's choice but the choice of the people, before finishing off Kuroto's Another Rider form with the Scanning Time Break. Upon his defeat Kuroto freaks out and is thanked by Woz for being "good fertilizer" for the path of Zi-O to become ruler of the world. Kuroto then passes out from exhaustion.
Kamen Rider Genms -The Presidents-[]
Part 1[]
Kuroto reawakened by the Ark.
Following his seeming demise, Kuroto is able to survive by backing his data up and us later found by the AI of the Ark, which reawakens him so he can infect Gai Amatsu.
After Gai comes down with a mysterious fatigue and suddenly collapses, Kuroto Dan emerges from his body and reveals that Gai is infected with the Bugster Virus. Kuroto explains to Gai that the more stressed he becomes, the more Kuroto will gain a physical body until Gai finally perishes and Kuroto regains his physical form. Upon discovering that Gai is a fellow company President, Kuroto recounts how he once served as president of Genm Corp. and created countless amazing games with his "godly talents". Declaring himself a superior company president to Gai, Kuroto kidnaps his Humagear secretary Rin and fled the building.
Kuroto brings Rin to a lakeside, where he examines her and comments how impressed he was by the technology of Humagears, stating that AI technology has progressed a lot. He exclaims to Rin that he could teach far more than Gai, and that with his talents she will be capable of becoming a goddess but Rin rebutts Gai's offer as she just wants to be returned to Gai.
Genm VS Thouser
Gai then appears and Kuroto announces that they will duel for possession of Rin and pulled out his Gamer Driver to transform. Gai transforms into Kamen Rider Thouser, only to find his Rider form has changed to black (similar to Kamen Rider ZAIA). Kuroto explains that that is due to him being infected and that black is his own personal color, before transforming into Kamen Rider Genm Level 2 with his own Driver. The two Riders then fight, with Genm gaining the upper hand and defeating Thouser. After Genm knocked Gai out of his transformation, he prepares to finish him off with his Rider Kick, only for time to suddenly pause before his kick can land. The source of the pause is then revealed to be his father Masamune Dan, who then steps out to greet his son.
Part 2[]
Masamune knocks Kuroto away before transforming into Kamen Rider Cronus to battle him. Genm then asks how Masamune returned, to which Masamune responds by posing the same question to him. As the two Riders clash, Kuroto declares that he will recreate Genm Corp with himself as president, but Masamune states that Genm Corp is his and that he will defeat Kuroto. Kuroto then insists that he should be president as he loves games more than Masamune did, but Masamune proclaims that he has more love for the company and its staff. Genm and Cronus then trad a mutual finishing kick that de-morphs both. It is then Gai that approaches; having realised that "love" is what is most important when making a company after seeing the two Riders quarrel. Hearing Gai's words, Kuroto and Masamune embrace and reconcile before returning to the digital world thanks to Gai conquering his stress.
Within the digital world, Kuroto declares that he will use "love" to change the coming era into an ending befitting him before letting out a maniacal laugh.
Kamen Rider Genms -The Smart Brain and the 1000% Crisis-[]
Gai Amatsu and Rin later work with the Ark to summon Kuroto again by giving him a HumaGear body to possess, in order to get his help in stopping Zein. Their initial attempt inadvertently summons Ren Amagasaki, who believes himself to be the one they are looking for since he is also a president of Genm Corp., but Kuroto soon appears and casts him away before possessing the HumaGear body. Before Gai can explain why he summoned Kuroto however, Kuroto runs off in his new HumaGear body to reestablish the Genm Corp. After testing out his new body's capabilities in a nearby park, Kuroto soon realizes he is running out of power and ran around frantically looking for a charger. Right before shutting off, Kuroto pulls out a picture of his father and asks him to give him strength.
However, Kuroto is rescued by Rin, who brings him to a charging station and refills his power supply before explaining why they summoned Kuroto. A new AI called Zein with a zero tolerance for malice has surfaced on the Internet and that they fear it will attempt to destroy humanity in order to eradicate malice. Kuroto however is not concerned with this and only desires to recreate Genm Corp. He challenges Gai to a duel, saying he will help Gai if Gai manages to defeat him, but that he will gain his Thouser-Intellion building to reestablish Genm Corp with if he wins. Gai agrees to the terms of the deal and uses the Ark-Driver the Ark had given him to transform into Kamen Rider Thousand-Ark, while Kuroto in turn transforms into Kamen Rider Genm. With the power of the Ark, Thousand-Ark is able to defeat Genm, only for Kuroto to suddenly pull out the Bugvisor and use it to extract data on the Ark from Thousand-Ark. With this data, Kuroto quickly creates the Musou Gamer Gashat and uses it to transform into Kamen Rider Genm Musou Gamer. In his new form, Kuroto is able to defeat Thousand-Ark. Despite being beaten, Gai expresses awe and amusement at Kuroto, remarking he is a very interesting man. Kuroto then leaves to claim the Thouser-Intellion building as his. As he enters it, he is observed by a woman from Smart Brain, who notifies an unseen figure via phone that she found Kuroto.
Kamen Rider Ex-Aid: ~Mighty Novel X~[]
Kuroto Dan tricks Emu Hojo into playing a new Gashat he created called "Mighty Novel X", causing Emu to be trapped inside it. Throughout, Kuroto mostly acts through a backup of his data he created through God Maximum Mighty X called "Kuroto Dan II". Through getting Emu to play the new Gashat, Kuroto will be resurrected upon Emu's completion of it, though at the cost of Emu's life since Mighty Novel X is based on Emu's life and he will die once he reaches the end of it.
It is revealed that Emu's father Kiyonaga Hojo played a part in the emergence of the Bugster virus, as it was his simulation calculations on the Y2K virus that caused it to emerge. Kiyonaga partners with Masamune Dan to develop medical equipment capable of combating the virus, but Masamune and Kuroto end up blackmailing Kiyonaga with the information that he is responsible for the virus. Kiyonaga is forced by Kuroto to turn over his son to the Next Genome Institute so they can separate the virus from him.
After hearing all of this, Emu becomes extremely agitated and angered but suddenly Kuroto's body reverts into a human form, dressed in his villain self. Kuroto reveals that his plan to anger Emu was part of his plan to resurrect himself, and calls himself Dan Kuroto II. Emu asks Kuroto why he was absent for three years. Kuroto replies that, at the press conference where Emu addresses the victims of Kamen Rider Chronicle and Zero Day, upon hearing his name, knew he was given a three-year grace period. After wandering around on his own, he knew it was finally time to be back. He then mocks Emu's capability of becoming a doctor.
Upon completing Mighty Novel X, Kuroto Dan will be fully resurrected. Kuroto and Kiyonaga Hojo met, revealing that they had stored the Bugster Virus in medical equipment developed by companies across the country. Zero Day will have an imminent relapse, and there is only one way to stop it, and that is for Emu to end his life by completing Mighty Novel X. Frustrated and wanting to end things, Emu grabs the Gamer Driver used by Kagenari Nagumo. Emu waits for Kuroto at a park near the hospital, as he is given the opportunity and location to determine the future of Mighty Novel X, Kuroto must appear as well. Emu finally meets Kuroto, who has already transformed into Action Gamer Level 2. Emu transforms into Action Gamer Level 2 and the both of them engage in a series of fights. Emu who has fought against Kuroto many times realizes that he is not actually fighting him.
"Kuroto" transfigures, and reveals himself to be Kiyonaga. The real Kuroto Dan II appears, due to Kiyonaga halting the continuation of the game. Kuroto then uses the Bugvisor II to eliminate Kiyonaga. Kuroto and Emu finally fight, transforming into Genm and Ex-Aid Action Gamer Level 2s. The two Gamer Riders used Energy Items in the Game World to fight fiercely, After a while, both riders were seemingly unscathed, but Genm uses the last of the energy items, causing the ground to eject magma, resulting in a violent attack. Ex-Aid responds by using various energy items, and a randomizing energy item. The randomizing effect is "reversal", and causes the magma attack to rebound on Genm, causing more damage. Close to victory, Genm unplugs Ex-Aid's Maximum Mighty X, leaving him unable to transform into Hyper Muteki.
Genm transforms into God Maximum Gamer Level Billion and launches a cosmic chronicle at Mars, crashing it on Ex-Aid. Thought to have suffered a heavy damage, Ex-Aid emerges unharmed, in his Level 2 form. He proclaims that, with invincibility, it would be nearly impossible to suffer a defeat at the hands of others, but one should never underestimate someone else's powers. It could take five years, ten years or even a lifetime to complete the game, but everyone has a time limit.
Emu takes out the Mighty Novel X Gashat and attempts to transform, but to no avail. It turns out, that the Gashat does not work on the Gamer Driver as it does not carry a game function, and the ability to Level Up. In a last-ditch effort, Emu combines with Parado, merging Parado's virus into his own genetic genes, reversing it onto the Gashat, successfully activating it. Emu transforms into Novel Action Gamer X. Statistically, Ex-Aid’s Level X is weaker than Genm’s Level Billion, but the Novel Gamer has the ability to overwrite reality, such as implementing his own speech to determine the damage received from Genm’s attacks such as, "Your attack won't hit me", "Eat my attack" and "I feel pain". Gaining the upper hand, Ex-Aid finishes Genm with a Novel Critical Destiny. Suffering defeat at the hands of Emu, Kuroto disintegrates into thin air.
At the CR, Emu promises to treat Kuroto back to health, depending on the future to decide Kuroto's eventual return. Kuroto is revealed to be alive, dwelling in the world of the Proto Mighty Action X Origin Gashat. There, after his memories merge with memories of Kurotopi, he talks about Emu, learning about his self-sacrificing fearless attitude, as well as his new form. He remarks that the form's ability to predict the future simulates his talents and will be used in future game creations.
Kamen Rider Outsiders[]
Episode 0[]
Having taken over Thouser-Intellion's headquarters, Kuroto establishes the "Musou" Genm Corporation inside the building and begins working to acquire other companies in order to grow Musou Genm Corp into an all-encompassing empire. To finance his new Genm Corp, Kuroto uses the Musou Gamer Gashat to select winning lottery tickets and scratches them out to obtain the money.
Musou Genm Corp is be threatened by a resurgent Smart Brain corporation, led by a now fully-healed Arch Orphnoch, who attempts a hostile takeover of Musou Genm Corp in order to obtain Kuroto's Musou Gamer Gashat. Smart Queen go to retrieve the Gashat but Kuroto refuses to hand it over. After running out of power for his Humagear body, Kuroto is found by Mari Sonoda and brought to a charging station. He initially acts hostile to her and believes her to be Smart Queen, but Mari tells him that Smart Brain stole her look. Mari explains to Kuroto Smart Brain's goals of supplanting humanity with Orphnochs in order to persuade him to help her stop them, and Kuroto agrees to oppose them because they targeted him first.
Smart Queen then transforms into Kamen Rider Delta and attacks Kuroto in order to obtain the Musou Gamer Gashat from him. Although Smart Queen was able to fight evenly with Genm Musou Gamer and came close to defeating him with her finisher, Kuroto was able to use the Gashat's power to stop time before Smart Queen could finish him off and used his finisher on her in order to defeat her. After Smart Queen crumbles to dust, Mari runs in and the Arch Orphnoch also arrives. Gai Amatsu and Rin then step in and attempt to persuade Kuroto and the Arch Orphnoch to team up to oppose the Zein AI, but both vow to defeat it on their own terms and refuse to join together.
