Genm Corp.

    Kuroto Dan/Kamen Rider Genm 

Kuroto Dan/Kamen Rider Genm

Played by Tetsuya Iwanaga, Satoshi Fujita (Level 1 suit), Yuya Nawata (Level 2 suit)

"I am the Game Master, and I am God!"
The CEO of Genm Corporation. 5 years ago, his company worked on a new brand of video games. However, the games were corrupted in such a way that they gave birth to the Bugsters. After the monsters went on a rampage, he created both CR and the Kamen Rider systems in cooperation with the Ministry of Health in order to correct his mistake. However, all this was a lie. His true intention is to create the ultimate game, Kamen Rider Chronicle, using the real world as its stage.

Kuroto first discovered the Bugster Virus while working as a game designer in the year 2000, and soon after would be contacted by a young Emu with ideas for a new game. Incensed by the discovery that Emu's talents as a game designer matched his own, he sent back a disk containing an prototype Mighty Action game which was laced with the new virus, using Emu as an incubator for ten years until having the mature virus harvested by Michihiko Zaizen in 2010. In 2011 Kuroto would use the matured virus to enact Zero Day, framing his own father for the event and taking control over Genm Corp. After seemingly killed by Parado, he returns as the Bugster of Proto Mighty Action X Origin, comically renaming himself "Shin (Neo) Kuroto Dan" to celebrate his return. And again as "Kuroto Dan Shin (God)" in the finale. But reverted back to "Kuroto Dan" in Kamen Rider Genm vs. Lazer before seemingly dying.

For tropes related to his appearance in Kamen Rider Zi-O, please see his entries on the character pages here and here.


  • A God Am I: Being a genius creator of most games in his company, as well as the Rider System and its Gashats, Kuroto boastfully claimed that he's a god to the point of seeing others as nothing but a bunch of lowly sinners and he still carry this habit after his Hazy Feel Turn. Taken Up to Eleven in Another Ending.
  • Admiring the Abomination: He's insanely pleased with himself when Gamedeus finally emerges in sharp contrast to his ambivalence towards all the other Bugsters he created who aren't Poppy.
  • Alas, Poor Villain: Not that he didn't deserve it, but Parado coldly (but still understandably) injecting enough of the virus to give him an agonizing Game Over? Ouch. Emu seems to think so, while the others were at least stunned from seeing it right in front of them. Kuroto does return later, but it's the end of him as a villain.
  • Ambiguous Situation: His "death" at the conclusion of the Another Ending Trilogy is deliberately vague as he simply vanishes without the GAME OVER title card when he ultimately runs out of lives and Kiriya is haunted by a vision of him when he visits the place he supposedly died.
  • Ambition Is Evil: And how. All the things he did come from his desire to create better games and smother all possible competition. It's eventually subverted to a degree in that his ambition is a little more humane than it first appears: to revive his mother.
  • Armor-Piercing Question: Talking about anything to do with his mother prompts him to deflect immediately to talking about his own genius in an obviously forced manner.
  • Asshole Victim: Kuroto had it coming since the day he turned Emu into Patient Zero. Kiriya must be laughing his ass off in the afterlife for that. And if he wasn't, he got to kill him himself the second time in the Gorider miniseries.
  • Ate His Gun: To prevent Parado and Poppy from taking it away from him, Kuroto aims the Bugvisor II holding Another Parado's data into his mouth and fires the information directly into his body during the ending of Kamen Rider Para-DX with Poppy.
  • Back from the Dead: Many, many times. If deaths that only last a few seconds are counted, Kuroto's total resurrection count is in the two-digit range. Even just counting main deaths, he had three separate contingency plans to revive himself at various points in the show and side material.
  • Badass in a Nice Suit: He's always impeccably dressed in a suit.
  • Beneath the Mask: A calm and polite exterior hides the raving megalomaniac within.
  • Berserk Button: A few. The easiest is to create a Gashat, as he does not consider imitation to be flattering and stops at nothing to take away the "bootleg" Gashats he learns of. Parado eventually earns a particularly personal dose of hatred as well for his backstabbing.
  • Big Bad: While others eventually usurp the role, Kuroto remains the origin of most of the main cast's woes, as nearly everything bad about their lives stems from his actions and the Bugster virus as we know it wouldn't exist had he not turned Emu into Patient Zero in an act of petty spite. He later resumes the main antagonist role for real in Another Ending.
  • Bitch in Sheep's Clothing: He initially presents himself as his father's penitent successor, eager to atone for Masamune accidentally instigating Zero Day. It goes without saying that he's anything but sorry, let alone innocent.
  • Blue and Orange Morality: He doesn't consider instigating Zero Day to have been something worth apologizing for, as everyone who dies from Game Disease just gets digitized and stored in the Proto Gashats. Nevermind that aside from all the destruction and grief caused by Bugster attacks, he's basically keeping all those people prisoner (including his mother) while making it so that the only way to free them is to complete Kamen Rider Chronicle, a video game that is nigh-unbeatable. Notably, Kuroto made sure that this process wouldn't apply to him if he ever succumbed to the virus, as his data would be stored in a private Proto Mighty Action X Origin Gashat.
  • Boxed Crook: Essentially his position after his resurrection as a Bugster. While the Doctor Riders need him due to Level 0's power, they're fully aware he's as evil as ever and Poppy has him on a short leash thanks to being able to trap him in her Buggle Driver II any time she pleases.
  • Breakout Character: Kuroto's immense popularity with the fans led to him being the center of the Another Ending trilogy of post-series specials. Not to mentioned that he is one of the characters who received a SH Figuarts toy release based on his human identity twice.
  • Came Back Strong: While after his resurrection he loses several of the advantages he once had as a villain, the revival does come with Bugster teleportation powers and the useful debug functions of the Proto Mighty Action X Origin Gashat.
  • Came Back Wrong: One interpretation of Kuroto's Sanity Slippage is that it's tied to his frequent deaths and revivals with the power of Dangerous Zombie, which often happens multiple times in one fight. That said, Kuroto had scenes suggesting he was out of his mind well before he created that Gashat, and all that happens is he becomes progressively more comfortable with abandoning the mask of sanity he once wore.
  • Catchphrase: After his revival, he adopts an Ironic Echo of Emu's as his own: "I'll clear this, even with Continues."
  • Chewing the Scenery: After his true colors shine through, Kuroto starts devouring the scenery wholesale. This even proves a weakness as his insane hamminess leads to him explaining Hyper Muteki for so long his invincibility wears off and Masamune steals it.
  • Corporate-Sponsored Superhero: Played with. He takes his Kamen Rider name from his own company and was originally the villainous CEO of said company. But even after his Hazy Feel Turn, he still keeps the name even when he's fighting against his old company.
  • Corrupt Corporate Executive: Having stolen Genm Corporation from his own father, he was one even before he started creating Bugsters, although it might not have gone over so well if Masamune hadn't wanted it to happen.
  • Crazy-Prepared: Arguably one of his biggest strengths. The entire plot of the Kamen Sentai Gorider miniseries is a contingency plan he put in place to resurrect himself in the event of his death. Bonus points for creating this plan when he was presently immortal. Then in the series proper it's revealed he had a contingency plan for his contingency plan. In addition, when Masamune uses his Reset ability to erase Hyper Muteki from existence, it turns out that Kuroto has a contingency plan for it. Not only he successfully recreated Hyper Muteki (at the cost of twelve of his lives due to exhaustion and immense stress), but he also created an Energy Item to prevent Reset's effect from happening to them again.
  • Create Your Own Hero: Emu could only become Ex-Aid in the first place because Kuroto made him into Patient Zero.
  • Cruel and Unusual Death: His second major death comes from being infected by a massive amount of Bugster Virus by Parado, writhing and screaming in pain all the while until his body disappears completely.
  • Curb-Stomp Battle: Because he's Unskilled, but Strong, almost every fight Kuroto is in is a curbstomp on either the giving or receiving end depending on the level gap between himself and his opponents.
  • Cut Lex Luthor a Check: He's got plenty of money from all his ideas already, but there have been a few times where his ego seems to get in the way of taking an opportunity to help his company, such as using Taiga's bribe money to turn the world into his personal battlefield instead of aiding with development, or instead of using a young Emu's game ideas, buying the rights, and crediting him for some good PR, deciding to give the kid the Bugster Virus. Then again, he probably knows that his ultimate goal isn't exactly something that he could achieve with enough money or through legitimate business.
  • Death by Irony: His second and third deaths are packed with it:
    • His second death comes from the same weapon he used to infect hundreds of victims, loaded with the Gashat whose power to cheat death he abused countless times and whose toxic effect on the living he used to poison Kiriya to make him easy prey. The death was delivered by the Bugster that Kuroto created himself to infect Emu, and in so doing Kuroto became the Disc-One Final Boss of Parado's schemes much as Kuroto used Parado's friend Graphite to play a similar role.
    • His third death in the Gorider miniseries has him meet his end at the hands of the little boy he infected with the Bugster Virus years ago all grown up, his own murder victim, three other Riders he dragged into his resurrection plot to torment and torture, and the man whose identity he stole.
  • Death Is Cheap: As one might expect from a zombie, Kuroto dies many times throughout the show, including three separate "real" deaths. Several episodes have him die multiple times in a row, reviving through the abilities of one of his Gashats.
  • Defiant to the End: Such is Kuroto's determination to cling to life that no death sees him go gentle:
    • During his second death, even when he loses the ability to use Gashats he still doesn't acknowledge that he has lost to the Riders. Then, when he's about to disappear thanks to Parado infecting him with a massive amount of Bugster Virus, he still has the gall to claim that he is god and that his work will live on forever, completely unrepentant to the end.
    • When he's dying for the third time in Gorider, he makes one last attempt at Taking You with Me, while struggling until his demise against four other Kamen Riders pushing him back at the same time, after taking a ton of punishment.
  • Deader Than Dead: Returns as a Virtual Ghost in the Gorider miniseries, and gets killed again by being dragged into his own black hole, while fighting four other Riders, while the Game World is being deleted. Subverted in that even after this he still managed to return back to life.
  • Devour the Dragon: At the end of Another Ending: Para-DX with Poppy, he absorbs Another Parado's debris into a Bugvisor and then injects the data into himself so he can have the same Bugster virus power as Emu and create God Maximum Mighty X with it. He even injects it into himself through the mouth, literally devouring it.
  • Did Not Think This Through: His Fatal Flaw. He really doesn't think of the long term consequences of his actions nor exact details of his plans. It eventually bites him in the ass every time in more or less spectacular ways:
    • In the Gorider miniseries, he got Kenzaki roped into his scheme among other Riders and copied his Undead powers and form to deceive the others into giving him the despair from the crushed hope of being revived. Once he's been revealed, he discards the powers, thinking them to be useless now. Unfortunately, the Battle Royale's rules said that should the last Undead left be the Joker, the world would end. In the real world, this isn't a problem, since Chalice is still unsealed, but since in the Game World, the only Undead left is Kenzaki, the entire world collapses.
    • He manages to pull another resurrection by using the Proto Mighty Action X Origin Gashat and Poppy's human memories to get her to revive him, but this came at the cost of turning him into a Bugster, allowing him to be sealed in the Buggle Driver II.
    • When he uses Hyper Muteki to become immune to Cronus' time stopping ability, he boasts about how he's invincible… and apparently forgets about the 10-second time limit that promptly ends, allowing Cronus to just pause time again and steal the Gashat while he's at it.
  • Dirty Coward: Without his Resurrective Immortality, he's just an unbelievably petty bastard with delusional fantasies of being "God". When Parado shows up to kill him, all he can say is "I don't want to die!". There are times that he's willing to show some guts, at one point using twenty-four of his continues to hold the line against Masamune at a critical moment, but he remains willing to cut and run where other Riders would stand and fight. He's just being cautious over "player advantages", not because he's cowardly at this point.
  • Disc-One Final Boss: Is the driving force and main villain for the first half of the series, but is defeated by Emu and killed by Parado at around the halfway point. Fitting, given the video game theme.
  • Driven by Envy: His fury at there being someone else out there who was as good at designing games as himself was what led him to use Emu as an incubator for the Bugster Virus.
  • Emergency Transformation: His first contingency plan in the event of his death in Gorider would have brought him back as himself, but when that failed, his remaining scheme involved being resurrected as a Bugster which has its own set of unique drawbacks.
  • Enemy Mine:
    • After his resurrection, he teams up with the Doctor Riders to get revenge on Parado for backstabbing him, something that's made him hate Parado even more so than he hates the doctors. That, and Poppy has him on a short leash. He later stays with them after Masamune makes himself known to get revenge on him for manipulating him and stealing his Evil Plan.
    • Deconstructed ultimately: the fact Kuroto isn't really invested in the heroes' overall goal of stopping "Kamen Rider Chronicle" and instead just wants to get revenge on various people means he never helps as much as he could, only as much as he needs to for his current goals. The stand out example is him revealing he could've made a Cheat Code to get them to the final stage of "Kamen Rider Chronicle" in, by his own admission, five minutes if he'd felt like it, but never said a word about it until it was in his best interests to do so.
    • Once Parado makes a Heel–Face Turn thanks to Emu and joins their team, even being at CR, Kuroto does nothing to him in spite of his original reason for switching sides is to exact revenge on the Bugster. It helps that episodes prior, he and the cast learn that Parado is vital to Emu's ability to transform, so, as much as he wants to, he can't do anything to Parado lest they lose their lone advantage against Cronus.
    • Further deconstructed come Another Ending: since his reasons for siding with the heroes were ultimately self serving, and once he's the last villain standing, nothing is really stopping him from being the "last boss" of his new game as he hasn't changed much if at all.
  • Even Bad Men Love Their Mamas: So much so that he intentionally infected his terminally ill mother with Game Disease so he could convert her being into data and store her in a Proto Gashat as a way of keeping her alive, if only just.
    • Even Evil Has Loved Ones: This extends to his relationship with Poppy, the Bugster that spawned from his mother. After she sacrifices herself to dispel the Gamedeus virus pandemic across the city, he sheds tears over her demise, even as he masks it with his ego.
  • Even Evil Has Standards: As horrible of a human being as he is, even he considers his father a terrible parent and knows his actions are anything but fatherly. Granted, that's because he was the one being mistreated, but given Poppy became his Morality Pet in part by seeing him as her father, it seems to be at least partially genuine disgust on his part.
  • Evil Cannot Comprehend Good: In the Gorider special, he simply can't comprehend why the dead Riders would kill him again despite it meaning they go back to the afterlife as well. Makes sense, given how terrified of death Genm himself was.
  • Eviler Than Thou: While the Bugsters, Parado included, have villainous aims, even they find themselves repulsed by Kuroto's vile behavior. It's eventually flipped around, as Parado reveals his darker aims while Kuroto is cast in a more favorable light following his resurrection.
  • Evil Is Hammy: Once he reveals his true colors, Kuroto's level of scenery chewing steadily escalates to truly outstanding heights.
  • Evil Is Not a Toy: Parado gets pissed when he reveals he was just using the Bugsters and proceeds to beat the crap out of him in response. When he's finally lost the ability to fight the Riders on even ground, Parado kills him to show that he really had little control over him to begin with.
  • Evil Is Petty: When they're not to further his plans, Kuroto's actions are to satisfy his ego, and his ego is very easily bruised:
    • The reason he killed Burgermon was because Burgermon did not emerge from a game he created, since in his mind, only he's allowed to create Gashats.
    • He reveals Emu's Patient Zero status, which he believes will cause Emu to disappear from the stress, purely to punish Parado for defying him.
    • He chose Emu to be patient zero in the first place, under the guise of sending him a game demo, because Emu sent him fanmail with fanmade characters and ideas as a kid and Kuroto was outraged that they were just as good as his ideas.
  • Evil Knock Off: His scheme in Kamen Rider Ex-Aid Trilogy: Another Ending essentially boils down to spoofing Emu's biology so he can replicate the powers typically unique to him.
  • Evil Laugh: At times, as expected from a mad programmer.
  • Explaining Your Power to the Enemy: After using Hyper Muteki for the first time, he does this to boast to Cronus about his invincibility. It backfires, since Hyper Muteki has a 10-second time limit, so he ended up wasting his invincibility talking and letting Cronus steal the Gashat when time's up.
  • Expository Hairstyle Change: Slicks back his hair at the end of episode 22, and maintains it during his final stand in the following episode. He reverts back to his usual style afterward.
  • Expy: Cast in the same mold as Ryoma Sengoku for being an insane genius with narcissistic personalities, great skill at manipulating others, aspirations to godhood, and a powerful Rider form connected to the hero's own. His plans for Kamen Rider Chronicle, meanwhile, draw comparisons to a previous series about a Rider War.
  • Famous Last Words: "I am God! My dreams... ARE IMMORTAAAAAAL!!"
  • Faux Affably Evil: Quite capable of flipping from jovial and dignified to raving lunatic in the blink of an eye.
  • Freudian Excuse: Yes, he's a narcissistic Evil Is Petty Jerkass. Yes, he's a sociopathic Insufferable Genius. Yes, he's a sadistic Killer Game Master. But his villainy comes from the motivation of saving his sick mother. He might have also just inherited it from his father.
  • Genius Bruiser: Is as powerful as any Rider, but also a genuine genius who can program more or less anything into existence if given the time.
  • Goroawase Number: Similar to game developer Suda51, Kuroto has a fondness for using the numbers 9-6-10 (ku-ro-to) as a visual shorthand for his first name. This quirk leads to his undoing in Gorider, when Emu uses the abbreviation to leave himself a clue as to who the mastermind behind the events of the mini-series is.
  • Green Lantern Ring: With the Game Disease code he pilfered from the Millennium Bug, there's very little that Kuroto can't do with his advanced programming skills. Absurdly Sharp Blade? He can make one. Explosive rapid-fire munitions? Easily manifested. High-speed vehicles? He can make you into one. Time-Manipulation? Near-Unbeatable Monsters? A cartridge that can summon forth and imprison the souls of the dead to use their despair to bring someone back to life? Flawless mimicry of magical powers of divine origin? IMMORTALITY? All within his means. In fact, his only real limitations lie in how he needs a lot of data and time to craft his Gashats, but sufficiently motivated and equipped, he can complete them much, much faster. Case in point, he created the Hyper Muteki Gashat, a device that grants complete invincibility (depending on the user) in just a few days. And then when Masamune used Reset to remove it from existence, he was able to remake it from scratch from pure memory in hours, taking from the beginning of sunset to the sunrise of the next day at the cost of a few lives.
  • Half-Human Hybrid: As the Mighty Action X Origin Bugster, he retains a copy of his human DNA and thus can use the Gamer Driver just like Parado can.
  • Harmful Healing: After discovering Game Disease, he sought a way to use its unique interactions with living organisms to turn the biological into the digital to "save" his terminally-ill mother and potentially himself so that he would no longer have to fear death. After he got the science down on how to turn humans into beings made out of data, he used this procedure to cause all sorts of bedlam to help construct Kamen Rider Chronicle with no thoughts spared for potential casualties since anyone "killed" by the disease or the Bugsters would just wind up stored in the Proto Gashats.
  • Hate Sink: After he reveals himself to the Riders, it's gradually revealed that this guy was really good at covering up his utterly despicable actions, from when he infected a young Emu with Game Disease out of his ego being bruised to when he caused Zero Day, and the deaths of thousands of people in the process. Even before the aforementioned deeds were revealed, he continued to go nuts abusing his power to satisfy a petty ego, from murdering Burgermon to infecting his creator so he could rub it in his face. After his revival from his death at the hands of Parado, he stops having hate poured on him and takes a (slightly) more sympathetic bent.
  • He Knows Too Much: His reason for killing Kiriya.
  • Heads I Win, Tails You Lose:
    • His Thanatos Gambit in Episode 11 basically falls under this. Either he kills the young patient and gets his data on death, or he dies and gets the data on death anyway. Either way, he gets to keep on living thanks to the Dangerous Zombie Gashat. He also needed all 10 games to be cleared and Ex-Aid's attack on him did just that by clearing the last game, Shakariki Sports.
    • His overall plan falls into this. Should the Bugster he unleashes defeat the Riders, then he has one less thing to worry about and collects their Gashats back. Should they defeat the Bugster instead, he just collects its data. Either way, Kamen Rider Chronicle gets one step closer to completion.
    • Ultimately inverted, as he never could have won. Poppy already existed, and Graphite could've been revived at any time, so no Bugsters from DoReMiFa Beat or Drago Knight Hunter Z would spawn no matter how many people he infected. His efforts were doomed to failure before they even began.
  • Hazy Feel Turn: Following his second resurrection, Kuroto joins the doctors as their new Sixth Ranger, and while still a narcissist, he takes on a more heroic bent in his actions. A Hero with an F in Good, sure, but that's how three-quarters of the main cast started out. It's still hard to tell if he's genuinely more heroic but won't admit it to himself, or the same old egomaniac whose interests happen to align with the doctors' for the moment. After everything is taken care of, he's back to his old tricks again, this time as the game master of the "last game". Although it's less him going back to being a villain and more him taking an entirely warped approach to heroism.
  • Hero with an F in Good: After he's forced to ally with the protagonists in the second half of the show. Demonstrated to full effect in Another Ending. He's not turned complete villain so much as he is approaching being the hero in am aboslutely terrible way. He's set up a game where clones of Zombie Gamer run rampant. They're at least as powerful as Level 10 but if you can defeat them it will revive someone who died due to the Bugster outbreak (but as a Bugster themselves). He's personally convinced this is the absolute best way to save the people who were lost while demonstrating his continued Godhood. He seems to genuinely believe he's doing the right thing (and rages at his father for not even attempting to revive his mother). So when he can't find anyone taking up arms against the Zombie Gamers, he assumes that people are just so beneath him they can't comprehend the opportunity he's offering them. It never hits him that the weakest Bugster virus is much stronger than a normal human...and minimum his clones are 10 levels higher than that. There are exactly 8 people, including himself and Cronos, that could actually beat one in a fight...and they're not exactly set up to wipe out a zombie apocalypse.
  • Heroic Comedic Sociopath: As Shin Kuroto Dan. He's still a megalomaniacal madman with delusions of godhood and the show milks that for a lot of humor.
  • Hidden Agenda Villain: Bits and pieces of Kuroto's end goal are gradually teased out over the first twenty episodes: to create the ultimate Survival Sandbox game, Kamen Rider Chronicle, as his twisted idea of entertaining people by making them fight against Bugsters for his amusement… except that's not the whole story. The main reason why Kuroto wanted to create Kamen Rider Chronicle in the first place is because of his dying mother, so his endgame, while vile in nature, is well-meaning.
  • Hoist by His Own Petard:
    • Creating the Gashat Gear Duals. The first allows Parado to defy him and even beat the tar out of him with no practical way for Kuroto to punish him for his disobedience, since Parado is Level 50 while Kuroto is stuck at Level 10. The Gear Dual Beta, on the other hand, was created for Kuroto's own use but soon falls into Hiiro and Taiga's hands, allowing them to start reclaiming the Gashats that Kuroto had just spent the past few weeks stealing away from them. Eventually it comes out that Kuroto in fact knew exactly what he was doing, and allowed himself to be killed repeatedly by stronger opponents in order to complete Dangerous Zombie's ascension to Level X. In a Double Subversion, he made two mistakes after all: the first was recruiting Emu as a Rider, as Emu was able to create the Maximum Mighty X Gashat that led to his downfall. The second was trusting Parado. Going even further back: Emu would never have been able to become Ex-Aid and defeat him at all if he'd not infected him with the Bugster Virus in a fit of rage when he was a kid.
    • His contingency plan to resurrect himself in the event of his death would've went off perfectly...if he hadn't chosen Kenzaki's form to be his avatar, which drew the real Kenzaki into the game, which results in Kenzaki, a Joker Undead, being the last Undead present in the Game World, destroying it and foiling Dan's entire plan.
    • Creating Cronus becomes a really big one for him. Designed by Kuroto as someone who can fight and defeat Gamedeus, he made it ridiculously overpowered but ridiculously difficult to acquire, demanding a truly dedicated Ride Player willing to spend over a decade playing Kamen Rider Chronicle just to have a chance at unlocking it. Kuroto definitely didn't expect that his own father would managed to acquire the immunity needed to be able to tranform into Cronus and hijack it's power to further his own plans.
  • Hope Crusher: One of Kuroto's M.O.'s in order to increase the stress from his Bugster infectees, and a means of fueling his revival attempt in Gorider. He later drops this following his resurrection and subsequent Revenge on Parado.
  • Humans Are the Real Monsters: The Bugsters are no saints, but they at least have understandable motives for their actions. Kuroto's just an egomaniac, and will go out of his way to make people suffer. Eventually it comes out that Kuroto had his own Freudian Excuse, but this doesn't temper his narcissism at all.
  • Humiliation Conga: Episode 23 is one long string of Kuroto's advantages and schemes unraveling one after another.
  • Hypocrite:
    • Kuroto claims to want the JuJu Burger Gashat destroyed, even using this as justification for killing Burgermon. However, once he has it, he claims that the idea for JuJu Burger was his in the first place, so the Gashat belongs to him now and thus he doesn't delete it.
    • He is enraged whenever somebody other than himself creates a gashat, referring to them as bootleg games and insisting on deleting them. One such example is Emu's Maximum Mighty X gashat. In Another Ending, Kuroto creates a God Maximum Mighty X gashat for himself that is essentially a ripoff of Emu's.
  • I Have Your Wife: The Zero Day epidemic was basically a mass-kidnapping scheme. All the people who died of Game Disease that day (and those that perished of it afterwards) were to be used as incentives to get people to play Kamen Rider Chronicle after it was completed in hopes of rescuing their loved ones.
  • I Lied: At the end of Para-DX with Poppy, he confirms that his allying with the heroes was just because they had a common enemy and not a Heel–Face Turn on his part, as well as coldly shunning his Dragon, Saiko Yaotome, to whom he made a promise that he would resurrect her father.
  • Immortals Fear Death: Makes it quite clear from his reaction to being stripped of his immortality that he's decidedly afraid of death. He was also so paranoid of dying that even after becoming immortal, he still made two contingency plans to resurrect him in the event he died. That said, it's not just his own death that he's afraid of.
  • Insistent Terminology: He prefers that the other Riders address him with the prefix shinnote  before his name after he was revived as a Bugster. He's not Kuroto Dan, he's Shin Kuroto Dan! It doubles as a punnote .
    • And after completing Doctor Mighty XX, he insists on shin being affixed to his name as a suffix. This essentially changes his name to Dan Kuroto-shin, or Dan Kuroto God.
  • Insufferable Genius: A certifiably brilliant inventor who ally and enemy alike can barely stand due to his massive ego.
  • Irony: He used to store the defeated Bugsters' data into his Gashacon Bugvisor. When Poppy resurrected him, because he's now a Bugster, he now can be stored inside Poppy's Gashacon Bugvisor II anytime she wants.
  • It's All About Me: The only things he cares about are his own desires and goals. His rant in episode 18 sums it up in a way that shows just how goddamn unhinged he is.
    • Episode 22 takes it even further by showing that his Start of Darkness was caused by him receiving fanmail from Emu detailing a few game ideas and characters that he realized were just as good as his own. In response, he engineered the events that would cause Emu to become the Bugster Virus' Patient Zero. That said, he did have one person he actually cared about: his mother, and because she was Poppy's host, he has at least some compassion for her by extension.
    • During Kamen Sentai Gorider he was willing to completely destroy the barrier between the human and Game World (which would have caused a horde of mindless Bugsters to flood the Earth) just to bring himself back to life.
  • It's Personal: Part of Kuroto's alliance with the doctors, as he's royally pissed off at Parado's treachery by the time they met again.
  • Karmic Death:
    • Is defeated by Emu using his murder victim's Gamer Driver. Kuroto is then killed off by Parado with his own Buggle Driver and Gashat he used to kill Kiriya.
    • His death in the Gorider special comes at the hands of the Riders he abused and tormented to resurrect himself, including Kiriya who he killed the first time.
    • After he comes back with 99 lives, the vast majority of those lives are killed off by Kiriya as well.
  • Kick the Dog: While he's got a plan he's fairly good at sticking to, there are more than a few times where he'll just be an asshole to other people because he feels like it.
  • Killer Game Master: Although he proclaimed to be the Game Master, he is prone on killing any obstacles in his sights. It makes the creation of any Gashats that he didn't design a major Berserk Button.
  • Lack of Empathy: If he cares for anyone who's not him, he certainly doesn't show it... well, except for Poppy.
  • Large Ham: As a villain, Kuroto is prone to chewing the scenery in grandiose speeches usually centered around his godly abilities. As an Anti-Hero, this is dialed Up to Eleven with his becoming the almost exclusive source of hamminess and comic relief in the series]].
  • Laser-Guided Karma:
    • He sent Emu, who was a little kid at the time, a Bugster virus infected game in a fit of narcissistic rage over Emu being as good at game design as him. Emu growing up to become a gigantic thorn in his side and ultimately handing him his final defeat is basically very long overdo karma for that horrible act coming back to bite him.
    • Also fittingly enough, he is the second rider to die after Kiriya. They both overpowered by their opponents in term of level and brutality and killed when they are powerless.
    • He also caused a conflict between Ghost and Ex-Aid just because they look similar. How fitting he loses one of his lives over a mistaken identity by Build.
  • The Last Dance: The Another Ending trilogy is Kuroto's, with him ultimately realising that the only way to bring about the return of all the people he imprisoned in the Proto Gashats is to perform a Heroic Sacrifice. Which he ultimately does...after arranging events so that he'd be able to beat on all the heroes and villains who got in his way during the events of the show before making his exit.
  • Licked by the Dog: By Poppy. Notably, she's the only Bugster he's created who doesn't completely hate his guts.
  • Like Father, Unlike Son: While both Kuroto and his dad are psychos, the former is a Crazy-Prepared Insufferable Genius and a borderline Well-Intentioned Extremist who used Kamen Rider Chronicle as a means to preserve data of those who are "killed" by him or succumbed to the Game Disease and is understandably pissed off over someone else hijacking his original plan, while the latter is an out-and-out psychopath who wants to Take Over the World with the aforementioned game and is not above using underhanded methods for unbelievably selfish reasons.
  • Limit Break: Parodied in Heisei Generations FINAL where after his transformation shorts out near the end of a fight, he's forced to use the Kamen Rider Build Gashat with the Gashacon Breaker to finish off the last Nebula Bugster in the area and does so by inelegantly whacking it over a dozen times in a cartoony fashion.
  • Love Redeems: Familial love. After Poppy admits that she sees Kuroto as her father, he begins to form a sense of empathy. Since Poppy's existence has something to do with Kuroto's mother, it makes sense. Ultimately subverted come Another Ending, where he makes it clear that he doesn't care about any of them and was using all of them for his own goals.
  • Manipulative Bastard: Generally a very good judge of character, and uses it extensively to manipulate the other Riders and even some of the Bugsters. Episode 15 presents a prime example, in which he admits to Kiriya's discovery of the incident six years ago, and even describes the event to Taiga. When Taiga calls Kuroto out on explaining something that he killed Kiriya to cover up, Kuroto claims that his reason for killing Kiriya was the latter's desire to destroy the Bugsters, something that Taiga isn't particularly concerned with. This explanation not only caused Taiga and Hiiro to become more concerned in removing the Game Disease inside Emu, but it also covered up the much more important thing that Kiriya discovered, which was about Kuroto and Emu's first meeting sixteen years ago.
  • Mask of Sanity: Normally either a Reasonable Authority Figure, Affably Evil, or The Stoic, at times Kuroto's mask slips to expose the mania worthy of a slasher villain underneath. The mask slips more and more frequently once he's outed as the villain.
  • Meaningful Name:
    • One meaning of Kuroto is "expert" or "professional", which certainly fits him, what with being a CEO and expert game designer. Somewhat comically, one meaning of Dan is "stage", so when said as it would be in Japanese (last name first), his name can literally mean "expert stage".
    • The name Kuroto is a corruption of Puroto, the Japanese pronunciation for "proto-", referring to the Proto Gashat he initially uses.
  • Momma's Boy: And how! Even Poppy lampshades it a few times.
  • Morality Pet: His mother seems to be the only person on the planet he genuinely loved that's not himself. Due to her having been Poppy's host, this carries on to her to some degree.
  • The Most Dangerous Video Game: His end goal for Kamen Rider Chronicle. He wants to create a game where everyone becomes a Kamen Rider and is put into an endless fight for survival.
  • My Death Is Only The Beginning: He needed "death" data to complete Dangerous Zombie. It didn't necessarily have to come from someone else.
  • My God, What Have I Done?: Subverted. He winds up regretting the creation of Kamen Rider Chronicle and wanting it off of the shelves, not because of the immorality of the system, but because his father has steered it away from his intended scenario.
  • Narcissist: Has all the symptoms of a malignant narcissist. He has a complete Lack of Empathy for anyone that's not him, to the point even getting his own father thrown in jail as part of a hostile take over, but is quite capable of pretending he does; has an extremely over inflated opinion of himself to the point of A God Am I; and views the Riders as all being disposable 'play testers' for his schemes he's entitled to manipulate however he pleases. Most tellingly, however, is he's prone to particularly violent narcissistic rages whenever something is introduced to 'his game' that he himself is not responsible for making, such as the Mighty Brothers XX Gashat and Burgermon, both of which are from games he didn't personally create. He's also not only willing to murder people for minute slights, he's shown to take a level of sadistic joy from it.
    Kuroto: As if! What's terrifying is my own talent!
  • Necromancer: A very mild example, but he brought back Poppy by cultivating what's left of her virus in his body. Yeah…
  • Nice Job Fixing It, Villain!:
    • Having managed to steal every Gashat but the ones in Emu's possession, Kuroto gets greedy by creating the Gashat Gear Dual Beta, which when stolen from him allows Hiiro and Taiga to regain the ability to fight and to start taking back the other lost Gashats.
    • Also, getting Emu involved eventually led to the creation of Maximum Mighty X, which was followed by his downfall and death at the hands of Parado.
    • Repeatedly killing Emu in his Game World in the Gorider miniseries (including revealing his identity in a moment of cockiness because he knows Emu won't remember it) allows Emu to leave messages to himself he uses to ultimately piece together what's happening.
    • Choosing Kenzaki as his disguise in the above special ultimately ended up drawing the real Kenzaki into the game world, as being a Joker Undead, Kenzaki could sense his artificial Undead based powers. As Kenzaki is a Joker Undead, him entering the game world automatically made him the only Undead present and thus the technical winner of the Battle Fight… which Kenzaki points out results in The End of the World as We Know It. In this case, Kuroto's game world, resulting in his resurrection plan going up in flames.
    • Remember that Emu had an operation as a kid (one headed by Kyotaro) that inspired him to become a doctor and gained interest in video games due to an accident. The cause of that accident? It was due to the game disease from the Mighty Action C demo that Kuroto gave to him taking its effect, making him feel sick while crossing the street on a rainy day and thus a car ran over him.
  • Omniscient Morality License: A villainous example. Kuroto justifies all of the murders and near fatal injuries of civilians because anyone who dies will be saved as data and can be restored.
  • One-Hit-Point Wonder: After his revival, Kuroto's extra lives essentially function as his hit points, as he becomes incredibly fragile. At one point he outright dies of stress, twelve times in a row, in one night.
  • Out-Gambitted: Kuroto never could have finished Kamen Rider Chronicle even if he'd wanted to: Parado had the last two Bugsters with him the whole time.
  • Out of Continues: Emu uses Maximum Gamer to strip him of his immortality, meaning next time he dies will stick. Kuroto does not take that well, and Parado soon takes care of his "last life". But of course, he had ninety-nine extra continues just in case.
    • By True Ending, he's down to just one life left.
  • Pet the Dog:
    • Throwing himself in front of Poppy to protect her from an attack by Parado, at the cost of his second continue, serves as a major sign that Kuroto is not beyond redemption.
    • After Kiriya spends the better part of the episode infecting Kuroto with the Gamedeus virus and repeatedly killing him until he's down to four lives, Kuroto repays the favor by using his newly developed Gamedeus antibodies to heal Kiriya of the same virus, even though he could've easily gotten revenge by leaving Kiriya for dead and just finished programming the ultimate antibody into the Doctor Mighty XX gashat on his own.
  • Power Degeneration: Parado reveals that Kuroto's usage of the Proto Mighty Action X Gashat makes him incredibly powerful, but is damaging his body with every use. He later circumvents the issue by getting himself killed and reviving using Dangerous Zombie, at which point he stops using Mighty Action X in favor of his shiny new Level 10 form.
  • Professor Guinea Pig: Infected himself with Game Disease to give him the ability to transform using the Game Driver.
  • Psychopathic Manchild: He's gradually revealed to be one of these, but it becomes more evident once he winds up under Poppy's maternal thumb from #30 onwards. It's Played for Laughs in later episodes.
  • Rasputinian Death: In the Gorider special, he takes the brunt of the Gorider Tower attack, then hit dead center by the Gorider Bazooka with Ex-Aid Level 99's power added into it. All this only succeeded in destroying his powered up armor and badly wounding him, at which point the four dead Riders finally kill him for good by grabbing him and pushing him into his own black hole-like warp he was attempting to use in a Taking You with Me while the world was fading into nothing, which would've finished him if that didn't.
  • Redemption Demotion: After joining our heroes at CR, he's become less menacing and strong in battle. Although his Crazy-Prepared intellect shouldn't be taken lightly. Just ask Masamune.
  • Reasonable Authority Figure: Takes care to cultivate the image of one during the first ten episodes, acting as a caring friend to the Riders right up until the moment they discover his identity.
  • Restraining Bolt: After his revival as a Bugster, Poppy can imprison him in her Buggle Driver II if he does something dangerous.
  • Rival Final Boss: Played With. While he does become the final boss post-series, the person who faces him isn't Emu, but rather Kiriya, though throughout the show, he has had a rivalry with him. Though in the epilogue novel, Emu does face Kuroto one last time.
  • Sadist: He just loves giving people a bad day.
  • Sanity Slippage: After his reveal as the Big Bad, Kuroto becomes increasingly hammy, manic, and prone to fits of rage with each passing episode. By episode 23, he completely loses it, doing everything he can to try and hurt whatever is in his way, and eventually being reduced to a screaming mess who can barely think straight, if at all. He regains at least some of his sanity by the time of his resurrection as a Bugster, but remains a gigantic ham.
  • Science Hero: As the creator of the Game Drivers and Gashats, he becomes one of these (though the "hero" part is very questionable) after he decided to join forces with the Doctor Riders stop Kamen Rider Chronicle.
  • Shoe Phone: Plugged into a regular GENM Corp console, his Gashats function like typical video games (and they look exactly like the regular cartridges he sells on the market) with their transformative properties only activating when slotted into a Game Driver.
  • Sincerest Form of Flattery: Averted. He views the Mighty Brothers XX Gashat as an illegal bootleg, and plots to steal it and delete its data. This is also the reason why he kills Burgermon. On a larger scale, Emu sending him a fan letter with game ideas of his own was Kuroto's Start of Darkness.
  • Sixth Ranger: By #31, he's become the sixth active Rider on the CR team.
  • Slasher Smile: Capable of quite the manic grin, with episodes 5 and 11 having the early standouts. By the late teens he makes several in nearly every episode. They become a bit more rare after his resurrection, but he's still capable of delivering them now and again, such as when showing off his new Gashat to the Riders.
  • The Social Darwinist: He intends to enforce the entire world to fight to survive in his ultimate game. Taken Up to Eleven, when he creates Kamen Rider Chronicle.
    Genm: (After having lifted Emu up to choke him) Only the strong survive.
  • Soft-Spoken Sadist: Always maintains a polite tone, even when taunting his opponents. At least until he loses his shit and starts yelling at his enemies when he realizes his position is compromised.
  • Soul Jar: The true purpose of the Proto Gashats outside of play-testing.
  • Suicide by Cop: One interpretation of his actions in episode 11, albeit not for the usual reasons.
  • Suicidal Overconfidence: His treatment of Parado, considering that Genm's highest level is 10 while Parado is Level 50. Episode 18 sees him get hit with some well deserved Mistreatment-Induced Betrayal in the form of Extreme Mêlée Revenge.
    • Later on he takes on a Level 99 foe at Level 0, which counts right up until Kuroto reveals Level 0's Level Drain skill.
  • Taking You with Me: When defeated in the Gorider special, he attempted to take Emu and Kenzaki down with him using a blackhole like attack. The four dead Riders instead grab him and push him into it, resulting in him only killing himself… again.
  • Tall, Dark, and Handsome: 186cm tall and played by a fashion model.
  • Teens Are Monsters: He was around the age of fourteen when he got Emu infected with the Bugster Virus.
  • Teen Genius: At the age of fourteen Kuroto was already a successful game developer with many well-regarded titles under his belt.
  • Tritagonist: While his actions drove the majority of the first half of the plot, he is quickly overshadowed by the other major villains of the story (Parado and Masamune) and even spends a sizeable stretch of episodes without making an appearance in-series. After his resurrection, the story's focus switches to building on Emu and Parado's relationship, and Kuroto is mostly relegated to the role of Comic Relief. That said, Genm does start off as Ex-Aid's Evil Counterpart, and when he and Emu both first fight as team, Poppy refers to them as "The Two Mighties".
  • Thanatos Gambit: Many times over. His first death allowed him to craft Dangerous Zombie, while his repeated deaths in battle served to awaken its full potential.
  • They Call Me Mister Tibbs: After his resurrection as a Bugster he begins to refer to himself as Shin Kuroto Dan, and insists others do as well.
  • Token Evil Teammate: After being brought back from the dead by Poppy, Kuroto has joined up with the CR Riders to complete Kamen Rider Chronicle, albeit not without getting some payback against Parado.
  • Took a Level in Badass: After being resurrected as a Bugster and taking back his Dangerous Zombie Gashat from Parado, Kuroto can transform into Genm Level X-0 without the need of a Buggle Driver.
  • The Chessmaster: Best demonstrated in his manipulation of Graphite into stealing a Proto Gashat, making him enough of a threat that the Riders would have to team up and use Drago Knight Hunter Z together to beat him.
  • Unknown Rival: To Emu back when they were children, to the point that he has to spell it out that he's been trying to destroy his life for more than a decade.
  • Unwinnable by Design: He made Kamen Rider Chronicle nearly impossible to finish so that it would stand as an eternal testament to his genius.
  • Villainous Breakdown: Episode 23 sees him go through a rather extensive one, even by his standards.
  • Villain Takes an Interest: Claims to Kiriya in episode 8 that he's curious about how Emu is able to use a Gamer Driver considering what's required first. Of course, he already knows, since he was involved.
  • Villainous Rescue: While he bails out Emu at Poppy's request in #30, it's mainly because of his personal beef with Parado.
  • Villain with Good Publicity: Manages it for the first ten episodes, except with Kiriya who doesn't matter. Eventually, his identity as Genm comes out and he's on the run from the authorities, even dubbed as "bio-terrorist".
  • Virtual Ghost: His spirit returns in the Gorider miniseries, inhabiting a game world he created as a contingency plan so he could resurrect himself if he died. He ends up getting killed again, presumably for good this time, until it turns out he had a second virtual ghost in the Proto Mighty Action X Origin Gashat which allowed him to come back to life as a Bugster.
  • Walking Spoiler: Because of his central role to the story and frequent shifts in allegiances, along with his repeated deaths and resurrections, it's virtually impossible to talk about Kuroto's actions in any significant capacity without spoiling major swathes of the story.
  • What Is One Ride-Player's Life In Comparison: When Nico is infected with Gamedeus's Game Disease, Kuroto is more concerned with defeating Cronus, attempting in his own way, to comfort Nico into accepting her own death so they can focus on that, saying she could always come back as a Bugster like he and Kiriya. Nobody, least of all Kiriya, is amused.
  • Would Hurt a Child: He'd murder a child to get the data on Death he needs.
  • You Have Outlived Your Usefulness: Says outright in episode 18 that "Those who have served their purpose are disposed of." This applies equally to Riders and Bugsters.
    • Ironically, it also applies to him. By #23, Parado doesn't need him anymore as Kamen Rider Chronicle is nearly completed.

Tropes exclusive to him as Kamen Rider Genm

Saijoukyuu no Kami no Sainou!note  Kuroto Dan! Kuroto Dan! God Maximum X!
  • Ace Custom: If the Proto Game Quest Gamer and Proto Shooting Gamer are of any indication, then Genm ought to be grey and not black. Proto Mighty Action X Origin goes one step further by having several powers and much higher stats that Ex-Aid's regular Level 2 Action Gamer doesn't have.
  • All Your Powers Combined: After getting a hold of their respective Gashats, Genm modifies Dangerous Zombie to allow himself access to the Gashacon Sparrow, Sword, and Magnum to use in combat. Unlike the other Riders, he can summon and use them simultaneously. He later does it to himself by using Dangerous Zombie and Proto Mighty Action X Origin at the same time, letting him combine the latter's useful debug tools with the significantly better combat performance of the former.
    • Using the Kamen Rider Battle: Ganbarizing Gashat, he can summon forth duplicates of past heroes and use it with his own belt to unleash a devastating finishing move that has the power of over a dozen Kamen Riders.
  • An Adventurer Is You: Level 0 is a Status Effect Guy, Debuffer type. By making contact with enemies he can nullify their power, which amounts to a temporary Level Drain. It's especially useful against Parado since he can reduce him from Level 99 to Level 50 within a matter of seconds.
  • Anime Hair: Being a Palette Swap of Ex-Aid, he also shares this aesthetic with him. He continues to have the same "hair" in Zombie Gamer form, since, going by the game label, Dangerous Zombie's hero has similar hair to Mighty.
  • Bad Powers, Bad People: The guy with undead, zombie themed powers is a bad guy. Who would've guessed?
  • Brilliant, but Lazy: Kuroto shows on many occasions that he's fully capable of being a skillful and highly effective fighter when he wishes to be, but after his revival, his multiple lives and resulting Suicidal Overconfidence lead him to often forgo any patience or technique in battle in favor of a style that could charitably be described as drunken flailing. Dangerous Zombie's influence seems to be a factor in this regard, as he typically regains his technique when using Proto Mighty Action X Origin on its own.
  • Brought Down to Normal: Thanks to the Maximum Mighty X Gashat, he first loses his immortality as the Zombie Gamer, and then loses the ability to transform when Maximum Gamer removes his compatibility.
    • Brought Down to Badass: After his revival he's still lost his immortality, but makes up for it with a close approximation and the new powers of his Level 0 form.
  • Can't Catch Up: Ping-pongs back and forth between playing the trope straight and averting it. Being the only Rider to start with a Level 3 form and having the most experience as a fighter, he greatly surpasses all of the other Riders at the start, but his advantages swiftly begin to disappear as the Level 3 Gashats enter circulation. He receives a boost when he gets his Level 10 form, which brings him back to being nigh-invulnerable, but it too proves to have its limits when faced with a Level 50, so he upgrades it to Level X. Eventually that too is outmatched, and finally he settles for being Level 0, but with the ability to drag everyone else down to his level.
    • Hilariously, Kamen Rider Cronus (his own invention) makes almost all of his new abilities gained from Proto Mighty Action X Origin nigh-useless. He's an enemy that doesn't have any levels to reduce, he's a Kamen Rider with no Bugster powers to suppress, and he can "lock" his enemies in a perpetual state of death which could "kill" Kuroto indefinitely no matter how many lives he has left. Which he later counters with God Maximum X, who's level is so high, the level free riders are eclipsed.
  • Clipped-Wing Angel: Dangerous Zombie becomes this after Kuroto wins it back from Parado as it is still under the effect of Emu's reprogramming, depriving him of the Gashat's advanced functions such as Resurrective Immortality and self-replication. It does become stronger due to being paired with Proto Mighty Action X Origin, though, so it's not a complete loss.
  • Colony Drop: A moon to the face was undoubtably going to be a bit too much for Cronus to handle.
  • Cool Bike: And unusually for Kamen Rider, it's a BMX Bike. He can still kick ass with it, though. To the point that he almost killed all the other Riders with it, mind you.
  • Cool Sword: Proto Mighty Action X Origin gives him a Gashacon Breaker identical to Ex-Aid's, which he also uses when combining it with Dangerous Zombie. He seems to prefer it in sword mode.
  • Curb-Stomp Battle: Practically the only thing he does for the first few episodes is show up to deliver these and leave. He later ends up on the receiving end of a few, but continues to dole them out on occasion. Just ask Kiriya and Burgmon.
  • Collective Identity: Briefly used as a distraction in episode 7, though Parado never actually wore the suit.
  • Darker and Edgier: Dangerous Zombie is the first Gashat introduced that doesn't come with a cute support robot "gamer" to add its load out atop the Rider that summoned it.
  • Deadly Upgrade: Inverted: his original powers were killing him, while Dangerous Zombie not only prevented his death but seems to have undone any health issues caused by Proto Mighty Action X.
  • Death Is Cheap: Through Dangerous Zombie and Proto Mighty Action X Origin. The former gave him infinite resurrections, the latter grants 99 extra lives.
  • Debug Room: Proto Mighty Action X Origin, the basis for Genm's Action Gamer Level 0 and Zombie Action Gamer Level X-0 forms. In addition to granting all the same abilities as Proto Mighty Action X, it grants a host of useful debug features such as the ability to nullify certain Bugster powers or make Dangerous Zombie compatible with the Gamer Driver.
  • Drop the Hammer: Proto Mighty Action X Origin gives him a Gashacon Breaker identical to Ex-Aid's, which he also uses when combining it with Dangerous Zombie.
  • Dynamic Entry: He can control the trajectory of his respawns, allowing for offensive and defensive ambush attacks.
  • Expy: Within the franchise, his form progression is akin to Chase, going from a black prototype of the main Rider's suit to a corrupted version of the same. In general, he's one to every evil Palette Swap in gaming.
  • Finishing Move:
    • Mighty Critical Strike
    • Mighty Critical Finish
    • Shakariki Critical Strike: Charging power into the wheels, Genm jumps the Shakariki bike into the air and spins like a helicopter, hitting everything around him. In Level 3 form, Genm removes the right wheel from his armor and after charging it, hurls it at his target(s).
    • Episode 8 showcases a variant using both the right wheel as well as the Bugvisor's chainsaw to perform a double slash.
    • Critical End: A Rider Kick exclusive to Zombie Gamer form, Genm first press the A button of the Buggle Driver twice. Charging energy in the form of black mists into his body, he then leap into the air and perform multiple spinning kick against his target.
    • Critical Dead: Genm creates multiple shadow zombies which closes in on the enemy. After they get close enough, they all explode simultaneously, causing a massive explosion. Upon achieving Level X, he can use it to make copies of himself instead, and rather than explode they can corrode a Rider's Gamer Driver into uselessness while leaving them alive and helpless.
    • God Maximum Critical Blessing: A powerful Rider Kick executed by closing and reopening the lever on his Gamer Driver while using God Maximum Mighty X.
  • Find the Cure!: Genm and Lazer are the best hope for a cure to the Gamedeus virus as bugsters are capable of developing an immunity over time. The problem is that people are dying now and Lazer doesn't think there is time to infect one of them and let the immunity develop naturally. The answer, force Genm to burn through his lives in order to accelerate the development of his immunity. Kuroto's god complex means once he realizes the plan, he's sort of willing to go along with it, because someone tampered with his creation and he sees himself as ultimately unkillable. Once he develops an immunity, he's so elated he lets Lazer kill him one more time just for the hell of it.
  • First-Episode Spoiler: His identity is revealed almost immediately to the audience.
  • Flawed Prototype: Uses the Proto Mighty Action X Gashat. While it's supposedly limitless in its potential, it has a critical design problem: long term use will ruin its user's body. Though this seems to no longer be an issue once Kuroto comes back as a Bugster.
  • Foil: To Ex-Aid. Aside from the obvious, while Emu is excitable as Ex-Aid and is talking up a chatter while being as flashy as he can, Genm is always calm and quiet, only using more powerful attacks when he needs to and relying on an effective yet less flashy fighting style. Also, while Emu is constantly disrespected and looked down on but is secretly highly competent and confident as M, Kuroto is seen as a kind individual and has great respect from members of the hospital, but is secretly an arrogant and corrupt individual as Genm.
    • Amusingly, they end up in a complete reverse situation as the show goes on; Ex-Aid becomes a more serious fighter due to the show's events, while Kuroto embraces his inner Large Ham to the fullest after completing Dangerous Zombie and replaces his methodically effective fighting style with inhuman, unhinged movements.
  • Glass Cannon: This seems to be fundamental to the nature of Dangerous Zombie which has high offense but intentionally terrible defense and durability. At Level 10, it's at least twice as strong as the other riders at the time of its debut yet is frequently pushed back or injured by lower level forms. With built-in resurrecting immortality, it simply doesn't matter if he can be killed as he'll be back on his feet almost instantly, and making his health low guarantees that a few hits from them will kill him. Combined with the massive power boost of Level X, and the fact that said power boosts come from harnessing each death inflicted on him, Genm is intended to be unstoppable. This poor defense causes an issue following the loss of his immortality. Level X-0 is very powerful and this combined with his various cheat abilities means he should be able to fight or perhaps even defeat any rider bar Cronos or Hyper Muteki Ex-Aid. But his lack of defense means he's the easiest rider to drop and without his immortality, he'll sacrifice a lot of lives in a fight. Exemplified in his fight with Lazer Turbo to develop the perfect Gamedeus antibody, where he's at least as offensively powerful but his poor defense means that he drops from 82 lives to just 4 by the end of the fight, whereas Lazer doesn't come close to death until the end of the battle.
  • God Game:God Maximum Mighty X invokes this genre of game, and as such makes Kuroto a Reality Warper. He's naturally a Cruel Player-Character God.
  • Goomba Stomp: Delivered to Lazer at the start of every closing eyecatch. Cue the "Funny Aneurysm" Moment.
  • GMPC:
    • Genm's Zombie Gamer form is basically this, being custom-made to give Kuroto, who sees himself as the Game Master of the entire thing, a gigantic and unfair advantage in the 'game' with abilities that no one else has. Most notable is his Resurrective Immortality, but he can also block the Gamer Driver's safety feature that protects the user by ejecting the Gashat when they're running the risk of a Game Over.
    • Then comes his Level 0 with his anti-Bugster skill and ninety-nine lives. Stat-wise, for such a lowly level he's on par with a Level 10. However, combining the skills of Proto Mighty Action X Origin with Dangerous Zombie's Level X stats and necromancy in the Gamer Driver turns Genm into a super dangerous Game Master.
  • Golden Super Mode:
    • In the Gorider miniseries, he gets a far stronger final form with golden armor by using the power of despair he'd absorbed. It's powerful enough to overpower Ex-Aid Level 99.
    • Parodied with the Hyper Muteki Gashat, which made him invincible and exponentially more powerful for ten seconds when he used it. He then proceeded to squander the time limit by explaining how his invention worked and laughing about how unbeatable he temporarily was.
  • Good Powers, Bad People: Near the end of the series, he manages to develop an immunity against Gamedeus' strain of Game Disease and uses it to create a Gashat to best him. This doesn't make him any less of a villain and Kiriya doesn't hesitate to lock him in a Bugvisor so he can hand his imprisoned self to the government once Doctor Mighty XX is finished.
  • Hero Killer: Episode 12 has him use his Level X form to kill Lazer and he takes the GiriGiri Chambara Gashat. Episode 22 follows it up with an encounter with Emu where he melts Emu's Gamer Driver.
  • Heroes Prefer Swords: Subverted. Without access to a Bugvisor of his own, he starts using the Gashacon Breaker after he's forced to ally with the Doctor Riders, but he's a comically socipathic Anti-Hero for the most part.
  • Irony: His main Level 0 ability was to debuff the levels of other Riders and get them down to something negligible enough for him to deal with. Lazer Level X manages to take out the abilities of God Maximum Mighty X by using reset to debuff him down to a point where both can only beat each other to the death with their fists.
  • Knight of Cerebus: The only Rider whose scenes are never played for comedy and never fights using a Level 1 form. The show starts to become Darker and Edgier as soon as his Level 10 form makes its debut, with him killing off Kiriya. This gets averted later in the show as Kuroto becomes a much sillier comic relief character, with his fights as Genm often reflecting this.
  • Lethal Joke Character: Genm's Level 0 form is not as strong as his Level X form, but its powerset is very, very useful for dealing stronger Bugsters as beholden by Perfect Knock Out Para-DX. When he retrieves Dangerous Zombie and combines the two together, however, he becomes even stronger than he was before, though still not quite up to Level 99 levels of might.
  • Let X Be the Unknown: Invoked. Kuroto explains in episode 20 that labeling Dangerous Zombie as "Level X" instead of "10" isn't just a fancy flourish, but represents a distinct concept from the Gashat's base level of 10. Where Mighty Brothers XX, also a Level X Gashat, had the ability to split the user into two identical Level 10 forms whose power would sum to Level 20, Dangerous Zombie gathers more data on death every time the user is slain in battle and revives, until it reaches a certain threshold and erupts in an enormous boost to the user's power. In this fully awakened state, Kuroto claims that Genm's power becomes immeasurable by the concept of levels, though in practice it's akin to achieving Level 75 or so, plenty enough to handle anything up to that point with ease. For Dangerous Zombie, "X" represents both the Roman numeral for ten and the algebraic variable.
  • Level Drain: As Genm Level 0, he can drain the levels of the enemy he touches temporarily.
  • Lighter and Softer: Genm in Level 0 and X-0 Forms would usually respawn from a purple Warp Pipe, fitting with his newly-formed Heroic Comedic Sociopath attitude.
  • Mecha Game: God Maximum Mighty X, appearing in the Genm vs. Lazer V-Cinema. It's a Palette Swap of Maximum Mighty X with all of the same abilities, but it's at Level Billion.
  • Me's a Crowd: Upon achieving Level X, Kuroto can send phantom copies of Genm to other places to fight in his stead, even if he's not currently transformed, or make dozens of copies at once using Critical Dead. As he lampshades, zombies tend to come in hordes.
  • Mismatched Eyes: Zombie Gamer's eyes are actually of the same color, but the suit features a cracked red visor that gives the impression that it has one red eye. It makes a good match to his black and white hair.
  • Mook Maker: The Dangerous Zombie Gashat allows him to create a small army of zombie inspired Bugsters.
  • My Hero Zero: Using Proto Mighty Action X Origin puts his Genm form at Level 0. The number is nonindicative of its strength, as it's essentially a debug tool, with features no other Gashat has like the ability to continue and Level Drain Bugsters.
  • Nerf: Played with. After his revival he's left with limited lives, making him less dangerous, but he does also get new and useful powers.
  • Nigh-Invulnerability: During the Another Ending trilogy, Kuroto opts to develop his own usable version of the Maximum Mighty X gashat, but instead of creating another Hyper Muteki power-up to go with it, he develops its base component further to GOD Maximum Mighty X. Since it lacks the invincibility of Hyper Muteki, Kuroto can still be damaged while using it. In exchange, its Level is 1,000,000,000 so conventional attacks barely matter to him anyway and he's amped up the Reality Warper programming powers of the gashat to ludicrous extremes.
  • Not So Stoic: While Kuroto still needed to maintain his secret identity, he acted rather reservedly as Genm, barely speaking while coming and going in a rather subdued fashion. After the deception is lifted, he becomes wilder and chattier during fights.
  • Number of the Beast: Supplementary information about Genm's statistics once he ascends to Level X include details like his punching power striking with force equivalent to 66.6 tons, while his maximum jumping height as Zombie Action Gamer Level X-0 is 66.6 meters.
  • Ominous Visual Glitch: His Level X form is accompanied by plenty of these, fitting its status as a Survival Horror themed form. Turns out it's not just an artistic idea: according to All There in the Manual materials, his helmet emits a special light that causes optics to malfunction and enemies to see hallucinations, invoking this trope in-universe.
  • Only Known by Their Nickname: For the first ten episodes, Genm never declares his Rider name, or much of anything else, prompting them to simply call him 'the black Ex-Aid.' Justified, as Kuroto has an obvious interest in not stating his Rider name in their presence, given it's the same as the name of his company and would be a clue to his identity. As soon as keeping up the charade is no longer needed, he ditches this trope entirely and reveals not only his proper name but who he actually is to the other Riders.
  • Our Zombies Are Different: In two ways: Genm survived the creation of Dangerous Zombie with unclear effects on his physical and mental health, for the most part appearing to still be alive and human. Dangerous Zombie itself is styled after a cybernetically-enhanced zombie, such as the ones from Doom. Fittingly, Emu renders him mortal by essentially bringing him back to life.
  • Palette Swap: Acknowledged as such in-universe, with his Level 1 and Level 2 forms being simple recolors of Ex-Aid's own. His actual Rider name isn't even known for the first ten episodes, instead simply being referred to as "the black Ex-Aid". Although, given that Genm was technically created first, Ex-Aid could be considered a "pink Genm." His Level 10 form becomes more distinct, retaining only Ex-Aid's hairstyle. He later becomes a Palette Swap to himself with Level 0, which is identical to Level 2 except that the lines are silver instead of purple.
  • Platform Game: Proto Mighty Action X, the basis for Genm's primary Action Gamer Level 1 & 2 forms. It bestows great mobility, allowing amazing jumps in a Mario-esque fashion. It also gives him the ability to summon digital platforms in midair that resemble blocks of chocolate.
  • Power Nullifier:
    • Dangerous Zombie can nullify the forced ejection feature of a Gashat if he wants it to, requiring users to manually eject or die.
    • Proto Mighty Action X Origin suppresses nearby Bugster infection in general, preventing nearby Bugsters from taking over their hosts. It can also nullify Bugster powers in the game world.
  • The Psycho Rangers: During his DVD mini-series, he creates a squad of minions that unintentionally mirrors the now defunct five Rider team-up from the movie that preceded it consisting of data copies of Kamen Rider Double, Kamen Rider OOO, Kamen Rider Fourze, Kamen Rider Hibiki, and himself.
  • Purple Is Powerful: Genm has purple details on his Level 2 suit. While they're abandoned with Dangerous Zombie, the new Buggle Driver he uses is purple.
  • Reality Warper: God Maximum Mighty X essentially turns Kuroto into the god he always viewed himself as, and as a result, he’s nearly unstoppable. Among these powers are the ability to create a sunbeam so focused that it turns into a laser, summon meteors from above to rain down on his opponents, or even hitting his enemies with the goddamn moon after punching them into space.
  • Red Eyes, Take Warning: Unlike Ex-Aid, who has orange eyes, Genm has red eyes with black rings in them. Also Genm's eyes are "angrier" with a slanted curve, unlike Ex-Aid's more "confident" eyes. When using Dangerous Zombie Genm's eyes become blue, but one of them is covered by a cracked red visor.
  • Resurrective Immortality: His primary advantage once he acquires Dangerous Zombie. It's actually a Healing Factor, and does have limits, but they're immensely difficult to reach. Emu strips him of it, allowing him to be defeated by the Riders and then killed by Parado, but he later gets a new kind with limited uses. Not that 99 lives is a particularly worrisome limit.
  • Revive Kills Zombie: It's not quite as easy as throwing Recovery energy items at him; When Emu uses Maximum Gamer, which was made with Kiriya's research on reprogramming the Bugster Virus within an enemy, to strip him of his immortality, it results in his life gauge going from the dead, empty state it was in due to him being undead to full. He'd been unkillable because You Can't Kill What's Already Dead, but Emu essentially rendered him mortal by bringing him back to life.
  • Rings of Death: In his Level 3 form, Genm can utilize his bike's wheels in this fashion.
  • Sinister Scythe: After he kills Kiriya, he claims his Gashacon Sparrow as his own. Fitting for his death motif, he prefers it in this mode.
  • Sports Game: Shakariki Sports, the basis for Genm's Sports Action Gamer Level 3 form. It equips him with a set of shoulder-mounted Deadly Discs and improves his all-around performance.
  • Squishy Wizard: While Genm Level X-0 comes with 99 extra lives and a host of useful features, Kuroto desperately needs those extra lives, as he has almost no defensive ability and dies when hit by anything more dangerous than a stiff breeze.
  • Stone Wall: As an antagonist, while his ability to revive himself using Dangerous Zombie does have an upper limit, it's absolutely enormous: where Ex-Aid in a Level 10 form was defeated in a single shot from a Level 50 suit that wasn't even being worn, Genm endures a Rapid-Fire Fisticuffs assault from another Level 50, gets hit so hard at the end he gets sent flying into a mountain that explodes, and then still needs to take a a triple Super Strength boosted Rider Kick to finally get his Gashat to eject. On the other hand, his offensive abilities aren't anything to write home about, rarely able to do damage of any note to other Riders at or above his level. Once he switches sides, he becomes a Squishy Wizard.
  • Strong as They Need to Be: According to supplementary information, Genm's statistics and ability parameters such as jumping height, speed, and punching power while in God Maximum Gamer Level 1000000000 are "freely configurable", which is about as much this trope as you could get.
  • Super Prototype: The Proto Mighty Action X Origin Gashat has better stats than the Proto Mighty Action X Gashat with the additional bonus of having Level Drain, ninety-nine lives, and a Gashacon Breaker.
  • Survival Horror: Dangerous Zombie, the basis for Genm's Zombie Gamer Level X and Zombie Action Gamer Level X-0 forms. It initially requires the Buggle Driver to use rather than the Gamer Driver, and grants a host of powers such as immortality and self-replication.
  • Swiss Army Weapon: Genm's Gashacon Bugvisor, a wrist-mounted multi-tool that doesn't conform to the other Gashacon weaponry. To swap modes, all that needs to be adjusted is how it's held. Also, it has THREE modes, compared to the others' two. Given its owner, it isn't surprising to see why it's overpowered.
    • Beam Gun Mode: Shoots out twin laser blasts.
    • Chainsaw Mode: Cuts through everything in its path.
    • Pad Mode: Allows the weapon to rest on a belt buckle. When combined with the Bugster Buckle, it is known as the Buggle Driver.
    • There's apparently one more mode that allows Bugster generals to change into their true form. And it has a glitchy and twisted version of the Riders' transformation call.
  • Technically Living Zombie: Genm's Level X-0 form qualifies as this, since it looks similar to his Level X form with the Buggle Driver replaced by the Gamer Driver.
  • Technician vs. Performer: The technician to Ex-Aid's performer. While his fighting style uses simple, yet effective brutal attacks to overpower his opponents and keep them down, Ex-Aid's is flashy, focuses on agility, and makes use of energy items to win.
  • Unskilled, but Strong: His main advantage, and his main weakness. He dominates fights only when he has a clear and decisive edge in terms of sheer power over the other Riders, who actually play video games or otherwise have combat-useful skills. When they gain an equal level to him, he's quickly defeated.
  • Video Game Genres: Though he's not one of the Medical Riders, Genm can still utilize all the benefits of Rider Gashats that they can... and perhaps he can do even more.
  • The Voiceless: Maintained for the first five episodes, with the next five having him speak using a heavily modulated voice when he's not around people who know his identity. Once it comes out, he drops any pretense and speaks normally.
  • Voice of the Legion: From episodes 5 to 10, the only times in which he speaks while his identity is concealed. He also has a more subdued version during his first use of Dangerous Zombie, but drops it afterwards.
  • Weaponized Car: Inverted with his bike variant. The Shakariki Sports bike that Kamen Rider Genm summons becomes his armor of all things when he upgrades into Sports Action Gamer. He even uses the wheels like Deadly Discs! The trope can also be played straight if he puts Shakariki Sports in the finisher slot instead, like he does in his pre-show cameo appearances.
  • You Can't Kill What's Already Dead: As Zombie Gamer Level X is programmed with death data, he can't really be defeated even though his HP is 0. However, a higher-leveled gamer may overwhelm him to the point he can be forced out of transformation. His second death comes from reversing this, making him alive again so he must fear death. The Riders only intended to force him to behave by taking away his advantage, but Parado is more than happy to finish him.

    Masamune Dan/Kamen Rider Cronus 

Masamune Dan/Kamen Rider Cronus

https://static.tvtropes.org/pmwiki/pub/images/masadan.png

Played by: Hiroyuki Takami

"Now, it's time for Judgement!"
Former CEO of Genm Corporation and father of Kuroto. Was imprisoned, but recently released and is now back as the CEO of Genm Corp. In reality, he's actually Evil All Along, using Kuroto as his Unwitting Pawn to complete Kamen Rider Chronicle. After revealing his true colors, he transforms into Kamen Rider Cronus through the Buggle Driver II and the Master version of the Kamen Rider Chronicle Gashat.

In episode 42, fed up after the Riders spoiling all of his plans, he kills Gamedeus and absorbing its data, becoming the True Final Boss of Kamen Rider Chronicle. Was brought back along with his Bugster in Kamen Rider Genm vs. Lazer only to be killed off by Kuroto.


  • A God Am I: "I am the rule of this world."
  • Abusive Parents: To the point where he viewed his own son's talents as merely a product of the Genm Corporation. Given how many of Genm's shown games were Kuroto's ideas it goes to show how little he values his son, and why Kuroto ended up the way he did.
  • Ace Custom: He creates a personal Genm game console that allows him to delete and reinstall Bugsters with his Kamen Rider Chronicle Gashat from the comfort of his office.
  • Archnemesis Dad: Turns out to be even worse than his son and is now the series biggest threat.
  • "Awesome McCool" Name: Masamune Dan.
  • The Battle Didn't Count: In episode 40, Emu and Parad prove to be too much for him and destroy the Kamen Rider Chronicle Master Gashat. Unwilling to stop, Masamune uses his own Bugster infection to rewrite reality, undoing his loss and erasing Hyper Muteki from existence.
  • Beneath the Mask: At first appears to be a good person who was The Scapegoat for Zero Day, and is a Benevolent Boss to his employees. Beneath that is a Sociopathic monster who views everyone but himself as a product to use or dispose of as he sees fit. And seemingly beneath that is a man who loves his wife dearly and disapprove of his son for soiling her memories.
  • Better to Die than Be Killed: How he and his regimen ended: He injected the Kamen Rider Chronicle Master Gashat into his body, dissolving him into data, technically giving himself a Game Over to assure that other game over victims would not be saved. Unfortunately he ended up getting brought back to be killed off by his son in the sequel trilogy shorts.
  • Big Bad: The true mastermind behind Kamen Rider Chronicle. Once he becomes Kamen Rider Cronus the plot shifts to everyone trying to stop him from trapping everyone within the game.
  • Brought Down to Normal: In the last episode, Parado's Heroic Sacrifice from the previous episode interferes with Masamune's virus, causing his powers to start breaking down. It starts with Emu being able to move in his time stop, which then stops working outright, and ends with him being weakened to the point where he can be beaten by the Riders at Level 2.
  • Came Back Wrong: Implied: after merging with Gamedeus, he gets a Game Over...but doesn't vanish. He then declares That Man Is Dead in a tone completely different than his mannerisms immediately prior, implying that while Masamune's body is still alive, he's no longer the one inside it. It's just him being a ham like his son, though.
  • Catchphrase: “ZEPPAN DA.”, often used when insulting something.
  • Combat Pragmatist: Other than his power edge, this is his main form of making up for his poor combat ability. Masamune basically does everything in his power to make a fight against him as unfair as possible for his opponents.
  • Control Freak: Makes a big deal of stating how he controls everyone's fates and seems to take pleasure in doing so. In fact, his intended goal for "Kamen Rider Chronicle" is basically to get as many human lives under his control as possible. Notably the only thing that seems to anger him is that control slipping.
  • Corrupt Corporate Executive: Whereas his son's status as CEO of Gemn was more of a front for goals that had little to do with money making, Masamune is very much this. He views his conflict with the Riders and everything dealing with Kamen Rider Chronicle as a business venture rather than a life and death conflict with human lives on the line.
  • Creative Sterility: Despite being the CEO of a gaming company, the man seems incapable of coming up with any ideas of his own, as every single actual aspect he's brought into play has been taken from someone else in some way. Even his method of 'managing' Energy Items is incredibly simplistic and more or less consists of a book he can take them out of (which comically enough is just a repurposed prop from a different Rider series). Even before he became a supervillain, Kuroto seemed to be the one inventing all of Gemn Corp's games rather than Masamune.
  • Death of Personality: Merges himself with Gamedeus in a fit of insane desperation, giving himself a Game Over in the process. What comes out declares itself to no longer be Masamune, but it's just him doing the same thing as his son, and he's mostly if not fully in control of the resulting fusion.
  • Defeating the Undefeatable: Cronus was intentionally designed to not be something that could be defeated, so beating Masamune after he obtained Cronus' power becomes this.
  • Defiant to the End: It gradually becomes clear that the only things Masamune is legitimately good at are cultivating a good public image and doing whatever it takes to avoid losing, no matter how underhanded. After his initial period of dominance thanks to his ability to stop time unopposed comes to an end, he never reclaims a lasting advantage, but manages to keep his schemes alive well past the point where Emu could defeat him in direct combat with ease by pulling a long string of increasingly dirty tricks. While he's much like Kuroto in this regard, Masamune is far more extreme: where his son was willing to do anything to survive, Masamune is even willing to kill himself in pursuit of his goals. And then again, just to spite the heroes.
  • Dehumanization: He refers to characters by the name of the Gashat they use, rather than their human/Bugster or Rider names; for example, he calls his own son "Dangerous Zombie" rather than "Kuroto" or even "Genm". The one exception is Ex-Aid, who he refers to by his Rider name upon acquiring Hyper Muteki, but switches to calling him by the name of the Gashat when Emu can no longer use it and is thus no longer a threat to him once more. Furthermore, Masamune refers to killing people as "discontinuing" them, as shown with his Bond One-Liner to Lovelica, and his threat to Snipe and Nico.
  • Determinator: Masamune may be a horrible, monstrous excuse for a human being and a Dirty Coward, but it's really hard blame him when it comes to determination. He wants to Take Over the World and he'll do anything to achieve that goal, even risking his own life.
  • Dirty Coward: Between his abuse of Cronus' powers, refusal to let Kamen Rider Chronicle end by using extremely insane and underhanded methods, and blackmailing Hiiro into doing his dirty work, Masamune proves himself to be an unbelievably selfish and greedy bastard who is an even bigger coward than his own son.
  • Dissonant Serenity: All things considered, he's oddly nonplussed about the fact that he's been falsely incarcerated for what was basically a biological terror attack. When questioned in jail, he only expresses disappointment about Kuroto wasting his potential and his company. Later, as Cronus, the tone of his voice hardly changes, even when he's curbstomping all the Riders and Bugsters and killing Loverica.
  • "Do It Yourself" Theme Tune: The character has a theme song named "JUSTICE" sang by him. Helps that his actor Hiroyuki Takami is the singer for the legendary band Access. He also sang Kuroto Dan's theme "Wish in the Dark". He actually sings a couple lyrics of it in the series itself.
  • Driven to Suicide: After being definitively defeated, he refuses to be captured and judged by others, still clinging to his delusion of being the 'controller of lives' to his last. Instead he kills himself with the Master Gashat to prevent anyone from being resurrected purely out of spite.
  • Early-Bird Cameo: He makes a couple appearances early on to give the Riders information about Kuroto, long before assuming the role of Big Bad and becoming a regular.
  • Establishing Character Moment: Oddly enough, it's 20 episodes after his debut that his true character becomes apparent; upon appearing on the battlefield, he walks past all the riders and Bugsters calmly and unharmed, emphasizing that he's essentially invincible as Cronus and doesn't need to do much. And when addressing everyone, including his own son, he refers to them by their Gashat titles, showing that human or Bugster, he thinks of all of them as mere products of Genm Corp and little more than that.
  • Even Evil Has Loved Ones: Masamune maybe a rotten person, but he genuinely loved his wife. The reason why he never even thought of playing Zombie Chronicle to resurrect her was because it be a disgrace to her name and that she was still alive in his heart.
  • Even Evil Has Standards: As mentioned above, his love for his wife and willingness to accept her death is one of the reasons why even he finds his son to be insane with his goals, and how his own crimes don't make him any less right to stop him.
  • Evil All Along: As it turns out, he infected himself with the Bugster virus 16 years ago to be able to transform into Cronus and he was actually using Kuroto to complete Kamen Rider Chronicle while he stays in the shadows. Now that it is completed, he no longer has any reason to hide his true purpose.
  • Evil Cannot Comprehend Good: He seems sincerely unable to understand why others find his actions morally wrong or that he doesn't have the right to do what he does.
  • Eviler Than Thou: To his son Kuroto, whom he manipulated for his own ends. Though ultimately Played With. On one hand, he's undoubtly more evil than Kuroto, stronger than him, and hijacked his Evil Plan (which had already been hijacked by Parado). On the other, he's ultimately comes off as less competent than his son, with many of his plans backfiring on him and being an absolutely abysmal fighter against anyone that can get past his time skip. While Kuroto also relied on his power edge, him getting repeatedly defeat was part of his overall gambit (as the repeated deaths ultimately made him stronger in the end), while Masamune's are genuine complete failures on his part.
  • Evil Is Hammy: Must run in the family. At first it isn't apparent, but when he gains victory or an edge after his plans get derailed, he shows his rather dramatic side.
  • Evil Is Petty: His last act is to kill himself with the "Kamen Rider Chroncile" Master Gashat in such a way that he robs everyone else who died of the Bugster virus of the ability to revive, angry at the fact that beings he considered lower than him defied him and deciding that only he will be the one to pass judgement rather than anybody else.
  • Exact Words: He tells Hiiro that if he helps him out, he'll revive Saki for him from her Proto Gashat. While he does so shortly after Hiiro starts working for him, if Hiiro wants her complete with memories and all, he's going to have to keep working for him.
  • Expy: Appears to be a self-controlled version of Tenjuro Banno, as both of them manipulated their own respective sons for their endgames. Though the only difference between them is that while Banno couldn't care less about his family, Masamune deeply cared for his wife.
  • Fair-Play Villain: While Masamune is largely in control of the Gamedeus fusion, Gamedeus seems to inflict his sense of fair play on the otherwise ever-cheating villain: he doesn't finish off the heroes when he has the chance, as Nico is now his primary foe as the True Final Boss of Kamen Rider Chronicle, then proceeds to patiently wait for her to transform for some time rather than simply killing her while he had her alone and vulnerable as would be best for him, and does the same with Taiga. He also doesn't break out his One-Winged Angel form until it'd be correct for him to do so by game rules rather than just going straight to it. It's unclear if this is due to Masamune's gigantic ego, Gamedeus's programming, or some mismatch of the two resulting from their fusion.
  • False Reassurance: What He did to Hiiro to make him work by using Saki..with empty memory.
  • Faux Affably Evil: His whole motivation is done like a president of a video game company but with added shades of godhood. He has the virtues of an ideal CEO - he treats his employees well, compensates them properly, and makes sure the products the company releases are in good form. While he treats the heroes merely as products of his company, he does talk to them for a deal, and asks them to behave properly for the sake of Kamen Rider Chronicle's success (and thus his company be world-renowned with him at the helm). He does warn his foes first about calling off fights before engaging them when they relent. However, as his plans begin to go more and more off the rails, it becomes clear this is all a facade and Pragmatic Villainy: in actually he's just as, if not more, sadistic and monstrous than Kuroto was.
  • Foil: To his son, Kuroto. Both were the CEOs of Genm Corp, have massive god complexes, are steadily revealed to be far more evil than they initially appeared, and have Rider forms mainly consisting of two colors. But while Kuroto is introduced as a successful man, Masamune is introduced in jail. Kuroto becomes louder when revealing his true colors, while Masamune becomes more quiet. Kuroto's Rider form lets him come back to life anytime he wants and makes him fight in an insane and unstable manner while flailing around, but Masamune's Rider form lets him kill off anyone else permanently and ensures that he barely has to lift a finger no matter what he needs to do. Its especially apparent in how they manage Genm Corp: Kuroto developed wildly creative ideas and developed plans entirely to show his genius to the entire world, all to stroke his ego. Masamune instead focused on business, selling Kamen Rider Chronicle to the best of his ability, "buying out" competition by recruiting Kiriya and Hiiro, while working on his own plans of world domination.
  • Fusion Dance: Merges with Gamedeus to become Gamedeus Cronus. The result is decidedly not pretty. At all.
  • The GM Is A Cheating Bastard: Kuroto was never a fair player when he was running things, but with Masamune, it's worse. He regularly abuses his ability to pause time so anyone who tries to fight him can't do so much as move; if anyone has anything that can stop him, he'll take it away; when he realizes the Energy Items can help people get up to his stats, he takes them all so only he's allowed to use them. To put it in Layman's terms, Masamune never wants to play fair and will make it so he always has the upper hand whenever he can. Notably, when he's forced to play fair, he doesn't do very well at all and he has a meltdown over it.
  • Hate Sink: To an even greater extent than his son. Masamune's is basically everything one can hate about the Corrupt Corporate Executive and Sociopath tropes distilled into a person. It says a lot when Emu, the guy who was willing to think Kuroto and Parado (Though it takes time for both of them.) might actually be worth saving, questions if the guy has a soul or not.
  • Hijacked by Ganon When Gamedeus is almost beaten, he comes in and absorbs its data. As a result, he becomes the "true final boss" of Kamen Rider Chronicle.
  • Hoist by His Own Petard:
  • Humanoid Abomination: While he still looks human after merging with Gamedeus, the way he talks and the effects surrounding it makes it clear he's decidedly not anymore.
  • Humans Are the Real Monsters: Similarly to Kuroto; the Bugsters have reasonable Freudian Excuses for their behavior but Masamune doesn't. He sees everything connected to Genm Corp as company property, including his own son; and doesn't care that the lives of those playing his games are at risk.
  • Hypocrite: He despises his son for infecting his wife with the Bugster virus, saying how he doesn't tolerate nor forgive him for toying with her life... This is coming from the guy who effectively toyed with tons of lives, including using Saki as blackmail for Hiiro to do his bidding, such as trying to murder his friends, as well as denying the Kamen Riders a chance to revive those who died in Kamen Rider Chronicle, thus toying with their lives as well.
  • Hypocrite Has a Point: He actually did care about his wife enough to apparently accept her imminent death by terminal illness, rather than disgrace her memory with his son's attempts to save her.
  • The Immune: A requirement for him to wield the power of Cronus. Masamune's immunity to the Bugster Virus might be even more complete than Emu's.
  • Ironic Name: Masamune is best known as the name of one of Japan's greatest swordsmiths, whose blades were pure and believed to not destroy indiscriminately. This is not an apt description of Masamune, particularly given his habit of stealing the ideas of others rather than coming up with genuine ones himself.
  • It's All About Me: Ultimately, the success of his own ventures and desires are the only thing he's capable of caring about. Even all his talk about the good of his company is a farce: it's all just so he can Take Over the World with "Kamen Rider Chronicle".
  • Kick the Dog: When Masamune first transformed into Cronus, the first thing he did was beat the hell out of the Doctor Riders, his own son, and the Bugsters. The worst part? Giving Loverica a permanent "Game Over".
  • Killer Game Master: The apple doesn't fall from the tree, but with Masamune, it applies even moreso, since his ability to control time ensures he can do just about anything in the area and not have a single thing happen to him.
  • Lack of Empathy: He sees everyone who's not him as little more than products rather than actual people and shows no remorse or guilt in deleting Saki's data (basically murdering her) or the effect it has on Hiiro, more being angered by Hiiro not doing what he desired.
  • Laughing Mad: Come episode 42, his repeated failures have caused him to begin to be this. He goes fully into it as he's merging with Gamedeus.
  • Like Father, Like Son: As the series goes on, it slowly becomes apparent that he's not as different as his son as it may seem, and by the end, it's clear that he's just like Kuroto, but dialed Up to Eleven and without any redeeming qualities.
  • Make Way for the New Villains:
    • Takes over as the new Big Bad and hijacks Kamen Rider Chronicle by waltzing up during the apparent Final Battle with the Bugster Executives and curbstomping both sides, as well as revealing he can permanently kill Bugsters by doing so to Loverica.
    • Is on the receiving end by the upgraded Dan Kuroto in Another Ending.
  • The Man Behind the Man: Masterminded the creation of Kamen Rider Chronicle and tricked the Bugsters and his son into completing it for him. Pretty impressive, considering he was in jail for much of this time.
  • Manipulative Bastard: Having played every side for fools, Masamune openly states that his intent is to manipulate everyone to ensure that Kamen Rider Chronicle never ends.
  • Mask of Sanity: Is able to easily pretend to be a normal person and benevolent CEO to the point his workers have a very high opinion of him, but his actions after becoming Cronus shows he's a Sociopath who's anything but a sane rational human being. It begins slipping when things stop going his way.
  • Meaningful Name: One meaning of Masamune can be "True Origin", fitting given his status as the other Patient Zero. It can also mean "True Religion", fitting his gigantic A God Am I.
  • Meaningless Villain Victory: He successfully manipulates Emu into killing Parado, but fails to actually De-Power Emu in the process. Worse yet, Parado survives and the event prompts a Heel–Face Turn that leads to Masamune's situation becoming even worse.
    • The aftermath of this is actually even worse for him. He manages to reset time to a point before Hyper Muteki existed, supposedly leaving him with Graphite as the only potential threat against his Pause ability and the opportunity to rest time again if necessary. However this A) cures Nico of her second Game Disease, drastically decreasing the amount of leverage he had against the Doctor Riders B) returns the Gamer Drivers and Gashats he'd previously stolen back to Hiiro, Taiga, and Kiriya C) resets Kuroto's lives back past 90 and of course D) Dan almost immediately recreates the Hyper Muteki Gashat and comes up with a counter against Masamune's Reset ability. The only thing he has to show from all this is that he gets the Proto Gashats back into his possession.
      • Point C turns into a full-fledged Hoist by His Own Petard, since Kuroto's extra lives are instrumental in the creation of the Doctor Mighty XX Gashat that neutralizes Gamedeus' strain of the Bugster Virus. This not only saves the lives of countless people, but allows Emu to strip away a significant portion of Masamune's power, setting him up for his inevitable defeat.
      • Looking at it further, it can't even really be said that Masamune manipulated Emu into killing Parado. While Masamune simply forced a situation that pushed Emu into needing to kill Parado, Emu himself simply used the situation to engineer the Bugster's Heel–Face Turn via playing into the latter's recent fear of mortality, while having a way for Parado to survive his supposed killing. In short, Masamune got Out-Gambitted hard right there.
  • Nice Job Fixing It, Villain!: As it turns out, his Reset not only helped the heroes more in the long run, but Another Ending reveals it also undid his deletion of Saki and made her able to be restored.
  • Oh, Crap!: While we can't see his face when it happens, given his clearly visible flinch, he has this reaction upon seeing Ex-Aid activate Hyper Muteki for the first time. Although to be fair, it's pretty hard to expect your opponent to be able to move while you've frozen time.
  • 100% Adoration Rating: A rather dark and rare villainous example. He may be a manipulative bastard who sees everyone as a commodity, but the reactions of the Genm Corp employees to his return indicates that Masamune is very good at winning the loyalty of those who work for him. Of course, the CEOs in his absence having been Kuroto and Ren might have helped make Masamune look better by comparison. He helps this by claiming to his board that he has every intention to work hard to return the lives of those lost to the game, to which they applaud to. Of course, we know he doesn't really give a damn about that.
  • One-Winged Angel: In a fit of insane desperation, he merges himself with Gamedeus, becoming a Bugster. The resulting fusion has its own One-Winged Angel form, Super Gamedeus. He even comments about it as a Lampshade Hanging about Final Boss battles in video games to boot.
    • Clipped-Wing Angel: Super Gamedeus, while overwhelmingly powerful, is simply a more potent and cohesive Bugster Union. While tough enough to handle all the Riders in their most powerful forms, It's simply no match against them at Level 1 due to Level 1 being specifically meant for fighting Bugster Unions.
  • Patient Zero: Turns out, he's the other Patient Zero for the Bugster virus. Having infected himself with the virus 16 years ago, probably before even Emu.
  • Power Incontinence: After his defeat in episode 40, Masamune's stress triggers his Bugster infection to progress in similar fashion to when Emu activated Mighty Brothers XX, with the virus shown corrupting his DNA into a green and orange palette. This triggers Reset, a power Masamune didn't know he had.
  • Pragmatic Villainy: While at first he seems somewhat nicer than his son, it becomes apparent his Affably Evil facade is this trope rather than his genuine personality. Being a Benevolent Boss to his workers and a Villain with Good Publicity let's him continue "Kamen Rider Chronicle" without running into the same issues as the previous villains with the Ministry of Health getting in his way. He also goes through the trouble of making Cronus out as a character to the Ride Players, rather than actually transforming in front of them for similar reasons.
  • Reality Warper: Reset is the one power Masamune has that doesn't come from Kamen Rider Chronicle. When used, it changes reality in a way that resembles rewinding time, so that Hyper Muteki vanishes and the broken Kamen Rider Chronicle Gashat is fixed. Despite the name it's more of this trope than time travel, as only certain actions are undone:
    • Any Gashats or Drivers that Masamune willingly gave away note  remain with the people he gave them to.
    • Any Gashats or Drivers that Masamune took by force or were taken from him by force note  return to the owners they would have had if not stolen.
    • Game Disease infections and possibly the resulting Game Overs note  return to the state they were in when Hyper Muteki was first created.
    • The Hyper Muteki Gashat is erased from existence, and the Kamen Rider Chronicle Master Gashat is restored to working order.
    • All memories and events outside of the game are left intact.
    • Another Ending reveals another consequence of this: anyone Masamune rendered Deader Than Dead are no longer such and can be brought back.
  • Redemption Equals Death: His more humane side is revealed in Genm vs. Lazer, even if he doesn't live too long afterwards.
  • Redemption Rejection: Once he's lost any chance of possibly winning, Emu gives him a chance to atone for his sins and be judged by the justice system. He refuses, declares that only he may pass judgement upon the world and its inhabitants, and kills himself to leave thse who died without a method of revival just to spite the heroes.
  • Sadist: Is a sociopathic Corrupt Corporate Executive, a Combat Pragmatist Killer Game Master, AND a Faux Affably Evil Control Freak who is more than willing to abuse his authority for no reason other than playing "God". His ego is so huge, he even made Kuroto look like a saint!
  • The Scapegoat: Masamune deliberately allowed Kuroto to frame him for the Zero Day incident. This allowed Kuroto to continue creating Gashats without interruption, with the eventual goal of creating Kamen Rider Chronicle, while Masamune allowed his Bugster Virus immunity to fully mature, allowing him to wield the power of Cronus that the Master version of the Kamen Rider Chronicle Gashat would grant. As an added bonus, being in jail throughout the majority of the events of Ex-Aid provided Masamune with immunity from blame for the many, many criminal actions involved in Kamen Rider Chronicle's creation and early release, allowing him to in turn make his son the scapegoat for his own plans.
  • Sealed Evil in a Can: Has spent the last 13 years in prison. Turns out everyone was safer with him locked up.
  • Slasher Smile: He sports an absolutely monstrous one to the remaining Bugsters when they keep giving him lip in Episode 33, reminding them that they can be permanently deleted like Loverica was if they step out of line.
  • Sore Loser: The only thing that's so far managed to break through his facade is getting beat. And when it breaks, it breaks
  • Stealing the Credit: Unlike his son's vehement hatred of "bootleg" Gashats like Ju Ju Burger and Mighty Brothers XX, Masamune is all for allowing them to exist because in his opinion, it was Genm Corp's resources that made them and therefore they belong to him.
    • He does have a hatred of the Hyper Muteki Gashat, although it's more because of other reasons as opposed to being a knockoff.
    • It should also be noted that of the two Gashats he's introduced to Kamen Rider Chroniclenote , neither are an original concept. Both are simply modifications of games his son had already created and one is explicitly acknowledged as ripping off Hiiro's backstory of all things. Dan is understandably pissed off. note 
  • Take Over the World: Eventually reveals this to be his desire with "Kamen Rider Chronicle": once he gets enough people trapped in the game, he'll essentially rule everything as the one controlling all the lives ensnared by it.
  • Taking You with Me: As a final act of defiance against the Riders, he uses the Kamen Rider Chronicle master Gashat to kill himself, so nobody who died can be revived. It's not entirely successful, as the CR and Genm is looking for a way to revive the people in the Proto-Gashats, but he still hinders their efforts nonetheless.
  • That Man Is Dead: Says such after merging with Gamedeus. Unlike most examples, he seems to be speaking rather literally.
  • The Sociopath: A high functioning example, but an example none the less. Particularly given the only emotions he seems capable of genuinely showing are sadistic joy and rage when slighted (fitting the shallow emotions symptom), and him viewing everyone except himself as 'products' rather than people to the point of being willing to make them 'out of stock' without a moments regret if it suits him. He's also able to pretend to be an up standing CEO and play the system such as his son and Parado did all the set up for his plan without him being legally considered responsible for it. And of course, like his son, he has a rather pronounced A God Am I.
  • Too Clever by Half: Ultimately, his greatest weakness: he is a legitimately cunning Manipulative Bastard and The Chessmaster, but he's ultimately not as completely in control as he thinks he is, and if it weren't for managing to recruit Brave and Lazer to his side, who just happened to be in position to help him when he needed it, his time as Big Bad would've been one episode long. Recruiting Lazer also backfires on him, as he underestimated how good of a liar Lazer actually was, resulting in him swiping all the Proto Gashats out from under his nose. Not even taking control of all the Energy Items works for long, since it allows Parado to use Perfect Puzzle against him.
  • True Final Boss: Of Kamen Rider Chronicle, after hijacking the Final Boss role from Gamedeus by merging with him to become Gamedeus Cronus. He even refers to himself as such.
  • Underestimating Badassery: One of his biggest faults is he can't seem to take the heroes seriously and keeps being blindsided by their ingenuity.
  • The Unfettered: Masamune wants to Take Over the World with "Kamen Rider Chronicle", and absolutely nothing will stop him from doing so. Abusing his own son after using him as a puppet for all his life? No problem. Letting himself be put in jail for 13 years as part of his plan? Done. Blackmailing Brave by threatening to murder his girlfriend permanently? Perfectly acceptable tactic. Turning Gamedeus from a Final Boss into a sapient pandemic? Go for it! Risking his own life by injecting said sapient pandemic into himself as a last resort? He'll do it without question.It also helped him grow immune to the Bugster Virus all those years by never losing his calmness.
  • Villain Song: "JUSTICE", his Image Song which his actor also sings. Unusually, he actually does sing and hum a few lines of it in the series itself.
  • Villainous Breakdown: He doesn't take getting his butt handed to him by Ex-Aid Muteki Gamer very well. Things keep going south from there for his mental state. Seeing his plan to use Gamedeus to infect the entire world as part of his plan fails is the straw that broke the camel's back, driving him completely insane to the point he decides to make the insane move to merge himself with Gamedeus, which ends up destroying his personality and creating something much worse.
  • Villain with Good Publicity: His workers have no idea he's a sociopathic monster and he's orchestrated things such that he's not legally responsible for "Kamen Rider Chronicle", as he was in prison while his son and Parado put it into motion.
  • Walking Spoiler: Masamune only gets one scene early in the show that tells the audience almost nothing about him, and another slightly later that offers only a little more detail. Once he begins to be involved in events, he rapidly becomes one of the most important characters in the show.
  • What Measure Is a Non-Human?: He exclusively refers to Kamen Riders and Bugsters by the names of the Gashats they are linked to as he views all of them as profitable, but ultimately expendable, products.
  • You Have Outlived Your Usefulness: He's more than willing to wipe out a Bugster if they're no longer useful, as he demonstrated with Loverica and Salty.
  • You Monster!: Emu openly questions whether or not the man has a soul and Hiiro outright calls him the "cancer of this world".

Tropes exclusive to him as Kamen Rider Cronus

https://static.tvtropes.org/pmwiki/pub/images/krea_cronus.png
Ten wo Tsukame Rider! (Wow!) Kizame Chronicle! Ima koso Toki wa Kiwamareri!note  (Wow!)

  • Achilles' Heel: The button commands to activate Pause work regardless of who inputs them into his Bugvisor. His Gashat, like all the others, can be destroyed, leaving him unable to transform. And as Gamedeus Cronus, he might be an invincible being, but his bond with the Bugster isn't, allowing Level 1 Riders (who are specifically designed to break humans out of Bugsters) to sever it. Also, while his Reset can be done even if his Gashat is destroyed, he still needs his Bugvisor to do it, so if that gets damaged or destroyed, he's out of luck, and damage to it can also disable his Pause ability permanently.
  • All Your Powers Combined: As Gamedeus Cronus, he has the combined powers of Cronus and Gamedeus, and by extension the powers of all 13 Bugsters.
    • Cronus itself manifests this by being able to use and summon all Rider weapons. It's just that Masamune doesn't use this, unlike Taiga.
  • Badass Longcoat: Has snazzy coat tails as part of his suit. It really adds more gravitas and charisma into his design.
  • Chainsaw Good: Like with the previous Bugvisor, this one has a chainsaw mode.
  • Deader Than Dead: Those who got killed by him when he is using his time manipulation powers will truly disappear, even Bugsters who completed their manifestation like Loverica.
  • Deadly Upgrade: Only those with the same level of immunity and compatibility as Emu can transform into Cronus, since the Buggle Driver II was only designed for Bugsters to wear. Turns out, Masamune already infected himself 16 years ago, becoming the other Patient Zero.
  • 11th-Hour Superpower: Was intended to be this for "Kamen Rider Chronicle", as his power was supposed to be claimed in order to fight and defeat the Final Boss Gamedeus. Masamune had other plans.
  • Elite Mook: For all of Masamune's delusions of grandeur, Kamen Rider Cronus is just a souped-up Ride Player, and Super Gamedeus is just a Bugster Union on steroids, with all that entails.
  • Expy: As a Kamen Rider, his powers can be compared to Kamen Rider Odin, mainly because both have time manipulation powersnote  as well as having stats much higher than even the highest normal Rider powers in their respective series, Ryuki and Knight Survive for Odin, Maximum Gamer and Perfect Knock Out Gamer for Cronus. Both are also named after gods.
    • He's also one to Kabuto, having the power to slow and stop time and his Rider Kick being a roundhouse kick.
  • Finishing Move: Cronus has three.
    • Critical Judgement: A shooting attack using the beam gun mode of the Bugvisor.
    • Critical Sacrifice: Uses the Chainsaw Mode of the Bugvisor II to summon a giant buzzsaw of black-green energy, firing it at the opponent.
    • Critical Crews-aid: Inserts the Kamen Rider Chronicle Gashat into the Bugvisor II and a clock appears under him before he performs a roundhouse kick.
  • Game-Breaker: Played With heavily. Used as intended, Cronus isn't gamebreaking so much as it is mandatory: acquired when intended, Gamedeus would spawn under the same conditions that allowed the player to acquire Cronus in the first place, making it an 11th-Hour Superpower necessary to beat Kamen Rider Chronicle. Acquired that way, it would be used by a player so skilled and dedicated that in their hands it would truly be unstoppable. Masamune subverted the intended method of acquiring Cronus' power by building up his viral immunity before the game started, so he didn't have to reach the stage of the game where Gamedeus would normally spawn to fight him, leaving Cronus' outrageous level of power completely unchallenged and turning it into an In-Universe example of a Disc-One Nuke. However, that same cheating meant he never trained as a fighter, making him simply Unskilled, but Strong and resulting in his defeat by opponents that someone who acquired Cronus legitimately would have had no trouble with.
  • Golden Super Mode: Gamedeus Cronus turns much of Cronus gold, along with enhancing his strength and giving him access to Gamedeus' abilities.
  • Green and Mean: Has a lot of green on his suit and the biggest threat in the series currently.
  • Horned Humanoid: Kinda. He has horns on the sides and front of his helmet to form a crown.
  • Infinity +1 Sword: Is this for Kamen Rider Chronicle, being designed to be able to fight and defeat the Final Boss Gamedeus, but only acquirable by being dedicated enough to play over a decade to build up the required immunity. Unfortunately, Masamune hijacked it and doesn't want to bring the game to an end at all.
  • It Was with You All Along: A darkly villainous example. The components for bringing forth Cronus were well within the reach of the heroes for several episodes. These include a Bugvisor Zwei (which Poppy owns), the right antibodies (which Emu has), and a retail copy of Kamen Rider Chronicle (which can be bought wherever Genm Corp's products are sold, but for more proper use of this trope, is itself already owned and used by Nico).
  • Logical Weakness:
    • His Buggle Driver II naturally has to continue functioning normally in frozen time, since he couldn't do anything but move in it otherwise. As a result, a Bugster currently inside it (like Kuroto) is unaffected by the time freeze even after emerging.
    • His Reset ability returns things to what they were like at a previous point in time. This includes things he did, and thus reverts his own actions along with everyone else's, such as him swiping the Riders transformation devices and Nico being infected by the the Gamedeus Virus. Also, memories are unaffected, meaning while it got rid of Hyper Muteki, there was nothing stopping Kuroto from just making a new one from scratch since he remembered how to.
    • His Super Gamedeus form is just a supercharged version of the Bugster Unions from the very start of the show, and can be beaten the same way: use Level 1 to separate the patient from the virus. Even more logical because Gamedeus as a whole is designed to fight Ride Players and Cronus himself, who lack a Level 1 form and thus couldn't exploit that vulnerability.
  • Magikarp Power: The Kamen Rider Chronicle Gashat that lets gamers transform into wimpy Ride Players can turn them into the incredibly overpowered Cronus if they have the right antibodies and a Bugvisor handy.
  • Mascot Villain: He's the most prominent figure on the Kamen Rider Chronicle box art and cartridge label. Ironically, he's only this trope from due to Masamune hijacking it, as originally it was intended to be the Infinity +1 Sword for the game.
  • Multiple Reference Pun: He is officially spelled as Kamen Rider Cronus. However, note the pronunciation of Cronus (and thus Kronos) and Chronos being the same, and that the Greeks often confuse the two (to the point where the Renaissance has attributed the confusion to Father Time). It explains why he has time powers.
  • Nerf: Episode 38 sees Cronus introduce a book-like object which allows him to "manage" Energy Items, preventing all other Riders from spawning them and allowing him to use them whenever he likes. This is a nerf to all of the Riders to some degree, but it absolutely cripples Para-DX, whose abilities rely extensively on the manipulation of Energy Items.
  • Nothing Is Scarier: Cronus is missing two very important things: A Level for his game and his Rider Gauge.
  • Post-Mortem One-Liner: Gives one to Loverica. Too bad his enemy is frozen in time and can't hear it though.
    *after performing his Rider Kick* Tokimeki Crisis is now out of stock.
  • Purposely Overpowered: Created by Kuroto to be able to fight and defeat Gamedeus, Cronus is unsurprisingly broken beyond belief.
  • Puzzle Boss: Due to his overpowered abilities and sheer reliance on them, defeating him is less about becoming more powerful and more about finding creative ways around his powers. Such as rapid fire swapping the 10 second invincibility of the Muteki Gashat for anyone but Emu, having Emu maneuver Cronus into attacks during pause, having Para-DX use his Puzzle Gamer power to turn Cronus's own Energy Items against him, or using a Save Token to bypass his Reset power. Some tactics have more success than others.
  • Red Eyes, Take Warning: Gamedeus Cronus has red eyes, and becomes even more powerful than either Gamedeus or Cronus was alone. Notably, they also make the "pupils" narrower and have multiple red zig-zags making up the rest of the eyes, making him look even more menacing and insane.
  • Religious and Mythological Theme Naming: Cronus in Greek mythology is the name of the leader of the Titans and father of the gods. Aptly, he is the true father of the Bugster virus and Kuroto's father.
  • Spikes of Villainy: Has spikes in his shoulder pads and definitely evil.
  • Super Mode: Gamedeus Cronus, created by fusing Cronus with Gamedeus' abilities.
  • Survival Sandbox: Kamen Rider Chronicle (Master version), allows Cronus to transform into Chronicle Gamer. If the Ride-Players represent players inside the sandbox, Cronus basically represents the flipside: the ruler of the sandbox. He has powers that allows him to govern the game the way he wants it to and is basically unchallenged by anyone.
  • Swiss Army Weapon: Just like its predecessor, the Bugvisor Zwei. Though this time, Cronus can use it as a weapon and a transformation device.
    • Chainsaw Mode: Allows Cronus to use the chainsaw end of the Bugvisor to slash his enemies.
    • Beam Gun Mode: Allows Cronus to use the gun portion of the Bugvisor for ranged attacks.
  • Takes One to Kill One: Cronus and Gamedeus are designed to be Purposefully Overpowered specifically so the only thing that is capable of beating one is the other. Parado and Graphite try to get a piece of Gamedeus' code to beat Cronus, and it might have succeeded if not for Lazer Level 0's involvement. Kuroto had to intentionally create the Hyper Muteki Gashat to be on the same level as they are to give the Doctor Riders a chance of beating them.
  • Time Master: Cronus can stop time, an ability that allows him to curbstomp all the Riders and the three most powerful Bugsters. He also demonstrates the ability to turn day to night and night to day for dramatic effect, even without being transformed.
  • Transformation Trinket: The Buggle Driver Zwei and the original Kamen Rider Chronicle Gashat.
  • Unholy Holy Sword: The Power of Cronus is the only tool to defeat Gamedeus that Kuruto bothered to program into Kamen Rider Chronicle. Presumably, it would have been bequeathed to a Ride-Player determined enough to finish the game that he or she would have kept playing for at least 16 years to build the antibodies necessary to use it. Instead, it's currently being wielded by someone who wants to prolong the duration of Kamen Rider Chronicle indefinitely.
  • Unskilled, but Strong: Like his son, Masamune is overly reliant on having an edge over his opposition both in raw power and in having a broken ability to make the fight unfair. Hiiro demonstrates the ability to keep up with Cronus using only Taddle Fantasy as long as Masamune doesn't stop time, while Emu absolutely dominates him once he can use Hyper Muteki to No-Sell the time stop. Best showcased when after his Driver is damaged and he can't Pause anymore, the heroes don't even need their Super Mode forms to finish him off. While he still clearly has a power edge, unlike Parado he clearly lacks the skill necessary to take on so many people at once when he can't cheat.
  • Useless Useful Spell: Kuroto claims that the power of Cronus is the only force in Kamen Rider Chronicle that will allow Ride Players to defeat Gamedeus. He also neglected to mention that Pause is absolutely useless against said final boss.
  • Video Game Genre: As with all Gamer Riders, the Gashat he uses are based on a video game genre.
  • Weaksauce Weakness: His gigantic and overwhelmingly powerful Super Gamedeus form, while intimidating, is at its core a Bugster Union, and therefore is weak against the humble Level 1 forms that were designed to beat Bugster Unions.

Played by: Shohei Uno

A video game developer of Genm Corporation. After a scandal rocks the corporation due to Kuroto's absence, Tsukuru began working on more Gashats in order to save the company. After Dan Masamune is defeated, he becomes the new CEO.
  • Author Appeal: In-Universe and played for laughs. Apparently monks. When Taiga and Nico request a game where the player kills an immortal zombie, what does he choose? A game about a monk slaying zombies. His other idea was a monk exercise game, with Nico quickly and impatiently telling him to choose something other than monks as the basis for the Gashat they need.
  • Broken Pedestal: He once thought very highly of Kuroto, but not so much anymore after discovering his former boss's true nature and seeing him kill Burgermon.
  • Forced to Watch: He could do nothing but watch as Gemn kills his surrogate son.
  • Meaningful Name: Tsukuru means "to make".
  • Like a Son to Me: Monster of the Week be damned, this is what he feels about Burgermon.
  • Throw the Dog a Bone: After all the trouble working for Genm Corp gave him, he gets promoted to CEO and turns the company around.

Ride-Players

https://static.tvtropes.org/pmwiki/pub/images/krea_ride_player_6.png
"Enter the Game. (Whoa!) Riding the End!"
Clad in simple brown armor, these are various civilians who have bought Kamen Rider Chronicle in order to engage Bugsters in real life to win the game.
  • And You Thought It Was a Game: They all think that Kamen Rider Chronicle is just an incredibly sophisticated Augmented Reality game. It isn't and they only get to learn this after they get a Game Over.
  • Attack! Attack! Attack!: Pretty much goes for Bugsters without even trying to access power ups readily available in the playing field. The closest they get as a strategy is getting stronger weapons... before proceeding to go back to relentlessly attacking with the new weapon.
  • Beef Gate: The Bugsters to the Ride Players....by design.
  • Cannon Fodder: There are so many of them, yet they are easily outmatched by the likes of Kamen Rider Para-DX. The only one who gets around this is Nico, who acts like the only one among them who has ever played a video game before.
    • If that wasn't enough, they can't stop fighting because all of them are infected by an evolved form of the Bugster virus that isn't cured until the Bugster is defeated.
    • It also doesn't help that stat-wise, they're all weaker than the Riders' Level 1 forms.
  • The Enemy Weapons Are Better: They are armed with a measly weak sword-gun at first. In true video game fashion, they need to obtain Gashatrophies or a Rider's Gashat to gain better weapons. It also helps that it actually lets them use finishers, as their Gashat is compatible with them.
  • Freudian Excuse: After the initial run of Riders is given a game over and the Government spreads the word of Chronicle's danger, many of the successive Ride Players tend to fall under this. Though a few still treat it like a game, the majority are fighting to bring back the one's lost previously, or are already infected with the virus and see no reason to stop.
  • Let's You and Him Fight: When Ex-Aid stumbles upon the Ride Players, Poppy tricks them into attacking the Riders for "rare items," knowing the Kamen Riders can't attack innocents. After the Kamen Rider Chronicle recall, they ease back on this.
  • Master of None: Their stats are all-around balanced, but with the exception of Nico, all of them are terrible compared to the other Riders in any of their forms.
  • Power Copying: A limited subversion. If a Ride Player gets one of the Kamen Riders' Gashats, they can activate it to take their signature weapon to use for themselves...Until another player takes the weapon from their hands, since the Gashat can be used only once. It at least lets them use Finishing Move attacks with their Gashat.
  • Player Killing: They are more then willing and encouraged to beat up the Kamen Riders to steal their Gashats and weapons, though mostly because they are encouraged by the game.
  • Shout-Out: To Goombas with their color and head shape, as well as expendability.
  • Suicidal Overconfidence: Most of the first few batches of Ride Players are ridiculously overconfident in their ability to take down opponents more than ten times their level.
  • Super Prototype: They're on the wrong side of this trope. While Kamen Rider Cronus, who uses the original Kamen Rider Chronicle Gashat, is designed as the strongest Rider of all, the Ride Players and their mass-produced Gashats are worthless in battle.
  • Swiss Army Weapon: Their swords can be turned into guns (being repurposed Axel Ray Gun props from Kamen Rider Faiz), not that it helps.
  • Too Dumb to Live: All of them are at sub Level 1 stats, have no tactics, and wield crappy weapons and yet they're trying to take on enemies who are at the very least Level 10. This gets a whole bunch of them killed, and somehow, it gets even worse from there, as the surviving Ride Players A) decide that they can't and don't want to trust the CR Riders to fight Bugsters, despite knowing full well that they have far better gear and more experience than they do, and B) believe that they can overcome that by gathering enough of their numbers to basically Zerg Rush all the Bugsters, Para-DX included, until they win the game. It would have been an absolute massacre had the Riders not stepped in to save their dumb asses.
  • Working Through the Cold: Using the Kamen Rider Chronicle Gashat immediately infects the person with game disease, so they pretty much are playing while being sick.
  • Zerg Rush: This combined with the Hippocratic Oath (for Emu and Hiro at least) is the only way they can overpower a Rider.

     Saki Momose 

Saki Momose

Played by: Kana Nakagawa

Hiiro's girlfriend. She was one of the victims during the Day Zero Bugster Outbreak five years ago. When Taiga failed to defeat her Bugster Virus, which would become the Graphite Bugster, she disappeared.

Like all Game Disease victims, Saki's data was stored inside the Proto Gashat of the Bugster that had infected her, in her case the Proto Drago Knight Hunter Z Gashat. She was eventually revived by Masamune Dan as his payment for Hiiro's services. Unfortunately for Hiiro, Exact Words applied.


  • Came Back Wrong:
    • Hiiro's agreement with Masamune was to revive Saki in exchange for working for him; Masamune did so, but as previously seen with Kuroto, just reviving the person without restoring their consciousness simply leaves them as an empty shell that repeats their final words over and over. Getting that back would require additional services.
    • She comes back as a minion of Lovelica, having been brainwashed. Once he's defeated, she's freed but also can't live on her own since she was recreated using his power. She finally tells Hiiro that she doesn't blame him and would rather he forget so that he can live his life.
  • Damsel in Distress:
  • I Want My Beloved to Be Happy: She didn't tell Hiiro about her infection because she didn't want him to get distracted from his studies.
  • Kill the Cutie: Twice over, once by Graphite taking over her body and then another by Masamune when he deletes her data.
  • Meaningful Name: Saki's name is written as 小姫 in Japanese. The second character is the kanji for "princess". Taddle Legacy is about a hero saving a princess.
  • Posthumous Character: She died five years before the start of the series, and her appearances are limited to flashbacks until episode 34, when Masamune revives her body.
  • Sweet Tooth: She loves sweets, and would give Hiiro desserts while they were dating. Both he and Graphite would inherit this trait after she died.
  • Walking Spoiler: The fact that Saki exists at all is an early spoiler, while the fact that she could be revived isn't brought up until past the halfway mark.

     Jiro Maki 

Jiro Maki

Played by: Masaki Kaji

A friend of Taiga's who worked in the radiology department at the Seito Hospital and was the original volunteer for Kamen Rider Snipe. He appears in the Kamen Rider Snipe miniseries, and dies in Episode 2.
  • Back from the Dead : Revived after Taiga managed to defeat a Zombie Gamer in the Zombie Chronicle game.
  • Blood from the Mouth: His first attempt at using Proto Bang Bang Shooting resulted in this, putting him into ICU.
  • Doomed by Canon: Never appeared before in the main series, and dies to Game Disease in #2 of the miniseries. Averted in Kamen Rider Genm vs Lazer as he shown to be alive after Taiga killed a Zombie Gamer.
  • Fat Best Friend: A hefty guy and Taiga's best friend. His concern for Taiga's life costs him his own.
  • Refused by the Call: When Taiga chose to decline his place as Snipe, Maki tries to have the compatibility surgery to replace Taiga, but was deemed incompatible for the surgery. His attempt to be The Unchosen One and still transform with Proto Bang Bang Shooting resulted in the above listed Blood from the Mouth event.
  • Remember the New Guy?: Was never mentioned before nor did he ever make an appearance in the series proper. Partially justified, since he died to Game Disease and Taiga was the only witness. He does get mentioned by Emu in the final episode as one of the victims of the disease and among one of the people we shouldn't forget.
