The Low-Class Roimudes. note 

The Roidmudes are the main antagonists of Kamen Rider Drive. A group of 108 artificial life forms created by Doctor Tenjurou Banno as unique androids that were capable of 'evolving' to become more like humans. However, when their development had hit a wall, he asked his friend Krim Steinbelt for help. Steinbelt was developing a new source of energy called "Core Driviar". While skeptical of his colleague's research, Krim relented and allowed Banno to utilize the prototype of his invention in the development of the androids.

Unfortunately, upon their completion, rather than wanting to work together with humanity, the Roidmudes decided that they themselves were the superior beings and opted to rebel against them. The first act of their rebellion was to kill both Banno and Steinbelt. Then they proceeded to enact a worldwide invasion, with resulted in the "Global Freeze" incident, destroying everything in their path. But thanks to a lone hero known as Proto-Drive, their scheme was stopped at the last minute. Six months later, the Roidmudes are now in hiding and biding their time, slowly gaining more power, with the long term plan of finding the enigmatic "Promised Number" and finally annihilating the human race.


Covered in a conductive material similar to the human brain, they can evolve by copying people's body parts and physical attributes, making them more and more powerful. But their most dangerous power by far is the ability to cause the Density Shift Effect - a phenomena where everything in the vicinity is slowed down to a crawl, with the exception of the Roidmudes themselves.

    General Tropes 
  • A.I. Is a Crapshoot: They're androids, not A.I.s, but the trope fits. Later on, its revealed that Banno purposely made most of the Roidmudes evil to begin with, so this trope is Averted.
  • Animal Motifs: The basic Roidmudes are segregated into categories based on this trope:
  • The Assimilator: They evolve by copying appearances and memories from actual humans. Death of the one copied not required, but some Roidmudes do it anyway.
  • Blank Slate: All Roidmudes start as this. They are designed to evolve by absorbing knowledge and information, upon with they start to form a personality. If they become unruly and jeopardize the Roidmude objectives, they will be hunted down and returned to this state by Brain.
    • As it turns out, this is why they're bad. Banno uploaded dark human emotions into them, which influenced many of them to become violent upon maturity. Had he not been there, it's likely they would've been much better.
  • Les Collaborateurs: Overlapping with Humans Are the Real Monsters, Neo Viral Core hosts willingly choose to side with the Roidmudes.
  • Color-Coded Characters: Heart, Brain and Chase wear clothes that are the same color as their Roidmude (or in the case of the latter, Mashin Chaser) forms.
    • Colour-Coded for Your Convenience: Each Roidmude's power has a different color. This is most notable when they change forms.
    • Some of them have body parts that are in a different color from the restnote .
    • The Executors who appear later, Medic and Freeze, don't seem to follow this pattern, though. Medic is an Elegant Gothic Lolita dressed in black while Freeze is often seen wearing a green coat over a brown suit, but their Roidmude forms are yellow and red and a light blue respectively.
  • Death Is Cheap: It used to be. Heart was hoping that the revival of Medic would make it so once more, but she wound up being terribly disinterested in healing Roidmudes weren't him.
  • Defeat Equals Explosion: Standard fare for toku monsters, but they take it one step further. Whenever a destroyed Roidmude's body goes kaboom, all that remains is a Core. If Drive dealt enough damage, that will go boom as well. In other words, Roidmudes explode two times in a row.
    • Weaponized by Chase, who after being mortally wounded by Banno, tackles the Mad Scientist and holds onto him until the explosion happens.
  • Disc-One Final Boss: While they're the overall villains and are still antagonists, it becomes clear that they're nothing compared to their inventor.
  • Early-Bird Cameo: As there are a finite number of Roidmudes, several of them that later become Monster of the Week can be seen first during the Global Freeze, albeit in their unevolved form... though you'll have to squint your eyes really hard to deduce which one is which.
  • Evil Knockoff: Roidmudes who copy humans get both their appearance and personality traits, becoming warped versions of those humans.
  • Expy: They share many similarities with the Worms, what with the Mooks getting the option to evolve into the Monster of the Week, the Slowdown concept being the inverse of Clock Up (here effecting everything but them normally), and the ability to take human form. Some of their traits are like the Orphnochs and Natives, who wants to live in a normal life instead.
    • There's also similarities with the Inves - Mook form variants (colors instead of animal types), relying on some MacGuffin (Lock Seeds and Viral Cores) to evolve, either to a Monster of the Week, a sentient commander (Overlords or the Executors Heart, Brain and Medic) or One-Winged Angel level. Instead of Helheim, they bring their home ground advantage with them by inducing Slowdown.
    • Androids who start off normal, but after a little bit of negative influence turn evil? Sounds very similar to a Reploid going Maverick.
  • Fantastic Racism: It goes both ways as after Freeze's defeat, laws are put into place that makes even associating with a Roidmude a punishable offense.
  • From Nobody to Nightmare: Well, from a lesser Nightmare to a bigger one, but still. All major Roidmudes like Heart or Brain started out as basic Low-Classed ones, having evolved into much more powerful forms.
  • Finger Firearms: Minor Roidmudes' basic form of attack.
  • From a Single Cell: So long as their Cores are still intact, they can resurrect after some time with the help of a Viral Core. But if it's destroyed, they're gone for good.
  • Four Is Death:
    • Heart eventually reveals that their "Promised Number" is four, meaning if four Roidmudes achieve Super Evolution then they can trigger a second, truly worldwide Global Freeze.
    • This trope is present for 004 as well; for more details, look at his entry.
  • Golden Super Mode: Their super evolution gives their bodies a golden color, as shown with Freeze, Brain, Heart, and Medic.
  • He Knows Too Much: Besides wanting to atone for the fact that his father created them, Gou wants them all dead lest one of them accidentally (or intentionally) tells Kiriko that Banno was the one who made them.
  • Hidden Agenda Villain: In general the Roidmudes pursue their own desires, but Heart and Brain have been tasked with gathering Roidmudes with unique powers in search of something called the "Promised Number". And apparently they're on a time limit.
  • Humans Are the Real Monsters: This theme becomes more prominent with the Neo Viral Cores. Their arrival causes humans who were already evil criminals to take part in the plot and as a police officer Shinnosuke is tasked with arresting them, not redeeming them.
    • Towards the end of the show, it's revealed that Banno caused them to become violent due to altering them while they were being born, meaning that if not for his evil plans they could've lived in peace. Shinnosuke even says in the finale that the true evil was the darkness in humanity's hearts, not them.
  • Meaningful Name: The name Roidmude comes from combination of the words "Android" and "Mutant".
  • Mechanical Evolution: Roidmudes are, as stated above, mutant androids. Their purpose is to copy the data of humans in order to develop and mature based on that data.
  • Mooks: Despite there being a limited number of Roidmudes, several of them serve this role.
  • Moral Myopia: On the Global Freeze, they tried to wipe out humanity, and yet they have a hatred of Drive for killing their kind in retaliation. It's not until later that they had a good explanation for why human lives didn't matter to them.
  • No Biological Sex: Being robots, Roidmudes don't have sexual characteristics. Those who copy human forms and take on their personality traits begin to identify as the gender of their chosen target, but could change these forms at will.
  • One-Winged Angel: If a basic Roidmude will use 3 Viral Cores, he will become a gigantic, animal-shaped mecha-beast known as a Giant Roidmude.
    • If an Advanced Roidmude does it, they use 2 Viral Cores, but they have a chance of escaping certain death and devolve back into their original form.
  • Phlebotinum Rebel: A twist on the usual Rider standard. Their power comes from Core Driviar engines, the same system originally meant to power the Shift Cars and Tridoron, which is also the reason they can cause Density Shifts.
  • Psycho for Hire: Due to the nature of Neo Roidmudes, their choice of human hosts have all been psychotic criminals.
  • Psychopathic Manchild: An entire race of them. Roidmudes evolve by mirroring a human, thus they childishly base their actions off of the human, leading to this trope to happen. Thus, a Roidmude who based himself off of a stalker develops stalker tendencies, while another Roidmude who based himself on an otaku becomes an almost completely harmless otaku himself.
  • Rule of Three: There are 3 types of Viral Cores: regular Viral Cores for evolving Roidmudes, Chaser Viral Cores for giving Mashin Chaser his armaments, and Neo Viral Cores, which allows a Roidmude to evolve by fusing with a human.
    • This also applies between individual Cores or Roidmudes, any of which can be Cobra, Spider, or Bat.
  • Skull for a Head: No you are not imagining it, all Low-Class Roidmudes' heads have what look like human skulls for heads, or at the very least, the parts above the nasal cavity.
  • Stronger with Age: If Heart is to be believed, Roidmudes get stronger as they live longer. They are supposed to be self-evolving.
  • Super Speed: Even without using Density Shifts, many Roidmudes can run so fast on foot that the Riders need to use their vehicles to catch up to them.
  • Time Stands Still: They all have the power to induce "Slowdown"/"Density Shift", which causes time to get all wonky for everyone except themselves, Drive and anyone in possession of a Shift Car.
  • Tragic Monster: While they are dangerous, and have caused hundreds, if not thousands, of deaths, ultimately, Banno's abuse made them what they were, and there are implications that had things been different they could have lived in peace with humanity.
  • Turned Against Their Masters: The first three Roidmudes rebelled against their creator. But it was actually his set up along and letting them kill him after stealing Krim's mind uploading tech, plotting his evil plan in the shadow without the Roidmudes knowing.
  • Voluntary Shapeshifting: The Roidmudes can change their form at will.
  • Winged Humanoid: Bat-type Roidmudes can sprout wings out of their backs.
  • You Are Number 6: Their true form is literally nothing but floating numbers. Roidmudes that haven't yet evolved are referred solely by their number. Once they evolve, they are referred to by their motif. Some prefer to go by their numbers even after evolving, such as 001, 006, and 008; with the latter two doing so to keep their powers a secret.


002 Heart Roidmude/Kamen Rider Heart

Portrayed by: Tomoya Warabino (live), Yohei Fujita (suit)
One of the first Roidmudes and their de-facto leader. He greatly cares for his fellow androids, treating all of them like friends. That empathy however hides a bloodthirsty killer, who will risk his own life to destroy those opposing the Roidmudes. Together with Brain and later Medic, he plots the uprising against mankind.
His most fearsome ability is being able to enter a state known as "Dead Zone", where he gets stronger and stronger at the risk of exploding.
  • Abusive Parents: The way he talks about his former relationship with his creator Banno just screams of this trope.
  • Achilles' Heel: His heart, of course.
  • Affably Evil: He's rather polite and chill, seeing all of the Roimudes as his friends. In episode #38 he even states that he's never really thought of himself as evil, and Shinnosuke actually agrees with him.
  • All for Nothing: In the end, all his attempts to free his kind by violent revolution accomplished was every Roidmude except himself dying and playing right into the hands of the very one he was rebelling against.
  • Antagonist in Mourning: He takes the destruction of his fellow Roidmudes hard, even worse when he believed Chase was dead. He's the only one of the Roidmudes whom actually cares.
    • Did not take it well when Freeze killed Shinnosuke. Though, it was more for the fact Heart wouldn't reach his own Ultimate Evolution with Shinnosuke gone.
  • Anti-Villain: He's not really your typical Tokusatsu main villain. He's rather polite to just about everyone, He very rarely if ever gets angry, and he genuinely cares for the well being of his subordinates. And as episode #38 reveals, he doesn't even consider himself to be evil, and even shows a great deal of honor by refusing to kill Shinnosuke because he can't fight back. Keep in mind that Shinnosuke is responsible for the deaths of about 50% of the Roidmudes
  • Arbitrary Skepticism: In the Shuriken Sentai Ninninger crossover, he doesn't believe Brain telling him that he sees giant robots when his entire race is made up of killer time-stopping robots that can also mutate into giant robots.
  • Arch-Enemy: Of Banno.
  • The Atoner: After being resurrected in "Saga", no longer wanting to see the Roidmudes harming people as they once did.
  • Authority Equals Asskicking: By far the strongest opponent Drive has faced, even managing to defeat Type Wild easily in the power department and just keeps getting stronger by the minute.
  • Back from the Dead: Is accidentally resurrected by Gou in the "Drive Saga" specials an attempt to resurrect Chase. Fortunately, Heart is tired of the fighting and makes a Heel–Face Turn.
  • Badass Longcoat: Most noticeable in his human form, though as a Roidmude he still has traces of it.
  • Big Red Devil: His Roidmude form definitely takes some cues from the Devil.
  • Black-and-White Morality: A villainous example. Heart sees all humans as evil and all Roidmudes as good.
  • Blood Knight: More subdued when compared to Phoenix and Deemushu but it's there. In fact, the emotion Heart copied from humans was Joy, and he admitted to Chase the thing he feels most passionately in the heat of battle is Joy.
  • Breakout Character: Heart's popularity got him his own special where he becomes a Rider.
  • Broken Bird: It is eventually revealed that his torment at the hands of Banno has left him very, very broken on the inside.
  • Deconstruction: Even more than Chase, Heart is what a Rider would be if they were truly on the bad guys' side.
    • Determinator: He won't stop until humanity is enslaved and Roidmudes are on top of the food chain.
    • Heroic Willpower: The Dead Zone lets him boost his strength high enough to fight Drive head on even at the risk of high damage.
    • Power of Friendship: He wants revenge more and more every time another one of his Roidmude pals gets done in.
    • Protagonist-Centered Morality: As far as he's concerned, he and the other Roidmudes are just fighting for their proper place in the world, and that humans and the Riders are the evil ones.
    • He's also been the subject of cruel experiments like the first Kamen Rider.
    • Reconstruction: Ultimately comes full circle when he teams up with the heroes in the last episodes and eventually becomes a Rider himself in Kamen Rider Drive Saga: Kamen Rider Heart.
  • Contrasting Sequel Antagonist: To Rosyuo and Kaito from Kamen Rider Gaim. While he shares their color schemes and their statuses as leaders of inhuman armies, Heart is (often to a fault) an optimist who cherishes and trusts his villainous subordinates instead of viewing them with contempt and suspicion.
  • Disc-One Final Boss: Is the Big Bad for most of the series, but ultimately ends up booted out of this spot by Dr. Banno once the maniac escapes.
  • The Dreaded: The first time he showed himself to Shinnosuke and co., Mr. Belt opted to tell Shinnosuke to retreat rather than fight him.
  • The Dragon: At first he's this to Freeze, although he seems to give the commands at first glance...then Freeze steps into the picture and Heart more or less lets him lead.
  • Enemy Mine: More than willing to ally with the Riders against Banno, though he still insists that he should be the one to kill the guy.
  • Et Tu, Brute?: This is how he reacts to Brain and Chase agreeing with Angel's plan for the Roidmudes.
  • Evil Virtues: He genuinely cares for his fellow Roidmudes, considering them all his friends. That Drive is running around killing them drives him into such a fury when they finally clash that he's willing to risk burning himself out if it means destroying Drive in the process.
  • Explosive Overclocking: The source of his overwhelming power, known as the Dead Zone. Using it gives him a huge power boost, but puts him at a serious risk of self-destruction. However according to him, since Medic not only healed his earlier damage, but strengthened him, this flaw might no longer be a concern.
  • Eyeless Face: Heart's Roidmude form has no eyes, unless the space between his horns and scalp are his "eyes".
  • First Of Its Kind: Episode #40 revealed that he became active before 001, if only as a torture subject for Banno.
  • Freudian Excuse: His creator basically made him to let himself torture someone with the face of a person he hated. Is it any wonder he hates humanity after that?
  • Forced into Evil: Well, he was pretty evil already, but Banno blackmailed him into service in order to save Medic. Once Medic's safe, they pull an Enemy Mine with the Riders.
  • Heel Realization: After the reveal that Chase's brainwashing was due to Heart in the first place, him mourning the Reaper's death and accepting his joining the heroes can be taken as a slight case of this.
  • The Heart: Ignoring all the obvious jokes that come from this, he is very much this in his own way, viewing the Roidmudes as friends and family and wanting them to work together. Case in point, he's the only one truly mourning Chase's death. Brain is really only pretending to get back at Medic. He is also the only one programmed with a "positive" emotion, compared to his comrades.
  • Hero Killer: He's the Roidmude who took Krim Steinbelt's life. Ironically, his rescuer who saved him from Banno's abuse.
  • Heterosexual Life-Partners: With Brain & formerly Chase, though Brain isn't exactly heterosexual.
  • Hot-Blooded: He admits that when the blood starts pumping, he has trouble quieting down.
  • Honor Before Reason: He does admit that he could easily kill Shinnosuke untransformed, but he feels it isn't worth it, as the point of his revolution to surpass their creators, not simply win against them. Also, see Worthy Opponent below, where the key to his Ultimate Evolution is Shinnosuke.
  • I Owe You My Life: Why he's so insistent on reviving Medic and why he's so forgiving of her more psychopathic proclivities.
  • Last of His Kind: by #46, he is the last living Roidmude.
    • Or at least was.
  • Locked Out of the Loop: For much of the series, he has no idea why Brain and Medic hate each other and doesn't know of Medic's aspirations for genocide.
  • Moral Myopia: Heart values the lives of Roidmudes over humanity, much in the same way humans would animals. He sees whatever they do against them as righteous but the reverse a heinous crime. He also feels justified in sending Chase after uncooperative ones since he can't actually kill them, and wishes them a better next life.
    • His viewing Chase as a close friend becomes this in #30, where it's revealed that not only was he aware of Chase's brainwashing, but it was his idea and he helped perform the operation personally...while Chase was still alive and conscious. As soon as Proto-Drive was on their side, though, Heart considered him a good friend.
  • Mr. Fanservice: Already a fairly good looking man, Episode 11 goes one step beyond by having him shirtless.
  • Noble Demon: Has a lot of honor despite being a Roidmude. Mourning for his friends when others would just scoff or label them as failures, and even allowing Chase to make his decision on whether he'll be fighting for them or the Riders instead of just grabbing him and dragging him to their base for further brainwashing when Chase shows serious conflict of who he should fight for and then taking the news, although sad about it, rather well.
  • Number Two: Literally, as he is labeled as 002 after it was heavily implied. However, Heart is still the leader of the Roidmudes, as 001 believed Heart was the most suited for the role.
  • Official Couple: With Medic, much to Brain's displeasure.
  • Orcus on His Throne: Waits till #10 to get a piece of the action, and shows us why it took him that long to get active.
  • Pet the Dog: The first thing he did to 041 when Medic experimented on it was to heal away its side effects.
  • Psychopathic Manchild: An aversion compared to the rest of his race. Heart is actually very mature, which is probably why he's in charge.
  • Red Is Heroic: Played with. Heart usually wears a red outfit, has a red coloration as an Advanced Roidmude, is one of the least villainous Roidmudes, and certainly the most genial of them. His Enemy Mine situation with the heroes in the final episodes pushes him closer to this trope, and he lands squarely in it when he becomes Kamen Rider Heart.
  • Red Oni, Blue Oni: Normally acts as the blue to Brain's red, until he gets angry and inverts the relationship.
  • Rival Final Boss: Subverted. As much as he wants to become this, he can't on the account of his fatal wounds and Shinnosuke acknowledges this.
  • Skull for a Head: Unlike other evolved Roidmudes, who forgo their skull heads during evolution, Heart still retains his a la Havik.
  • Super Mode Battle Aura: "Dead Zone", a red lightning charged aura that is responsible for Heart's power.
  • Superpower Lottery: Because he was one of the first Roidmudes activated, Banno neglected to program a strong negative emotion into him, so while his fellow Roidmudes have to pursue painful states of being such as Envy and Humiliation, Heart gets stronger the happier he becomes. In fact, the only reason his evolution is inhibited is due to how his past abuse at his creator's hands scarred him mentally and the fact that the death of each of his fellow Roidmudes weighs heavily on his spirit.
  • Token Good Teammate: Of all the Executives, he is the only one who cared for other Roidmudes. He is also the most polite, respected Chase's new decision to defend humanity, and opposed Medic harming other Roidmude when he finally found out.
    • It's taken even further when it's revealed that, aside from Chase, he is very likely the only Roidmude who hasn't had negative emotions deliberately programmed into him by Banno, or corrupted by their own powers like Medic.
  • Transformation Is a Free Action: Averted. When Heart is about to transform to fight Drive, Mr. Belt calls the Tridoron to shoot him down and escape.
  • True Companions: Oddly for a villain, he believes in this trope, seeing all of the Roimudes as his friends. Meanwhile, he seems to have a special fondness for Medic.
  • Unstoppable Rage: The loss of his fellow Roidmudes drives him to manhandle the Riders when he fights them, even risking using his powers that could very well kill him as long as he gets the chance to take Drive down with him.
  • Villain Forgot to Level Grind: Averted; Mr. Belt says that Heart has grown stronger since fighting Proto-Drive. #37 reveals averting this is his actual power - when an opponent hits him with their strongest, he analyzes it and automatically surpasses it.
    • This trope is played much straighter when Heart faces Drive in his Dead Heat form.
    • Then subverted in his fight with Kamen Rider Chaser due to finding power from his key to his Ultimate Evolution.
    • Subverted again once he gets the ability of using Super Slowdown, making any type except Formula, Dead Heat, and Tridoron useless. Even without it, by #37 he can beat Type Tridoron in a no-holds-barred fistfight, even overcoming Drive's Rider Kick with a punch.
  • Villainous Friendship: With all Roidmudes, to where, with less than 70 Roidmudes left after #25, he sounds pretty mournful at how quiet it is with the lack of his friends.
  • Villainous Valor: He's willing to sacrifice his life to kill Drive so the Roidmudes can complete their revolution.
  • Villainous Rescue: A Heroic Sacrifice example to save the Riders from a brainwashed Medic, then had himself abducted by Gold Drive and later Forced into Evil temporarily to save Medic and get along with his play, until Brain's sacrifice to save Medic's life.
  • Visionary Villain: Heart sees a world where the Roidmudes have supplanted humanity and have evolved into a better species.
  • We Have Reserves: Notably does not believe in this. He genuinely cares about his kind and hates anyone who kills one of them. He gets flat out furious at Medic for having this mentality, to the point of saving the mook she was about to let get killed before chewing her out.
  • The Worf Effect: Heart's no pushover, but all of his major battles serve to stress the newfound powers of the heroes (and rival villains).
  • Worthy Opponent: Begins to see Drive as this after his defeat at the hands of Type Dead Heat. To where he is not glad that Freeze apparently killed Shinnosuke, but aggravated, since Heart believes Drive is the key to his Ultimate Evolution.
  • Why Don't You Just Shoot Him?: Played with. Heart is very aware that he could very easily go find Shinnosuke and company and just end them, but he doesn't have any interest in doing so, and writes off the chance the minute Brain suggests it. #33 reveals why - see Worthy Opponent above.
  • Yakuza: Heart comes off as something of a gangster.

Tropes exclusive to him as Kamen Rider Heart
Drive: Type Speed Wild Technic!
Drive: Type Miracle! Heart the Kamen Rider!

  • All Your Powers Combined: His Shift Heartron Shift Car allows him to perform a "Viral Blending", allowing him to access Brain and Medic's powers along with his own.
  • Cast from Lifespan: Brain admits that by allowing access to his full power as Type Miracle, through fusing his own and Medic's Cores into the Driver, none of them are going to survive afterward. Heart admits he's fine with this, because at least they'd be dying together this time.
  • Finishing Move: Heartdrop: Kamen Rider Heart enters the Dead Zone, then focuses its power into his right leg before performing a flying kick at his opponent.
  • Foil: Drive Saga: Kamen Rider Brain makes him one retroactively to...Kamen Rider Brain. While he transforms with a Shift Car and Drive Driver, his forms are based off of Kamen Rider Drive's own forms, and he had his own "Mr. Belt" in the form of his fellow Roidmudes Brain and Medic. Kamen Rider Brain, however, transforms by simply turning the Advanced Igition on his modified Banno Driver, his sole Kamen Rider form shares the same aesthetics as Gold Drive, and he's aided by Chystal Peppler, a human scientist who looks suspiciously like Krim Steinbelt. While Heart fights hand-to-hand with his full strength restored, Brain possesses his own unique gear, including a Sunglasseslasher recolor and his handkerchiefs.
  • Fusion Dance: Visually, his Type Speed Wild Technic is one between all three of Drive's basic forms, and his Kamen Rider Heart form is one between his Heart Roidmude form and Drive Type Tridoron. Notably, Brain and Medic had to personally fuse their Cores into the Drive Driver Heart wore to access Type Miracle, so it can also be considered a fusion of the Power Booster variety.
  • Joke Character: Type Speed Wild Technic is this, as a result of Heart's new body limiting his full power and Brain rapidly compiling the data of Drive's battles while in the heat of battle against Roidmude 5886.



003 Brain Roidmude/Kamen Rider Brain

Portrayed by: Shouta Matsushima (live), Daisuke Satou (suit)
A high-ranking Roidmude and Heart's partner. As his name indicates, he is extremely logical - which causes him frustration when others around him are more emotional and don't follow or appreciate such logic (which is most of the time).
  • Ain't Too Proud to Beg: He outright begs for his life when Medic demonstrates her new brainwashing techniques by ordering Chase to kill him, something Chase would otherwise never do. He also approaches 001 for help when he realizes he simply cannot keep up with Medic's level of ruthlessness, and how it's basically made him a joke. Subverted in #44. He begs for his life again when Banno sends Medic to capture him, but this time he's pulling an I Surrender, Suckers to get close to Banno.
  • Always Second Best: How he feels about Medic. Made no better on how when she returns she becomes Heart's right hand as well as her seemingly doing his job better and with more results.
  • Ambiguously Gay: Given his interactions with Heart, all he's really missing is openly identifying as such.
  • Badass Cape: In his Roidmude form.
  • Bad Boss: Let's just say Brain was not happy with Chaser when he let Drive go to Volt...
  • Big Bad Duumvirate:
    • Leads the Roidmudes along with Heart. However, once Medic enters the picture he feels like he's getting demoted.
    • He later briefly becomes a villain duo with Nira.
  • Breakout Character: Strangely, he managed to get his own special and become an official Kamen Rider four years after the end of his series, albeit a comedic one.
  • Butt-Monkey: Probably because when he retreated into the CIA during the Global Freeze, the guy he copied wasn't exactly calm.
  • Character Development: A rather dark take on this trope, and one purposely Invoked by 001, who's encouraging Brain to take advantage of his recent Villain Decay and Butt-Monkey status to spike up his negative emotions to new levels to reach a higher point of evolution.
  • Characterization Marches On: In early episodes Brain was on even footing with Heart, even criticizing his decisions. Compare that Brain to the one who is completely devoted to Heart's existence and you"ll wonder what happened, even before he became Medic's bitch.
    • Character Rerailment: 001 helps him get back on track, to the point that he and Nira use carefully constructed half-truths to frame the Special Crimes Unit for treason. It doesn't last, with him getting knocked back down by the Riders.
  • Death of Personality: He can "reset" a Roidmude's personality. With help from Prof. Banno.
  • Demoted to Dragon: After getting fed up with the lack of progress under Heart and Medic's direction he goes to 001 for help and becomes his subordinate. This has strangely gone well for him, as he's regained a lot of his former menace and competence... for a while anyway.
  • The Dog Bites Back: After obtaining his Super Mode, he takes great pleasure in giving Medic a beatdown for how she treated him. She returns the favor after the Riders kick his butt and reduce him to just a core.
  • Dying Moment of Awesome / Heroic Sacrifice: Dies sacrificing himself to free Medic from Banno's control, depriving the latter of his blackmail material over Heart; allowing both to ally with the Riders against Banno.
    Brain: Did you forget, Banno? My name is Brain... it means I have the intelligence to thwart your plans!
  • Even Evil Has Standards: As rotten as he is, he's suitably horrified to see Banno destroy 006's core and steal his body.
  • Evil Genius: He's the smartest of all first.
  • Envy: 001 reveals that this is the unique emotion that helped trigger Brain's evolution, like Heart's Joy, Medic's Lust, and Freeze's Humiliation. He also evolved into his Super Evolved State because of Nira's envy against the Tomaris.
  • Famous Last Words: Capable, loyal, and...
  • Hypocrite: Brain believes he's a completely logical being, but all of his motives are later driven by the emotion of envy.
  • Heel–Face Turn: Was told by Heart that they are created to follow Banno, suggesting him to escape. After Heart and Medic are abducted, he felt sad for Medic's twisted personality for syncing other Roidmudes' memory syncs while healing their physical body. While trying to find a new life as a human, Brain is now on the run from Gold Drive and under protection of Special Investigation Division, until he "surrendered" himself, to save Medic and Heart, and Gold Drive's play.
  • I Am Not Left-Handed: Invoked on his part. He continues to use the Thief Roidmude form for a while until he's able to do cheap shot at Kamen Rider Drive by the time he's ready to reveal his Ultimate Evolution.
  • I Want My Beloved to Be Happy: The reason he Took The Bullet for Medic believing that out of the two of them, Heart cared more for her.
  • I Surrender, Suckers: He stopped running from Banno and went back to screw up his plans from the inside.
  • Irony: Brain has shown much more emotion than Heart. Heart is calm while Brain constantly voices his irritation at his lesser-evolved comrades for mostly being reckless and overall stupid.
    • Fridge Brilliance: Of course, since Heart's theme is emotion, while Brain's is logic, this shouldn't surprise anyone. He literally cannot comprehend anything other than logical solutions.
  • Green-Eyed Monster: He becomes intensely jealous of Medic when she appears to be taking his spot in everything he used to do; as Roidmude leader, Heart's confidant, and Chase's reprogrammer. Justified in that the emotion he draws power from is Envy.
  • Kleptomaniac Hero: Villainous version; he twice stole tablets from bystanders to get computer access; once at the series premiere and again near the end of the series when on the run.
  • Killed Off for Real: In #44.
  • Knowledge Broker: Keeps tabs on all Roidmude activities.
  • Made of Iron: Gets hit with a triple Rider Kick performed by Chaser, Deadheat Mach, and Drive Type Tridoron; and while it destroyed his body, his core survived. Compare this to Freeze, who was killed off by just Type Tridoron's Finishing Move.
  • My Brain Is Big: Sports a pretty impressive noggin' in his Roidmude form, topped with what looks like a giant pan. So you could say he has an enormous brainpan.
  • My God, What Have I Done?: After seeing Medic be brainwashed thanks to him helping Banno.
  • Nice Job Fixing It, Villain!: In his desire to undermine Medic's position he weakens Chase's firewall which leads to Medic's plan to kill the Kamen Riders to fail which if he didn't, would have succeeded. Medic calls him out on this.
  • Not So Above It All: In episode 17 he overhears Heart and Medic talking. Brain berates himself for eavesdropping but still listens anyway. Then he goes into a jealous rage over how close Medic is to Heart.
  • Oh, Crap!: After witnessing Banno killing 006's core and stealing his now-empty body, as well as Gold Drive's power and ability to steal the Riders' weaponry, Brain tries to get away as fast as he can. However, the dog he's looking after pees on his feet, he screams in frustration - before realizing that he just alerted Banno to his presence.
  • Only Sane Man: In Episode 16, he figures that Drive has some connection to the Metropolitan Special Unit. When he brings up his concerns, Heart and Chase both say they don't care about Drive's secret identity, and Medic calls him petty. Brain feels like the others are ganging up on him.
  • Opportunistic Bastard:
    • He doesn't hesitate to try to return to Heart's favor as he's mourning Chase or successfully achieving his Ultimate Evolution.
    • Second time in #34 when he was about to leave Nira to be arrested when he overheard his jealousy.
  • Poisonous Person: A decent surprise, considering his motif. Brain has the power to create a powerful neurotoxin, as Shinnosuke and Gou found out the hard way.
  • Power Glows: His brain glows when making his neuro-toxin.
  • Pragmatic Villainy: Unlike Heart or Chase, Brain won't hesitate to take advantage of any weakness Drive or anyone else of his enemies shows. For example, when Shinnosuke confronts him in Episode 31 without his belt, Brain notes that while Heart would give him time to get the belt and transform, Brain himself sees to reason to do so. He does not, however, opt to go through with his original idea of going after the Metropolitan Special Unit despite now working as 001's subordinate and a special advisor to the police, simply because there is no longer a need to.
  • Psychic Powers: Gains a number of these upon gaining his Super Mode.
  • Red Oni, Blue Oni: Red to Heart's blue, unusually for their motifs. Heart is usually the more laid-back of the two, while Brain is uptight and irritable.
  • Rule of Three: When he lists things against someone, he'll make sure to use three words to describe your performance. Or when he's particularly vexed, which is often.
  • Security Blanket: His handkerchief. Whenever he is nervous, he will use it to calm himself down. When Medic burns it, he screams in terror.
  • Sesquipedalian Loquaciousness: He's a very big fan of this.
  • Slasher Smile: Highly misleading; his monster face is frozen in what appears to be a mild version of it. Moving close up to it reveals his "teeth" is actually his lower lip.
  • The Spock: A deconstruction. Brain is intelligent but he doesn't get people, which the others point out makes him a lousy planner.
  • Surrounded by Idiots: Is increasingly annoyed that the more reckless Roidmudes are evolving. He also can't comprehend why his peers are not as pragmatic as he is either.
  • This Cannot Be!: Brain was flummoxed by Iron's destruction and death.
  • Tomato in the Mirror: While on the run from Banno, he coincidentally winds up in the place where he copied his first human form from and after a bit of research into exactly who it was he copied, he finds out that everything from his fondness for glasses and handkerchiefs to his desire to be the best and most favored subordinate possible was lifted wholesale from the human whose face he duplicated.
  • Verbal Tic: He has a habit of listing things in threes. Tragically his Famous Last Words get cut off by his own death, leading Heart to beg him to tell him what the third thing he was going to say was.
  • Villain Decay: Originally portrayed as a Evil Genius smart enough to just kill Drive, Brain slowly degrades into a joke. The other Executors call all of his plans stupid, he loses all respect, and then he's reduced to Medic's bitch in #22 when she burns a handkerchief that was used for gags and this act sends him to tears. It gets worse in #25 because Medic and Heart realize that Roidmude 001 has resurfaced because they both agree that Brain is too incompetent to make a Neo Viral Core. Eventually manages to reverse this with 001's help. And obtaining his Super Mode. But it's only temporary.
    • From Nobody to Nightmare: He briefly reverses this while partnered with Nira, coming closer than anyone else does to not only killing Shinnosuke but destroying his reputation and that of the entire Special Crimes Unit. Unfortunately for him it doesn't last.
  • Villain Override: Can take control of electronics to do things like track other Roidmudes. He can hack into other Roidmudes too, but generally doesn't.
  • Wounded Gazelle Gambit/Police Brutality Gambit: This is how he takes Shinnosuke out of the action in #27. He poses as a higher-up police officer long after Shinnosuke knows of his human guise and pushes his Berserk Button just enough to have him flying into fury right as he assumes said guise when other police officers come.

Tropes exclusive to him as Kamen Rider Brain
Start Your Engine! Brain the Kamen Rider!
  • All Just a Dream: Ultimately, his time as a Kamen Rider was a dream Brain was having.
  • Calling His Attacks: Really indulges in this in his second fight with his Rider Poison Hand and Poison Handkerchief, and his Brain Head Crusher Finishing Move.
  • The Cameo: Appears as one of the Riders summoned by the power of Zi-O Ohma Form in Over Quartzer.
  • Cool Bike: Is shown driving the Ride Braiser,...which is a redesign of Chase's Ride Chaser.
  • Cool Sword: His Brain Megane Blade, which is a green recolor of the Sunglasseslasher. Lampshaded by Dark Ghost's last words.
  • Finishing Move: Brain Head Crusher: Brain leaps into the air and performs a flying kick charged with his toxins at his opponent...then lands in front of them, redirects the toxins into his head, and delivers a powerful headbutt at the opponent.
  • Foil: He's one to Kamen Rider Heart. While he transforms by simply turning the Advanced Igition on his modified Banno Driver, his sole Kamen Rider form shares the same aesthetics as Gold Drive, and his "Mr.Belt" is Crystal Peppler, a human scientist that looks suspiciously like Krim Steinbelt, Heart transforms with a Shift Car and Drive Driver, his forms are based off of Kamen Rider Drive's own forms, and he had his own "Mr. Belt" in the form of his fellow Roidmudes Brain and Medic. While Heart still fights hand-to-hand with his full strength restored, Brain possesses his own unique gear, including a Sunglasseslasher recolor and his handkerchiefs. Also, ultimately Heart transformed into a Kamen Rider while in the real world, while Brain only transformed while in a dream.
  • Irony: For the man who is extremely devoted to Heart, his Driver resembles the Driver of Banno/Gold Drive, the man Heart most despises, and also shares his appearance with both him and Proto-Drive, the Rider that foiled Heart's Global Freeze plan the first time around.
  • Poisonous Person: Turned Up to Eleven as a Kamen Rider, as he claims that he's now able to produce 999 types of toxins
  • Lethal Joke Item: His '''Poison Handkerchief" attack, which he throws his signature handkerchiefs, completely covered in poison, to kill Dark Kiva and Another Para-DX on contact.

    Chase/Mashin Chaser/Kamen Rider Chaser 

Chase/Mashin Chaser/Proto-Zero/Kamen Rider Chaser

Portrayed by: Taikou Katoono (live), Yasuhiko Imai (suit)
Drive's rival and enforcer for the Roidmudes. His mission is to defeat Drive and also assassinate Roidmudes that fail to follow their orders.

His true identity is the 000 Human-type Roidmude Proto-Zero, who was previously Kamen Rider Proto-Drive before being captured and brainwashed. He later regains his memories and becomes Kamen Rider Chaser.

Tropes that apply to him in general

  • The Atoner: For breaking Shinnosuke's arm, and his past action when he was turned into Mashin Chaser, Chase becomes a Kamen Rider again, donning the mantle of Kamen Rider Chaser.
  • Badass Baritone: A powerful warrior and he has a rather deep voice.
  • Badass Biker: Rides a motorbike called the Ride Chaser.
  • Bequeathed Power: Gives Go his Signal Bike before he dies, enabling him to become Chaser Mach and kill Banno once and for all.
  • Big Damn Heroes: After his turn to good, Chase uses his 'Pop out of nowhere' powers for good always arriving to save the day.
  • Blood from the Mouth: Chase coughs up blood in Kamen Rider Drive Saga: Kamen Rider Chaser when he stabs himself in the chest with the Rhino Super Viral Core to remove Angel's feather, because the feather gives him emotions at the cost of making him incompatible with Signal Chaser.
  • Brainwashed and Crazy: Brain reprogrammed him to be the Roidmudes' enforcer. And when that didn't completely take, Medic took a shot at it.
    • However even Medic notes that Chase's core is quite difficult to access and change, proven when even she could only slightly change his code. So there's a chance that his code will reject the modifications to it.
      • And indeed, he seems to briefly flash back to his true programming in #21, when Shinnosuke reminds him about Kiriko. Though it doesn't stick. As it turns out, this is due to Brain, as Chase completely reverts in #22. Sadly, Medic just re-brainwashes him and turns it up several notches until he was defeated by Drive Type Formula. After that, he's free of it and has joined Team Drive as Kamen Rider Chaser.
  • Bishōnen: The actor playing him is a model after all and even won an award from Junon, a Japanese women's magazine.
  • The Brute: An exceptional fighter who does most of the Executors' field work.
  • Cold Ham: Always looks and sounds rather stoic, even when he's engaging in the same sort of silliness as those around him. This also makes him...
  • The Comically Serious
  • Composite Character: Chase has Proto-Drive's memory and fighting skills, but his human form is copied from Koichi Kano.
  • Died in Your Arms Tonight: He took several fatal blows for Gou before falling into his arms, before giving him his drivers license and signal bike, the two things given to him by his human friends.
  • Discard and Draw: From Mashin Chaser's Hyper-Slowdowns and Break Gunner to Kamen Rider Chaser's Executioner's Axe
  • The Dulcinea Effect: He fixates on Kiriko for some reason that even he's not sure of. It's suggested that he remembers rescuing her during the Global Freeze, which only reinforces the trope.
  • Emotions vs. Stoicism: His rivalry with Drive can be interpreted as such, which Chase firmly as The Stoic. Played for Laughs when Chase asks Shinnosuke whether or not he likes Kiriko.
  • Evil Sounds Deep: Contrary to his Bishōnen looks, he has an incredibly deep, intimidating voice. Even the Break Gunner has a low, dark rabble.
  • The Faceless: We never get to see Proto-Drive's real identity. We might think that he looked like Chase's human form, but Chase copied his appearance from someone else.
    • Subverted. We see him transform into Proto-Drive in Drive Saga: Kamen Rider Chaser
  • Fate Worse than Death: If Heart had merely destroyed his body during his last mission as Proto-Drive, Chase simply would have reformed elsewhere over time. Instead, now knowing that he was in fact a Roidmude himself, Heart, Brain, and Freeze kept his physical form stable so they could (painfully) reprogram him to fight for their cause.
  • Foreshadowing: His fellow Roidmudes are infinitely more expressive and emotional than he is which is a fairly early clue that they weren't made by the same scientist.
  • Gone Horribly Right: Krim created him to be a relentless enforcer free of doubt and mercy. After his brainwashing, Chase spends almost half of the show antagonizing his maker without hesitation, operating as intended albeit towards the wrong target.
  • Heartbroken Badass: Downplayed thanks to his not really understanding love at first. He develops feelings for Kiriko, but realizes that she likes Shinnosuke (and the feeling is mutual). He doesn't angst about it, but sheds some Manly Tears and resolves to fight to make Kiriko happy, even if it's not with him.
  • Heel–Face Turn: From a brainwashed Roidmude hitman to a reformed Kamen Rider.
  • Hell-Bent for Leather: Purple leather pants and riding jacket, plus black leather boots.
  • He's Back: In #26 he decides to start over again as a Kamen Rider for Kiriko's sake.
  • Humans Are the Real Monsters: He firmly believes this, as shown in episode 5, using the weapon smuggling ring as an example. Strangely enough though, it seems like he can't bring himself to kill them. This has something to do with his prior life as Proto-Drive.
  • Hunter of His Own Kind: A non-lethal variant as he's tasked with "resetting" Roidmudes that cause too much trouble. However, as Proto-Drive, he expressed utter disgust at his rebellious brethren and would have exterminated them if the means had been available to him then.
  • Image Song: Spinning Wheel, which he shares with Shinnosuke and Gou.
  • Implacable Man: Chase is a very fitting name. He is incredibly dedicated to hunting down Drive — at times it seems like Shinnosuke can't drive twenty feet without Chase suddenly appearing.
  • Ironic Nickname: Despite being called "The Grim Reaper", he's doesn't actually kill Roidmudes, a point he brings up to Shinnosuke quite bitterly. Heck, he can't even bring himself to kill humans either.
  • It's Personal: He hates Drive for killing his fellow Roidmudes.
  • I Want My Beloved to Be Happy: Falls in love with Kiriko, but realizes she loves Shinnosuke and vice versa, so he merely chooses to do all he can to make her happy, even if it's not with him. This is also why he sacrificed himself to save Go.
  • Knight of Cerebus: While Chase was there from the first episode after He's revealed to be Proto-Drive and is re-brainwashed Chase becomes a far more dangerous opponent and there is a lot less comedy in the show even when he isn't on screen.
  • Laser-Guided Amnesia: For some reason, Chase can't bring himself to shoot Kiriko, and humans in general due to memories about her. This is probably why he always lets Shinnosuke transform into Drive. Aside from that, he doesn't even know what exactly what he is either.
    Chase: Kamen Rider... What is he? For that matter... What am I?
  • Mr. Fanservice: His tight purple leather, being played by an award winning Bishōnen, and his deep, sexy voice completely solidify Chase's position as this trope. The V-Cinema also tosses in a few shirtless scenes of him.
  • My Hero, Zero: Villainous example. Chase's true form is Roidmude 000/Proto-Zero, a Human-type Roidmude.
    • Was once a heroic example, however, as Kamen Rider Proto-Drive. ...and becomes a heroic example again by becoming Kamen Rider Chaser.
  • Noble Demon: He'll fight Drive only if he's unoccupied at the moment or attacking a fellow Roidmude. He also refuses to kill humans or otherwise put them in danger, though not even he understands why. As shown in #11, he lets Drive go rescue Kiriko upon hearing that many human lives were at stake.
    • When Kiriko finds him to get a sample of an evolved Roidmude to help Drive attack only the Roidmude part of the Sword Roidmude, he blasts off a part of his Mashin Chaser torso armor.
      • He's so noble that he defects back to the heroes' side after feeling horrible about hurting a human being; in this case, Shinnosuke.
  • OOC Is Serious Business: Krim, Shinnosuke, and Kiriko are understandably shocked when Chase shows up being genial courtesy of Angel, to the point where poor Go is the target of a triple Spit Take.
  • Perpetual Frowner: To the point that it is really jarring to see (an illusion of) Chase smiling in #16.
  • Professional Killer: Goes after all his bosses' targets, whether they be rogue, idiotic Roidmudes or their enemies like Drive. All the while showing no emotions whatsoever.
    • However, he doesn't actually "Kill" his targets, instead making them go back into being cores so they can start over from being unevolved again. Except For Drive, at least. This is why he hates Drive and calls him the TRUE Grim Reaper, because he kills his comrades.
    • He doesn't kill humans either; he claims this is due to him viewing them unworthy to be killed, but it's hinted he's lying and genuinely doesn't know why he's unable to do so. See Thou Shalt Not Kill.
    • Interestingly, Medic re-brainwashes him by changing his programming to protect humans into programming to protect Roidmudes. So he can't be the Grim Reaper anymore.
  • Purple Is Powerful: In both his forms, he wears plenty of purple, and can kick everyone's ass like there's no tomorrow.
  • Red Oni, Blue Oni: The calm, dutiful, and aloof blue (one of two) to Gou's reckless and flashy red.
  • Redemption Promotion: After his Heel–Face Turn, Chase becomes The Juggernaut for the heroes kicking ass and taking names without pause.
  • Reforged into a Minion: Formerly the Roidmudes' greatest enemy; now their dreaded enforcer.
  • The Rival: This magazine scan compares Drive and Chaser to Kamen Rider BLACK and Shadow Moon. Emphasized in #10, where he has a Showa-style monologue about how fighting Drive will help his memory process that echoes that to something Shadow Moon or another enemy of the classic Kamen Riders would say.
  • Sacrificial Lion: He dies in battle with Banno, loyal to the end to protecting his friends and all of humanity.
  • Significant Double Casting: Chase's live actor is also the voice of Proto-Drive.
  • Sixth Ranger: To the Roidmudes at first since he's a different type of Roidmude to begin with. In episode 17, Medic explains that she altered his programming so that Chase now protects Roidmudes instead of humans. After his reformation as a hero, Chaser becomes the series' resident Tertiary Rider, joining forces with the protagonists in their battle against his former brethren.
  • So Long, and Thanks for All the Gear: He's heavily upgraded by Brain and Medic over the first two cours of the show, and keeps his enhancements when he switches sides.
  • Stealth Hi/Bye: He is usually pulling the camera focus variety of stealth hi, but doesn't seem to be aware it. The most sudden one was when he somehow dropped on the Tridoron's hood out of nowhere.
  • Taking You with Me: Chase attempts to take Gold Drive down with him as his body explodes. It didn't work, much to Go's chagrin.
  • Thou Shalt Not Kill: In episode 14 he starts hearing Krim's voice in his head, saying the words "Protect the humans". It's later revealed he can't kill humans because it's part of his programming.
  • Teeth-Clenched Teamwork: With Go. My Sister Is Off-Limits! and some well-meaned animosity being at play, no one can really blame them. They usually avoid each other unless the need arises.
  • Token Heroic Orc: Chase is a Roidmude but has a heart of justice and is one of the few Kamen Riders who was never human in any way.
  • Tomato in the Mirror: Every time he fights Drive he feels a stirring within himself, eventually culminating in the reveal that he was the original Drive.
  • Took a Level in Badass: One aspect of Chase that makes him such a dangerous villain, and an even better hero, is that he never stops taking levels in badass.
  • Unexplained Recovery: Very unusually for the continuity-heavy Drive, the show never explains how Chase survived his defeat at Type Formula's hands despite his Core exploding on-screen.
  • Villains Act, Heroes React: An inverted-role example. Whenever Drive has a Roidmude on the ropes, you can be sure that Mashin Chaser will come and put a stop to it.
  • Villain Forgot to Level Grind: Balls to the wall averted. Chase continues to get upgrades of his own all throughout the show, readily keeping pace with Drive and blowing far past Mach.
  • Vocal Dissonance: With his bishonen looks, you would expect him having a rather high voice, instead his voice is rather deep.
  • What Is Love: His gradually increasing feelings for Kiriko spurred his Heel–Face Turn, and late in the series he begins to ask this question directly.
  • What Measure Is a Non-Human?: Besides Heart, Kiriko and Shinnosuke are the only ones who treat Chase like an actual person for most of the show. Even after he switches sides, Krim is largely ambivalent to his presence and actively discourages Chase from trying to become more human as he believes that doing so will compromise on his performance as a fighting machine.
  • When He Smiles: In episode 39 during a driving lesson. Giving his allies a thumbs up to wish him good luck for a test. Creepy, huh?
  • Wistful Amnesia: In episode 14 he exclaims that he remembers Kiriko somehow, and he also hears Krim's voice in his head.
    • As it turns out, Chase is still under the effects of this. His memories from before the Global Freeze are locked up within Proto-Drive's Shift Car, and he can't access them until it's repaired.
  • Worf Had the Flu: As Chaser, the only reason Go is able to beat him is because Chase doesn't want to hurt humans anymore.
  • You Have Outlived Your Usefulness: His job is to enforce this trope on other Roidmudes, making them start over so they might POSSIBLY be useful again one day.

Tropes exclusive to him as Mashin Chaser
Brake Up!
Tune Rhino! Super Break Up!
  • Boring, but Practical: His Break Gunner doesn't have the flashiest activation for when he transforms, but it can be used as both a projectile and melee weapon regardless of his current state. And while his Chaser Viral Cores don't afford him a wide variety of powers (Drive) or mods that can change the flow of battle (Mach), they do a tremendous job at amping up the range and destructiveness of his all ready considerable combat abilities.
    • This continues into his Super Form, while he isn't capable of accessing his Chaser Viral Cores while in this state, it gives him an improved close-ranged option in the Rhino Strizer added to the Break Gunner, while the boost to his Gun Mode and increased strength the form gives him lets him remain just as dangerous despite the further reduction of options.
  • Evil Knockoff: Apparently, Chaser's design is based on Proto-Drive. More precisely, he is Proto-Drive.
  • Golden Super Mode: His Super Mashin Chaser form, gained during Drive Saga: Kamen Rider Chaser after Angel gives him the Rhino Super Viral Core to compensate for the loss of his ability to transform into his Kamen Rider form. Like Gold Drive, this form is the "Mashin Chaser" equivalent to the Roidmude's Super Evolution State.
  • Finishing Move: Activates finishers called "Full Breaks".
    • Execution Spider: Consists of an energized slash with the Fang Spidey.
    • Execution Cobra: Chaser detaches the Tail Whipper off of him, with said weapon striking the foe multiple times hood first.
    • Execution Bat: The Wing Sniper attaches to Chaser's back, and Chaser comes in with a Diving Kick.
    • Super Blade: Chaser fires several golden blasts from the Break Gunner, and then finishes off his opponent with a stab from the Rhino Strizer.
  • Power Copying: He is able to use any of Drive's Shift Cars against him, as poor Max Flare found out...
    • This gets turned on him in episode 14, when Mach's Ride Macher combines with the Mach Chaser to form the Ride Crosser under Mach's control.
    • It works against him again in #16, when Drive deliberately has him use Deco Traveler; causing him to get distracted by the flashy kabuki stage that appeared.
  • Power Gives You Wings: Whenever he uses a Chaser Viral Core, the weapons will first emerge from his back in the form of purple devil wings and then morph into his weapon. The Chaser Bat is specifically meant to equip powered wings.
  • Punny Name: A play on the word "Machine", and the kanji used can mean "advanced demon".
  • Shinigami: Often introduces himself as one, which a fansub translates as The Grim Reaper. Most Roidmudes have taken that to the heart.
    • Interestingly, he says that Drive is more of a reaper than he is as Drive kills Roidmudes while Chase only "resets" them.
  • Stealth Pun: In Kamen Rider Drive Saga: Kamen Rider Chaser, he gets access to a new Viral Core called the Rhino Super. Given that Chaser is based on a virus, it could also be called a Rhinovirus.
  • Weapon of Choice: The Break Gunner is his transformation device, knuckle, and gun all in a single one-handed gadget. Combined with Viral Cores, it can give Chaser a special weapon that transforms into various modes depending on the Chaser Viral Core used:
    • Chaser Spider: Blade Below the Shoulder, with some Sword Beam added to the mix for the extra oomph.
    • Chaser Cobra: Whip It Good. Transforms from Chaser Spider by folding into itself to stimulate a hooded cobra and generating the whip part.
    • Chaser Bat: Energy Bow. Transforms from Chaser Cobra by retracting the whip part and the "hood" spreads apart to simulate spiked wings.
    • Triple Tune: All Your Powers Combined: By inserting the Chaser Spider, then Chaser Bat, and finally Chaser Cobra, he gains a hybrid weapon of the above three called the Dead Liberation.
    • Rhino Super: Bayonet Ya. Unlike the other Chaser Viral Cores, its generated from the Viral Core's "horn" automatically when he transforms into Super Mashin Chaser.

Tropes exclusive to him as Kamen Rider Chaser
Rider: Chaser!
  • An Axe to Grind: The Shingou Axe, which lets him pull of a Full Throttle attack called the Across Breaker with his Signal Bike.
  • Boring, but Practical: He has the ability to use Drive and Mach's wide selection of Shift Cars and Signal Bikes, but prefers to use his own. Signal Chaser allows him to transform and use his Finishing Move while Shift Speed Prototype simply boosts his attack power and speed for a brief period of time.
  • Fashionable Asymmetry: His helmet retains some of the chrome engine parts from his Mashin Chaser suit on the left side, but is smooth and purple on the right.
  • Finishing Move: Has his own set of "Full Throttle" finishers.
    • Across Breaker: Chaser inserts the Signal Chaser Signal Bike into the Shingo Axe where, after waiting for the weapon to charge, it gives out an energized slash that rends all in its path.
    • Chaser End: Chaser's Rider Kick, which he used to clash with Mach's Rider kick.
  • Good Costume Switch: The first time he transformed and cemented his Heel–Face Turn, his Mashin Chaser suit burst off him to reveal his Kamen Rider Chaser suit.
  • Lightning Bruiser: Oh my yes. Chaser is a juggernaut, punching harder than anything Drive has, kicking harder than any of the Dead Heat forms, jumps close to Type Formula's maximum jumping height (a solid 5 meter of distance in between them), and has a running speed that's minutely faster than the Dead Heat forms' base speed. Only Drive Type Tridoron has higher stats than Chaser.
  • Palette Swap: He's a paradoxically darker and shinier version of Kamen Rider Mach, but with a unique helmet and color scheme with a different placement for his Shift Tire and a pair of decorated shoulder guards.


009 Medic Roidmude

Portrayed by: Fumika Baba (live), Toshihiro Ogura (suit)
A female Roidmude who joins Heart and Brain in searching for the "Promised Number." Previously, she was in a "sleep" state, but Volt Roidmude created a device to gather enough amount of lighting to wake her up. Now, with her powers to heal and restore Roidmudes defeated by the heroes, she is a valuable asset to Heart and Brain.
  • Alas, Poor Villain: Friend and foe alike are shocked when she gets mindwiped and brainwashed by Banno. Even Brain mourns her loss, which confuses him since he hated her.
  • Back from the Dead: Unlike other Roidmudes defeated during Global Freeze, she needed to be resurrected through Heart's gambit.
  • The Bad Guys Win: Despite Drive stopping Volt's plan, Medic absorbed enough stolen electricity to be revived.
  • Ballet: Influenced from the human she copied, practically every movement from her is like a dance move. Unfortunately there's no Dance Battler or She-Fu in her first real fight, just a lot of Combat Tentacles.
  • Berserk Button: It only took Drive merely scratching her with the Handle Sword to get her to reveal her Roidmude form.
  • Bitch in Sheep's Clothing: To Heart, she's the sweetest thing ever. Everyone else, up and including other Roidmudes, she treats with disdain at best. Although this wasn't completely her fault.
  • Brainwashed and Crazy: Courtesy of Banno, right before what could have been a HeelFaceTurn. Everyone mourns her, shockingly. If not for Brain's Batman Gambit, she would have died in this fashion.
  • Can't Take Criticism: For all the insults she slings out, the one time Drive calls her out on her plans, her face quickly turns into a scowl.
    • 001 seems to be well aware of this aspect of her personality, and when she mockingly (but as always politely) suggests he's panicking because his identity has been discovered by the Riders he shuts her up with a bout of laughter.
  • Combat Medic: Her main duty is the repairing and upgrading of other Roidmudes, but she's hardly a slouch when it comes to fighting - even approaching Dance Battler territory in her second fight (with the dance being ballet, of course).
  • Darker and Edgier: After her aspirations for genocide are revealed, all of her perkiness disappears.
  • Dark Action Girl: Yes, Medic is an evil bitch but that doesn't mean she can't fight.
  • Dark Chick: The sole female member of the Roidmude Executors and their healer.
  • Dissonant Serenity: She makes her debut to the heroes by dancing in the flames from the explosion of a fellow Roidmude, right in front of two guys who would eagerly destroy her there and now. All the while mocking Mr Belt for his current state with a calm smile on her face.
  • Dragon-in-Chief: Despite the three Executors being officially equal in rank (and unofficially Heart is their leader), Medic became the main enemy up until Freeze was introduced - Heart didn't know the details of what she was up to, and Brain did know but was powerless to stop her.
  • Dragon with an Agenda: She realizes just how futile resetting Roidmudes can be, so her plan is to cull the Roidmudes to only a select few, counting herself and Heart.
  • Dying as Yourself: Reverts to her original pure form before healing Shinnosuke and dying thanks to Sigma.
  • Elegant Gothic Lolita: Her human form.
  • Ethereal White Dress:
    • She first appeared this way following taking her human's identity, until she was corrupted by the negative emotions of the Roidmudes she healed. Heart referred to her as a goddess when she first appeared, in comparison to the devil in the present.
    • She takes this appearance on one last time while healing a grievously wounded Shinnosuke.
  • Evil Wears Black: Played with. Her clothing originally starts off as white, but as she continued to use her healing powers, she absorbed negative energy from other Roidmudes and became corrupted herself, signified by her white clothes becoming black.
  • Faux Affably Evil: She's polite and elegant...and has no true concern for anyone but herself and Heart. She's also prone to mocking and insulting people using the most polite and gentle words possible, even 001, the first Roidmude.
  • Florence Nightingale Effect: The relationship between Medic and Heart has shades of this. It's justified when it's revealed that most Roidmudes except Heart are programmed with negative emotions, and Medic absorbs the emotions of Roidmudes she heals, so Heart is literally the only person who she can enjoy healing, because she absorbs his positivity and joy.
  • Healing Hands: She can absorb the Core of a Roidmude, presumably before destruction, to later restore back to it's evolved form. She can also heal Roidmudes regularly, as shown when she's tending to Heart's wounds. Late in the series it's revealed that she can heal humans and animals too.
  • Heel–Face Turn: Has this moment in helping Shinnosuke find out the true identity of the culprit attacking the human she copied, prior to being abducted by Banno, then Brainwashed and Crazy temporarily. After Brain's Heroic Sacrifice, she joins forces with Heart and Team Drive to fight a common enemy in Banno.
  • Heroic Sacrifice: Medic uses the last of her power to heal a seriously wounded Shinnosuke after both he and Heart fail to destroy Sigma Circular.
  • High-Class Gloves: They just add to her elegant image.
  • Irony: Medic has the ability to heal other Roidmudes and bring them back from the brink of death, but she's one who decides to permanently kill off the ones she doesn't approve of (something Brain or Heart have never considered doing).
    • She's also fond of brainwashing others to get what she wants, and her ultimate fate is to become Banno's puppet.
  • Jerkass: If your name isn't Heart, she'll happily insult you just because she can. She cannot, however, take being insulted in return.
    • Revealed in #42 that she wasn't like this to the Roidmudes when she wore white. When she healed all the Roidmudes defeated by Proto-Drive, she ended up absorbing their negative emotions.
  • Karma Houdini: Shinnosuke stops Gou from killing her because she cares for Heart, despite said love causing her to demean and bully others, as well as committing genocide on her own kind for what she thinks is for Heart's sake. To make things worse, Heart forgives her, so she gets off scot-free for her genocidal plans.
    • However, it was later revealed that her sociopathic tendencies were side effects coming from absorbing those whom she healed; Banno took advantage of this and unlocked her Ultimate Evolution, becoming his puppet in the process.
  • Klingon Promotion: Non-lethal example. Because she altered Chase's personality so that his directive is to protect Roidmudes instead of humans, the role of Reaper is empty. Convenient for her to take and execute her plans.
  • Knight of Cerebus: While originally the Perky Female Minion, after her plans for genocide are revealed she solidifies the show's Cerebus Syndrome.
  • Lack of Empathy: She clearly only cares about two people: Herself, and Heart. Not understanding why Heart is depressed over Chase's "death" is just one of the many examples of this. She could be as a Deconstruction of this trope, as her inability to care about anyone who's not Heart ultimately ends up causing her to perform actions that leave him absolutely livid with her. Additionally, she originally was filled with empathy for others, but taking all their negative emotions into her corrupted her into what she is today.
  • Lust: Initially thought to be the unique emotion that allows Medic to evolve. It turns out to be Devotion.
  • The Medic: How could you have ever guess?
  • Mad Doctor: While she starts off as the Roidmudes' healer, Medic later switches to modifying and mutating Roidmudes to make their ranks stronger.
  • Madness Mantra: After being mindwiped by Banno, all she can say is "I did it all for Mr. Heart." Over and over and over and over again, dully and without any emotion. Poor girl.
  • Manipulative Bitch: Correct on both accounts. Upon finding out that Chase was freed from her brainwashing by Brain, she ups it to such a degree that Chase will kill ANYONE she tells him to. She then uses him to get the truth out of Brain...and for good measure burns his handkerchief just to be petty. Oh and of course, she conveniently lied about 072's ultimate fate, blaming Drive for his demise.
  • A Nazi by Any Other Name: Medic has aspirations to perform an ethnic cleansing on the Roidmudes removing 'flawed' members from their ranks and her Reaper Legion has disturbing undertones to the SS.
  • Not So Stoic: She's greatly alarmed when Mach manages to set Brain on fire and calls for immediate treatment of his injuries.
    • She also freaks out a bit when Heart catches her in the act of using fellow Roidmudes as experiments with no regard for their lives.
  • Official Couple: With Heart, and Brain is incredibly envious of her for it.
  • Out-of-Character Moment: In #15 she was actually worried when Brain was hurt when later episodes make it clear she doesn't care about his life.
    • Could be justified due to the fact that Heart values Brain as a close confidante and seeing him hurt would deeply worry Heart which is something Medic wants to avoid.
    • Finally justified when it's revealed that Medic is tainted by the negative emotions of the Roidmudes she healed. Her concern for Brain back then may have been one of the last vestiges of her kindness briefly reappearing.
  • Panty Shot: A quick one towards the end of #42.
  • Perky Female Minion: Less energetic than usual, but she's certainly (sometimes disturbingly) upbeat.
  • Pet the Dog: This is how she got her human form as well as her powers in the first place; after getting injured from a failed Global Freeze invasion, 009 met a women who was in a brink of death and copied her, along with her strong emotion of love. After healing her and bringing her out to safety, she also healed the dog the woman had the strong love towards.
  • The Power of Love: In Episode 31, 001 states that the unique emotion that allowed Medic to evolve was Lust. It turns out to be pure, unconditional love, and that it was merely corrupted to Lust when she absorbed the negative emotions of the Roidmudes she healed.
  • Proper Tights with a Skirt: Her human form looks like a well-dressed woman.
  • Reforged into a Minion: Courtesy of Banno.
  • The Smurfette Principle: The only female Roidmude seen, if you don't count Iron's Gender Bender scene or 096 taking on a feminine voice. Angel is a female Roidmude, though Medic is still the only female Roidmude to be a main antagonist throughout the series, as Angel is the Big Bad exclusively for the Kamen Rider Drive Saga: Kamen Rider Chaser special.
  • The Sociopath: Being a Roidmude this is kind of a given, but despite her warm smile and poetic movements she's willing to do anything and everything to advance her goals and keep Heart happy. With the exception of Heart, none of her fellow Roidmudes mean anything to her. She eventually grows out of it by #42.
  • Something About a Rose: When she teleports or changes form, it's with a visual effect that looks like rose bushes.
  • Sympathy for the Devil: Shinnosuke comes to pity her, seeing how she just wants to love someone but is unable to without issues.
  • Token Evil Teammate: Even though the Roidmudes are far from being saints, as loyal as Medic is towards Heart, she isn't above disposing of her own kind.
  • Undying Loyalty: Appears to display this towards Heart. Brain is not happy.
  • Used to Be a Sweet Kid: Started out as a genial Roidmude who heals her fellow Roidmudes, having then corrupted by the negative emotions she absorbed, leading to her being heartless to others that aren't Heart.
  • We Have Reserves: Considers all Roidmudes except herself and Heart to be completely disposable.
  • When She Smiles: She has quite a wide and warm smile when she's revived. She also has a tendency to smile while politely and gently insulting others, but 001 wiped the smile from her face instantly when she tried to mock him.
  • Yandere: A complete one for Heart. She will do anything to keep him happy.


001 Freeze Roidmude

Portrayed by: Masami Horiuchi (live), Masaru Obayashi (suit)
The first Roidmude, who prefers to stay in the background while others handle the day-to-day duties. He has infiltrated human government as Secretary of Defense Soichi Makage. Once his presence becomes known, this have gotten much more serious.
  • Affably Evil: First thing he says upon meeting Shinnosuke is telling him to keep up the good work. He also speaks highly of Kamen Rider Drive.
    • When Shinnosuke directly confronts him and he reveals how Shinnosuke's father Eisuke opposed him, he sounds almost respectful, especially when he recounts how Eisuke's unyielding will actually forced him to falter. Both these cases might have something to do with the fact that he gets his powers from being humiliated, which talking highly of your enemies can certainly do.
  • An Ice Person: Aside from his memory-freezing powers he also has ice powers of the regular garden variety.
  • Authority Equals Asskicking: The real man in charge of the Roidmudes and their real main asskicker.
  • Badass in a Nice Suit: His human form is often dressed in a very stylish suit and hat, with an overcoat wrapped around his shoulders.
  • Batman Gambit: He relies on pushing the berserk buttons for both Shinnosuke and Gou to either take them out of the battle or persuade them to their side.
  • Big Bad: One of the most powerful Roidmudes seen and acts as The Man Behind the Man to the other leaders.
    • The Dragon: He prefers to act as one to Heart, noting to Medic that Heart has all the characteristics of a great king.
    • Dragon-in-Chief: Even then, whenever Freeze shows up, nobody's under any delusions about who's really in charge.
    • Subverted when Drive Type Tridoron makes short work of him, reducing him to just an Arc Villain and Disc-One Final Boss.
  • Came Back Strong: Freeze's first defeat by Drive Type Formula Mantarn helped spark his Super Evolution.
  • The Chessmaster: The man's been playing the game for over twelve years, moving many pieces to his desired outcome.
  • Death by Irony: 001 developed the Hybrid Evolutions, a combination between a Roidmude and a human host. He is defeated by Kamen Rider Drive Type Tridoron, a combination between Shinnosuke (a human) and Mr. Belt (a cybernetic being not unlike a Roidmude).
  • The Dreaded: Even more so then Heart. Krim is so afraid of Freeze that he causes a lot of internal conflict with Shinnosuke and the team in order to avoid facing him.
  • Evil Sounds Deep: He has a low, intimidating, voice.
  • Expy: Freeze blends traits from several of Riku Sanjo's prior villains, particularly Gamou and Ryubee. Like the Big Bads of those shows, he's an older gentleman in a position of authority that makes him inassailable and has powers responsible for maintaining The Masquerade, but his role in the story and skill at enhancing Roidmudes are derived more from the Arc Villain from Double. Blending these elements produces the twist that when Freeze dies, so does his power, and Drive fully makes the transition to The Unmasqued World.
  • Failure Gambit: Uses the humiliation felt from losing to his archenemy's son in order to obtain his Ultimate Evolution.
  • Famous Last Words: Played for more drama as he hints that he's not the one who killed Shinnoske's father, and the real killer is on the loose. It even lingers onto the next episode, as Shinnoske is troubled by it.
    Freeze: Your fool's victory in finding vengeance for your father is truly amusing. I hope you choke on the dark truth once it is revealed!
  • First Of Its Kind: The very first Roidmude. Or at least one of the first.
  • Fusion Dance: Invented Neo Viral Cores, which can fuse Roidmudes and humans together.
  • Hero Killer: Kills both Shinnosuke and Mr Belt with a single attack in Episode 32.
  • Knight of Cerebus: Yes, Medic and Chase managed to darken the series with the reveal of hidden motives and brainwashing respectively, but 001 managed to put the show's plot into motion in his debut while the two had to wait several episodes to become the knight. In the handful of episodes since his appearance, he's revealed he's been pulling the strings of the Japanese government, has successfully lured Gou to serve him and also admitted he's the one who killed Shinnosuke's father.
  • The Man Behind the Man: He prefers to work from behind the scenes. Medic observes that this makes him very reliable, but also very ominous. Considering that he's almost single-handedly kept everyone in the dark about the Roidmudes thanks to his memory alteration powers, she's got a very good point.
  • Mark of the Supernatural: People who are memory wiped by Freeze are left with a snowflake-shaped scar on the right side of their necks, just below the ear.
  • Memory-Wiping Crew: This is his primary power: to alter or freeze people memories, with coupled with his high position in the government, allowed him to maintain The Masquerade for so long. The drawback is that it will wear off after some years if not maintained, and some people are able to flatout resist it.
  • Mole in Charge: He's one of the Roidmude leaders while also being Japan's Secretary of Defense.
  • Power Of Hate: Or at least Humiliation, his unique emotion that triggered his evolution.
  • Reptiles Are Abhorrent: Unlike other Advanced Roidmudes, he still uses his original Cobra-Type form sometimes.
  • Sinister Schnoz: His Advanced Roidmude form has a big pointy nose.
  • They Look Just Like Everyone Else!: The rest of the Executors human forms dress in flamboyant clothing that wouldn't look out of place in a shonen manga on top of their outlandish personalities. In contrast, Freeze dresses and acts completely normal. As a Roidmude who prefers to stay in the background, this fits perfectly with his character.
  • This Cannot Be!: Has this reaction when Drive returns to life and his new Type Tridoron completely overpowers Freeze's Ultimate Evolution. To be fair, it's kind of hard to predict someone coming back from the dead.
  • Unwitting Instigator of Doom: As stated in #33's recap, everything that happened with Type Tridoron and Gou's newly attained tablet is because of him... and it's because of him that said tablet accelerates the extinction of the Roidmudes and nearly took over the world.
  • Villainous Friendship: Has this with at least Heart and Brain, and a lesser extent to Medic and other Roidmudes. Brain's request for his help is partially responsible for why he's gotten involved in the conflict, and he not only urges Heart to seek out a path to Super Evolution, he freely admits Heart makes a far better ruler than he himself.
  • Xanatos Gambit: Just about everything the heroes do seems to just play into his hands. For example, he tasks the Open Roidmude with eliminating witnesses from a bank robbery from 12 years ago where he was involved. It seems as though it is a desperate attempt to cover his tracks, but it also gives Brain ample time to recruit Gou to their side. He later reveals that even the discovery of his identity by Drive and Chase is simply another part of his plan, and he takes the precaution of having two of Medic's Reaper Unit with him to keep Chase busy until Mach arrives to engage him. This ensures his own confrontation with Drive will go uninterrupted. It all culminates in his Ultimate Evolution.


004 Spider-type Roidmude

Portrayed by: Chris Peppler (live), Eitoku (suit)

An enigmatic Executive who, sometime after the Global Freeze, went MIA and was out of contact with Heart. He had secretly been reprogrammed by Banno to serve as the agent of his revival, and to that end he copied Krim Steinbelt at the moment of the latter's death in order to obtain all of his knowledge. His attire in his human guise is nearly identical to that of "Future Krim".

  • Action Bomb: His final move.
  • Combat and Support: As he is a Low-Class combatman, he is the support to Gold Drive's combat in #43, where he uses the stolen Door Gun to weaken Kamen Rider Drive.
  • The Dragon: To Banno/Gold Drive.
  • Evil Genius: In addition to serving Banno, 004 copied Krim's intelligence and ingenious brain. He uses this to help Banno create some evil inventions.
  • Evil Is Hammy: Compare him to regular Krim.
  • Evil Knockoff: Just like most of Banno's other works of self-proclaimed scientific genius, 004 is a ripoff of something of Krim's genius. In this case, 004 is a ripoff of Krim himself.
  • Evil Wears Black: In his human form.
  • Famous Last Words: "Goodbye!" As he blows up right in the heroes' faces.
  • Four Is Death: Indicated by its number, helping the villain of the series and the way he died within the series.
  • Gadgeteer Genius: 004 was made to become this by copying Krim's data, obtaining all of his intelligence and this trope in the process. As a Gadgeteer Genius, 004 assists Banno in reverse engineering the Drive Driver and creating the Sigma Circular.
  • Gratuitous English: This trope was copied from Krim in addition to being a Gadgeteer Genius.
  • Incoming Ham: "Yesss..."
  • Irony: The Promised Number is 4, as in four Roidmudes who reached Ultimate Evolution, but even so, 004 is not among the numbers. However, it is justified; as 004 already has a completely different role, he has no need to keep up with other Roidmudes to evolve all the way.
  • Large Ham: Like with "Future Krim", Chris Peppler goes buck wild with his performance while playing 004.
  • Made of Iron: Survived Kamen Rider Drive's Finishing Move when he was in Tridoron Form and using Attack 1, 2, 3.
  • Puppet King: In the Bad Future, he pretends to lead a Roidmude army in his Steinbelt disguise while Banno (who's actually in charge) wrecks havoc as Gold Drive thereby posthumously tarnishing the reputations of both Krim and Shinnosuke in the eyes of what is left of humanity.
  • The Quiet One: Did not speak a single word as he grabbed the Drive Driver from Shinnoske and and helped Banno build a copy from it. Once he reveals his human disguise, however...
  • Satellite Character: His role is centered around Banno's plan. Justified, as Banno created him to be his personal servant.
  • Self-Destruct Mechanism: Self-destructs to try and kill the Riders and Roidmude higher ups.
  • Spiders Are Scary: And oh boy is he. He never evolved, and is secretly colluding with Banno.
  • Walking Spoiler: Much like his creator, you can't discuss him without bringing up spoilers.

     Advanced Roidmudes 

029 Iron Roidmude

Portrayed by: Nobuo Masuda (male form) and Iyo Sawai (female form) (live), Kazuya Okada (suit)

The first Roidmude that Shinnosuke faces. Starting as a Cobra-type Roidmude, he was apparently killing people together with 042 (Spider-type) and 088 (Bat-type), almost succeeding and leaving their bodies with red skin. Kamen Rider Drive stopped the trio's next attack, but 029 survived his Finishing Move and was given another chance by Heart thanks to another Cobra Viral Core. Eventually, Shinnosuke figured out that 029 had been kidnapping people with "perfect" physical traits in order to copy them and get more powerful. The apparent victims mentioned earlier only suffered a side effect when 029 rejected their physical bodies.

  • All There in the Manual: He is never called the Iron Roidmude on-screen.
  • Amusement Park of Doom: His hideout, where he keeps all the kidnapped people whose traits he copied.
  • Appropriated Appellation: He is the one that calls Shinnosuke a Kamen Rider.
  • Always Murder: The police had this mindset when they first investigated the case relating 029, thinking that the people in comas were attempted killings. Shinnosuke later realized that they were doing it wrong.
  • Bad Boss: He had two sets of two Roidmude Mooks. He got both sets killed.
    • He also kicked aside one Roidmude after the first two Mooks got floored by a Turbo Smash.
  • Gender Bender: Showcases the Roidmude's power of transformation this way.
  • Killed Off for Real: He is finally defeated by Drive's Type Speed Hunter's Full Throttle, JustiSmash.
  • The Perfectionist: He will only kidnap "perfect" people. If a victim will happen to have even the slightest cold, 029 will deem him a waste of time and put him in a coma.
  • Power Fist: Upon evolving, several of his new powers exhibit through his hands.
  • Purple Is Powerful: Played with. Upon evolving into Iron, his new body is mainly purple and he becomes much stronger... though not enough to survive a direct confrontation with Drive. note 
  • Red Herring: A civilian was thought to be behind the attacks when he was, in reality, one of the people kidnapped from their ideal physical traits.
  • Serial Killer: What the team initially thought they were dealing with, when the found victims were left in a coma and their skins red.
  • Terrible Trio: Before evolving, 029 was first seen together with 042 and 088. After evolving, he had 071 and 093.

010 Paint Roidmude

Portrayed by: Lou Oshiba (live), Daisuke Satou (suit)

A Roidmude that impersonated an artist in order to capture young females in his paintings. He is especially interested in Kiriko, which started when he was a Spider Roidmude. 084 (Spider-type) was his apprentice with similar powers. After 084 was busted in the team's investigation of kidnapped women, the Paint Roidmude tried to escape with the help of Chase but got one-upped by Kamen Rider Drive and Kiriko.

  • And I Must Scream: The fate of all the women he captured - being trapped in paintings.
  • Art Attacker: Paint can use his powers to turn and reform objects and people into data with his paint.
  • Fashionable Asymmetry: His Roidmude form, though he would probably call it 'avant-garde".
  • Hoist by His Own Petard: He was about to leave the area and get away... until his obsession with Kiriko got the better of him, resulting in his death.
  • Killed Off for Real: Destroyed by Drive's Dream Vegas Drift Slash via the Handle Sword.
  • Loves the Sound of Screaming: States it is Kiriko's terror that spawned his fascination with her and relishes her trauma induced fear of him, wanting to immortalize it.
  • Mad Artist: An obsessed with Avant-garde artist that traps his models in paintings, as well as a Roidmude, too.
  • Moral Myopia: Calls Drive a thief and is pissed off at him for stealing his paintings...that are actually the women he kidnapped.
  • Nice Hat: As Paint Roidmude, he has a beret.
  • Smug Snake: Acts this way during the interrogation in episode 4, all but stating that the kidnapped girls are at his mercy. Shinnosuke quickly drops him down a peg or two.
  • Symbolic Blood: The spot on his true form's coat, which taking his motif into account, may be interpreted as just a paint stain.
  • Villainous Breakdown: Begins having one when he realizes his paintings were stolen behind his back.
  • Weaksauce Weakness: The paintings with kidnapped women require constant supply of energy to keep them from escaping... which can be done by simply unplugging them.
  • Wicked Cultured: He truly sees himself as an extraordinary artist.

023 Crush Roidmude

Portrayed by: HIROnote  (live), Kazuya Okada (suit)

A Roidmude with 074 (Cobra-type) and 060 (Spider-type) as his underlings. He is responsible for several attacks on armored vehicles belonging to food companies. As it turns out, at first it was just a random stunt to get some food. But he and his troupe happened to come by a truck belonging to the Font El company, which was smuggling explosives in it's deliveries. Upon eating and getting a major power-up from eating them, he started attacking any similar truck in hopes of getting his hands on more explosives.

  • Addiction-Powered: He is clearly addicted to the taste of those smuggled explosives, which give him a sudden power-up.
  • Armed Blag: His main modus operandi.
  • Berserk Mode: Whenever he gets his fill of explosives.
  • Big Eater: When we first see him, he apparently finished several plates worth of food. He is also shown to constantly carry a huge jar of sweets. Though by far his favorite food are explosives.
  • Crazy Consumption: He will eat anything as long as it seems edible, up and including liquid explosives.
  • Drop the Hammer: Played with, as he doesn't wield one - rather, his forearms are shaped and used as hammers.
  • Fat Bastard: In human form.
  • Killed Off for Real: Gets cut down by Drive's Drift Rotation as Type Wild.
  • Made of Iron: Literally.
  • Shoulders of Doom: Just look at him, those things are huge.
  • Spell My Name with an "S": Due to how Japanese katakana works, his name can be read as either "Crush" or "Crash". Seeing as he is a hammer-themed Roidmude that specializes in attacking trucks, this may be intentional.
  • Power Glows: Every time he eats explosives, he will start glowing red.
  • One-Winged Angel: 074 consumed a few more Cobra Viral Cores to transform into a gigantic cobra and help Crush Roidmude fight Drive and his Trideron.
  • Terrible Trio: He has loyal lackeys in form of 074 (Cobra-type) and 060 (Spider-type). What's interesting is that these three actors compose a comedy trio called the Yasuda Dai Circus and that this series is not their first appearance as a Terrible Trio in a tokusatsu show.
  • Vocal Dissonance: One of his lackey Roidmudes, 074, as lampshaded by Drive. This actually the stage voice of Kuro-chan note , another member of the Yasuda Dai Circus.

033 Scooper Roidmude

Portrayed by: Hiroshi Naka (live), Satoshi Fujita (suit)
A Roidmude that evolved shortly after the death of Crush, by absorbing Shunsuke Kusaka's passion for making scoops. After that he made several buildings collapse, so Kusaka can photograph them and give him even more power. He appears to be helping making him successful, but that's because his evolution is incomplete and will once in a while revert back to a Bat-type Roidmude. Once his evolution is complete, however, he turned against Kusada, only to be taken down by Kamen Rider Drive.

024 Volt Roidmude / Volt Ghost

Portrayed by: Isamu Ago (live), Satoshi Fujita (suit)
Volt Roidmude
Volt Ghost

An arsonist of a Roidmude, causing electrical fires until the Shift Fire Braver stopped his latest one. When he and his lackeys investigated, they ran afoul with Drive. But even death doesn't stop this Roidmude nor his plan, as he was able to copy some of his code into the machine he was using to gather electricity. He then "returned" to life, albeit only a shadow of his former shelf - a literal ghost. Volt Ghost aimed to fulfill plan of creating a city-wide total blackout, seemingly aiming to cause chaos on Christmas Eve. But his true goal was to absorb the power from the city for Heart's own ends. Even when he is put down for good and Christmas saved, he still succeeded in feeding enough energy to revive the third Roidmude Executive - Medic.

017 Gunman Roidmude

Portrayed by: Bernard Ackah (live), Kazuya Okada (suit)

First operating in USA, Gunman and his "little brother" 018 came to Japan when their ran afoul of Kamen Rider Mach. There they then started to sell Slowdown inducing armbands to low-level criminals. Their motive was to evolve 018, who gained more power by absorbing ill-gotten money, with Gunman serving as his bodyguard. The Roidmude brothers met their end after the Riders uncovered their plans and subsequently got send to kingdom come by Mach.

  • Americans Are Cowboys: Copies an American mafia bodyguard, uses a revolver, wears a hat resembling the wide-brimmed ones cowboys wear, and has a cloak, bandolier, and Badass Longcoat evocative of drifters in late-1800's America.
  • Arms Dealer: Gunman has been selling wristbands that can cause Slowdowns to criminals. Devices created by Gunman's little brother 018's body.
  • Badass Cape: It goes nicely with his Gunman motive.
  • Black Dude Dies First: Inverted. He is the first Roidmude after Episode 1 not to get killed by a Rider's finisher.
    • Also averted later; when Mach defeats Gunman and 018, both of them bite it at the same time.
  • Charged Attack: He can charge up his shots.
  • Deader Than Dead: After getting his body destroyed by Kamen Rider Mach the second time, the Rider shoots his soul down while trying to get away as an extra measure.
  • The Gunslinger: Well, what you were expecting with that name, a swordsman?
  • I Call It "Vera": His gun, the Emperor 17.
  • Nice Hat: When you're based on a Wild West-stylized gunslinger, this is a must.
  • Nice Job Fixing It, Villain!: The Slowdown made it too slow for Genpachirou to fall to his death. He even landed on his two feet in the process.
  • Scary Black Man: The human identity Gunman took.
  • Sibling Team: Turns out his and 018's human forms were copied from a pair of brothers. As the result, he considers 018 to be his little brother.

030 Voice Roidmude

Portrayed by Hiroshi Matsunaga (live), Daisuke Satou (suit)

A Roidmude that masquerades as Shu Amagi, the owner of a popular dating service. Using his powers he was able to brainwash women into seeing him as their ideal man, leaving them comatose after they give him all their money. After being confronted by Drive and Mach, he turns out to have another identity: Kisaburo Sasamoto, Rinna's old boyfriend. It turns out the real Sasamoto is still alive, and was working with the Roidmude For Science!. Voice is ultimately destroyed, and Sasamoto is put behind bars.

  • Arm Cannon: His right arm, with he uses as a sound blaster.
  • Compelling Voice: His main power, which he uses to manipulate women to giving him all their saving and then puts them in a coma.
    • His compulsion over the women is so strong, it allows him to make his enslaved victims suicide bombers.
  • Kill and Replace: Killed the original Shu Amagi and took his appearance.
  • Killed Off for Real: Destroyed by Kamen Rider Deadheat Mach's Heat Kick Macher.
  • Make Me Wanna Shout: Unsurprisingly, in combat he uses sound waves.
  • Slime Ball: Weak, smug, and spends his time conning women.
  • Wrong Genre Savvy: Shinnosuke and Kiriko ask him to be invited for the secret event at his dating service in order to catch him red-handed or to ascertain his innocence. While Voice was being Smug Snake about it up to this point, we then have this glorious exchange:
    Voice/Shu Amagi: I think I saw a Cop Drama like this, once... The out of touch detective persistently dogging a celebrity suspect...
    Shinnosuke: Yeah, I loved that show. If I'm not mistaken, in the end the detective always wins, right?

065 Judge Roidmude

Portrayed by Seiroku Nakazawa (live), Daisuke Satou (suit)

Five years ago, a vigilante known as Judge ran a revenge-by-proxy website and took requests to assault victims. The vigilante supposedly committed suicide before he was caught, but Lt. Ohta and his mentor Shingo Tachibana believed that Judge merely faked his death by throwing his scapegoat off a bridge. Their beliefs were apparently vindicated when this Roidmude appeared, claiming to be Judge. Not only did this Roidmude resume Judge's actions, he is also able to go after large groups. Ohta vows to track down the Roidmude and end the case of the Judge once and for all. As it turns out, the Judge Roidmude has taken the identity of Shingo Tachibana. It was merely impersonating the vigilante Judge in order to lure the real one out. The vigilante Judge is eventually exposed, and the Roidmude is destroyed by Drive.

Portrayed by Naoki Takeshi (live), Jiro Uchikawa (suit)
Shoot Roidmude (Pre-upgrades)
A Roidmude responsible for several bombing attacks, each of with were announced to the police beforehand. He has the power to fire incredibly fast missiles and explosive darts. When he tried to use his missiles to bomb four places simultaneously, Drive foiled his plot and destroyed his body, but failed to actually kill Shoot and not before Shoot knocks Kamen Rider Mach out of commission with the heavy damaging of his Driver. Thanks to Brain, he gets a new body with the additional perk of adding poison to Shoot's weapons. He then proceeds to stalk and trying to kill his human accomplice Mogi, as the old bomb threats are now boring to him. He faces off again against Mach, being able to defeat him again, thanks to the toxin. Their next confrontation didn't turn out well for Shoot, though - while he managed to poison him again, Go used Deadheat's Explosive Overclocking to burn the poison out of his system, and managed to stay in control. He was then destroyed by the combined finishers of Mach Deadheat and Drive Type Formula.
  • Extra Eyes: Shoot has five eyes.
  • Flechette Storm: Shoot can... well, shoot darts too fast for the naked eye.
  • Killed Off for Real: Got send to kingdom come courtesy of the combined might of Type Formula's Trailer Impact & Deadheat Mach's Heat Kick Macher.
  • Mad Bomber: His method of terrorizing the city.
  • Not Quite Dead: Got defeated by Drive's Trailer Impact, but his Core survived the encounter and was soon picked up by Brain.
  • Poisonous Person: Thanks to Brain's upgrades following Shoot's first defeat, his Blast Darts now have a toxic punch to them.
  • Real Men Wear Pink: Has several pink accents on him, but he's still a remorseless serial bomber.
    • When Brain helps him back onto his feet, Shoot loses the pink coloring on his warheads and gains green accents in response to his upgrades.
  • Smug Snake: Very much enjoys talking Go down.

007 Sword Roidmude

Portrayed by Takashi Ohara (voice), Masaru Oubayashi (suit), Mitsuyoshi Tani (human host)
A Bat-type Roidmude who evolved by bonding into an evil heart of a criminal through the usage of a Neo Viral Core. The criminal in question was Hajime Taga, previously arrested by Shinnoske's former partner Akira. 007 intercepted one of his police transportation and offered him Neo Viral Core, allowing the two to fuse into Sword Roidmude. This allows Hajime to go after the hospitalized Akira in revenge, but Kamen Rider Drive stopped and defeated him, putting him back in jail. 007's Core, however, managed to survive thanks to the intervention of Roidmude 001, the creator of the Neo Viral Cores. When 007 hunted down Taga after gaining a new body and refuses with him to become Sword once again, he incapacitates Deadheat Mach, with Drive out of commission from an earlier bout with Mashin Chaser resulting in his left arm broken, and nearly kills Kiriko, only for Chase to arrive, and battles Sword, forcibly undos Sword's fusion, and destroys 007.

  • Axe-Crazy: Neither side of the fusion is psychologically stable.
  • Blade Below the Shoulder: His main weapons, well fitting someone called Sword.
  • Curb-Stomp Battle: He is on the receiving end of this twice; once by Drive outside the hospital, and the second with Kamen Rider Chaser, with both times resulting in Sword becoming de-fused.
  • Demoted to Extra: 007 was among the 9 Roidmudes who planned led the Global Freeze. In his debut, he followed 001 instead and ends up becoming a fodder.
  • Fighter, Mage, Thief: The first of the initial three Hybrid Evolutions, he fulfills the Fighter role.
  • Fusion Dance: Via the Neo Viral Core, 007 attained his evolved form through bonding with Hajime.
  • Impaled with Extreme Prejudice: Tries to pull this on Kiriko, but Chase averts this by slamming the Ride Chaser into Sword to send the fused Roidmude flying.
  • In Love with Your Carnage: He seeks out, saves and then fuses with Taga because of his murderous nature.
  • Killed Off for Real: Is rended asunder by Kamen Rider Chaser's Across Breaker with the Shingou Axe.
  • Not Quite Dead: Survives his bout with Drive thanks to Roidmude 001. Averted one episode later.
  • Red and Black and Evil All Over: A good amount of red, a fair dose of black and very much evil.
  • Red Eyes, Take Warning: Just before the fusion, 007's eyes glowed a sinister red.
  • Sword Beam: Can use his blades in such manner.
  • The Symbiote: Thanks to the Neo Viral Core, he can fuse with a human to evolve. The human remains in control of the body, while 007 is content to just sit and watch the ensuing carnage.

050 Seeker Roidmude

Portrayed by Kiyohito Yoshikai (voice), Kazuya Okada (suit), Haneyuri (human host)
A Spider-type Roidmude who, through the use of a Neo Viral Core, can amplify the hatred in people, causing them to rage against one another. He is searching a perfect candidate to record the fiercest anger, while the losers fall into comatose, having done so to over 80 people already, with a young woman named Yoriko being related to a missing person. When Go busts his fourth attempt, he's backed by Roidmudes 078 (Spider-type) and 082 (Cobra-type), but when Chaser comes in for the assist when Mach was getting mobbed by three Roidmudes, Mach loses it and goes after Chaser, as according to Seeker's plan. After Drive defuses the situation, the Roidmude attacks again at another complex, with Go working on stopping the rampages as Mach Tomarle. Once he found Yoriko's brother, the "brother" confesses he never had a sister, revealing the trap: Yoriko had worked with a Roidmude to find the fiercest anger, and found it in Go. Goading him into attacking them after fusing into Seeker, Chaser and Drive played interference, with Drive defusing the situation once more and goes on the offense. After beating Seeker hard enough as Type Formula Mantarn to separate Yoriko, real name Reiko Nishihori, and 050, allowing Drive to destroy the Roidmude and arrest the host.
  • Axe-Crazy: While 050 is stable, his host is deranged, suicidal, and psychotic.
  • Bitch in Sheep's Clothing: Reiko pretends to be a calm, sweet, caring sister to help better drive Go to madness.
  • The Bus Came Back: Seeker's human host returns in Kamen Rider Drive Saga: Kamen Rider Mach.
  • Combat Sadomasochist: Reiko likes it when Go's hurting her.
  • Fighter, Mage, Thief: The second of Neo-Viral Core evolved Roidmudes to evoke this, Seeker is modeled blatantly after a Mage.
  • Hate Plague: Zigzagged. He amplifies anger to find the fiercest anger, but those who don't meet his criteria just fall comatose.
    • One of the conduits of the Hate Plague is the mark on Seeker's hands, which can be transmitted like a virus through common touch.
  • Humans Are the Real Monsters: Says this in #27 after unleashing the Hate Plague, and provides an example of this in themselves by the inherent nature of Fusion Evolution Roidmudes.
  • Knight of Cerebus: While Seeker isn't too serious or funny on his own his host laughs madly as Go attacks her and tries to make sure Go crosses the Moral Event Horizon by killing her.
  • Killed Off for Real: Bites the dust by Drive Type Formula Mantarn's Trailer Impact.
  • Laughing Mad: Seeker's human host, when revealed of her true alignment, cackled like a witch, no matter how much punishment she was getting from Mach.
  • My Death Is Just the Beginning: Plot-wise, what Seeker did to Go is going to be expanded upon into the next arc.
  • Not So Different: Both human and host gloat that Go is no better than either of them. His Axe-Crazy rampage proves them right.
  • Red and Black and Evil All Over: As expected from a Roidmude who used a Neo Viral Core to evolve.
  • Strike Me Down with All of Your Hatred: Reiko wants Go to kill her so that she'll prove he's no better than her.

067 Open Roidmude

Portrayed by Yoshimasa Kawata (voice), Hajime Kanzaki (suit), Hiroaki Fukui (human host)
A Hybrid Evolution combined with Itsuro Neigishi, one of the robbers from a bank robbery that happened 12 years ago. Said robber happens to be the man responsible for the death of Shinnosuke's father, Detective Eisuke Tomari, making this personal. He has been on a crime spree robbing banks, each one caped with a dead employee. As it turns out, Open's true motive was to eliminate anyone involved with the robbery from 12 years ago, the attacks serving as a cover-up. He was found out, and 067 met his and at Chaser and Drive Type Formula's double Full Throttle attack, with Neigishi ending up in police custody.
  • Bank Robbery: His M.O., both in the past as a normal criminal and in the present as a Roidmude collaborator.
  • Brainwashed and Crazy: Shinnosuke suspects this when he notices a mark on Neigishi's neck that shows that he was a victim of 001's memory alteration powers.
  • Cop Killer: Allegedly the man who shot and killed Shinnosuke's father during a botched robbery 12 years ago.
  • Fighter, Mage, Thief: Completing the trio of the first three Roidmudes that evolved using the Neo-Viral Cores, he's the Thief, but actually he is an Assassin.
  • Heart Is an Awesome Power: His main power is to telekinetically open anything that can be opened. A very useful ability for a bank robber, but it's also very effective in a fight against the Riders.
  • Killed Off for Real: 067 met his end via Type Formula's Trailer Impact.
  • Open Sesame: Played with, as Open Roidmude can open anything that opens and closes by simply saying "Open", but it may be just a Verbal Tic.
  • Skeleton Key: He carries one, though he doesn't have to put it into any locks - he just have to turn it to unlock, well, anything.
  • Then Let Me Be Evil: Believing he no longer has a future due to his past as a cop killer, Neigishi freely sides with the Roidmudes. It isn't clear how much of this is his own decision, and how much is due to urging by 001.
  • We Used to Be Friends: He pursues his former partner, who doesn't understand how the man that was practically an older brother to him could change so much.
  • Would Hurt a Child: When a little girl began crying during the robbery, he tried to shoot her. Detective Eisuke shielded her at the cost of his own life. Turns out he didn't had it in him, so someone else did the deed...

106 Thief Roidmude

Portrayed by Anri Katsu (voice), Hajime Kanzaki (suit), Kisuke Iida (human host)

A Hybrid Roidmude responsible for stealing every bit of info and data relating to cases handled by Detective Eisuke Tomari, Shinnosuke's father.

For tropes associated with 106's human host, see Mitsuhide Nira.

  • Hook Hand: A huge one replaces his right arm...
    • Hooks and Crooks:... which can extend on a chain and be used on a distance to attack.
  • In the Hood: Thief has this as a part of his Roidmude form.
  • Giant Mook: After being split from his human host by Drive Type Tridoron's Technic-Hou Trailer Impact, Brain threw Bat Viral Core at him as distraction, while Brain and Nira escaped.
  • Legacy Character: After 106 is destroyed, Brain uses a Neo-Viral Core to fuse with the deceased Roidmude's human host. However, he did so only so that he could absorb the host's negative emotions to achieve his Ultimate Evolution.
    • Somewhat. Brain completely intended to fuse with Thief's human host, thinking that their shared emotion would make them unbeatable. His genuine shock at getting his Ultimate Evolution proves that his ascension was entirely accidental. Brain still uses this form for a while to hide his Ultimate Evolution from the heroes temporarily.
  • Killed Off for Real: 106 is killed by Drive via Booster Tridoron with a Max Flare Tire Extension. This does not mean the Thief Roidmude form is gone, however.
  • Walking Spoiler: Not the Roidmude, but rather his human host.

090 Cook Roidmude

Portrayed by Momoka Ayukawa (voice), Daisuke Satou (suit), Sonrei Yoshioka (human host)

A Hybrid Roidmude somehow related to the spontaneous combustion of several other Roidmudes. The SCU learns that the case has something to do with the famed underground restaurant Supreme. As it turns out, Cook is working with Medic to develop a serum to help Roidmudes achieve Ultimate Evolution, the serum also doubling as a heavenly sauce named Honfleur Sunset used at Supreme.

  • Bad Boss: When his underling protested using 090, Matsutaro Okumura fused with her and attacked him.
  • Chef of Iron: The food prepared by him is sublime, mostly thanks to the Hunfleur Sunset, and he can kick Rider ass no problem.
  • Hand Cannon: In reward for his services, Medic turns Cook left arm into such an appendage.
  • Love Makes You Evil: 090's human host goes along with the Roidmudes because he is in love with 090. This revelation causes Drive to hesitate when he manages to separate the pair, as the host pleads with him not to kill her.
  • Psycho Serum: While totally ineffective on humans (save for tasting absolutely delicious), Honfleur Sunset has this effect of Roidmudes. It drives them berserk and causes them to spontaneously combust after a period of time.
  • Wolverine Claws: Cook has three huge kitchen knives attached to his right arm.

008 Tornado Roidmude

One of the Executives who has returned from travelling around the world and successfully evolved into an Advanced Roidmude.

  • Affably Evil: While he and 006 seemed close to coming to blows, 008 is honored that Heart personally came to greet him upon his return.
  • Blessed with Suck: How he views his own evolution. He's glad that the desires of the human he's copied is helping him reach his Ultimate Evolution, but he is very quick to acknowledge that he views it as an incredibly stupid and shallow desire.
  • Blow You Away: As The Tornado Roidmude, it's only fitting for him to have aerokinesis.
  • Kill and Replace: Gloated that he killed George Shirogane while copying his mind and body.
  • Lightning Bruiser: Strong, fast, and durable, Tornado is a dangerous, well-rounded foe.
  • Monster of the Week: Finally revealed his Advanced Roidmude form in #39, and became a fodder victim in #40. These two episode also revolves around him making a move in an attempt to archive Ultimate Evolution.
  • Nice Hat: Wears a cowboy hat.
  • Super Speed: He's faster than Type Formula.
  • This Is a Drill: He can turn his arms into drill-like spears.
  • Walking the Earth: Based on his backpack and his comment that it's been a long time since he'd been in Japan, he'd apparently been doing this.
  • We ARE Struggling Together: Based on the tense conversation between him and 006, it's pretty clear that there's quite a bit of bad blood between them. Heart's arrival gets them both to cool off.

006 (Unknown) Roidmude

One of the Executives who has returned from overseas, with 062 and 036 as his lackeys. Like 008, he has successfully evolved into an Advanced Roidmude and prefers to keep it hidden for the time being. However, just before he could make use of it, his body was hijacked by Banno just as he tried to get rid of him.

  • Badass in a Nice Suit: Battles both Kamen Rider Chaser and Mach while still in his human form, and tosses them around easily.
  • Dance Battler: Fights like this during his ambush of Gou and Chase while attempting to recover the tab containing Professor Bannou.
  • Killed Off for Real: Dies in episode #41, when Banno separates 006's core from his body and destroys it.
    • Overlaps with The Unfought and Anticlimax Boss when for all of his boasts he never gets an appearance in his Advanced form, getting killed by Prof. Banno before ever getting the chance to.
  • Know When to Fold 'Em: When Mach manages to escape, 006 orders a withdrawal, since their primary objective (recovery of Brain's tab) has failed.
  • Tempting Fate: With Tornado gone, he proudly claims that he'll be the next Roidmude to achieve Ultimate Evolution. His body did, but after having his core removed first.
  • The Mafia: 006's bearing, outfit and bodyguards all combine to give him a distinctly gangster-ish image. However, unlike Heart's "one of the guys" air, 006 acts more like a Mafia don or Yakuza boss.
  • Opportunistic Bastard: While his main objective was the recovery of Professor Bannou, he decides to take advantage of the fact Chase happened to be there to take him out too.
  • We ARE Struggling Together: Based on the tense conversation between him and 008, it's pretty clear that there's quite a bit of bad blood between them. Heart's arrival gets them both to cool off.

108 Paradox Roidmude

Starring in Kamen Rider Drive: Surprise Future, he aims to create a permanent Global Freeze. For tropes specific to this Roidmude, see Kamen Rider Drive Movie Exclusive Characters.

099 Angel Roidmude

Potrayed by Mami Yamasaki (live), TBA (suit)

The Big Bad of Kamen Rider Drive Saga: Kamen Rider Chaser. One of the first Roidmudes who appears during the first Global Freeze. She later achieved her evolution as the Angel Roidmude. For tropes specific to this Roidmude, see Kamen Rider Drive Movie Exclusive Characters.

5886 Roidmude

The Big Bad of Kamen Rider Drive Saga: Kamen Rider Heart. A mysterious monster with the amalgamated appearance of all three Roidmude types. He appears two years after the Roidmude threat ended, targeting the previous Roidmudes' human templates. He attacks Medic's human template, Misuzu Hatori, and runs afoul of the newly revived Heart. For tropes specific to this Roidmude, see Kamen Rider Drive Movie Exclusive Characters.

     Reaper Legion
After Medic changed Chase's primary programming, and thus made him unable to continue his duties as a Reaper, she took upon herself to subdue rogue Roidmudes. For that reason she formed the Reaper Legion - a division of remodeled Low-Class Roidmudes of any type, who now serve as the enforcers of the Executives, with Medic as their leader. Thanks to the upgrades received from her, the members of the Legion are far more powerful combatants than your ordinary Low-Class Roidmude, and twice more ruthless.

The first two members of Medic's Reaper Legion are 044 and 094. After she defended herself from Drive Type Dead Heat Flare's Full Throttle by using them both as shields, she created a next batch as replacements, consisting of 034, 054 and 104. All three ended up destroyed by Mach, one being more immediate than the other two. 092 and 028 are later tasked with protecting 001, who expects to be attacked by Drive. They are swiftly dealt with by Kamen Rider Chaser.


005 Bat-type Roidmude/Revenger Roidmude

A Roidmude that appeared in two of the Bonus Episodes. Just before the Global Freeze, he was tangentially involved in a case Shinnosuke was investigating. He was beaten by Proto-Drive, but six months later Heart and Brain resurrected him to fight Drive. He can fly and is also able to combine with a gun to enhance its fighting capabilities.

  • Arm Cannon: Is able to fuse a handgun onto his right arm to create this.
  • Bat Out of Hell: Keeping its animal form without evolving.
  • BFG: Coming from its Handgun.
  • Big Bad: Of Secret Mission Type TV-KUN: Hunter & Monster! Chase the Mystery of the Super Thief!, Kamen Rider Drive: ~Mach Saga~, and Kamen Rider Drive Saga: Kamen Rider Mach.
  • Determinator: The guy wants his revenge, and keeps going despite the heroes more or less killing him several times over. Mach has to literally physically crush his Core after destroying his body again.
  • Jack the Ripoff: Its methods are an almost exact copy of the criminal from Episode 0, the Copycat Pirate, who himself was a Jack the Ripoff. 005 even uses the same warehouse. Justified, as he absorbed the Pirate's knowledge and he did it so he could draw out Shinnosuke, who previously faced the same criminal.
  • Killed Off for Real: Outed by Drive Type Speed Hunter and a combination Finishing Move by the Justice Cage and the Monster, where the combination crushed 005 into oblivion. Or so it seemed...
    • Finally Killed Off for Real this time in Kamen Rider Drive Saga: Kamen Rider Mach at the hands of Mach Chaser, having survived his previous defeat to Super Dead Heat Mach in Kamen Rider Drive: ~Mach Saga~.
  • Nice Job Fixing It, Villain!: According to Brain, Proto-Drive's defeat of 005 allowed to stop the Global Freeze. This is because Proto-Drive was able to recover 005's Viral Core, which let him access 005's memories.
  • Revenge: The human it copied wanted revenge on Shinnosuke, and the Roidmude itself wanted revenge on the Kamen Rider who beat it. Later, when he returns in Kamen Rider Drive Saga: Kamen Rider Mach, this is literally his motif, being the Revenger Roidmude.

051 Bat-type Roidmude

Portrayed by: Oga Taro

A Roidmude who became a robber. While Heart and Brain have no problems with Roidmudes committing crimes, they cannot afford them to make a ruckus. As the result, they, together with Chase, chase 051 into an abandoned warehouse to destroy him, sending him back to square one. He copied the data of a criminal, Toshio Miwa, the same human whose data was copied by Roidmude 077.

  • Arch-Nemesis: Has a small case of this with Chase. His body was destroyed not once, not twice, but three times by Chase himself. The first time was at the hands of Chase as Proto-Drive, the second time was by Mashin Chaser, and the third time, his body and core were destroyed by Super Mashin Chaser.
  • Bank Robbery: His "choice career". It didn't go well over the Executives. During Global Freeze and even after Brain reset him, his greed for money is still there.
  • Death of Personality: His first fate when the duo suspect he could be blowing their cover.
  • Defiant to the End: Didn't take his "sentence" lightly, and threw Paint under the bus (somewhat) while he was at it.
  • Killed Off for Real: Brutally killed by Chou Mashin Chaser's Full Break/Brake.
  • Killed Offscreen: His final fate happened sometime before the events of #43. Subverted when we see his death in the Chaser special, at the hands of Super Mashin Chaser.
  • Lower-Deck Episode: He returns in Drive Saga, and this time he's trying to take revenge against Chase, who has now become Kamen Rider Chaser.
  • Money Fetish: Has an obsession of having money to point the Executives find it problematic.

018 Spider-type Roidmude

Portrayed by: Marvin Jr.

After failing to deal with the riders, Gunman focuses on helping 018 evolve, with Chase tasked to back them up. 018 sells Density Shift Braces and feed on the customers' greed by absorbing the earned money while being guarded by Gunman and Chase, but unfortunately for them, their scheme was busted by Kamen Rider Mach and he was destroyed before he could evolve.

018 and Gunman's relationship are unique among the Roidmudes due to who they copied their human form with. Their disguise are based on a smuggling brothers where the younger one make business, while the older one acts as his bodyguard.

  • Fat Bastard: In his human form.
  • Four Eyes, Zero Soul: Again, in his human guise.
  • The Idiot from Osaka: His human form is based on the moneygrubbing variant.
  • Killed Off for Real: Was destroyed by Mach Magarl shooting down his Core at the same time as Gunman after the latter Rider destroyed their bodies as Mach Kaksarn with a Hit Macher Full Throttle from the Zenrin Shooter.
  • Nice Hat: Unique among other lower-class Roidmudes that he get to wear the same one in his human and Roidmude form.
  • Sibling Team: Turns out their human forms were copied from a pair of brothers.

069 Bat-type Roidmude

A Roidmude who copied and took both appearance and obsession of a stalker. This made him go after a model the stalker lusts after, only to get foiled by 096, who for some reason, chose to protect the model. At first, Brain wanted Chase to reset 069, but after a long struggle with the heroes, Brain opts to give him another chance, feeding 069 with 3 Bat Viral Cores and made him mutate into a Giant Bat Roidmude. When it kidnapped Kiriko, Chaser and Mach gave chase, while Drive was hanging on with thanks to Hooking Wrecker, Mach obtained the Ride Crosser, and used the new vehicle to fight against 069, eventually killing the Roidmude.

096 Bat-type Roidmude

Underneath a black cloak is a witch-like Roidmude who does fortune-telling with tarot cards. For some reason, it is protecting Lila Nanao, a fashion model, even going as far as stopping 069 who happened to be after her. Its first victim was a fat guy who never fails to pop in front of Lila just to give her gifts. 096 slashed him, turning him blue and putting him in a coma, leaving behind The Fool card. It then attacks 069's human partner after 069 was destroyed and Lila's Jerkass manager, leaving more cards to mark them as The Chariot and The Heirophant. Thanks to some good old detective works, it's revealed that 096 had contracted with Lila and took her grief and memories to fuel her evolution so Lila can be ignorant for accidentally causing Hiroki's death, but the Roidmude was bested and destroyed by the teamwork of Kamen Riders Drive and Mach.

  • Bat Out of Hell: Not that easy to see due to the black she wore under; but it's clearer in flashbacks and her last fight where she doesn't wear it.
  • Gender Bender: 096 was originally a masculine-speaking Roidmude. "He" became a "she" after The Reveal.
  • Femme Fatalons: It's right hand sported some nasty claws, although this trope comes into play after The Reveal.
  • Fortune Teller: Part of her motive, where she deals Tarot Cards.
  • Killed Off for Real: Was subjected to a Rider Double Kick from Drive Type Speed and Mach.
  • Monster of the Week: She is the main monster the heroes deal with throughout the arc.
  • Red Herring: We and the cast are led to believe that 096 based itself on Lila's missing fortune-telling boyfriend, when its human base is really Lila herself.
  • Tarot Motifs: She is first seen using a deck of Major Arcana to do fortune telling. She also left cards behind with her victims; The Fool for selfish love, The Chariot for egotism, and The Heirophant for meddling.

072 Bat-type Roidmude

A Roidmude that seems to be attacking a woman when first encountered by Drive and Mach. It then gets really excited upon seeing the Kamen Riders, like a nerd. This is because it took on the identity of the Special Unit's resident otaku Kyu Saijou. In fact, Saijou and the Roidmude have been coexisting peacefully for several months. Having absorbed Kyu's personality and memories, the Roidmude is mostly harmless. However, this means the Executors consider 072 defective, and he's killed by Medic.

  • Berserk Button: Being an Otaku Roidmude, it gets really mad over things like an anime having the wrong voice actor.
  • Harmless Villain: To comic levels.
  • Kill and Replace: Subverted. He was about to kill Kyu after copying his appearance, but after accepting his supposedly last request to watch the final episode of his favorite show, 072 was touched by it and relented, instead decided to live with Kyu instead.
  • Impaled with Extreme Prejudice: The fatal wound he receives from Medic.
  • The Knights Who Say "Squee!": He totally geeks out over seeing the Riders and watching Mach's big entrance, and is disappointed that Drive doesn't have his own dramatic announcement until he makes one up.
  • Otaku: To the point where it makes him mostly harmless.
  • The Power of Legacy: Inverted; before dying the Roidmude asks Drive to tell Kyu that he went crazy and was killed by Kamen Rider.
  • Token Good Teammate: For the Roidmude as a whole. The Roidmude are generally, as a rule, murderous and completely unconcerned about humanity. 072 is like this at first... until the person he copies, Kyuu, shows him an anime that convinces him to, instead of rampaging, casually live with Kyuu as his "twin." Even when he attacks someone, it's merely to lecture them, and Shinosuuke decrees he's proof not all Roidmude are bad, and he is furious when Medic kills him.
  • Twin Switch: With Kyu. A series of flashbacks show the Roidmude was present in previous episode.

027 Imitation Drive

Voiced by: Tomokazu Seki

A Cobra-type Roidmude who sold knock-offs of popular manga compilation Terebi-kun. When Kiriko and Shinnosuke investigate, he somehow manages to copy Drive's appearance and abilities (even hijacking Max Flare's tire when Shinnosuke attempts a Tire Change). He then escapes due to tricking Mach into attacking Drive, and then attempts to damage Drive's reputation. Mr. Belt and Rinna upgrade Drive into Drive Type High Speed to give Shinnosuke an edge over him.

  • Arson, Murder, and Jaywalking: His idea of ruining Kamen Rider Drive's reputation includes stealing bicycles and drawing graffiti. To Shinnosuke's outrage, Kiriko briefly falls for it despite her knowing there's a fake Drive out there.
  • Bavarian Fire Drill: When Mach arrives to assist Drive, Imitation Drive quickly points out that he's wearing Max Flare's tire, while the obviously fake Drive doesn't even have a regular tire. Mach (unaware that Imitation Drive had hijacked Max Flare during a Tire Change) agrees and attacks Drive while Imitation Drive flees. Shinnosuke is unamused by Gou's mistake.
  • Evil Doppelgänger: As his name indicates, this Roidmude is this to Drive Type Speed. He's even able to use Tire Change, though he pulls it off by simply shoving Drive out of the way when the Tridoron launches a tire.
  • Evil Is Petty: One of the crimes he commits while posing as the fake Drive is walking while texting.
  • Killed Off for Real: Destroyed by Kamen Rider Drive High Speed's Rider Kick.
  • Large Ham: And how! Subtle is not this Roidmude's strong point.
  • Poke the Poodle: The evil scheme this Roidmude launches? Selling cheap knock-offs of the magazine Terebi-kun, thus disappointing little boys and girls (and Kyu!) everywhere.

089 Shocker Buruburu

Portrayed by: Yuji Kishi

First seen as a Spider-type Roidmude who took the cells of deceased Shocker scientist Dr. D. Serves as the body for Shocker's Great Leader. Responsible for creating a dimensional distortion device that brought the Ninningers to Drive's world. After Youkai Buruburu is defeated, Kyuemon gives him the purified sealing shuriken, which he infused into himself allowing him to take the Youkai's form and turn into Shocker Buruburu.

Giant Bat Roidmude trio (026, 043, 087 Bat-Type Roidmudes)

Sent by Brain to stall Riders Drive and Chaser from interfering with Seeker's plan, these three Bat-type Low Class Roidmudes were given supercharged Viral Cores to intercept the airborne Kamen Riders in Booster Tridoron.
  • Bat Out of Hell: Natch.
  • Giant Mook: Mega-Natch.
  • Killed Off for Real: Unlike other times, the bodies and Cores of the Roidmudes were destroyed practically at the same time, so it's impossible to know which Roidmude bit it when they did.
    • One Giant Roidmude was killed when Kamen Rider Chaser gunned it out of the sky with his Ride Booster Blue.
    • The second was destroyed by Kamen Rider Chaser slamming his Ride Booster into it with help from a Shingou Axe slash.
    • The last one was blown away when Booster Tridoron unleashed its payload into it.

Low-class Roidmude sextet (038-040, 047-049)

When Nira and Brain's plan went pear shaped and ruined their reputations thanks to some , these 6 Roidmudes were called in to help with fighting against the Kamen Riders.
  • Conservation of Ninjutsu: These guys were beaten rather easily, considering that their Cores didn't explode from being hit from Full Throttle attacks, but enhanced attacks rather.
  • Killed Off for Real: 038, 039, and 040 were cut down by a enhanced sweeping slash by Chaser's Shingou Axe, and 047, 048, and 049 were offed by enhanced Zenrin Shooter strikes from Kamen Rider Deadheat Mach.
  • Rule of Three: Three Low Class Roidmudes fighting against Riders Deadheat Mach and Chaser.

077 Bat-type Roidmude (Beast Dopant)

A Roidmude who copied the data of Toshio Miwa, the same criminal who was copied by Roidmude 051. He made his way to Fūto City and attempted to use a Gaia Memory, which didn't go so well for him the first time around. The second time, on the other hand...
  • Bat Out of Hell
  • Big Bad Ensemble: He's the main antagonist for the subplot/crossover of Kamen Rider Drive Saga: Kamen Rider Chaser. However, the Big Bad for the main plot of that special is Roidmude 099, who is unconnected to him.
  • Hybrid Monster: Roidmude 077 becomes a Roidmude/Dopant hybrid.
  • Killed Off for Real: He's defeated by Drive's SpeeDrop and his Gaia Memory is presumably detroyed by Accel's Accel Glanzer.
  • Legacy Character: He becomes the second Beast Dopant.
  • Lower-Deck Episode: He appears in the Kamen Rider Drive Saga: Kamen Rider Chaser special.
  • Phlebotinum Overload: His first attempt at using a Gaia Memory caused him to collapse. It probably has something to do with him being a mutant android trying to plug something made for organic bodies into himself. It goes better the second time he tries, likely because Roidmudes are made to copy humans and evolve from that data.
  • Red Eyes, Take Warning: His eyes glow red just as he reverts from his human disguise to his Roidmude form.
  • Screw This, I'm Outta Here!: Once he successfully becomes the Beast Dopant, he tries to make a run for it, but Shinnosuke, Gō, and Ryū don't let him get very far.
  • Transformation Trinket: 077 uses the Beast Gaia Memory.
