List of Kamen Rider Drive characters

Kamen Rider Drive (仮面ライダードライブ) is a Japanese tokusatsu series that serves as the 25th installment in the Kamen Rider franchise and the 16th entry in the Heisei era. The series follows police officer Shinnosuke Tomari after he is chosen by an advanced artificial intelligence called Mr. Belt to become the titular Kamen Rider Drive to battle the Roidmudes, androids that wish to usurp humanity as the dominant species on Earth through their ability to slow the passage of time.

Shinnosuke Tomari
Shinnosuke Tomari (泊 進ノ介) is a detective of the Metropolitan Police's First Investigation Division who seeks to solve the mystery behind his father, Eisuke Tomari's, death. Prior to the series, amidst the "Global Freeze", Shinnosuke accidentally abandoned his partner, Akira Hayase, who was left critically injured. Upon hearing of this, the former lost all motivation to be a police officer and was transferred to the Special Investigations Division. After encountering Mr. Belt, Shinnosuke secretly becomes Kamen Rider Drive to combat the Roidmudes, who caused the Global Freeze. Following the Roidmudes' defeat and the Special Investigations Division's disbandment, Shinnosuke is promoted to police sergeant and transferred back to the First Investigation Division. As of the crossover films Kamen Rider × Kamen Rider Ghost & Drive: Super Movie War Genesis and Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Rider and the V-Cinema Drive Saga: Kamen Rider Mach, Shinnosuke goes on to marry his Special Investigations partner, Kiriko Shijima, and have a son named Eiji.

Utilizing one of several Shift Cars (シフトカー) in conjunction with the Drive Driver (ドライブドライバー) belt and the Shift Brace (シフトブレス), Shinnosuke can transform into Kamen Rider Drive. Unlike most Kamen Riders, his personal vehicle is the Tridoron (トライドロン) sports car, which has alternate dune buggy and garbage truck forms and can combine with a pair of Ride Booster (ライドブースター) go-karts to form the Booster Tridoron (ブースタートライドロン) hovercraft. While transformed, he wields the Handle-Ken (ハンドル剣) and the Door-Ju (ドア銃), can perform Full Throttle (フルスロットル) finishers, is immune to the Roidmudes' Heavy Acceleration fields, and can use other Shift Cars to either perform a Tire Exchange (タイヤ交換) technique and grant himself unique abilities or assume alternate Type (タイプ) forms, which are as follows:


 * Type Speed (タイプスピード): Shinnosuke's sports car-themed default form accessed from the Shift Speed (シフトスピード) Car that grants increased speed and agility.
 * Type High Speed (タイプハイスピード): A luxury car-themed version of Type Speed accessed from the Shift High Speed (シフトハイスピード) Car that grants similar capabilities as Type Speed. This form appears exclusively in the DVD special Type TV-Kun Hunter & Monster! Chase the Mystery of the Super Thief!
 * Type Wild (タイプワイルド): A dune buggy-themed auxiliary form accessed from the Shift Wild (シフトワイルド) Car that grants increased strength and durability.
 * Type Technic (タイプテクニック): A garbage truck-themed auxiliary form accessed from the Shift Technic (シフトテクニック) Car that grants increased accuracy and precision.
 * Type Deadheat (タイプデッドヒート): A motorcycle/sidecar-themed fusion form accessed from the Shift Deadheat (シフトデッドヒート) Shift Car/Signal Bike hybrid, which is shared with Kamen Rider Mach, that allows the user to emulate Heart's Dead Zone, but has a side effect that renders them uncontrollable after extended use, and grants immunity to the Super Heavy Acceleration fields, but with the drawback of their enhanced capabilities being limited.
 * Kamen Rider Super Deadheat Drive (仮面ライダー超デッドヒートドライブ): The evolved form of Type Deadheat accessed from the Tridoron Key (トライドロンキー), which serves as a backup for Mr. Belt's consciousness and allows the user to control the Tridoron, in conjunction with the Mach Driver Honoh. This form appears exclusively in the film Kamen Rider Drive: Surprise Future.
 * Kamen Rider Deadheat Drive (仮面ライダーデッドヒートドライブ): A variant of Type Deadheat accessed from the Shift Deadheat Shift Car/Signal Bike hybrid in conjunction with the Mach Driver Honoh that grants similar capabilities as Type Deadheat. This form appears exclusively in the crossover film Kamen Rider × Kamen Rider Ghost & Drive: Super Movie War Genesis.
 * Type Formula (タイプフォーミュラ): Shinnosuke's Formula One car-themed super form accessed from the Shift Formula (シフトフォーミュラ) Car that grants supersonic speed, aerokinesis, immunity to the Super Heavy Acceleration fields, and the use of three pit crew-themed Shift Cars. In this form, he wields the semi-trailer truck-like Trailer-Hou (トレーラー砲) rifle.
 * Type Tridoron (タイプトライドロン): Shinnosuke's ultimate form accessed from the Shift Tridoron (シフトトライドロン) Car, which transforms the Tridoron into increased armor, that grants the use of the Tire Blending (タイヤカキマゼール) ability to fuse three Tire Exchange Shift Cars of a certain type into a singular one with their combined powers. If necessary, Mr. Belt can assume control of the form.
 * Type Fruits (タイプフルーツ): A samurai/orange-themed special form accessed from the Shift Fruits (シフトフルーツ) Car that grants proficiency in sword fighting. In this form, Shinnosuke dual wields Kamen Rider Gaim's Musou Saber and Daidaimaru. This form appears exclusively in the crossover film Kamen Rider × Kamen Rider Drive & Gaim: Movie War Full Throttle.
 * Type Special (タイプスペシャル): A futuristic car-themed fusion form accessed from the dark blue-colored Special (スペシャル) side of Eiji Tomari's Shift Next Special Car that combines the powers of the present and future Kamen Rider Drives. This form appears exclusively in the film Kamen Rider Drive: Surprise Future.
 * Kamen Rider Zero Drive (仮面ライダーゼロドライブ): A prototypical version of Kamen Rider Proto Drive. This form appears exclusively in the crossover film Kamen Rider × Kamen Rider Ghost & Drive: Super Movie War Genesis.

Shinnosuke Tomari is portrayed by Ryoma Takeuchi (竹内 涼真). As a child, Shinnosuke is portrayed by Ryohei Aoki (青木 綾平).

Mr. Belt
"Mr. Belt" (ベルトさん) is an artificial intelligence (AI) who was originally Krim Steinbelt (クリム・スタインベルト), a human scientist who created the Core Driviars (コアドライビア), the technology used in Kamen Rider Drive's Shift Cars and Tridoron as well as his colleague Tenjuro Banno's Roidmudes, who killed him and led to him uploading his consciousness into the Drive Driver. During the Global Freeze, Mr. Belt worked with Proto Zero as Kamen Rider Proto Drive to combat the Roidmudes until the latter's apparent death. In the intervening months, Mr. Belt upgraded the Drive arsenal until he is found by and chose Shinnosuke Tomari to become Kamen Rider Drive because of the officer's tendency to act first without hesitation. Mr. Belt continues to fight alongside Tomari and the Special Investigations Division until Banno and the Roidmudes are eventually defeated. Following this, Mr. Belt bids farewell to his allies before sealing himself and the Drive arsenal beneath the Kuruma Driver's License Center to prevent them from falling into the wrong hands by the series finale, though he returns twice to help Shinnosuke during the events of the crossover films Kamen Rider × Kamen Rider Ghost & Drive: Super Movie War Genesis and Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Rider.

Mr. Belt is voiced by Chris Peppler (クリス・ペプラー), who also portrays Krim Steinbelt and serves as the series narrator.

Kiriko Shijima
Kiriko Shijima (詩島 霧子) is an athletic officer in the Special Investigations Division who tries to maintain a serious exterior by refusing to smile and working with mechanical precision, though she loses her composure whenever Shinnosuke points out the times she does smile and is forced to physically drag him back to work when he slacks off, often handcuffing him in the process. After being attacked by the Paint Roidmude and rescued by Kamen Rider Proto Drive during the Global Freeze, she attempts to become Kamen Rider Drive. Due to being incompatible however, she assists Shinnosuke as Drive in the field and is, as such, initially the only member of the division who is aware of his secret identity. Additionally, she was aware of her father, Tenjuro Banno's, evil despite not knowing him personally and did her best to protect her brother Go from the truth. She would later help Chase recover his memories upon learning he was Proto Drive and, following the Special Investigations Division's disbandment, join Shinnosuke in the First Investigation Division. As of the crossover films Kamen Rider × Kamen Rider Ghost & Drive: Super Movie War Genesis and Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Rider and the V-Cinema Drive Saga: Kamen Rider Mach, Kiriko goes on to marry Shinnosuke and have a son named Eiji.

Kiriko Shijima is portrayed by Rio Uchida (内田 理央). As a child, Kiriko is portrayed by Yui Kato (加藤 結).

Heart
The Heart Roidmude (ハートロイミュード), also known simply as Heart (ハート) and formerly known as Roidmude 002 (ロイミュード002), is a jovial and hedonistic yet imposing namesake-themed Spider-Type Roidmude and the field leader of the Roidmude forces stationed in Japan. He refers to his fellow Roidmudes as his friends, desires a worthy opponent to fight, and can assume the human guise of Shinzo Hiroi (広井 真蔵), a businessman who refused to invest in Heart's creator, Tenjuro Banno's, research. Years prior to the series, he was tortured by Banno before eventually joining Freeze and Brain in killing him and Krim Steinbelt, though Heart was left with a hatred for humanity.

In the present, Heart finds his rival in Shinnosuke Tomari, admiring his strength and honor, and uses this to achieve his Over-Evolved form. After learning Banno survived, Heart breaks off from his fellow Roidmudes to focus on killing him permanently, to the detriment of all else and refusing to forgive humanity as a result. However, he is forced to work with Banno after the latter takes Medic and a member of the Grim Reaper Unit hostage. When Brain sacrifices himself to save Medic, Heart helps the Kamen Riders defeat Banno and destroy the Sigma Circular before attempting to face Shinnosuke in a final battle, refusing to let go of his grudge. Nonetheless, Shinnosuke makes his peace with the dying Roidmude.

Two years later, during the events of the V-Cinema Drive Saga: Kamen Rider Heart, Heart is revived by Go Shijima, Rinna Sawagami, and Kyu Saijo, who intended to revive Chase, with Brain and Medic's Cores within him. After learning of Roidmude 5886 attacking the various human templates the Roidmudes mimicked or fused with and seeking redemption for his and his kind's crimes, Heart volunteers to help stop it, but is unable to regain the full potential of his former Roidmude power. Instead, he uses the Shift Heartron (シフトハートロン) Car in conjunction with copies of the Drive Driver and Shift Brace to transform into Kamen Rider Heart (仮面ライダーハート) and combine his power with Brain and Medic's in order to defeat 5886, though their Cores are overloaded and they are destroyed once more. Despite this, a changed Heart dies believing humans and Roidmudes can coexist.

In his Roidmude form, Heart can strengthen himself via joy as his emotional catalyst and possesses heat absorption, the ability to adapt to opponents' power and strategies once he has fought them once, the ability to grow stronger over time, illusion casting, an ability called the Dead Zone (デッドゾーン), which grants uncontrollable overwhelming combat capability and the ability to generate energy blasts, though it will cause him to explode over time and damage him. After Medic modifies him, he gains the ability to generate a Super Heavy Acceleration (超重加速) field, which freezes everything within its vicinity, such as humans and Shinnosuke in his regular forms.

As Kamen Rider Heart, he initially assumed the mismatched, hastily-made Type Speed Wild Technic (タイプスピードワイルドテクニック) form due to Brain's compiled data on their battles with Shinnosuke. After regaining his Roidmude power, Heart is able to assume his true form, Type Miracle (タイプミラクル), which grants the use of the Viral Blending (バイラルカキマゼール) ability to combine his, Brain, and Medic's powers.

Heart is portrayed by Tomoya Warabino (蕨野 友也).

Brain
The Brain Roidmude (ブレンロイミュード), also known simply as Brain (ブレン) and formerly known as Roidmude 003 (ロイミュード003), is a cold, arrogant, calculating, and stoic namesake-themed Bat-Type Roidmude who is responsible for collecting and managing information on their kind, resetting rogue members, and serving as Heart's advisor. Detesting chaos and unruly behavior, even amongst his comrades, he is easily irritated by the brash and disorderly Advanced Roidmudes and the idea that they seem to be the most powerful. Additionally, he sees the Kamen Riders as a threat to the Roidmudes' goal. Initially assuming the identity of the intelligence agency's programming deputy director Mitsuharu Kineta (杵田 光晴) after escaping into cyberspace during the Global Freeze, Brain later assumes the alias of Sou Noumi (能見 壮), a consultant from a Paranormal Science Institute, to help Freeze hinder the Special Investigations Division's efforts to stop the Roidmudes and get Shinnosuke Tomari suspended from the police force.

Following Freeze's death, Brain uses a Neo Viral Core to fuse with Mitsuhide Nira, who was envious of Shinnosuke's father, Eisuke Tomari, to achieve his Over-Evolved form. However, the Roidmude is defeated by Kamen Riders Drive, Mach, and Chaser and subsequently tortured by Medic for his failure. After witnessing Tenjuro Banno's return as Gold Drive and warning Heart of Medic being under Banno's control, Brain goes into hiding to prevent himself from being used in Banno's plot to enact a second Global Freeze, leading to Brain entering the Special Investigations Division's protective custody. Ultimately, Brain chooses to help Heart save Medic by sacrificing himself to power Banno's Sigma Circular in her place.

During the events of the V-Cinema Drive Saga: Kamen Rider Brain, Go Shijima reconstitutes Brain, Heart, and Medic's consciousnesses while attempting to revive Chase. Following this, Brain dreams of becoming Kamen Rider Brain (仮面ライダーブレン) via the Brain Driver (ブレンドライバー) belt and fighting the Mu (無) organization to prevent them from wiping out individuality on Earth.

During the events of the web-exclusive crossover series Kamen Rider Outsiders, Brain is revived by Foundation X as a Humagear.

In his Roidmude form, Brain can attack a target's nervous system via a powerful neurotoxin, hack technology by tapping his glasses, and strengthen himself via envy as his emotional catalyst. Additionally, he used a tablet to keep track of the Roidmudes, though he was unaware of Banno's consciousness being within it until the mad scientist became Gold Drive. In his Over-Evolved form, Brain possesses ESP, the use of psionic attacks, poisonous tentacles, and data manipulation. As Kamen Rider Brain, he retains his Roidmude powers while gaining the use of the Brain Megane Blade (ブレンメガネブレード) sword and the Ride Braiser (ライドブレイザー) motorcycle. He can also perform the Rider Poison Hands (ライダー毒手) and Poison Handkerchiefs (ポイズンハンカチーフ) attacks, which allow him to secrete 999 types of toxicants, and the Brain Head Crusher (ブレンヘッドクラッシャー) Full Throttle.

Brain is portrayed by Shota Matsushima (松島 庄汰).

Chase
Chase (チェイス), also known as Roidmude 000 and Proto Zero (プロトゼロ), is a soft-spoken specially modified Roidmude created to serve as Krim Steinbelt's aide. During the Global Freeze, Chase attempted to stop the Roidmudes as Kamen Rider Proto Drive before he was captured and reprogrammed by Freeze, Heart, and Brain to work for them as their "Grim Reaper" (死神), Mashin Chaser, while adopting the form of traffic police officer Koichi Kano as a civilian disguise. With no recollection of his past save for a directive to protect humans, Chase is tasked with destroying rogue Roidmudes' bodies and taking their numbers so Brain can reset them, developing a rivalry with Shinnosuke in the process and slowly regaining his memories. In response to the latter, Medic reprograms Chase to protect Roidmudes instead of humans, during which he develops a separate rivalry with Go Shijima until he is eventually defeated by Shinnosuke. Presumed dead, Kiriko finds and nurses Chase back to health in return for him saving her during the Global Freeze.

Initially torn over whether to be a Roidmude or a Kamen Rider, he chooses to become the latter after Kiriko gives him to the means to become Kamen Rider Chaser and attempts to become more human after learning of human emotions. Along the way, he develops an attraction towards her, though he realizes she loves Shinnosuke and continues to bear an unrequited love for her to become closer to being human. Amidst Tenjuro Banno's attempt to enact a second Global Freeze, Chase joins forces with Go to stop him, sacrificing himself in the process. Following this, Go takes Chase's Signal Chaser Bike with him to the U.S. in the hopes of reviving him someday.

Throughout the series, Chase has assumed the following forms:
 * Kamen Rider Proto Drive (仮面ライダープロトドライブ): Chase's concept car-themed original Rider form and the prototypical version of Kamen Rider Drive accessed from the Shift Speed Prototype (シフトスピードプロトタイプ) Car in conjunction with the Drive Driver and Shift Brace.
 * Mashin Chaser (魔進チェイサー): Chase's Kamen Rider-esque warrior form accessed from the Break Gunner (ブレイクガンナー) firearm, which can switch between Gun Mode (ガンモード) and Break Mode (ブレイクモード), that grants the use of three Chaser Viral Cores (チェイサーバイラルコア), which allow him to augment himself into Tune Chaser (武装チェイサー). His personal vehicle is the Ride Chaser (ライドチェイサー) motorcycle, which can combine with the Ride Macher to form the Ride Crosser (ライドクロッサー) car.
 * Super Mashin Chaser (超魔進［マシン］チェイサー): The evolved form of Mashin Chaser accessed from the Rhino Super (ライノスーパー) Viral Core in conjunction with the Break Gunner that grants the use of the Rhino Strizer (ライノストライザー) blade. This form appears exclusively in the V-Cinema Drive Saga: Kamen Rider Chaser.
 * Kamen Rider Chaser (仮面ライダーチェイサー): Chase's motorcycle-themed second Rider form accessed from the Signal Chaser (シグナルチェイサー) Bike in conjunction with the Mach Driver Honoh that grants the use of the pedestrian signal-like Shingou-Axe (シンゴウアックス) and the Ride Booster Blue (ライドブースターブルー) go-kart while retaining the use of his Break Gunner and Ride Chaser. While transformed, he can use a repaired version of the Shift Speed Prototype Car to grant himself superhuman speed.

Chase is portrayed by Taiko Katono (上遠野 太洸), who also portrays Koichi Kano, while Proto Drive is voiced by Daichi Endō (遠藤 大智) in Drive Saga: Kamen Rider Chaser.

Go Shijima
Go Shijima (詩島 剛) is Kiriko's younger brother who lived in the United States for some time, working as a freelance photographer, before eventually returning to Japan to fight the Roidmudes as Kamen Rider Mach (仮面ライダーマッハ), who uses Signal Bikes (シグナルバイク) as opposed to Drive's Shift Cars. Having dedicated himself to destroying his father, Tenjuro Banno's, work, Go displays a hatred for the Roidmudes and develops a rivalry with Chase before eventually warming up to him. Upon learning Banno's consciousness is stored in Brain's tablet computer, Go pretends to betray his allies to get closer to the Roidmude leaders and rescue him while working undercover as "Mr. X" to covertly help the Special Investigations Division. After eventually rescuing Banno however, Go discovers the former used him in a plot to enact a second Global Freeze and joins forces with Chase to stop him before returning to America in the hopes of reviving Chase, becoming a famous photographer along the way.

In the tie-in novel Kamen Rider Drive: Mach Saga, Go's grudge against the Roidmudes is revealed to have stemmed from Roidmudes 017 and 018 killing his friend Ethan Woodward (イーサン・ウッドワード) and Go being unable to save him. Afterward, Professor Harley Hendrickson rescued Go and prepared him to face the Roidmudes. In the present, Go develops a mutual attraction towards Reiko Nishiori due to their similar backgrounds and battles the Revenger Roidmude after the latter contributes to Reiko's father's death, seemingly destroying the monster. During the events of the V-Cinema Drive Saga: Kamen Rider Mach, Go works to find proof of Reiko's innocence after the Revenger Roidmude frames her for his crimes and permanently destroys the Roidmude, clearing her name and entering a relationship with her.

Utilizing the Signal Mach (シグナルマッハ) Bike in conjunction with the Mach Driver Honoh (マッハドライバー炎) belt, Go can transform into Kamen Rider Mach. While transformed, he gains the use of the Next System (ネクストシステム), which allows to utilize Signal Bikes and Shift Cars, and wields the Zenrin Shooter (ゼンリンシューター) handgun. His personal vehicles are the Ride Macher (ライドマッハー) motorcycle and the Ride Booster Red (ライドブースターレッド) go-kart. Similarly to Drive, most of Go's Signal Bikes allow him to perform a Signal Exchange (シグナル交換) technique and grant himself unique abilities while some allow him to assume alternate forms, which are as follows:


 * Kamen Rider Deadheat Mach (仮面ライダーデッドヒートマッハ): A motorcycle/sidecar-themed fusion form accessed from the Shift Deadheat Shift Car/Signal Bike hybrid, which is shared with Kamen Rider Drive, that grants similar capabilities as Type Deadheat. Unlike Shinnosuke, Go later manages to overcome the Dead Zone's negative side effects.
 * Kamen Rider Super Deadheat Mach (仮面ライダー超デッドヒートマッハ): The evolved form of Deadheat Mach accessed from the Shift Viral Core (シフトバイラルコア) in conjunction with a prototype Mach Driver Honoh. This form appears exclusively in the tie-in novel Kamen Rider Drive: Mach Saga.
 * Kamen Rider Chaser Mach (仮面ライダーチェイサーマッハ): A fusion form between Kamen Riders Mach and Chaser accessed from the latter's Signal Chaser Bike that grants the use of his Shingou-Axe and Mashin Chaser's Viral Cores.
 * Kamen Rider Mach Chaser (仮面ライダーマッハチェイサー): The evolved form of Chaser Mach accessed from the Shift Ride Crosser (シフトライドクロッサー) Car. This form appears exclusively in the V-Cinema Drive Saga: Kamen Rider Mach.

Go Shijima is portrayed by Yu Inaba (稲葉 友). As a child, Go is portrayed by Ryu Hashizume (橋爪 龍).

Medic
The Medic Roidmude (メディックロイミュード), also known simply as Medic (メディック) and formerly known as Roidmude 009 (ロイミュード009), is a heartless namesake-themed Cobra-Type Roidmude who assumed the form of Misuzu Hatori (羽鳥 美鈴), a human ballerina who was left hospitalized, paralyzed, and amnesiac following a car crash. While taking part in the Global Freeze, Medic found and nursed an injured Heart back to health, but entered a catatonic state when the event ended.

In the present, Volt gives his life to contribute to Medic's revival, allowing her to help Heart and Brain achieve their Over-evolved forms, reprogram Chase to become the Roidmudes' defender after he slowly regains his memories as Proto Zero, and create the Grim Reaper Unit to take his place in helping Brain reset rogue Roidmudes. Despite taking on Hatori's kindness, Medic's emotions became twisted as a result of synchronizing with other Roidmudes, which manifests as her alternating between nurse/ballerina-inspired attire and Gothic Lolita-inspired attire in her human form based on whether Hatori's kindness or the other Roidmudes' collective minds hold the most influence on her. After Tenjuro Banno resurfaces as Gold Drive, he manipulates Medic into facilitating his scheme to enact a second Global Freeze, though her loyalty to Heart causes her to achieve her Over-Evolved form. Banno reprograms her to obey him instead so he can use her to power his Sigma Circular. However, Brain sacrifices himself to save her, causing her to regain her memories and rejoin Heart to stop Banno before she is destroyed by the Sigma Circular.

In combat, Medic can use feelings of devotion to strengthen herself, produce healing energy from her hands, which has the side effect of causing her to absorb targets' emotions, absorb Roidmudes' Cores for transportation purposes, teleport, alter other Roidmudes' programming, produce scalpel-tipped tentacles from her shoulders in both her human and Roidmude forms capable of penetrating Roidmudes' bodies and destroying their Cores, fire a scalpel beam, produce human clones, and enhanced vision. In her Over-Evolved form, she possesses aero- and ergokinesis and superhuman strength.

Medic is portrayed by Fumika Baba (馬場 ふみか).

Roidmudes
The Roidmudes (ロイミュード) are 108 androids that wish to usurp humanity as Earth's dominant species. Designed by Professor Tenjuro Banno as life forms capable of evolving like and mimicking humans 15 years prior to the series, his friend and colleague, Krim Steinbelt unwittingly provided him with prototype Core Driviars to complete their development. Following their activation six months prior to the series, the Roidmudes launched a full-scale attack on Northeastern Asia in an event called the Global Freeze (グローバルフリーズ). In the present, the Roidmudes operate in the shadows to pursue varying individual agendas and create four Over-Evolved Roidmudes and find the "Promised Number" even as their numbers are reduced by Kamen Riders Drive, Mach, and Chaser, among others. If a Roidmude works against their plan, the leading members will have the dissenter's body destroyed so their Core can be reset back into line. Upon learning of Banno's plot to sacrifice four of them to the Sigma Circular to instigate a second Global Freeze across the rest of the world, several of the Roidmudes help the Riders thwart him, resulting in most of the androids' destruction.

Roidmudes possess the ability to produce Heavy Acceleration (重加速) fields, which is colloquially referred to as "Heaviness" (どんより) and drastically decelerates everything around them, with victims caught in the fields describing it as the sudden physical sensation of slowed time. To sustain, empower, and evolve themselves, the Roidmudes use devices called Viral Cores (バイラルコア). All Roidmudes possess a Core (コア), which contains their essence, and start out as Plain Roidmudes (プレーンロイミュード), which are divided between the following variations: Cobra-Types (コブラ型), which possess superhuman strength; Spider-Types (スパイダー型), which can cling to walls and ceilings as well as produce spider silk; and flight-capable Bat-Types (バット型). As long as their core remains intact, the Roidmudes can survive losing a physical body and revive themselves with a Viral Core.

If Plain Roidmudes copy the appearances and memories of a particular target and gain enough information, they can evolve into Advanced Roidmudes (上級ロイミュード), gaining a distinct personality reflecting their new individualized form and the ability to spread their Heavy Acceleration fields across multiple city blocks. If they absorb multiple Viral Cores at once, they can transform into Giant Roidmudes (巨大ロイミュード), which resembles their base Viral Core.

Following Chase's defection, Freeze develops Neo Viral Cores (ネオバイラルコア), which allow Roidmudes to fuse with a human and instantly assume a red-colored Fusion Evolved Form (融合進化態) via symbiosis. If a Roidmude forms a connection with a particular emotion and exceeds a certain limit, they can evolve into a gold-colored Over-Evolved Form (超進化態).

Freeze
The Freeze Roidmude (フリーズロイミュード), also known simply as Freeze (フリーズ) and formerly known as Roidmude 001 (ロイミュード001), is an ice/snow-themed Cobra-Type Roidmude, the leader of the Roidmude forces, and one of Tenjuro Banno's earliest creations who joined Heart and Brain in killing Banno and Krim Steinbelt before causing the Global Freeze as Freeze has the ability to create the strongest Heavy Acceleration field, even in his original form. Not long afterwards, Freeze assumed the form of Soichi Makage (真影 壮一), secretary of the National Bureau of Defense (国家防衛局), to watch over the police force and evolved into his Advanced form.

In the present, he creates Neo Viral Cores to bolster the Roidmudes in their fight against the Kamen Riders and fights to personally remove Shinnosuke Tomari from the police force while using him to complete his evolution. While Freeze succeeds in attaining his Over-Evolved form using humiliation as his emotional catalyst and killing Shinnosuke, the latter's allies revive him so he can destroy Freeze in retaliation for seemingly killing his father, Eisuke Tomari, though Freeze reveals it was Mitsuhide Nira instead before he dies.

In his Advanced form, Freeze possesses cryokinesis and the ability to produce snowflakes capable of suppressing memories, though Eisuke proved immune. In his Over-Evolved form, Freeze can fly, generate snowstorms, and produce energy blasts and shields.

Freeze is portrayed by Masami Horiuchi (堀内 正美).

Roidmude 004
Roidmude 004 (ロイミュード004) is a Spider-Type Roidmude and Tenjuro Banno's right-hand man who copied Krim Steinbelt's appearance before the Global Freeze, though 004's mind became corrupted and he was deactivated. In the present, Banno reactivates 004 to serve as his subordinate and pose as a future version of Steinbelt who became the ruler of a Roidmude dominant Earth. After being defeated in battle by Kamen Rider Drive, 004 attempts to destroy the Kamen Riders, Medic, and Heart by self-destructing, but Kamen Rider Deadheat Mach protects them before 004 explodes.

In a possible future time period depicted in the film Kamen Rider Drive: Surprise Future, 004 planted a chip in Mr. Belt that allowed the Roidmudes to take over Earth after Shinnosuke destroyed the latter. By 2035, 004 became the leader of an army of blank Roidmudes and tasked Roidmude 108 with going back in time to ensure their future comes to pass.

Roidmude 004 is portrayed by Chris Peppler, who also portrays Krim Steinbelt and voices Mr. Belt.

Grim Reaper Unit
The Grim Reaper Unit (死神軍団) is a cockroach-themed division of remodeled Plain Roidmudes who serve as Medic's subordinates and are armed with Hell Scythes (ヘルサイス), guns, and claws. Medic creates them to take over Mashin Chaser's duty of eliminating rogue Roidmudes, destroying them completely instead of resetting them.

Minor Roidmudes

 * Roidmude 029 (ロイミュード029): A Cobra-Type Roidmude who has a habit of picking up other people's traits, assumed the identity of Nobuo Masuda (益田 信夫), and sneaks into public places such as gyms and talent agencies to find ideal humans to emulate before ambushing a target to add their traits to his human guise. After being defeated by Kamen Rider Drive, Heart gives 029 a Viral Core, transforming him into the human body-themed Iron Roidmude (アイアンロイミュード). In his new, upgraded body and after copying several human body parts, 029 gains the ability to stretch his arms. However, he is destroyed by Drive. Roidmude 029 is portrayed by Masafumi Yokoyama (横山 真史).
 * Paint Roidmude (ペイントロイミュード): A namesake/artist-themed Spider-Type Roidmude, formerly known as Roidmude 010 (ロイミュード010) who possesses the ability to convert victims into colorful, paint-like data streams, fire paint-based projectiles, and extendable paint tube-like arms. During the Global Freeze, Paint attacked Kiriko Shijima as part of his desire to capture women in his paintings, but was repelled by Kamen Rider Proto Drive. In the present, Paint assumes the identity of Kazuhiro Asaya (浅矢 一広), establishes an art gallery to store all of his victims, and gains Roidmude 084's help in undergoing a mass kidnapping spree. However, Paint is eventually exposed and destroyed by Kamen Rider Drive, which restores his victims. The Paint Roidmude is portrayed by Lou Oshiba (ルー大柴).
 * Roidmude 084 (ロイミュード084): A Spider-Type Roidmude and associate of Paint's who assumes the guise of Kazuhiro Asaya's student, Hajime Fujimiya (富士宮 肇) and possesses a similar version of Paint's conversion ability, though 084's streams manifest as monochrome pencil sketches. 084 assists Paint in his kidnapping spree until the former is destroyed by Kamen Rider Drive. Roidmude 084 is portrayed by Yūta Murakami (村上 雄太).
 * Crash Roidmude (クラッシュロイミュード): A hammer-themed Cobra-Type Roidmude, formerly known as Roidmude 023 (ロイミュード023), who assumes the identity of a criminal named "Crash" and possesses large, twin arm-mounted hammers. He and his "brothers", Roidmudes 060 and 074, target the Font Earl company's armored vehicles for their explosives so they can commit a major heist. Despite Kamen Rider Drive destroying 060, Crash and 074 succeed in stealing the explosives, but are ultimately destroyed by Kamen Rider Drive and the Tridoron respectively. The Crash Roidmude is portrayed by HIRO of Yasuda Dai Circus.

Before his death, Tojo transferred his mind into Cyberoid ZZZ, obtains a variant of the Break Gunner called the Lupin Gunner (ルパンガンナー), and goes on a crime spree as Kamen Rider Lupin (仮面ライダールパン). However, he is confronted and defeated by Kamen Rider Drive, who burns out Cyberoid ZZZ and forces out Tojo's consciousness, which ends up in a Bat Viral Core.
