Origin
Roidmude 003 was among the initial trio of Roidmudes created by Tenjuro Banno with aid from his colleague Krim Steinbelt who had provided him with the Core Driviars which allowed him to give them life, with 002 being the first to be activated, having been forced to adopt a human form as Banno abused him out of spite. Bearing witness to 002's pain, Krim condemned Banno's actions and walked out on the project as Banno proceed to install negative human emotions into the Roidmude models, starting with the vacant bodies of 003 and 001.

Vowing that his kind would evolve to surpass Banno and humanity itself, 002, who would become known as Heart, proceeded to overthrow Banno, accompanied by 003 and 001. As a result, the scientist was apparently murdered by his own creations. In reality, however, his digitized consciousness was preserved and contained by the Roidmudes. The three Roidmudes then proceeded to the home of Krim Steinbelt to kill him as well. However, unbeknownst to the Roidmudes, Steinbelt's consciousness was uploaded into the Drive Driver upon his death by their hand.

Global Freeze


"This message goes out to our brethren across the globe. The Kamen Rider... Beware the Kamen Rider!"

- 003 warns the Roidmudes of Protodrive before escaping to cyberspace.

15 years later, all 108 Roidmudes emerged and launched an attack on human civilization which would be known as the Global Freeze. 003 was also the commander and part of the Roidmude onslaught in Tokyo which was stopped by the Shift Cars and Kamen Rider Protodrive. But at the midst of being weakened, he later infiltrated the intelligence agency and knocked out the programming deputy director Mitsuharu Kineta (thus copying his human form), and proceeded with his escaping into the cyberspace to evade Protodrive. Both Brain, Heart, and Freeze (001) acquired Proto-Zero, the defeated Roidmude that sided with Krim Steinbelt and rebooted him (altered his memory as a result) as the Roidmude guardian Mashin Chaser.

Present
Six months later, Brain and Heart remained in Japan to lead Roidmudes stationed in the country. After witnessing Proto-Zero/Protodrive's successor, Shinnosuke Tomari/Drive, Brain became aware of this enemy and for once, poisoned him altough he survived. When Mashin Chaser briefly allowed Drive to save the whole city from Volt Ghost's blackout plan, Brain punished Chase but this unintentionally leads him to discover his number, as well as a small portion of his memories. As Chase and everyone wondered the mystery of the formation of Ride Crosser, Brain revealed that Chase had been Protodrive and finally tried to put an end to him until he was stopped by Heart who let Medic reboot Chase again. Witnessing the rebooted Chase's loyalty as a success, he decided to join in the battle until he was burnt alive by Mach Moerl.

Brain gives the other Roidmude commanders the data of the Special Investigation Unit. Figuring that Drive is among them, he planned to attack and/or expose Drive's civilian identity but all of them sarcastically reject it, rendering him nervous. Witnessing Medic's success had been risen up to the point of correcting Chase's brainwashing and founding the Reaper Legion. Envious of her success, Brain contemplated to find her weaknesses even to the point of sabotaging Chase after his remodeling by Medic via weakening his firewall. Though the strategy was a little success, Medic found out about the whole trick and threatened to eliminate him if he tried to get in her way again.

When Roidmude 089 ("Doctor D") hosted a brief alliance with the remnant terrorist organization, Shocker, as well as from a parallel Earth, Brain took offense at the Youkai page, who rejected Heart's friendship, refering to the Roidmudes as 'mechanical puppets'. Rebuking by calling him a repulsive monster, Medic told Brain to calm himself while Heart noted that from the humans' point of view themselves as Roidmudes would indeed appear to be monsters. Later on, at their hideout, Brain witnessed a charge past the window, to which he alerted Heart. With him and Medic missing the sight, Medic said Brain was being silly again while Heart suggested he get some rest, to which Brain figured that Heart was probably right as the rest of the ' set off to fight Kyuemon's Giant Roidmudes.

After being bested by Medic, he later aligns with Freeze, often calling him as "Teacher", and introduced himself to the police force as Sou Noumi. He later formulated a scheme, by convincing Go Shijima to meet 001 but declined. As he falls to the ground and seemingly to get the upper hand by a desperate Kamen Rider Mach, the Roidmude suddenly took out his iPad, revealing a strange glowing blue screen for Go to see, turning him into the newest part of their faction. In fact, however, Go's memories was altered by 001 to make Go as their trump card in their plans upon to defeat the Kamen Riders, until Go revealed that he is immune to the effect and steals Brain's tablet to rescue his father.

Nira/Thief, with Brain in synchronization targets Yukari Kasawara, one of the eyewitness of Eisuke's death until the Kamen Riders rescue her though they did successfully manage to poison her. He then confronted Medic, telling her to call him Brain-sama before defeating her in his Super Evolved form. Nira and Brain later framed Shinnosuke for trying to take the lead of the Roidmudes and with Special Investigation Unit being backing him up. Though Shinnosuke escapes with the help from his friends, but Nira/Thief faces him instead and nearly gets himself killed by Drive and Chase, had Brain not using his Super Evolve form. Brain left the injured Chase, telling the latter that he would be a part of a bigger plan that the Executives are constructing.

He later joined Nira and Brain in the Special Investigation Unit's office and, after fusing with Nira used a potted plant to demonstrate what he and Nira, as the Thief Roidmude, had done to Yukari, as well as showing that he could kill her instantly if Shinnosuke resisted. After Krim and the Shift Cars had been caught and put in a bag, he separated from Nira and left under his Noumi alias to inform the police that Yukari had been "kidnapped" before entering a tent where six Low-Class Roidmudes joined him in watching Shinnosuke as Yukari's time counted down to zero. However, after Shinnosuke's apparent death, he accidentally revealed his true identity at a press conference about the incident when Yukari, alive and well, walked in saying that the Kamen Riders had saved her. He then fused with Nira, and after Drive Type Tridoron Kouji Genbar managed to separate them, he told Nira that they had never been friends and that he was just a tool for Brain to achieve his Super Evolution before attempting to face all three Riders himself. However, he was ultimately no match for their combined powers, and was defeated by a triple Rider Kick, with his Core being lucky enough to escape. Retreating in embarassment over losing his body, Brain's Core was intercepted by a smug Medic, who promised she would take very good care of him as he begged her to stay away, only for her to play with him much to his dismay.

Due to their mutual disdain of each other, Medic put off restoring Brain's body, leaving him stuck as a Core following her for the time being. In this reduced state, Brain was a witness to Medic's secret experiment with the Cook Roidmude to induce Super Evolution in the Roidmudes, which resulted in several losses. Noting that Heart would not be happy to find out what Medic was doing, Brain later gloated to Medic that she had lost Heart's trust after he revealed his knowledge of her deception, all the while pestering her to restore his body, and his Super Evolution with it, provoking her anger into shutting him up.

Despite his ordeal of being reduced to a Core, Brain's prior achievement of Super Evolution as well as his survival of his body's destruction in battle against the Riders, whereas Freeze before him was eliminated by Drive, made him destined to soon be restored and join the Promised Number, a collection of four Super Evolved Roidmudes, as revealed by Heart when he became the next to achieve Super Evolution.

His body was later restored (through a new Viral Core) by Medic. Roidmude 006 visited both of them delivering his message about Tornado's demise and his possible intention to getting evolved into Super Evolution, leaving only one left to attain it soon.

He is very annoyed when Medic was petting a dog, while patrolling on Misuzu Hatori, whom Special Investigation Unit found and was in contact with the hospital. Until the arrival of a now evil Drive Driver form of Banno, who took control of Medic and tried to kill his own son, but luckily, Heart and Chase arrived to ambush and destroy Banno. A freed Medic told Brain to escape with the dog and split up to get away from Banno. While trying to escape, he spotted and observed 006 battling against Banno, until he is quickly killed by Banno, without destroying the Roidmude's body and Banno then used as a vessel for the mad scientist's manifestation into Kamen Rider Gold Drive. Banno later fought his son, Mach and easily overpowers him, due to inheriting an ability to steal the Riders' weapons and Signal Bikes/Shift Cars. Trying run away from Gold Drive's reign of terror, the dog pees on Brain's foot, causing him to scream with anger, but accidentally causes him to be spotted by Gold Drive for his use.

Heart then confronts Brain asking him where Medic went. Brain reveals that Banno had taken her, causing Heart to get mad. Brain asks for forgiveness, but Heart tells Brain to run so that Banno can never gather the four Promised Number. However, he gave himself in to Banno, which Heart felt livid about. Later after Gold Drive, Heart, Medic, and Brain transfer their energy to the Sigma Circular, the device then proceeds to overload and siphons off its energy to Medic as Banno intended, in order to cause Heart grief. Brain saves Medic by switching places with her using a device that removes the programming which stripped her of her will and made her the target for the siphoned energy. Brain's body cannot handle the energy well, and is engulfed in a giant explosion that affects everyone in the vicinity, both Roidmudes and humans alike. Medic and Heart reach over to Brain in his last moments, holding his hand and grasping onto his leg before he turns to dust with his core disintegrating not long after.

Secret Mission Type TOKUJO
Brain killed and copied Akira Kusakabe, a Superintendent of Tokyo Metropolitan Police Department and used his identity to infiltrate the Special Investigation Unit. However, his purpose was be found and stopped by Shinnosuke Tomari.

Kamen Rider Drive: Final Stage
Brain was revived by Roidmude 108 in the Final Stage. He later turn against Roidmude 108 and gain power from Shift Cars and transformed into Kamen Rider Drive Type Technic.

Super Movie War Genesis
Brain returns alongside Heart and Medic in a black form due to the "butterfly effect" of Shinnosuke Tomari and Takeru Tenkuji time traveling to 2005.

Kamen Rider Heart
Brain and Medic's Cores are reincarnated as part of the revived Heart's body. During the emergence of Roidmude 5886, Brain helped Heart to access the power of Drive. However, because of Brain constantly arguing with Medic, Heart only able to transform into a feeble Drive Type Speed, Wild, Technic. During the second confrontation with 5886, Brain suggests that in order to Unlock Heart true potential as Kamen Rider, he and Medic need to override the Drive Driver system, at the cost of their lives. Heart agreed on this and he transformed into Drive type Miracle. After 5886 was defeated, their core disintegrated. However, before departing to the afterlife, Brain jokingly states that the next time they revived, he'll become the Kamen Rider.

Kamen Rider Build: Be The One
In an event witnessed by Sento Kiryu, Super Evolved Brain was among numerous monsters whom engaged the first 18 Heisei Riders before being wiped out by the Vortex Time Break of Kamen Rider Zi-O BuildArmor.

Kamen Rider Brain
During the events of Kamen Rider Heart, Brain jokingly mentioned that he'll become Kamen Rider next time. However, thanks to the Mu organization searching for someone with a 600 IQ, Brain was fully reconstructed. As the Leader of Mu prepares to erase his memories, a blackout happened and Brain himself was saved by Crystal Peppler, with the former experiencing Deja Vu after seeing Peppler. Brain later found a Driver, tied in his handkerchief out of the blue. As Mu prepare to execute Peppler for his apparent betrayal, Brain transformed into his Super Evolved Roidmude form to fight them to no avail. As Brain fell to his apparent death, he miraculously appeared once more, now transformed into Kamen Rider Brain. As Kamen Rider, Brain manages to defeat most of the Mu members, save for the Leader. Brain later escapes with Peppler on his motorcycle.

Later however, Peppler jokingly reveals that he deliberately chose Brain because he was weak and didn't want to risk making Mu even more powerful, and that rather than a 600 IQ, he has 600 gigabytes of memory. While a stunned Brain absorbs this information, Peppler is kidnapped by Oogumo Great Leader, who runs the professor through with his swords. Before he dies, Peppler reveals to Brain that Mu's ultimate goal is the destruction of individuality, making them exactly the kind of people Brain hates the most, and explaining that this was the real reason he chose Brain to become a Rider. Motivated by his friend's death, Brain transforms and defeats Mu's Dark Riders and Oogumo Great Leader before returning to the laboratory to confront the Leader of Mu. However, at this point Brain wakes up in a white datascape with Heart and Medic, revealing that these events were just a dream Brain was having while the Executive Roidmudes' data was being compiled sometime after the events of Kamen Rider Heart.

Personality
As his name suggests, Brain acted as the tactical leader of the team. He seemed to be the type that is of the "insufferable genius", as he is easily irritated, like how most of the evolved Roidmudes are, to him, those with a "rude" personality, preferring those that are loyal and wise like him. Aside from his cold personality, he is also calculative, as shown he could simply drip a venomous neurotoxin which powerful enough to kill Drive, had he not been using the Mad Doctor Shift Car. He also has shown signs of being somewhat sadistic, if his laughter when pitting Mach against Drive and Chaser was any indication. Of course, this is similar to his human synch, Mitsuhide Nira due to both having huge jealousy for their rivals.

Brain often puts three adjective-words for making descriptions.

"I must redeem myself by any means necessary! How dare there be someone more useful to Heart than me?! Curse you Medic!"

- Brain gets nervous.

Ironically, despite his brain motif and cool headed outlook, he can easily become nervous whenever someone (particularly Medic) does a better job than him. This is displayed in several occasions, for example when Medic did a better job at reprogramming Chase by altering a portion of his base program, thus earning Heart's respect. This results in Brain developing a sense of jealousy towards Medic, and constantly trying to find flaws in her personality in order to redeem himself and regain his comrade's respect. Brain also has a habit of taking out his handkerchief whenever he becomes nervous. It is implied that he treasures his possessions a lot, and losing them would severely affected his emotions. During the events when he sided with Gold Drive to manipulate Medic and caused her to become his puppet, Brain becomes troubled by his sense of guilt, especially when Heart was the person whose mostly affected by this. Combined with his determination to save Medic, Brain proved his devotion to Heart by sacrificing himself to save her, at the same time redeeming himself. Heart and Medic were heartbroken from this, while the Kamen Riders (including Go himself) became disgusted at Banno for causing Brain's death.

According to Freeze, Brain's special emotion is "envy".

In Kamen Rider Drive Saga: Kamen Rider Brain, Brain has shown a significant difference in personality. No longer showing signs of malice as he had previously done, Brain even became joyous at being a Kamen Rider in his dream, to the point of cheerfully telling Heart and Medic as they were being revived by Go Shijima/Kamen Rider Mach. .

In an April Fools' joke for 2017, the official Kamen Rider Drive Twitter announced a V-Cinema "Drive Saga: Kamen Rider Brain" (ドライブサーガ: 仮面ライダーブレン) which will be released in 2035, throwing back to Brain's line about being the next to become a Kamen Rider at the end of Kamen Rider Heart.
