Heart

The Heart Roidmude (ハートロイミュード), known simply as Heart (ハート), also known as Roidmude 002 (ロイミュード００２), is the Roidmude responsible for the uprising of the Roidmudes, as well as the deaths of Tenjuro Banno and Krim Steinbelt, although he has a personal revenge against Banno. After Brain's death, he and Medic join forces with the Kamen Riders to stop Banno from summoning the 2nd Global Freeze. Though Banno is defeated, it costs the lives of both Chase and Medic, leaving Heart as the last remaining Roidmude in existence, resolving to settle his conflict in a final battle with Kamen Rider Drive, Shinnosuke Tomari.

Origin
Originally the Roidmude 002, when Banno's research on the Roidmudes hit a dead end, he asked for Krim's help as he gave them the Core Driviars, saving him in the last moment. Later, 002 was forced to copy the appearance of the investor who refused to fund Tenjuro Banno's research. This appearance made him a target to Banno's experiments as he gets his revenge by torturing Heart as if he were the actual investor, but was rescued by Krim Steinbelt, Banno's colleague, whom ceased their partnership after witnessing his insanity. 002 and other two Roidmudes were installed with an evil chip, which not only gave him the negative emotions of human beings but also made him evolve through said emotions. Thus, they killed their creators Banno and Krim (ironically, his rescuer) after their awakening. To ensure that Banno's torture would not be forgotten, 002 retained the human form he had copied.

Global Freeze
During Global Freeze, Heart, alongside numerous other of his Roidmude brethren were defeated by Protodrive. However, Medic, with her unique ability to restore Roidmude bodies, allowed Heart to evolve into the Heart Roidmude where he defeated Kamen Rider Protodrive. From there, he worked together with Freeze and Brain to experiment on Protodrive, stripping him of his memories and free will with the new persona known as Chase.

Drive
He was first seen after Roidmude 029 was defeated by Drive as Heart gives the Roidmude a Viral Core to form a new body.

Heart and Brain were more than content with sitting in the background, though inwardly, Heart fostered a deep rage and grudge against the current Drive when Roidmude Cores were getting destroyed, which reached a fever pitch during Volt's plan, prompted his inclusion into the fight and led to Krim ordering Drive and Kiriko to run immediately upon his appearance. After his near-death experience when saved by Chase before the Dead Zone initiated, Heart weakened slowly with his newly revived comrade, Medic healed him, though the process took some time.

After fully healed, Heart tried to enter the battle again with Chase but Drive quickly called Deco Traveller to delay them, allowing him and the new Rider, Mach to escape. Heart appeared again in his Dead Zone state, overpowering Mach until Drive Type Dead Heat overpowered him and threw him off. After Medic announced that Drive must be annihilated quickly for him having defeated a lot of Roidmudes, all of them (minus Brain) murdered humans that past Roidmudes used as templates for their disguises to lure the Tire Exchange Shift Cars which Medic captured and enslaved. After Heart delayed Mach, Drive was left to face an upgraded Mashin Chaser and the enslaved Shift Cars alone. Mach in the end was forced to lend Shift Dead Heat to Drive at the cost of his own safety.

When Roidmude 089 ("Doctor D") hosted a brief alliance with the remnant terrorist organization, Shocker, as well as from a parallel Earth, Heart congratulated his 'new friend', the Youkai page, on his fruitful gathering of human fear, only for Kyuemon to reject Heart's friendship, referring to the Roidmudes as 'mechanical puppets'. This offended Brain, rebuking by calling him a repulsive monster, with Medic telling 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, Heart was alerted by Brain to a which he saw charging past the window. 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.

With 001's death, Heart was later upgraded by Medic, who granted him the ability of Super Heavy Acceleration.

After weakened Dead Heat Mach as he was about to retrieve the tablet, he was attacked by a revenged Banno.

Heart later achieves the Super Evolution State and reveals his past to Shinnosuke and Go, sparing them when Banno and Roidmude 004 kidnapped Mr. Belt. Heart would later appear to protect Medic against Banno, but ultimately loses Medic due to Brain giving her up and was reprogrammed to absorb excess amounts of energy into her body and warping her freedom.

When Brain "betrays" Heart, Heart is infuriated, shocked that his closest friend would betray him. However, Brain ultimately saves Medic at the cost of losing his own life, causing Heart and Medic to swear vengeance on Banno, only for 004 to allow him to escape as he self-destructs in an attempt to wipe out all of his master's enemies in one single blow.

However, Heart and Medic are saved along with Drive and Chase when Mach takes it upon himself to take the brunt of the shockwave, forcing everyone out of the way. With Banno taking the SSDC as a base to complete the Sigma Circular, Heart and Medic follow the path set by the three Kamen Riders who managed to penetrate Banno's protective barrier. They make their appearance as they save the three immobilized Riders from Banno's killing blow, with Heart giving Go his thanks specifically. Confronting Banno, Heart notes that, having already killed him once, he can give him a fate worse than death by destroying his machine, thus ruining his aspiration to rule humanity. Seeing the prospect of this making Banno visibly uneasy, Heart tells Shinnosuke that they are on the same side now as all five transform to fight Banno and his Reaper Legion Roidmudes. Soon after, Heart and Medic accompany Shinnosuke in heading off to destroy the Sigma Circular, as Go tells him to express his thanks by allowing him to deal with Banno alongside Chase.

After managing to get past the barrier, he, Medic and Drive destroy 081, 101 and 105, but unfortunetly Medic is unable to heal them, leaving him and her as the last of their kind. He tells Shinnosuke they will have their final battle, but not before he learns of Chase's death from Shinnosuke. He and Drive proceed to the Sigma Circular, however Medic is unable to follow them. Medic does show up and manages to heal and injured Shinnosuke, but it does end up using the last of her powers and killing her, much to Heart's anguish. The two manage to destroy the Sigma Circular, however Shinnosuke started to faint as he falls out of the SSDC and ends up being separated from Mr. Belt. Heart attacks Shinnosuke once he regains consciousness and denies the chance to co-exist with humanity. Before he can attack Shinnosuke, Heart's injuries from the final attack on Sigma catch up to him. In the end, he wishes Shinnosuke to remember the Roidmudes as he dies peacefully after at least gaining a new human friend.

Kamen Rider Ghost: Legendary! Riders' Souls!
"And you call yourself a Kamen Rider? The Kamen Rider I knew was a human made of much sterner stuff. Are the two of you really so weak and fragile? Your opposition poses no challenge!"

- Heart unfavorably compares Ghost and Specter to Drive.

Heart is resurrected, appearing in his Super Evolved form, and summoned by Frey following his arrival in the human world at night. Heart proceeds to make his presence known on the following day as he appears out in the open, attacking no-one but gaining the attention of the Kamen Riders' as he waits for them to appear. Makoto Fukami is the first to confront Frey and Heart, warning Takeru Tenkuji that they are not Ganma as he follows accompanied by Akari and Onari. With Takeru and Makoto transforming into Ghost and Specter respectively, Heart recogonizes them as Kamen Riders and thus engages them in battle. Heart is soon enough fought off by the two Riders only to suddenly beat them back with his superior strength. When Ghost and Specter opt to use their respective stronger Eyecons, Toucon Boost and Houdini, Frey robs them of those as well as the rest of their heroic Eyecons, denying them their ability to change Damashii. Continuing his attack on the Riders, Heart unfavorably compares them to Drive only for Ghost to evoke Shinnosuke Tomari as he tells him that humans can always get moving again at top gear. They are subsequently interrupted by the arrival of Freya, who Ghost and the others recognize as similar to Frey as they acknowledge each other. Freya proceeds to provide Kamen Rider Drive's Shift Speed Car for Ghost who unseals the Drive Parka Ghost from it, creating the Drive Ghost Eyecon which he uses to assume Drive Damashii, granting him the power of Kamen Rider Drive and allowing him to turn the tide against and quickly defeat Heart, who is satisfied to feel what he expects from a true Kamen Rider as he is destroyed once again.

Ultimately, it was revealed that Heart and the other past enemies were brought back in order for the Kamen Riders to gather the Kamen Rider Ghost Eyecons so they could defeat the monster Xibalba, as Frey and Freya secretly planned together.

Kamen Rider Drive Saga: Kamen Rider Heart
Two years after the defeat of Banno, Heart has been revived, and with him, the cores of Brain and Medic within him. At the same time, hostile creatures very similar to the Roidmudes appear and start attacking people, specifically the human templates of previous Roidmudes. Heart thinks, "I don't want to witness Roidmudes clinging to a lost past and attacking people". Out of this desire, Heart volunteers to assist Inspector Otta in investigating the attacks. Heart deduces the identity objective of this monster. However, since he is unable to regain his power as a Roidmude, he is at a big disadvantage.

Personality
As his name implies, Heart portrays small empathetic traits like calling Roidmudes his friends and giving destroyed ones new Viral Cores. However, his personality shifts to that of a merciless killer, as seen when killing his creator turned torturer, Banno then ironically his rescuer, Krim Steinbelt. Heart appears to have a grudge against humans, primarily mostly against Drive and Krim to the point where he would activate Dead Zone, a risky move to end the Kamen Rider's life. According to Chase, his reason of hating humanity was because of Banno's abuses on him in 15 years ago.

Heart greatly values his fellow Roidmudes, including Chase, preventing Brain from disposing him after the former realized that he was once a Kamen Rider. After Chase appears to be destroyed, he is overcome with sadness despite Medic telling him that he was disposable and wasn't part of the Promised Number to begin with. After learning Chase was still alive, he took a visit to him. He realized that Chase was lost in finding his way. Despite knowing that Chase might rebel against him again, he told Chase to decide his own way and gave him back the prototype Speed Shift Car. He even sadly bid farewell to Chase after learning that he wanted to return as a Kamen Rider. He soon scolded Medic for destroying her fellow Roidmude who she thought useless when he finally found out the truth of the sudden abnormal decreasing number of his allies.

According to Freeze, Heart's special emotion is "joy", and Heart himself believes that he had already found the key person needed to unlock his evolution, wrongly thinking it to be Chase, and later assuming it to be Drive. His other emotion is "wrath", as Banno is his primary enemy.
