He would later transform into .
==History==
===Background===
Heart, originally designated as Roidmude 002, was among the first Roidmudes produced by Dr. Tenjuro Banno. When development for the Roidmudes hit a dead end, Krim Steinbelt provided Banno with the Core Driviars, enabling the Roidmudes to have the capacity to evolve. 002 was later forced to take on the appearance of Shinzo Hiroi, an investor who once refused to fund Banno's research, and endured severe torturing from his creator as if he were actually Hiroi. While Krim Steinbelt rescued him at the last second, he ceased his partnership with Banno after witnessing his insanity. 002 and the other two Roidmudes were installed with an evil chip, which gave him the negative emotions like humans and made him evolve through said emotions. Thus, they killed their creators Banno and Krim after their awakening. Heart also retained the human form he had copied to ensure that Banno's abuse would not be forgotten.
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.
===The Roidmude Leader===
Six months following the Global Freeze, Heart and the Roidmudes resurfaced again to start another revolution against humanity. Along with Brain in his side, Heart sought to evolve more of his kind into Advanced Roidmudes. However, they encountered a new foe named, Shinnosuke Tomari, a police investigator for the Special Investigation Unit and the latest incarnation of Kamen Rider Drive. Though they suffered several setbacks because of Drive, Heart began to foster a deep grudge against his advesary as many Roidmude Cores were getting destroyed.
Heart remained a formidable opponent towards Drive due to his Dead Zone technique that proved to be powerful, yet deadly to him. Although he was saved by Mashin Chaser, he suffered great damage due to the influence of the Dead Zone, and after that he decided to concentrate on recovery. Thanks to the actions of the Volt Roidmude, Heart and the Roidmudes were eventually able to reawaken Medic, who had gone comatose due to the strain of healing other Roidmudes, adding a key member into their ranks.
===Advancing The Battle===
While Medic's resurgence allowed Heart's recovery process to proceed quickly, another issue arose when Chase regained his memories as Protozero. With the arrival of Kamen Rider Mach, the Kamen Riders manage to gain access to a new form called Type Dead Heat to combat against Heart's Dead Zone. Upon making a full recovery, he prepared for another battle against Drive, but overwhelmed by the Type Dead Heat. While he didn't feel sad that he lost, but rather felt "joyful" that his rival became stronger.
Heart recognized Chase has been unable to operate as the "grim reaper" and eliminating any rogue Roidmudes. He did in fact care for Chase, even displaying sadness when he learnt of his death. Upon learning that his friend was alive, Heart went out of his way to engage Drive to bring him back. While realizing Chase's conflicted feelings, he returned the Shift Prototype Speed and encouraged him to figure out his own path. Despite Chase opting to side with humanity as Kamen Rider Chaser, Heart accepted the fact and still considered to him as a friend regardless.
===The Ultimate Evolution===
Eventually, Heart would reunite with Freeze as his comrade had unveiled the Neo-Viral Cores to make Roidmude evolution easier by having the Low-Class Roidmudes fuse with humans. Heart becomes elated by the prospect of being one step closer to achieving the Promised Number, especially when all he needed to do was to amplify his chosen emotion of "joy". While Freeze would eventually become the first Roidmude to achieve a Over Evolved state, he was killed shortly after by Drive Type Tridoron.
Heart was later upgraded by Medic, who granted him the ability of Super Heavy Acceleration. While still scouting for more Roidmudes capable of reaching the Over Evolved state, he learnt of Medic's experiments of forcibly inducing the ultimate evolution onto their brethren. While he was visably angered at her for this treachery, Heart eventually forgave Medic after telling her she didn't need to sacrifice their own kind to evolve quickly. Having respecting the pride of being Shinnosuke Tomari's rival, Heart empowered himself with happiness and receives his own Over Evolved State.
===The Promised Number===
Soon, more Roidmude executives from all over Earth return to Japan in the race to achieve the Over Evolved state with the additional task to all re-capture and destroy Banno, who is currently in Go's possession. While the Over Evolved Heart was engaging Drive and Mach, the entire battlefield was blown away when Banno suddenly attacked the area. The three managed to retreat to the forest where Heart confided to Shinnosuke and Go about his horrible past and experience with Banno, with him even expressing sympathy towards Go realizing his father wasn't a good person.
Heart would eventually reunite with Banno, having become Gold Drive and possessed a similar Over Evolved state like him. But Heart refused to trust him because of the aforementioned trauma. He was distrustful towards his creator, especially when he discovered that he had brainwashed Medic to his side once she recieved her own Over Evolved state. While he is blackmailed by Banno into serving him, he tries to warn Brain to leave town while he still has a chance.
When Brain returns to seemingly help Banno in his plans to awaken the Sigma Circular, Heart felt livid 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 break down in saddness and swear vengeance on Banno. Heart and Medic joins the Kamen Riders in the SSDC Building where Banno plans to enact his second Global Freeze, with Heart noting that he would rather give him a fate worse than death by destroying his machine, thus ruining his aspiration to rule humanity.
Heart fought alongside Drive and Medic in order to deal with the Sigma Circular, while Mach and Chase dealt with Gold Drive. While Heart was forced to defeat the remaining Roidmude Reapers, he was saddened when he learnt of Chase's demise and realizing that he and Medic are the last remaining Roidmudes. They all proceed to the Sigma Circular, except for Medic, who is unable to follow them. Medic does show up to heal an injured Shinnosuke. This uses up the last of her powers and ends her life, much to Heart's anguish. However, this allows an empowered Drive Type Tridoron and Over Evolved Heart to vanquish the Sigma Circular once and for all, foiling the second Global Freeze.
===Final Battle and Death===
After Heart and Drive manage to destroy the Sigma Circular, Shinnosuke started to faint as he falls out of the SSDC building, only to be rescued by Heart at the nick of time. Heart attacks his rival 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 catches up to him. While admitting defeat, he wishes Shinnosuke to remember the Roidmudes as he dies peacefully after at least gaining a new human friend.

===Kamen Rider Revice: The Mystery===
==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. Though caring for Roidmudes in general, it is clear that Heart values Brain, Chase, and Medic the most, showing great sadness when each had died against Banno and his forces. 
Though having wished for the Roidmude race to rise above humanity, Heart did not have a condescending attitude towards humans like most Roidmudes did. Indeed, Heart has recognized Shinnosuke Tomari/Kamen Rider Drive as a worthy adversary, noting his courage and tenacity. Near his initial death, Heart even learned to overcome his hatred towards humans, befriending Shinnosuke before his core was destroyed. Since then, Heart has shown respect for humanity, especially those who carry the mantle of "Kamen Rider". This change of heart would later prove beneficial for Heart, allowing him to befriend Genpachiro Otta, as well as be chosen by Go Shijima/Kamen Rider Mach to be revived alongside Brain, Chase, and Medic.
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.
