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 Dr. Banno and Krim Steinbelt.

Character History
He was one of the first Roidmudes to be created by his inventor, Dr. Banno, 15 years prior to the series, who then rebelled and killed his inventor and Krim Steinbelt, with the latter surviving by uploading his conscious into the Drive Driver, making it his new body. Later, Heart would evolve into his present form and overwhelmed and then defeated Protodrive. Discovering Protodrive was the Roidmude Proto-Zero, he ordered Brain to reboot him as the Roidmude guardian, Mashin Chaser. Heart also confiscated Protodrive's sole Shift Car, the Shift Speed Prototype, which he would keep on his person.

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

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 both Krim Steinbelt and his creator, Banno. Heart appears to have a grudge against humans, primarily mostly against Drive and Krim Steinbelt to the point where he would activate Dead Zone, a risky move to end the Kamen Rider's life.

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.
