Extra-terrestrial Lifeform Evolto (地球外生命体・エボルト, Chikyūgai Seimeitai Eboruto), alternately spelt Evolt[1], is the main antagonist of Kamen Rider Build. He is a member of the Blood Tribe who manipulated the Pandora Box to annihilate the civilization of Mars. After possessing the body of Soichi Isurugi, he instigated the Japanese Civil War by causing the Sky Wall Disaster, which resulted in the creation of Faust. He operated as one of their agents by using the Transteam Gun to transform into Blood Stalk, until he regained his lost Evol-Driver during the war to transform into Kamen Rider Evol.

History

Background

Evolto during Planet Blood's destruction

Long ago, Evolto was born on Planet Blood as the younger brother of the ruler, Killbus. Sometime during Evolto's adulthood, his brother destroyed the planet, but not before Evolto and a few others escaped with the Pandora Box. Since then, they've gone on to destroy countless other planets before setting their sights on Mars.

Evolto fights Vernage on Mars.

Not much is known about how Evolto and the Blood Tribe began their attack on Mars, but the fact is that he used the Pandora Box to raise the Pandora Tower on Mars, ravaging the planet with a black hole. However, his body and Evol-Driver was destroyed after the final battle with the Martian Queen Vernage. However, Evolto's soul stored itself within the Pandora Box, preserving his essence and energy, albeit fragmented.

Twenty-three years ago, a space probe from Earth arrived on Mars and a part of Evolto's essence attached itself onto the spacecraft in search of the next planet to destroy. When the probe returned on Earth, Evolto's essence attempted to possess the security guard, Yuri Banjo. However, the essence assimilated with Banjo's unborn son. The child, Ryuga Banjo, was born a month later and shared Evolto's essence but none of his consciousness nor abilities.

Approximately thirteen years later, Evolto came into contact with the astronaut Soichi Isurugi, who was on a manned mission to Mars, and took over his body once he touched the Pandora Box in the Martian ruins. Creating sixty Fullbottles from Isurugi's memories, Evolto arrived on Earth and attempted to raise the Pandora Tower using the Pandora Box during the return ceremony. However, his attempt failed as Vernage also found her way to Earth and removed the essence of the Fullbottles, causing the Sky Wall to rise instead. After that, although he was forcibly taken to the mental hospital, Evolto managed to escape. The Evolto-possessed Soichi made contact with Shinobu Katsuragi and threatened him to repair his Evol-Driver and create a new set of Fullbottles.

In the following seven years, the Evolto-possessed Isurugi introduced himself to Gentoku Himuro and Takumi Katsuragi so he could provide his assistance with their Nebula Gas experiments, as they formed their organization Faust to use Nebula Gas technology to benefit the country. It was also around this time when Misora was forced to purify the Fullbottles for Faust. Sometime after, Evolto received a Transteam Gun and a Cobra Fullbottle, allowing him to become Blood Stalk.

Eventually, Takumi Katsuragi discovered Blood Stalk's extraterrestrial identity as Evolto and threatened to quit Faust and expose their modus operandi. However, Evolto knocked him out and erased his memories, also switching his face with Taro Satou after he had unexpectedly arrived. He later called the authorities to arrest Ryuga once he arrived as the fall guy to Katsuragi's supposed murder. Recognizing Katsuragi's intelligence could be some use to him, Evolto arranged for an amnesiac Katsuragi to be lost in the alleyway during a rainy day and meeting Soichi Isurugi, who took him in and gave him the name "Sento Kiryu". Evolto as Isurugi indoctrinated both Sento and Misora to fighting Smashes and harvesting their Nebula Gas essence into Fullbottles.

Observing Sento Kiryu

One year after Sento Kiryu became Kamen Rider Build, Isurugi meets up with Sento if he still remembers his past, but Sento struggles to make out the fragments of his past. Deciding to charge him for rent, Isurugi made Sento take the job position at Touto's Institute of Advanced Matter Physics. Isurugi later informs Sento about Ryuga Banjo and sends him to go meet up with the escaped convict. Sento learned that Ryuga was also experimented and believed he could be innocent for the murder of Takumi Katsuragi. Since then, Isurugi remained on the sidelines with Build's activities giving both Sento and Ryuga guidance with the battles against the Smash and imparted wisdom at times.

The group becomes aware that Masahiro Nabeshima has a connection to Takumi Katsuragi's murder and Ryuga's jailbreak. After fighting the Flying Smash in town, Sento and Ryuga smuggle themselves into Seito and found Nabeshima having turned into the Mirage Smash. Although Build purified Nabeshima, Blood Stalk neutralizes him and falls unconscious. He later finds himself waking up in his lab, with Soichi apparently saving him from the encounter. After Nabeshima was re-purified by Sento after turned into a Smash a second time, he would clue Sento about the Pandora Panel in the lab's wall, the same one that Faust had.

Sento confronted Isurugi about the Panel and gave the explanation that he was a former Faust member, but left after the organization exploited Misora's ability to purify bottles. Isurugi also laughed at the prospect that if he was a villain, he wouldn't be so "stylish". When Sento decided to continue looking up information regarding his own memories, Isurugi decided to reintroduce himself to the amnesiac scientist as Blood Stalk, another executive member of Faust.

As an high-ranking executive of Faust, Evolto as Blood Stalk participating in abducting several individuals to be experimented with Nebula Gas. Blood Stalk would come into conflict with his accomplice Night Rogue, as the former would often let Build and Ryuga Banjo escape. Although Stalk claims that he has bigger plans for the both of them, Gentoku struggled to continue trusting him. While he made his presence, Blood Stalk would often be mistaken of being Takumi Katsuragi, but would never confirmed or deny that fact when questioned.

After Gentoku's private meeting with one of Faust's investors, Juzaburo Namba, Stalk noticed Gentoku had become increasingly desperate to distribute the Rider System. Stalk participates in Gentoku's plan seize the Pandora Box from the Touto Institute. When Stalk raided the Touto Institute, he shut down the security cameras after confronting the three Prime Ministers. Gentoku later arrives to confronted Stalk and demands him to hand over the Pandora Box. Night Rogue engages Blood Stalk, only to be interrupted by the arrival of Build and Ryuga Banjo. However, Rogue manages to best Build in battle and take all of his Fullbottles. Stalk assured him that he will bring the Pandora Box back to Faust.

After Gentoku became the acting Prime Minister of Touto, Stalk congratulated him for his new position and asks where he had hidden Pandora Box, only for Gentoku to keep silent as he did not fully trust Stalk. When Night Rogue flushed out Sento and Ryuga in a false Smash alert to force them to hand over the remaining Fullbottles, but Stalk later lets them get away.

Sometime after Ryuga became Kamen Rider Cross-Z, Sento and Ryuga storm into Namba Heavy Industries' science laboratory to find the location of the Pandora Box. While Night Rogue tries to stop them, Blood Stalk arrives to protect them. While Stalk engages Night Rogue again, Sento and Ryuga managed to reclaim their Fullbottles and even new Fullbottles in Faust's possession. Stalk also leaves with the Pandora Box, infuriating Rogue.

In the woods, Stalk meets up with Gentoku who demanded the Pandora Box. Stalk agreed in exchange for Gentoku's loyalty. Fed up, Gentoku transforms into Night Rogue, but Stalk doubts Rogue can beat him. Rogue seemingly gained the upper hand on Stalk, until he realizes Stalk's been holding back due to having more experience with the Transteam System than Rogue and overpowers him. Before leaving, Stalk confirms to Gentoku that he has partnered up with Namba, meaning the Pandora Box is in Namba Heavy Industries, making it complicated to infiltrate unnoticed. This led Gentoku to confide with Sento the Pandora Box's location, just so he can have Sento and Ryuga retrieve the relic for him.

One night, Sento received a phone call from Nabeshima who regained his memories and disclosed Stalk's true identity as Soichi Isurugi. While Sento was suspicious with the revelation, he decided to put Nabeshima's claims to test by claiming to the rest of his teammates that Katsuragi is indeed Blood Stalk and enacting a secret strategy that allowed Build to defeat Stalk in battle. During the night after Sento retrieved the Pandora Box from Faust, he catches Isurugi trying leaving with the relic and a collection of Fullbottles, which confirmed Sento's suspicions that the man who found him that rainy day was indeed his enemy.

Evolto, as "Soichi" about to transform into Blood Stalk

Sento chased him down and engaged Blood Stalk as Build, but found himself defeated after Isurugi used the Pandora Box's powers. Upon learning of Isurugi's true past of being recruited to Faust sometime after he caused the Sky Wall Disaster, Sento would confront Isurugi in the same spot where he first met him, with the latter claiming Sento and Ryuga were "pawns" in his games. Although he did hesitate on fighting that man who raised him, Sento managed to overcome his battle by using RabbitTank Sparkling Fullbottle, created from the energies of the Pandora Box, to defeat Blood Stalk. As Stalk retreated, he informed Sento that Gentoku Himuro is actually Night Rogue.

Isurugi, as Blood Stalk, watches from the shadows as Sento and Ryuga confronted Gentoku as Night Rogue. After tricking Sento into researching Katsuragi's Sclash Driver System, Isurugi entered the lab to copy the data. He found himself confronted by Misora, shocked by her "father"'s betrayal.

As Gentoku was being handed over by the authorities due to his cover as Night Rogue was blown, he revealed to Sento that that the amnesiac scientist is actually Takumi Katsuragi the entire time. Gentoku confirmed that Takumi Katsuragi had his memories erased by Blood Stalk and changed his appearance to resemble Taro Satou, hence "Sento Kiryu" was born. After his alliance with Touto served his purpose, he later poisoned Taizan Himuro to keep Gentoku's secret identity. Within the next few days, Stalk stood in Prime Minister Tajimi's office while she led Hokuto's invasion, with Faust forming an alliance with Hokuto in the second phase of his overall scheme. Stalk as the war for the Pandora Box had begun.

The Japanese Civil War

As new Hazard Smash were starting to surface following Faust's apparent dissolution, the starving nation of Hokuto declared war on Touto by sending an army of forces to secure the Pandora Box. Blood Stalk relocated Faust to Hokuto as he aligned with Prime Minister Tajimi to invade Touto. Through his partnership with Namba Heavy Industries, Stalk managed to produce the Sclash Driver and Hazard Smash, even paving way for the creation of Kamen Rider Grease and the Hard Smash.

As Build and Cross-Z Change fought against Grease and the Hokuto Sanbagarasu, Stalk arrived and announced Sento's Hazard Level had become lower than expected. Knowing that Sento and Ryuga can't defeat Grease and the Hokuto Sanbagarasu, Sento would question what his true motives are, with Isurugi reminded him all he wants is to see Sento and Ryuga grow as Kamen Riders and he looks forward to it. Noticing how far Sento is falling far behind, Stalk would later gift him the Hazard Trigger, a forbidden item created by Katsuragi that would evolve Build into the Hazard Forms.

When Sento started using the Hazard Trigger, the item's effect took hold and sent Sento into a mindless rage, causing him to accidentally kill Aoba. Isurugi met with a depressed Sento, who was in a downward depression over the murder he recently committed. he remarks how Sento would've fought in the war without hurting anyone and even optimism has limits. Isurugi tries convince an unmotivated Sento to participate in the proxy battle between Touto and Hokuto, even leaving him the Hokuto and Seito Fullbottles in the possession. Blood Stalk later trains with Sento in using the Best Matches as the latter prepares for his duel with Grease.

As the proxy battle between Build and Grease came underway, Blood Stalk stood beside Tajimi in the Hokuto capital as they watched the proxy fight on television. It is revealed that even if Grease loses, Hokuto will still continue invading Touto. After Grease was defeated by Build using the Hazard Trigger, Stalk stops Tajimi from giving the order as Seito Guardians storm the building and reveals that he was never on Hokuto's side. As the Seito Guardians apprehend Tajimi, Stalk is elated to see Seito's representative Kamen Rider enter the room.

It was revealed that Blood Stalk had been aligned with Seito from behind the scenes. He and Namba Heavy Industries had struck a deal with Masakuni Mido and the Seito government and have move Faust's base of operations there. After reuniting with his former accomplice Gentoku Hiromu, who had been exiled from Touto, Stalk had watched his Gentoku's progression as Kamen Rider Rogue as he witnessed the pain and torture it took for him to achieve such power.

After Stalk discovered Vernage had reawakened inside of Misora, he met with Sento and acknowledged that he is gonna try to avoid his "daughter" from now on. The Evolto-possessed Isurugi dropped information regarding the Namba Children and how Juzaburo Namba indoctrinated several children to become his personal spies, cluing Sento to figure out Sawa Takigawa's true origins as one of the Namba Children.

After the proxy battle between Touto and Seito ended with victory for Touto, Blood Stalk was summoned by Namba to kill Seito Prime Minister Mido when he refused to dishonor his promise to relinquish his claim to the Fullbottles and the Pandora Box. Blood Stalk then used his power to modify Namba's face into that of the late Prime Minister, allowing him to personally take control of Seito and launch his own invasion of Touto using the full arsenal provided by Namba Heavy Industries.

The Evolto Revolution

Although the war between Touto and Seito had come to a close with the proxy battle, Blood Stalk decided to press on used the completed Pandora Box to transfigure Sky Wall into the Pandora Tower after inserting the Fullbottles into the Panels. Heading to the surface, Stalk arrived where Build, Cross-Z Charge, and Grease engage against newly built Hard Guardians. Stalk praised the Power Tower and with its completion will mean the destruction of Earth like with Mars. When the Kamen Riders arrived to the Seito border to claim the Pandora Box, Stalk led the Washio Bros and a couple of Hard Guardians to the Touto-Hokuto border and combatted Build, Cross-Z Charge, and Grease.

When Rai Washio capture Misora and held her hostage, Vernage had awakened with her. This irritated Stalk and he tried to shoot her with his Transteam Gun, only to push him aside out of transformation. Realizing her strength, Evolto tries to fire an energy blast at her, only to be shielded by Cross-Z and damaging Ryuga's Sclash Driver and the Dragon Sclashjelly. Vernage transported the Kamen Riders away and would inform them of Blood Stalk's true nature as "Evolto". The real Isurugi, still conscious within his body, questions Evolto's true intentions, only for the alien to brush him aside as he continues to control his body.

"Finally, the vessel is complete. Now I just need to find the ultimate driver, and everything will be in place."
―A defeated Blood Stalk now satisfied with Cross-Z's new power.[src]

Once the Kamen Riders stormed into the Pandora Tower, Blood Stalk arrives to create a new battlefield using the Pandora Box. After Build, Cross-Z, and Grease got past Seito's forces, Stalk greeted them and creates Smash clones for them to fight. Ryuga confronts Stalk over the revelation how he organized Kazumi's transformation into a Smash. After defeating Ryuga and setting his sights on Sento, Ryuga's anger became stronger which finally stabilized the Dragon Magma Fullbottle. Ryuga used the Cross-Z Magma Knuckle and the Dragon Magma Fullbottle to transform into Cross-Z Magma. His new form was able to knock down Stalk and give him the chance to take Pandora Box as well as save the others. However, this elates Stalk as he found the perfect vessel in Ryuga and everything in his plans will fall into place.

Ryuga would eventually discover his connection with Evolto. Although this devastated Ryuga to question the humanity he had left, Ryuga became determined to use his power as a Kamen Rider to fight for love and peace, the very same ideal that Sento believes in and strongly holds onto. Stalk led a raid with Seito's forces to attack Touto and combat the Kamen Riders, only to distract them as Gentoku captures Touto Prime Minister Himuro.

"I...I finally have it again!"
―Evolto rejoicing in reuniting with the Evol-Driver[src]

Evolto offered the Kamen Riders the chance to return the Touto Prime Minister's life in exchange for the Evol-Driver, that was previously hidden by Takumi Katsuragi. Sento, aware the risk of returning the belt to Evolto, manages to restore it and meets up with Stalk at the exchange point. After Stalk wouldn't cooperate with the Sento demands, the Kamen Riders managed to secure Taizan with Rogue's help. Stalk continued to pursue retrieving back the Evol-Driver. With Utsumi's help, Evolto regained his lost belt and transforms into Kamen Rider Evol Cobra, which he dubbed "Phase 1". With no opportune moment, Evol took down Rogue without any effort and as he laid for the killing blow, Taizan sacrifices his life to save his son from harms way, much to Gentoku's distraught and grief.

When Build, Cross-Z, and Grease arrived battle with Kamen Rider Evol, Evolto manages to take all three of them down. Evol later poisons Sento and claims he has only three days left to live and can be saved if he is handed the Pandora Box. Needing the antidote to save him, Ryuga confronts Evolto. Evolto revealed the truth behind Ryuga's framing for Takumi Katsuragi's "murder" and explained how Katsuragi planned on luring Ryuga in his apartment to destroy him as he posed a threat carrying Evolto's genes. Ryuga was in disbelief on what Katsuragi intended to do before becoming Sento, but continued on to cure Sento from the poison by defeating Evol in order to save his friend. However, Evolto takes this opportunity to possess Ryuga and can access Evol's Dragon-based Phase 2 form.

Evolto having possessed Ryuga as Evol Phase 2.

As Evolto-possessed Ryuga takes the Pandora Box to continue raising the Pandora Tower, Build joined with Grease and Rogue to battle with Evol. Sento restores to using Hazard Best Matches to battle Evolto, before using the FullFull RabbitTank bottle to assume TankTank Form. While Evol begins to tell Build that science is the key to humanity's destruction, but Build retorts that people aren't so simple to easily allow destruction to happen as they have the power to prevent it in the first place. After using underhanded tricks to overpower Build, he allows Sento to bear witness the Pandora Tower being completed as the Earth's destruction is now imminent.

However, Evolto ceases his destruction due to the Evol Trigger still being incomplete. The Vernage-possessed Misora appears and teleports herself, Sento, and Pandora's Box back to Nascita. In an effort to stop Evolto from reaching his true final form, Sento researches one of the Pandora Panels in order to engineer Build's final power-up, despite the risk to his life when using it. Once called out to battle with Grease, Build challenged Evol and used the power of the Pandora Panel. When Evolto tried to take advantage of the situation and separated Ryuga from his influence, Sento managed to further increase his Hazard Level intending to sacrifice himself to destroy Evolto. After the two exploded, it left only a white-haired Sento standing, as Evolto managed to take over Sento's body.

Evolto having possessed Sento as Evol Phase 3.

With Sento now in Evolto's possession, Evolto creates the Rabbit Evolbottle and can access Evol's Rabbit-based Phase 3 form. But Evolto still fails to activate the Evol Trigger, believing humans aren't strong enough to handle the power of Pandora Box. He also uses the Pandora Box's power to create a Black Pandora Panel. Ryuga had lost his ability to transform ever since they separated, with none of Evolto's essence left in him. While Grease and Rogue engaged the Evol, Ryuga found the strength enough to raise what was left of Evolt in his genes to become Great Cross-Z. However, Evolto manages to complete the Evol Trigger from the Kamen Riders' powers, allowing him to achieve his complete form, Black Hole Form.

Evolto, now in his completed form, Phase 4: Black Hole.

"Phase 4 complete. Thanks to you, I'm complete again."
―Evolto thanking Banjo and the reawakened Katsuragi.[src]

Sento is jettisoned from Evolto, but his memories of Takumi Katsuragi resurfaces, while his memories of being Sento are now gone. Landing back on the first floor, Evol thanked both Katsuragi and Ryuga for their roles in helping him regain his true form until Grease and Rogue caught up to Evol, but he pushes them both away with his new strength. After he retreating back to Namba Heavy Industries, Evolto demonstrated his ability to shapeshift to Juzaburo Namba. As Namba Heavy Industries' alliance with Evolto was waning, the Kamen Riders formed an alliance with them to take Evolto down. However, even with combined forces, Evolto in his complete form was still invincible and managed to kill the Washio brothers during their battle. After teleporting himself to meet with Namba, he killed him over his betrayal. Evolto also recruited Nariaki Utsumi to join him as his assistant, giving him the Evol-Driver to become Kamen Rider MadRogue.

Without Namba assuming his disguise as Masakuni Mido, Evolto resumed the facade of the Seito Prime Minister himself as he commanded Seito's forces to attack Touto. Evolto began to collect the Faust Fullbottles. Evol watched as Utsumi led a squad of Hard Guardians mount an attack on the Touto capital to draw out the Kamen Riders, which Great Cross-Z and Grease came to stop them. Later on, Katsuragi came to fight MadRogue. During the fight, Evol witnessed Katsuragi restored back to Sento Kiryu and transformed into Kamen Rider Build Genius.

Quest of the Lost Bottles

Evol watched as Build Genius overpowered MadRogue with his new powers and defeated him. Seeing enough, Evol teleported to the capital and commended Build for concealing such a weapon that could rival Evol's power. As Build prepared to fight, Evol assured him they will in time as he swiped the Hokuto Sanbagarasu's Fullbottles from Kazumi's possession, which are dubbed "Lost Bottles". When Sento and Kazumi arrived in Hokuto to research Shinobu Katsuragi's connections with the Lost Bottles, Evol meets up with them as he is amazed Sento is capable of using the Genius Fullbottle to save a Lost Smash.

"I blocked it perfectly...Why?! What is this emotion?! How could I have been beaten by an inferior lifeform like you?!"
―An enraged Evol refused to accept being bested by a human as he ferociously attacks Build.[src]

Sento fought Evol as Build Genius and defeated him using hyperspeed. Before Evol could even use the Evol Trigger, Build Genius stopped him and managed to land a blow on his chest. This caused Evolto to receive an influx of emotions bestowed upon him by Build's attack. Rising to his feet, Evolto praises Build for his ingenuity with the Genius Fullbottle's power. Later, Evol encounters Sento again after he saved Kyoichi Shimizu in order to turn him into a Lost Smash. However, Build Genius' powers were able to neutralize the Lost Bottle's effects as Sento declared he'll build back everything whatever Evolto destroys. This causes Evolto to feel emotions of rage, causing him to senselessly attack Sento before he retreated.

Evolto with Shinobu Katsuragi as he reveals to Sento.

Eventually, it is revealed that Sento's biological father, Shinobu Katsuragi, is alive and is working with Evolto from the shadows. Evolto begins to declare his intentions to rule the country, even destroying the Touto capital building with one of his black holes. Returning to Seito, Evolto shapeshifted into Mido and made a broadcast to all of Japan, stating the civil war is now over and the three segments of the country are now one once more.

Evolto's apparent defeat against the four Kamen Riders.

With three Lost Bottles remaining, Evolto gradually began to feel distrust of Shinobu, who continues to fail in capturing the Kamen Riders, but the latter claims the he still desired to "open the door to the new world". After Vernage was transferred to Ryuga, it paved way for the creation of the Blizzard Knuckle. Although Sento decided to confront Evolto for the final Lost Bottle, he was joined with Ryuga, Kazumi, and Gentoku and the four transformed into Build, Cross-Z, Grease, and Rogue. The quartet fought Evolt, with Sento affirming their teamwork will turn the tides, with the others immobilizing Evolto in his place and allowing Build to use his Genius Finish and defeat Evolto.

While Evolto was seemingly vanquished, Shinobu arrived with a large container to place the Evol-Driver inside it as it had Evolto's remaining genes. Shinobu revealed Evolto's regeneration ability and how he had been fighting against the alien invader to eliminate him from evolving using the Black Panel. Evolto resurfaced after slipping his essence into Utsumi and expecting Shinobu's ploy, he poisoned him to his death. As the Kamen Riders escape, Evolto manages to retrieve the Black Panel and would able able to complete it with the final Lost Bottle. This allowed him to evolve into a horrifying new monster form now with the ability to warp to different planets. As Evolto then voiced his intent to destroy Earth next, Sento decided to use the Genius Bottle in conjunction with the Hazard Trigger to purify a couple of Lost Bottles and restore Evolto back to Evol Black Hole.

As a plan to eliminate Evolto once and for all, Sento formulated a plan to create the White Pandora Panel and use it with the Black Panel to summon an alternate world without Sky Wall and merge it with the current Earth, using Evolto as a catalyst to connect the two worlds. Once Evolto finally revealed his true colors and his intent to destroy the Earth publicly on live television, the Kamen Riders would arrive the next day in front of the Pandora Tower to challenge Evolto and his army of Hard Guardians, they climbed up to the tower and are ambushed by his replicants.

When he noticed Utsumi had finally sided with the Kamen Riders, Evolto meets up with MadRogue as Rogue was with him. However, Utsumi was able to overwhelm Evol in battle with the Evol-Driver's full potential, only to see him short-circuit. It was revealed Evolto turned Utsumi into a cyborg after Gentoku shot him, making a distraught Rogue charging in but knocked aside by Evol. After Utsumi saved him at the last minute, Gentoku teleported himself and Sawa elsewhere with the Nebulasteam Gun. Upon arriving on top of the Pandora Tower, with the Nascita team distraught over the loss of Kazumi Sawatari, Evolto greeted them with a light-hearted greeting.

Sento, Ryuga and Gentoku transform into Build Genius, Cross-Z Magma, and Rogue to charge at Evolto, with Build Genius matching Evolto in speed. As the three Riders were down, Evolto becomes unimpressed by the performance they've shown. When Build accidentally drops the Lost Bottles, it allowed Evolto to regain his monster form and evolved by his Evol Trigger's Feverflow. While Rogue continues to fight Evolto, Gentoku managed to sacrifice himself in order to immobilize Evolto with the Evol-Trigger, allowing Build to extract the Black Panel out of him. With the Black and White Panels in hand, Sento succeeds in using them to summon another Earth and trapping Evolto to tether the worlds. However at the last second, Evolto manages to capture Ryuga while he was sent away in the ripple between the two Earths.

Final Battle And Demise

"You? destroy me? I cannot let that happen, you worthless humans!"
―Evolto's final words before his death.[src]

The death of Evolto.

Evolto was sent to the ripple between the Earth he previously inhabited and the alternate Earth without Sky Wall. Anticipating Build would arrive rescue Cross-Z, Evolto morphed into Ryuga and pretended to be unconscious, until Evolto rose up and started attacking Build. Evolto claims that he absorbed Ryuga and the remaining DNA he had, exclaiming that unless Sento defeats him, his plan will go to waste as the collision will destroy both planets instead. The two clash as Sento keeps downgrading from his previous forms. While Evolto mocked Sento's efforts as the fake hero he created, Sento retorted that it was the power of himself and his friends that was used to create the love and peace in the world. With the aid of Ryuga giving him the Silver Dragon Fullbottle, Sento used it with his Gold Rabbit Fullbottle to become Build RabbitDragon Form and uses his Vortex Attack to vanquish Evolto once and for all, allowing the parallel Earths to merge with each other and create a world without Evolto.

Other Events

Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders

Evolto provides the Hokuto Fullbottles to Sento.

When the world was threatened by the Enigma device, Evolto-possessed Soichi Isurugi made his presence to Sento during his confrontation with Parado. He revealed to Sento that the Nebula Bugsters that had emerged were a hybrid organism created by Nebula Gas infused with the Bugster Virus, and that only Kamen Riders with the power of video games could stop them. Evolto also deduced the timelines of the worlds ran differently before being brought into sync by Enigma. After cluing Sento about Left Kaiser's identity, Kaisei Mogami, he left behind the Phoenix and Robot Fullbottles for him to use as he made a hasty retreat.

Kamen Rider Build: Be The One

To his objection, Evolto's fellow Blood Tribe members took measures to personally see to the destruction of Earth, an outcome which he no longer wished. To that end, "Kengo Ino" commenced the Build Annihilation Plan, compelling the populace of Japan, including Ryuga Banjo, to eliminate Sento. With the Cobra Fullbottle, "Kengo" combined the powers of Ryuga and the Blood Tribe to become Kamen Rider Blood. Evolto, however, intervened by retrieving Sento from defeat. Ultimately, the Blood Tribe trio was defeated by Team Build, with their Lost Fullbottles being recovered by Evolto who voiced that their fates were sealed the moment they decided to betray him.

Build NEW WORLD: Kamen Rider Cross-Z

The resurrection of Evolto

It is revealed that a piece of Evolto attached itself to Ryuga Banjo when the worlds merged, allowing Evolto to live on in the new world. When Killbus appeared and forced Ryuga to reactivate the Pandora Box, Evolto is awakened and emerge as Blood Stalk, engaging him, before escaping with Ryuga, Yui and the Pandora Box. Once Ryuga awakens, Evolto reveals that Killbus is his older brother and the king of their home planet, Blood. But because of his hedonist ways and love for destruction, their planet was destroyed, not before Evolto used his remaining powers to take the Pandora Box and leave. Not strong enough to survive on his own, Evolto takes refuge inside of Ryuga. He reveals the existence of the original Lost Smash creations in their world when Yui reveals she was one and proceeds to attack her when her arguing with Ryuga proved pointless to him.

As the two arrive in the New World's location of an old Faust Research Lab, Evolto uses the Pandora Box to restore the lab and its research notes, revealing it was used to track Ryuga and his Hazard Level and that one of the trials for this was killing Ryuga's parents, which Evolto was personally responsible for. Evolto is attacked by Ryuga until the latter realizes that the former wants to increase his Hazard Level. When Killbus arrives and transforms into Kamen Rider Killbus, Evolto and Ryuga (as Cross-Z Charge) fight him but Evolto was defeated and absorbed into the condensed White Pandora Box Panel, not before he leaves the Dragon Evolbottle with Ryuga to give to Sento.

Evolto is revived and emerges as Kamen Rider Evol when Ryuga is experimented on to create a way to defeat Killbus. He appears to defend Cross-Z Magma from Killbus and the two team-up to fight him. However, Evolto is still unable to defeat him until Ryuga receives the Muscle Galaxy Fullbottle but is unable to use it. Evolto, realizing that Ryuga needs to raise his Hazard Level even further, pretends to betray him and side with Killbus, attacking and choking Yui. When Ryuga successfully activates the Fullbottle and begins to transform, Evolto releases Yui and merges with Ryuga to become Kamen Rider Cross-ZEvol. As Cross-ZEvol, they are able to defeat Killbus, with Evolto appearing as Kamen Rider Evol during the finisher to tell Killbus he lost because Ryuga is human.

After Killbus was defeated, Evolto left Ryuga's body and assumes his Phantom State monster form. He departs to regain his full power but says he'll return once he achieves this.

Personality

"With Kamen Rider Build defeating evil monsters...Misora was able to purify the Bottles, thinking she was doing it for justice. In other words, that was all you existed for. You were merely acting the hero of justice. You were just playing Kamen Rider."
―Blood Stalk unveiling his manipulative persona to Sento[src]

His original personality is almost nothing like Soichi's enthusiastic but laid back paternal demeanor which he emulates, but rather mirrors Gentoku's more, sharing his initial cruelness and ruthless aggressiveness. Like Gentoku, he is more than willing to commit more heinous acts, such as killing several Touto guards using his venom, and changing Eita Kawai's face into that of Shingo Kuwata just to show he could. He views science and the Rider System as instruments for war. Evolto has the traits of a high-functioning sociopath, with his true intentions of destroying the Earth using the Pandora Box coming to light, and his tendency to betray those he comes across with. He manipulates both heroes and villains alike to further his twisted genocidal quest and he has no qualms killing them once they served their purpose. While he is shown to have some genuine sentiment for Sento and Misora as family, he has made it clear that he sees all of them as a means to an end, as shown when he receives the Evol-Trigger and became more intent on reaching his goal of destroying Earth, though his sentiment for the humans had delayed it several times. However Sento having obtained Genius Form and having already recruited the help of his mortal enemy Vernage, Evolto became more short-tempered, irritable, and temperamental since the Riders and Vernage continually ruin his plans, and those emotions amplified after Genius Form gave him the ability to genuinely feel emotions. He will go to petty lengths to make the Riders suffer, though this eventually harms him more than benefiting his own goals.

As Blood Stalk and later Kamen Rider Evol, he is a self-proclaimed strategist. He mostly enjoys viewing battles instead of fighting them, He also seems to have a lot more of an unperturbed and sinister attitude compared to the more focused Gentoku, nonchalantly fooling around even when doing his job as a Faust enforcer. Such is seen when instead of directly engaging Build, he was casually laying back and letting the Square Smash do most of the fighting until it was the right time for him to interfere by making the Smash grow. He also dislikes taking orders from anyone, preferring to do things his own way.

Evolto also viewed his battles with both Sento and Banjo as an experiment to measure their Hazard Level. He was visibly entertained when both of them had a rise in their Levels and gave them hints in return. He isn't even bothered by opposing Gentoku temporarily to let them escape so he can see how strong they become. Because of this, he began viewing humans in a different light, seemingly realizing their potential. When his brother Killbus arrived in the new world, Evolto manages to prove just that, as he resorted to various tactics, ultimately faking defection to his brother's side and threatening to kill Yui in order to raise Banjou's Hazard Level enough to defeat Killbus. He leaves Earth for good, but not before saying that he might possibly return.

Evolto has a tendency to sprinkle bits of Italian in his speech, most commonly saying "Ciao" as a goodbye, which in turn would eventually be one of the phrases announced in the Evol-Driver after an Evoltech or Black Hole Finish is performed.

Since releasing Soichi from his possession and gaining a shapeshifting ability, Evolto continued to masquerade as Soichi out of habit.

Powers and Abilities

Powers

  • Blood Tribe Physiology: As a a member of the Blood Tribe, Evolto possesses all of the various superhuman attributes common among the Blood Tribe.
    • Possession: Evolto can possess any living being to carry out his plans to destroy all living planets he comes across, He is able to wait dormant in the Pandora Box until another living being finds it, at which point, he leaves the Pandora Box to possess whoever discovered it. After achieving the Black Hole Form in the later episodes of Kamen Rider Build, he apparently no longer needs a host for a body to survive, yet he still uses the appearance of Soichi Isurugi for personal preference. He can also use a portion of his own DNA to possess others separately, either to ensure his continued survival or to do his own bidding.
    • Hazard Level: Due to Evolto being an extraterrestrial being, he is able to achieve a Hazard Level of 5, thus allowing him to use the Evol-Driver.
    • Matter Reshaping: Evolto is able to alter matter to any shape he wishes, able to manipulate a tablet computer into a rod-shaped item that he used as a back scratcher.
      • Evolto modifying a victim's face.

        Identity Manipulation: Using a cloud of steam from his hand, he can make anyone's face look like anyone else's; the process seems painful to those who are awake to feel its effects. While the permanence of the change is yet unclear, certain individuals have been shown to retain their new identities for more than a year. Initially thought to be an ability of the Blood Stalk system, this power has since been revealed to be Evolto's. However, it was shown that this power could be applied only if the copied person is dead or killed. This process also seems to have an effect on the subject's physiology as well, as seen when Juzaburo Namba discarded his walking stick and no longer needing glasses to see upon having his appearance changed into that of the dead Masakuni Mido. This process has also been demonstrated to be reversible at Evolto's discretion.
    • Superhuman Speed: Evolto is shown to be able to move at speeds faster than the human eye. He demonstrates this ability by escaping with the Box after defeating Build, and at the nascita where he knocks everyone out. He gains this ability after possessing Ryuga.
    • Superhuman Agility: Evolto was shown to be able to leap at a scale far beyond human capacity after his battle with Build's RabbitTank Sparkling Form.
    • Evolto erasing Takumi Katsuragi's past memories.

      Memory Manipulation: Evolto has shown the ability to erase the memories of others with nothing more than a touch of his hand. Unlike the amnesia induced by Nebula Gas, Evolto's memory manipulation is shown to be complete, causing a total wipe of the person's previous identity. However, with time, some victims have shown to be able to recover partial memories, skills, or even the entirety of their past given proper circumstances.
    • Fire Manipulation: Evolto could shoot a crimson flare from his hand or with his Transteam Gun at the enemy. Its power is enough to destroy Banjo's Dragon Sclashjelly and Sclash Driver. He is able to use this power in both his civilian form and as Blood Stalk, later also carried after he becomes Evol.
    • Pandora Box Control: Evolto could manipulate Pandora Box's power to do his bidding, either to attack the enemy with various phenomenons or to change Pandora Tower's inner structure.
    • Transportation: Evolto is shown with the ability to teleport him (or either others he wishes) to different locations. He was able to bring everyone at nascita to the center of Pandora's Tower instantly.
    • Gene Liquification: If defeated, Evolto can liquefy and scatter his genes, thus ensuring his survival. Kamen Rider Build: Final Stage

Abilities

  • Genius-Level Intellect: To be added
  • Master Tactician: To be added
  • Master Manipulator: To be added
  • Expert Deceiver: To be added
  • Computer Proficiency: Evolto has some level of programming knowledge, as he was able to hack the GPS on a stolen motorcycle, and steal the completed Sclash System data from Sento's computer.
  • Knife Proficiency: Although a very subtle example, Evolto is capable of throwing knives at a high precision rate. The Weaponry Hero

Weaknesses

  • Vernage: Vernage's powers are able to neutralize those of Evolto's. Sento Kiryu made use of this knowledge and used Build Genius Form to transfer Vernage's essence into Ryuga Banjo, so as to prevent Evolto's DNA within Banjo from causing him to go berserk again.
  • Evol-Trigger: Evol's upgrade device is also his primary weakness; when the Transcendence Meter on the Trigger is struck forcefully with an attack, it will paralyze him for a period of time whilst reverting him back to Cobra Form. This weakness is carried over to the Hazard Trigger. Additionally, as shown in The Scientist of Hope, Evolto is unable to use the Evol-Trigger if he is not a complete being, leaving him to choose between fighting at his strongest or having a backup contingency plan should he fall in battle.
  • Genius Fullbottle: The Genius Fullbottle has the ability to counter Evolto's gene liquification ability by transforming them into Smash, allowing the Kamen Riders to defeat them and prevent his survival. Kamen Rider Build: Final Stage

Ability Perimeters:

  • Punching power: 19 t.[2][3]
  • Kicking power: 22.7 t.[2][3]
  • Maximum jump height: 40 m.[2][3]
  • Maximum running speed: 100 m. per 4.7 sec.[2][3]

Similar to Night Rogue, Blood Stalk accesses his main form with the Transteam Gun and the Cobra Fullbottle. Unlike Riders and other Transteam/Kaiser system users, Evolto is almost always seen transformed into Blood Stalk after his identity has been revealed to Sento and the others at nascita.

His stats are not only stronger than most of Build's forms but also surpass Night Rogue's with only speed being slightly lower than his. Stalk also possesses numerous abilities built into his suit. On each wrist, he has extendable venomous tendrils that can shoot out and stab victims, injecting them with venom capable of either paralyzing, killing, or even disintegrating them. He can also create an energy cobra projection through his suit to attack or capture targets. It has been proven that Evolto is extremely proficient with the Blood Stalk arsenal and its abilities granted to him; his skill with the Transteam System, coupled with his enhanced durability, has allowed him to survive multiple skirmishes with Build and Cross-Z, and defeat Night Rogue in a duel.

The true purpose of the Blood Stalk system is to encourage the rise of Hazard Levels in Riders. Thus, he is shown capable of accepting far greater punishments than either Build or Cross-Z. Instead of showing pain or discomfort, Stalk is otherwise enjoying the beatings so long that his opponent's Hazard Level rises. In order to facilitate this, Blood Stalk can measure the current hazard level of Kamen Riders/Smash by simply touching them.

Stalk states that this form is merely temporary, as he uses powers acquired from Mars to stay toe to toe with enemies that are supposed to be stronger than what the Transteam System can put out. This is shown when Stalk was able to fight on par with Build's RabbitTank Sparkling form while Night Rogue was easily defeated by it.

Blood Stalk also has several non-combat abilities. As mentioned by Takumi himself, Stalk's equipment has the ability to change its user's voice tone freely to hide his identity. It is later revealed that the alternate voice is that of Evolto. The Truth of the Pandora Box. Stalk is also able to activate the Guardians’ true programming as sleeper agents of Faust by snapping his fingers. When in need of a quick escape, he can escape any situation by becoming a cloud of red smoke and flowing away.

  • Maximum running speed: 100 m. per 1.1 sec.[5][6]

Cobra Form (コブラフォーム, Kobura Fōmu) is Evol's primary and default form accessed with the Cobra and Rider Evolbottles. Evolto labels this form as "Phase 1" (フェーズ1, Fēzu Wan).

As Evol, Evolto possesses tremendous power, as the Evol-Driver allows him to tap on the full power of the Pandora Box. His perimeters blow far past Grease, Rogue, and even Cross-Z Magma by a small margin. He also surpasses Build's RabbitRabbit and TankTank forms, though he loses to RabbitRabbit by maximum jump height and running speed, and TankTank by maximum kicking power.

Despite these small disadvantages, he still possesses abilities that are almost impossible to counteract, including teleportation and generating energy in his hand to perform an energy blast. He is also able to attack at extremely high speeds and block attacks quite easily, as shown during his first fight with Rogue.

His Evol Cobra Head (EVO-コブラヘッド, Ebo Kobura Heddo) contains the Xeno Head Armor (ゼノヘッドアーマー, Zeno Heddo Āmā) which strengthens its durability within each Phase. Between his EVO Twin Eye Cobra (EVOツインアイコブラ, Ebo Ai Kobura) lies the Master Planisphere (マスタープラニスフィア, Masutā Puranisufia), a device that allows him to determine which celestial body is his next target and formulate the suitable method of destroying it.[7]

In this form, Evol's armor parts are:[8]

  • EVO Cobra Shoulder (EVOコブラショルダー, Ebo Kobura Shorudā): A pair of shoulder armor that allows him to improve attack accuracy. Each has a built-in miniature plant that secretes toxic gases as enhancers of the user's ability.
  • Menace Rush Arms (メナスラッシュアーム, Menasu Rasshu Āmu): Evol's arms. Through an unknown substance that filled his suit, Evol's strength and speed are enhanced. By himself, Evol can manipulate a special aura that can move objects at will or detain his opponents.
  • EVO Xeno Vader Gloves (EVOゼノベイダーグローブ, Ebo Zeno Beidā Gurōbu): Enhanced combat gloves that allow him to create strong punches by manipulating nearby space.
  • Menace Rush Legs (メナスラッシュレッグ, Menasu Rasshu Reggu): Evol's leg units. Through an unknown substance that filled his suit, Evol's strength and speed are enhanced. By himself, Evol can manipulate a special aura that allows him to move objects or run at a tremendous speed.
  • EVO Xeno Vader Shoes (EVOゼノベイダーシューズ, Ebo Zeno Beidā Shūzu): Evol's combat shoes. Each can perform kick attacks by manipulating nearby space.
  • Xeno Chest Armor (ゼノチェストアーマー, Zeno Chesuto Āmā): Chest armor which compresses and produces unknown substances within the Evolbottles. Said armor is stronger than any material on Earth and its durability increases within each Phase.
  • Armilla Reactor (アーミラリアクター, Āmira Riakutā): An Armillary sphere-themed conversion furnace which converts the unknown substance within Evolbottles into strong destructive energy. By completing all Phases, it can demonstrate its true ability.
  • EVO Omniverse Suit (EVOオムニバーススーツ, Ebo Omunibāsu Sūtsu): An enhanced battle suit that can emit blocking energy field, allowing Evol to protect himself from enemy attacks or carry out planetary destruction safely. It can also draw out the user's hidden ability and strengthen them based on the Phase.
  • EVO Material (EVOマテリアル, Ebo Materiaru): Golden armor parts on Evol's body. They can amplify Evolto's special abilities, empower wave attacks, generate annihilation poisons and allow warp teleportation.

Carried over from from Blood Stalk, Evol wields the Transteam Gun and Steam Blade in this form. He is also able to wield any of Build's weapons if he inserts the corresponding Fullbottle into the Evol-Driver along with the Rider Evolbottle.

This form has three finishers:

  • Evol Driver Finishers:
    • Evoltic Finish (エボルテックフィニッシュ, Eborutekku Finisshu) This finisher has two variations:
      • Rider Kick: Evol generates an energy star map beneath his feet that then transforms into a dark red and dark blue energy galaxy that flows into his right foot before delivering an explosive kick.
      • Rider Punch: Evol delivers a flaming punch.
  • Steam Rifle Finishers:
    • Steam Shot (スチームショット, Suchīmu Shotto): Evol channels the powers of an Evolbottle/Fullbottle and performs a powerful steam blast attack.
      • Cobra Evolbottle
        • Elek Steam: Evol shoots a red and blue homing shot coated in electricity
  • Evol Driver + Hawk Gatlinger Finisher:
    • Kikanhou Finish/Full Bullet: Evol inserts the Gatling Fullbottle into the Evol Driver and turns the crank, summoning the Hawk Gatlinger. He then spins the Revol-Magazine of the Hawk Gatling and fires a stream of large energy hawks.

Dragon Form (ドラゴンフォーム, Doragon Fōmu)[11] is Evol's Cross-Z-based form accessed with the Dragon and Rider Evolbottles. Evolto assumes this form while he is in possession of Ryuga Banjo and labels it as "Phase 2" (フェーズ2, Fēzu Tsū).

This form grants higher punching, kicking, and jumping power than Cobra Form, although it is slower by a very small margin. As Ryuga also possesses the ability to use the Pandora Box, Evolto is still able to access the entirety of Evol's power.

Evol's weapon in this form is the Beat Closer.

Ability Perimeters:

Black Hole Form (ブラックホールフォーム, Burakku Hōru Fōmu) is Evol's final form accessed by upgrading Cobra Form with the Evol-Trigger. Evol refers this form as "Phase 4" (フェーズ4, Fēzu Fō). This was Evolto's natural form before being sealed by Vernage, and after achieving it once again, he no longer needs to possess a host.

In this form, Evolto's power rises to a tremendous degree, surpassing all of his previous forms and every other Rider in the series, though his jump height is still much lower than Build's Rabbit Rabbit Form and both his punching and kicking power are slightly lower than TankTank Form. When fighting seriously, Evolto easily overwhelms even the combined effort of Build Genius Form, Cross-Z Magma, Grease and Rogue, and is only defeated when the Kamen Riders exploited a weakness of the Evol-Trigger.

While still possessing all the abilities of Cobra Form, Evolto gains the ability to generate and manipulate small black holes. Once one of these black holes makes contact with an enemy, it traps them within itself and completely destroys them, leaving no trace behind.

  • Evol-Driver finishers:
    • Black Hole Finish (ブラックホールフィニッシュ, Burakku Hōru Finisshu) This finisher has three variations:
      • Evol spins rapidly as a miniature black hole is generated behind him. The black hole then compresses into halo-like rings of energy as Evol delivers a powerful flying kick to the enemy, sending them into the black hole which kills them after a period of time.

Rider Statistics

Ability Perimeters:

After possessing Utsumi, Evolto transforms into Kamen Rider MadRogue by inserting the Bat and Engine Fullbottles into the Evol-Driver and turning the lever.

His main feature is the explosion-proof CyBat Armor (サイバットアーマー, Saibatto Āmā) that allows MadRogue's gear to continue functioning in battle even if his engine-like features blow up. His chest is equipped with the MR Steam Generator (MRスチームジェネレーター, Emu Aru Suchīmu Jenerētā) that boosts his capabilities through specialized steam and allows a temporary boost in speed and energy attacks. For aerial combat, MadRogue can deploy a pair of Mad Night Flyers (マッドナイトフライヤー, Maddo Naito Furaiyā) from his back.[18] Through his MadRogue Head (マッドローグヘッド, MaddoRōgu Heddo), he can utilize the Metal Bat Blade (メタルバットブレード, Metaru Batto Burēdo) to establish a link with Hard Guardian and Clone Smash units.[19]

MadRogue wields the Nebulasteam Gun and Transteam Gun as his personal weapons and the Steam Blade as his sidearm. He is also able to wield any of Build's weapons if he inserts the corresponding Fullbottle into the Evol-Driver along with the Rider Evolbottle.

Kamen Rider MadRogue consists of the following parts:

  • MadRogue Head (マッドローグヘッド, Maddorōgu Heddo): MadRogue's helmet.
    • Cybat Armor (サイバットアーマー, Saibatto Āmā): Armored parts of MadRogue's head. It is explosion-proof and will shield the user from explosions from the engines built into the armor.
    • MR Signal (MRシグナル, MR shigunaru): Data collection system in MadRogue's helmet. It collects data in real-time and performs emergency repair on damaged parts of the suit. It also manages the condition of the body. It can be fine-tuned by tracing the signal up and down.
    • Metal Bat Blade (メタルバットブレード, Metaru Batto Burēdo): The bat-like crest on the helmet. It can establish a link with Hard Guardian and Clone Smash units to command them.
    • Mad Seeker Eye (マッドシーカーアイ, Maddo Shīkā Ai): MadRogue's eyes. It has a built-in night vision sensor and can detect heat sources and movement. The built in ultrasonic sensor allows him to fight in complete darkness.
    • Air Face Duct (エアフェイスダクト, Ea Feisu Dakuto): A built-in gas mask in the helmet. It removes harmful substances from the air when breathing and can discharge toxic gases.
    • MR Face Guard (MRフェイスガード, MR Feisu Gādo): A device that protects Kamen Rider MadRogue's head. In response to an enemy's physical attack, it emits a wave that cancels out the impact to nullify the damage.
  • Cybat Armor (サイバットアーマー, Saibatto Āmā): The purple and white armor on MadRogue. It is explosion-proof and will shield the user from explosions from the engines built into the armor. The chest is equipped with a device called MR Steam Generator (MRスチームジェネレーター, MR Suchīmu Jenerētā) that increases user's speed. The user can also deploy the Mad Night Flyer (マッドナイトフライヤー, Maddo Naito Furaiyā) to fly.
  • MR Unlimited Suit (MRアンリミテッドスーツ, MR Anrimiteddo Sūtsu): Shock resistant bodysuit of Kamen Rider MadRogue. It can release the physical limiter and unleash the hidden physical ability of the user while offering protection from damage. In addition, the special liquid that fills the inside of the suit can enhance the affinity between the special micro-body Mech Virus (メックヴァイラス, Mekku Vu~airasu)} and the user.
  • Bad Steam Shoulder (バッドスチームショルダー, Baddo Suchīmu Shorudā): MadRogue's shoulder armor. They maintain and manage the operating state of the internal combustion engine incorporated in each part of the suit by removing excess heat. They can also spray toxic gas using the components of the Fullbottle, develop a smokescreen, and launch special bullets.
  • High Burst Rush Arm (ハイバーストラッシュアーム, Hai Bāsuto Rasshu Āmu): MadRogue's arms. The built-in engine and drive unit which are fueled by the components of the Fullbottles significantly increase the strength and speed of movement in the arms.
  • Night Raid Edge (ナイトレイドエッジ, Naito Reido Ejji): The blades on MadRogue's arms. The sharpness of the blade increases the darker the area is. A blow in complete darkness is instantly fatal.
  • Mad Vengeance Glove (マッドヴェンジェンスグローブ, Maddo Vu~enjensu Gurōbu): MadRogue's gloves. They are reinforced and have sharp claws at the fingers to allow for slashing attacks. The power of the attacks increases the more the user hate the enemy.
  • High Burst Rush Leg (ハイバーストラッシュレッグ, Hai Bāsuto Rasshu Reggu): MadRogue's legs. The built-in engine and drive unit which are fueled by the components of the Fullbottles significantly increase the strength and speed of movement in the legs.
  • Mad Vengeance Shoes (マッドヴェンジェンスシューズ, Maddo Vu~enjensu Shūzu): MadRogue's shoes. They are reinforced and have a sharp claw at the sole that can inject a powerful neurotoxin. The power of the attacks increases the more the user hates the enemy.

Evolto (Phantom State)

Evolto


Evolto (Evolti Grasper equipped)


"Ready, go! Feverflow! Fuhahahahahaha! Fuhahahahahahahaha!"
―Transformation announcement[src]

Statistics:

Phantom State (怪人態, Kaijin Tai) 怪人態 is Evolto's monster form obtained by absorbing the Lost Panel of the Pandora Box with 10 black and gold Lost Fullbottles inserted and activating the Evol-Trigger's Feverflow Mode.

While in this form, Evolto acquires a monstrous degree of power, enabling him to tank nearly everything the Kamen Riders can throw at him and his basic attacks releasing violent shock waves that destroy his surroundings.

Along with keeping all of Black Hole Form's powers, Evolto also gains the ability to instantly warp to different planets, allowing him to harvest their energy and grow even stronger.

Turning the Evol-Driver's lever in this form allows Evolto to perform the Black Hole Break (ブラックホールブレイク, Burakku Hōru Bureiku): Evolto summons a black hole large enough to consume an entire planet.

After Evolto absorbed an alien world, he temporarily gained the Evolti Grasper (エボルティグラスパー, Eboruti Gurasupā) arm gauntlets, bringing him a step closer to his Ultimate State. The Scientist of Hope

Evolto's only weakness in this form is that he needs all ten Lost Fullbottles in the Lost Pandora Panel to be able to sustain it. This is shown when Sento, using the Hazard Trigger in Genius Form, purified the Castle and Hammer Lost Fullbottles, forcibly reverting Evolto to Black Hole Form.

Appearances: Build Episode 45, 48-49, NEW WORLD: Kamen Rider Cross-Z

Evolto (Ultimate State)

Evolto

Statistics:

After absorbing the moon's energy and some of the Earth, Evolto evolves his monster form into its Ultimate State (究極態, Kyūkyoku Tai).

By maintaining the energy of the planets Evolto has absorbed using the Evol Trigger, Ultimate State allows Evolto to use Phantom State at full capacity. However, this form's true potential is immeasurable due to Evolto being able to absorb planets and evolve endlessly.

In this form, after Evolto absorbed the moon, he gains the Evolti Grasper (エボルティグラスパー, Eboruti Gurasupā) arm gauntlets, which are able to direct electric energy at enemies. After absorbing some of the Earth, he also gains the Evolti Voider (エボルティヴォイダー, Eboruti Vu~oidā), shoulder-mounted blasters that fire extremely powerful and focused lasers, which are capable of one-shotting a Rider at full health out of their transformation.

However, due to the energy sustaining this form being managed by the Evol Trigger, damaging the device itself will cause Evolto to become paralyzed for a significant amount of time.

Appearances: Build Episodes 48-49

Evolto (Ultimate Form)

Evolto (Ultimate Form)

Evolto evolved into his Ultimate Form (究極の姿, Kyūkyoku no Sugata), a white-colored version of his Monster Form powered by the whole energy of the Pandora Box.

This form is exclusive to Kamen Rider Build: Final Stage.

Cross-ZEvol

Cross-ZEvol

"Muscle Galaxy! Bura! Ciao! Are you ready? (Techno Rock music) Ginga muteki no kinniku yarō! Cross-ZEvol! Panēi! Maji panēi![24]"
―Transformation announcement[src]

Rider Statistics

  • Rider Height: 200 cm.
  • Rider Weight: 125.5 kg.

Ability Perimeters[25]:

  • Punching Power: 67.4 t.
  • Kicking Power: 73.9 t.
  • Maximum Jump Height: 90.8 m.
  • Maximum Running Speed: 100 m. per 1 sec.

Cross-ZEvol (クローズエボル, Kurōzu Eboru)[26] is Cross-Z's second final form accessed by using the Muscle Galaxy Fullbottle in the Build Driver. It is hence known as the Galactic Invincible Muscle Guy (銀河無敵の筋肉野郎, Ginga Muteki no Kinniku Yarō).

Ryuga performs the transformation along with Evol, who forms the Black Hole Snap Ride Builder, and combines both of them into one as the transformation completes. However, Ryuga normally takes complete control of this form. When performing the Galaxy Finish, Evolto briefly takes control, which makes Cross-ZEvol's eyes glow red.

This form has three finishers:

  • Muscle Finish (マッスルフィニッシュ, Massuru Finisshu): Cross-ZEvol turns the Vortex Lever once and performs an upgraded version of the Dragonic Finish, a punch augmented with an energy dragon.
  • Galaxy Finish (ギャラクシーフィニッシュ, Gyarakushī Finisshu): Cross-ZEvol turns the Vortex Lever two times and uses a black hole to teleport to the enemy, before delivering a punch covered in purple energy that creates a small black hole upon impact.
  • Muscle Galaxy Finish (マッスルギャラクシーフィニッシュ, Massuru Gyarakushī Finisshu): Cross-ZEvol turns the Vortex Lever three times and performs a Rider Kick accompanied by energy constructs of Cross-Z and Evol, similar to Fourze Fusionstates' Rider Fusion Drill Kick.
This form is exclusive to Build NEW WORLD: Kamen Rider Cross-Z.

Behind the Scenes

Portrayal

Evolto is voiced by Tetsuo Kanao (金尾 哲夫, Kanao Tetsuo), who previously voiced Namakelder in Happiness Charge Pretty Cure!. As Blood Stalk and Kamen Rider Evol, he is portrayed by suit actor Kazuya Okada (岡田 和也, Okada Kazuya) regardless of the body he possesses.

While possessing or impersonating others, the physical body is portrayed by that respective actor while retaining Kanao's voice at Evolto's discretion.

Etymology

'Evolto' and 'Evol' are both taken from the English words 'evolution' and 'revolt'. 'Evolution' also sounds similar to 'revolution', which is used liberally in Evol's Black Hole Form announcements.

Concept Art

Evolto was designed by Tamotsu Shinohara (篠原 保, Shinohara Tamotsu).


Notes

  • Blood Stalk's cobra motif, along with Night Rogue's bat motif, is part of the recurring bat/cobra/spider trio in the Kamen Rider franchise, a tribute to the first two Shocker monsters as well as the first monster to be upgraded.
  • As a hint to Stalk's true identity as Soichi, the collar on Blood Stalk's suit was modeled after the collar of a space suit.[27]
  • The CGI model of Blood Stalk's Energy Cobra is a reuse of part of Kamen Rider Ouja's Venosnaker.
  • The Blood Stalk suit would later be retooled for Kamen Rider Ikazuchi’s Rider form.
