==History==
===Background===
Evolto was born on the Planet Blood. After his older brother Killbus' lust for destruction led to their homeworld's destruction, Evolto had managed to escape with their native artifact, the Pandora Box. Alongside the final members of his race, later called the Blood Tribe, they roamed the galaxy annihilating countless worlds and consuming their energy to become more powerful. After landing on Mars, Evolto used the Pandora Box to raise the Pandora Tower and unleash a black hole.
During the final confrontation against the Martian Queen Vernage, both his body and the Evol-Driver were obliterated. Evolto's fractured essence was preserved inside the Pandora Box. After a protracted period of time, a piece of Evolto attached itself to a space probe sent from Earth. When the probe returned to Earth, the fragment transferred itself to security guard Yuri Banjo and merged with her unborn son, Ryuga Banjo, who was born a month later. The child shared Evolto's DNA but lacked his consciousness and abilities.
Thirteen years later, astronaut Soichi Isurugi discovered the Pandora Box while exploring the Martian ruins. Evolto took over Isurugi's body and used his memories to produce sixty Fullbottles. Upon arrival on Earth, Evolto attempted to use the Pandora Box to raise the Pandora Tower. However, Vernage also reached Earth and removed the Bottles' essence, causing the Sky Wall rising in its stead. After being committed to a mental institution, Evolto managed to escape and got in touch with Shinobu Katsuragi to repair his Evol-Driver and create some new Bottles. Evolto also made Isurugi's daughter, Misora to purify the Nebula Gas into the Fullbottles.
For the last seven years, Evolto continued inhabiting Isurugi's body. Alongside Takumi Katsuragi and Gentoku Himuro, he founded the group Faust to conduct Nebula Gas experiments. He would acquire a Transteam Gun and the Cobra Fullbottle to become Blood Stalk. After Katsuragi uncovered his alien identity, Evolto wiped the scientist's memories and swapped his appearance with Taro Satou's. Evolto framed Ryuga Banjo for Katsuragi's claimed murder and hid the amnesiac scientist in a rainy alleyway to be "found", renaming him "Sento Kiryu".
===Indoctrinating Kamen Rider Build===
One year after Sento gained notoriety as Build, Isurugi met up with him whether he still remembered his past, but Sento struggled 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 informed Sento about Ryuga Banjo and sent him to go meet up with the escaped convict. Sento learned that Banjo was also experimented on 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 Banjo guidance with the battles against the Smash while imparting wisdom at times.
The search for Takumi Katsuragi's murder and Banjo's jailbreak led to the team searching for Masahiro Nabeshima. Right when Sento purified Nabeshima's transformation into a Smash, Blood Stalk neutralized and knocked him unconscious. Isurugi brought Sento back to the lab, having apparently saving him from the encounter. After Nabeshima was re-purified by Sento after turned into a Smash a second time, he clued Sento about the Pandora Panel in the lab's wall, similar to the one that Faust had. While Isurugi was confronted for this, he laughed at the prospect of being a "stylish" villain. While he confessed that he used to be a member of Faust, Isurugi claimed he left the group after Faust exploited Misora's purifying abilities.
While Sento decided to continue looking into his own past, Blood Stalk decided to make his presence known to the amnesiac scientist. As a high-level executive of Faust, Blood Stalk participated in the abductions of several people to inject them with Nebula Gas. Blood Stalk often came into conflict with his accomplice Night Rogue, who had bigger plans for Kamen Rider Build and Ryuga Banjo. While he made his presence known, Blood Stalk often got mistaken of being Takumi Katsuragi, but would never confirm or deny that fact when questioned.
Blood Stalk continued to assist Night Rogue in his plan to plan to seize the Pandora Box from the Touto Institute. Despite causing a setback, he graciously handed the relic to Faust's custody. While Stalk often let Build and Cross-Z get away and secured the Pandora Box for himself, this angered Gentoku Himoru as he questions his true allegiances. Despite hiding the Pandora Box with Namba Heavy Industries after forming a partnership with Juzaburo Namba, Sento and Banjo eventually retrieved the relic from him.
However, Sento would catch on to suspect that Isurugi was Blood Stalk. While confronting Isurugi, he took the opportunity to revealed himself. While confronting Sento again as Blood Stalk, he was defeated by Build RabbitTank Sparkling, but not before informing him that Gentoku Himuro was actually Night Rogue. After Isurugi entered Sento's lab to gather data on the Sclash Driver, Misora learned of her father's apparent betrayal. Sento eventually learned of Isurugi's involvement in erasing his memories and that he was previously Takumi Katsuragi. After his alliance with Touto served his purpose, Blood Stalk 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 as Blood Stalk declared that the war for the Pandora Box had begun.
===Kamen Rider Heisei Generations Final: Build & Ex-Aid with Legend Riders===
When the world was threatened by Kaisei Mogami's Enigma, the Evolto-possessed Soichi Isurugi met Sento during his confrontation with Parado. He revealed to Sento that the Nebula Bugsters were hybrid organisms created by Nebula Gas infused Bugster Virus, and that only Kamen Riders with the power of video games could stop them. Evolto deduced the timelines of the worlds ran differently before being brought into sync by Enigma. After cluing Sento about Kaisei Mogami, he left behind the Phoenix and Robot Fullbottles for him to use as he vanished.
===The Japanese Civil War===
With Faust's dissolution in Touto, 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. He expressed his desires to see Sento and Banjo grow as Kamen Riders and looked forward to it.
Taking notice that Sento was falling behind due to his Hazard Level being slightly lower, Stalk gifted him with the Hazard Trigger, a forbidden item created by Katsuragi that could evolve Build into the Hazard Form. While the Hazard Trigger ended up sending Sento into a mindless rage that killed Aoba in the process, Isurugi met with the depressed Sento and remarked how he thought he would have fought the war without hurting anyone and even optimism had limits. Isurugi motivated Sento to participate in the Proxy Battle between Touto and Hokuto, even training with Sento in using the Hokuto and Seito Fullbottles as the latter prepared for his duel with Grease.
After watching the Proxy Battle between Build and Grease ending with Touto's victory, Blood Stalk quickly turned against Hokuto as Seito's forces have invaded the nation. It was revealed that he had been colluding with Seito from behind the scenes, with him and Namba Heavy Industries striking a deal with Masakuni Mido to move Faust's base of operations there. After reuniting with his former accomplice Gentoku Himoru, who had been exiled from Touto, Stalk watched his Gentoku's progression as Kamen Rider Rogue as he witnessed the pain and torture it took for him to achieve such power.
Taking notice that Vernage had reawakened inside of Misora, Blood Stalk decided to avoid his "daughter" from now on. He would also drop information about the Namba Children, cluing Sento in regarding Sawa Takigawa's true origins as Juzaburo Namba's spy. After the proxy battle between Touto and Seito ended with victory for Touto, Blood Stalk was summoned by Namba to kill Masakuni Mido when he decided to honor his promise to end the war. Blood Stalk used his powers to modify Namba's face into that of the late Seito Prime Minister, allowing him to personally take control of the nation and launch his own invasion of Touto using the full arsenal provided by Namba Heavy Industries.
===ROGUE===
During Gentoku's past during the founding of Faust, the Evolto-possessed Soichi Isurugi made his presence known to Gentoku Hiromu and Takumi Katsuragi as Namba Heavy Industries' representative. He joined their inner circle due to his own information regarding the knowledge with Pandora Box and the Nebula Gas. Isurugi later killed Hotei to secure Gentoku's position as the Touto Prime Minister's aide.
Flashforward to Gentoku's exile from Touto, Gentoku was later imprisoned in Namba Heavy Industries' detention facility in an attempt to raise his Hazard Level. Blood Stalk had set his sights on Gentoku as the ideal candidate as Seito's Kamen Rider, believing he had strong enough emotion to use the belt, despite Utsumi's denial. While Gentoku endured being beaten senselessly by the other prisoners, this did not take away his desire to become a Kamen Rider and got his wish to undergo the Nebula Gas treatments.
As the experiments increased his Hazard Level to 3.5, Gentoku was sent to an isolated section of the facility to fight the prisoners to the death to increase his Hazard Level. While Gentoku survived enough to raise his Hazard Level to 4 and use the Sclash Driver, Blood Stalk had his former subordinates, Kakizawa and Matsui, transformed into Remocon and Engine Bro's to battle Kamen Rider Rogue. Rogue's body reached its limit and cancelled the transformation. Stalk and Utsumi left Gentoku as they had more plans for him in the future.
===The Evolto Revolution===
Although the war between Touto and Seito had come to a close, Blood Stalk decided to press on by raising the Pandora Tower from the Sky Wall. While the Kamen Riders march on against Seito's forces, they would be informed of Blood Stalk's true nature as Evolto, the alien responsible for the destruction of Mars. Noticing the progress with Banjo's evolution and his transformation into Cross-Z Magma, Stalk was elated to find the perfect vessel in Banjo and declared everything he had worked hard for was falling into place. While Banjo was depressed upon discovering his connections with Evolto, the former became determined to use his power as a Kamen Rider to fight for love and peace.
After Stalk planned in Prime Minister Himuro's abduction, Evolto demanded Sento for the Evol-Driver in exchange for the Touto Prime Minister's life. The Kamen Riders head to the trade which went south as Evolto would not cooperate. Evolto recovered the Evol-Driver and emerged as Kamen Rider Evol, killing Taizen Himuro in the process. Evol later poisoned Sento and told everyone he would die within three days if he did not receive the antidote.
While Banjo managed to defeat Evol in order to cure Sento from his condition, Evolto took this opportunity to eject himself from Soichi Isurgui's body to possess Banjo instead and access Evol's Dragon-based Phase 2 form. While he later completed the formation of the Pandora Tower, he ceased his destruction to the world until he could reactivate his Evol-Trigger. This led to Build using the power of the Pandora Panel in an attempt to sacrifice himself, but this backfired and Evolto switched over to take over Sento's body instead. With Sento now in Evolto's possession, he accessed Evol's Rabbit-based Phase 3 form, but was still unable to activate his Evol-Trigger, believing humans were not strong enough to handle such power. 
Although Evolto's separation with Banjo rendered him unable to transform, his determination allowed him to reignite his genes and become Great Cross-Z. However, Evolto managed to complete the Evol-Trigger and access his Black Hole form, jettisoning Sento, which reverted him back to Takumi Katsuragi instead. Now restored back to his true form, Evolto proceeded to shapeshift into Soichi Isurugi's appearance. While the Kamen Riders formed an alliance with Namba Heavy Industries to take down Evolto, he proved to be a formidable foe and killed the Juzaburo Namba and Washio brothers. Evolto proceeded to take the form of Masakuni Mido to control Seito's forces, with Nariaki Utsumi by his side as Kamen Rider MadRogue. During another invasion of Seito, Evolto witnessed Sento Kiryu regain his memories and transformed into Kamen Rider Build Genius Form.
===Kamen Rider Build: Be The One===
As the Blood Tribe commenced the Build Annihilation Plan to brainwashing the country's populace to turn against the Kamen Riders, Evolto voiced his objection to his kin. However they began to act entirely on their own due to distrust between them and Evolto, who chose to not destroy the Earth right away after achieving his perfect form. With the Cobra Lost Bottle, Kengo Ino combined the powers of Ryuga Banjo 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 Build, with the Lost Bottle recovered by Evolto who voiced that their fates were sealed the moment they betrayed him.
===Quest of the Lost Bottles===
Following the victory of Build Genius Form, Evolto commended Sento for conceiving a weapon that could rival Evol's power. Evolto began to collect the Faust Fullbottles, now dubbed "Lost Bottles", as a means to increase his strength. During an encounter with Build Genius, he was shocked that Sento was able to land a blow before he could even use the Evol-Trigger, causing Evolto to feel human-like emotions and expressing anger after losing to a human. While causing him to senselessly attack his adversary, Sento declared to do whatever it would take to build back whatever Evolto destroyed.
Eventually, Sento's biological father, Shinobu Katsuragi, resurfaced and was revealed to be working with Evolto from the shadows. Evolto began 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 was over and the country had been reunified. With a few Lost Bottles remaining, Evolto faced the quartet of Kamen Riders where they seemingly defeated Evolto. However, while Shinobu revealed his true ruse after containing his gear, Evolto returned after possessing Utsumi and killed Shinobu. Evolto evolved into a horrifying new monster form and announcing his intention to destroy Earth, but his transformation was undone after Sento used the Hazard Trigger with the Genius Bottle to purify a few Lost Bottles and restore Evolto back to Black Hole.
As a plan to eliminate Evolto once and for all, Sento intended to use the Black and White Panels to merge their Earth with one where the Sky Wall did not exist, using Evolto himself as the catalyst. Shortly after Evolto's national television broadcast, the Kamen Riders raced up to Pandora Tower. While creating replicants of the adversaries for the heroes to face, this resulted in the deaths of Kazumi Sawatari and Nariaki Utsumi in the process. When the three remaining Riders charged at Evolto, he was unimpressed at their performance and took an opportunity to transform back into his monster form. However, Gentoku sacrificed himself to immobilize Evolto, allowing Sento to trap Evolto and tether the worlds. However, at the last second, Evolto grabbed Banjo and dragged him into the ripple between the two Earths.
===Final Battle And Demise===
Arriving in the ripple between Earth and the world without Sky Wall, Evolto waited for Build as he assumed Banjo's appearance. While Evolto mocked Sento's efforts as the fake hero he created, his opponent retorted that it was the power of himself and his friends that was used to build love and peace in the world. Banjo managed to grab ahold of Evolto's body and gave him his Silver Dragon Fullbottle. Sento then accessed the RabbitDragon form to vanquish Evolto once and for all, allowing both worlds to merge with each other and create a new world without Evolto.
===Build NEW WORLD: Kamen Rider Cross-Z===
It was revealed right before the creation of the New World, a piece of Evolto attached itself to Ryuga Banjo when the worlds merged. When Killbus appeared to target him for carrying Evolto's genes, this caused the Pandora Box to reactivate and reawaken Evolto as Blood Stalk. He escaped with Banjo, Yui Mabuchi and the Pandora Box. While Banjo angered by this, Evolto took refuge inside of Banjo. They were forced to cooperate to defeat Killbus, while Evolto provided information about Banjo's origins and the Lost Smash. Although Cross-Z Charge and Blood Stalk battled Killbus, they were easily overwhelmed and Killbus defeated Evolto, who leaves the Dragon Evolbottle behind.
After Sento analyzed the Dragon Evolbottle, he amplified Evolto's genes from Banjo to create a new power-up item that could defeat Killbus. This resulted in Evolto's resurrection as Kamen Rider Evol. He later appeared to assist Cross-Z in the final battle against Killbus. Once the Muscle Galaxy Fullbottle was created, Evolto attacked Yui to strengthen Banjo's resolve to become Kamen Rider Cross-ZEvol. Together, they were able to defeat Killbus, with Evolto remarking to Killbus that he lost because Banjo was human. After the victory, Evolto in his Phantom State subsequently departed the planet promising to return at full strength.
===Kamen Rider Outsiders===
Years after he departed the planet following the defeat of his brother Killbus, Evolto suddenly returned to Earth and made his presence known by saving Zein (controlling Yuto Sakurai's body) from being finished off by Kamen Rider Zero-Three. He then departed through a wormhole with Zein.
==Video Game Appearances==
==Personality==
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 then leaves Earth for good, but not before saying that he might possibly return, which he eventually did a few years later in a brand new form.
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. 
***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 Banjo.
**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.
**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.
***Shapeshifting: After reaching his fourth Phase, Evolto gains the ability to assume a human form, namely that of his former host, Juzaburo Namba, and even Masakuni Mido. 
**Gene Liquification: If defeated, Evolto can liquefy and scatter his genes, thus ensuring his survival. 
===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. 
===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.

==Notes==
*Some merchandise has spelt his name as Evolt.http://cross-z.jp/img/goods_t.jpg
*As a hint to his identity as Soichi, the collar on Blood Stalk's suit is modeled after the collar of a space suit.http://blog.livedoor.jp/shfiguarts/archives/1069025804.html
*A recurring gag with Evolto undercover as Soichi was his incompetence in brewing coffee. In Build NEW WORLD: Kamen Rider Cross-Z, it was suggested in Evolto's research notes that his species has different taste senses compared to humans.
**In an interview with Evolto in Weekly Shonen Magazine, he speculates that the reason why his coffee is said to be unpleasant was a result of making the black coffee taste like a "black hole" that it unintentionally tastes bitter.
*To enhance and make more authentic Maekawa's performance of Soichi who had been possessed by an alien from day one, the producers had informed him of Evolto's true nature and identity, which he used to his advantage."Spaceship" vol.161 (SUMMER 2018.Summer), June 30, 2018
