And now a poll for our Villains this year, the Horoscopes Zodiarts!

Scorpion/Sarina Sonoda

• Sarina Sonoda is the youthful and beautiful homeroom teacher of class 2-B who teaches classical literature. Though she appears to be a teacher every student in the school loves, she is actually a member of the Horoscopes who uses her pleasant facade to know the students better in order to find ideal suitors for Zodiarts Switches. She herself was originally an AGHS student until she met Hayami, who gave her a Zodiarts Switch that enabled her to become the Canis Minor Zodiarts. Eventually, after her Zodiarts Switch assumed its Last One state and her Resurrection Star glowed, Ms. Sonoda discarded her humanity and evolved into the Scorpion Zodiarts. While in her Scorpion Zodiarts state, Ms. Sonoda's voice deepens to sound masculine, possibly to avoid suspicion regarding her identity. Out of Gamou's inner circle, Ms. Sonoda is the most loyal to his cause and serves as his right hand.
  Using the special Scorpion Switch to assume her Zodiarts form, the Scorpion Zodiarts uses a kick-based fighting style. She is also armed with powerful claw gauntlets and a scorpion's tail-like ponytail that doubles as a whip and can inject an agonizing venom into her victims. The Scorpion Zodiarts initially works behind the scenes, distributing the Zodiarts Switches to students that want to seek revenge against those who have slighted them. The Scorpion Zodiarts later appears before Kamen Rider Fourze during the events of the Chameleon Zodiarts's vendetta against Miu, though originally ordered by Gamou to not eliminate the Kamen Rider and instead fights him when his meddling becomes a hindrance. But once she begins to give Miura a new Zodiarts Switch, Ms. Sonoda is given full permission to kill Kamen Rider Fourze. During her plot to kill off Gentarou, Gamou gives Ms. Sonoda a boost in power to awaken her Supernova status, giving her the ability to become the scorpion man-like Scorpion Nova. This enables her to battle the now visibly stronger Kamen Rider Fourze, with her lower body capable of transforming into a large scorpion body with a gigantic tail, being equal in size to the Powerdizer when transformed. Her body in this form can also amass enough energy to destroy a city. However, the scheme fails as she is defeated by Kamen Rider Fourze in space with his Big Space Rider Rocket Drill Kick. Spirited away by Hayami with her identity protected, Ms. Sonoda's Zodiarts Switch is taken away from her until she pleads Gamou into giving it back to her in response to the appearance of Kamen Rider Meteor. However, losing against Kamen Rider Meteor shortly in a one-on-one fight, Ms. Sonoda is seemingly banished into the Dark Nebula by the Virgo Zodiarts as punishment for her repeated failures. Though later revealed to be alive and in suspended animation within the M-BUS, Sonoda's Scorpion Switch is given to Gamou before he entrusts its use to Tatsugami. Her disappearance is covered up soon after to make it seem that she is on a sabbatical and then a resignation due to health reasons.

Libra/Kouhei Hayami

• Kouhei Hayami is the principal of Amanogawa High School. He is an attractive and charming young man who has a Ph.D in Physics, that most of the student body and faculty, even the mothers of the students, save for Mr. Ohsugi, fall for. In actuality, he is a loyal member of the Horoscopes who uses the Libra Switch to transform into the Libra Zodiarts who uses his khakkhara called Dikē to create illusions to fool his targets. Though capable of holding his own in a fight, the Libra Zodiarts is one of the weaker members within the Horoscopes in terms of combat capabilities as he overwhelmed when the Kamen Riders have access to their upgrade forms. He is a shrewd character with an inquisitive nature and has managed to prevail thus far, due to him actively avoid direct confrontation with the Kamen Riders and undying loyalty to Gamou. True to the nature of his Zodiarts form, which is based on a star sign that takes the form of a scale, Hayami has a habit of using terms related to weight like "light" and "heavy" when talking to others.
  In his first appearance before the Kamen Rider Club, he saves the unconscious Ms. Sonoda while casting an illusion over her to protect her identity from Kamen Rider Fourze. Hayami then reluctantly takes over her duties in the distribution of Zodiarts Switches, targeting those among his prized pupils who have the potential to become Horoscopes. He also rarely intervenes with the businesses of his Zodiarts recruits by fighting Kamen Rider Fourze. After Ms. Sonoda is sent to the Dark Nebula, Hayami is ordered by a worrisome Gamou to speed up his recruitment strategy. Playing an indirect role in bringing Natsuji Kijima into the Horoscopes' ranks, not tolerating the newcomer's blatant disrespect towards him on many levels, Hayami takes advantage of Kijima's defeat by Kamen Rider Meteor Storm to get him sent into Kijima into the Dark Nebula while he gives Gamou the Cancer Switch. Using a field trip to Kyoto have Kamen Rider Fourze's presence reveal four altars gathering Cosmic Energy to The Hole above the city, with Tatsugami assigned to oversee his progress, Hayami destroys the four altars so only The Hole above AGHS can amass Cosmic Energy. Though he succeeds, his defeat by Kamen Rider Fourze deems him as of no further use to Gamou.
  However, Hayami's desperation of being exiled causes him to manifest his Supernova state in the form of the Eye of Laplace, a power that enables him to see a person's "Fate of the Stars" to see not only one's potential to become a Horoscopes member but eventually locate other Horoscopes Switches. With this new found power, Gamou allows Hayami to stay so they can put his new power in recruiting the Capricorn, Aquarius, and Taurus Zodiarts. But as the final phase of Gamou's plan begins, playing a role in Emoto's death and in Dark Yuki's creation, Hayami begins to question the Horoscopes' goal and where he fits in it once his usefulness comes to an end before being welcomed into Gamou's inner circle as he learns the nature of the Day of Awakening. From there, Hayami formulated a scheme to make it seem that he betrayed Gamou to protect Ran while ensuring she becomes the Pisces Zodiarts, giving his Libra Switch to the Kamen Rider Club as a proof of his conviction before it ended up with Tatsugami who secretly gives it back to him. But once everything goes to plan, Hayami reveals his true colors before taking a Rider Super Galaxy Finish meant for the Sagittarius Zodiarts. Drifting into the Dark Nebula, satisfied with his self-sacrifice, the Libra Zodiarts is vaporized by the the vortex's lightning.

Virgo/Kuniteru Emoto/Tachibana

• Kuniteru Emoto originally was a research associate in OSTO with Rokuro Utahoshi and Mituaki Gamou studying Cosmic Energy. However, Emoto was jealous of Utahoshi, who he always saw as the vibrant Earth, with Gamou as the illuminating sun and himself as the moon, paling in comparison to either but reflecting the sun's light. Forming a partnership with Gamou, Emoto chose power over friendship and stole the Zodiarts Switches from the OSTO space station, something Emoto would regret later on. He had a brief scuffle with Utahoshi before escaping in a Lunar Module, leaving his former friend stranded on the moon. Soon after, vowing to take Utahoshi's place as the Earth in their relationship to Gamou, Emoto became one of the first members of the Horoscopes: The Virgo Zodiarts. Serving as the Horoscopes' judge and executioner with his voice altered to sound female, the Virgo Zodiarts is a specialist in space-time warping, originally using it to travel from Amanogawa High to the Kyoto Space University where he works as a professor studying The Hole above Kyoto. As the Virgo Zodiarts, he is one of the most powerful members of the Horoscopes. Wielding a halberd called Rhodia, he can project barriers strong enough to deflect even Kamen Rider Fourze's Cosmic States Limit Breaks, fire black hole-like orbs that eats away cleanly at anything they touch, and conjure a portal to send his victims to what he claimed to be the Dark Nebula. In his Zodiarts form, the Virgo Zodiarts can also use his angelic wings to fight or send out feathers to deliver messages. In his human form, Emoto maintains a humble and clumsy facade and displays the same ability to turn his eyes red as Gamou.
  Emoto also uses his teleportation powers to travel to the M-BUS satellite where he dons a mask and adopts the alias of "Tachibana", Ryusei's contact as Kamen Rider Meteor. Using voice-altering software and claiming to be from the Anti-Zodiarts Union, Emoto recruited Ryusei into becoming Kamen Rider Meteor and gave Kengo the Gate Switch which eventually lands him on the Rabbit Hatch. These actions are part of his ultimate motive to actually subvert Gamou's agenda. Furthermore, lying that he sent former members to die in the Dark Nebula, Emoto actually sent former Horoscopes members to the M-BUS where they enter suspended animation for their own protection. During the events of Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max, in his Zodiarts form, Emoto attempted to capture Nadeshiko for Gamou before being forced to fall back after being hit with the Double Rider Rocket Punch.
  After sending Ryusei to Amanogawa High, telling him to keep his identity a secret, Emoto proceeds to watch over the events to follow as both the Virgo Zodiarts in watching Hayami's progress after banishing Ms. Sonoda and playing a part in Kijima's evolution into the Cancer Zodiarts, and as Tachibana in giving Ryusei the Meteor Storm Switch and allowing him to remain a Kamen Rider after the Kamen Rider Club learned his identity, on the condition they ensure no one else finds out. By that time, unaware of his benefactor's identity while curious of his intent to help people, Ryusei begins to suspect the Virgo Zodiarts to have his own agenda. After The Hole in Kyoto is negated, Emoto transfers to Miraikan where he becomes an instructor to Kengo, Yuki, and Tomoko. When Tomoko learned of his identity as the Virgo Zodarts while inspecting the Dark Nebula, Emoto sends her to the Dark Nebula to conceal his secret before proceeding to intimidate Yuki, Miu, Shun, and JK to leave the Kamen Rider Club. By that time, using his Tachibana guise to train Gentaro into using the Cosmic Switch without having to rely on friendship, the answer of which he believes lies within ruthlessness. Failing to take account for Kengo's ingenuity and the Libra Zodiarts' evolving Supernova powers, Emoto's identities as both Tachibana and the Virgo Zodiarts are accidentally revealed to both the Kamen Rider Club and the Horoscopes along with his agenda. Once doubting the power of friendship as he had experienced its frailty first hand, he regains faith in the sentiment after seeing how Gentaro is able to use Cosmic States again due to his reinforced faith in the friendship he forged, as well as how the Kamen Rider Club chooses to stay by his side eventually despite the danger looming ahead. Soon after, he and Gentaro become friends. Mortally wounded by the Sagittarius Zodiarts prior to spiriting Kengo away to reveal the truth of his father's death, subsequently pleading him to stop the Horoscopes. Greatly weakened, Emoto is landed the final blow by the Leo Zodiarts after teleporting them and the Libra Zodiarts away from Kengo. Losing the Virgo Zodiarts Switch to Gamou as he is left to die, Emoto's final thoughts are the knowledge that he has gained new true friends and has done something worthwhile. However, Emoto leaves behind a flash drive that Kengo finds, the contents of which detail his origins and the window of opportunity should the Day of Awakening start.

Leo/Kou Tatsugami

• Kou Tatsugami is a skilled martial artist who is fanatically loyal to Gamou, serving as both his personal aide and bodyguard due to his skills at dispatching multiple opponents effortlessly. He is shown to be able to crush two walnuts with his bare hand. He has a habit of drinking liquor alone in a quiet environment, taking offense to anyone who disrupts him at the time and attacking them regardless if they are allies. He is also a member of the Horoscopes as the Leo Zodiarts, one of the strongest fighters of the group with his massive clawed gauntlets and powerful lion's roar shock-wave attack, super speed, and toughness capable of shaking off Limit Breaks effortlessly. The Leo Zodiarts, compared to other Horoscopes, can also produce his own personal kabuki-themed retainers known as the Leo Dustards that use twin Duswords. Prior to his formal meeting with the Kamen Rider Club, Tatsugami assumed his Zodiarts form to oversee the transaction of Gamou giving a set of Zodarts Switches to Lem Kannagi. Tatsugami is sent by Gamou to oversee Hayami's progress in Kyoto, assuming his Zodiarts form to over power both Kamen Riders at once without any help. Meeting Tojiro Goto, Tatsugami cryptically revealed the new member's ability might be useful in locating the Core Switch, proven later by Gamou himself that he is now able to sense faint traces of the mysterious Switch. Tatsugami has a unique physique where he can use the Zodiarts Switches of other Horoscopes members, his natural fighting abilities allowing him to effectively fight as the Aries, Cancer, Scorpion, Capricorn, Virgo, and Aquarius Zodiarts better than their original Switchers. After executing Emoto for his betrayal, Tatsugami takes over the role of obtaining the final two Horoscopes Switches.

Cancer/Natsuji Kijima

• Natsuji Kijima is an arrogant second-year student with A sharp tongue and who displays hostility toward anyone who irritates him. Originally president of the AGHS rakugo club, Kijima found a Zodiarts Switch by chance that the Libra Zodiarts dropped during a fight with Kamen Rider Fourze and becomes the Pegasus Zodiarts, acquiring a new-found taste for power. Using his new found power, Kijima seeks revenge, while also for fun, on the new 2-B homeroom teacher Ms. Haruka Utsugi for taking his rakugo fan by attacking any martial artists he finds, mimicking her fighting style so the Kamen Rider Club would believe she is the Switcher. However, the club learns the truth before Kamen Rider Fourze Magnet States destroys the Pegasus Zodiarts. Unfortunately, with the Virgo Zodiarts's help when his Zodiarts form resurrects, Kijima is able to evolve into the Cancer Zodiarts, who is armed with sharp and heavy pincers on his left forearm, capable of cutting just about anything, liquify himself to retreat or disappear, and his body is protected by a hard-spiky carapace strong enough to withstand even the Rider Super Electromagnetic Bomber Limit Break unscathed. All of the above combat-specific features, along with the ability to remove the life force of people and place them in comas, enable him to become the most powerful Hororscopes warrior so far. Although being the fifth Horoscopes and winning Gamou's favor, Kijima flaunts his strength around without discretion unlike his other Horoscopes comrades, and constantly picks fights with the Kamen Riders. He has also made an enemy out of Hayami by not only insisting on being treated as a an equal, but also belittling the principal at every turn.
  While learning Kamen Rider Meteor's identity, proceeding to mess with him for his amusement, Kijima somehow manages to evoke his latent Supernova powers on his own, enabling him to transform into the more crab-like Cancer Nova, with even more impregnable armor than his regular Cancer Zodiarts form. This amuses Gamou even more, although the chairman does muse behind Kijima's back that the Cancer Zodiarts's evolution is going too fast. After being defeated in his Supernova form by Kamen Rider Meteor's newly obtained Meteor Storm form, Kijima limps onto the AGHS campus and drops his Zodiarts Switch, which Principal Hayami takes. Though Kijima pleads with the principal, saying that he knows the true identity of Kamen Rider Meteor and the information would prove useful enough to win back Gamou's favor, Hayami states his intent to do away with him regardless. Finding himself in the form of a meddling detective by Hayami's illusion, Kijima is sent to the Dark Nebula by an unsuspecting Virgo Zodiarts after Hayami talks her into it. Hayami later conceals his actions by claiming that Kijima had died in battle, unaware that Kijima is actually in suspended animation within the M-BUS, as he gives gives Gamou the Cancer Switch before it is entrusted to Tatsugami.

Aries/Tatsumori Yamada

• Tatsumori Yamada is a transfer student at SBHS who is originally a quiet member of AGHS's drama club. However, upon arriving to Subaruboshi High, Yamada used the Zodiarts Switch he obtained to become the Lepus Zodiarts before evolving into the sixth member of the Horoscopes known as the Aries Zodiarts. Armed with a scepter called Coppelius, the Aries Zodiarts emits an aura that can slow down or speed up a person's bodily functions, allowing him to easily tire people out as well as rendering people unconscious. While not shown to be powerful in direct combat, the Aries Zodiarts's ability to put his opponent to sleep makes him extremely dangerous regardless, even to fellow Horoscopes if he wants to. He abuses this ability and developed a god complex to the point of totally disregarding the Horoscopes' interest in general and not meeting with Gamou. Yamada transfers to Subaruboshi High to break away from the chairman's scrutiny, and takes on the title of "The Apostle of Sleep" as he gets the entire school under his control and has everyone act in the roles he assigns them. However, being able to speed up bodily functions of a person means that he can easily revive someone as well. He is eventually brought before the chairman by the Virgo Zodiarts and Hayami advises to him to brace himself for a scolding. To the principal's surprise however, Gamou is rather delighted with Yamada's performance in SBHS, praising Yamada's work so far to be very individualistic and gives him full permission to do as he pleases.
  Though Ryusei is only looking for the Aries Zodiarts under Tachibana's orders initially, he sees a way to save Jiro in the said Zodiarts. As a result, against Tachibana's orders, Ryusei decides to make a deal with Yamada, by killing Kamen Rider Fourze, to save Jiro. Honoring his end of the bargin, Yamada proceeds to orchestrate the Kamen Rider Club's deaths when Ryusei arrives to save them before Gentaro overpowers the Aries Zodiarts as Kamen Rider Fourze Cosmic States. Enraged, the Aries Zodiarts briefly transforms into Aries Nova, with his horns changing shape while his eyes turn blue and his cape retracting. Though his full abilities in Supernova form are not seen, firing spheres of yellow energy at his opponent, the Aries Zodiarts is defeated by Kamen Rider Fourze's Rider Super Galaxy Finish. As the resulting attack places him in a coma, Yamada's Aries Switch is retrieved by the Virgo Zodiarts and given to Gamou, who then gives it to Tatsugami for safekeeping.

Capricorn/Tojiro Goto

• Tojiro Goto is a recent transfer student to AGHS who happens to be an old friend of JK's from junior high school. He is a rocker with a hearty appetite, though his guitar playing is terrible. Goto is found by Hayami, using his Eye of Laplace, to possess the potential to evolve from the Zodiarts for Lyra into the Capricorn Zodiarts, and is given a Zodiarts Switch prior to evolving into the said Horoscopes member. Unlike other Horoscopes members, he bears no ill will to anyone and just wants to be big as a rocker. As the Capricorn Zodiarts, he is armed with an electric guitar like weapon called Multi-stringed Koto Uruk that is able to manipulate sound, generating devastating sonic shock waves and entrancing people with his music, as well as trapping people with a Cosmic Energy manifestation of the musical staff. The entranced people will go on a "high" for a period of time before suffering a serious adrenaline crash that can last for days. The Capricorn Zodiarts can also use his music to resonate with certain Switches, with Tatsugami setting up a theory that Goto can find the Core Switch. When Gamou hears the hypothesis, he is impressed and bestows the Supernova powers to the Capricorn Zodiarts to increase the chance that they may succeed in this task.
  After becoming one of the Horoscopes, Goto tracks down JK to convince him to reform their band as the new Gene God Dark Night Carnival after discovering that JK is hosting the popular DJ Gene internet radio show, improving JK's singing and his guitar playing through his Capricorn Zodiarts form's powers. However, Goto really wants to use the radio show as a means to brainwash their listeners into becoming crazed fans, though it begins to weaken them overtime. When JK discovers this, he tries to cancel the program, but Goto reminds him of his father's past, which changes his mind, and JK quits the Kamen Rider Club upon revealing they will have a live show a few days later. However, Gentaro, having been taught a song by JK's father that he used to sing to his son when growing up, manages to get through to JK who realizes that he should not be attaining his dream like this. Despite Gentaro's poor guitar skills, JK's terrible singing and the Capricorn Zodiarts' jeering, Gentaro manages to break his spell on the student body, whom all flee when they see a Zodiarts nearby, thus infuriating him. He battles Kamen Rider Fourze once more, but with JK's return to Gentaro's circle of friends, he is able to utilize Cosmic States once more and the Capricorn Zodiarts is defeated before he can even use the Supernova abilities Gamou gave him. Goto is then spirited away to Gamou's headquarters where his Capricorn Switch is confiscated and his memory erased, rather than being banished to the Dark Nebula, as he confirmed the Core Switch is still active.

Aquarius/Erin Suda

• Erin Suda is a third-year student at AGHS who transferred to AGHS from an American school. She is an elite student, although she is not perfectly fluent in Japanese. She came to the school to pursue her dreams of becoming an astronaut like her father prior to his retirement before even getting the chance to go into space by participating in the school's annual Astronaut Selection Exam. Found by the Libra Zodiarts, Erin is given the means to evolve into the Aquarius Zodiarts. As the Aquarius Zodiarts, she is armed with a whip called Nectar and the vases of water on her shoulders can be used to heal herself or others, making her immune to even Limit Breaks from Kamen Rider Fourze Cosmic States unless both vases are shattered at almost the same time. She meets Gentaro and quickly befriends him, but is distressed after learning her new friend is also Kamen Rider Fourze, someone whom she is tasked to eliminate. Upon meeting Yuki during the Astronaut Selection Exam, Erin expresses utter disdain towards the girl as she reminds her of a colleague of her father's, a people-person she sees has robbed her father of his last chance to go to space. Her disdain of Yuki grew further after a misunderstanding where she thought Yuki had sabotaged her in the exam. On the contrary, thanks to Yuki's clever thinking, Erin is actually saved by Yuki instead. Though she eventually manages to make peace with Yuki, Erin states that they cannot be friends, due to her respect and dedication to Gamou as a Horoscopes member. These conflicting sentiments lead her to a conclusion that one of them must fall, which ultimately leads her to have a final showdown with Gentaro. She is eventually defeated when both vases on her shoulders are shattered, robbing her healing abilities once and for all. After being defeated by Fourze Cosmic States, the Virgo Zodiarts spirits Erin anyway to take her Aquarius Switch and erases her memory of the whole ordeal. Soon after, unable to attend Miraikan alongside the latter, Erin meets Gentaro and Yuki while starting her friendship with them anew.

Taurus/Yuta Sugiura

• Yuta Sugiura is a third year student and AGHS's student body president, having replaced the previous president Sayaka Mibu after she is hospitalized. While participating in the school's annual Astronaut Selection Exam, Sugiura is found by the Libra Zodiarts whose Eye of Laplace show him to have the potential to evolve into the Taurus Zodiarts. He hold steadfastly onto the school's policies of allowing as much freedom as possible to the student body previously and constantly bickered with Sayaka over idealistic differences. This eventually indirectly led to her being injured and hospitalized and to everyone's surprise, he lost his cool, seriously panicked and rushed to Sayaka's side immediately after hearing the news from Shoko. With his newfound powers, motivated by his feelings for Sayaka under the delusion that he is doing it for the right reasons, Sugiura creates the Amanogawa Campus Bylaws, various rules that limit the individuality of the student body. As the Taurus Zodiarts, his main power is to force people into keeping with a contracted promise through the use of his scepter called Gu-anna as well as taking people's souls and turning them into loyal drones. He is also physically imposing, being both strong and fast in executing short range attacks. Sugiura nearly manages to get the entire school under his control before Gentaro gets Sayaka to convince Sugiura to break his hold, through her breaking a list of bylaws he imposed. Sugiura finally breaks down before her and Gentaro as he is incapable of punishing her for he terrorized the school for her sake in the first place. Though the Virgo Zodiarts offers him a final chance to redeem himself, the Taurus Zodiarts opts to fight the senior Horoscopes instead before being sent into the Dark Nebula. Though later revealed to be alive and in suspended animation within the M-BUS, Sugiura's Taurus Switch is given to Gamou.

Sagittarius/Mitsuaki Gamou

• Mitsuaki Gamou, previously referred to as the red-eyed man, is Amanogawa High School's school board chairman who often uses space metaphors in his speech. As a child, Gamou reach the call of the Presenters at the time of the Apollo 11 exploration, motivating him to join NASA and the Russian Federal Space Agency in attempts to fulfill his promise to meet them. While extremely affable and encouraging of others in conversation, Gamou has ultimately always been friendless and finds the concept beneath him, thinking of himself as the sun that all others revolve around. This nature is compounded by his ability to hear the call of the Presenters, which led to Gamou's goal in life being to find a way of making contact and fulfilling what he sees as his destiny.
  Twenty years prior to the beginning of the series, while a member of OSTO, Gamou and Utahoshi found the Core Switch that the Presenters sent to the moon as a test for sentient life in the solar system. The two cracked the majority of the puzzle of the Core Switch, but clashed over the method by which the Presenters should be contacted, with Gamou's egocentric nature leading him to favor the immediate forcible evolution of humans into beings able to withstand the rigors of transwarp travel using Zodiarts Switches over Utahoshi's plan to create the Fourze System which would take generations to complete. Three years after the finding, Gamou had Emoto steal the completed Zodiarts Switches from the OSTO lunar station and murder Utahoshi, though Emoto instead left him stranded on the moon. A decade before the events of the series, Gamou built Amanogawa High directly under The Hole, ostensibly in order to foster a love of space exploration in future generations. But in reality, with a funding arrangement set up with Foundation X, Gamou utilized the school to create and raise Zodiarts in order to find and gather all twelve members of the Horoscopes for the Day of Awakening. To that end, Gamou became one of the first Horoscopes, the powerful Sagittarius Zodiarts who can generate a bow on his left forearm called Gilgamesh to unleash a barrage of Cosmic Energy arrows known as the Apostolos. Because of his saturation with massive levels of negative cosmic energy, even in his human form Gamou is shown to possesses supernatural abilities such as giving other members of the Horoscopes the ability to acquire Supernova powers and the ability to conduct hypnotic suggestion that he uses on outsiders to drive them away, thus keeping his true agenda a secret from prying eyes.
  During the first half of the series, Gamou uses the principle he set up in his school to encourage the manifestation of individuality in students so that Zodiarts selected from among them can do whatever pleases them in hope they can become Horoscopes, even if it means doing extensive damage to the school. Only the Horoscopes members are accounted for if they are defeated by a Kamen Rider one time too many. Gamou almost sends Principal Hayami to the Dark Nebula for failing him too many times until he suddenly acquires the power known as the Eye of Laplace, convincing Gamou to revoke banishment and get their Horoscopes membership to ten while learning from Tatsugami that the Core Switch still exists. With only two Horoscopes left, after Emoto reveals his true colors in aiding Kamen Riders Fourze and Meteor, Gamou makes himself known in his Zodiarts form as he easily defeats the two Kamen Riders. During the incident with the Gemini Zodiarts, whom he had a personal interest in due to Yuki having heard the Presenter like he had, Gamou begins to suspect Kengo to possess the Core Switch. Although he does not initially see the boy to be a threat, his identity being revealed in the process, Gamou's Day of Awakening is thwarted by Kengo using his Core Child powers to negate the Horoscopes Switches. Knowing that Kengo would need to die for the Day of Awakening to resume, Gamou elects to perform Supernova on himself to attain the Sagittarius Nova form, trading his bow and armor for a much lighter body. In this state Gamou can perform a flying kick attack similar to a Rider Kick with his leg surrounded by an aura of Cosmic Energy resembling an arrow. After sending the Leo Zodiarts to attack the Rabbit Hatch and lure out Kengo, who proceeds to leave Earth, Gamou arrives and crushes the Core Switch that maintains Kengo's life.

Gemini/Dark Yuki

• The Gemini Zodiarts is a doppelgänger of Yuki Jojima known as "Dark Yuki," created when Yuki is forced by the Libra Zodiarts and the Leo Zodiarts to activate a Zodiarts Switch. As a result, instead of melding into her Zodiarts body, the Gemini Switch causes the darkest aspects of her personality to be given a physical form that is identical to Yuki, but with a white mask that has blank expression on her face. Due to Yuki's passion for space, Gamou sees Dark Yuki as a kindred spirit due to Yuki hearing the Presenter as he had. As the Gemini Zodiarts, she has an unorthodox fighting style and is armed with two types of exploding cards: Red cards known as Lynceus that explode upon contact and the blue cards called Idas that explode as the Horoscopes wills them to. Her Supernova ability allows the Gemini Zodiarts to produce a clone of herself that doubles as a living explosive. As a result of the separation, while acting on Yuki's darkest desires, Dark Yuki reveals that she has a 24 hour window to usurp Yuki as the dominant aspect while the original self ceases to be. Though she succeeds in that retrospect, taking everything Yuki has for her own, Dark Yuki loses her dominance over Yuki thanks to Gentaro giving the girl a very strong memory to reverse the process. After Dark Yuki is destroyed, Tatsugami retrieves the Gemini Switch for Gamou.

Pisces/Ran Kuroki

• Ran Kuroki is a new first-year student who is proficient in swimming and Aikido. Though Gentaro tries to befriend her and her best friend Haru Kusao, she rejects his friendship outright due to a bad experience with senior students from her old middle school, that convinced her to trust no student older than her and to protect Haru. However, Ran's ideals led to Haru to embrace being the Musca Zodiarts as he rejects her pleas to discard the Zodiarts Switch so she can protect him. When Haru throws away his friendship bracelet into the river, Ran goes to look for it on her own while refusing Gentaro's help. But after Gentaro found the bracelet with the Kamen Rider Club's help, having not told him what she iss looking for, Ran decides to put her trust in her new seniors. Ran is able to snap Haru out of his madness by apologizing for making him feel weak and useless through her protection, allowing Kamen Rider Fourze to destroy the Musca Zodiarts without any further psychological problems to deal with later. Afterwards, she and Haru both ask to join the Kamen Rider Club, and they are made provisional members until Haru is fully recovered.
  Ran is later revealed to be the last predestined member of the Horoscopes: the Pisces Zodiarts with the ability to liquify herself, swim through solid surfaces, and shoot high pressure water streams. Though Hayami attempted to keep her from becoming the Pisces Zodiarts, Ran is forced into transforming regardless when the Leo Zodiarts brutalizes the principal, as she sees no other way to get out of the situation and save the principal. Though a member of the Horoscopes, her Pisces Switch starts out colored blue to signify its immaturity. Additionally, Ran still considers herself a part of the Kamen Rider Club and resolves to use her newfound powers to fight Gamou and Tatsugami. However, having set her up to become one of the Horoscopes, Principal Hayami has Tatsugami abduct Haru to force Ran into fully maturing her Pisces Switch before taking it from her. Ran is later taken to the hospital where Haru looks after her.
