Horoscope

The Horoscopes, alternatively called the Twelve Constellations of the Zodiac are Zodiarts that are completely evolved from their human selves, keeping their human bodies, unlike less-advanced Last One Zodiarts & are based on the constellations of the Western Astrological Zodiac.

They answer directly to Lucius Hope, who share his ideals & believe themselves as superior to all others & that they were chosen by the universe itself. This is likely a side effect to the addiction of Cosmic Energy as seen on regular Zodiarts. They are distinctive in that they wear heavy cloaks that cover nearly all of their body, which they discard when entering battle & can be used as protection against certain attacks.

Any Horoscope can create side troops using Cosmic Energy called the Stardust Ninja Dustards, which dissolve into dust after they are defeated.

Originally starting out with four members as the series begins, the Horoscopes work within MWHS to give Zodiart switches to various students in order to build their membership to twelve as part of Hope's master plan. Though the Kamen Rider Club members were in the dark about this intent, Kamen Rider Meteor reveals the truth to them during his formal introduction.

Horoscope Zodiarts possess personal Switches that are different from regular Zodiart Switches which are red & gold in color (although, certain conditions must be met to fully awaken the switch, such as surpassing Last One stage or, like Calanthe's Pisces switch, must meet the condition that Pisces willingly pressed her switch), are marked with their respective astrology signs, & are oblong-shaped with no bottoms.

A Horoscope's most powerful ability is to undergo a transformation called Supernova to either assume a more powerful form or gain a new technique. The Supernova can only be used for a limited period of time as overuse in a short period of time will cause the Zodiart to be destroyed.

Once all twelve Horoscopes are gathered, Sagittarius will cause a mysterious event called the Day of Awakening where he uses all twelve Horoscope Switches & the atmospheric vortex above the school known as The Hole to reach the Presenter(s), a mysterious sentient will of the universe that calls out to humanity, by conjuring the real Dark Nebula. But in the process, the Dark Nebula's gravitational pull would suck in all of America.

The membership had finally been risen to twelve, but there are now no Horoscopes active as they were all either defeated/killed at the hands of the Kamen Riders, or by other members of the Horoscopes.

Thanks to Libra faking defection, Sagittarius had all 12 Horoscope Switches after getting Pisces' Switch. However, it was thanks to Jeong Thrussell releasing a burst of Cosmic Energy from the Core Switch in his body that disrupted the Day of Awakening.

Lucius Hope/Sagittarius
The leader of the Horoscopes, is the first to appear in the show & is the most powerful Zodiarts. Though appearing as a human for most of the series, he unveils his Horoscopes form around Virgo's death. He is currently deceased, having dissolved into Cosmic Energy as a side-effect of his evolution.

Konani Hamm/Virgo
The fourth Horoscope to be seen on the show, & was Sagittarius's right hand. He was killed at the hands of Leo while fighting him & Libra when Sagittarius learns of Virgo's hidden agenda against him.

Roger Abelli/Leo
The third Horoscope member to be seen on the show, having a deep connection to Sagittarius, & is fanatically loyal to him. He is currently deceased, as he dissolved into Cosmic Energy after his defeat by Kamen Rider Meteor.

Kelvin Platt/Libra
The second Horoscope member to be seen on the show. He was the one that recruited most of the Horoscope members into their fold. He once, willingly, allowed Leo to use his Switch, allowing two of his Dustards to evolve into Leo Dustards. He is currently deceased, after taking a hit from Quadronaut meant for Sagittarius. The hit then sent him flying backwards into an open rift into the Dark Nebula, where he is vaporized by the dimension's lightning.

Magdalene Layton/Scorpion
The fifth Horoscope member to be seen on the show. She is currently banished into the Dark Nebula by her fellow Horoscope member, Virgo. Her Switch was later used by Leo. It is unknown where her current whereabouts is after Virgo told the Kamen Rider Club about sending them to the M-BUS & confirming the exact state of the Dark Nebula.

Somerled Heffernan/Cancer
The sixth Horoscope member to be seen in the entirety of series & the fourth member on the show. This Horoscope was once the Pegasus Zodiart but has since evolved into the Cancer Zodiart.

Cancer was banished into the Dark Nebula when Libra disguised him as a rather nosy detective from an earlier episode. Presenting Virgo with the Detective/Cancer, Libra was able to fool Virgo into sentencing him to eternal imprisonment within the Dark Nebula to protect Sagittarius' plans for Milky Way. After his banishment, the Cancer Switch falls into the possession of Libra, though Libra does not use the switch. Cancer does, however reappear - though not as it's original holder. Through Leo's unique powers, he is able to transform into Cancer.

Once Virgo is exposed as being Mandarin, Virgo reveals to the Kamen Rider Club that he did not banish Cancer to the Dark Nebula, but rather he has him held in suspended animation on the M-BUS space station. We are not privy to Cancer's whereabouts at the end of the series. He is not seen again, & we can either assume he made it back safely - or that after Mandarin's death Cancer remained at the M-BUS space station in suspended animation.

Drake Horn/Aries
The seventh Horoscope member, which evolved from the Lepus Zodiart when he transfered from MWHS to Pleiades High School. He actually had no interest of joining the Horoscopes despite being one of Libra's prospects, but only wanting to rule over Pleiades High School. He's currently in a coma after his fight with Quadronaut in his newly obtained Cosmic States. His Switch was later used by Leo.

Theodore Quinones/Capricorn
The eighth Horoscope member, which was found by Libra using his Eye of Laplace, showing his potential to evolve past the Lyra sign. He is currently living a normal teenage life, having his memories of being Capricorn erased after his defeat at Quadronaut's hands. His Switch was later used by Leo.

Ainsley Ackerman/Aquarius
The ninth member, as well as the second member that has a female body. She was found by Libra using his Eye of Laplace. She is currently living a normal teenage life, having her memories of being a Horoscope removed from her after her defeat at Quadronaut's hands. Her Switch was later used by both Leo & Sagittarius.

Shaw Wuopio/Taurus
The tenth member, who was found by Libra using the Eye of Laplace during the Astronaut Selection Exam. He was banished into the Dark Nebula after he attacked Virgo to protect his new friends. It is unknown where his current whereabouts is after Virgo told the Kamen Rider Club about sending them to the M-BUS & confirming the exact state of the Dark Nebula.

Dark Letitia/Gemini
The eleventh member, who was found by Libra using the Eye of Laplace under the command of Sagittarius. Gemini is actually the embodiment of Letitia's inner darkness that became a separate entity, thanks to the particular nature of evolution concerning people who have the potential to become a Gemini Zodiart. After being weakened when "Light" Letitia took back dominance, Gemini is exorcised by Quadronaut in Cosmic States. Her Switch was later used by Leo.

Calanthe Blake/Pisces
The twelfth & final member, who was found by Libra using the Eye of Laplace. Pisces had previously appeared during the Musca Zodiart incident, where she instigated most of the things that went wrong in that arc. Unlike the others, Pisces is not joining Sagittarius' fold, & is in fact rebelling to not allow the Day of Awakening to be realized. However, Libra & Leo used her very nature to protect the former Musca Zodiart to get herself out in the open & took Pisces' Switch from her after beating her.

Musical Themes
The Horoscopes have many themes, two reoccurring scores being "Horoscope Switch" & "Power of the Horoscope".
