This is a partial character sheet for Kamen Rider Fourze. Visit here for the main character index. Subjective trope and audience reactions should go on the YMMV page.
A Zodiarts is created when an ordinary human uses a Zodiarts Switch to create an avatar body of Cosmic Energy, transforming and giving him/her incredible powers. The human (known as a "Switcher") can use the Switch to transform freely between his/her normal and Zodiarts forms as many times as he/she wishes.After a certain number of uses (catalyzed by the user's rage and negativity) the Zodiarts Switch will mutate into a form known as "Last One". If the Switcher uses the Zodiarts Switch after this happens, their human body is ejected by the Zodiarts body upon transformation. While this increases the Zodiarts's power, it carries a risk that the Switcher will not be able to turn back to normal.

General Tropes
- All-Encompassing Mantle: Exclusive to the Horoscopes. Until they junk them, that's when shit goes down.
- Animal Motifs: Sometimes done with Zodiarts based on constellations that aren't animals.
- Pyxis (also known as the Mariners' Compass) is specifically bug-like, and even Altar (self-explanatory) has bug-like mandibles which combined with her Playing with Fire ability, makes her a firefly.
- Perseus has a wolf motif to him. Medusa's head (re: the original legend) is even incorporated into the design so he's got a bunch of snakes as well.
- Libra has antennae and a smaller mantle under his cloak that make him look like a cockroach. And Leo actually did call him a cockroach upon Libra's faked Heel–Face Turn.
- Virgo invokes this with deliberately bird-like wings that even shed feathers.
- Inverted with Dragon — the dragon bits are shifted towards the arms, making him look nondescript.
- Aquarius is the first to knowingly avert this. Though she does look slightly like a jellyfish.
- Taurus, of course, looks similar to a giant bull.
- Sagittarius has a bird motif, as it is the scientific name of the secretarybird.
- It is a misconception that the myth behind the constellation of Sagittarius, the Archer, is that it was the centaur Chiron, who is actually represented by the aptly named constellation Centaurus. Sagittarius represents the satyr Crotus, so if the Sagittarius Zodiarts was going to be accurate, it'd be a man with goat legs and horns.
- His Super Nova form's design is a mixture of a Horoscopes Switch and a bug. Interesting enough, in this form he has his own version of a Rider Kick and Punch.
- Not surprisingly, Pisces is a fish.
- Deadly Upgrade: Kengo implies that when using a Zodiarts Switch in its "Last One" stage, the user may not be able to turn back. Considering their soul effectively leaves their body in a coma to control the Zodiarts body, he probably has a point.
- Gentaro mentions in Episode 8 that Miura (Orion Zodiarts) is still in hospital. Then episode 13 comes. He's well, but not going back to Amanogawa due to withdrawal symptoms.
- Episode 14 reveals that when a former switcher is given a new switch, it immediately enters Last One state.
- Episode 14 also reveals the true final form of a Horoscope, its Supernova form! However, if used wrongly, it could destroy them.
- #15 reveals that a Zodiarts can surpass the Last One state, which could lead to them becoming a Horoscope. And #22 revealed the first student to become a Horoscope.
- As it turns out, using a Zodiarts Switch for too long, such as Gamou and Kou, has a nasty side effect: whereas a normal Horoscope returns to normal when beaten, these two can't. If their Zodiarts form is destroyed, they die.
- This trope was the entire reason Kengo's father was opposed to them in the first place: they're a quicker route to power than the Fourze Driver, but they're also far riskier with far more drawbacks.
- Defeat Equals Explosion: Justified; a Zodiarts body is made of Cosmic Energy, and upon defeat that energy is violently released in an explosion. This notably causes problems, as the stronger Zodiarts have so much Cosmic Energy in them that defeating them could potentially result in an explosion powerful enough to level of a city if done wrong. Fourze either has to take them into space to defeat them properly or an attack that siphons off Cosmic Energy has to be used.
- Drunk on the Dark Side: The users tend to become more irrational and insane as they continue to use the Switch. This is undone with its destruction, however.
- Evil Feels Good: A frequent consequence of using a Zodiarts Switch. At least one former Switcher - Miura (Orion) - develops withdrawal symptoms after his Switch is destroyed.
- Evil Is Easy: When compared to the Fourze System, a Zodiarts Switch is the quicker of the two to reach the Presenters, but at the cost of various factors.
- Evil Knockoff: Both the Fourze System and the Zodiarts switches were created by reverse engineering the Core Switch. However, where the Fourze Driver was the intended end result by the Presenters (as shown with Kengo being designed to use it to warp back to them), the Zodiarts Switches were created by Gamou out of impatience with how long it would take and refusing to allow anyone else to reach the Presenters before him. As a result, while a quicker means to obtain power and theoretically capable of allowing a human to reach the Presenters, they're also far more dangerous and risk destroying the user both physically and mentally.
- From Nobody to Nightmare: Invoked in the same way as Kamen Rider Double.
- The Gloves Come Off: The Horoscopes junk their black capes when they go into battle. Not that there's some kind of Restraining Bolt in action, just Rule of Cool really.
- Made of Explodium: The released Cosmic Energy could take out an entire city block or more, so Fourze has to be careful when using a Limit Break.
- Of note, defeating the Zodiarts itself doesn't destroy it completely - the only way to take it out for good is to destroy the Switch by turning it off once and for all.
- Monogender Monsters: Averted in a fashion similar to Kamen Rider Double. Like the Dopants, uncovering the true identity of a Zodiarts is part of the story. To add to the mystery, the Zodiarts refrain from speaking, have their voices digitally distorted, or a separate voice actor is used until their identity is revealed.
- One-Winged Angel: Some of the "Last One" transformations.
- In #14 Horoscopes have the ability go Supernova turning them into giant monsters!
- Taken beyond eleven in in #15. What is beyond Last One? The evolution to a Horoscope-level Zodiarts!
- Personality Powers: The Zodiarts evolve in reaction to their host's abilities and desires. For example Unicorn gained a sword due to Nitta's fencing ability and Hound fit Teruhiko's fondness for chains as its main weapon.
- Shout-Out
- Lynx, with its Super-Speed ability, brings to mind the Smilodon Dopant.
- Leo is awfully similar to Rook the Lion Fangire.
- Capricorn takes after a goat not just in appearance; his affinity for music is a reference to Pan, the goat-like god in Classical Mythology.
- Sorting Algorithm of Evil: the latter half of the series eschews normal Zodiarts to have actual Horoscopes as MOTWs, starting with Aries in #31.
- Superpowered Evil Side: The Zodiarts are pretty much extensions of their anger and wrath, but sometimes they can get even worse. Case in point: the case of Cygnus who was, in fact, a student's Split Personality.
- Villainous Breakdown: Apparently the most effective way to accelerate a Switch's evolution to its "Last One" stage.

Other Zodiarts
Toshiya Miura/Orion Zodiarts
Toshiya Miura/Orion
Portrayed by: Masanori Mizuno
- Camera Fiend: His family owns a photography studio. At the end of Episode 14, he quits the Football team and joins the Photography Club.
- Carry a Big Stick: The Lemnos Club in Last One
- Cold Turkeys Are Everywhere: The real reason why he's not going back to school. At the end of Episode 14, he recovers thanks to Gentaro giving Miura all the photos Mari took of him.
- Defeat Means Friendship: Gentaro extends his hand of friendship to him. However, his promise of friendship isn't enough to stop Miura's withdrawal symptoms from the Switch. Fortunately, at the end of Episode 14, he takes Gentaro's hand of friendship for good.
- The Dog Bites Back: The part of his Freudian Excuse for accepting the power of Orion. Doesn't help that it wasn't intentional on Shun's part.
- Embarrassing Old Photo: Inverted. He and his family take photos of young children in a studio they own.
- Luckily, My Shield Will Protect Me: Chios Shield in Last One.
- No-Respect Guy: Gets told by Shun that he's going to be benched rather harshly. In Episode 8, Shun confesses this was due to his father telling him to do so, and he felt remorse when he saw how this took a toll in Miura's sanity.
- The Power of Love: His love for Mari helps him overcome his addiction to the Orion Switch.
Tamae Sakuma/Chameleon Zodiarts
Tamae Sakuma/Chameleon Zodiarts
Portrayed by: Maria Yoshikawa
- Easily Forgiven: Miu forgives her for becoming Chameleon, and hopes to see her work hard when they run for the Queen Festival next year.
- Jack of All Stats: The stretchy tongue and invisibility give her a better edge than most Zodiarts, but not enough to outmatch Fourze's arsenal.
- Multipurpose Tongue: She can use her Chameleon Overly-Long Tongue as a whip.
- Shout-Out Theme Naming: To the Tama siblings and Ken Sakuma, characters in Kamen Rider V3.
- Villainesses Want Heroes: When she returns, it turns out she wants to ask Gentaro to the prom.
Fumihiro Nitta/Unicorn Zodiarts
Fumihiro Nitta/Unicorn Zodiarts
Portrayed by: Kiyotaka Uji
- Cool Sword: Longsword Monarch.
- False Friend: JK pretends to be friends with Nitta so that he can use him.
- Game-Breaking Injury: Thanks to JK using him as a Human Shield, he got a bad injury on his right arm and thus was forced to miss out on a fencing tournament. This, coupled with him overhearing that he was simply used, fuels his hatred against JK. It's ultimately subverted as he's not only recovered, but well enough to augment the power of his Switch.
- Human Shield: What JK made him to be in the past against a bunch of bullies. This fuels his rage against him.
- Lightning Bruiser: Hard to hit, pretty speedy, and the rapier is pretty useful when regular attacks won't cut it.
- Master Swordsman: Justified - the Switch evolved in reaction to his training in fencing.
- Unicorn: Obviously.
Teruhiko Satake/Hound Zodiarts
Teruhiko Satake/Hound Zodiarts
Portrayed by: Ryuji Sato
- Chain Pain: Both in human form (only for the symbolism though) and Zodiarts form.
- Foil: He and Shun both have overbearing fathers; they only differ in actions - whereas Shun was driven into a breakdown but eventually found friends, Teruhiko decided to bust the chains out and act like a rebel.
- Freudian Excuse: Conveniently mirroring Shun during #7-8.
- Jack of All Stats: His two attacks are great for long and mid-range opponents. Unfortunately, most of the time he is able to escape due to something else happening (ie Scorpio helping him or Shun stopping Fourze from defeating him). Once Fourze had him in the open, he was done.
- Japanese Delinquents: At home, anyway.
- Living a Double Life: JK's intel reveals that at school he plays The Dutiful Son and student; after school, however, he became a petty thief stealing chain-like jewelry, using them as his weapons and also to symbolize his desire to break free from his father's shadow.
Ritsuko Usaka/Altar Zodiarts
Ritsuko Usaka/Altar Zodiarts
Portrayed by: Hikari Kajiwara
- Freudian Excuse: Reveals that she's already sick of being ostracized because she can see things others couldn't, and getting blamed by teachers for any supernatural mishap she witnesses.
- Hoist by His Own Petard: Tries to beat Fourze using her head of fire...but his Fire States makes him able to absorb her attacks, thus rendering them useless.
- Mirror Character: With Tomoko - both have ESP, as shown in a flashback when they first meet, as both of them reach for the same book. The glaring difference between their fates gets lampshaded below.
- Magic Staff: Aradia Staff which produce fire and have psychokinetic ability.
- Mighty Glacier: Doesn't move a lot and uses her levitation to get an advantage on her opponents. Her fire attacks are very powerful though...until Fourze absorbed it and sent it back at her.
- Pet the Dog: Despite her hatred of teachers, she liked Ms. Sonoda enough to be honest about how her presence could've saved her from the life of a witch and exhorts her to run away before she blows up the entire school. Becomes very hard to look at when you find out about what Sonoda really is 3 episodes later.
- Then Let Me Be Evil: Being treated like a freak and always being blamed for the supernatural occurences only she can see caused her to turn bad for real. She actually quotes this almost word for word.
- Villainesses Want Heroes: When she returns, it turns out she wants to ask Gentaro to the prom. She had to settle with Ryusei instead in #26.
Hiroki Makise/Pyxis Zodiarts
Hiroki Makise/Pyxis Zodiarts
Portrayed by: Takafumi Shinohara
- Beware the Silly Ones: No, really. Makise went from geeky self-absorbed dork with a crush on one girl, play-acting as the "rest" of the astronomy club "Party of One"-style, to invoking a Deal with the Devil with Yuki, turning Fourze's attacks on his friends and finally attempting to SHOVE A BUS FULL OF STUDENTS OFF A BRIDGE. And all within the sophomore year! There's also the fact that he's a complete weakling in hand-to-hand combat, the only blows he ever manages to score on Fourze being a result of pretty much just flailing his bladed arms around like a dork, but his power of being able to move things with his mind make him a threat.
- He only gets worse in the follow-up novel “Ama-High Graduation”, where he is part of a Fusion Dance to summon the Argo Zodiarts.
- Blade Below the Shoulder: Averted. Despite the way they are placed and look, Pyxis does not use them for offense. They're more like dowsing rods that happen to be sharp.
- The Bus Came Back: He comes back in #37.
- Character Tics: Has a peculiar way of holding his switch, by sticking out his index finger as though he were pointing before clicking on the switch with his thumb, often holding his hand sideways as he does this. He holds the Radar switch like this in the movie when he switches it on.
- Dirty Coward: The second his advantages are all lost, Makise tries to get the hell out of dodge. Tries.
- Dowsing Device: How the blades on his arms function. They range from having the ability to find something (by letting someone touch them and think about the item in general), or using them to control people for his own use.
- Explaining Your Power to the Enemy: He was smart enough to AVERT this; Fourze tried firing his Launcher missiles at Pyxis, not knowing of the latter's powers until it was too late, destroying what seemed to be the locker to the Rabbit Hatch in the process.
- Failed a Spot Check: Yuki never even realized he was also participating in the test until they were all inside the Isolation Chamber. Naturally, she freaks out and backs away from him.
- Four Eyes, Zero Soul: Was obsessed with Yuki for quite some time, but now that he's Pyxis he decides that it's time to crush her like (he thinks) she did to him, stating she was damaged goods. He's also the first Zodiarts to be portrayed as an unsympathetic Jerkass from the get go. What's more, he was like this before Scorpion gave him that switch!
- Hate Sink: He's a misogynistic creep and a deranged Stalker with a Crush who attempts to murder a bus full of girls just because he's biter at one of them turning him down. Tellingly, he is one of the very few villains Gentaro doesn't try to befriend after defeating them.
- He-Man Woman Hater: His stalker-like tendencies fueled this ideal. Tomoko lampshades this when he returns in #37—25 episodes later by saying, "Simply, he's a misogynist."
- I Lied: Made a deal with Yuki to find the locker if she agreed to be his girlfriend and abandon her friends. He had no intention of keeping his side of the deal and instead blew up the locker so he could see her cry.
- Jerkass: So much so that Gentaro doesn't extend his hand of friendship as he'd done with previous Zodiarts.
- Kick the Dog: Only helped Yuki find the locker for the Rabbit Hatch just so he could destroy it and make her cry.
- Knight of Cerebus: Of the Monster-Of-The-Week variety.
- Laser-Guided Karma: Becomes the first Switcher to miss out on Gentaro's friendship offer, leaving him instead to try to flee (in vain) from the girls whom he trapped on the bus at the end of Episode 12.
- Loners Are Freaks: He's the only member of the Astronomy Club, with Yuki noting that it's because of his behavior that either everyone else left the club or no one ever joined it to begin with and is shown to interact with no one else in the school. He's also a deranged stalker with aspirations to murder.
- Man Scorned: Yuki has no feelings for him whatsoever, so he made it his duty to crush her by trying to destroy the locker connecting to the Rabbit Hatch. In Episode 12, he tries to murder every other girl who shot him down by trapping them on a bus bound to drive off an unfinished bridge.
- Mind over Matter: Can control objects and people with the blades on his arms.
- Never My Fault:
- He seems completely oblivious to the fact Yuki isn't turning him down out of spite but out of repulsion over his creepy obsession with her, instead deciding that she deserves to suffer for it. This extends to the 20-30 other girls that have rejected him.
- He also claims it's Fourze's fault for seemingly destroying the locker to the Rabbit Hutch when in fact he redirected Fourze's missiles. This one's Justified as he was actively trying to torment Fourze.
- Psychopathic Manchild: Let's see, a loony kid who obsesses over Yuki but then tries to destroy her once it became clear that she's not going to reciprocate his "feelings" and takes sheer delight in turning girls into shooting stars by killing them (as evidenced by a future diary full of cute pictures depicting his gambit to send a bus full of them crashing off of an unfinished bridge)? Oh, yes. And JK's intel implies he's been like this way before he even got his Switch! The Switch just made him worse.
- Reformed, but Rejected: He seems to think he's reformed when he reappears in #37, but Yuki and Tomoko make it clear he has not been forgiven. Played straight in the movie, though, when he's one of the 40 people who activate the Astro Switches to power up Fourze and Meteor.
- Slasher Smile: Has one of these whenever he's about to transform into Pyxis.
- Squishy Wizard: He terrorizes Amanogawa with his telekinetic powers. The Zodiarts Switches' ability to mutate to suit their users' natural talents, however, leaves him in a bad spot. Whereas Miura was a football player, Sakuma a cheerleader, Nitta a fencer, Satake a brawler, and Usaka a firm believer in black magic, he's nothing but a geeky dork with serious psychological problems, leaving him an utter pushover in melee combat (one exploited by Fourze's mid-range-oriented Elek States).
- Stalker Shrine: He wasn't only obsessed with Yuki. JK found out that the guy has a star map with the names and pictures of all the pretty girls in Amanogawa that he was gong to put on a bus and make it crash off of an unfinished highway.
- Stalker with a Crush: For Yuki. He's given her incredible amounts of letters, gifts, emails and voicemails for God knows how long.
- Apparently extends to a host of other girls whom he forced onto a bus headed for an unfinished bridge.
- Took a Level in Kindness: He's a nicer person once he reappears in #37. That's about all that can be said on that front.
- Vile Villain, Saccharine Show: In a rather lighthearted series where even Gamou seems to have good intentions and every other Zodiarts is an Anti-Villain, a genuinely creepy sociopath like this guy really stands out.
Soshi Motoyama/Perseus Zodiarts
Soshi Motoyama/Perseus Zodiarts
Portrayed by: Ryutarou Akimoto
- Ax-Crazy: He was the second craziest Zodiarts next to Makise, but he's shown to be much better off at the end of Episode 16.
- Berserk Button:
- This guy really hates Yuki's voice when she sings, but has no problem with Abe and the rest of the Glee Club.
- He also hated Gentaro singing the Hayabusa song (although Gentaro might've done it deliberately to lure him out)
- Childhood Friends: Abe mentions that they went to Elementary and Middle School together. At the end of #16, they're on the rooftop shaking hands.
- Disproportionate Retribution: He's decided to turn everyone who kept him from painting in peace into stone statues. His victims are three punks who bullied him, a pitcher who accidentally knocked over some paint cans with a stray baseball, and two Gossipy Hens who, in his opinion, won't shut up. And that's not yet mentioning a building he damaged such that it will lean, because it was blocking his view of Mount Fuji.
- Freudian Excuse: Because everyone's been bugging him and not letting him paint in peace, he's become a Zodiarts to shut them up for good.
- Hair-Trigger Temper: If you do anything to interrupt his painting, he'll go berserk.
- Heel–Face Door-Slam: The first Zodiarts in the series to show redemption even in Last One stage, but Libra uses Mind Control on him to force him to fight Fourze.
- Irony: His powers get blocked when Gentaro uses the Pen Switch on him and splatters ink on his Medusa Hand.
- Mad Artist: His art is decent, but his obsession to his works is... unhealthy, to say the least. He gets much better at the end of #16, deciding to redo his Mount Fuji picture and is shown to be more calm about it.
- Manly Tears: Breaks down into these, while in Zodiarts form mind you, once he sees the works of the kindergarten class surrounding a previous work of his, and realizing that he was only trying to make himself happy with trying to perfect his painting.
- Master of None: Sure he has the sword and petrification powers, but he's nothing when they're rendered useless.
- Medusa: His left hand turns people to stone. And if Gentaro was conscious the whole time... Kengo notes that the petrification wasn't complete and that's why Gentaro was able to move around despite becoming stone. Still, doesn't necessarily mean the other victims aren't somehow conscious despite being unable to move.
- My God, What Have I Done?: Upon arriving at the kindergarten class, he's awed that his previous painting is surrounded by all of the other works of the kids, reminding him of Gentaro's drawing of Mount Fuji. He then realizes that he had taken his art so seriously that he forgot the reason he'd been making it in the first place, to make the children happy, breaking down into tears. It's also implied that this canceled out his ability to evolve into a Horoscope.
- The Perfectionist: He proclaims that anything that isn't perfect must be destroyed. Fortunately, he sees all of the kindergartners' drawings next to his old painting for them, and realizes that it doesn't matter if it's perfect or not. What mattered was the passion and love they put into them.
- Pet the Dog: Yes, he's utterly crazy and has bad anger issues, but the reason he wants to perfect his paintings is because he simply wanted to make a kindergarten class he sometimes visits happy with his works. Also, he doesn't hate all of the Glee Club; his ire is just toward Yuki and her Hayabusa song. As shown in the end of #16, he's back to being good friends with Abe.
- Secret Handshake: Shown twice; he does it with Gentaro (as Perseus) and then once more with Abe at the end.
- Taken for Granite: What frequently happens to his victims.
Kimio Nonomura/Lynx Zodiarts
Kimio Nonomura/Lynx Zodiarts
Portrayed by: Shohei Yamazaki
- Character Tics: Snapping his left thumb and index finger, which quickly outed his true identity to the Club.
- Flat Character: Aside from having a one-sided rivalry with Kengo on the smartest student in school, there's nothing else on him. Even more so since we don't even see him after Gentaro destroys his Zodiarts switch.
- Fragile Speedster: Uses his speed to his advantage, but can't take powerful hits.
- Serious Business: He knocks out the competition for smartest student in the school.
- Shadow Archetype: He's basically Kengo minus the idea of him wanting to make friends and the toleration for Gentaro's antics.
- What Happened to the Mouse?: He was last seen in the Rabbit Hutch with the KRC suggesting to put him in a storage closet. We don't even know whether or not he changed for the better.
Jin Nomoto/Dragon Zodiarts
Jin Nomoto/Dragon Zodiarts
Portrayed by: Ryu Ando
- Improvised Weapon: Throws shot puts around. Surprisingly, nobody picked up on this and said "Maybe the Zodiarts is part of the track and field club!" To be fair, they were already having trouble with Kengo and Gentaro's relationship to actually pay attention.
- Jerk Jock: To a degree that makes even pre-Character Development Shun look like a Nice Guy in comparison.
- Made of Iron: More like made of steel...Which spelled the end of his Zodiarts career when Fourze obtained Magnet States.
- Nigh-Invulnerable: It can stand the attacks from both Fire and Elec states, and Meteor can't even land a single blow on it! The "Nigh" comes into play when Fourze assumed Magnet States, then mopped the floor with Jin.
- No Social Skills: Shun notes that Jin's "not good with words" when he returns, implying this played into Jin's Zodiart stint.
- Playing with Fire: In Episode 20, he gains the ability to shoot fire.
- Shout-Out: A dragon that goes around throwing balls. The reference would only be clearer if he granted wishes.
- Took a Level in Kindness: He's still kind of a prick, but he's cooled off considerably when he appears in #25 and #26. He's even disappointed when Gentaro briefly doubts Ritsuko's still good.
- Vocal Dissonance: The some what squeaky voice that comes off the fearsome looking suit might be surprising.
Natsuji Kijima/Pegasus Zodiarts
Natsuji Kijima/Pegasus Zodiarts
Portrayed by: Soran Tamoto
- Pegasus: Self explanatory.
- Red Herring: Was thought to be Haruka. Kijima was deliberately impersonating her fighting style to set her up as said Zodiarts out of petty revenge for confiscating his fan, and For the Evulz.
- Wings Do Nothing: They're just there for decoration.
Norio Eguchi/Cygnus Zodiarts
Norio Eguchi/Cygnus Zodiarts
Portrayed by: Shugo Nagashima (live), Taiki Matsuno (voice, Cygnus Zodiarts)
- Bitch in Sheep's Clothing: Zig-zagged. At first it seems like a hero for justice...until JK reveals that Cygnus beats people up who make fun of it. Misa Toriizaki was the suspect, but when it turned out to be Eguchi, he was revealed to have a split personality, where his darker side was the one beating people up including (mentally) Eguchi for not living up to his standards. By the time he resisted going the Last One Stage, however, he get abducted and the previous Red Herring lead her group into forcing him to transform!
- Captain Ersatz: Of both Sieg and Kamen Rider IXA.
- Character Tics: Assigning people points based off of good or bad actions; Cygnus fangirl Misa Toriizaki does the same but this is just a Red Herring.
- Cosplay: Has an outfit inspired by Cygnus, and then dons one based on Fourze at the end.
- Dirty Coward: The darker personality used Tomoko as a shield to keep Meteor from bashing him in. He does it again in Episode 24, this time with Toriizaki.
- Everyone Calls Him "Barkeep": Due to his reputation as a hero, everyone simply calls him "Cygnus"; Gentaro's fight with his Last One state in Episode 24 marks the first time anyone refers to him as the Cygnus Zodiarts.
- Feather Flechettes
- Fanboy: Wanted to become a hero after observing Fourze fighting off Lynx in Episode 18 then switched to Cygnus after he was saved from thugs. He decides to go back to worshiping Fourze via dressing up like him and helping a lady on the street.
- Glass Cannon: Can beat up people with a fight and uses his feathers as projectiles, but once Meteor gives him a good kick, he goes down.
- Lady Macbeth: Became a victim of one, by Toriizaki just as his switch reached the Last One Stage.
- Paint It Black: His Perpetual Molt does this once he triggers Last One.
- Perpetual Molt: The indication that Cygnus has arrived.
- Secret Test of Character: Gentaro gets the members of the KRC to dress up and act out in situations to let Eguchi help them out. Eguchi settles on helping the little school kid (aka Yuki) get her balloon back.
- Split Personality: The first time Eguchi used the Zodiarts Switch, it caused the darker side of his personality taking control of Cygnus while the real guy remained oblivious.
Yayoi Tokuda/Coma Zodiarts
Yayoi Tokuda/Coma Zodiarts
Portrayed by: Kasumi Suzuki
, the hair of Queen Berenice II of Egypt.- Bitch in Sheep's Clothing: Seems to be a reasonable reporter...then she intentionally frames Tamae, Kimio and Ritsuko of wrongs they never committed — all because she doesn't want to graduate and neither will she let the others do so.
- Club President: Of the Newspaper Club.
- Foreshadowing: What's she doing in her first appearance? Trying to get an article out of Tamae, Ritsuko and Jin, even though it's only Ritsuko's alter-ego who "returned" around that time.
- Four Eyes, Zero Soul: She seems nice initially but she refuses to stop and ask if anyone else shares her desire to stay at AGHS forever, instead choosing to go through with her plan to force them to.
- Growing Up Sucks: Her motivation for becoming a Zodiarts and framing Ritsuko, Kimio and Tamae? She doesn't want to leave high school, and feels that neither should everybody else.
- Hypocrite: Becomes a monster because she loves AGHS and doesn't want to graduate. Yet she furiously claims Tamae, Jin, and Ritsuko don't deserve to leave after their actions as Zodiarts, apparently seeing AGHS as a punishment as well. Of course, she could also be justifying it as them being undeserving of a chance to leave the school and by proxy her.
- Informed Ability: JK claims that she makes for a better Knowledge Broker than him. At the very least, she was able to figure the identities of former monsters.
- Mirror Character: To Miu. Both are seniors, presidents of their respective clubs, and dread graduating. However, this is where similarities end: whereas Miu learns to accept the fact but Yayoi refuses to accept it.
- Mook Maker: Can turn its hair into copies of existing Zodiarts.
- Prehensile Hair: One may ask how Coma of all constellations would have any combat application as a Zodiarts. The answer is this.
- Sanity Slippage: Perhaps one of the most extreme cases of all the Zodiarts.
- Squishy Wizard: She can create clones from her hair and use it to entrap opponents, but once she's rendered immobile by the Power Dizer, she's pretty much good as done.
- Stringy-Haired Ghost Girl: Provides the inspiration for this Zodiarts. Not just for the stringy hair and deliberately creepy Limp and Livid portrayal, but Yayoi also harbors a grudge.
- What Happened to the Mouse?: We don't know if she even graduates or gets held back like she wanted to.
Haru Kusao/Musca Zodiarts
Haru Kusao/Musca Zodiarts
Portrayed by: Jigen Araki
- Berserk Button: Due to the Switch, he lashes out at Ran on her insistence on always trying to protect him or whenever she tries to say he doesn't have to get stronger because she'll protect him.
- Detachment Combat: Can separate into a swarm of flies to annoy Fourze.
- Dull Eyes of Unhappiness: Has serious bags under his eyes as he uses the Switch more and more.
- How Do I Shot Web?: A rare villainous example. Not only is he a first time Switcher still getting used to his new form, his Switch is evolving, continually dumping new powers on him.
- Lethal Joke Character: Considering that he starts out as a wimp, and gets a simplistic Zodiarts design that's little more than a glorified Mook with a pathetic housefly Animal Motif, his sudden rush of powers really comes out of nowhere.
- Only Friend: Ran is his only friend even though he actually wants to be friends with Gentaro. Ran is pretty much the sole reason that Haru even became a Zodiarts in the first place and ironically the reason that he gets worse.
- Power Gives You Wings: Once he reaches Last One.
- Protectorate: Deconstructed in that his desire to change is ousted by his overprotective friend, frustrating him.
- Sanity Slippage: The most extreme non-Horoscopes example. His mental slide is so bad that beating him without doing something to rectify his state of mind before deactivating his switch would likely destroy his mind.
- Shrinking Violet: Doesn't help that he has a pushy girl friend like Ran.
- Sixth Ranger: During the finale, Haru finally becomes a member of the Kamen Rider Club with Ran.
- Took a Level in Badass: Is noteworthy in that his Switch is evolving even before he hit Last One.
