Kamen Rider Fourze/Characters/Zodiarts

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

 * 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.
 * 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.
 * Virgo invokes this with deliberately bird-like wings that even shed feathers.
 * Inverted with the Dragon Zodiarts - 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.
 * 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.
 * Episode 14 reveals that when a former switcher is given a new switch, it immediately enters Last One state.
 * Episode 15 reveals that a Zodiarts can surpass the Last One state, which could lead to them becoming a Horoscope.
 * 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 Zodiarts) - develops withdrawal symptoms after his Switch is destroyed.
 * From Nobody to Nightmare: Invoked in the same way as Kamen Rider Double.
 * 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.
 * Mono-Gender 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 Zodairts refrain from speaking, have their voices digitally distorted, or a separate voice actor is used until their identity is revealed.
 * Magic and Powers
 * Personality Powers: The Zodiarts evolve in reaction to their host's abilities and desires. For example the Unicorn Zodiarts gained a sword due to Nitta's fencing ability and Hound fit Teruhiko's fondness for chains as its main weapon.
 * Monster of the Week
 * One-Winged Angel: Some of the "Last One" transformations.
 * Taken beyond eleven in #14
 * Shout-Out
 * Lynx Zodiarts, 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
 * Stock Super Powers
 * Super-Powered Evil Side: The Zodiarts are pretty much extensions of their anger and wrath, but sometimes they can get even worse. Case in point:
 * Weapon of Choice: Some of the Zodiarts have one. These are: Orion, Monoceros, Altar, Perseus (regular) Libra, Virgo and Aries (Horoscopes)
 * Named Weapons: All of them are named. The Other Wiki shows their names.
 * Villainous Breakdown: Apparently the most effective way to accelerate a Switch's evolution to its "Last One" stage.
 * Villainous Breakdown: Apparently the most effective way to accelerate a Switch's evolution to its "Last One" stage.

The Red-Eyed Man | Mitsuaki Gamou
"Live Actor: Shingo Tsurumi"

Founder of Amanogawa High School, chairman of the board, and former scientist and pioneer of lunar research with connections to NASA and the Russian Federal Space Agency.

He is secretly the mastermind behind the Zodiarts, and has been distributing the Zodiarts Switches amongst the students of his school for reasons unknown. His eyes often glow with an unearthly red light, and he possesses the ability to wield Cosmic Energy in a raw form.

""He was having a little fun.""
 * Affably Evil: Is the Big Bad, but seems to be a geuninely nice guy.
 * Ambiguously Human: He looks human, but the red eyes that light up and apparent control over the Zodiarts implies he's not.
 * Big Bad: Appears to be the ringleader of the Zodiarts thus far.
 * Evil Overlooker: the newest version of the OP (#35 on) shows him alongside the Horoscopes in this manner.
 * Evil Teacher
 * Hidden Agenda Villain: There has been little explanation as to why he is distributing the Zodiarts Switches. So far, it is hinted that he is attempting to awaken a greater power by distributing the Switches to children, who are more charged with emotion and thus more likely to evolve the Switches beyond their original specifications.
 * It Amused Me: Hayami mentions that this is why there was a "bonus question" in the astronaut qualification test.

 * It Amused Me: Hayami mentions that this is why there was a "bonus question" in the astronaut qualification test.


 * Jedi Mind Trick: How he got.
 * No Name Given/Only Known by Their Nickname: Initially, as "The Red-Eyed Man".
 * Orcus on His Throne: He's mostly been seated on his chair and talking to the Zodiarts.
 * Pet the Dog/Pragmatic Villainy: For a toku villain, he seems unusually committed to having his minions not die. He chooses to send those that repeatedly fail him to the Dark Nebula, and he makes an effort to have Virgo rescue those who are taken out by Fourze in space.
 * Red Eyes, Take Warning
 * Well-Intentioned Extremist: If Scorpion is to be believed, he's apparently trying to benefit mankind.

Horoscopes
A group of twelve Zodiarts, each representing a constellation of the Western Zodiac. They are direct subordinates to Gamou, giving out Zodiarts Switches on his behalf, and are notably stronger than regular Zodiarts. A Horoscope can be identified by the distinctive black robes they wear, which act as Power Limiters to their true potential.

A Horoscope is created when a Zodiarts exceeds the Last One stage of the Zodiarts Switch, reabsorbing its human body and evolving into an even more powerful form. Only certain talented individuals have the potential to become a Horoscope; thus, it is the Horoscopes' mission to find and awaken all twelve of their kin.


 * Badass Long Robe
 * Co-Dragons
 * Deadly Upgrade: Kengo's scan of Scorpion Nova implies the supernova power up may be carry some risk to the Zodiarts itself.
 * Five-Bad Band: The initial Horoscopes fit into this fairly well, even though they are not all active at once.
 * Big Bad: The Red-Eyed Man/Mituaki Gamou
 * The Dragon: Virgo Zodiarts
 * Evil Genius: Libra Zodiarts
 * The Brute: Leo Zodiarts
 * Dark Chick: Scorpio Zodiarts
 * I Am Not Left-Handed: According to offical materials, their robes limit their power to some degree and casting them off allows them to fight at full power.
 * One-Winged Angel: The Red-Eyed Man can give them this ability by infusing them with a "supernova". It's stated only the Horoscopes can do this.
 * The Horoscopes are pretty much One-Winged Angel forms themselves, being the result of someone who exceeded Last One and evolved into them. It doesn't even have to be one of the twelve Western Zodiac signs, as
 * It Gets Worse.
 * Standard Evil Organization Squad
 * Western Zodiac

Scorpion Zodiarts/
"Voice Actor: Eiji Takemoto"

The Zodiarts representing the constellation Scorpius, the Scorpion. It is the first of the Horoscopes to be seen, and distributes Zodiarts Switches to those who wish to gain revenge. In battle, it uses powerful kickboxing attacks.


 * Absurdly Sharp Stinger: The stinger can pierce through the bottom of a metal trolley.
 * Beware My Stinger Tail: It has an extendable scorpion tail on its head that can inject a deadly poison into whoever it stings.
 * Big Creepy-Crawlies
 * Death by Irony:
 * Extremity Extremist: Doesn't rely on its hands at all during combat, preferring either its legs or Stinger Tail
 * Has now become somewhat of a Bare-Fisted Monk, what with more common usage of the hands in combat, though will still prefer the legs.
 * It's Personal: Seems to be his preference as to whom he hands out Zodiarts Switches. Which is in line with both myths of Scorpius, where the Scorpion was sent to kill Orion due to a god (Apollo in one and Gaea in another) being offended by him.
 * Jack of All Stats: Great at attacking with its bare fists and feet and pretty much sends Fourze flying in almost every battle they have.
 * One-Winged Angel:.
 * From what Gamou says,.
 * Red Eyes, Take Warning
 * Scary Scorpions
 * Starter Villain: Is the first Horoscope to show up and Fourze's first real challenge, but was beaten without even a Mid-Season Upgrade, and was considered in universe to be incompetent picking Switchers.
 * This Cannot Be!:
 * Villain Exit Stage Left: Tends to do this when Fourze is coming close to victory.
 * Villain Forgot to Level Grind: Its problem wasn't getting weaker, but Fourze was getting stronger and it wasn't. It had to be given its One-Winged Angel, as opposed to all the other Horoscopes who got theirs without help.
 * Villainous Breakdown:
 * With My Hands Tied: Maybe not on purpose, but it doesn't even bother using its hands in its first fight with Gentaro.
 * You Have Outlived Your Usefulness: Subverted.
 * Villain Exit Stage Left: Tends to do this when Fourze is coming close to victory.
 * Villain Forgot to Level Grind: Its problem wasn't getting weaker, but Fourze was getting stronger and it wasn't. It had to be given its One-Winged Angel, as opposed to all the other Horoscopes who got theirs without help.
 * Villainous Breakdown:

 * You Have Outlived Your Usefulness: Subverted.

Libra Zodiarts/
The Zodiarts representing the constellation Libra, the Scales of Justice. The second of the Horoscopes to appear, it possesses various powers of illusion and fights using a Khakkhara shakujo. It only distributes Zodiarts Switches to those it feels have the potential to become Horoscopes, and personally mentors them to reach that point.


 * The Bad Guy Wins:
 * Bare-Fisted Monk: It should be noted that he seldom actually uses that staff when he fights in one of his disguises.
 * Dragon with an Agenda:
 * Evil Genius: Amongst the Horoscopes, this seems to be his role. He is more manipulative and cunning than his comrades, and has found himself in the role of distributing Zodiarts as part of Gamou's master plan.
 * Evil Mentor: How he goes about dealing with his prospect Zodiarts and . The Zodiarts he "mentors" even refer to him as "Master Libra".
 * The Force Is Strong with This One:
 * Foreshadowing: in #37, he thinks that the astronaut exam is a good way to spot new potential Horoscopes.
 * Kick the Son of a Bitch:
 * Knight of Cerebus: Right after Makise is dispatched, this guy sealed the deal on the Cerebus Syndrome.
 * Manipulative Bastard
 * Master of Illusion: He possesses several illusory powers, most notably the ability to make itself and others look like other people. At one point he even fights Fourze while disguised as a second Fourze.
 * Master of None: He doesn't have a lot of fighting capability and his illusion powers are only good for distraction.
 * Pragmatic Villainy: really takes his role as a mentor to prospective Zodiarts seriously, but, of course, this only ties into the Horoscopes' goal of completing their roster. His abhorrence towards Cancer also counts, since he believes the latter to be too much of a loose cannon anyway.
 * Red Oni, Blue Oni: The blue to /Cancer and Yamada/Aries' red.
 * Shock and Awe: Can deliver a blast of electricity from his forehead.
 * Simple Staff: Wields one that resembles a Khakkhara shakujo, complete with jingling rings.
 * Smug Snake/Smug Super: It's becoming clear that he gives himself too much credit for being "Master Libra" and thinks he's more important within the Horoscopes than he really is. Overlaps with his frustrations that he's turning into The Unfavourite, while Gamou gives more leniency.
 * He starts to become even more smug after obtaining the Eye of Laplace, not hesitating to brag about it in Leo's face.
 * Villain Exit Stage Left: Is able to teleport, leaving behind a blue nebula like light when he does so.
 * Villainous Breakdown:

Virgo Zodiarts
"Voice Actress: Rie Tanaka"

The Zodiarts representing the constellation Virgo, the Virgin Goddess Astraea. The third Horoscope to appear, she has various powers of spatial manipulation, such as the power to imprison people in a Pocket Dimension called the Dark Nebula. She first appears fighting against Fourze in Movie War Megamax.


 * An Axe to Grind: Wields a staff-like axe.
 * The Dragon: While first Scorpion and then Libra served this role directly, Libra's description of her implies she's closer to this role the the first two.
 * Early-Bird Cameo: Rather like Meteor, she appears in Movie Wars Megamax before debuting at the end of #18.
 * Flash Step
 * Pocket Dimension: The Dark Nebula.
 * Power Floats
 * Power Gives You Wings
 * Power Levels: She states in #32 that Fourze's Cosmic States makes him almost equal to her in strength.
 * Power of the Void: Don't believe me? In her tussle with Meteor in #22, she fired spheres of energy that would have possibly killed Meteor had he not move. Why? Because one kind of energy sphere Virgo can fire are black holes.
 * Rose Haired Zodiarts
 * The Smurfette Principle: Currently the only Horoscope that's clearly female.
 * Sphere of Destruction
 * Stationary Wings
 * Stone Wall: Prefers to utilize a very defensive fighting style, and can use her wings as a shield.
 * Unless she taps into the power of Movie Wars Megamax's budget, whereupon CGI wings and Wire Fu turn her into an outright Lightning Bruiser.
 * Thinking Up Portals: Has the ability to create portals into space, much like Fourze's Cosmic States, as well as teleport people into the Dark Nebula.
 * Winged Humanoid

Cancer Zodiarts/
The Zodiarts representing the constellation Cancer, the Crab sent to distract Heracles from his tasks. The fourth Horoscope to appear, it possesses an incredibly tough skin that makes it hard to damage and sharp pincers that can slice through anything. It evolved from the Zodiarts.


 * Absurdly Sharp Claw: His open claw is even capable of cutting through Fourze's shield, which is made of a super-durable metal called Astorium.
 * Dangerously Genre Savvy:
 * Deadly Game:
 * Devil in Plain Sight
 * Faux Affably Evil: The fact he's polite and cheery just makes him more disturbing.
 * For the Evulz: How he approaches students with Switches. He basically asks if they want to have fun.
 * Made even worse in #27.
 * Fireballs: One of his abilities.
 * Giant Enemy Crab:
 * Ham-to-Ham Combat: One-sided, actually. During his fight with Meteor in #27, he would not shut up.
 * Hoist by His Own Petard: He would free the souls of the KRC he imprisoned should one make him laugh..
 * Another thing that really bites him in the ass was
 * Irony: Cancer was supposed to pinch at the toes of Hercules while Hercules battled the Hydra. Hercules squashed him pretty easily. Here, Cancer's been really hard to destroy due to his powerful armor and the fact that he runs away just before Gentaro puts the finishing blow on him.
 * Kill It with Fire: Thus far the only thing capable of damaging him.
 * Until #28, that is.
 * Laughably Evil: Seems to be an intentional tactic of his to get under his opponents skin and confuse them. Makes him even more disturbing when he does stuff like.
 * Lightning Bruiser: Fast, strong and takes most hits without a scratch on his shell.
 * Making a Splash: Another of his abilities.
 * One-Winged Angel:
 * Psycho for Hire: Unlike the other Horoscopes who seem to be Well Intentioned Extremists, Cancer is just a Sociopath who enjoys what he does.
 * Red Oni, Blue Oni: The red to /Libra's blue. (One of two)
 * Sixth Ranger: His role amongst the Horoscopes. The first to surpass Last One and become a Horoscope since Scorpio, he was also responsible for dishing out The Worf Effect for a good while before his enemies one-upped him.
 * Shadow Archetype: As stated before, Cancer is one to Ryusei/Meteor. This was even Lampshaded by Cancer in 27. The parallels between the two of them are drawn constantly, with Ryusei even being the one to
 * Super Toughness: And how! He's basically immune to everything that Fourze can throw at him, except for prolonged exposure to fire.
 * We Can Rule Together:
 * Xanatos Gambit:
 * You Fight Like a Cow: mostly in his battle against Meteor.
 * You Fight Like a Cow: mostly in his battle against Meteor.

Aries Zodiarts/Tatsumori Yamada
"Live Actor: Kazuma Kawahara"

The Zodiarts representing the constellation Aries, the Ram with the Golden Fleece. The fifth Horoscope to appear, he can control the mental facilities that regulate sleep, tranquillising those who resist his will. His alter-ego is Tatsumori Yamada, a transferee to Subaruboshi from Amanogawa.


 * Astonishingly Appropriate Appearance: Well of course the Zodiarts that controls sleep would be the one that's a sheep.
 * Convenient Coma: He can induce this upon anyone else.
 * The Dreaded: Among Subaruboshi students.
 * Early-Bird Cameo: in #30, after Meteor's brief altercation with Libra at Subaroboshi, someone in an Amanogawa uniform ominously walks past.
 * Expy:
 * Irony:
 * Meaningful Name: The kanji in his name mean "dragon" and "guard/protect." In Greek mythology, Aries was a sacred golden ram whose fleece was guarded by a dragon.
 * New Transfer Student: To Subaruboshi High.
 * Pet the Dog: Bastard that he is, it's still worth mentioning that
 * Red Baron: He's known as the "Apostle of Sleep".

Leo Zodiarts/Kou Tatsugami
"Live Actor: Kazutoshi Yokoyama"

The Zodiarts representing the constellation Leo, the Nemean Lion. The sixth Horoscope to be formally introduced in the television series, although he is featured in the opening title sequence and made a few non-speaking cameos beforehand. He is a proficient and deadly fighter. His true identity is Kou Tatsugami, Gamou's bodyguard.


 * Badass: In his first scene alone he tosses the walnuts he carried in his hand into the air, beat down members of Foundation X demanding Gamou to hand over his research papers, put one in an arm hold and caught those walnuts into his hands.
 * Badass Long Hair
 * Berserk Button: He flipped after Gentarou approached Gamou without a regard for the latter's position. Gamou even held him back to make him keep his cool, but that didn't stop Leo from delivering a No-Holds-Barred Beatdown to Fourze unprovoked later.
 * The Brute: Compared to its fellow Horoscopes Zodiarts. He's also the naturally tallest of the bunch.
 * Character Tics: Manipulates walnuts in his hands, similar to Baoding Balls.
 * Death Glare
 * Dragon Their Feet: As of Episode 32, we've seen Fourze gain five powerups, three Horoscopes have been lost, yet this guy has yet to act in any fashion. Justified with his role as Gamou's bodyguard, instead of handing out Switches like Scorpio, Libra, and Cancer, an executioner like Virgo, or just fooling around like Aries.
 * Dragon with an Agenda:
 * Early-Bird Cameo
 * The Juggernaut: Thus far has been pretty much unstoppable to everything thrown at him, including both Fourze Cosmic States and Meteor Storm, and having the power to go with it.
 * King of Beasts
 * Make Me Wanna Shout: Has a powerful roar that can cause shockwaves.
 * Meaningful Name: His family name sounds similar to tategami, meaning "mane", while the kanji used for his first name means "roar."

 * More Teeth Than the Osmond Family
 * Wolverine Claws
 * You Have Failed Me:
 * You Have Failed Me:

Capricorn Zodiarts/Toujiro Goto
"Live Actor: Ryousuke Kawamura"

The Zodiarts representing the constellation Capricorn, the sea goat. The seventh Horoscope to appear, he can freely manipulate sound to his advantage. He's a student who turns out to be an old friend of JK's and wishes to reform their old band to become superstars.


 * Anime Hair: His is all spiked up.
 * Anti-Villain: Type IV. He's the least malevolent of any of the Zodiarts so far, and really just wants to play music rather than hurt anyone. He initially only fights because Fourze attacks him first.
 * Cut Lex Luthor a Check: He becomes Capricorn so he can further his music career.
 * Dreadful Musician: In human form, but not in Zodiarts form.
 * Magic Music: Can create Music Staffs to entrap his opponent, or entrance them.
 * Meaningful Name: "Goto" sounds like the Japanese pronunciation of "goat".
 * Shout-Out Theme Naming: And it's turned into his old nickname by shortening further till it's read roughly like GOD, antagonist organisation to Kamen Rider X - which JK was named for.
 * Musical Assassin
 * The Power of Rock
 * Spoony Bard: His only weapon is his guitar which is only used to blast a Musical Staff to ensnare his opponent. He doesn't use the music to brainwash his opponents (Ryusei notes that both he and Gentaro are immune to his song due to being shielded by Cosmic Energy) nor actually use it to his advantage (say, make the rave zombies to shield him so that the Riders can't touch him), and once Cosmic States captured the music he played, he had nothing left in his arsenal.
 * It's this even outside of battle; when he plays his guitar the power of the Zodiarts Switches intensify. Moreover, the only reason he gets the power of Supernova was so that he
 * Squishy Wizard: Like Aries above, he only uses his guitar as a means of attacking. Once Fourze ensnared him with his own music, he was done for.
 * We Used to Be Friends: With JK.
 * Squishy Wizard: Like Aries above, he only uses his guitar as a means of attacking. Once Fourze ensnared him with his own music, he was done for.
 * We Used to Be Friends: With JK.

Aquarius Zodiarts/Erin Suda
The Zodiarts representing the constellation Aquarius, the Water-Bearer. The eighth Horoscope to appear, she is able to use Cosmic Energy to heal herself. Erin is revealed to want to pass the mock space exam to become an astronaut like her father and will not let anyone stand in her way...not even Genki Girl and her rival, Yuki Jojima.


 * The Ace: Transfer student from America who is smart, athletic and super-hot as JK puts it. This is even lampshaded with the letter A on her chest in regards with the exam.
 * Anti-Villain: Another Type IV. Her first order of business as a Zodiarts was to heal Kengo, and she's only hostile to Gentaro because of his friendship with Yuki.
 * Book Ends:
 * But Not Too Foreign
 * Dark Chick: Apart from Virgo, she is the only Horoscope that is obviously female in appearance.
 * Death Glare: Has this down to a fine art.
 * Expy: Let's see. Serious Business about something? Check. Hates Genki Girl Yuki but doesn't have qualms with everyone else? Check. Has a Pet the Dog moment despite being a Zodiarts? Definitely. Gets talked to by Gentaro and immediately has a My God, What Have I Done? moment shortly thereafter? Yep. She's pretty much the Horoscope version of Motoyama (Perseus Zodiarts).
 * Foil: To Yuki. Where Yuki is hyperactive, loud and energetic, Erin is calm, quiet and still. Where Yuki believes in praying to the "Rocket Gods" and miracles, Erin believes in using skill to get what a person wants. Where Yuki tries to lift everyone spirits by being goofy, Erin tries to shut it down by being reasonable.
 * Green-Eyed Monster: To make a long story short, she despises Yuki Jojima. More specifically, she hates Yuki Jojima due to the resemblance of a person who took her father's spot in going into space.
 * Hair-Trigger Temper: Anything that comes out of Yuki's mouth makes her panic and crazy;
 * Healing Factor: Her water jugs on her shoulders can heal anything...even a Cosmic States Limit Break!
 * I Gave My Word: She made a promise to Gentaro that she'd give a fair fight to Yuki during the exams.
 * Making a Splash: Except her water gimmick acts as a Healing Factor, and she attacks with that nasty cat-o-nine-tails thingy.
 * Malaproper: She has a hard time pronouncing some Japanese sayings, such as proclaiming that she is "filthy" instead of "flawless" in Zodiarts form ; that's how Gentaro figured out Erin was Aquarius. It even goes to the point that the Zodiarts have to correct her pronunciation.
 * Meaningful Name: Her name is an anagram of Eridanus, a mythical Greek river that is somewhat associated with Aquarius.
 * My God, What Have I Done?:
 * Not So Different: Even though she won't admit it, she is actually similar to Yuki. Both wish to go to space, and both are determined to do the best of their abilities. It's just that their ways of leading (where Erin immediately takes charge and tells them what to do and Yuki just suggests something and presses on knowing that people will despise her for doing so) that are huge contrasts.
 * Pet the Dog: The first thing she does as Aquarius Zodiarts? Use the water from her healing jugs to heal Kengo.
 * Despite being cold to Yuki, she also praises at how Gentaro and Kengo have the potential to become astronauts.
 * Serious Business: Going into space and passing the mock space exam is very important to her, since her father never had a chance to go. Thus while she is nice to Gentaro and Kengo, she utterly despises Yuki because she doesn't believe the Genki Girl is taking the whole thing seriously.
 * Stone Wall: That Healing Factor of hers makes it near impossible for her to be defeated. But if you can destroy both the water jars on her shoulders at once, she's done for.
 * Whip It Good
 * Worthy Opponent: Considers Kengo and Gentaro these in the astronomy exam. Yuki, on the other hand is the exact opposite.

Taurus Zodiarts/Sugiura Yuuta
The ninth member of the Horoscopes to appear, he is based off of Taurus, the Bull. He was present for the mock space exam, though he was later revealed to have the potential to become the Taurus Zodiarts. An avid golf player, who forces people to sign contracts with him, and the loser is banned from interfering with the winner in any way.


 * Chekhov's Gunman: At first, he seems to have just been there for the exam. At the end of the episode, though, Libra reveals that Sugiura is going to be the Taurus Zodiarts.
 * Deal with the Devil: Seems to be his MO when dealing with potential threats.
 * A Load of Bull

Toshiya Miura/Orion Zodiarts
"Live Actor: Masanori Mizuno"

A member of the football club who, fed up with his peers' poor treatment of him, accepts the Orion Zodiarts Switch to get revenge. His patron constellation is Orion the Hunter.

 * Carry a Big Stick: The Lemnos Club in Last One
 * Defeat Means Friendship: Gentaro extends his hand of friendship to him.
 * The Dog Bites Back: The part of his Freudian Excuse for accepting the power of the Orion Zodiarts. 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.
 * Mighty Glacier: Large, imposing, and powerful. Pretty much made to beat the ever-loving crap out of people.
 * "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.
 * In Episode 13 he still hasn't forgiven Shun, despite the latter making a genuine effort to set things right.
 * The Power of Love:
 * In Episode 13 he still hasn't forgiven Shun, despite the latter making a genuine effort to set things right.

Tamae Sakuma/Chameleon Zodiarts
"Live Actor: Maria Yoshikawa"

A third-year and member of Miu's cheerleading trio, whose disillusionment with Miu's two-year winning streak at the Queen Festival drove her into accepting the Chamaeleon Switch. Her patron constellation is Chamaeleon the Chameleon.


 * The Cheerleader
 * Easily Forgiven: Miu forgives her for becoming the Chameleon Zodiarts, and hopes to see her work hard when they run for the Queen Festival next year.
 * Green-Eyed Monster
 * Invisibility
 * 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.
 * Overly Long Tongue
 * Shout-Out Theme Naming: To the Tama siblings and Ken Sakuma, characters in Kamen Rider V 3.
 * The Starscream
 * Villainesses Want Heroes: When she returns, it turns out she wants to ask Gentaro to the prom.

Fumihiro Nitta/Unicorn Zodiarts
"Live Actor: Kiyotaka Uji"

Driven by vengeance, he accepts the Unicorn Switch. His patron constellation is Monoceros the Unicorn.


 * 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.
 * Implausible Fencing Powers: Justified - the Switch evolved in reaction to his training in fencing.
 * Lightning Bruiser: Hard to hit, pretty speedy, and the rapier is pretty useful when regular attacks won't cut it.
 * Unicorn: Obviously.

Teruhiko Satake/Hound Zodiarts
"Live Actor: Ryuji Sato"

A second-year and son of the notoriously ruthless detention teacher, Takashi, who has decided to rebel against his strict father. Along the way he receives the Hound Switch, and soon goes on a rampage. His patrion constellation is Canes Venatici the Hunting Dogs.


 * Black Sheep
 * Blade Below the Shoulder
 * Chain Pain: Both in human forma and Zodiart form.
 * Freudian Excuse: Conveniently mirroring Shun during Episodes 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.
 * Not So Different: 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.
 * Spikes of Villainy

Ritsuko Usaka/Altar Zodiarts
"Live actor: Hikari Kajiwara"

A leader of a witches' coven that comprises Yuri Kuramochi, Masami Okamura and herself. As the Altar Zodiarts she uses her powers to make it appear that her group has magical powers. Her patron constellation is Ara the Altar.


 * Broken Pedestal: for Tomoko.
 * 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.
 * Goth
 * 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.
 * Not So Different: 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...until Fourze absorbed it and sent it back at her.
 * Mind Over Matter
 * Pet the Dog: Despite her hatred of teachers, she liked Sonoda-sensei 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.
 * Playing with Fire/Fireballs
 * Psychic Powers: Claims joining the witches coven with give you them..
 * Skunk Stripe: Has a streak of blonde hair.
 * 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.
 * Wicked Witch: Or so the Altar Zodiarts' power allows her to.

Hiroki Makise/Pyxis Zodiarts
"Live Actor: Takafumi Shinohara"

Yuki's former "friend" at the Astronomy Club who has a massive crush on her. Uses his Zodiarts power as a way to get to her and then extract his revenge. His patron constellation is Pyxis the Mariner's Compass.


 * Adorkable: Averted. He's a geeky dork with glasses, but he's also a psycho who could kill anyone and stalk any girl he wanted.
 * 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!
 * Blade Below the Shoulder: Averted. Despite the way they are place and look, Pyxis does not use them for offense.
 * Dirty Coward
 * 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 Dangerously Genre Savvy enough to AVERT this;
 * Failed a Spot Check:
 * Four Eyes, Zero Soul: Was obsessed with Yuki for quite some time, but now that he's the Pyxis Zodiarts 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 Zodiarts gave him that switch!
 * He-Man Woman Hater: His stalker-like tendencies fueled this ideal. Tomoko lampshades this  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.
 * 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:
 * Loners Are Freaks: He's the only member of the Astronomy Club (Yuki notes that it's because of his behavior that everyone left), and is shown to interact with no one else in the school. Oh and he's a stalker, that should explain everything.
 * 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. Taken Up to Eleven in Episode 12 when.
 * Mind Over Matter: Can control objects  with the blades on his arms.
 * Never My Fault: 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 (apparently) destroying the locker to the Rabbit Hatch (when in fact he redirected Fourze's missiles).
 * 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 ? Oh, yes. And JK's intel implies he's been like this way before he even got his Switch!
 * 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.
 * Stalker with a Crush: For Yuki. He's given her incredible amounts of letters, gifts, emails and voicemails for God knows how long.
 * Teens Are Monsters: He's the worst out of all of the  Zodiarts shown so far and that's saying something!
 * Two Episode Wonder: Despite just being another Monster of the Week, the fact that his entry is twice the length of any other Zodiarts and he's got an entire section in the Fridge Horror entry shows how much of an impact this psycho has made in the show.
 * 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.
 * Teens Are Monsters: He's the worst out of all of the  Zodiarts shown so far and that's saying something!
 * Two Episode Wonder: Despite just being another Monster of the Week, the fact that his entry is twice the length of any other Zodiarts and he's got an entire section in the Fridge Horror entry shows how much of an impact this psycho has made in the show.

Soushi Motoyama/Perseus Zodiarts
"Live Actor: Ryutarou Akimoto"

President of the Art Club. He takes the Perseus Switch so he can dish out some punishment upon anyone (and anything) that disturbs his work. His patron constellation is Perseus.


 * 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. So far 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.
 * Irony: His powers get blocked when Gentaro uses the Pen Switch on him and splatters ink on his Medusa Hand.
 * Well it has been said that the pen is mightier than the sword.
 * 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
 * Kengo notes that
 * Monster Based on a Hero Prefers Swords: The Oracle Sword.
 * 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.
 * 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.
 * Serious Business: Painting
 * Secret Handshake: Shown twice; he does it with Gentaro (as Perseus Zodiarts) and then once more with Abe at the end.
 * Super OCD: 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.
 * Taken for Granite: What frequently happens to his victims.

Kimio Nonomura/Lynx Zodiarts
"Live Actor: Shohei Yamazaki"

Kengo's self-proclaimed rival, who was given his Switch by the Libra Zodiarts. He uses it in order to get rid of the competition of all students with higher test scores than he. His patron constellation is Lynx the Lynx.


 * 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.
 * Panthera Awesome
 * Shadow Archetype: He's basically Kengo minus the idea of him wanting to make friends and the toleration all of Gentaro's antics.
 * Small Name, Big Ego: It comes with being Kengo's "self-proclaimed" rival.
 * The Rival: Claims to be this for Kengo.
 * 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.
 * Wolverine Claws: Comes in hand with his feline theme.

Jin Nomoto/Dragon Zodiarts
"Live Actor: Ryu Ando"

Captain of the Track and Field team who became a Zodiarts to discourage outside help and to kill the Kamen Riders, starting to grow bored of track practice. His patron constellation happens to be Draco the Dragon.


 * Feed It with Fire: and Electric, too!
 * For the Evulz: Why he went about and became a Zodiarts.
 * 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.
 * Mighty Glacier: He can take hits hard. REALLY hard. He can also strike back really hard.
 * 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.
 * Our Dragons Are Different
 * Playing with Fire: In Episode 20, he gains the ability to shoot fire.
 * Shout-Out: A dragon that goes arround throwing balls. The reference would only be clearer if he granted wishes.
 * Vocal Dissonance: The some what squeaky voice that comes off the fearsome looking suit might be surprising.

Natsuji Kijima/Pegasus Zodiarts
"Live Actor: Soran Tamoto"

A Zodiarts who is attacking talented martial artists to test its own strength. Its patron constellation is Pegasus.


 * Beneath the Mask: A very jolly fellow who sprinkles rakugo phrases and puns into his normal speech.
 * Blood Knight
 * Character Tic: Clops his feet like a horse when about to throw a high kick.
 * Nowadays he's more often seen tapping that fan of his in time with the dialogue.
 * Disproportionate Retribution: Part of the reason why he, though he admits he would've done it to someone anyway and that was just why he did it the way he did.
 * Faux Affably Evil
 * For the Evulz: Outright admits most of his reason for becoming a Zodiarts and was simply because he enjoyed it.
 * Frame-Up:
 * From Nobody to Nightmare: Found his switch by complete accident (rather than being selected by the Horoscopes) and still manages to be
 * Meaningful Name:
 * Pegasus: Self explanatory.
 * Pungeon Master: A member of the school's Rakugo Club, he often mixes puns and wordplay into his speech.
 * Especially obvious
 * Red Herring: Was thought to be Haruka.
 * Shadow Archetype: He's pretty much Ryusei without something to keep him good - both put up a Nice Guy facade to hide their more serious personae.
 * The Sociopath: What he's like Beneath the Mask.
 * Wicked Cultured
 * Wings Do Nothing: So far just there for decoration.
 * Wings Do Nothing: So far just there for decoration.

Norio Eguchi/Cygnus Zodiarts
"Live Actor: Shugo Nagashima Voice Actor: Taiki Matsuno"

A student who wishes to be a hero after observing Fourze. He becomes a Zodiarts who styles itself as a Hero of Justice, complete with flashy entrance and catchphrase. However, it possesses a fragile ego and spitefully assaults anyone who slights it. Its patron constellation is Cygnus the Swan.


 * Bitch in Sheep's Clothing: At first it seems like a hero for justice...until JK reveals that Cygnus beats people up who make fun of it.
 * 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.
 * Cosplay: Has an outfit inspired by Cygnus,.
 * Dirty Coward: Used Tomoko as a shield to keep Meteor from bashing him in. He does it again in Episode 24, this time with.
 * 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
 * Fan Boy: Wanted to become a hero after observing Fourze fighting off Lynx Zodiarts in Episode 18 then switched to Cygnus after he was saved from thugs.
 * 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.
 * Paint It Black: His Perpetual Molt does this
 * 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.

Yayoi Tokuda/Coma Zodiarts
"Live Actress: Kasumi Suzuki"

A third-year who is head of the Newspaper Club. She becomes a Zodiarts who uses its hair to create copies of the Chameleon, Altar and Dragon Zodiarts in order to frame their original Switchers and prevent them from graduating. Its patron constellation is Coma Berenices, the hair of Queen Berenice II of Egypt.


 * Bitch in Sheep's Clothing: Seems to be a reasonable Hot Scoop...then she intentionally frames Tamae, Kimio and Ritsuko of wrongs they never commited - all because she doesn't want to graduate and neither will she let the others do so.
 * Camera Fiend
 * Club President: Of the Newspaper Club.
 * The Faceless
 * 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
 * Girlish Pigtails: To a frightening degree.
 * 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.
 * Informed Ability: JK claims that she makes for a better Knowledge Broker than him.
 * Mook Maker: Can turn its hair into copies of existing Zodiarts.
 * Not So Different: 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, Yayoi remains a stubborn Adult Child who refuses to accept it.
 * Prehensile Hair
 * 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
"Live Actor: Jigen Araki"

A freshman who was given his Switch by Libra in an attempt to be more outgoing. His patron constellation is Musca, the Fly.


 * Berserk Button: Due to the Switch, he lashes out at Ran on her insistence on always trying to protect him.
 * Big Creepy-Crawlies
 * Childhood Friends: With Ran. Deconstructed, however, because Ran insists that he should only be friends with her even though Haru wanted to try and befriend Gentaro.
 * 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.
 * I Just Want to Be Badass
 * In a Single Bound: His initial power.
 * 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.
 * : Once he reach Last One.
 * Shrinking Violet
 * Took a Level In Badass: Is noteworthy in that his Switch is evolving even before Last One.
 * Unfortunate Names: Kusao may have been derived from 'kuso', a word with disgusting connotations, as if hammering home his loser image...or Foreshadowing the whole housefly thing.
