Haruka Mizusawa/Kamen Rider Amazon (New) Omega

Portrayed by: Tom Fujita, Yugo Fujii (Suit actor)

Kamen Rider Amazon New Omega

• Artificial Human: The third type Amazon.
• Anti-Hero: A rather downplayed example starting from Season 2. While he still retain some of his heroic traits, Haruka goes into great lengths to stop Chihiro from meeting up with an already unstable Jin. It doesn't work.
• The Berserker: Tends to let his Amazon side take the reins when he's in battle. It shows. It's also his fighting style in contrast to Jin's martial arts style and Chihiro's self taught brawler style.
• Berserk Button: Do not: Harm his family, friends, allies, and innocents whether they're human or Amazon. Results will get messy.
• Beware the Nice Ones: Haruka's a nice, gentle person. But of the three Amazon Riders, he's absolutely brutal and vicious in combat.
• Big Brother Instinct: He acts like a surrogate big brother to Mamoru even though Haruka couldn't be any older than him. In the final episode of S1, he convinces Mamoru to join him in abandoning human civilization and contact to live peacefully, and even saves him when he's badly injured in S2, despite now being enemies. He also shows this to Mizuki after becoming an Amazon, such as rushing to her aid when an Amazon is after her. In fact, she's probably one of the person Haruka cares about the most. Even after he decided to turn his back on humanity, Haruka still cares for her. When they finally meet again in season 2, even when Mizuki tries to kill him, Haruka doesn't hold it against her and still treats her kindly.
• Big Eater: He has to. Episode 11 actually shows him scarfing down his meal after he completely healed.
• Blood Knight: Every time Haruka joins a fight, his inner Amazon becomes engrossed in it. He ends up having an epic but disturbing Slasher Smile as a result.
• Break the Cutie: Happens to him after slaughtering an enemy. It only gets worse from then on.
• Broken Pedestal: To Mamoru, who looks down on him for being satisfied with just protecting Amazons.
• But Now I Must Go: He, alongside Mamoru and other Amazons, went on to go live in peace outside human contact. Unfortunately, it was rather short lived.
• Byronic Hero: Jin sees Haruka as this; seeing his moral compass as flexible based on who he likes and doesn't. This cultivates in him having to restrain Haruka when the latter attempts to murder the serial killer in Episode 8. This extends into Season 2, his Heroic Neutral stance toward Humans and Amazons preventing him from making any kind of real difference; ultimately turning Mamoru against Humanity.
• Cain and Abel: What befell the relationship between him and Mizuki. Haruka still cares for her, though and as Rambling Roses shows, he still watches over her from the shadows when he can.
• Cannibalism: Is forced to eat a dying Muku (Though she spurred him to do so) near the end of Last Judgement to survive the mortal wounds inflicted on him by Neo Alpha and Jin. He attempts to drown himself in a lake out of penance, but an illusion of Mizuki talks him out of it.
• Character Development: In Season 1 he was meek and unsure, after the Time Skip he's become far more confident and stoic.
• Cool Bike: The Junglaider, a much more sleeker version of the Jungler. It even adjusts to Haruka's Amazons Cells to make him able to ride it easier, as Haruka doesn't know how to ride a motorcycle normally.
• Confusion Fu: Which is combined with his berserker-type fighting tendencies.
• "Could Have Avoided This!" Plot: By Episode 12 of second season, he painfully aware that he is mostly responsible for the event of season 2 as he was the one who helped Nanaha and Chihiro escape Jin.
• Curbstomp Battle: In his first fight, he bites the Bat Amazon, tore its wings off, and literally stepped its face in with a very gory Rider Kick.
• Deconstructed Character Archetype: Of your usual Kamen Rider protagonist. Most mainline Rider protagonists, including the original Amazon have a very clear view of good and evil. Others develop complexity but still retain their views on good and evil. Haruka has a very complicated and gray motives when it comes to being a human and Amazon. Haruka will protect Humans despite their implicity in hunting Amazons but will also protect Amazons...until they eat someone. In any other Kamen Rider season, a neutral stance would be lauded as the best of both worlds. In Amazons, those mixed sympathies get Haruka written off as a Wild Card unable to invoke any real change, which causes rifts between him and those he loves.
• Diving Save: He saves Mizuki this way in Yellow Brick Road just before some of Chihiro's tentacles kill her.
• Doomed Moral Victor: Though the misfortunes pile up, Haruka nevertheless insists on trying to find a way for both humans and Amazons to live together in harmony, a scenario where neither side has to hunt the other into extinction. However, extremists of both species capsize whatever solutions he attempts to implement.
• Dynamic Entry: He makes his first appearance in his complete form by slamming into an Amazon from a very long jump.
• Failure Hero: From Season 2 onward, all Haruka can really do is watch things fall apart. His fellow Amazons call him out for his hesitancy to terminate Jin getting them killed, (Which isn't wrong) his attempts to Mercy Kill Iyu are constantly interrupted by Chihiro, keeping Jin away from Chihiro fails and even his New Omega upgrade is functionally useless in half the battles it engages in. The only thing he manages to accomplish is help Jin kill Chihiro off-screen.

• Good Is Not Soft: By the time he meets and faces Chihiro, most of his fights were one-sided and non-lethal (at least the way he does non-lethal). This is because he knows who his parents are.
• Genetic Engineering Is the New Nuke: He is the result of his mother's and Amazon cells.
• Gilded Cage: Haruka originally lived in one, which he akins to an aquarium.
• Half the Man He Used to Be: What some of his Finishing Moves do to their target.
• Healing Factor: Haruka has a much better one than any other Amazon, enough so that he's even capable of surviving having a hole punched through his chest. It's best showcased in his fight with Jin between seasons, which ended in both combatants inflicting deep injuries on the other, but Haruka recovers with no lasting damage while Jin doesn't regain his sight until much later.
• The Hero: Haruka is technically the titular main character of the entire series as he is easily the most heroic among the Amazon Riders. While Chihiro is the viewpoint main character in the 1st half of season 2, Haruka still holds this position from time to time.
• Hero Antagonist: When he finally appears in ORPHANS, he transforms after seeing Iyu and intends to Mercy Kill her until he clashes blades with Chihiro. RAMBLING ROSES reveals that he's still protecting Mamoru's group of innocent Amazons as well.
• Heroic Neutral: Played for Drama. Haruka has a distinct inability to apply himself to a cause. He's too wishy-washy to truly fight alongside Humans yet he's too soft to deal with threats (chiefly Jin) to the Amazons he's protecting. While he's fine with culling aberrant Amazons, he's too detached to truly make a dent in the Vicious Cycle between the races; prioritizing Mercy Killing Iyu and keeping Alpha away from Neo instead. This results in others viewing him as a bystander unwilling to get anything done, which eventually prompts Mamoru's Face–Heel Turn.
• Hulking Out: While both him and Mamoru do this, it's much more pronounced with him, as he goes from a gentle person to The Berserker in a constant state of Unstoppable Rage.
• Hunter of His Own Kind: Like Jin. The only difference is that Jin wants all Amazons dead. Haruka wants unawakened ones to stay alive, but will kill any one of them that is on the verge of eating a human. It's this reluctance to unambiguously hunt all Amazons that puts him and Jin (and later on him and Captain Shido) at odds during Operation Tlaloc.
  • During Season 2, hunting Iyu is his only real goal, though he'll also kill Amazons that have eaten people.
• In a Single Bound: As Amazon Omega, he reaches the site of the battle in "BEAST INSIDE" this way, jumping across entire city blocks at once.
• Irony: Haruka turns his back on humanity, but the humans of the Nozama Pest Control are the only people who have never tried to use him or stabbed him in the back, a fact he acknowledges when he goes to them for help in season 2. Even if Fukada decides to stay with 4C he tells it too him to his face and stabs him in the front.
  • Haruka's insistence on staying his hand from both sides ends up a factor for the races fighting in the next season.
• It's All My Fault: He blames himself for the new Amazons being born as he was away when the rest of his group put the plan into motion.
• Mercy Kill: What he will do to Amazons that awaken.
  • He fully intends to do this to Iyu since he was friends with her and her family. When he discovered her father killed everyone save Kurosaki, he didn't hesitate until he sees Iyu pleading until she passed on.
• Mid-Season Upgrade: Gets a new Amazon Driver similar to Chihiro's around the halfway point of Season 2, becoming Amazon New Omega. However, he lost access to the form when Neo Alpha destroyed it in The Last Judgement.
• Only Friend: At the start of the series, he was only close to Mizuki due to his confinement. This changes once he escapes.
• Only Sane Man: Out of the Riders in Season 2, Haruka is the most well put together.
• Our Hero Is Dead: Was seemingly killed by Amazon Sigma during Episode 10 of the first season. However, he gets better in the next episode after he was sent to the Nozama Pharmacy by feeding him some meat to revitalize his condition.
• Protagonist Journey to Villain: Played With. He went from The Hero to Hero Antagonist over the course of the Time Skip. But Rambling Roses shows he hasn't changed in the least, just now he doesn't have a direct connection to humanity. Turns out that he's too busy trying to stop Jin from going after Chihiro, hence why he blinded Jin in their recent fight.
• Red Eyes, Take Warning: "AMAZONS" first shows this when he changes to Omega.
• Sensitive Guy and Manly Man: The Sensitive Guy to Jin's Manly Man. During Season 2, he inherits the "Manly" spot while the young Chihiro ends up the new "Sensitive", and when Jin returns, he's the "in-between" towards Jin's "Manly Man" and Chihiro's "Sensitive Guy".
• Shoot the Dog: Him killing Chihiro at the end of season 2, knowing that Chihiro is too dangerous to live. He's pretty disgusted with himself afterward, wanting Mizuki to kill him.
  • In The Last Judgement, he's forced to eat Muku to survive (though she goads him to). He's Driven to Suicide afterward, though an illusion of Mizuki stops him.
• Sixth Ranger: Becomes part of NPS to help them hunt down awakened Amazons.
• Slasher Smile: A rare heroic Kamen Rider example. He puts one on in episode 6. In episode 13, he's practically grinning as he faces off a burned Jin.
• Superpowered Evil Side: Initially his Origin form acts like a violent berserker on its first appearance, but Haruka takes control of himself unless he's very angry. Even at his Rage Breaking Point in control of himself.
• Super Prototype: A biological version. He's revealed to be a third type Amazon.
• Swiss-Army Weapon: The battler grip of the Amazon Driver can be pulled out for it to turn into various different weapons, like a spear, a whip or a pickaxe.
• Sword over Head: Even on one occasion between the seasons where Haruka had Jin at his mercy, he couldn't bring himself to kill Jin.
• Teeth-Clenched Teamwork: While he's fine working with the Extermination team, it's Jin he worries about, though they'll have to fight together against dangerous Amazons. It culminates him teaming up with Jin to kill Chihiro in Season 2's finale.
• Tomato in the Mirror: Didn't know he was an Amazon until he became Omega for the first time.
• Took a Level in Badass: His fighting style becomes much more refined and strategic by the end of the first season.
  • He takes another in Season 2, his posture is no longer animalistic, being composed like Jin's was, and despite Chihiro having a superior belt he can still casually manhandle him, even when Chihiro goes full Determinator. He's pretty much inherited Jin's Showy Invincible Hero status of early season 1.
    • Although in the season 2 finale, he briefly reverts back to his feral fighting style when Chihiro was about to slash through Mizuki.
• Trademark Favorite Food: While he'll eat anything with high protein, he appears to eat hamburgers more, as he shows Mizuki a cheeseburger stashed in his jacket.
• Trauma Conga Line: By the end of the first season, this Cutie isn't just broken, he's been warped beyond anything resembling what he started as.
• Unstoppable Rage: Pretty much his default state when he's Amazon Omega. Justified, as he implies Omega is a representation of his repressed anger and rage at being stuck in a Gilded Cage his entire life.
• What Measure Is a Non-Human?: He has this problem in episodes 2 and 3. After being told that he is an Amazon by Jin, he questions whether or not if he would ever consider himself a human being. It took Nanaha and his mother to tell him to decide if he considers his inner Amazon a human. Jin however doesn't care, since he considers Haruka being alive to be an important factor rather than questioning his existence as a human or Amazon.
  • He actually has a very personal view of this. When he met a restaurant full of unawakened Amazons, they wanted to live normal lives and hold off their awakened selves. Of course Shido gives him a massive What the Hell, Hero? look at him when he lets them go. But No Good Deed Goes Unpunished as they die anyway when his mother deploys Tlaloc on them, killing them all. However, he does not count awakened Amazons, since they'll feed on humans.
• What the Hell, Hero?: Jin calls him out after holding an Amazon dead-to-rights, hesitating after he pleads, and allowing him to escape, knowing full-well that women are being murdered. He also calls him out later for wanting to murder the very-Human serial killer that tortured Takai and Mamoru.
  • Come Season 2, he's on the receiving end of this from everyone. Humans still view him as a Wild Card while Amazons see him as a Failure Hero that won't actually solve problems.
• Wide-Eyed Idealist: Played for Drama. Haruka is just about the only character who believes peace between humans and Amazons is an achievable ideal in the face of both sides continuing to kill one another. This is however not portrayed as a positive. Haruka's idealism is generally derided in-universe as blind during the first season and outright detrimental in the second; ranging from inconsistency to outright Bystander Syndrome. His Heroic Neutral mentality is consistently demonstrated to be noble yet ineffective, putting more people in danger than it saves. By the end of both seasons, only one person still (barely) trusts him and he's enacted no lasting change.
• Why Don't You Just Shoot Him?: Haruka's restraint against Jin between the first and second seasons alienates him from the Amazons at-large, Mamoru seeing him as a Failure Hero that's only getting them killed.
• Wild Card: In season 2, no one is sure of his goals and what he has been during between the Time Skip. The answer is stopping Jin and Chihiro from seeing each other and letting Iyu rest in peace.
• Worf Effect: After spending Season 2 as a Showy Invincible Hero and even changing into New Omega, Haruka is manhandled to show how dangerous Nanaha is as the Jellyfish Amazon.
  • Continues in The Last Judgement. He can barely hold his own against the two Amazons that attempt to attack the farm early on in the film and is utterly routed by Neo Alpha to demonstrate what a threat he is..
• Younger Than They Look: Looks like a full grown human, but is only two years old. Lampshaded when he realizes he doesn't have any memories from before then.

Tropes Exclusive to him as Amazon Omega / New Omega

• The Berserker: Omega's Origin form is little more than a wild beast. Downplayed with his standard form, which only fights like one but is in full control.
• Bio-Augmentation: New Omega sports a visual like this, looking like an incomplete cyborg.
• Blade Below the Shoulder: New Omega has a retractable wrist-blade not unlike Neo's.
• Cool Sword: The New Omega Sword.
• In a Single Bound: Amazon Omega is capable of crossing city-blocks with just a jump.
• Finishing Move:
  • Violent/Amazon Punish: A powerful swipe from his arm-blade that can outright bisect an enemy with enough force.
  • Violent Break: Uses the Battler Grip for three distinct weapon-finishers:
    • Spear: Omega impales the opponent(s) with a thrown spear.
    • Whip: Omega grabs the opponent with a whip and pulls them in for an arm-slice.
    • Scythe: Finishes an opponent with a downward slash.
  • Violent Strike: Omega's Rider Kick. A leaping kick that sees Omega jump over the opponent and slice them with blades on his calves.
• Javelin Thrower: One of Omega's Battler Grip weapons — a javelin that can impale multiple opponents at once.
• Mid-Season Upgrade: Omega receives a Neo Amazons Driver during Season 2, allowing him to transform into New Omega.
• Sinister Scythe: One of the three weapons of the Battler Grip.
• Strong Flesh, Weak Steel: Non video game example. The psuedo-mechanical New Omega is ragdolled by nearly every opponent it tackles, almost all of whom are organic monsters.
• Superpowered Evil Side: Very loose definition of "evil," granted. Omega's Origin form is an Ax-Crazy berserker, but is quickly tamed into the significantly-more-stable Amazon Omega when filtered through the Amazons Driver.
• Super Prototype: A biological version, being a new Amazon species dubbed the Cultivation Type.
• Swiss-Army Weapon: The battler grip of the Amazon Driver can be pulled out for it to turn into various different weapons, like a spear, a whip or a pickaxe.
• Unstoppable Rage: Pretty much Amazon Omega's default state. Justified, as Omega represents Haruka's repressed anger and rage at being stuck in a Gilded Cage his entire life. Downplayed come Season 2, where aside from one battle he's a considerably more tactical fighter ala Alpha.
• The Worf Effect: New Omega is subjected to it repeatedly near the end of Season 2 (as well as The Movie), making Omega's weaker forms look stronger by comparison.

Jin Takayama/Kamen Rider Amazon Alpha

Portrayed by: Masashi Taniguchi, Hirokazu Iwakami (Suit actor)

Jin (above), Kamen Rider Amazon Alpha (below)

• Aloof Ally: Whenever he shows up in a fight with the Monster of the Week. Especially around Haruka.
• Anti-Hero: Regardless of his resolve to protect humanity, even if they're good or bad, he only fight for his own agendas whatsoever.
• Archnemesis Dad: While their exact relationship is unknown, Chihiro went to great lengths to hide that Jin is his father and his reaction to seeing him again is far from pleased.
• The Atoner: He blames himself for the original Amazon outbreak, so much so that he turned himself into an Amazon and completed development of two belts to hunt them down.
• Badass Biker: He has a normal motorcycle. Doesn't hurt his badass look.
• Bait-and-Switch: Viewers are led to believe Jin lost an arm and regrew it during the Time Skip and it matches Chihiro's blood. He didn't. The arm belonged to Nanaha, who was killed by 4C.
• Barefisted Monk: While Haruka occasionally uses his belt's weapons, Jin prefers to fight barehanded with only his ridged gauntlets for added offense.
• Big Eater: Deconstructed. He needs to eat meals with high protein, hence his chicken coop in his apartment.
• Boomerang Bigot: He wants every single Amazon dead, including himself.
• Brought Down to Badass: Subverted from season 2 onward. His blindness has made him a weaker, more wild fighter. Despite this handicap, he is still an unchecked threat to nearly everyone he encounters and can slaughter most Amazons with ease. Against Omega and Neo however, he doesn't stack up anymore. ^note Omega knows enough of Jin's style to be able to counter it; being the one that blinded him. Neo and Alpha are evenly-matched on their own....until Origin comes out.
• Byronic Hero: He can be an ass, but he does have benign reasons for killing the Monster of the Week. While he begrudgingly fights with Haruka and the extermination team, he does it only for his and Nanaha's sakes.
  • Episode 8 reveals he intends to protect humanity. Regardless if you're a mass murderer or not.
  • Continues in Season 2. An anti-Amazon serial killer that refuses to listen to any kind of reason other than his own, making enemies of just about everyone he knows for what he thinks is a good cause.
• Curbstomp Battle: His first fight with the second Spider Amazon. It's quick and brutal, with him manhandling it before ripping its heart out.
• Covered with Scars: All those green marks you see on him as Alpha? All of them are scars from past battles that unlike Haruka's do not seemed to have healed.
• Create Your Own Hero: Took Haruka back to his home in Episode 2 in hopes of gaining a powerful accomplice and wound up with an insufferable rival instead.
• Cruel Mercy: How Jin sees that fact that he's still alive at the end of Season 2.
• Death Seeker: The Last Judgement reveals he desires death after everything he's been through and the knowledge that he'll just create more Amazons.
• Deconstruction: Of the Reluctant Mad Scientist archetype of the Kamen Rider franchise who goes rogue in an attempt to atone for the mayhem his experiments have caused. Jin shows that guilt of such magnitude married with the kind of mentality that would have allowed him to create creatures like the Amazons in the first place might not result in the most heroic (or even stable) character.
• Defector from Decadence: It's revealed that he willingly put the Amazon cells in himself to destroy the experiments.
• Determinator: He simply will not give up. In his second fight with Amazon Sigma, Sigma asks him at one point how he's still standing, to which Jin replies that it's because he doesn't want to fall over. In the final episode, he says that he'll keep coming after Haruka and the Tlaloc survivors until they're all dead. Even being blinded during the time skip between seasons barely slows him down.
  • In Season 2, he'll not stop at killing Chihiro, even after being blinded by Haruka in their recent fight.
• Detrimental Determination: His determination to kill all Amazons takes a dangerous toll on his sanity throughout the series.
• Dramatic Irony: In season 2, his on-going crusade damages his relationship with Nanaha, the latter running away from him due to his one-track mindset of eliminating every Amazon he finds, him acting more monstrous than the Amazons he's created. It heavily affects his close relationships with just about everyone. This includes Nanaha, who was pregnant with Chihiro. Haruka attempts to reason with him, but he refuses, causing Omega to blind him in the ensuing fight; forcing him into a four-year wandering of the world trying to find them. The self-destruction leads to Nanaha's death and Chihiro being taken by the humans who experimented on him, thus leading to the events of the second season.
• Establishing Character Moment: The first thing he does before he fights is crack open an egg with his belt and eats it raw. Then transforms in front of those involved.
• Eye Scream: His recent fight with Haruka (as Amazon Omega) ends badly for him when the latter cleaves off his eyes to stop his attempted killing of Chihiro.
• Facial Horror: Episode 13 shows that at least the left side of his face and neck have become hideously scarred. It's unclear if this is because of his Amazon cells degenerating him, accumulated scars from his cannibalistic "hunts", or if they're chemical burns from Operation Tlaloc. By the time season 2 rolls around, the scars have completely healed.
• Fate Worse than Death: How Jin sees being alive at the end of Season 2. Considering he just murdered his family to keep humanity alive and has no one left, he's depressingly correct.
• Finishing Move: Violent Slash, similar to Haruka's Violent Punish.
• Foil: While they are both Kamen Riders they are the exact opposite in personality and color. This is even represented in their suits, they both have a red and green motif but while Jin's is majority red with green stripes, Haruka is majority green with red stripes. In terms of personality while Jin will kill all Amazons and save every human, Haruka believes in a saving those that are innocent, meaning he'll happily kill murderers but protect unawakened Amazons like Mamoru. Jin is a human who injected himself with Amazon cells, while Haruka is an Amazon altered to possess human DNA.
• Genocide from the Inside: Outright admits that this is his goal. Given the rest of his species are a race of man-eating monsters that, once they lose control are impossible to reason with or talk down, this is more understandable and less evil than most examples.
  • Episode 6 reveals why: He was against the idea of sending out the Amazons after 2 years.
• Go Out with a Smile: His final moments are him smiling at seeing Nanaha again before his dead body is shown alone, implying it to be either a Dying Dream or being Together in Death with his family.
• Handicapped Badass: Spends season 2 blinded from a fight with Haruka. By the time of Final Chapter, his eyes have recovered.
• Half-Human Hybrid: He's a human who injected Amazon cells into himself. He's categorized as a second type Amazon.
• Healing Factor: He has one, but it's much weaker than Haruka's. Jin typically takes months or years to recover from injuries that take Haruka hours, but he will eventually recover from them.
• He's Back!: Finally make his return in the final scene of season 2's episode 6.
• Hero Antagonist: For a certain definition of "hero" anyway. Initially, Jin was a Boomerang Bigot who saw his crusade against the Amazons as a fight to protect humanity. While brusque and uncompromising, he had a vague semblance of right and wrong. Post-Sanity Slippage, much of that civility is gone and in its place is a madman that tap-dances on top of the line between protector and serial-killer; murdering every Amazon he can find with a sadistic smile on his face. In season 2, he even tries to kill Chihiro, his own son, to stop the spread of the new Amazons.
• Heroic Self-Deprecation: Well some kind of self deprecation, but he agrees with Nagase that he's a piece of shit in Xing the Rubicon as he tries to kill his own son.
• Hidden Depths: For an alcoholic, protein-eating Amazon Rider, he excels in cell biology.
  • He seems to act like a dick to Haruka, but he seems to mean well. Haruka obviously does not reciprocate.^note  Justified, as Jin had stated that he and Mamoru are on his hit-list too; just presumably down at the very bottom. Not a philosophy that makes you friends.
  • He considers killing Amazons as an act of Mercy Killing because he cares.
  • Even after his Sanity Slippage in episode 13, it's implied by his tearful conversation with Nanaha that he wants a normal life.
• Hunter of His Own Kind: Is an Amazon himself despite hunting other Amazons. The finale shows him eating Amazon remains to sustain himself.
• Impaled with Extreme Prejudice: Finally dies in The Last Judgement when Haruka impales him through the stomach with his arm.
• Invincible Hero: Up until his fight with the newly-revived Jun Maehara, Kamen Rider Amazon Sigma.
• It's All My Fault: Xing the Rubicon reveals that Jin doesn't blame Chihiro but instead himself for everything that is happening.
• Jerk with a Heart of Gold: While he can be a dick, he willingly feeds Haruka at every chance he gets. Even saving him from certain death.
• Jerkass Has a Point:
  • The reason why he clashes with Reika is because Reika intends to release the Amazons after two years, but Jin was highly against it. Considering the 4,000 Amazons have awakened and began eating people, he definitely has a point.
  • His point of conflict with Haruka, while Haruka is against murdering Amazons that haven't harmed humans yet or at least want to stay sane as long as possible, he has a point that it's inevitable that all Amazons are going to awaken and Haruka's ideals will just result in a lot of innocent people being eaten.
  • If everyone had chosen to kill Chihiro prior to Season 2 like he wanted them to, none of the season's events would've happened. But, they spare the child. This creates the Aroma Ozone pandemic plaguing Japan in Season 2.
• Kill the Ones You Love:
  • Episode 12 reveals he's doing this to the Amazons. He actually likes them due to the amount of work he invested to make them. But he doesn't believe it's right for humanity to be eaten to ensure their survival therefore the least he can do is kill them himself.
  • Yellow Brick Road has him realizing that Nanaha is not only alive but an Amazon and he resolves to kill her himself. The episode ends with Nanaha finding him as they stare at each other. He does the deed in Amazonz^note The final episode to Mercy Kill her
• The Last Dance: With Tlaloc seemingly poised to wipe out most of the Amazons (including himself), Jin elects to spend his last moments defending the Nozama Pharmacy headquarters from a hoard of newly awakened Amazons.
• Laughing Mad: From Episode 12 onward.
• Luke, I Am Your Father: He's Chihiro's father.
• Made of Iron: The injuries he sustains in season 2 is outright ridiculous. From a point-blank shotgun to the head to being impaled, and he still hasn't kicked the bucket. His determination stops him from doing so.
• Manly Man: He chugs raw eggs from a beer jug, doesn't seem to care about personal looks or hygiene, and even "prepares" food by himself. To make it even better, his transformed self is called Amazon Alpha.
• Mercy Kill: Offers to simply kill Haruka for this reason, because if he does, then Haruka will never transform into an Amazon and eat anyone, dying without blood on his hands. Haruka turns him down, instead joining the fight.
  • His philosophy toward his anti-Amazon crusade in general.
• Mythology Gag: While Alpha and Omega both have similar appearances to him in their incomplete forms, Jin's full suit more closely resembles the original Kamen Rider Amazon.
  • Jin's blindness is reflected in Alpha's eyes, which change from green to white. The original Amazon's eyes changed from red to yellow when he was temporarily blinded in his episode 19 of his series.
• Never My Fault: After encountering Iyu and checking her face, he realizes she's an Amazon Sigma and pins the blame on his son. Yet he was the one who got Iyu's father infected with Chihiro's blood, which caused several incidents happening. Subverted when he admits that he actually blames himself for them rather than Chihiro.
• Offing the Offspring: While he'll protect Chihiro as Nanaha wants him to, he'll willingly kill him if he ever loses his humanity as he tells him when he tells Chihiro he reeks of blood.
• Prophet Eyes: Has these in season 2 due to going blind from his and Haruka's recent fight in the intervening 5 years. This is even reflected in his Amazon form's eyes also going white.
• Protagonist Journey to Villain: Downplayed, given the Gray-and-Gray Morality at-play. Jin starts off as uncompromising but fairly reasonable, with a vague sense of right and wrong and self-awareness in regards to his fight. Near the end of the first season however, he continues to pursue the remaining Amazons despite Operation Tlaloc wiping most of them out. It's at this point that his crusade veers into unhealthy, obsessive territory: The sudden opposition to his crusade from numerous sides as well as Nanaha being pregnant with half-breed Chihiro between seasons is what makes him finally snap; turning him into a major antagonist for Season's 2's endgame.
• Psychopathic Manchild: Two years worth of bloodlust, guilt, and hard living turned him from a respectable scientist to a ditzy vigilante to a deranged psychopath. To emphasize this, Nanaha alternates between being his lover and his nanny for much of their relationship.
• Sanity Slippage: He becomes very unhinged near the end of 12. In 13, he ate an Amazon's heart.
  • Episode 13 also shows that his personality has deteriorated from calm and smug to practically being a wild animal, howling like a beast and going Laughing Mad during combat.
  • By the time Season 2 roll around, Jin's mind is finally reduced to a rabid serial killer that needs to be put down. Haruka is not pleased at the outcome. The major trigger is when Nanaha is pregnant with his child, who would be the first half-breed Amazon. By the time Nanaha gave birth to Chihiro, they left him. Haruka then blinds him, setting him off to Walking the Earth to find them both.
• Science Hero: A rare straightforward occasion where the creator of the Kamen Rider belt is one of its principle protagonists.
• Smug Super: Big time. He casually walks into his first fight, gives a smug smirk, and then after transforming takes a few moments to casually point between the present monsters (you can easily imagine him thinking "Eeny, meeny, miny, moe...") before annihilating Spider Amazon.
• Teeth-Clenched Teamwork: As much as he often teases Haruka, and tend to act like a giant dick to him, he does care about Haruka in his own weird way. They both fight efficiently together as much as they do against each other. With the NPS, as much as they don't like him, they do back him up when he needs help and vice-versa.
• Took a Level in Badass: Subverted. His stats show that his offensive power has modestly increased between the two seasons (Haruka needs to upgrade to New Omega to ultimately exceed him in that department), but he's deteriorated in every other respect both physically and mentally.
  • Played Straight in the final movie: When his eyes have healed, he is able to defeat and kill Neo-Alpha, an opponent that Haruka as New Omega previously struggles to defeat. This is even more notable since he has never received any upgrades.
• Trademark Favorite Food: As with most Amazons, Jin would usually consume protein-rich foods to prolong his transformation and sustain himself, though he's frequently seen eating eggs before heading into fights. He would switch to other Amazons later in Episode 13.
• Trickster Mentor: Seems to act like this to Haruka.
• Unwitting Instigator of Doom: The entirety of season 2 was in fact his fault. Rather than being happy that Nanaha is pregnant, he was utterly shocked when he found out. Those involved which includes Haruka, Nanaha, and Iyu's father chose to help Nanaha escape from him. When he sees Iyu's father, he lashes at him, to the point of being infected by Chihiro's blood. He then faces off against Haruka, who begs him to end his crusade against the Amazons, but the latter is put in a position where he blinds him. Had he listened at all, Nanaha wouldn't be infected, and her parts being used to create more Amazons.
• Used to Be a Sweet Kid: He used to be a Nice Guy, but when his crusade against the Amazons pierces through his sanity, that's all he cares about. Iyu's father was even horrified by what he has become.
• Would Hurt a Child: Hurt? Like he would rather kill a child, just as what he planned to do to his own son.

Tropes exclusive to him as Amazon Alpha

• Bare-Fisted Monk: Only uses his fists in combat, not that he really needs any weapons.
• Boring, but Practical: Amazon Alpha has little in terms of gimmickry, but his raw skill is more than enough to close the gap.
• The Berserker: During Season 2, Alpha's fighting style has devolved into this; emphasizing Confusion Fu to compensate for his lack of sight.
• Brought Down to Badass: Jin may be blind during Season 2, but he's no less of a threat than he ever was.
• Clipped-Wing Angel: Subverted. Amazon Alpha's eyes turn a dull gray to demonstrate Jin's blindness. He isn't any weaker in this form, but he becomes reliant on his other senses to guide him, making him more predictable than before.
• Counter-Attack: Alpha uses this a lot against opponents (especially after losing his eyes), goading them into punishing counters and grapples.
• Confusion Fu
• Finishing Move:
  • Violent Slash: Alpha jumps at an enemy from mid-range and slices them with his arm-blades.
• Eye Scream: Is blinded by Amazon Omega between seasons, as seen by Alpha's eyes losing their color.
• Handicapped Badass: His blindness has not made him any weaker.
• Healing Factor: His body can heal and regenerate like other Amazons, though it's lacking compared to the other Riders. It takes him longer to regain his eyesight than it does for Haruka to heal from a hole in his body.
• Piranha Problem: Despite looking the most like the original Amazon, Jin is the Piranha Amazon.
• Red Is Violent: Subverted. Alpha is calm and collected against his enemies despite his uncompromising, brutal philosophy. Season 2 comes with the loss of his eyesight and the trope playing straight, Alpha's style and mentality becoming more primal. He's the Wild Type for a reason.
• Shout-Out: Alpha's design is a modernized take on the original Kamen Rider Amazon.
• Wrestler in All of Us: Alpha adds more grappling to his repertoire during Season 2, lacking the sight for finesse.

And this kid goes through a lot of shit in the course of Season 2.
• Classical Anti-Hero: Although he's a Nice Guy and a good fighter, Chihiro is plague with his urge to eat humans as his weakness, his desire to be normal, and his guilt over having devoured his mother, directly or indirectly.
• Combat Tentacles: His true Amazon form has a large number of them that are razor sharp.
• Cooldown Hug: He gives one to Iyu as she starts remembering her death.
• Cool Bike: Much like Haruka, Chihiro has his own Junglaider with yellow eyes instead of green.

• Fights Like a Normal: His fighting style is largely self-taught and conservative, lacking the savagery and finesse of his predecessors.

They were both then raised in isolation but while Haruka actually enjoyed it till he finally left, Chihiro escaped. Haruka spends the first season sympathetic to Amazons and wonders if he can be still considered human, Chihiro hates Amazons and refuses to admit that he's an Amazon.
• Foreshadowing: His Amazon form looks like a blue version of Jin's Amazon and he transforms with red energy just like Jin. Haruka tells Mizuki to be weary around Chihiro. Knowing Haruka, he wouldn't warn those closest to be careful without a reason. Because he knows Chihiro is Jin's son.
• Freak Out: Has a huge one in Vanishing Wings when he realizes the destruction he caused.
• Freudian Excuse: His hatred of Amazons comes because he succumbed to his Amazon instincts and took a bite out of his mother. This resulted in his mother's transformation into an Amazon and presumed death.

• Half-Human Hybrid: The Third Degree reveals that he's the son of Jin, also a Half-Human Hybrid, and Nanaha, a human.

• The Hero Dies: He's killed in battle, off-screen, by Jin and Haruka following his rampage. If one ignores his non-canon status among mainline riders, this makes him unique as only the second main Rider to die and not be resurrected during the series after Kamen Rider Ryuki, and the only one to stay dead.
• Horror Hunger: To his displeasure, he wants to eat humans. This was present ever since birth.
• Hunter of His Own Kind: Hates the Amazons and hunts them down despite being raised by Amazons and being an Amazon himself.
• I Am a Monster: As a result of his rampage in Vanishing Wings, Chihiro considers himself a human eating monster.

• I Love You Because I Can't Control You: Why he fell for Iyu. She's the only human that he doesn't want to eat.
• I Reject Your Reality: Chihiro refuses to admit he's an Amazon, to the point where he rejects a register from Tachibana that would stop his cannibalistic urges.
• It's All My Fault: Chihiro believes its all his fault for everything that's happening in season 2 due to being a point of origin.
• Killed Off for Real: Dies fighting Jin and Haruka in an off-screen battle.
• Killed Offscreen: His death isn't shown even though he about to engage in a fight against Jin and Haruka.
• Like Father, Unlike Son: Chihiro is like his father because they want to kill all Amazons. Except that while moody, Chihiro is a nice guy. Jin is a snarky Jerkass who lost his sanity trying to mass-murder every Amazon. Adding to that Jin has thrown away his humanity and is planning to die at the end of it, while Chihiro spent most of season two clinging to his humanity and desperate to live.
• Love at First Sight: Chihiro is immediately attracted to Iyu upon seeing her for the first time.
• Mix-and-Match Critters: His Amazon Origin form blends elements of his parents, the Piranha and Jellyfish Amazonz, along with his own spider elements.
• Multi-Armed and Dangerous: Chihiro's true Amazon form has six arms.
• My God, What Have I Done?: After regaining his senses, he sees the destruction of 4C with horror and runs away before seeing the blood on his hands as he starts to break down.
• Nothing Is Scarier: Amazon Origin, his true Amazon form, is an obscenely powerful berserk monster that walks through anything in its path like a living blender. The viewer also never gets a clear shot of what it looks like outside of promotional materials, leaving many of the horrible details to the imagination while viewing.
• Not So Stoic: While he's generally quiet, push his buttons and he'll start screaming.
• One-Winged Angel: In Vanishing Wings, he transforms into his Amazon form which is a multiple-armed monster with tentacles when about to be forced into stasis. He eventually transforms back into his human form without any memory of his actions, however.
• Patient Zero: Under Wraps reveals he's one of the sources for the Lysogenic cells.
• Rage Breaking Point: Pushing this kid emotionally is generally a bad idea. Doing it will cause Chihiro to lose control and awaken his Origin form, which becomes a mindless berserker that will kill everyone in his path.
• Red Eyes, Take Warning: When he transforms, a device he uses for his Driver turns his eyes orange-red until he becomes an Amazon Rider. He has red Amazon eyes under his orange visor.
• Restraining Bolt: His belt allows him to safely tap into his Amazon powers, but unlike Haruka's or Jin's, his Kamen Rider form is actually much weaker than his Awakened state.
• Sensitive Guy and Manly Man: As series progress and closer introduction in Season 2, the contrast shown that Chihiro is the sensitive to Haruka Manly Man. Emphasized by Chihiro main objectives and interest to get along with his fellow Amazons(in case Iyu) in more friendly manner and having such intimate bonds. Also Chihiro combat style is much reckless and lacking combat experience.
• The Stoic: He doesn't really emote a lot and generally comes off as depressed.
• Spin-Offspring: Turns out he's Jin and Nanaha's son.
• Suicide by Cop: As Iyu dies in his arms and his mother truly dead (though he doesn't know this), he has nothing else to lose and agrees with Haruka and Jin that he is too dangerous to live, but wants to fight for his right to live.
• Superpowered Evil Side: Unlike Haruka, his Origin form is very violent, attacking anyone indiscriminately. Whereas Haruka is in control at even his most violent point, Chihiro does not, and his Origin form only shows up at his most emotional boiling point.
• Supporting Protagonist: While he's the main character of Season 2, Haruka is also involved with his existence due to Jin's He Who Fights Monsters mindset.
• Together in Death: The final shot in the season 2 finale suggests this with both his mother and Iyu.
• Tragic Monster: Due to his unique biology, he's incredibly dangerous to humanity despite not doing anything directly. Despite his attempts to remain human, he realizes that he's too dangerous to live and in the end, he dies fighting Haruka and Jin. For bonus points, he's was at most chronologically four at his time of his death.
• Trauma Conga Line: Way to Nowhere is a very brutal one as he considers himself a monster due to his rampage last episode and spends the episode on the run from his father, 4C and Iyu trying to kill him. While also thinking that his mother even thought to kill him due to Jin. This gets worse as even through, Iyu was showing signs of regaining her sense of self, Tachibana turns on the HP round in her armlet, slowly killing her. In the end, Chihiro gets himself killed by fighting Haruka and Jin, agreeing that he's too dangerous to live.
• Troubling Unchildlike Behavior: Episode 1 of second season reveals he used to BITE the doctors that tried to treat him to the point of bleeding.
• Tyke Bomb: He was raised as an Amazon Rider by 4C.
• Unskilled, but Strong: Very much so. While he lacks finesse and The Berserker-Confusion Fu of the other Riders, in his own way, he is a strong fighter. Against Haruka and Jin, he doesn't stand a chance against either one-on-one in a straight fight.
• Unwitting Instigator of Doom: His own existence is the cause of all of the events of season 2 due to his unique biology that mutates humans in Amazons. Haruka even suggests that his cells turned Nanaha into an Amazon before he was even born.
• Vigilante Man: He works with Team X to protect the city from the recent spate of Amazon attacks, serving as The Big Guy in the team. They don't last two episodes and he moves on to the 4C.
• What Measure Is a Non-Human?: Notice a trend? Unlike Haruka, who questions his own existence whether or not he is a human or an Amazon, and has a personal viewpoint of this to unawakened Amazons that just wanted to live a normal life, Chihiro openly denies that he is an Amazon and considers himself a human. His Hates Being Touched issue is that it makes him want to eat people if they touch him. And then it comes to a head when he meets Iyu, who is an Amazon Sigma, and he has no desire to eat her because she's already dead. Since then, he goes out of his way to protect her if she gets injured too much. And then the negative side rears its ugly head in episode 9 when despite all of his attempts of staying human, he realizes that he was the Amazon that ate and presumably turned his mother into an Amazon. And when he wakes up from a slaughter that he caused, albeit unknowingly, he breaks down that he feels like a monster.
• With Great Power Comes Great Insanity: His Amazon Origin form is one of the most obscenely powerful Amazonz seen in the entire series, capable of tearing through an army of Amazonz Hunters. He's also completely mindless and uncontrollable in that state, unable to tell the difference between "friend" and "foe".
• Younger Than He Looks: He was born sometime during the 5 year time skip between seasons 1 and 2, at most he's four years old and the first episode of season 2 states that his growth was enhanced.
