Kamen Rider Amazons is a 2016-2018 web series part of the Kamen Rider franchise loosely based on Kamen Rider Amazon. It was specifically planned for release on the Amazon Prime streaming service debuting on April 2016 in Japan and on April 2018 worldwide with English subtitles under the Market-Based Title Amazon Riders (the first official Kamen Rider import since The First). As such, unlike the Merchandise-Driven shows airing in the Sunday morning kids' slot, Amazons is a Darker and Edgier (and Bloodier and Gorier) take on the tokusatsu formula—even more so than the original Amazon series. A re-edit of the first season aired on Japanese television in 2016. A second season was produced following the success of the first, and began streaming on April 2017 in Japan.

The series revolves around genetically-engineered mutants known as Amazonz, around four thousand of which are set loose into an unnamed city after a mysterious lab accident. Though normally able to mimic humans and live peaceful lives, the Amazons regress into ravenous flesh-eating monsters when the medicinal suppressant within their armlets runs out after two to three years.

The story of Season 1 follows a heavily-sheltered Amazon named Haruka Mizusawa, who transforms into Kamen Rider Amazon Omega; the mysterious Amazon hunter Jin Takayama, who transforms into Kamen Rider Amazon Alpha; and the Nozama Pest Control Service, a small group of mercenaries contracted to hunt down the awakening Amazons.

Season 2 reveals that in the five years since the conclusion of S1, the existence of the Amazons has become public knowledge, putting Nozama Pharmaceutical out of business. In their place is 4C (Competitive Creatures Control Center), a new government organisation tasked with hunting down and containing the Amazons threat. However, the Amazon Cells have mutated into a strain capable of infecting humans, transforming victims into insane and bloodthirsty monsters.

Chihiro (Kamen Rider Amazon Neo) is a mysterious young Amazon who struggles to retain his humanity against his primal hunger for human flesh. While on one of his daily hunts for rogue Amazons, he happens to meet Iyu, a young girl who has been resurrected from the dead by 4C as a "Sigma-Type Amazon", an undead, emotionless fighting machine. Chihiro falls in Love at First Sight, and believes that if he can help Iyu regain her humanity, then there is hope for him doing the same.

The series concluded with Kamen Rider Amazons: The Last Judgement, a theatrical movie released in May 2018, with two compilation movies of the first two seasons being released a few weeks before it.

Recurring Kamen Rider tropes include:

  • Defeat Equals Explosion: Subverted. As in the original Amazon as well as the first 13 episodes of original Kamen Rider, monsters don't explode when killed; instead they melt into black goo after being mortally wounded. In season 2, a killed Lysogenic Amazon has their corpse decay instantly.
  • Early-Bird Cameo: Amazon Neo makes his on-screen debut in Chou Superhero Taisen, which came out about two weeks before Amazons Season 2.
  • Finishing Move: Averted with most of the Amazons, whose powers and behavior are purely biological and thus don't have any formal finishers (although ripping out body parts is a common tactic). Played Straight with the two Riders (as with the franchise tradition), as the belt used by Alpha and Omega lets them use certain "Violent" attacks.
    • Violent Punish/Slash: A slash with the sharp protrusions on the forearm.
    • Violent Strike: A kick, with similar protrusions on the back of the leg.
    • Violent Break: Finishing off the enemy with a weapon made from the Driver's Battler Grip (right-hand handle), such as a throwing spear or a kama.
  • Henshin Hero: While the closest this series has to an actual hero is Haruka, much like the original Amazon, the Amazon Riders in this series are more biological than technological. There's no traditional "enemy/hero gets hit, sparks fly", but more "enemy/hero gets hit, they bleed". Their Amazon forms are a biological creature that can bleed and their main source of power is protein. However, with enough force, they will revert to their human forms if they take too much damage. Actually killing them will cause their body to melt.
  • Idiosyncratic Episode Naming: The starting letter of each episode goes in an alphabetical sequence - the first three are titled Amazonz, Beast Inside, and Colony of Ants. Since the first season ends at 13 eps, this carries into season 2. The last episode however, AmazonZ, is the Odd One Out as its meant to be a Book Ends of sorts.
  • Super Mode: Ironically, the Riders' base form is this in a sense: the belts give them greatly enhanced versions of their natural Amazon forms, as shown with Haruka's beltless form compared to his form with the belt.
    • Subverted with the second Butterfly Amazonz as it has a larva/pupa/adult stage like the Dobsonfly Beastman.

This series contains the following tropes:

    open/close all folders 

  • Absurdly Sharp Blade: The Amazon Riders' blades are sharp enough to bisect an opponent with a Finishing Move.
  • Adaptational Wimp: Not the Riders or the Amazonz, but their armlets. In the original Amazon series, Amazon's Gigi Armlet was both the source of his power and a powerful ancient artifact that, when combined with the other armlet, would give its owner incredible, potentially world-conquering power. In this series, their only "power" is to keep Amazons from going berserk by injecting them with drugs that suppress their Amazon Cells, with the belts taking their place as the series' Transformation Trinket.
  • Alien Blood: All Amazons, except Haruka and Jin, have black-ish green blood. Even in human form.
  • Alternate Continuity: To the entire Kamen Rider franchise, according to Word of God. Though they do make appearances in the Chou Super Hero Taisen crossover film.
  • And the Adventure Continues: Season 1 ends with the NPS continuing to be on active duty, minus Mamoru, in hunting down violent Amazons that have survived Operation Tlaloc.
  • And Show It to You: Mamoru kills the first Spider Amazon this way. Alpha also finishes his first fight by ripping out the monster's heart and crushing it while it's still beating.
  • Anti-Hero: Just about everybody in-show, especially Jin.
  • Badass Family: Chihiro's family are major badasses with Chihiro himself being Kamen Rider Amazon Neo and having an Amazon Origin form that is ridiculously powerful, his father Jin, Kamen Rider Amazon Alpha and his mom Nanaha, the Jellyfish Amazon that worfs Haruka.
  • The Bad Guy Wins: The CEO of Nozama Pharmacy is heavily implied to have been the one that released the 4,000 Amazons into the city for the sole reason of making his own warped ecosystemic food chain. With Haruka, Jin, and the Tlaloc survivors still out there, he's gotten the ecological playground he was looking for. By season 2, even with all 4,000 original Amazons dead, there's the new-breed Amazons still out there; and Jin and Haruka are still alive, meaning ultimately he ends the series pretty much getting exactly what he wanted.
  • Big Bad Ensemble: The scattered Amazons are the main threat and largely operate on their own, though some of the more powerful Amazons (like the Bat or Ant Queen) are able to command weaker members of their kind. On the other side, the Nozama Pharmacy (specifically their chairman, Takaaki Tenjo) are responsible for creating them in the first place and are willing to let people die brutal, gory deaths and keep the four thousand maneating monsters roaming the countryside secret just to keep the Amazon Cells to themselves. To top it all off, Tenjo released the Amazons in the first place to cause this whole mess. Season 2 is a bit more complicated as Mamoru and his group started the new outbreak, Jin is constantly hunting down Chihiro with intent to kill him, and Nanaha (now an Amazon) is rampaging about and becomes Jin's Final Boss. Though Tenjo could still be considered the overall Big Bad, seeing as every single thing that happens in both seasons was because of him releasing the Amazons in the first place.
  • Biopunk
  • Bittersweet Ending: Season 1. Operation Tlaloc is a success and kills over three-quarters of the remaining Amazons, the vast majority of whom had yet to do anything wrong. Haruka and Mamoru survive, but have decided that they cannot live within human society and leave with the surviving Amazons. Jin survives and is driven mad by his lonesome crusade against the survivors, but is possibly saved by the intervention of Nanaha.
  • Bloodier and Gorier:
    • Moreso than its Showa predecessor and comparable to Shin Kamen Rider: Prologue. While it lacks High-Pressure Blood, imperfect Amazon Omega is seen biting an enemy, drawing blood and ripping off an arm of a mook; while Amazon Alpha finishes his first fight by ripping the monster's heart out and crushing it. In contrast to Shin Kamen Rider, Imperfect Omega kills his first enemy with the goriest Rider Kick ever, people are Eaten Alive, and Omega cuts the Dragonfly Amazon in half. Later, we have Sigma impaling Omega with his hand complete with blood all over Sigma's hand when he pulled it from Omega's body. The original would be so proud.
    • Season 2 is even gorier than the first, thanks to the increased numbers of Amazon and the people hunting them. And while season 1 mostly confined graphic violence to the Amazons themselves, season 2 has plenty of humans get gorily slaughtered onscreen.
  • Book Ends: "Amazonz" is the title for both the first episode of season 1 and the last episode of season 2.
  • Break the Cutie: Haruka and Mamoru both. See Trauma Conga Line below.
  • Byronic Hero: Jin shows shades of this. Mainly his refusal to work with the company that's trying to clean up the Amazons mess as well as his unrepentant killings of even the most benign Amazon. This puts him and Haruka at odds for the rest of the show. Post-Tlaloc, he's all but devolved into an Amazon-hunting wild animal.
  • Cacophony Cover Up: The Pest Exterminators blast classical music to the whole neighborhood in order to cover up the sounds of a battle inside the house.
  • Came Back Wrong: Jun Maehara's dead body is implanted with Neo Amazon Cells, which reanimates him...minus all emotion and the ability to feel pain. Same for Iyu in Season 2.
  • Casting Gag: It's just a little funny that Jun Yamasaki, typecast by now thanks to Toru Hojo and the Centipede Orphenoch, appears here as the Tragic Monster.
  • Comic Book Movies Dont Use Code Names: Zig-Zagged. The term "Kamen Rider" is never used in show, as is common in a number of the Heisei-era series. Additionally, while their belts do say "Alpha" and "Omega", Jin and Haruka are never referred to as Amazon Alpha or Amazon Omega in dialogue. On the subject of the belts, they're never called the "Amazons Drivers" either. On the other hand, Maehara is referred to as Amazon Sigma by Jin, and Chihiro and Iyu are called Neo and Sigma by 4C in season 2.
  • Corrupt Corporate Executive: Reika seems to be the sole member of the Nozama Pharmacy's higher ups who actually gives a damn about human life. The rest are more concerned about money and the one that actually suggests breaking the masquerade only suggests it to save them money rather than save lives because a seven man team is apparently too expensive of a price to pay for stopping a 4,000 strong army of maneating monsters. Their leader is more concerned about keeping the Amazon Cells property of their company than actually cleaning up their mess.
  • Cruel and Unusual Death: Oh, yes...full stop. One victim is discovered in pieces; another literally gets Eaten Alive in front of his comrades. The monsters get them too, with two getting their hearts torn out, one getting it's head crushed, and one being bisected at the waist. Anyone who saw the original series should've expected this.
  • Darker and Edgier: As a whole, Amazons is definitely the darkest Kamen Rider series Toei Company has made, surpassing the likes of Black, Shin, Ryuki, 555, Wizard and even Urobuchi's Gaim to the point it has almost no verbal humor. Ever. Even more so than the original namesake which, despite the gory finishers, still had the general tone of either a 1970s Showa-era Kamen Rider show or an early 2000s, more-intense Heisei Kamen Rider show. Season 2 is even worse, with a bleaker, more dreary and tragic tone. Yes, Tragedy is part of Season 2's themes.
  • Death of Personality: In Season Two, the new Amazon Cells that transform humans into Amazons are stated to kill the humans' personality as they transform them into Amazons. This is shown when Iyu's father was transformed into an Amazon and then killed and ate his family.
  • Decomposite Character: Amazon Alpha's suit is based on the S.I.C. Hero Saga-only form of Amazon called Pre-Amazon, which is Amazon without the Gigi Armlet.
  • Deconstruction: Amazons deconstruct some of the elements found in Amazon and other Rider series, such as:
    • The Masquerade: Shido points out that there are hundreds of monsters roaming loose, and people are basically just snacks for them. He also doesn't buy that there's a benevolent reason for it, pointing out that the only reason the Nozama Pharmacy would send in a group of Hired Guns to kill the Amazons is because they're hiding something rather suspicious (he's right).
    • Haruka is a deconstruction of a typical Heisei Kamen Rider protagonist in general. He has a flexible sense of morality that gives him a more complete and nuanced understanding of a situation, but makes him inconsistent and untrustworthy to fight alongside. Jin works on a rigid and well-defined ruleset, but this makes him uncompromising at best and dangerously single-minded at worst. The Nozama Peston Service stray more towards the latter out of necessity to do their jobs well, but make a very notable exception in their treatment of Mamoru.
  • Diagonal Cut: The Amazon Riders do this for finishers with their forearm blades.
  • Doing In the Wizard: The original Amazon hand-waved a lot of stuff due to demons and Mayan SUPER SCIENCE. Amazons, on the other hand, is due to a lab accident and a company trying to cover it up.
  • Double Standard: Jin battles against the potentially mass-murderous threat of the Amazons, but is shown in Episode 8 to be just fine with not just protecting, but outright ignoring humans that kill, too.
  • Downer Ending: Season 2 ends with the deaths of Chihiro, Iyu, Nanaha, and Mamoru. Jin is forced to kill both his lover Nanaha and eventually his only son. The Peston crew is forced to kill Mamoru, (who tries protecting the Jellyfish Amazon) only to discover that he still had his ¥5 coin and Chihiro fails to prevent Iyu's armlet from killing her before his own death. Jin and Haruka are the only two named Amazons to survive the season and are once again Walking the Earth.
  • Dramatic Hour Long: A first in a Kamen Rider series outside movies. Justified, due to the web-series format of the Amazon service.
  • Dramatic Irony: The mercenaries figure out that Jin can track their movements, and find a way to send him off to some empty location while they deal with the actual Amazons. The irony comes from how they never set a trap or do much of anything after getting Jin where they want him, while they're the ones who walk right into a trap after the Queen Ant Amazon turned the whole apartment block into her hive.
  • Enemy Mine: In episode 11, Jin ends up helping Haruka and the extermination team to fight against Amazon Sigma. Shido even gives him a hamburger to fuel himself up.
    Shido: Sorry, it's not an egg.
    Jin: [contemplating the change in meal] ...well, beggars can't be choosers...
  • Escaped from the Lab: The origin of the Amazons: they escaped from a Nozama lab. The President of Nozama all but admits to deliberately freeing them two years ago, predicting that a new food chain would emerge.
  • Evil-Detecting Dog: One squad uses a dog named Baron to detect Amazons.
  • Foil: Both Amazon Riders are this to each other. Jin/Alpha is a tough and confident adult, while Haruka/Omega is a frail and sensitive teenager. Jin's apartment is very messy, while Haruka's "house" is neat and solitary. This is inverted when the two are in battle, however; Jin is collected and in-control, while Haruka acts closer to a wild animal. Then dramatically reversed by the end of the first series: Jin has become a bloodthirsty monster no better than a feral Amazon, and Haruka is the in-control one fighting for a civilized reason.
  • Genetic Engineering Is the New Nuke: The creation of the Amazons in general, but becomes explicit when Tachibana moves to manufacture Amazons as obedient weapons. He succeeds by creating the Neo Amazon Cells and Amazon Sigma, but gets shut down after the President of Nozama discovers that Neo Amazons do not need to eat to survive, which disgusts his Evilutionary Biologist side.
  • Grey-and-Gray Morality: The show's morality isn't as simple as "Good vs. Evil". Killing off Amazons would usually be considered heroic, since they're man-eating monsters that pose a threat to humanity...but most of them just want to live their lives and have to go everyday of their lives in fear of becoming monsters and getting hunted down. There will be people who have to end lives because it's necessary, but it's not easy, even for them. Tragic Villains aren't always going to be good people who have to act as villains, but have become so broken that they've become horrible people acting as villains for heroic causes. Even by the end of Season 2, no matter which side you're rooting for, they've lost so much that you're bound to find that neither has really won in the end. The one exception is Takaaki Tenjo, who is genuinely black in terms of morality, but even then other than invoking The Masquerade and kickstarting the whole mess in the first place, he has little direct control of the situation and is never actually fought by either side.
  • Half-Human Hybrid: Amazon Alpha is the result of a human willingly implanting Amazon Cells into himself. Haruka was born by crossing Amazon cells with Reika's own. Chihiro, on the other hand, is Jin and Nanaha's son, making him a natural-born Amazon hybrid.
  • Happy Ending Override: In the second season, we find out that Nozama Pharmacy was hit by such a huge number of lawsuits and fines as a result of the events from Season 1 that the entire company collapsed and went under.
  • Healing Factor: Amazons can rapidly recover lost stamina and even heal life-threatening wounds by consuming proteins, be they from hamburgers...or humans.
  • He Who Fights Monsters: After the Time Skip, Jin's bloody crusade against the surviving Amazons and his feasting upon their corpses has transformed him into a monster.
  • Hourglass Plot: As seen in Foil above. Particularly delineated in Jin's and Haruka's fighting styles, wherein the former starts out as a cocky and confident fighter and the latter as a feral warrior, and by season two Jin is blinded and fights more haphazardly whereas Haruka fights with a calm confidence.
  • Hulking Out:
    • Transforming into an Amazon seems to be this, at least for the ones that can control it. Mamoru and Haruka are much more animalistic and berserk in their transformed state, though they're at least in control enough to tell friend from foe.
    • Subverted with Amazon Alpha, who is completely in control of his transformed state and thus far the only Amazon to be so.


  • "I Know You're in There Somewhere" Fight: Subverted in "BEAST INSIDE". Maehara thinks that he can reason with Otaki, who has transformed into the Dragonfly Amazon. It...doesn't end well.
    • Receives an Ironic Echo when the mercenaries find themselves fighting Maehara as Amazon Sigma.
  • In Name Only: Despite supposedly being a re-imagining of Kamen Rider Amazon, it really has nothing in common with it apart from the suit designs and violent fight scenes.
  • I'm a Humanitarian: Amazons, as shown with what happened with the victims in the inn. The Exterminators even called them leftovers.
    • Jin is revealed to have become an "Amazonarian" post-Time Skip.
  • In a Single Bound: Both of the Amazon Riders have shown some impressive jumping abilities. Shown most clearly in episode 2, where Omega travels from a city to a quarry in record time mainly by leaping around.
  • Invocation: All the Riders use "Amazon" in place of the franchise standard "Henshin".
  • Ironic Echo: At the end of the Shrike Amazon arc, Shido tells Haruka that mercenaries' morals and decisions can only be decided by who's paying them. Later on, the team nearly leaves Haruka on his own in the city to face certain death, until Mamoru convinces all of them to stick together by offering up his coin collection, which counts as payment.
  • Ironic Nickname: Amazon Alpha and Amazon Omega are called the Wild Type and the Cultivation Type respectively. However, Haruka is more feral in his Amazon form than Jin, who likewise is calm and collected. It's more accurate for their human identities- Jin has more of a survivalist mindset while Haruka is repeatedly compared to a pet.
  • "It" Is Dehumanizing: In Way to Nowhere the remaining personnel of 4C start referring to Chihiro as "the point of origin", because of his status as the source of the Amazonz outbreak, following his rampage and escape from HQ.
  • Leaning on the Fourth Wall: When he leaves when Tachibana contacts him, he forgets to kiss Nanaha good-bye before leaving, wondering if it's forshadowing something. He gets his answer encountering a newly revived Jun Maehara, who ends his Invincible Hero status.
  • Manchild: Mamoru. One episode even shows him having to be comforted with toys to receive some shots. He also takes longer than the others to recognize that Amazon Sigma is not quite Jun Maehara anymore. Downplayed example since he's biologically 16 (and would be much younger than the rest of the extermination team either way), but he is still very childlike for that age.
  • Masquerade: The Nozama Pharmacy is covering up the existence of the Amazons, hence why the group are called the Pest Exterminators and carry that facade. Shido is actually not happy with this, and points out that Nozama is hiding something if they don't just call the police and military in. Episode 3 reveals that the real reason for the cover up is Nozama's boss wants to keep the Amazon Cells the sole property of their company.
    • In Season 2, Tokyo has become more aware of the outbreak and thus, the Competitive Creatures Control Center is formed to combat them and keep things from reaching the public.
  • Medium Awareness: This line from Jin, while he and Haruka are in their Amazon forms:
    Jin: You don't have to be so pissed off. Not that I can see, I mean.
  • Monster of the Week: Deconstructed by the Amazons. See What Measure Is a Non-Human? below.
  • Mythology Gag: Has its own page.
  • No Hugging, No Kissing: Averted. Jin is very affectionate with his girlfriend/partner Nanaha, regularly kissing her on the mouth.
  • Obstructive Bureaucrat: Reika wants to expand Shido's group and give them better tech to stand a better chance of killing the Amazons...but the rest of the Board of Directors and her boss are Corrupt Corporate Executives more concerned about keeping the Amazon Cells to themselves and making things "cost-effective" than actually dealing with the 4,000 man-eating abominations that escaped from their labs.
  • Operation: [Blank]: Operation Tlaloc. Named after the god of rain. The goal for this mission: eliminate all Amazons in the Greater Tokyo Area through an anti-Amazon mist rain.
  • Painful Transformation: Anyone who undergoes an Amazon transformation, but Haruka is a prime example while transforming into Amazon Omega. Subverted with Amazon Alpha, who doesn't seem to experience any pain from transforming.
  • Painting the Medium: The On the Next segment previewing "Under Wraps" starts with "Next Hunt" like the first-season previews instead of "Next Target" like the other second-season previews, because it mostly takes place between the two seasons. Similarly, that episode itself starts with "Armour Zone", the first-season main theme.
  • Police Are Useless: Justified: the Nozama Pharmacy is covering up the Amazons' existence, so the police are unaware they even exist. On the other hand, the Public Security Bureau is helping Nozama by covering any unusual disappearances (usually attributed to the Amazons) as missing person's cases.
  • Practically Different Generations: In Season 1, Mizuki is 17 and Haruka biologically 20; but he's an Amazon created two years ago, so Mizuki is chronologically 15 years older than he. They become this trope with the revelation that they're genetic half-siblings, due to Mizuki's mother incorporating her DNA into Haruka.
  • Protagonist Journey to Villain: The entirety of Season 1 is this for Jin and Mamoru, but Haruka was a subversion. Jin is obvious and Mamoru turns his back on humanity by leading the remaining benign Amazons in order to exact their revenge against humanity.
  • Red Eyes, Take Warning:
    • Armlets showing red eyes are a warning that the Armlet has run out of drugs to suppress the Amazons Cells, which leads to the person turning into an Amazons shortly after.
    • Haruka's first transformation into Amazon Omega has his human eyes turn red.
    • Chihiro from season two eye's glow a piercing red-orange color as he transforms. As as well as having red eyes under an orange visor in his Amazon form.
  • Red Herring: Due to Jin's disappearance in Season 2, it was hinted that he was killed and his corpse was the source of the lysogenic cells. Schooldays reveals that the cells are similar to Chihiro's cells and that Jin is still alive.
  • Red Shirt: Nozama has other crews besides the Pest Controllers for other purposes, but they're more or less this when they show up. Out of the team appearing in episode 4, only one actually makes it out alive.
  • Sdrawkcab Name: Nozama Pharmacy, anyone?
  • Sensitive Guy and Manly Man: Haruka and Jin, respectively.
  • Sequel Hook: The last moments of season two are Tachibana declaring a new Sigma project as there are still Amazons alive.
  • Spell My Name With An S: The title, and the name of the monsters, is either spelled Amazons or Amazonz.
  • Spiritual Antithesis: Srprisingly one to Kamen Rider Amazon.
  • Spiritual Successor: Arguably one to Shin Kamen Rider: Prologue.
  • Surprisingly Realistic Outcome: Haruka's unwillingness to do more than protect Amazons is certainly noble, but doesn't get anything done and only puts those he cares about in more danger from threats he won't deal with (IE: Jin). By the time of Season 2, Mamoru is fed up with Haruka's hesitation and has turned on Humanity wholesale.
  • Stuffed In A Fridge:
    • The Queen Ant Amazon puts her victims' remains in one this way.
    • The Crab Amazon also does this to serve human meat to unawakened Amazons.
  • Time Skip: Season 2 takes place five years after "M".
  • Tragedy: Surprisingly, Amazons makes Urobuchi's Gaim look like the works of saints, to the point that the Central Theme of Season 2 IS Tragedy.
  • Tragic Monster: In the spirit of the Showa series, this was bound to come up. Eps. 7-8 have the Shrike Amazon, who's barely clinging to sanity from fighting the need to feed for a long time, even getting the idea to hang around a Serial Killer to feed on the bodies he leaves behind. It doesn't quite work out, and he's put down for his troubles.
    • In Episode 9, the owner of the restaurant that serves Amazon customers. While the murders of passersby and confused wanderers is undeniably wrong, he's allowing his clientele to eat Human meat to delay their Awakenings and maintain something resembling normal lives. He even tries to valiantly defend his customers from the Pest Exterminators. He fails.
  • Transformation Trinket: The Amazons Driver belts for Amazon Alpha and Omega. When Nozama gets ahold of Jin's, they replicate it to create one for Amazon Sigma.
  • Trauma Conga Line: Yes. Haruka decides not to take his medicine and becomes Amazon Omega, then he's taken in by the Amazon-hating Jin, whose "advice" worsens Haruka's existential crisis, THEN he begins meeting Amazons that retain their sanity, his sympathy in turn alienates him from just about everyone that gives a damn about him, and then most of that nice Amazon population is wiped out in Operation Tlaloc, and then his other Amazon ally gives into instinct and munches on a team-mate's arm, and then in the Last Episode, Jin makes it his life's mission to eradicate the Tlaloc survivors and keeps attacking Haruka's troupe of survivors, which has forced them to all but retreat from Humanity as a whole. And then Jin attacks them again, opposed by the Nozama mercenaries this time though.
    • Mamoru, to a lesser extent. After having ate human meat unknowingly in Episode 9, he nearly loses his mind to his instincts two episodes later, knows he may be labelled as a target by the people he's called friends for ages, and is forced to retreat from humanity alongside Haruka; reluctantly choosing to deny the Exterminators' attempts to re-recruit him onto the team.
  • Upgrade vs. Prototype Fight: The battles between Haruka and Chihiro during the first half of Season 2 are this, but Haruka's greater combat experience helps him win tidily against the less seasoned Chihiro's more advanced belt, tougher armor, and large array of higher quality weapons. An exaggerated version occurs whenever Jin and Chihiro fight due to Jin being Chihiro's father.
  • Van Helsing Hate Crimes: Jin wants to kill every Amazon, even the ones that have yet to attack humans and just want to live peacefully, and even a baby who happens to be his newborn son. Also himself, but he pretty much needs to take care of all the others first.
  • The Virus: Downplayed in Season 2: there are a new type of Amazon Cells that infect humans and turn them into Amazon, but it isn't passed by air or touch. The cells have to be ingested in order to take root—and even then, only people with certain DNA will change.
  • Wham Episode:
    • In episode 8 of season 2, we find out that the Amazon killed in the first episode was Chihiro's mother Nanaha.
    • In episode 9 of season 2, Chihiro transforms into his true form and rampages, killing a good number of 4C including Kano, and incapacitating Tachibana. Before expiring, Kano reveals that there is another source of the Isyogenic cells.
  • Wham Line: Near the end of Season 2's Episode 7:
    Jin: I've been looking for you. You're Chihiro, aren't you?
    Chihiro: Dad!?
  • Wham Shot: Season 2, Episode 9. A rare look inside the nursing home where Fukuda's mother lives...and the Aroma Ozone water cooler in it.
  • What Measure Is a Non-Human?: It might as well be the central theme of this series in both seasons:
    • Season 1 involved Haruka, who had this trouble when he found out he is an Amazon by Jin, who actively hunts them down. When he realizes the true nature of the Amazons, he wants to protect humans and Amazons who had not awaken. The source of his conflict is when he sees unawakened Amazons who just want to live normal lives, but he puts his foot down when they are being targeted. As he is aware that those who have awakened, he intends to end their lives as so they don't harm any other humans. In the last episode of the first season, he and Mamoru, who at that point is horrified that he ate Misaki's arm, go to live with other Amazons in self-imposed isolation from humanity.
    • Season 2 involved Chihiro, a boy who was once human that became an Amazon. He willingly disregards being called am Amazon and calls himself a human, despite his I Am a Humanitarian issues. When he meets Iyu, he discovers not only is she a fourth type Amazon, but most of her humanity is gone due to her resurrection. He goes as far as to protect her, even if she can't feel anything, emotional or physical, despite receiving minor memories.
    • Iyu is a human resurrected as an Amazon Sigma. Before her death, she had a loving family and friends. However once incident changed everything when her father was infected by Chihiro's blood. It eventually lead to the deaths of her mother, sister, and herself, who was the last one to die. After her resurrection, she was made as a fighting machine to eliminate other Amazons, and Chihiro tried his hardest to help her remember being human. Despite these attempts, she can only recall memories of her past life. But as of episode 11, she finally regained her sense of self after saving Chihiro from Jin.
    • In general, the Amazons aren't just your typical Tokusatsu Monster of the Week the heroes defeat on a weekly basis. They are Artificial Humans that simply wanted to live a normal lives. The problem is that most them tried their damnedest to prevent their Horror Hunger from happening. But once they have a taste of human flesh, there's no going back to whatever "normalcy" they had. The remaining original Amazons in Mamoru and Haruka's group realizes they don't want to eat anyone, no matter what their nature is. One of the straighter examples is an Amazon named Shuuya who is in love with a human woman named Emily. After 4C mistake her for an Amazon, Shuuya murders those involved. When he sees her again, he Mercy Kills her, and tries to fight off the Amazon Riders and Iyu, only to die by their blades.
  • Whole Episode Flashback: Season 2 episode 8 takes on the unenviable task of summarizing the Time Skip between seasons.
  • Xtreme Kool Letterz: Thanks to the alphabetical Idiosyncratic Episode Naming, the third-last episode is called "Xing The Rubicon" (as in "crossing the Rubicon").
  • Younger Than They Look: The Amazons we see in Season 1 all have different biological ages, from 16 (Mamoru) to middle-aged (some of the Amazons of the week) but are chronologically only two years old. Chihiro is born during the five-year Time Skip between Season 1 and 2, but is already in his late teens due to accelerated aging.
