History Characters / ShinKamenRider2023

* TheUnfought: [[spoiler:Never even comes face-to-face with Hongo, being killed by government forces. {{Justified}}, as Ruriko mentions that Sasori's venom is lethal to Augments, and the Anti-SHOCKER Alliance agreed that they couldn't risk Hongo and Ruriko dying to it while there are still other Augments to deal with.]]

* FragileSpeedster: The sole Augment in the film that displays outright SuperSpeed, [[spoiler:but a single shoulder toss is enough to leave Hachi Aug totally vulnerable to a [[FinishingMove Rider Kick]], only surviving her encounter with Kamen Rider because of Hongo's choice to deliberately miss the attack. This is simply relative to the other Augments though, as Hachi Aug boasts to Tachibana and Taki that she's ImmuneToBullets when the latter draws his gun.]]

* AnimalThemedSuperBeing: Like the Double Riders, they're based on grasshoppers, but more specifically their behaviour as locusts, acting less like individuals and more of a collective swarm, eerily mirroring each other's movements as if connected by a HiveMind.

* {{Expy}}: Of Goro Maki of ''Film/ShinGodzilla''. Both are posthumous characters who have already set the events of their respective films into motion, leaving others to deal with the consequences.
* MotherlyScientist: Gender-Inverted: Daizo treats his AIs with reverence, speaking to them as people and letting them know he has great hopes for them. Before shooting himself, he seems to pass the metaphorical torch to K, by giving him his SHOCKER ring.

* {{Foil}}: To Kamen Rider. Whereas Takeshi is able to change between his Augment form and human forms, Kumo Aug's transformation is permanent, reflecting their relation to their humanity. [[spoiler: Kumo even chides Hongo for reverting to his human appearance, a process that leaves him relatively weaker than his Augment form.]]

* FullyEmbracedFiend: Downplayed as he overall was pacified afterwards, but Kumo after becoming fully Augmented in SHOCKER SIDE, embraces a dog-eat-dog world, saying that human morals are superficial over-complications, preferring a predator's lifestyle. He genuinely believes this mindset makes beasts "beautiful."

* MadScientist: A more straightforward example compared to Professor Midorikawa. Koumori Aug's idea of "happiness" involves spreading a "perfect virus" of his own design that would allow him to mind control (and kill, at any moment of his choosing) anyone infected by it.

* EvilCounterpart: While attention isn't explicitly drawn to it in the film, K.K Aug's design features some commonalities with the Batta Augs/Kamen Rider and [[spoiler:the SHOCKER Riders]]. Specifically, K.K possesses a simplified Typhoon belt with a black turbine; [[spoiler:the SHOCKER Riders also have Simplified Typhoon belts]]. His face and left arm are both revealed in his fight against [[spoiler:Hayato Ichimonji]], in an inverse of Takeshi Hongo's discovery of his own mutant body in the first arc. K.K's fight against [[spoiler:Ichimonji]] even echoes Hongo's against Kumo Aug, except with K.K swinging wildly whilst his opponent dodges his attacks.

* SinisterScythe: Possesses an organic mantis scythe [[BladeBelowTheShoulder on his left arm]].

* KiManipulation: His direct application of Prana in this manner (which manifests as bright blue energy) illustrates the sheer power disparity between himself and every other Augment in the film, who simply employ it to enhance their physical attributes. Even more impressively, he demonstrates this ability before entering his Augment form. Ultimately {{Deconstructed}} though, as this proves to be more AwesomeButImpractical than anything, especially with his throne destroyed.

* NotSoStoic: The previously cold and detached Ichiro appears to be on the verge of tears when he [[EvenEvilHasLovedOnes senses Ruriko's death and quietly grieves.]] During the CombatBreakdown of his fight against the Double Riders, Ichiro expresses his irritation at their persistence and goes into an impassioned MotiveRant when grappling with Hongo. Finally, when meeting Ruriko's VirtualGhost within Hongo's helmet, he hugs his sister, then backs away with tears in his eyes after telling her that he cannot join her without sacrificing either her or [[WorthyOpponent Hongo's]] soul in the process.

* DecompositeCharacter: The Great Leader of Shocker role has been split across several charcters. I is not the founder, but the closest thing to the overall leader and supporter of the organization's schemes.

* MeaningfulName: Twofold. It's an AI, and its name is pronounced as ''ai'', which his homophonous with the kanji for love, 愛. It's also a homophone with "eye", indicating its role as an observer.

* WithGreatPowerComesGreatResponsibility: In a twisted way, Hongo (at least, according to [[HazyFeelTurn Professor Midorikawa]]) wanted to obtain power that would allow him to prevent what happened with [[spoiler:his father's death]]. But the power Hongo was "given" simply crosses the line from "superior" to "horrific". [[{{Deconstruction}} He can't really control his strength, and it is mostly based on violent self-preservation.]] As such, he literally has received more power than he desired, with all the negatives that entails. Because of this, it is an almost [[{{AnAesop}} aesop-worthy]] exploration of asking for such physical strength without considering the consequences. Nevertheless, Hongo uses his power to battle SHOCKER's members and protect mankind from the organization's clutches.

An ally of Hongo's following his augmentation. Having recently abandoned SHOCKER along with Dr. Hiroshi Midorikawa, she intends to stop SHOCKER and their activities, and has freed Hongo from SHOCKER's lab to that end.

* AdaptationalBadass: In the original show, Ruriko was an ordinary university student whose father was wrapped up in Shocker's heinous activities. Here, Ruriko is a defecting member of SHOCKER who seeks to stop them, obtaining a firearm from the Intelligence Official to protect herself. However, one of her greatest assets against SHOCKER is [[spoiler:her nature as a "computational organism", allowing her to create and modify SHOCKER software via prana as needed]].

* CrazyPrepared: Ruriko often boasts of her thorough preparations in her {{Catchphrase}}, and lives up to it throughout the movie.

** [[spoiler:Her gambit to bring Ichiro's [[OurSoulsAreDifferent prana sequence]] into Hongo's mask fails because there's only room for two prana sequences in the hardware, and Hongo's body [[HeroicRROD is about to dissolve]]. Ichiro realizes that this, so he decides to give up his place in the mask so that Ruriko and Hongo can still live on, a choice that leaves both Midorikawa siblings on the verge of tears.]]

SHOCKER's chief biochemistry specialist, and an Augment whose modifications are based on the bat.

* {{Flight}}: His wings allow him to fly up to heights that not even [[InASingleBound Kamen Rider]] can reach. [[spoiler: Unfortunately for Koumori, he didn't count on the Cyclone's NitroBoost.]]

* NonStandardCharacterDesign: Unlike his fellow Augments and the Double Riders, Koumori doesn't sport a CoolHelmet or stylized costume, opting for a rather mundane lab coat and suit ensemble, including a hat with two openings in the brim to make room for his large ears. The lack of "armored" components in his costume design, as well as his more obvious mutation, incidentally makes his physical appearance more reminiscent of his original [[MonsterOfTheWeek kaijin]] counterpart from the TV show.

* AnimalThemedSuperBeing: [[BeeAfraid Bees]]/[[WickedWasps Wasps]][[note]]"Hachi" (ハチ) can refer to either group of insects interchangeably.[[/note]]. The English subtitling specifically refers to Hachi Aug as "Wasp-Aug", and her PreAssKickingOneLiner has her describe herself as a ''suzumebachi'' (スズメバチ), which means "wasp".[[spoiler:That said, the track that plays during Hachi Aug's death scene is titled "kill the bee" in the official soundtrack]].

* {{Catchphrase}}: "Ara ara"/"Oh dear".

* DualBoss: In the first phase of her second encounter with Hongo, she fights him alongside her top lieutenant, before eventually draining said lieutenant so she can transform.

* {{Foil}}: To Ruriko Midorikawa. Both were born in SHOCKER and were the closest thing either had for a friend in the Organization, but their paths diverged: Ruriko abandoned SHOCKER in order to stop them, whilst Hiromi embraced the Organization that would give her what she wanted. Their roles in combat sharply contrast: while Ruriko only uses actual weapons once, preferring to use her abilities as a computational organism; Hachi Aug is a DarkActionGirl. Both even treat their male partner-in-crime differently: while Ruriko relies upon Takeshi's abilities as Kamen Rider from beginning to end, Hachi Aug uses her manservant's prana and discards his body, for a battle that she loses.

* HenshinHero: A villainous example that stands out among the Augments by maintaining her human appearance for the majority of her screen time, much like the Double Riders and [[spoiler:[[BigBad Ichiro Midorikawa]]]]. When in need of a power boost, [[DevourTheDragon she drains the Prana from her subordinates to trigger her transformation.]] She also uses a transformation phrase: the English word "Change".

* {{Yandere}}: Has some shades of this in her personality. She expresses her desire to make her old friend-turned-CategoryTraitor [[EmotionlessGirl Ruriko]] cry.
* WickedCultured: Certainly cultivates this image, holding a meeting with Ruriko and Hongo in a classy lounge at the top of her brutalist concrete tower lair. She offhandedly apologizing for running out of Goût de Diamants, a ''prohibitively'' expensive champagne that generally costs more than $1 million per bottle; and instead offers the relatively-cheaper Shipwreck champagne, the average cost of which is $14,181.81 per bottle.

* EvilCounterpart: While attention isn't explicitly drawn to it in the film, K.K Aug's design features some commonalities with the Batta Augs/Kamen Rider and [[spoiler:the SHOCKER Riders]]. Specifically, K.K possesses a simplified Typhoon belt with a black turbine; [[spoiler:the SHOCKER Riders also have Simplified Typhoon belts]]. His face and left arm are both revealed in his fight against [[spoiler:Hayato Ichimonji]], in an inverse of Takeshi Hongo's discovery of his own mutant body in the first arc.

SHOCKER's MasterComputer and the central foundation of the organization as a whole.

* MeaningfulName: Twofold. It's an AI, and its name is pronounced as ''ai''. It's also a homophone with "eye", indicating its role as an observer.

* CharClone: He's an EnigmaticMinion within the ranks of SHOCKER and the brother of the female lead. Ichiro also has a [[HiddenAgendaVillain personal agenda]] through his plan to save all of humanity by transferring their souls (including those from SHOCKER, as revenge for his father and Ruriko's death) to the Habitat Realm, which mirrors [[Anime/MobileSuitGundamCharsCounterattack Char's intention of migrating humanity into space through crashing the Axis asteroid on Earth]]. The prequel manga also shows that he previously wore a [[GoldColoredSuperiority gold-colored]] prototype combat suit, a possible nod to Char's [[Anime/MobileSuitZetaGundam Hyaku-Shiki]].
