History Characters / KamenRiderZeroOneHidenIntelligence

* TenderTears: Is shows herself to somehow be capable of crying, which she develops from the simulations of Aruto dying multiple times. This should be physically impossible for a [=HumaGear=] as she should not have tear ducts or even biological eyes capable of creating moisture and even she seems baffled how she's doing it. Once Is is restored within her second body that one shows itself to be capable of producing tears as well.

* OddFriendship: Forms one with Poppy in Girls Remix with them getting paired off and becoming particularly close despite Poppy being an overly hyper GenkiGirl (although her "serious" Poppy personality briefly shows at one point) while Is despite having developed emotions at this point is still rather polite and reserved to everyone. They share a common bond of being non-human technological based beings that became self aware Is being a RobotGirl that and Poppy being a digital game character and even combine their talents to have Is transmit Poppy into Black Satan's security system to get Poppy inside to open the gates for the team.

* ReplacementGoldfish: The Is we see in the finale of the show is this to the original Is, as they share a physical appearance but no memories. Aruto takes it upon himself to re-teach her everything that her predecessor knew. Subverted in ''[=REALxTIME=]'' when Is the Zero-Two Progrisekey and the original Is's backup is restored onto the new Is.
* RippleEffectProofMemory: In ''Kamen Ride Reiwa: The Next Generation'', she was already aware of the changes to the timeline when Aruto finds her again, and it's heavily implied at the end that she remembers the altered timeline that was otherwise erased with Finis' death.

** Just before [[spoiler:Zea gets destroyed and its satellite taken over by Ark-Zero, it manages to escape by transferring the core of its programming [[FusionDance into Is.]]]]

* NoPlansNoPrototypeNoBackup: Because of the data she has about the Zero-One Project, there are no backups of Is's central memory, unlike many other [=HumaGears=]--and there ''never'' will be, even with her [=HumaGear=] Progrisekey, in order to avoid a potential security leak. If she's ever irreversibly hacked or completely destroyed, [[DeaderThanDead there's no bringing her back.]] [his is proven when it's shown that the new Is introduced in the finale does not have her personality from before her death, reverting all of her character development. It's later heavily implied that this was {{Subverted}} almost entirely ''by accident'': REAL×TIME shows that Zea did have a backup of the original Is' data, implicitly because the Zero-Two Progrisekey was created from Is' central memory, allowing the original Is to be restored.

** Both [[Series/KamenRiderExAid Poppy Pipapopo]] and Is are the main chicks of the series. Poppy was a GenkiGirl Bugster, supporting the main protagonists in CR; while Is was an EmotionlessGirl until she reached Singularity. Both became Kamen Riders, although Poppy's was her own while Is had to borrow the Zero-Two Driver in order to be one.

* RobotGirl: She's a [=HumaGear=] modeled to have a female appearance.

* LegacyCharacter: Downplayed at first, then zig-zagged; She temporarily becomes the second Kamen Rider Zero-Two to fight alongside Aruto, who decided to use Realizing Hopper instead, to defeat Behru and end Thinknet's destruction, but Is hasn't completely given up the role though and borrows the Driver from time to time as seen in Girls Remix.

[[folder:Other Personnel]]

* LoopholeAbuse: How Zea allows Aruto to continue being Kamen Rider Zero-One. As stated in Korenosuke's will, only the President can be allowed to use the Zero-One Driver. [[spoiler:However, Zea and all technology relating to the Zero-One Driver and [=HumaGear=] were patented under the Hiden family name, meaning Aruto owns the tech, not Gai.]] Also, Korenosuke [[ExactWords never specified the user had to be the President of ''Hiden Intelligence''.]] [[spoiler:Is takes full advantage by having Zea register all of Aruto's patents under his new company, HIDEN Manufacturing.]]

* MoralityPet: [[spoiler:To Gai.]]

* TookALevelInBadass: In the ''[=REAL×TIME=]'' film, Is goes from being a non-combatant that acts as support for Aruto to fighting side-by-side with him, even becoming [[UpToEleven Kamen Rider Zero-Two]].

* ContrastingSequelMainCharacter: Both Is and [[Series/KamenRiderZiO Tsukuyomi]] are close friends to their series' main protagonists, but their paths diverge in a few ways. Is automatically became Aruto's assistant after he was appointed as a CEO of Hiden, while Tsukuyomi chose to befriend Sougo in order to prevent him from becoming Ohma Zi-O. Is is a [=HumaGear=] created by Hiden Intelligence, giving her a lot of knowledge but no real emotions, while Tsukuyomi is a resistance fighter and originally a princess willing to destroy time, until she lost her memories with a full range of emotional expression. They also both died near the end of their respective series, were revived in the finale epilogue with no memories of past events, and transformed into Kamen Riders at some point, but at different times and in different ways: Is became the already existing Kamen Rider Zero-Two by borrowing the Driver from Aruto in the post-series movie ''[=REAL×TIME=]'', while Tsukuyomi became the original rider Kamen Rider Tsukuyomi in the last episodes of her series.

* StockCostumeTraits: He's a detective, therefore he dresses in the stereotypical SherlockHomage deerstalker getup.

* HollywoodDressCode: He's a detective, therefore he dresses in the stereotypical SherlockHomage deerstalker getup.

* YouGottaHaveBlueHair: She has green streaks in her hair.

* AwesomenessByAnalysis: [[spoiler:Integrating Zea's data]] gives Is the ability to experience simulations so advanced that they border on clairvoyant and are nigh-indistinguishable from reality. [[BlessedWithSuck This is]] '''[[BlessedWithSuck not]]''' [[BlessedWithSuck as great as it might first sound.]]

** In #42, [she falls for As's claims that Horobi will become the next Ark and will kill Aruto, and believes she can prevent this by [[BreakThemByTalking talking him out of it]] while keeping Aruto LockedOutOfTheLoop for his safety. This ends up eliciting [[DontYouDarePityMe the same reaction]] from Horobi as with Jin earlier and [[PoorCommunicationKills results in her getting killed by his hands]] this time.

* ExactWords: In his will, he states that only the company president may be allowed to use the Zero-One Driver. [[spoiler:He never said it had to be the President of ''Hiden Intelligence.'' Is takes full advantage of this loophole since Korenosuke patented all technology relating to Zero-One and [=HumaGear=] under the Hiden family name and has Zea register them under Aruto's new company, HIDEN Manufacturing. In turn, Aruto is allowed to continue using the Zero-One Driver as the President of his own company.]]

* DistaffCounterpart: To Aruto's version of Zero-Two, as her Rider physic is more feminine compare to Aruto's version.
