History Characters / KamenRiderZiOProtagonists

* AmbiguouslyHuman: The reveal of her time powers put into question what she even is when Swartz says they're cut from the same cloth. [[spoiler:#43 reveals that she ''is'' human, but from a different timeline than the rest of the cast.]]
* AmnesiacHero: She has no memories of her past before joining the future's LaResistance, [[spoiler:courtesy of her brother]].

[[folder:Tsukuyomi]]
!!Tsukuyomi[[spoiler:/Alpina/Kamen Rider Tsukuyomi/Alpina Tsukuyomi]]
!!!'''Portrayed by:''' Shieri Ohata (live)[[spoiler:, Natsumi Sano (suit)]]\\

[[spoiler:Her true identity is later revealed to be Alpina, a princess of a royal family hailing from another timeline with the power to control time, as well as the younger sister of Swartz. She eventually gains the ability to transform into Kamen Rider Tsukuyomi.]]

* EleventhHourRanger: [[spoiler:Tsukuyomi gains the ability to transform into Kamen Rider Tsukuyomi in #48 just before the final battle.]]

* AllLovingHeroine: At least when it comes to Sougo, being the first time traveler to believe that he doesn't have to become Oma Zi-O. Her confidence in him isn't limitless, though, and later events shake her confidence in her decision.

* AmnesiacsAreInnocent: [[spoiler:As Alpina, Tsukuyomi was fully on board with Swartz's plans which would have resulted in millions of deaths. But after losing her memories Tsukuyomi became an AllLovingHeroine who deeply values life and tries to prevent as much death as possible.]]
* ApocalypseMaiden: An indirect example, as it's established by the end of the Gaim arc that Tsukuyomi and Geiz's actions are helping bring about the very BadFuture they want to prevent. [[spoiler:It ''was'' a direct example initially, as Alpina was completely on board with her brother's plan until he betrayed her.]]
* BetrayalInsurance: [[spoiler:To give her a fighting chance against Swartz, Sougo and Tsukasa devise a plan where Sougo travels to 2068 to give Tsukuyomi a Blank Watch to store some portion of her powers, so that when the time comes where Swartz steals her powers he could not manage to take ''all'' of it, much like Tsukasa with his Decade powers. This, and further empowering from Oma Zi-O, allowed her to use her remaining powers to transform into Kamen Rider Tsukuyomi, to face Swartz as Another Decade.]]

*** Misora had powers [[spoiler: coming from a LivingMacguffin because said {{Macguffin}} is warning them about an alien planning to do an ApocalypseHow on Earth because it did said apocalypse on other planets ForTheEvulz]], while Tsukuyomi had powers [[spoiler: [[TimeMaster that manipulated time]] due to relating to the BigBad and also because she comes from another timeline.]] In addition, Misora was a GenkiGirl who wanted [[IJustWantToBeNormal to be a normal girl]], while Tsukuyomi has no need to be a normal girl due to wanting to SetRightWhatOnceWentWrong.
*** While Gentoku and Tsukuyomi are TheStoic that are sometimes NotSoAboveItAll, that maybe the only similarity. Gentoku intitially became the BigBad then DemotedToDragon due to being a ShellShockedVeteran, Tsukuyomi wanted to SetRightWhatOnceWentWrong because of the BadFuture that's going to happen. In addition, Gentoku became a Kamen Rider halfway to the series, [[spoiler: while Tsukuyomi became one before the GrandFinale.]]

*** Her starting out as a MysteriousWaif with no memories of her past, being a close companion and support to the series' hero, and her [[spoiler:being related to the series' BigBad]] bring to mind Koyomi from ''Series/KamenRiderWizard''. However, unlike Koyomi, who was [[spoiler:horrified by her father causing the first Sabbath and his planning to create a second one, Alpina actually went along with her brother's plan to destroy the multiverse until he wiped her memory.]] [[spoiler:In addition, while Koyomi only became a Rider in a movie, Tsukuyomi becomes one near the end of her series (which in turn parallels Mayu/Kamen Rider Mage).]]

*** Just as Sougo and Geiz can be compared and contrasted with Tsukasa and Kaito from ''Series/KamenRiderDecade'', Tsukuyomi is easily compared and contrasted with Natsumi Hikari from the same series. Both Natsumi and Tsukuyomi spend their series working to keep their series' main character from becoming evil and [[spoiler:become white-colored Kamen Riders at the end]]. But while Natsumi was a normal person thrust into insanity due to her taking in an amnesiac Tsukasa, [[spoiler:Tsukuyomi is a member of a royal family with time powers whose big brother kickstarted the plot. Also Natsumi became a Kamen Rider using a TransformationTrinket from an anniversary series in a movie, while Tsukuyomi becomes a Kamen Rider using her series' TransformationTrinket in said series.]]
* {{Deuteragonist}}: Of the second half of the show. Her connection and past with the main villain of the story is what sets up ''Zi-O's'' concluding arcs, cumulating her in [[spoiler:becoming a Kamen Rider herself.]]

* EveryoneCallsHimBarkeep: She was named Tsukuyomi by the resistance, due to her not remembering her real name. [[spoiler:Her true name is Alpina, but most of the cast still calls her Tsukuyomi even afterwards in the post-series spin-offs]].
* FaceDeathWithDignity: [[spoiler:Or Face Fading into Nonexistence with Dignity. While doing the former, she entrusts the futures of her and Sougo's worlds into Sougo's/Ohma Zi-O's hands with a small, peaceful smile on her face, in contrast to her brother Swartz's rage, disbelief, agony and excruciating pain over his failed XanatosGambit while he also fades into nonexistence. Of course, Sougo rewrites the timeline and revives her, so her death doesn't last long.]]
* FakeDefector: [[spoiler:In the final episode, she feigns defecting to Swartz’s side after receiving her Ridewatch. This leaves Swartz vulnerable to an attack [[InTheBack from behind]] by Tsukuyomi as he’s trying to escape back to his dimension, and gives Sougo an opening to destroy Swartz for good.]]

* {{Foil}}: She acts as one to Geiz, both coming from the future where Oma Zi-O rules with an iron fist and traveling back in time to stop his rise. But while Geiz came back to murder Sougo, Tsukuyomi attempted to peacefully persuade Sougo from gaining his powers. Geiz spends the early episodes eager to murder Sougo while Tsukuyomi tries to understand him and stop him from becoming evil. [[spoiler:Geiz and Tsukuyomi both have trouble seeing Sougo as Oma Zi-O due to his current kindness and how they deal with this shapes their later interactions with him. Tsukuyomi eventually trusted him so much that she thought it was impossible for Sougo to become Oma Zi-O and the realization of Sougo potential power and evil drives her against him compared to Geiz's whose initial distrust of Sougo ironically makes him more hesitant to go against him. They are also much more involved in Sougo's life than expected with Tsukuyomi being involved in the accident that killed his parents and being present in the moment that shaped Sougo's dream.]]

** [[spoiler:Tsukuyomi not knowing who Oda Nobunaga is while Geiz does makes more sense when it's revealed she has amnesia.]]
** In ''Heisei Generations Forever'', when Tsukuyomi loses her memories, she doesn't know why someone would call her Tsukuyomi. [[spoiler:This hints that her real name isn't actually Tsukuyomi.]]
** Tsukuyomi [[spoiler:being from another timeline is hinted when she and Tsukasa visit her past in the ''Kabuto'' Arc and they see her childhood home is a huge house in 2058. Tsukuyomi said the remaining people still alive under Oma Zi-O's rule, live in refugee camps which makes it odd that Tsukuyomi's family alone is living in luxury.]]
** In #15 of the Kamen Rider Zi-O Supplementary Plan where they discuss what would happen if Sougo did give up being Zi-O for good, [[spoiler:Tsukuyomi suggested she take over with the show being named Kamen Rider Tsukuyomi. In #48, Tsukuyomi becomes a Kamen Rider herself.]]
* GoodCounterpart: To Woz, who she competes with regarding their desired paths to guide Sougo towards, [[spoiler:and later to Swartz as his sister. Played with in the latter case, as she wasn't ''always'' good.]]
* GenderBlenderName: "Tsukuyomi" is the name of the [[Myth/JapaneseMythology Japanese lunar deity]], who is depicted as a male. [[spoiler:Fittingly enough, her Rider form features the moon.]]

* IJustWantToBeNormal: [[spoiler:Tsukuyomi didn't react well when she realized she had time powers in #31. Given said powers have only been shown to belong to Oma Zi-O as well as former and current ''Time Jackers'', it's understandable.]]
* IdentityAmnesia: [[spoiler:#31 reveals that she lost all of her memories from before she joined the resistance, Tsukuyomi isn't even her real name. She claims that she's fine with it now.]]

* MeaningfulName: [[spoiler:Going along with the time theme of the series, Alpina is a brand of Swiss watches. Swiss watches are known for being top quality to the point where they can virtually last forever, which references her being next in line as ruler in her own time.]]
* MoralEventHorizon: InUniverse example: She considers Zi-O II to be Sougo's, and seeing him use its time-manipulating powers to undo death and sculpt every event to his liking is enough to finally turn her against him. [[spoiler: [[{{Hypocrite}} It may have been a bad idea.]]]]

* NonLethalWarfare: In #1, she uses the Faiz Phone X to knock Sougo, [[Series/KamenRiderBuild Sento and Banjou]] unconscious so she can get the former back to 2018.

* OnlyKnownByTheirNickname: "Tsukuyomi" is the name the resistance gave her. [[spoiler:Late in the series, her true name is revealed to be Alpina.]]

* ProfessionalButtKisser: [[spoiler:She acts like one in the final episode to get on Swartz's good side to find an opportunity to kill him. It worked.]]
* ReallyRoyaltyReveal: [[spoiler:It turns out, Swartz and Tsukuyomi aren't only siblings, but in fact come from a currently mysterious royal family who are all TimeMasters, and Swartz was the one who sent Tsukuyomi to 2068. Tsukuyomi was going to become Queen if not for Swartz's actions.]]
* ReincarnationFriendship: [[spoiler:After dying thanks to Swartz, Sougo uses his time powers to reincarnate her as Alpina Tsukuyomi.]]
* RePower: [[spoiler:Tsukuyomi becoming a Kamen Rider returns her time powers that Swartz stole.]]
* SixthRangerTraitor: Subverted; [[spoiler:her apparent betrayal was so she could find an opportunity to kill Swartz.]]
* StudentCouncilPresident: [[spoiler:Her role in Sougo’s reset timeline]].

* TookALevelInBadass: She was pretty badass before but #38 reveals [[spoiler:she might have stronger time powers than any of the Time Jackers, even Swartz, being able to freeze a planet-sized asteroid in place. And then in #48 she becomes a Kamen Rider too.]]

* UnwittingInstigatorOfDoom: It's soon clear that Tsukuyomi and Geiz are enacting a StableTimeLoop and bringing about the very future they want to prevent. In a lesser example, [[spoiler:her presence on the bus crash in 2010 is what caused Swartz to damage the bus in a way that caused it to crash in the first place, killing all the adults while he escaped to 2019 with the kidnapped children.]]
** To an ''even lesser'' extent, [[spoiler:her very existence led to her being chosen as the heir over Swartz, who kickstarted the events in response. Though he of course is still at fault here.]]

** [[spoiler:Initially it was thought that Tsukuyomi caused the bus accident that killed Hiryu and Sougo's parents when she opened fire and caused the bus to crash. In reality, however, she was trying to protect Sougo from Swartz. While she was under the idea that Zi-O needs to be killed, she won't go so far as to kill him as a child]].
** [[spoiler:This was used against her in #47 where 2058 Swartz keeps his teenage appearance, knowing full well that Tsukuyomi cannot bring herself to shoot him despite his future actions and intentions]].

* LaserBlade: She can make a white one from her hands called the Luminous Fractor [[spoiler:and uses it to stab Swartz in the back.]]

* KnightOfCerebus: He's already [[TheDreaded an unstoppable force]] to begin with. The first thing he does in the ColdOpening is to singlehandedly wipe out every member of the LaResistance and going as far as to reduce their army to dust. #16 takes it to a more terrifying level when he beats Present!Sougo using [[Series/KamenRiderKuuga Kuuga]], [[Series/KamenRiderKiva Kiva]], and [[Series/KamenRiderRyuki Ryuki]]'s powers with little to no effort.

* CurbStompBattle: ''Every single fight'' this man is shown to participate ends in a one-sided slaughter. His introduction seen has him single-handedly wipe out the Resistance. When Sougo attacks his older self, Oma Zi-O doesn't put any effort and simply counters whatever Sougo throws at him by using the same Rider powers he uses. Even when Sougo obtains the Grand Zi-O Ridewatch, he ''still'' mops the floor with his younger self (though compared to their previous bout, Sougo manages to land a few hits on him). [[spoiler:Their third and final rematch subverts this, in that while Oma Zi-O is still superior in terms of power and experiences, he's hurt by Zi-O Trinity [[LoopholeAbuse on account of Trinity being a form he never obtained in his timeline.]] And then it's revealed even ''that'' isn't enough to hurt him]]]].

** [[Series/KamenRiderWizard Kosuke Nitoh]] is just Banjo [[spoiler:without the HalfHumanHybrid status]] but he has a monster inside his driver. Do the math.

* MoralEventHorizon: InUniverse example: She considers Zi-O II to be Sougo's, and seeing him use its time-manipulating powers to undo death and sculpt every event to his liking is enough to finally turn her against him. [[spoiler: [[Hypocrite It may have been a bad idea.]]]]

*** Misora had powers [[spoiler: coming from a LivingMacguffin because said {{Macguffin}} is warning them about an alien planning to do an ApocalypseHow on Earth because it did said apocalypse on other planets ForTheEvulz]], while Tsukuyomi had powers [[spoiler: [[TimeMaster that manipulated time]] due to relating to the BigBad and also because she comes from another timeline.]] In addition, Misora was a ShutIn GenkiGirl who wanted [[IJustWantedToBeNormal to be a normal girl]], while Tsukuyomi has no need to be a normal girl due to wanting to SetRightWhatOnceWentWrong.

** Just as Sougo and Geiz can be compared and contrasted with Tsukasa and Kaito from ''Series/KamenRiderDecade'', Tsukuyomi is easily compared and contrasted with Natsumi Hikari from the same series. Both Natsumi and Tsukuyomi spend their series working to keep their series' main character from becoming evil and [[spoiler:become white-colored Kamen Riders at the end]]. But while Natsumi was a normal person thrust into insanity due to her taking in an amnesiac Tsukasa, [[spoiler:Tsukuyomi is a member of a royal family with time powers whose big brother kickstarted the plot. Also Natsumi became a Kamen Rider using a TransformationTrinket from an anniversary series in a movie, while Tsukuyomi becomes a Kamen Rider using her series' TransformationTrinket in said series.]]
** Her starting out as a MysteriousWaif with no memories of her past, being a close companion and support to the series' hero, and her [[spoiler:being related to the series' BigBad]] bring to mind Koyomi from ''Series/KamenRiderWizard''. However, unlike Koyomi, who was [[spoiler:horrified by her father causing the first Sabbath and his planning to create a second one, Alpina actually went along with her brother's plan to destroy the multiverse until he wiped her memory.]] [[spoiler:In addition, while Koyomi only became a Rider in a movie, Tsukuyomi becomes one near the end of her series (which in turn parallels Mayu/Kamen Rider Mage).]]

** While both [[Series/KamenRiderDecade Yusuke Onodera]] and Woz are [[JerkWithAHeartOfGold jerks with a heart of gold]] that might be the only similarity. Yusuke, while selfish at worst, tends to be the same hero as his main counterpart, while Woz was always a TokenEvilTeammate until he made a HeelFaceTurn.

-->'''Black Woz:''' Please do not treat me as if I am a radar for Another Riders.

* AllLovingHero: {{Zigzagged}} at first. Sougo hates the idea of anyone getting hurt even willing to take a hit while unpowered to protect a child and he even reveals his dream of being a king is to protect everyone around him. But as the show goes on, Sougo is shown to not be as kind as he appears being an excellent manipulator and having moments of selfishness underneath it all. [[spoiler:His mirror self even lampshades that he's not as nice or optimistic as he appears to be. The last episode however this trope became played straight, as even after becoming Ohma Zi-O and defeated Swartz, he used it's abilities to destroy and recreate time and space, reviving both his comrades and the Time Jackers in the process in the rewritten timeline]].

** The previous Kamen Rider, [[Series/KamenRiderBuild Sento Kiryu]], was both an InsufferableGenius and a GeniusBruiser, while Sougo is an OrdinaryHighSchoolStudent who happens to be an EvilOverlord. While Sento designed his team's equipment on his own [[spoiler: based on an alien Driver]], Sougo is provided his own driver by Woz [[spoiler:that happens to be the predecessor of his future self's Driver]].

** Ryuga Banjo [[spoiler:is a HalfHumanHybrid who]] is an IdiotHero and can interact to Sento normally, while Geiz was an GeniusBruiser AntiHero who opposed Sougo due to his future and only halfway into the series did he warm up to him.
** Kaito was a shameless PhantomThief who [[{{Troll}} went out of his way to mess with everyone around him]], making him extremely unpredictable as a result. Meanwhile, Geiz is ''extremely'' straightforward in his approach of handling things [[FatalFlaw to a dangerous fault]], resulting him to be [[UnwittingPawn easily manipulated by other parties]] due to being so predictable. Distinguishing himself from [[PowerCopying Kamen Rider Decade]], Kamen Rider Diend's main power was [[EnemySummoner the ability to summon any past rider at his beck and call]], whereas Kamen Rider Geiz has the same exact main skill as Kamen Rider Zi-O - which being is to [[PowerCopying armor himself with the past Kamen Riders.]] Kaito is able to keep up with Tsukasa whenever they come to blows either physically or mentally but Geiz despite his efforts [[spoiler:before he got the [[SuperMode Geiz Revive Ridewatch]]]] is always weaker than Sougo on both of those fronts, much to his frustration. Kaito is openly friendly to Tsukasa (with WordOfDante saying [[AmbiguouslyGay the former "likes" the latter]]), but would regularly get in his way due to his own selfish desires while Geiz is openly antagonistic to Sougo but they regularly work together to protect the timeline, [[WhyCantIHateYou with Geiz unable to find it in himself to truly hate Sougo]].

** The previous Kamen Rider, [[Series/KamenRiderBuild Sento Kiryu]], was both an InsufferableGenius and a GeniusBruiser, while Sougo is an OrdinaryHighSchoolStudent who happens to be an EvilOverlord. Do the math.

* ContrastingSequelProtagonist: As with Sougo Tokiwa/Kamen Rider Zi-O and Tsukasa Kadoya/Kamen Rider Decade, Geiz is a big departure from Daiki Kaito/[[Series/KamenRiderDecade Kamen Rider Diend]]:
** Kaito was a shameless PhantomThief who [[{{Troll}} went out of his way to mess with everyone around him]], making him extremely unpredictable as a result. Meanwhile, Geiz is ''extremely'' straightforward in his approach of handling things [[FatalFlaw to a dangerous fault]], resulting him to be [[UnwittingPawn easily manipulated by other parties]] due to being so predictable.
** Distinguishing himself from [[PowerCopying Kamen Rider Decade]], Kamen Rider Diend's main power was [[EnemySummoner the ability to summon any past rider at his beck and call]], whereas Kamen Rider Geiz has the same exact main skill as Kamen Rider Zi-O - which being is to [[PowerCopying armor himself with the past Kamen Riders.]]
** Kaito is able to keep up with Tsukasa whenever they come to blows either physically or mentally but Geiz despite his efforts [[spoiler:before he got the [[SuperMode Geiz Revive Ridewatch]]]] is always weaker than Sougo on both of those fronts, much to his frustration.
** Kaito is openly friendly to Tsukasa (with WordOfDante saying [[AmbiguouslyGay the former "likes" the latter]]), but would regularly get in his way due to his own selfish desires while Geiz is openly antagonistic to Sougo but they regularly work together to protect the timeline, [[WhyCantIHateYou with Geiz unable to find it in himself to truly hate Sougo]].

* ContrastingSequelMainCharacter: Sougo as Zi-O is the inverse of Tsukasa Kadoya/Series/KamenRiderDecade in many aspects: both are anniversary Riders who deal with threats to all of the Kamen Rider multiverse - threats stemming from their own actions from their time as nearly all-powerful villains. Both are [[GuileHero Guile Heroes]] who [[PoorCommunicationKills cause tension with their allies as a result of their manipulations]]. Tsukasa's villainy was in the past, with him becoming a JerkWithAHeartOfGold, whereas Sougo's is in the future while he is currently a CloudCuckoolander. Tsukasa met AlternateReality versions of the other Riders, while Sougo meets the genuine articles but unintentionally corrupts them into alternate versions of themselves through his actions. Tsukasa was portrayed in his show as the most powerful Kamen Rider of all, and acted as a mentor who imparts lessons to the AR Riders that he meets, while Sougo is outclassed as a fighter and a hero by most of the other Riders that he encounters, and spends the show learning and growing from what they have to teach him.

* FaceDeathWithDignity: [[spoiler:Or Face Fading into Nonexistence with Dignity. While doing the former, she entrusts the futures of her and Sougo's worlds into Sougo's/Ohma Zi-O's hands with a small peaceful smile on her face, in contrast to her brother Swartz's rage, disbelief, agony and excruciating pain while he also fades into nonexistence. Of course, Sougo rewrites the timeline and revives her, so her death doesn't last long.]]

* BeCarefulWhatYouWishFor: He dreams of being a king. Sure enough, he finds out that unless he changes his ways, his future self is an omnipotent tyrant who rules the world with an iron fist. [[spoiler:Happens again in the Another Zi-O II arc since meeting Oma Zi-O, Sougo has done his best to avert that future and it finally happens in episode 41 when he is RetGone from history. But this allows Hiryu to take his place as an even worse Oma Zi-O.]]

** Killing the people that are close to him. [[spoiler: Good luck dealing with his Oma Zi-O form.]]

** Another Drive learns that the hard way after Sougo finally snaps and lays down a NoHoldsBarredBeatdown for [[spoiler: mocking Heure's death]].

* ABirthdayNotABreak: Another Hibiki rampages on his 19th birthday in episode 33 but he's perfectly fine with it. It's Woz that's the problem.

** [[spoiler:His "fight" against Another Den-O II using Grand Zi-O in Episode 40 is so one sided, it would be generous to even call it a curb stomp.]]
** We've seen Sougo's future self fight, however short-lived they were, but we get to see just how powerful Sougo can be [[spoiler:when he decides to go postal by donning the golden Ziku-Driver. He easily takes down the likes of Evolt and N-Daguva-Zeba, two of the most vicious enemies the Kamen Riders have ever faced (one being a PlanetEater and the other matching the likes of Kuuga Ultimate, the WorldsStrongestMan), with ''one blow''.]]

** [[spoiler: It eventually gets so bad that [[GuardianOfTheMultiverse Tsukasa Kadoya]] has to intervene so as to ascertain wether he should destroy the World of Zi-O or not to save the other ones. He has to.]]

* EveryoneHatesMathematics: Sougo is really bad at math, even needing to take a make up ''of'' a make up exam in episode 23 and falling asleep whenever he tries to study. [[spoiler:He even falls asleep '''during the exam''' in episode 24!]]
* FanBoy: Episode 10 reveals that Sougo is one for Oda Nobunaga, the first of the three unifiers of Japan, despite the fact that he was known as a Demon King for his brutal suppression tactics during the Sengoku Era, since the unification of Japan would have be impossible without him. This is also why Sougo don't have a problem about being called a Demon King as well, if Oda could unify Japan despite being a Demon King, than he would just have to be a benevolent Demon King.

* HiddenDepths: A less-than-positive version happens as the series progresses and it’s demonstrated that Sougo has all the traits of Oma Zi-O lurking beneath the "well-meaning but flaky teenager" exterior we saw at the start. He turns the Wizard arc into one gigantic BatmanGambit by manipulating Geiz and Woz to get what he wants while they're convinced it's in their best interests, in Episode 9 he casually [[CurbStompBattle curb-stomps]] Geiz, with the implication that he's always been that strong but held back because he doesn't like fighting. Manipulating people comes so naturally to Sougo that he does it ''subconsciously'': it takes being confronted by his Mirror World self to even realize it when he cons Geiz into committing suicide because it's just that instinctive to use people for his own ends.

** Deconstructed in the movie, [[spoiler: where it’s revealed that the fact he was so likeable made it easy for the other Riders to pass their powers to him, thus advancing Quartzer’s plans.]]

* ObfuscatingStupidity: Much like [[Series/KamenRiderOOO a previous king]], Sougo's kind and dopey nature belies the fact that he can be shockingly cunning and manipulative when he wants to be. Geiz realizes by the end of episode 8 that he spent the entire two-parter as a puppet on Sougo's strings, a two-parter where Sougo even manipulates ''Woz'' into giving him the information that he wants. Not long after, Sougo also reveals that he's a ''much'' better fighter than he's been letting on.

* RealityWarper: [[spoiler: He's subconsciously ''creating'' futures from the dreams he has.]] [[spoiler: The final episode has him channel Ohma Zi-O's power to destroy and recreate all the Rider Worlds, saving them from Swartz's apocalypse.]]

* StrangerInAFamiliarLand: Finds himself in this situation during [[spoiler: the Another Zi-O II arc]], due to being RetGone from history during that time.

* ThrowTheDogABone: Book dumb he may be, he finally passed a test for graduation in episode 24 with a score of 82%.
* TimeMaster: [[spoiler: At first it seemed that his time manipulation powers were the result of Ridewatches, it turns out that Sougo has had these powers at least since he was 10. If anything, the Ridewatches are merely tools to unlock more of ''his'' power rather than bestow anything on him. The powers he has shown are rewinding time, stopping time, rapidly aging something till it turns to dust, predicting a person's future actions, seeing the future in his dreams, even manipulating future timelines and seeing the past. ''Over Quartzer'' reveals that it was actually Swartz who gave him his powers, and SOUGO was the one who stopped the falling debris in #27.]]
* TooPowerfulToLive: Tsukuyomi believes this by episode 23. [[spoiler:Her seeing Sougo’s ability to reset the timeline reminds her too much of Oma Zi-O that she teams up reluctantly with White Woz. But the realization that Sougo can subconsciously manipulate the future to fit his dreams, deeply terrifies her that she's even more determined to stop him.]]

* BoringButPractical: Zi-O Trinity lacks the CombatClairvoyance of Zi-O II, monstrous speed of Geiz Revive, or various special abilities of Woz's Miridewatches and the Rider Armors, trading it all for a substantial increase in brute strength and access to their various weapons. [[spoiler: And it has the secret bonus of being able to hurt Oma Zi-O, as it never existed in his own timeline.]]

* CanonWelding: [[spoiler: Oma Form's summoning abilities are essentially Grand Zi-O's with this on top of them. While Grand Zi-O can summon the riders from any point in time, Oma Form can summon any rider from any form of Kamen Rider continuity, such as web-series, manga adaptations, and even stageshows.]]
* ChekhovsGag: One of Trinity Form's more humorous side-effects is to forcefully transport Woz and Geiz to Zi-O to transform, willingly or not. [[spoiler: This gets weaponized by Sougo in #46 to transport himself and Eternal into the Another World where Geiz and Woz are trapped in to destroy it and set everyone free.]]

* {{Depower}}: [[spoiler:As a result of the Ridewatches breaking in episode 47, the Grand Zi-O Ridewatch disappears]].

** [[spoiler: Zi-O Trinity can combine the powers of Zi-O, Geiz and Woz along with their respective WeaponOfChoice but also fuse the minds of the three riders sharing in one body.]]
** [[spoiler: The novel later has a unique Ridewatch for him to use that combines the powers of Zi-O, Geiz and Tsukuyomi alongside fusing the mind of the three riders in one body.]]

* PowersViaPossession: [[spoiler:By tapping one of the rider statues Grand Zi-O can summon a transparent version of the previous main riders then this transparent rider overlays Sougo to gain that rider's powers. He first showed this ability in episode 41 to gain Agito's power to defeat the Another AgitΩ summoned by Hiryu.]]

* StarPower: [[spoiler: Regulus, the constellation that shines to signify the Day of Oma, is used to form Zi-O Trinity.]]

* SuperMode: Kamen Rider [=GrandZi-O=], his final form accessed with the [=GrandZi-O=] Ridewatch. It wields the power of all 20 Heisei Kamen Riders. He contains statues of all of the Heisei Kamen Riders adorned on his body with Zi-O's making a crown. He can summon any version of all 20 primary rider by tapping the corresponding statue.[[spoiler: His extra final forms, Oma Form gives him powers of Oma Zi-O and then there's the actual Oma Zi-O he becomes ..]]

* VillainKiller: When [[spoiler: he becomes Oma Zi-O, he instantly kills some of the most powerful BigBad and/or FinalBoss characters in less than a minute, with Swartz/Another Decade barely taking that much more effort.]].

* NiceGuy: Overall very kind towards Sougo and friends. He took Sougo in after he lost his parents, accepts Tsukuyomi and Geiz pretty much as a part of family, is friends with Woz [[spoiler: long before the herald moves in]] and just loves cooking for anyone, who comes in, be their human or Imagin or anyone else.
* OmnidisciplinaryScientist: While Junichiro claims to be a clock repairman by trade, he's capable of repairing basically anything, up to and including ''time machines''. [[spoiler: He even fixes the ''Ridewatches'' for Sougo after they're broken and leaking history itself.]]

* ParentsAsPeople: Or in this case, "parental substitutes". In episode 27, he admits that he never scolded Sougo because he was scared, not knowing what to say because Sougo lost his parents so young. When he finally does advise Sougo that it's fine to feel sad, he nearly keels over from the fear afterward.
* PluckyComicRelief: While he's not without his own serious and touching moments such as giving advice to Sougo, generally his appearances lower the tension. [[spoiler: Even when he is trying to stab Sougo in #41, he does so with a radish.]]

* RunningGag: He never seems to be tasked with repairing a clock. Episode 7 has him note that he only seems to get a clock once every ''three months or so'' and that people apparently refer to his shop as a place for any repair job. In Episode 11 when Woz asks him to repair an actual alarm clock he's absurdly excited. So excited that he's pretty much ''blind to the world'' until he finishes working on it. Episode 39 takes the gag to its logical conclusion [[spoiler: with [[Series/KamenRiderDenO the Taros]] asking him to fix '''[[TimeMachine the Denliner]]''', trying to justify it by claiming that it's [[InsaneTrollLogic like a clock]]. And he ''succeeds'' and it doesn't stop there, in Episode 49, he was able to fix the '''[[TransformationTrinket RideWatches]]'''.]]

* UnfazedEveryman: He isn’t aware that Tsukuyomi and Geiz (and even his own nephew) are time travelers, but he accepts the fact that they’re living under his roof without a second thought. In Episode 3 he even makes the two of them ''bento'' lunch boxes to take to school, which prompts Sougo to remark on how accepting he is. Seeing Sougo come tumbling out of a mirror fazes him a little bit, but he shakes it off [[RefugeInAudacity by assuming that's just something kids do these days]]. [[spoiler:His reaction to Woz saying that Sougo is in space in episode 38 is make more food as Sougo has to be starving when he comes back. He even meets the [[Series/KamenRiderDenO Taros]] in their true forms without batting an eye, only stating they look more like Oni compared to Kyousuke.]]
* WontTakeYesForAnAnswer: In Episode 11, Woz asks him to repair an alarm clock. Because he's so used to it (see RunningGag), Junichiro automatically goes into his normal spiel about "Sorry, this is a ''clock'' repair shop" before realizing that the object in question actually ''is'' a clock. By that point Woz has apparently changed his mind and Junichiro practically has to pry the clock out of his hands just to work on it.

* InsistentTerminology: He always refers to Sougo as Zi-O instead of his name. This supplies Geiz's [[OOCIsSeriousBusiness out-of-character]] moment when [[spoiler: he calls Sougo by name instead in #16, showing how hard Sougo's decision to give up the Ziku driver and thus his dream hits him]].
* IChooseToStay: In Episode 46, his Another World (supposedly his ideal world) shows him having an honest heart-to-heart where he admits to Sougo that he wants to stay in the present and create a new future with Sougo's help. After being rescued, he tells Tsukuyomi that he's come to feel they belong in this era, and (grudgingly) thanks Woz for helping him figure it out.

* ProperlyParanoid: Geiz has a reason to be hostile towards Sougo, knowing fully that he will become Oma Zi-O and will not hesitate to put him down when that happens. Episode 16 finally justifies this the moment [[Series/KamenRiderDecade Tsukasa]] sends Sougo into 2068 and meets his future self in person.
* ProtagonistCenteredMorality: In episode 26, [[spoiler:Geiz sees Tsukuyomi in what looks like an attempt to kill Sougo as a child, which appears to be the cause of [[NiceJobBreakingItHero the bus crash that killed Sougo's parents along with a bunch of innocent people, including Another Zi-O's family]]. Is his takeaway [[HeelRealization the realization]] that their goal to change the future had gone too far, as well as the possibility that [[StableTimeLoop Tsukuyomi may have been the cause of Sougo beginning his path to becoming Oma Zi-O]] and [[MisplacedRetribution that Another Zi-O's grudge was her fault?]] No. He feels that [[ItsAllMyFault Tsukuyomi's death was his fault]] because he was hesitating in killing Zi-O, resulting in him gaining the resolve to become Geiz Revive. A very messed up moral there]].

* StolenMacGuffinReveal: Was revealed in Episode 13 that the Ghost and Drive Ridewatches he has (and supposedly all his other Rider equipment) were secretly stolen from Oma Zi-O prior to coming to 2018. [[spoiler:Episode 41 reveals that this is not a good thing, as Oma Zi-O can hijack the Drive powers of Grand Zi-O, because it came from ''his'' [=RideWatch=].]]

** [[spoiler: This holds up even after the timeline reset, with Geiz stating that he will defeat Sougo if he ever becomes a Demon King and Sougo fully counts on him to do so.]]

* UnwittingPawn: Reaching the point of [[DeconstructedCharacterArchetype deconstruction]]. Geiz's hatred of Oma Zi-O has made the man frighteningly easy to manipulate with almost every faction, including Sougo himself, using him for their own benefit multiple times. Geiz is capable of learning a ''little'' bit from this, and even manages to get one over on White Woz, but his stubbornness [[AesopAmnesia makes the lesson have a hard time sticking]]. Sougo even once manages to manipulate Geiz into killing himself, ''without meaning to'', because he's just that easy to fool. It is ''very'' telling that even when he manages to obtain Geiz Revive, the power that would allow him to avert the BadFuture and succeed in his mission, [[spoiler: he's STILL getting played like a chump by White Woz.]]

** Episode 7 indicates he and Woz were friends at one point. It's left in the air what NoodleIncident split them apart.
** Episode 29 officially reveals what had occurred between the two, revealing [[spoiler: Woz was the commanding officer of the Resistance unit that Geiz and Tsukuyomi were in. At some point, orders came through to have someone infiltrate and get close to Oma Zi-O, with Woz volunteering to do so. Whatever happened behind the scenes resulted in Woz defecting to Oma Zi-O, and deliberately feeding the Resistance false information and being the cause of many of his former comrades' deaths.]]
* WhyCantIHateYou: Platonic variant towards Sougo. He admits in episode 15 he has trouble seeing the present Sougo as Oma Zi-O just due to how different and nice Sougo is. Thus he's actually quite conflicted about his mission even begging Sougo to just throw away his belt so he doesn't have to kill him.

* AllYourPowersCombined: [[spoiler: His reincarnation Keito gets ahold of the Geiz Majesty Riderwatch in the V-Cinema movie ''Geiz, Majesty'' thanks to Daiki Kaito's Rider Cards, which combines the powers of the Heisei Secondary Riders the same way the Grand Zi-O watch does the Main Riders to defeat Another Diend/White Woz.]]

** [[spoiler: What [=GeizRevive=] turns out to be. According to Black Woz, the [=GeizRevive=] Ridewatch's power is caused by compressing and expanding time itself which puts a huge strain on his body, to the point that he experiences several nosebleeds, [[TearsOfBlood bloody tears]] and even spitting out blood after canceling his transformation.]]

* EleventhHourRanger: [[spoiler:Tsukuyomi gains the ability to transform into Kamen Rider Tsukuyomi in episode 48 just before the final battle.]]

* AmbiguouslyHuman: The reveal of her time powers put into question what she even is when Swartz says they're cut from the same cloth. [[spoiler:Episode 43 reveals that she ''is'' human, but from a different timeline than the rest of the cast.]]

* BetrayalInsurance: [[spoiler: To give her a fighting chance against Swartz, Sougo and Tsukasa devise a plan where Sougo travels to 2068 to give Tsukuyomi a Blank Watch to store some portion of her powers, so that when the time comes where Swartz steals her powers he could not manage to take ''all'' of it, much like Tsukasa with his Decade powers. This, and further empowering from Oma Zi-O, allowed her to use her remaining powers to transform into Kamen Rider Tsukuyomi, to face Swartz as Another Decade.]]

* CainAndAbel: [[spoiler:Episode 38 reveals she's Swartz's younger sister, thus the heroic Abel to his Cain.]]

* {{Deuteragonist}}: Of the second half of the show. Her connection and past with the main villain of the story is what sets up ''Zi-O's'' concluding arcs, cumulating her in [[spoiler: becoming a Kamen Rider herself.]]
* DieOrFly: Tsukuyomi awakens her time powers in episode 31 when an Another AgitΩ is about to attack her.

** In episode 15 of the Kamen Rider Zi-O Supplementary Plan where they discuss what would happen if Sougo did give up being Zi-O for good, [[spoiler:Tsukuyomi suggested she take over with the show being named Kamen Rider Tsukuyomi. In episode 48, Tsukuyomi becomes a Kamen Rider herself.]]

* {{Hypocrite}}: Part of the reason for her HeroicBSOD in episodes 31 and 32 is that she feels she's this because she turned against Sougo for his growing time powers only to learn that [[spoiler:she also has time powers. Potentially ''stronger'' ones.]]

* IJustWantToBeNormal: [[spoiler:Tsukuyomi didn't react well when she realized she had time powers in episode 31. Given said powers have only been shown to belong to Oma Zi-O as well as former and current ''Time Jackers'', it's understandable.]]
* IdentityAmnesia: [[spoiler:Episode 31 reveals that she lost all of her memories from before she joined the resistance, Tsukuyomi isn't even her real name. She claims that she's fine with it now.]]
* LetsYouAndHimFight: In Episodes 1 and 11, she gets an unwilling Sougo into fights by making threatening remarks while affecting a deeper voice, making it sound like he was the one doing the threatening. In the latter case, Sougo even remarks "Wow, deja vu..."

* MagicalComputer: In Episode 1, she pays an Edo-era shopkeeper by literally swiping coins off the screen of her tablet, which causes them to drop into the woman's open hands. In Episode 10, she uses it to heal Geiz's injuries.

* NonLethalWarfare: In Episode 1 she uses the Faiz Phone X to knock Sougo, [[Series/KamenRiderBuild Sento and Banjou]] unconscious so she can get the former back to 2018.

** If Episode 13.5 is anything to go by, she seems to have a crush on [[Series/KamenRiderDrive Ryoma Takeuchi.]]

* StudentCouncilPresident: [[spoiler: Her role in Sougo’s reset timeline]].

* TookALevelInBadass: She was pretty badass before but episode 38 reveals [[spoiler:she might have stronger time powers than any of the Time Jackers, even Swartz, being able to freeze a planet-sized asteroid in place. And then in episode 48 she becomes a Kamen Rider too.]]

** To an ''even lesser'' extent, [[spoiler: her very existence led to her being chosen as the heir over Swartz, who kickstarted the events in response. Though he of course is still at fault here.]]

** [[spoiler:This was used against her in episode 47 where 2058 Swartz keeps his teenage appearance, knowing full well that Tsukuyomi cannot bring herself to shoot him despite his future actions and intentions]].

* DepartmentOfRedundancyDepartment: In Japanese, his full name parses as something presumably meant to mean "[[NamesToRunAwayFromReallyFast Demon King Calamity Zi-O]]", but parses as "Maoh Oma Zi-O", and, taking into account the fact that "Zi-O" could potentially mean "time king", sounds effectively like "Demon King King Demon Time King". Episode 1.5 has Sougo point out the redundancy in the name and [[ComicallyMissingThePoint express dismay that his naming sense has gotten so cheap]].

* TheDogWasTheMastermind: '''Rider Time: Zi-O vs Decade''' has a scared child found in the middle of the woods by Tsukuyomi. [[spoiler: And then he [[VocalDissonance switches a dep per octave]], before he pulls out the Ohma Driver]].
* TheDreaded: Oh, ''most definitely''. When you've managed to kill HALF OF HUMANITY ITSELF before ruling over the rest with an tyrannic iron fist for the next fifty years with no one able to stop you, how can one not qualify as this? It has reached the point that any and all of his most prominent foes who wish to dethrone and/or have him killed had to travel back to ''before'' he even became Zi-O in the first place because his power is ''that'' damn terrifying and overwhelming to directly confront in any capacity. [[spoiler: Its quite telling that the Leader of Quartzer, otherwise known as the ''original Sougo Tokiwa'', also decided on using his younger self, knowing that his plans would most definitely fail if he tried using Oma Zi-O himself to reset the Heisei era.]]

** [[spoiler: Averted by Zi-O vs Decade, which makes him a CreepyChild]].

* HeelFaceTurn: [[spoiler: In the final stageplay (which takes place in the ''Over Quartzer'' timeline), he temporarily gets brought back and joins Sougo for one last battle against Hiryu, who became Another Oma Zi-O. [[CurbStompBattle They completly mop the floor with him.]]]]

* JerkassHasAPoint: Despite the BadFuture Oma Zi-O rules, he is correct that he did save the world; he just didn't make it a pleasant place to live in. [[spoiler:Episode 48 reveals that Oma Zi-O knows about Swartz and his plan. Thus the fact Oma Zi-O even exists means that Swartz, at least temporarily, failed to destroy the world. There's also the events of the Over Quartzer movie...]]
* KnightOfCerebus: He's already [[TheDreaded an unstoppable force]] to begin with. The first thing he does in the ColdOpening is to singlehandedly wipe out every member of the LaResistance and going as far as to reduce their army to dust. Episode 16 takes it to a more terrifying level when he beats Present!Sougo using [[Series/KamenRiderKuuga Kuuga]], [[Series/KamenRiderKiva Kiva]], and [[Series/KamenRiderRyuki Ryuki]]'s powers with little to no effort.

** [[spoiler: The only thing that could destroy him for good would be Sougo willingly giving up his driver permanently. During the events of the series, this happens, and the second time sticks.]]
* LoveRedeems: [[spoiler: In '''Rider Time: Zi-O Vs Decade''', his relationship with Tsukuyomi causes him to allow regular Sougo to kill him]].

* NotQuiteDead: [[spoiler: When Sougo reset the world, Ohma Zi-O, the true Sougo, was trapped between dimensions.]]

* PetTheDog: [[spoiler:Oma Zi-O empowers the blank Ridewatch his younger self slipped to Tsukuyomi in episode 48 despite feeling that it's pointless]].
* PhysicalGod: By the time he rules the world, he has fully mastered his power which include willful manaipulation of time and space combined with the entire powerset of the Heisei riders. He demonstrates some of Kuuga's and Kiva's abilities combined with enough raw power to one shot some of the strongest rider villains. WordOfGod confirms he had powers he hasn't openly demonstrated: like Kouta's reality warping, Evol's planetary destruction and galactic warping, Chronus' Pause, Genm's resurective immortality, various riders' super speed etc. etc. and he is literally all powerful. The finale and supplementary information goes even further, revealing the power to sense people in other dimensions, fight with infinite energy coursing through his body, teleport through space and time, age objects to death, manipulate fate, and destroy all of space and time within the Kamen Rider multiverse.
* PlanetDestroyer: [[spoiler:Episode 48 reveals that Oma Zi-O has the power to destroy space and time.]]

* PuppetKing: Shortly after he is ushered back into existence and begins to laugh, believing that everything is going as he has expected, a shadow is sitting behind Oma Zi-O's throne, hinting that for all his power Oma Zi-O may be subservient to someone else. [[spoiler:This is downplayed as episodes 27 and 28 reveals that Sougo is Swartz's candidate for Oma Zi-O, but later episodes show that the existence of Oma Zi-O means that Swartz's plan failed. And ''Over Quartzer'' reveals that he's also this to ''his own alternate self'' before he helped his younger self defeat his alternative self.]]

* SuperStrength: During the battle in Episode 1's ColdOpen, he drags a Time Mazine into his hands with his MindOverMatter powers and then ''hurls it.''

* TalentedButTrained: [[spoiler: Episode 28 reveals that Sougo received his time powers as a little boy, long before he ever had obtained his first Ridewatch. Oma Zi-O simply had over fifty years to master those same powers to the point that calling him invincible is quite frankly the most accurate thing you can say about his strength.]]

* WorldsStrongestMan: Possessing the combined powers of not just Heisei Riders, but '''ALL''' riders (Including ''Showa'' and ''Reiwa''), Oma Zi-O is bar none '''''THE''''' most powerful being in ''Kamen Rider'' lore. The one and only time he's seen truly fighting seriously, he obliterates the likes of [[PlanetEater Evolto]], [[PhysicalGod Gamedeus]], and [[PersonOfMassDestruction N-Daguva-Zeba]] [[OneHitKill in a single blow each]]. In the ''Zi-O Vs. Decade'' finale, [[spoiler: during a state in which a incarnation of him is at his weakest, he still manages to overpower Decade Complete 21, the upgraded version of [[SuperMode Decade Complete form]].]]

* HammyHerald: More obvious with Black Woz but White Woz also does this as shown in episode 26 [[spoiler:when Geiz awakens the Geiz Revive Ridewatch.]]

* BorrowedCatchphrase: In Episode 10, he adds Kousei Kougami's "Happy birthday!" at the start of his normal “ascension speech” when Sougo first uses the [=OOOArmor=].

* FaceHeelTurn: [[spoiler: He was once the leader of the Resistance faction Geiz and Tsukuyomi were under, who volunteered himself as a spy to infiltrate Oma Zi-O's ranks and find a plan of attack. This ended up being a trap set up by himself that killed most of his faction, with the surviving Geiz and Tsukuyomi baffled as to why he switched sides.]]

* HammyHerald: He essentially serves as Zi-O’s hype man, proclaiming his every action as if it came from a majestic tale. And he will make sure everyone within a five block radius can hear his proclamations. [[spoiler: He even hypes ''himself'' once he transforms into Kamen Rider Woz for the first time.]]

* HeroicBSOD: A PlayedForLaughs version happens in the Another Hibiki arc when he gets too focused on celebrating Sougo's 19th birthday that he focuses only on preparing Sougo's birthday causing Tsukuyomi to call out his efforts as just self-satisfaction. He spends the from latter half of episode 33 to the latter half of episode 34, hilariously depressed.

** A more positive example happens in episode 40 when [[spoiler:Sougo gains [[SuperMode Grand Zi-O]] and instead of making a grand speech like usual, he's so overjoyed he decides to just enjoy Sougo showing off his new power.]]

* PetTheDog: Despite his tense relationship with Geiz and more detached one with Tsukuyomi, episode 43 shows he does cares about them. [[spoiler:He dropped his cover and rushed in to save Tsukuyomi when he saw Swartz was stealing her powers and lightly and playfully hit Geiz on the chest after the timeline was fixed with a big smile on his face.]]

* ScrewDestiny: [[spoiler: He rips apart the Oma Advent Calendar that Barlckxs gave him to guide Sougo to become Oma Zi-O in ''Over Quartzer'', declaring to Barlckxs that his loyalty lies with Sougo as his true liege-lord.]]

* TookALevelInBadass: [[spoiler: After hijacking the power of Kamen Rider from White Woz, he finally becomes a Rider in his own right.]]

* WeUsedToBeFriends: He and Geiz were friends at some point. Now they can barely tolerate being in the same room as each other. Justified, since Woz [[spoiler: betrayed the Resistance to Ohma Zi-O]]. This crushed the Resistance underfoot and kick-started Geiz and Tsukuyomi's mission to the past.

** Case in point? [[spoiler: Even when White Woz has managed to bring about the creation of [[TheKingslayer Geiz Revive]], White Woz still finds himself OutGambitted by his counterpart who manages to ''steal'' the power of Kamen Rider Woz from him by turning [[RewritingReality his tablet's powers]] ''[[HoistByHisOwnPetard against him.]]'']]

* AlternateSelf: [[spoiler:The White Woz that returns in episode 45 isn't the same White Woz that the show had been following. This White Woz comes from an alternate world created by Another Decade, where he was successful; as such, he retains the Kamen Rider Woz powers. Like the original White Woz, he had a HeelFaceTurn and now shows genuine concern for Geiz, actively aiding the heroes in rescuing him from Swartz's Another World]].
* AmbiguouslyEvil: White Woz claims to be on Geiz's side, and represents a future that ''sounds'' like an objectively good thing, but since it's supposed to involve Geiz ''killing'' Sougo on the Day of Oma, his future might not be as bright and shiny as he claims it is. [[spoiler: The "ambiguously" part is dropped entirely when it's revealed that Geiz Revive is designed so that it will kill Geiz, and that White Woz was answering to Swartz all along.]]
* AntiVillain: Being the {{Herald}} for Geiz Revive and to make sure Geiz defeats Oma Zi-O, this doesn't stop White Woz for committing even more villainous acts to deal with a greater evil. [[spoiler:Episode 27 throws out the "anti" part.]]

* BlatantLies: [[spoiler:Episodes 27 and 28 reveals he has been lying from the start and wasn't even loyal to Geiz at all. White Woz has been working with Swartz from the start, just going about their shared goal from a different plan. White Woz reveals that Geiz Revive killing Sougo wouldn't bring about the perfect future he promised and might only bring about a future that he wants as he laughs at the future casualties as a result.]]

* BreakTheHaughty: Episode 27 ends with [[spoiler:Black Woz stealing his Kamen Rider powers from him with Heure's help.]]
* TheBusCameBack: [[spoiler:Despite being erased from time, he's summoned from another dimension by Swartz/Another Decade at the end of episode 45, in replacement of Geiz who was sent to the dimension he was pulled from in his place. It was a brief return as he willingly saves Geiz at the cost of his life.]]

* ColdBloodedTorture: In episode 28, [[spoiler: White Woz tortures Heure by stomping him to understand what Black Woz is planning.]]

** [[spoiler:In episode 27, he loses his power to transform into Kamen Rider Woz thanks to Black Woz and Heure.]]

* EvenEvilHasStandards: PlayedWith: Despite everything about him, even he's horrified when he learns that Black Woz [[spoiler: Gave Sougo the Zi-O II watch, and thus the power of Oma Zi-O, early.]]
* EvilAllAlong: [[spoiler:Episode 28 reveals he has been working with Swartz since the start.]]

** Episode 27 reveals that [[spoiler: he calls Geiz "my savior" because Geiz' purpose is to be ''his'' personal savior by ensuring his timeline becomes reality - White Woz knows that Geiz cannot handle Revive and will not survive the battle with Sougo.]]
** Funnily enough, this same trope [[LaserGuidedKarma comes back to bite him]] ''in the very same episode'', by his own hand no less! [[spoiler: Specifically, when writing down that the power of Kamen Rider Woz would return to Woz...failing to specify ''[[ProphecyTwist which]]'' [[HoistByHisOwnPetard Woz it would return to]].]]

* {{Foreshadowing}}: White Woz's description of the Geiz Revive timeline foreshadows [[spoiler:Swartz/Another Decade's Another World.]] Specifically in Episode 21, White Woz has stated that his future is a "everlasting peace as if time itself has stopped". And in episode 46 [[spoiler:he mentions that the [[LotusEaterMachine Another World]] is [[IRejectYourReality "A place of repose,]] [[GroundhogDayLoop where time stands still for eternity".]]]]
* GoodIsNotNice: Be it threatening to kill a child, admittedly one of the Time Jackers, in order to gather information, or treating everyone around him like a disposable pawn, this Woz is nothing short of villainous in his behavior. However, he seeks what appears to be a good future, or at least a better one than the reign of terror of Oma Zi-O. [[spoiler: This goes straight out the window when it becomes clear that the future of Geiz Revive is a future that's mostly for White Woz's own benefit.]]

* HateSink: White Woz's motives might be justifiable at best. However, he is but a nasty piece of work who goes his way to be as despicable as possible, making Heure and Black Woz himself all the more sympathetic. [[spoiler:And any sympathy he may have had goes out the window in episode 28, when it is revealed that his true allegiance is with Swartz. Eventually he later grows out of it after Sougo convinces him to return the Zi-O II and Geiz Revive Ridewatches, as well as giving Sougo the new Zi-O Trinity Ridewatch, before he finally fades away while he warned his original timeline self of Swartz's schemes.]]

* HisNameIs: [[spoiler:In Episode 46, he tries to warn Geiz about Swartz's ultimate goal before he fades away, only to be interrupted (and prematurely killed) by Swartz.]]
* HoistByHisOwnPetard: ''[[DidntThinkThisThrough Hoo boy]]''. Next time you have to write something in your tablet, make sure that you [[spoiler: specify which Woz you're taking about.]]

* JerkWithAHeartOfJerk: He has set up as a [[JerkWithAHeartOfGold jerk with a heart]] of [[BlackAndGrayMorality moral ambiguity]] with good intentions for the future. Then he gets Futuring Quiz and uses its powers to gleefully ''torment'' Tamotsu Douan/Another Quiz with a pair of cruel questions seemingly hand-tailored to KickTheDog while laughing.[[labelnote:*]]"Your work will be recognized" [[AllForNothing (False)]], "Your family will, in time, stop caring about you" (True)[[/labelnote]] [[spoiler:Episode 27 even reveals that his UndyingLoyalty to Geiz is to a certain extent. He only cares that Geiz kills Sougo so his timeline comes to pass and doesn't truly care about Geiz himself, happy to let Geiz Revive slowly kill his "savior".]]

* SociopathicHero: Be it manipulating Sougo and Geiz to do as he wishes, informing Geiz he has no choice about becoming the savior Woz wants him to be, or [[PayEvilUntoEvil inflicting cruelty upon the Time Jackers]], White Woz is smug and uncaring to everyone around him, [[PerpetualSmiler all with a smile on his face]]. [[spoiler: And then episode 27 reveals that he was never a "hero" to begin with.]]

* UnderestimatingBadassery: For all of his ability to control the flow of events, this man has very much paid the price for not taking into account the resourcefulness of [[AlternateSelf Black Woz]]. Firstly, when the latter has managed to give Sougo the [[TheDreaded Zi-O II RideWatch]] without White Woz even realizing this until it was too late. Secondly, but much more importantly, [[spoiler: with Black Woz being able ''to steal'' the powers of Kamen Rider Woz '''[[RefugeInAudacity literally right in front of White Woz's face.]]''']] That last point leaves White Woz screaming in pure anger at what just happened.
* UndyingLoyalty: White Woz claims to be Geiz's loyal servant like how Black Woz is Sougo's, [[spoiler:episode 27 reveals that it's a lie and he's only using Geiz. But the White Woz summoned from Swartz's Another World in episode 45 reveals he is actually loyal to Geiz, even creating a plan to save Geiz at the cost of his life.]]

* UtopiaJustifiesTheMeans: He describes the future without Oma Zi-O as a peaceful utopia and he will do anything to achieve it, even going against his messiah or killing defenseless civilians. [[spoiler: Of course #27 reveals that said "utopia" is only such for a select few, potentially even ''[[ItsAllAboutMe just him.]]'']]

* ChainReactionDestruction: As Revive Goretsu, Geiz's strikes with his chainsaw are so powerful that they produce this effect in a line away from him.

* ImperfectRitual: [[spoiler:Grand Zi-O was formed without the Drive Ridewatch from Sougo's timeline which led to Oma Zi-O taking control of Drive's powers in their duel since the one Geiz stole is still technically ''his''. Once obtained, this is subverted as Sougo remains Grand Zi-O for the remainder of the show after the movie. But in the finale it is revealed to be a double subversion, as Oma Zi-O is NOT the unification of the powers of all 20 primary riders, but the unification of the powers of EVERY Heisei Rider, making Grand Zi-O not just an incomplete version of the form but only unified a small fraction of the potential powers.]]

* HeroKiller: Inverted when [[spoiler: he becomes Oma Zi-O, instantly killing some of the most powerful BigBad and/or FinalBoss characters in less than a minute, with Swartz/Another Decade barely taking that much more effort.]]

* UnskilledButStrong: Compared to his future self, Sougo is shown to possess much less control over his time-manipulating powers, which sometimes suffer from PowerIncontinence as a result. By the end of the show, he's essentially conquered this flaw.
