Interestingly enough, if you listen closely to the transformation sound of Zi-O, it uses a high pitched tone for the phrase Kamen Rider, but then takes a deeper turn when it says Zi-O. Maybe because Zi-O in the future is the Demon King of Time?
More importantly is the part where it says Kamen Rider. With Geiz it's auto-tuned, which goes along with his digital motif, while Zi-O's is mostly unaltered. The part where it announces Zi-O or Geiz carries the same dropped tone, as if being a "stopping point" for the 'Kamen Rider'.
One small thing to note; look at the design of Zi-O's face katakana and their placement. Note how the イ character's tip points out beyond the visor area, so it joins the minute and hour hand in the top. It's supposed to represent the second hand!
While the choice of Kento Shimoyama as head writer may seem odd considering how much maligned the other series he wrote, Shuriken Sentai Ninninger, was, but after Ninninger he also wrote a Web Video series for Kamen Rider Ex-Aid which also was the only thing he wrote for the Kamen Rider franchise until Zi-O. The Web Video series in question? Kamen Sentai Gorider, another crossover special between past and present Kamen Riders. Considering the positive reception Kamen Sentai Gorider got especially towards the characterization and use of the past riders, it makes sense why Toei chose him as head writer for this crossover series. And before he started to wrote Zi-O and Ninninger, he wrote some episodes of Kaizoku Sentai Gokaiger, an anniversary season and a fan favorite among the fandom.
Sougo's henshin pose, where he moves his arms in a counterclockwise fashion, could be seen as him turning the clock back in order to use his and the past Rider's powers.
The same could be said of the Zikū-Driver when spun.
Interestingly, when transforming into his default state he spins the Driver clockwise, indicating time moving forward. A sign that he's advancing toward the Bad Future, or that he's making his own fate?
Tsukuyomi taking the Time Mazine into the age of the dinosaurs to hide from Geiz, and other time travelers in general, actually makes perfect sense - it's an age Older Than Dirt where no humans existed to record history. Everything we've learned about the dinosaurs from paleontology will at best give a rough estimate as to what century they existed in. Even if Sougo left footprints that were unearthed by paleontologists, it would still take Geiz ages to search through the massive window he could be in. As for how Tsukuyomi could make the return trip... well, the present day and her own time are likely recorded in the Time Mazine, like bookmarks on Mozilla Firefox or something.
Each of the Another Riders has powers and even identities that invert the Rider theyre based on.
Sento Kiryū is a brilliant scientist, gaining his power from purified Smash essences that turn Smash back into humans. Another Build is an athlete that gains his power from human essences that he gains by turning them into Smash Fullbottles.
Emu Hōjō is a gaming doctor who was saved from death as a child and now helps people beat games that have infected them with the Bugster Virus. Another Ex-Aid is the parent of a dying patient who infects people with the Bugster Virus by dragging them into an unbeatable game.
Gentarō Kisaragi believes wholeheartedly in the Power of Friendship and willingly gave up his powers to inspire another to become a hero. Another Fourze, on the other hand, is a loner who strongly desires power and freaks out when his original power as Another Faiz is fading away.
Takumi Inui became a monster after dying and attempted to use his powers to save students from the massacre at Ryūsei he ultimately failed to stop. Another Faiz became a monster after his friend died and used his powers to kill countless girls for the sake of his friend. In fact he's actually closer to Masato Kusaka since he made a Deal with the Devil to bring Mari Back from the Dead, which was his own fault.
Haruto Sōma refused to give into despair and become a monster, instead choosing to fight and become a shining light of hope for others who find themselves in despair. Another Wizard, on the other hand, used his powers not to help others but rather to fulfill his own hopes and dreams. Ultimately, he soon went over the Despair Event Horizon when his hope was crushed and became a monster. Also, notably, his magic powers are activated by simply announcing the spell's name, without saying "Please", as if he's a more rude and selfish version of Haruto.
Eiji Hino was a humble man who didnt desire much of anything and while having the powers of a greedy evil king, he used that power to do good everywhere he wandered around the world. Another OOO is Kuroto Dan, quite possibly the man with a personality most opposite Eijis, and the evil one who the powers of Ex-Aid came from in the first place.
Additionally, Eiji was a man with absolutely no desire, but gaining the power of Kamen Rider OOO, led to him (re-)discovering his desire to help people no matter where they are. Kuroto, on the other hand, lost sight of all his original goals once he became Another OOO, and became an aimless tyrant who only rules for the sake of it.
Kōta Kazuraba started out humbly as a member of Team Gaim, only to grow out of it and eventually become a god that saved earth from Helheim by removing it to another planet. Asura was a member of Team Baron who was kicked out, only to gain the powers of Another Gaim and use the powers of Helheim to usurp Kaito and keep his teammates in line. Opposing Kōta's status as a god also fits his name, as an angry deity obsessed with and solving all his problems with violence.
Takeru Tenkūji became a ghost after death, offered to revive himself by an all powerful god, only to sacrifice that opportunity for the sake of others and to teach them the value of life. So in a way, Takerus life burned brightly. Makimura refused the opportunity the Time Jackers gave him to save his own life, burned brightly during his last moments, only to become a puppet for Another Ghost in death, sustaining his own lifespan by consuming the souls of others. Which in a way, is taking the flames of anothers life so that they can continue to burn brightly.
Ryōtarō Nogami is an everyday man who gets drafted into the war against Imagins but gladly allows the benevolent ones to possess him to fight them. Ataru Hisanaga however is a boy who gets possessed to become Another Den-O, but while being similar to Ryōtarō, who's actually in control is different: the Taros are benevolent Imagin who wants to coexist with humanity, while the Another Den-O Watch possesses Ataru as an unwilling host.
For Another Den-O II, Takuya Endō is a young man who blamed his sister's boyfriend for her death and came up with a plan to steal the DenLiner to stop that from happening. Ryōtarō looked up to his sister's fiancé like an older brother, to the point where part of the reason he remained a Kamen Rider was to reach out to him and even gained the respect of the younger Yūto despite their differences.
Shōtarō Hidari and Philip are men who would often use the former's late mentor's "count up your sins" motto and are eager to protect the smiles of their city, Fūto. Another Double on the other hand is Tid's second-in-command and leads an army of combatants to attack innocents, effectively making an entire towns people crying in peril.
Yūsuke Godai was a man who desired to protect the smiles of all no matter what, and in a meta sense, represents the revival of the Kamen Rider franchise into a new era. Tids goal is to transport all the riders to the real world and ultimately bring the end of their era and all those they protected. Absorbing Shingo to become Another Ultimate Kuuga is also a twisted form of Yūsukes motivation in life, using the smile of a fan of Kuuga to evolve further.
Before he became Kamen Rider Shinobi, Rentaro Kagura was a kind man who sought justice, but was too weak to be effective. As Another Shinobi, his sense of justice still remains, but he's far too effective at getting it.
Mondo Dōan's fighting style as Kamen Rider Quiz necessitates he show his opponents all the knowledge he has over them to attack, all of which are done as flashy and attention-grabbing as possible. Another Quiz, his father, was likely just as intelligent, but his inability to produce results meant he never got the fame nor recognition he felt he deserved, ultimately dying without anyone remembering him.
Shinji Kido is a kind reporter who fought to keep anyone from dying in the Rider War. Another Ryūga is the cruel Dark Shinji, his literal mirror image who instead attacks former readers of ORE Journal for a petty grudge.
Additionally in a benevolent way, Another Ryūga is an opposite of the original: in Kamen Rider Ryuki Episode Final, Dark Shinji deceived Shinji to become one so he can exist outside the human world with no setbacks. While Another Ryūga indeed hunts former followers of ORE Journal out of petty revenge, Sougo revealed that in the end, Dark Shinji only wants recognition from his original self and returns to being Shinji's reflection once accepting his defeat.
For Another Ryūki, Tatsuya is a person that started a murder game for the sake of his dying girlfriend, Sara, acting a lot like Shirō Kanzaki while Shinji was forced into the Rider War but is dedicated to ending it peacefully.
Rento Makina is a Ridiculously Human Robot hero who fights for the liberation of humanity in the future of 2121. Another Kikai is a mindless parasite that searches for organic hosts to dominate their will, and rather than machinery, is made from wood. Its host Heure meanwhile, offers contracts that surrender the free will of most of the hosts, aiming to bring humanity to its knees with a new Demon King.
Sōgo Tokiwa desires to be a king to protect everyone around him and gains the previous Riders' powers by meeting them and learning from them. Hiryu Kakogawa instead only cares about defeating Sōgo to the point of turning innocent people into Another Riders for more power and gains the Another Riders' powers by assaulting their original owners.
Kazuma Kenzaki was a kind-hearted person who willing gave up his humanity by turning into an Undead in order to see his friend Hajime have a good life and save the world. Amane, who was a bratty kid in Blade (♠), was forcibly turned into a monster by people who want to see the world burn, and went looking for Hajime, the only person she respected. Whereas Kenzaki distances himself from Hajime for the betterment of humanity, Amane's action of tracking Hajime makes her an Unwitting Pawn of attracting two Jokers together to bring the Battle Fight to a definite end, therefore dooming mankind once more.
The Seed of Αgitω was created by the Overlord of Light to allow humanity to evolve past the Lords above them and give them a fighting chance. The Another Αgitωs spread among humans like a virus, dooming humanity to become mindless beasts under the control of the Time Jackers and ensuring the suppression of the human race.
In regards to the individuals, Shōichi Tsugami is an amnesiac who eventually embraces his current identity and achieve a simple life even though he's a product of human evolution. Patient Zero of Another Αgitω completely lost his identity after receiving the Another Αgitω Watch and became a mindless creature following the Time Jackers orders.
This Another Αgitω is also the antithesis to the original Another Αgitω, Kaoru Kino. When the former surgeon became Another Αgitω, he became disillusioned and detached from reality, to the point he thought he alone could defeat the Unknown threats and ultimately trying to defeat Shōichi before his encounter with Ryō Ashihara/Kamen Rider Exceed Gills, which leads to his eventual change of heart; fighting alongside with the Riders until his last breath. This Another Αgitω is a reflection of what Kino could have become if his Seed of Αgitω was corrupted by his long-lasting psychological and emotional breakdown, as well as his grandiose delusions.
Hitoshi Hidaka was the oldest and most trained of the Oni Riders, and was a firm believer in hard work to achieve greatness. Tsutomu Tsuzumiya is a young man in training to become an Oni, but was forced to take an easy way to achieve that goal (an Anotherwatch).
In addition, Tsutomu also contrasted with Hitoshi's disciples: Asumu Adachi and Kyōsuke Kiriya.
Asumu is a humble youth who willingly decides to live a normal and peaceful life as a doctor rather than being an Oni at the end of Hibiki. Tsutomu on the other hand, is more than happy to mention his ambition of becoming an Oni and even bragged about his master.
Ironically, both Kyōsuke and Tsutomu shares many similarities: in addition for being ambitious, they also willing to take underhanded methods to get what they want. Thankfully, Kyōsuke is aware of this and as such he became much more matured and responsible than he was in Hibiki. Tsutomu, as Another Hibiki, becomes a twisted reflection of everything what Kyōsuke was in his home series.
Wataru Kurenai was an introvert in self-imposed isolation who eventually grew to rise up to the rank of Fangire King to ensure the Demon Races could find a way to co-exist peacefully with humanity, along with protecting his half-brother Taiga Nobori. Yūko Kitajima is a woman who was incarcerated with the grand goal of becoming the queen of the world to change it under her own vision by force. She also quite prideful with her newfound power as Another Kiva, just like Taiga and by proxy his father the King/Bat Fangire.
In addition, Yūko also contrasted with Wataru's relatives and significant others: Otoya Kurenai (his father), Maya (his mother) and Mio Suzuki (his deceased love interest).
Otoya was an eccentric violinist and charismatic womanizer who is greatly remembered and respected by his peers, such as Ōmura, Jirō and Maya, to the point they referred him as a "great man". While sometimes he inadvertently ruining the lives of others with his antics, he is more than willing to give his hands to change their lives for the better. Yūko, on the other hand, is a schizophrenic individual who believes herself to be a rightful ruler and is an pathological liar who feigns being wrongly convicted. Her relationship with her ex-boyfriend is reminiscent to Otoya towards Yuri: while Otoya willingly broke up with Yuri Asō after he confessed that he fell in love with Maya, Yūko killed her former lover's girlfriend after they broke up and even go so far as to attempt to kill his fiancée during their wedding.
Like Maya and Mio, Yūko was granted the power and responsibility as a Queen to to judge and execute others. However, while Maya and Mio don't possess ill will towards humanity and redeem themselves in the end, Yūko, though her death resembles Mio's death, is not the true identity of Sougo's first love.
Sōji Tendō was a talented man who saw himself as nothing short of a god walking the path of heaven, yet never had any real goal, as he was the best of them all. Despite that, he remains idealistic and Kagami who become Kabuto's temporary successor maintains the same outlook on life despite all that has happened even after Sōji left for France. Another Kabuto is Sō Yaguruma, whose fall from grace gave him a nihilistic outlook on life after becoming obsessed with defeating Tendō, resulting in him deciding to take a life of what he viewed as a road down to hell. In addition, while both of them have strong feelings towards their sister/brother figures, Tendō vows to protect both the world and his sister(s) Hiyori and Jūka, whereas Yaguruma shows no hesitation in leaving the world as long as he can be beside his "brother" Kageyama.
Almost all Riders have powers that are either evil in nature or are used by the evil they fight. And sometimes, using that power leads to them becoming the same monsters they fight. However, Riders have the willpower to fight against the evil and remain human at heart. The average human being? Not so much. So it should come to no surprise that when an average human uses a Riders powers, theyre corrupted by it and become monsters.
Not only that but Another Build is a basketball player who is given Builds powers. Builds powers are based in being a scientific genius and yet theyre given to somebody, an athlete, with the least compatible traits? Seems not only do you need the morality and willpower but also the personal traits of the Kamen Rider too.
Why is one of Geiz's motifs a butterfly? Butterflies represents change, and things change as time goes by. Its also a reference to the "butterfly effect".
Geiz uses the Ghost Ridewatch. Not only is he nothing like Takeru, who values life due to having died and would never take a life, but Geiz might also see it as justice that Zi-O is taken out by the grudges of those he killed.
The first two Ridewatches Geiz has are Drive and Ghost. His henshin pose combines the arm movements from Ghost and the wide stance of Drive.
Giving a basketball player Builds power makes some sense considering Builds default form is RabbitTank. A basketball player would be strong and capable of jumping great heights.
Another Build notes (with disappointment) that Karate and Tennis are not a Best Match. Aside from the fact that both are vastly different sports (Tennis is a ball sport; Karate is a martial arts that involves hand-to-hand combat), both would likely count as Biotic Fullbottles if they were to be used in actual Best Matches, since they'd likely be representing the player of each (Tennis Player for Tennis, Karateka for Karate), and with the exception of RabbitRabbit and RabbitDragon (which were very special cases), you can't make a best match with 2 Biotic Bottlesnote same goes for Abiotic Bottles, which also had an exception in the form of TankTank.
As for why Swimmer and Archer is a Best Match? Because of the way Evolt set up the Best Match system, an archer would be capable of shooting and killing a swimmer in the water. Geiz even stops Another Build from using his swimmer powers with the Zikan Zax's Yumi Mode.
Kind of a late one on Another Build, but one of his attacks that was about to hit Geiz and Tsukuyomi until Sougo deflects it in a Big Damn Heroes moment? That attack was a baseball. It highly implies he might have found a Best Match for Baseball at some point offscreen.
Quite a few Kamen Riders' Final Forms have gold as their main color scheme (Blade (♠), Kiva and Ex-Aid) and Ōma Zi-O's suit is gold rather than Zi-O's silver and has lots of extra parts attached to it. Ōma Zi-O's suit is Zi-O's Final Form! (or rather, what his Final Form could be if he becomes Ōma Zi-O...). It's also fitting those Final Forms have traits that Ōma Zi-O also possesses. Blade King Form (♠K) and Kiva Emperor Form both represent rulers as King and Emperor respectively and Ex-Aid Muteki Gamer represents invincibility which also fits since it's stated Ōma Zi-O is the unmatched Evil Overlord of the future.
And a few Kamen Riders who are the Big Bad tend to have a form that is gold plated with red eyes, just like Ōma Zi-O.
Anotherwatches don't appear to have turning faces like Ridewatches and thus do not display a date or symbols. Makes sense, given that Ridewatches embody Kamen Riders of past while Anotherwatches are for Another Riders that have yet to be created.
In the opening, there's a section where Zi-O and Geiz jump down some stairs while their face characters extend out, showing where they're going to go. It's actually a subtle reference to Nude Descending a Staircase, No. 2, a famous portrait which portrays a character at multiple points in time simultaneously. Fitting for a time-based series.
It's also a reference to their Rider Kick finishers, which involve their mask and foot characters creating a line of trajectory (or in Zi-O's case, keeping the monster in place). Zi-O's finisher even has his characters lighting up in order of pronunciation, so it literally spells "Rider Kick".
In the opening, Zi-O and Geiz are shown at first riding their bikes and dodging attacks together, but in the closing scene, they are suddenly fighting each other. This perfectly reflects their relationship in the series, Geiz is willing to fight together with Zi-O and protect the timeline, but if Sougo shows any sign of becoming like Ōma Zi-O, Geiz is willing to kill him immediately without missing a beat.
Funny it may be, but Geiz using his own name as his Rider name makes sense. He's from a Bad Future engulfed in war and strife, why the hell would he care about using a cool pseudonym?
Why did Another Build get excited to see Banjō, enough to say he and itself are a Best Match? Because as far as it knows, it's Kamen Rider Build and Build's closest partner and friend, the one he can trust to have his back in a fight, is Kamen Rider Cross-Z.
Heure transforms the same basketball player into Another Build rather than simply turning somebody else into Another Build. While it's a bit soon to confirm, it implies only one person can transform into a specific Another Rider. It's much like how the previous Kamen Riders could only be portrayed by their original actors and trying to change that led to some complaints...
Of course the graph created when Sougo uses Vortech Time Break isn't any complicated equation like Sento's. Sougo isn't smart enough to create any fancy equations like Sento can so a simple line graph is all he could think up.
Sougo has traits similar to the past Riders such as...
Sōji Tendō: Underneath the meek and nice guy personality, Sougo has an ego similar to Tendō's, stating it's his destiny to become someone great.
Why is Takumi Katsuragi friendlier and has a personality more like Sento? This is because the Skywalls never happened. Katsuragi was more confrontational and abrasive because of his fight against Evolt as well as working for Faust. But in the Zi-O timeline, the Skywall never happened, he never joined Faust and his father never faked his death, thus he lacks the tragic backstory the World of Build Katsuragi has. As a result his personality developed a lot differently.
In episode 3, Hiiro for some reason gave Emu's note to Geiz instead of Sougo, despite it was Sougo and Tsukuyomi who asked about Emu. The reason to this is not outright mentioned, with Hiiro even being unsure why did he do that in the first place, but remember that both Hiiro and Geiz shares a huge similarity: They're both secondary riders who appeared very early and initially dislike the main rider, but becomes an ally anyway to pay close attention to the main rider.
Not only that, the note was written in German and Geiz has a German name. So he assumed that Geiz probably knows how to read it and gave the note to him.
It was revealed in Episode 4 the actual reason was that Geiz went to the past to warn Emu and Hiiro about Another Ex-Aid's coming. Since Hiiro had only met Geiz and not Sougo, he felt it more trustworthy to give the note to him.
Unlike Emu, Another Ex-Aid was forced to use a continue.
Another Ex-Aid is different from the other Another Riders because his belt doesn't match Kamen Rider Ex-Aid's Gamer Driver. This makes sense when you remember Ex-Aid is a composite Kaijin. Another Ex-Aid isn't wearing the Gamer Driver because he's wearing the Para-DX Buckle!
In Episode 5, it was revealed that Another Riders steal not just the history of the Riders of their series, but also their villains, as shown with the Scorpion Zodiarts vanishing. This explains why the Another Riders look monstrous; they're a combination of both the hero and their respective monster!
Another Build looks as if he were covered in scrap metal like the robotic Smash. Just how like humans who are willing to become Smash use Smash Bottles to transform, Another Build's Fullbottles are the same kind. Furthermore, what sets apart Another Build from the rest of his kin is that he is brainwashed into a wild monster, just like how the early Smash from Kamen Rider Build are unwilling victims of Faust.
Another Ex-Aid not only resembles Ex-Aid, but also a twisted version of Mighty from Mighty Action X, fitting with the Bugsters being video game bosses come to life.
Another Fourze resembles the design of the Zodiarts with orange and red trails along his body, and his transformation into Another Faiz is reminiscent of the ability for some users to evolve into Horoscopes, most specifically the Cancer Zodiarts' evolution after he was defeated as the Pegasus Zodiarts.
Another Faiz clearly has Orphnoch designs in his armor, with the rib cage on the chest piece and a mouth on the face plate, along with the placing of the "fins" on his head giving him a resemblance to a shark.
Another Wizard's features resemble a European dragon, Haruto's Phantom. Basically an idea of what WizarDragon would look like if he drove Haruto to despair. There's even a short shoulder mantle reminiscent of the White Wizard suit.
Besides resembling an animalistic human chimera like the Greeed, Another OOO incorporates elements from each of the Greeed its animals are based on, with Ā̃ṅkhs green eyes, exposed mouth, and white fur collar, Kazaris silver spots on black leather and claws, and Uvas green leg armor. Furthermore, what happens to wounded Greeed and Yummies? They bleed Cell Medals, just like Another OOO.
Alternatively, it also gives us the idea of how a TaToBa Combo version of a complete Greeed would turn out to be.
Another Double's design brings to mind the Nasca Dopant, and the belt has an Egyptian bird design - while not based on a particular Dopant, the latter element would fit right in with the Dopants in the Sonozaki family's theme of ancient-related Gaia Memories, seeing as how the right half of Double is part of said family.
The bird can also bring to mind the Xtreme Memory.
Another Den-O has Western demonic elements, most notably the horns replacing the eyes, somewhat contrasting with Momotaros, who is based around Oni (Eastern demons).
Another Gaim has tree roots growing out of him, bringing to mind both the Helheim Forest and the vines resulting from humans transformed into Inves. His weaponry is a zanbatō, just like the Overlord Roshuo used.
Another Kuuga is more animalistic than the Gurongi, who themselves had more animalistic forms than regular humans, not to mention being vastly larger than the Gurongi are.
Another Ghost's chest has a large eye similar to that of the Gamma's buckles along with eyes and horns similar to that of the Gamma Superiors. His nature is a more grim version to how Gamma are created, as Makimura's lifeless body is taken over to create Another Ghost, much like how Gamma gain their forms by possessing inanimate objects.
Another Ryūga resembles the humanoid Mirror Monsters with his animalistic dragon armor and Ryūga's weapons being naturally part of him bring to mind the Contract Monsters whose body parts made up the weapons summoned by their users. He's also based on Shinji's Mirror World counterpart, making his status as a Mirror Monster a bit closer than just in appearance.
Another Kikai seemingly defies this like the other future Riders, being a wooden creature instead of a machine, but that is part of the point; if Another Kikai was a machine then it would just be Kikai. But its resemblance to the Humanoise monsters is more subtle; it's an out-of-control monster that destroys humans, making it esoterically similar to the Humanoise machines.
Since Kikai and Another Kikai are made from Sougo's imagination, then the symbolism is two-fold; Another Kikai and the Humanoise are made from the same idea: Sougo being alone as a child. They both persecute and attack people spontaneously and without mercy, likely a twisted memory of how Sougo saw his own isolated childhood. This, in turn, means that Another Kikai shares aspects with the Humanoise on a more fundamental level than previously thought.
Another Zi-O is confusing when you consider how Zi-O is an anniversary show and he has no minions or original monsters to face, but then take a look at his faceplate. It's a skinned human face. Because Zi-O fights evil time traveling humans.
Another Blade (♠) wears nailed metal spikes and plates as armor on leather much like the Undead, and her knight motif resembles the Caucasus Undead.
The Lords were unique monsters who chose only to target those with the potential to become Αgitω. The Another Αgitωs spread their presence to other humans like a virus, essentially targeting anyone with the potential to fight like them.
Another Hibikis appearance resembles the Makamou parents, with his wild black main, demon mask, and exposed toes.
Another Kiva wears stained glass designs like the Fangire, and her roaring face resembles the reborn Bat Fangire.
Another Kabuto bears many features similar to the Worms, with insect carapace for armor, bones formed through his body, and a head resembling the Native Worms.
Related to the above Fridge Brilliance, the fact that Another Riders also steal the history of the villains also means theres little chance of the future becoming a nightmarish Bad Future because the villains won. So no Evolt destroying Earth, no Bugsters killing off players in a hopeless world wide MMORPG, no devastated Amanogawa High, no Smart Brain, and so on.
Makes sense when you realise most Riders are Phlebotinum Rebels, meaning to erase a Rider from existence is to erase the very phlebotinum that created both the Rider and villains, causing the villains to cease to exist as well.
The connection between Fourze and Faiz:
After being beaten, Another Fourze turns back into Another Faiz. Of course he does. Because after Four(ze) comes Five(Faiz/555).
And who ends up with Faiz's Ridewatch? Geiz.
This can also fit into the school theme as both Fourze and Faiz had big connections to the antagonists of their seasons (Ryūsei School was the location of the first major Orphnoch attack and was run under a former Smart Brain member, while Amanogawa High School was run by Mitsuaki Gamou in an effort to find Horoscope monsters).
Why combine the 555 and Fourze tribute arcs? Recall what the "World of Faiz" arc in Decade was - a high school arc. It's not a stretch to imagine we might see other tribute arcs combined in a similar matter.
Also, both Fourze and Faiz are essentially saying "Four-Z" and Five-Z". As in counting up.
Still in episode 5, Sougo makes himself fall off the stairs so that Geiz and Tsukuyomi can make the school nurse go away, allowing them to check up on her computer. Of course Sougo can think up this plan, he's a student, unlike Geiz and Tsukuyomi. So naturally, he knows the school would have a computer that keeps the data of all the students, in the nurse office.
Part of the reason why Geiz's name was spelled as such could be because the term "Gate/Gates" was already used in Kamen Rider Wizard. "Gates" here is a term referring to humans with potential magic.
Its fitting that Hayase, Another Wizard, only truly becomes a monster after he goes over the Despair Event Horizon (learning that his crush is already engaged and the theater he wanted to keep going for her is being closed down anyways). Just like a Gate turning into an evil Phantom when what little hope they had is crushed.
Why is episode 7.5 about the actors lamenting over having their efforts wasted on shooting scenes that went unaired? When you think about it, it overlaps with how Hayase/Another Wizard had wasted 6 years of his life and efforts trying to impress his crush by keeping her late father's theater running, only for it all to have gone for naught when he learns she had planned to close it to begin with.
Another Build was strangely easy to defeat compared to later Another Riders. While the riders introduced later are competent enough to run plans over a period of years and use the powers of their namesakes in creative ways, Another Build seems almost animalistic in his actions and cant seem to think of anything more complex than manifesting sports equipment despite having access to Builds wide array of powers. Then you realize that the Another Riders are specifically designed to oppose the main personality traits of their namesakes and have an overpowering obsession with their human forms strongest desires, albeit in twisted form. Sento is a genius who built his powers to make maximum use of his knowledge. The nameless basketball player had no real goal beyond survival and continuing his career. The opposite of a genius with only sports to hold onto results in a monster that personifies Dumb Jock and Jerk Jock: the furthest thing in the world from someone qualified to use powers based on the scientific process and creation. No wonder he was just the Starter Villain: he was the worst possible pick for his rider powers.
How come Another Fourze and Another Wizard can use the powers of their namesake Riders without having to collect Astroswitches or Wizard Rings? Because Fourze and Wizard's gimmicks were objects that granted weapons or powers unlike Fullbottles, which only provided powers while the weapons had to be built by Sento himself.
The Time Jackers' claim to have a plan to rewrite their future to their designs, but their methods dont seem to have a clear strategy behind them. They make random people Another Riders, then leave their new creations to their own devices without a bit of guidance. Then Another Faiz showed that the knockoff powers the Another Riders have arent just addictive, but they will eventually fade out on their own. At which point, the Jacker will approach the victim again and offer them another hit. Thats why they dont bother to simply brainwash or directly command their creations: the Jackers give the victim a taste, let them get in over their heads, then time travel to the point where the victim is desperate for more and offer one... for a price. Not only do they remove any threats to their plans by removing both Riders and monster, but they ensure that the new creature they make is a junkie they can influence whenever they are at their weakest.
Relatedly, the Time Jackers tendency to leave their Another Riders to their own devices is probably a strategy to test them. The Jackers want to create a Demon King puppet. That requires a candidate who is skilled, ambitious, and ruthless enough to want the position, but still vulnerable to their manipulation. That is a very specific sort of person. The Jackers run their schemes so that they can monitor their creations over the years to see if any of them fit the bill. They have more than 50 years for each potential candidate to develop, so it makes sense that they would keep a light touch and monitor them through time. The only reason they deviate from the plan is because Zi-O and Geiz present the only faction that can derail this scheme before they can find the right candidate. As long as those two are around, its impossible to even monitor the Another Riders after 2019, which forces them to resort to essentially guessing who the best candidate could be.
If so, why does the Anotherwatch transform into a different Rider when logically, the Anotherwatch should create the same Another Rider as the first time? Its possible that the Time Jackers specifically pick which Rider their victim will become but its also possible that theyre trying to give their candidate as many Rider powers as possible so that they can become more like another Ōma Zi-O, a Kamen Rider who has mastered the powers of the Heisei Riders.
Takumi is still alive, because since he didn't become Faiz, he was never an Orphnoch and his body didn't break down. As the result, he continued to live. It's either that or the time alterations or paradoxes are keeping him alive as explained in D-Video Special: Kamen Rider 4.
Kusaka is still alive, because his death at the hands of Kiba never happened. His personality change came because the event that caused his hatred of Orphnochs never happened which made him become a slightly better person in comparison to how he was in Kamen Rider 555 since he was not engulfed by his hatred and jealousy.
Zi-O started in 2018 and will end in 2019. As of 2019, Zi-O himself is a past Rider. To emphasize this point, the first episode to air in 2019 after the new year break is all about riders from the (alternate) future, such as Shinobi and Woz.
The reason Another OOO looks the most like the Rider it's based on? Because the person using that power IS ANOTHER KAMEN RIDER!
That and Kuroto Dan actually has a personality that matches the original OOO, who was a evil king consumed with greed and desire, along with the willpower needed to wield a Riders powers. His monstrous traits as Another OOO is likely because he doesnt have the heart of a Kamen Rider, a human heart that refuses to become a monster, especially since Poppy no longer exists.
King seems to be a downgrade from God, right? Well, since Bugsters no longer exist, Kuroto Dan was no longer present to their creation, which led him to believe he created new life. Without that, Kuroto Dan had no reason to believe he was God and therefore, went for the next best title his pride would allow him.
Not to Kuroto Dan it seems, it was implied he thinks of it as an upgrade instead when he first became Another OOO, claiming that the power of a King flowing through him surpassed the level of gods.
Technically, he isn't wrong. In Classical Mythology, the Titans were once rulers of the universe until the gods overthrew them. In Dan's twisted mind, beating the gods as a king is his way of surpassing the old rulers.
Given how easily Zi-O beats Geiz in Episode 9, Sougo's previous interactions with his classmates seems less "Sougo is not capable" to more "Sougo doesn't have the drive to do it".
What's interesting is that Sougo uses his Build Armor which is just saying that he's Obfuscating Stupidity.
The first episode establishes one of Sougo's longtime friends as a judo practitioner who'll put Sougo flat on the mat just to drive home a point. How many times has Sougo taken away the technique and not the lesson?
After seeing such a brutal display of skill and power from Zi-O, all the previous battles he had are now put into serious questions.
First off, how could Sougo know how a Kamen Rider fights if basically all the past riders don't remember a thing about their old lives? The only person he could turn to was Geiz, but Geiz wasn't going to give him information out of fear he might give Sougo the means to become Ōma Zi-O. Hence, Sougo took another route. He worked with Geiz and Tsukuyomi and tried the best he could to fight the Another Riders all the while quietly observing Geiz's own abilities and the Rider Armors. By the time Episode 9 came, Zi-O had worked out all the strengths and weaknesses Geiz had and even if Geiz used the Rider Armors, Sougo have some countermeasures prepared for them.
Secondly, Sougo had the Time Mazine which he can use to travel back in time and watched all the battles the Past Riders had fought in to get the lessons he needed. However, this part comes with Nightmare Fuel - it might also unknowingly be the reason why Ōma Zi-O is so powerful.
While at first glance the OOO TaJaDol Combo Ridewatch seems like it was designed for toy sales and/or promotions, there is a technical in-universe reason for it existing, beyond simply Eiji remembering Ā̃ṅkh. In the final battle of Kamen Rider OOO, Eiji used the Core Medal housing Ā̃ṅkhs consciousness, and he announced the names of TaJaDols Core Medals of the transformation. Because of this, it's not too farfetched to say that, in that moment, Ā̃ṅkh was Kamen Rider OOO (albeit as the Transformation Trinket), alongside Eiji, as Ā̃ṅkh briefly did fight with Eiji afterwards. Naturally, with Ā̃ṅkh erased from history, since Eiji was also part of OOO for this, it's not a stretch that both Ridewatches would end up with him, due to his shared ownership of this 'Kamen Rider Ā̃ṅkh-OOO'.
One thing I observed in Kamen Rider Zi-O is that there is this theme of not everything is black and white but mostly grey.
Coincidentally, Sougo's Zi-O base form is grey which correlates with his personality. Sougo has a white face that shows he wants to be an overlord that will be loved and respected by everyone but has some shades of black where he isn't above using manipulation and brute force to achieve his goals.
Grey could also refers to the Kamen Riders and the Another Riders as a whole. Kamen Riders were forcibly created by monsters to destroy humanity but chose to use their powers for good and become heroes. Another Riders are people that chose to become monsters with the best of intentions but their powers soon corrupt them into become a threat to humanity.
This might be obvious, but the reason the Another Rider remove the monsters and additional riders from history is because they aren't just removing the Kamen Riders' history - they're removing the Kamen Rider series, as a whole.
This is actually implied by Sento in Episode 2.5 when he said that it's like "Kamen Rider Build" as a series does not exist, but at that time no one, not even the viewers, realized what he's saying is literal.
In Kamen Rider Heisei Generations FOREVER, the ultimate plan of the Big Bad is to erase the entire Kamen Rider franchise. Part of that plan was for him to become Another Kuuga. Without Kuuga to open the way to a new era of Kamen Riders, the Kamen Rider franchise would have never been restarted.
While Sougo bungles up the Finishing Moves of the past Riders, they are close to how the originals were when you seriously think about it.
Build Armor: Ignoring the pathetic attempt at the theory blocks, Zi-O's attack is similar to Build's RabbitTank's Vortech Finish by sliding down a graph line, if your replace "attack with kick" with "attack with drill".
Ex-Aid Armor: While it almost seems like a subversion, the way Zi-O knocked his opponent into the air by ground pounding with his Gashacon Breaker Breakers is similar to Maximum Gamer's Maximum Critical Break where Ex-Aid pounds the ground with enough force to knock his opponent into the air.
Fourze Armor: With Zi-O transforming into a rocket, and performing a corkscrew kick, he's basically performing an altered version of the Rider Rocket Drill Kick if you take away the Drill Module.
OOO Armor: The three medals facing in front of him are a nod to how every finishing move OOO performs has three circles in front of him. Plus, besides the aforementioned medals, the attack is close to the original TaToBa Combo's finisher.
Gaim Armor: It's a reverse of the very first finisher Gaim performed in his debut fight where Kouta trapped the Byakko Inves in an energy orange before slashing him.
Double Armor: Oddly enough, it's a near copy of the Triple Extreme attack as Decade, Shotaro, and Philip are replaced by Zi-O and his two Memory Droids.
This goes into Fridge Heartwarming. The flow of the arcs so far have strongly indicated that the flow of time tries to resist changes like the ones the Time Jackers are making, and because of that the Riders and the people close to them still gravitate together even though the stories that originally brought them together don't exist anymore. That includes the Another Riders, which is why nearly every original Rider has been found by hanging out near the Another Rider's stomping grounds. In the case of people who outright can't exist in the new timeline anymore like Ā̃ṅkh, Eiji still wears a memento of him even though he has no reason to do that in the broken timeline. Time wants to go back to the way it was, much like how in Den-O the memories of people in the future would eventually correct any damage done to the past unless the damage was so severe that there was nobody left to remember what was supposed to have happened.
Since Kamen Rider Decade was the 10th anniversary Heisei series, why combine its tribute arc with Ghost? Wouldn't it make more sense to combine it with Blade (♠) or Gaim (5th and 15th anniversaries respectivelynote if going by the show's number)? Technically speaking, Ghost is an anniversary show in the same way Αgitω, Kabuto, and OOO are - if you go by what year it aired in, as opposed to what number series it is, Ghost is the 45th anniversary shownote 45 years since the original Kamen Rider aired (with Αgitω, Kabuto, and OOO being the 30th, 35th, and 40th anniversary shows respectively).
With the interference of Future!Sougo changing the events in the current timeline, he now effectively becomes an alternate-future Sougo, due to how Present!Sougo received the Gaim Ridewatch differently and first activated it in a rather different situation from Future!Sougo.
It makes sense that Another Faiz's powers faded away after years of use since the rider he's based on also loses his power eventually, because their Transformation Trinkets deplete Orphnoch DNA and will eventually kill the user which was especially shown with the users of the SB-913B Kaixa Driver who usually die after a few uses.
The Time Jackers method of offering deals to their Another Rider candidates seems very odd. The cases of Another Ghost and Another Build show that they dont have to bother playing along and can just force the victim to transform. So why bother with the formality? Because in the cases where they power was forced on a victim, the resulting Another Rider suffered severe mental degredation and was only useful as a regular monster. The Jackers want a Demon King that they can control, not some deranged beast. Theyre looking for those who will crave power when offered. Especially those who use it to take their desires at the expense of others while retaining enough of their human intelligence to do so properly. Its because those are the people most likely to have the ambition and drive to become the Demon King.
When one thinks about it, Another Ghost was collecting his series gimmick much like Another Build was collecting Fullbottles. Ghosts gimmick were the Eyecons, souls of great men and women throughout history. Another Ghost steals the lives of troublemakers, normal people who wont be or are not yet great.
Why does the Decade Armor transform into the Grateful Damashī form rather than Ghosts first Mid-Season Upgrade, Tōkon Boost Damashī? It might be because due to the changes in the timeline cause by the appearance of Another Ghost led to Takerus fathers sacrifice to be undone and so, the Tōkon Boost Eyecon no longer exists. The fifteen real life, long dead luminaries who became the Eyecons used for the Grateful Damashī, however, wouldnt be erased from history and therefore, the power of the Grateful Damashī still exists.
Have to give the writers credits for conceptualising how Tsukasa doesn't need a Time Mazine to travel through time despite being a dimensional traveler: He just needs to go to a dimension where the past/future happens in his present time.
Why is Tsukasa an enemy? Because hero or not, he is STILL the Destroyer of Worlds whose presence causes non-AR Rider worlds to collapse into non-existence. For the new Rider's world to survive, they must do as the other Riders did: defeat Tsukasa, ending his threat to their world. His fighting them and defeating them is part of HIS side of this cycle: the Riders must remember him so he can come back to life to continue his journey.
Given that the Another Riders and Rider Armors are based on the same kind of technology, and that the Anotherwatches usurp the powers and history of the Kamen Rider it's based on, why are the Riders not restored when Sougo defeats the Another Riders? Simple: his Ridewatches, based on the same technology, are keeping the Riders erased by also usurping the Rider's power and history. All that changes is getting rid of the competition.
Why has Decade not lost his powers despite the existence of a Decade Ridewatch that should be usurping his history? Because Decade's history does not stand alone like the other Heisei Riders. Decade does not have an original power source or monsters. It's connected to the history of Kamen Rider Ichigō by way of the fact Tsukasa is an incarnation of the fuckin' Great Leader of Shocker, meaning his power is unique among Heisei Riders as it's connected to the original Kamen Rider. To erase his power, you need to erase Shocker itself, and that would only happen if Another Ichigō came into being.
Additionally, Decade is a Rider who isn't from the original mainstream timeline. The Time Jackers' temporal paradox only applies to their universe, not Riders from A.R. Worlds. Decade and co. have been jumping into dimensions and fight the Dai-Shocker army, who can also jump into various worlds.
Ever since Geiz returns to live in 9 5 DO in episode 12, he has been assaulting Sougo even after the youth just waking up from sleep. One has to remember that Geiz was Curb-Stomped by Zi-O in episode 9 when he himself is far better trained in combat, thus learning the hard way to not underestimating Sougo, even if he has just receiving his powers as Zi-O.
When using the Wizard Ridewatch, whats announced is Please! Wizard!. Almost as if the user of the Ridewatch is asking Haruto nicely if they can borrow his powers, just how Haruto asked WizarDragon for his magic.
In episode 16 Zi-O uses Ghost Grateful Damashī to summon a bunch of Parka Ghosts to snatch back the extra Zikū-Driver, and the one that actually gets it is Goemon. He's the Loveable Rogue so it was clearly intentional.
Given that historically he was a noble thief much like Robin Hood, you bet it was intentional.
It's no wonder that Ōma Zi-O is a Fashion-Victim Villain in his civilian clothes. Present time Sougo has no fashion sense either.
As of episode 22, the show has debuted Zi-O's Mid-Season Upgrade, Zi-O II. While at first this seems like a silly and lackluster name, it actually makes sense in the context of the show. Sougo is becoming a new king with that Ridewatch. The form isn't Zi-O #2, it's Zi-O the Second.
This also applies to Geiz Revive. In the new timeline, Geiz defeated Ōma Zi-O. He revived the future.
Why do the future riders use a modified Zikū-Driver as their belt buckle? The practical reason is because it's from the same show and Toei doesn't want to make a new unique belt for every future rider. In-universe, however? That's because those belt buckles are based on their savior's, which is Geiz's own Zikū-Driver.
Given how Kamen Riders are usually connected to the evil they fight in some way, it would be more likely some evil organization saw the potential power of the Zikū-Driver and tried to replicate it, only for it to fall in the hands of future Kamen Riders who would use the evil power for good.
Another explanation? The Future Riders use modified Zikū-Drivers because theyre creations of Sougos imagination and rather than coming with his own unique Drivers, Sougo simply adds some modifications to the only Driver he knows.
Turns out they were created by Sougos dreams and his time manipulation made them into reality, so they are connected to a future evil, Ōma Zi-O.
White Woz doesn't just change the future, he directs the future to go a certain way, little different from a movie director. This is further hinted by one of his motifs (Film), Futurings (which closely sounds like "featuring", a word seen commonly in movie posters), him being dressed very similarly to artists and directors, topping it off with the beret, and the very way his BeyonDriver announces.
Geiz is quick to agree with Sougo's idea to distinguish the two heralds as 'Black Woz' and 'White Woz' in #18. This might look odd given their complicated relationship, but the explanation is simple. Whatever annoys Woz is welcomed by Geiz.
The way White Woz can rewrite reality with his futuristic book makes more sense if you compare it to Black Woz's old fashioned book. White Woz's book is essentially a tablet for words that can be edited if there is a mistake that needs to be corrected while Black Woz's book is ink-printed and any mistake can't be undone once printed out.
In other words, White Woz can freely manipulate the current future that doesn't belong to his own future timeline while Black Woz can only give guidance and follow the events that has been set.
The real brilliance sets in when you look at what their books really are. Black Woz has a history textbook; rigid, unbending, and absolute. White Woz has a movie script; while certainly going in one direction, it is malleable and can change on a whim to suit the situation, but there has to be some plot justification, the same way White Woz can only cause things that already had a chance of happening.
The Time Mazines that the Time Jackers have come from shows that match that of their personalities.
Heure has Captain Ghost, from Kamen Rider Ghost. The show has a Slice of Life feel to it and has one of the more optimistic Riders in the franchise. What better inspiration for a carefree kid to follow?
Ora has Castle Doran, from Kamen Rider Kiva. Considering the tragedies that go on in that series, it makes sense for a woman focused on invoking tragedies to manipulate people into becoming Another Riders.
Kamen Rider Geiz is nearly entirely red despite being the second rider and being more in line with an Anti-Hero. But then it's revealed a potential future has him beating Ōma Zi-O and being considered the savior.
Why the change from Another Riders based off primary Past Riders to Future Riders (Shinobi, Quiz, Kikai) or minor Riders (Ryūga)? Note that this change to Riders other than the primary Riders of each year happened right after Sougo obtained the Decade Ridewatch. Its entirely possible that using the Decade Ridewatch, which gives the user the power of all nineteen Heisei Riders, allows Sougo to defeat the main Rider without having to obtain their Ridewatch. All he would have to do is set the Ride HeiSaber to whatever Rider hes fighting and finish them off. This method, however, doesnt work on Another Riders who arent main Heisei Riders, like the Future Riders or Ryūga.
The Watsonian reason that Another Ryūga is used instead of Ryūki? Because Ryūga is already the Evil Twin of Ryūki. In the same way that Another Αgitω is already the Evil Twin of the normal Αgitω, Ryūga is an already existing template of what an inverted Ryūki would look like. Not to mention, Another Ryūga is made from Dark Shinji, who is already an inversion of the real Shinji by nature.
In a way, Zi-O did beat Another Ryūga with the same power he uses, but unlike the normal Ridewatch-obtaining process, Sougo obtains the other half of the Zi-O II Ridewatch from his mirror counterpart. So basically Ryūga was not defeated with his own power, but a power which had the same property of his origin (the Mirror World).
Kamen Rider Woz's Futuring forms changing his "strap" design instead of giving him Armor is likely in line with how a number of smartwatches feature customisable straps.
In theory, White Woz and Black Woz represent the bad sides of the ones who oppose each Rider's future. White Woz is a smug Knight Templarwho can influence the future, matching Ōma Zi-O's arrogance and control over time. Black Woz is pragmatic The Chessmaster, mirroring Geiz's very direct approach with Tsukuyomi's educative approach of trying to convince Sougo to change his future by his own choice by simply telling him how bad it's going to be if he doesn't change.
It's fitting for Zi-O to use the Double Ridewatch against Kamen Rider Woz, as he is asking White Woz to count up the sins he committed in his pursuit of creating Miridewatches.
There are three Ridewatches for the three main characters Rider forms, and only two are in Japanese script, Sougo's and Geiz's, and the third is in English, Tsukuyomi's. At least until you realize Tsukuyomi's isn't in English, it's in rōmanji!
The three main riders represents the quality of Sānxīng and the Three Jewels of Buddhism.
Zi-O is the Buddha, related to his ascension to Ōma Zi-O and the Shòu to his longevity being a tyrant 50 years in the future.
Geiz is the Dharma, relating to his victory as Geiz Revive over Ōma Zi-O and the Lù to his status as the future savior in the alternate future timeline.
Woz is the Saṃgha, relating to him hailing Geiz as his saviour and the Zikū-Driver acted as a base for the Future Riders and the Fú to the supposed prosperity after the defeat of Ōma Zi-O.
For Abrahamic religions, the three main riders represents the Holy Trinity (in Christianity), the three branches of Islam and the Three Patriarchs (in Judaism).
For Indian religions, the three main riders represents the Trimūrti, the three pillars of Sikhism and the Ratnatraya.
It is fitting that Zi-O II would have an Artoria-styled finisher. After all, he is now the Once (past) and Future King.
Why weren't Sougo's attacks reflected once he became Zi-O II? Because by that point, Sougo accepted his mirror self and therefore, his mirror self is now on his side and wouldn't attack Sougo.
At first it seems Tsukuyomi's decision to kill Sougo seems sudden at the end of episode 22 but considering how she stated she believes that Sougo could never become Ōma Zi-O at the start of the episode, it makes sense. Tsukuyomi having seen how kind present Sougo is like Geiz couldn't mentally connect Ōma Zi-O with the current Sougo, thinking of them as completely different people. Even thinking it was impossible for Sougo to become the Evil Overlord that she knew. But seeing Sougo using powers that Ōma Zi-O has finally let her realize that Sougo truly does have the potential to become Ōma Zi-O, deeply scaring her.
Kamen Rider Decade gave its main riders subtractive color themes (magenta for Decade, cyan for DiEnd, and gold instead of yellow for Kuuga). Zi-O does the same for the riders' visors, with Zi-O having magenta, Geiz having yellow, and Woz having cyan. This is most obvious with Zi-O Trinity, which unites the power of all three riders.
Mirror Sougo can be represented as Sougo's deepest fear of him turning into Ōma Zi-O due to the former constantly mocking the latter about his future destiny.
The female Humanoise posing as a candy shop owner was smart: Robots like them don't eat, thus anyone who comes in to buy a candy from her is most likely a human that needs to be eliminated.
At first, Geiz's super form being based on an hourglass seem weird, until you realize it represents the moral dilemma Geiz faces on how to prevent Ōma Zi-O's future.
The blue colored Geiz Revive Shippū represents the "kill Sougo" decision. It is a speed based form representing this decision being the quicker way to deal with the problem. It having a lower defense stat represents how easy it can be for Geiz to lose himself and his morals if he goes down this path.
The orange colored Geiz Revive Gōretsu represents the "befriend and guide Sougo" decision. It is strength based, representing the strength Geiz needs to resist the temptation of the other path. Its lower speed stat represents this decision being the slower of the two.
How come Another Zi-Os date is 2019 rather than Zi-Os actual year of origin, 2018? Because 2019 is the year Zi-O truly starts to gain his own powers separate from the Ridewatches of past riders, in the form of the Zi-O II Ridewatch, which also explains why Another Zi-O has Combat Clairvoyance.
Given that the Geiz Revive Ridewatch was made from the original three Miridewatches, it would make sense that the Revive form had some homages to the three Future Riders.
Revive Gōretsu is the strongest of the two forms, and has a higher punching stat. Kamen Rider Kikai was a Humanoise/Robot themed Kamen Rider that had primary focus on powerful punches.
Revive Shippū is the fastest of the two forms. Kamen Rider Shinobi was a ninja themed Kamen Rider, and used speed to his advantage against his foes.
Finally, both Revive forms share the color scheme of Kamen Rider Quiz (red/orange for Gōretsu, and blue for Shippū). Also since Geiz Revive Ridewatch allows for instant form change, it can easily confuse enemies fitting the Quiz's Confusion Fu fighting style.
Geiz Revive can beat Zi-O II despite Zi-O II's massive power due to:
Revive Shippū is so fast that Zi-O II's Combat Clairvoyance means nothing if Sougo can't react in time to even use the power.
And if Sougo does grab Revive Shippū to stop his speed, Geiz can just change to Revive Gōretsu whose strength means the close distance is now to Geiz's advantage.
Finally Geiz can switch between the forms instantaneously meaning Sougo can't correctly react.
In the series, there are two characters who seemed to share the Guardian mold, which are Kamen Rider Kikai and Kasshin, the latter being Ōma Zi-O's servant. As we explored that Kikai is a product of Sougo's childhood toy robot given life from his growing power as Ōma Zi-O, one can argue that Kasshin would have Kikai's analogue in Ōma Zi-O's timeline.
A very interesting tidbit that can be noted with the names of the Time Jackers, a very interesting piece of Fridge Brilliance comes in once you realize their names in the order that they were introduced; Heure, Ora, Swartz, and Tid. They spell out HOST, something that they are constantly looking for in the series events.
The reveal that blank Ridewatches can steal a rider's powers explains how Ōma Zi-O was able to steal the Heisei's riders powers since they were unlikely to just give them to him like our Sougo.
After being revealed as the one who instilled the desire to become king into Sougo, Swartz forcing his candidates to become Another Riders makes more sense. Hes already got his perfect candidate for becoming Ōma Zi-O so why bother searching for another candidate? Turning people into Another Riders is likely just to keep the other Time Jackers from getting suspicious and to keep the timeline going the way he believes it should.
Also by creating weaker Another Riders, he's forces Sougo to gather the Heisei Rider powers as he wants while making it harder for Sougo to lose.
Back in Episode 16, even though Ōma Zi-O was erased from existence, the Dai Mazines and Kasshin still existed, and Swartz was even able to reprogram the Kasshin in the present to assassinate Geiz and Sougo. With the revelations of #27, it makes sense: The Dai Mazines and Kasshin were never made by Ōma Zi-O, they were made by Swartz, who would know how to control them better than anyone.
Kaito's debut in Zi-O's Blade (♠) arc, come as a very huge moment of fridge: not only does it neatly tie in with Tsukasa's cameo in the previous two episodes, but also remember his debut in the original Decade series; he first made his cameo in the World of Blade (♠), at the end of the second part, and the fact that the World of DiEnd is based off the events of Kamen Rider Blade Missing Ace.
A lot of Tsukuyomi's actions from episodes 23 to 27 make a lot more sense if you remember her initial attempt to prevent Ōma Zi-O from rising. She tried to stop Sougo from even becoming Zi-O, thinking he was doomed to become Ōma Zi-O if he gained that power. This shows she's something of a fatalist and thus moment Sougo gained Zi-O II's powers which are the same powers as Ōma Zi-O, she resigns herself that he's destined to become the tyrant she knows.
Episode 32 also reveals she thinks Time Power is inherently corruptive in Episode 32 which further explains her mindset.
Geiz not being able to handle Geiz Revive's power makes sense as unlike Sougo and Zi-O II which is a natural extension of his time powers, the Geiz Revive Ridewatch came from Shinobi, Quiz and Kikai's powers. Geiz simply can't handle the power that far exceeds his own powers.
The reason the Zi-O Trinity Ridewatch was created through White Woz and not Black Woz? Simple, White Woz was the original wielder of Kamen Rider Woz so it makes sense the Ridewatch is created from him, Zi-O II and Geiz Revive Ridewatch.
During Zi-O's fight against Another Blade (♠), the former has a hard time fighting due to the latter having thick armor akin to Blade King Form (♠), it is necessary for Zi-O to use Gaim Armor to have an equal ground to fight Another Blade (♠).
The three riders fighting Woz in #29 (DiEnd and his two summons, Baron and Knight) all relate to Zi-O somehow. DiEnd is from Decade, the previous anniversary season. Knight and Baron are from Ryūki and Gaim respectively, two chaotic battle royale-esque series. Even better, they are Geiz's foils. Ren needs to kill Kido to advance in the Rider war, whereas Geiz needs to kill Sougo to save the future. Both are stopped and forced into situation where they start to like their adversaries. Kaito is a negative reflection of both, showing all of Ren's bad qualities and everything that Geiz doesn't want to be as apparent by their meeting in the Gaim arc of Zi-O.
And as for Kamen Riders Accel and Birth? Well, they made their proper fighting debut in the next years and their Rider belts are contrasts to the titular Riders. Birth and Accel just need one collectible to transform, whereas their title Riders need two and three sets altogether to complete a single form.
The reveal that the Future Riders are from Sougo's subconscious power to manipulate the future hints at how all three were created from some fear Sougo is hiding.
Kikai is the most obvious being Sougo's toy brought back to life. Kikai's story has him turning against his kid friends and they nearly give up hope that their friend was a good person. But Sougo is able to reconcile their friendship which shows Sougo's desire to reconcile with Geiz and Tsukiyomi who at the time of the Kikai arc didn't trust Sougo.
In the Shinobi arc, Renataro wants to do good but is scared that he'll never grow strong enough to protect the weak thus he clings to the powers of Another Shinobi in fear. Sougo told 2019!Rentaro to trust his future self, words that Sougo would repeat to Dark Sougo in the Ryūki arc. Showing that Shinobi was the result of Sougo's fear of his possible future as Ōma Zi-O but desire to believe that he'll become a better person.
Mondo's quest in the Quiz arc was to find out if his father truly loved his mother and thus by extension himself. We have since learned that Sougo only started to desire to be king after his parents were killed. Sougo might wonder if his parents could love him if they knew he would grow up to be Ōma Zi-O but desires that they would just as Mondo found out his father truly does love his mother.
Ginga also factors into this, if one assumes he was also created by Sougo's timeline powers. He's a villainous ruler with astonishing power who comes out of nowhere to ruin people's lives. Sound familiar? He's how Sougo sees Ōma Zi-O, his own future self. His fears of what he could become ended up creating a creature that is almost exactly like Ōma Zi-O. They have multiple similar traits in their Rider costumes, which is likely not a coincidence. Hell, Ginga even has a Badass Baritone similar to Ōma Zi-O's.
DiEnd uses a Dimensional Wall from Decade to reveal the person he's been working with, Ōma Zi-O, who exists in the future instead of an alternate reality. This is not without precedent; the shimmery wall was all that was needed to go from the World of Black RX to the World of Black, which was really the year before.
The reason why most of the early Heisei Riders are in modern times as opposed to their respective years like the other, later Heisei Riders is pretty simple: the Decade-Build Riders don't look like they've aged one bit, whereas the earlier Heisei Riders have. Rather than attempt a Fake Shemp when the Riders go back to the past to better resemble their original versions, they decided to emphasise on the fact that they're Older and Wiser by setting them in modern times.
Word of God states that due to the piling time paradoxes, Another Riders no longer steal the histories of their respective Riders. Another explanation for why Riders and their Another Rider counterparts can now co-exist can be that Sougos growing power over time is allowing him to subconsciously stop the Anotherwatches from erasing a Riders history.
When one thinks about it, the three Future Riders Shinobi, Quiz, and Kikai each symbolize a part of what it means to be a Kamen Rider.
Shinobi- A Kamen Rider is usually the product of evil forces but thanks to their Heroic Willpower, they can overcome their evil natures and become true heroes. Kamen Riders also rarely, if ever, get thanked for their heroics but that doesnt stop them from continuing to fight evil in the shadows.
Quiz- A Kamen Rider sometimes has to deal with hard choices but they will always pick the right answer, the answer being to save the world.
Kikai- Above all, a Kamen Rider is a protector of children and will do anything to protect their smiles.
Ginga- A slight inversion, as he represents Dark Riders rather than heroic Riders.
The purpose of the restarted Rider War in Zi-O is different from the Rider War in Ryūki:
First, the restarted Rider War isn't about a battle royale to the death over a single wish but instead a battle to find the right person to defeat Another Ryūki.
Secondly, the organizer of this Rider War is Sara which is dying from her illness and wanted to prevent the death of innocent people for her sake; which is starkly contrast to Shirō Kanzaki that organize the previous Rider War which has been manipulating and killing people for the sake of saving the life of his sister, Yui.
The absence of Ryūki and Knight Survive Form and the Badass Decay of Óðinn have a good logical explanation if one think about it:
Sara doesn't really know how the Mirror World and the Rider System work like Shirō Kanzaki did. Meaning she doesn't have a method of accessing the Survive Cards and granting them to the Riders.
The last scene of Rider Time: Kamen Rider Ryūki has the Dragreder and Darkwing Advent Cards disintegrating when Shinji tosses them in the air. Given how Ridewatches usually work, of course they would disappear. They're not really supposed to be there since there's already Ryūki and Knight Ridewatches.
Tsukuyomi not knowing who Oda Nobunaga is but Geiz does makes much more sense when you realize she has amnesia. She probably forgot it and was never retaught it since as part of the Resistance, history isn't that important.
In the previous tribute arcs, the secondary rider usually did at least decent against the Another Rider if they fought said rider, but come the Αgitω Arc, Another Αgitω tears through multiple Kamen Rider G3s with little difficulty. It might seem odd at first until you remember that the G3 system fared poorly against the Lords in its home series. It wasn't until Makoto Hikawa switched over to the G3-X that he had more success against the Lords; up until that point, the majority of victories against the Lords were by either Shouichi or Ryou (Gills).
Also adding to that it wasn't Makoto in the suit. So not only are the G3 too weak but they don't have any experience fighting anything like the Another Αgitωs.
Furthermore, G3 is based on Kamen Rider Kuuga, and by the logic of the show wouldn't be able to defeat something based on Αgitω.
It makes sense that one of the only beings capable of beating a opponent with immense power over time like Zi-O is a master over the powers of space like Ginga.
What are the final Ridewatches (as of the Hibiki arc) that are to be collected? Kiva, Kabuto, and Den-O, three of the four Phase 1 Heisei Riders who had plots involving Time Control and Time Travel.
Among them also includes Drive, which also involved Time Travel in its movies.
The statuettes on Zi-O's final form mirror Ōma Zi-O's Kamen Rider statues.
Yuko kept pretty good control over Another Kiva, and unlike many Another Riders kept control of the power, not going on a mindless rampage. Even her rampage at the end was exactly what she intended. Why? Because she was ALREADY a horror movie monster before becoming Another Kiva. She's an implacable-type serial killer with an extremely inefficient weapon (in this case manhole covers) who seldom accelerates above a walk.
She also is already crazy. The Anotherwatch did little more than inflate her already-impossible ego, still allowing her control of herself.
In the Kabuto arc, when they destroyed Another Kabuto the first time, it reveals KickHopper underneath. In other words, KickHopper is Casting Off his outer shell, just like the other riders in Kabuto.
Alternatively, the next episode shows that Yaguruma transforms into Another Kabuto from KickHopper in a manner resembling a twisted Cast Off. Transforming back into KickHopper to protect the Anotherwatch is like using Put On to return to the more heavily armored form.
The point of the Blade (♠) arc is for the Time Jackers to unleash a horde of Undead to invade the Earth and ending the world. In the next arc, Αgitω, they use Another Αgitω to spread itself like a virus. Two arcs later in Kabuto, meteors carrying Worms are falling on Earth. It seems like the Time Jackers really tried to stop Zi-O by overwhelming him with a horde of monsters.
Adding to that Heure and Ora are interested in gathering the Ridewatches now instead of just the Anotherwatches as seen in the Αgitω and Hibiki arcs. They know that Sougo is getting close to becoming Ōma Zi-O and they're interested in stopping his rise thus the change in tactics.
Kenji Matsuda not reprising his role as Kamen Rider Zanki makes sense given how Hibiki was not negated out of existence. Zanki's still dead.
At first I was confused by how in #39 the Grand Zi-O Ridewatch was made both without the Drive Ridewatch being formed, and why the Den-O Ridewatch wasn't assimilated into it, and instead was still in his hand. Then it hit me; To answer the first problem, the Drive Ridewatch that Geiz brought back was likely a decent substitute for Grand Zi-O. To answer the second one, the lights that went from the Ridewatches into Sougo's hand were likely not the Ridewatches themselves, but instead aspects of their power and Rider histories, to help craft Grand Zi-O's Ridewatch. The Ridewatches are likely still on the Ridewatch Daizer.
Adding onto this, the real reason Ōma Zi-O stated that Sougo would need to make his own Drive Ridewatch and complete the collection? The movie form answers it: Zi-O's Ōma Form. It's possible that in Ōma Zi-O's timeline, when he got all of the other Ridewatches he got both Grand Zi-O and Ōma Zi-O's Ridewatches at the same time, and fused the powers together into what we see in 2068. But Sougo only got Grand Zi-O due to not having an original Drive Ridewatch.
The troper think the above point is rendered moot as it is explicitly stated in Zi-O arc that Zi-O directly became Ōma Zi-O on the Day of Ōma without the creation of the Grand Zi-O Ridewatch as it didn't exist at all in Ōma Zi-O's timeline just like the creation of the Zi-O Trinity Ridewatch in the Blade (♠) arc.
When Ōma Zi-O said that the power of Grand Zi-O isn't a match for his power, this may be a case of Badass Boast for Ōma Zi-O but he actually pulls off a Villain Has a Point towards Sougo:
Notice that when Sougo is transforming into Grand Zi-O, he puts the Zi-O Ridewatch into the main slot instead of the Grand Zi-O Ridewatch, which heavily implies Sougo is subconsciously holding back his true power from being fully manifested.
To further support above point, look the position of the Ōma Zi-O Ridewatch in Ōma Zi-Os driver. Him putting the said Ridewatch into the main slot indicating he unleashing his true power without any kind of Restraining Bolt to him and compared to Sougo who is using Grand Zi-O like his regular transformations as an armor instead of using it as his main form.
This may be coming a bit late, but I was reviewing how Geiz Revive was killing Geiz when he initially used it, and how the weakness was removed. The producers said it was due to adapting to the power, but what if that wasn't the full reason? White Woz was aware that Geiz could die. Hell, he even expected it. It's possible that in the Revive timeline, Geiz did die, as a Heroic Sacrifice to stop Ōma Zi-O. And him continuously receiving damage was related to that. But when the Revive timeline was no longer guaranteed and Geiz stopped fighting Zi-O, Geiz wasn't fated to die anymore, therefore allowing him to adapt to Revive's power.
In the Blade (♠) arc, that occurred right after Geiz and Sougo fully became allies, the Zi-O Trinity Form was formed which gave Geiz a safe alternative to Geiz Revive. Thus he has more time out of the dangerous form which gives him time to adjust to its powers. In the Another Zi-O arc when Geiz first got Geiz Revive, he transformed into it five times in the span of two days, once against Sougo and Hiryu, once against just Hiryu, twice against Black Woz and once teaming up with Sougo against Hiryu. Makes sense his body reacted horribly to the power, not only did he just get it but he was borderline abusing the form.
The victims that became Another Riders. They were transformed from the year a Kamen Rider has first appeared but where were they and what they were doing? Another Build spent a year and he did a lot of damage. What happens if Another Rider has been around for 20 years like Another Kuuga?
Actually addressed with Another Fourze/Another Faiz. The heroes were able to find clues in the news from all over the time period of 15 years.
The basketball player in episode 1 was basically given a lose-lose situation. He was either going to be hit by a car which would either kill him or at least seriously injure him or he would end up being turned into a rampaging Kaijin Rider Another Build.
Also good thing that when the basketball player was truly rescued he wasn't sent back to being killed by the car and instead he gets to live.
Also if you think about it with how history changes work with Kamen Rider Den-O, those changes are probably small and insignificant, because those people aren't people whose life or death would cause a big change in history. They are just normal civilians unlike more important historic figures such as the Kamen Riders who are erased from history.
Or maybe the Riders all died of old age by the time Ōma Zi-O finally rose to power. Again, you must remember this is 50 years in the future and we barely know how long Ōma Zi-O has ruled the future or how he managed to do it. It's still too early to make the call.
Around the middle of the series it's spelled out that the Day of Ōma WILL happen in 2019. And there are no more Riders after Zi-O in that timeline, because he prevented any more from appearing. Plus, Flash Forward shots when Geiz talks about past riders shows their statues cracking to reveal the Rider inside, suggesting they've all be captured and turned to stone.
Look at the first five Ridewatches Geiz got - Ghost, Drive, Faiz, Genm and Wizard. Four of them cameBack from the Dead at least once, while the last one comes disturbingly close once, looking like he had a heart attack at the time. It doesn't look good for Geiz.
On the other hand, his Super Mode is called Geiz Revive.
Why couldn't Īda find a heart donor for two years? Aside from all the moral problems, there is one huge flaw in his plan: the organs from his victims would be infected with the virus he spreads, which means they cannot be donated. Therefore, Īda actually PREVENTED his son from having a chance to survive.
Geiz already having the Drive and Ghost Ridewatches. Doesn't seem like a horror until you remember that Anotherwatches and Ridewatches in essence steal the 'lives' of Kamen Riders, It means Geiz has already dealt with the Another Riders of Ghost and Drive, which means TAKERU COULD BE DEAD!
But on the other hand, "stealing the lives of Kamen Riders" seemingly extends to their backstories, so that part could be removed together with becoming Kamen Rider Ghost for his case.
On the other hand, this could mean that Gammaland is surely dead by now, which means Alain could be dead as well. Still dark.
And what about Shinnosuke? Geiz having his Ridewatch would mean Kamen Rider Drive no longer exists too.
But that also implies a lot of losses were averted and that Krim Steinbelt is alive and well.
A moot point in the end: he HADN'T dealt with Another Ghost or Drive. He stole the Ridewatches from Ōma Zi-O before time traveling to the past.
A minor one from Episode 5 when you think about it: Kondō and Nezu are now good guys to begin with who weren't Gates-turned psychics that were saved by Kamen Riders (in fact it was implied that Zi-O and Geiz are now the first Kamen Riders they have actually met). It could imply that Gates already do not exist anymore at this point, and in turn, Kamen Rider Wizard himself, hinting at the long-existing presence of Another Wizard.
This also doubles as Fridge Brilliance - they met Kondō and Nezu in 2018, and Another Riders are always created in the same year as their series, so of course Kondō and Nezu in 2018 aren't Gates, it's because Another Wizard already exist since 2012!
In a flashback to when the future was altered, Faiz lost his power just as he was about to save Mari from the Elephant Orphnoch. Meaning he probably had no choice but to stand there and watch her get crushed to death.
Possibly avoided as it seems the villains vanish when the riders do like the Scorpion Zodiarts did.
Unless she also vanished because she had no reason to be there.
In D-Video Special: Kamen Rider 4 from Kamen Rider Drive, it was stated that Takumi is only alive because of time paradoxes and alterations. In Zi-O not only is he alive, but also Kusaka who in turn never got revived. This along with Kusaka's personality change raise questions of just how much of a mess time currently is especially with Sougo, Geiz, Tsukuyomi, two versions of Woz, the Time Jackers, Tsukasa and the Future Riders traveling through time or manipulating it every episode.
Or it could imply how messed up the events of 555 were, given that with its events being erased from history, the Orphnochs and Smart Brain do not exist, and the Ryūsei School is just a normal school for orphans, sparing Kusaka the trauma of the Orphnoch attack during the night of the school reunion that started it all, as well as sparing him and Takumi from the events that led them to their deaths.
Takumi seems happy in his life of dry cleaning and is probably a pure human as well. So if history is restored back to normal (or as close to normal as possible), either Takumi dies or he goes back to being Faiz, with all the emotional baggage attached to the title.
The Time Jackers can remove not only Rider powers from history, but they remove their enemies as well. Keep in mind, some of these enemies are not only horrifyingly powerful, but many of them are inherently tied to human history and, in come cases, reality as a whole. The Time Jackers don't even do anything special to accomplish this, they just take a watch and give if to some victim. By just handing over a trinket, these people can warp reality to ridiculous degrees.
The changes to history may just make the Kamen Rider worlds history more like our own. So while they are changing history and reality, they arent necessarily making the current present time worse or better. Just more mundane.
If the Time Jackers succeed in erasing all the Heisei Riders from history, that means the first Kamen Rider of the new era the world will know is the one who conquers it as Ōma Zi-O.
Actually he shouldn't even be alive when he goes help Sougo if we go by the logic that the Rider's enemy is erased also? Takumi is only a Orphnoch when he died sometime before Kamen Rider 555 started and revived as one. If he died, he can't revive as a Orphnoch as Orphnoch doesn't exist so he should still be dead.
Kusaka, as we see in the show, is a nicer person in contrast to his 2003 counterpart.
Nobody would lose their lives to Phantoms, which includes Mayu's family.
The people who died to the Smash, Bugsters, Gamma, Roidmudes, Inves, Greeed and Yummy, Dopants, Fangire, Imagin, Worms, Makamō, Undead, Orphnochs, Mirror Monsters, Lords, and Gurongi are alive.
Although in the case of erasing the Mirror Monsters and possibly the Mirror World, this guarantees Yui Kanzaki's death at the hands of her neglectful parents and with no Mirror World version of her, Shirō would have to live the rest of his days alone.
Yūya Sumii, Ryūji Hase/Kurokage, and the others transformed into Inves are still alive and human.
Actually there's still plenty of Inves in Helheim in the Gaim arc, which only adds more fridge horror - what if the evil that was erased wasn't the monsters, but Yggdrasill? Nobody to study the Cracks, create Drivers and Lockseeds, and put some kind of restraint over Helheim, which is still better than nothing...
Philip, or rather Raito, would have a normal family, though he might have died instead.
However this is mitigated by the fact that Another Riders may even cause more damage than them and that they are all candidates to become the next demon king of the future, but then again that is another kind of horror.
A possible point of travelling to the past to defeat an Another Rider within the brief moment of their creation is to prevent them from starting any damage to begin with. Also unconfirmed, but the defeat of an Another Rider may also erase themselves from history, undoing whatever damage they may have already done up to that point. (Such as when Karin disappeared within mere moments after Another Fourze was permanently defeated in the present.)
Going along with Zi-O being Obfuscating Stupidity, how would Sougo know how to fight as a Kamen Rider? Simple. He goes back in time and sees the entire series himself. Depending on whether you see this funny or terrifying, that means all the battles the Kamen Riders fought from Kamen Riders Ichigō and Nigō confronting and unmasking the Great Leader of Shocker to Kamen Rider Build destroying Evolt, Sougo was hidden, watching them and all of this happening.
What if, while also truly wanting to become a beloved overlord, Sougo manipulated Tsukuyomi and Geiz into sparing him to see what happens so they wouldnt kill him before he gained enough fighting experience to ensure Geiz would be unable to kill him?
If Another Kiva appears and steals Kamen Rider Kivas history, would Wataru still exist or would he never have been born since hes half-Fangire? And if Wataru doesnt exist, its entirely possible the Kiva Ridewatch wont exist too. Sure, Sougo or Geiz can obtain the watch from another source like Kousuke having Wizards Ridewatch but in those cases, the Rider still existed. And with no Kiva Ridewatch, that would make Another Kiva invincible...
For the Ridewatch, not only is it already visible in the ending scene every week when they all spontaneously activate, but given Zi-O is meant to inherit the power of all Riders it's literally impossible that one won't be created. For Wataru, it might be like Terra in Final Fantasy VI, where at the end she became a normal human and just her Esper half vanished. Given how Another Riders work, he'd likely be a normal, violin playing human.
It's a moot point; Another Kiva is created in 2019, and any Another Riders that aren't made in the year of origin of their source won't erase that Rider (i.e; Wataru and the 13 Demon Clans still exist).
If you think about it, everyone, whos not Kaito or Geiz, who were thrown into the Helheim Forest has only two possible fates awaiting them. Either theyre killed by the Inves or they walk around until they eventually cave into their hunger and take a bite out of the strange fruit growing on the trees...
Kamen Rider Heisei Generations FOREVER showed its possible for an Another Rider to attain their respective Riders final form in some way. Another Riders already cause enough problems with their base Rider powers, imagine the destruction a Another Drive Type Tridoron or a Another Ghost Mugen Damashī could cause.
White Woz is a prophet for Geiz Revive, the warrior who defeated Ōma Zi-O. The keyword there is "defeated". Geiz promised Sougo in the previous episode that he would kill him if he started to turn evil, so based on White Woz's new allegiance... that means he did end up killing Sougo. Relatively recently, too, since Shinobi is from the year 2022, a mere 3 years in the future from the current time.
Fans have wondered why Kamen Rider Woz draws power from made-up future Riders rather than ones previously established, like New Den-O, New Kiva, Aqua and Dark Drivenote Or whatever the proper name for the real Eiji Tomari's Rider form is. There is actually a perfectly good reason: Because those Riders' existences are tied to their predecessors', meaning that once Zi-O and Geiz claim their Ridewatches, the events that lead to the future Riders existing never happened. No Ryōtarō Nogami as Den-O, no Kōtarō Nogami as New Den-O. As for Aqua, while his powers weren't tied to OOO, he wouldn't have been given the means to eventually have enough confidence to become Aqua.
Fridge Tearjerker and Horror, but Heure being given the fate of getting involved in a car accident, that's the horror part, absolutely freaks the guy out to the point just seeing either Woz causes him to panic, which is the slight Tearjerker. Sure the guy wants to rule the world/future but that's going a bit far with the punishment isn't it?
The reveal that Sougo has the power to manipulate the future so it happens as he dreams it is horrifying just due to how powerful Sougo really is. Especially since Sougo essentially made Kikai happen subconsciously, a timeline where humanity is driven to the brink of extinction against machines that have taken over most of the world, makes you realize that Sougo is essentially a Reality Warper. It's honestly not shocking that Ōma Zi-O became as bad as he did when you see just how much power he's hiding.
The victims the Another Riders capture are only rarely shown to return after the fact. Some of them get spared due to having to time travel and beat them in their own year, but others are captured in the past right in front of Zi-O and Geiz. When the Another Rider is beaten, their victims don't show up again. And Karin specifically says that she wants Ryūichi, AKA Another Fourze, to stop killing other girls to save her life.
Kamen Rider Woz Futuring Kikai has an ability to turn nearby humans into Semi Humanoise. While the Humanoise are evil androids in the future, taking account to the word Semi, does that mean White Woz's Semi Humanoise are actually suffering from Unwilling Roboticisation?
The fact that Kamen Rider Woz Futuring Kikai has such an ability implies Rento also has or had this ability, as Woz is using his powers. A little WMG here, he may even have been used as a tool by the Humanoise to get close to humans and when the time is right, a signal is sent to turn him back into a tool of the Humanoise and convert all nearby humans into Semi Humanoise.
What in the world happened to Sougo's uncle in Ōma Zi-O's timeline? Is he working for Ōma Zi-O, did he rebel, is he still alive? It can even be possible that his death could have become the catalyst for Sougo to turn into the Evil Overlord he's known for in the future.
What if Tsukuyomi and Geiz abandoning Sougo was the catalyst for Sougo to become Ōma Zi-O? Had they just trusted Sougo a bit more, believe in him to make the right choice, and stayed by his side, maybe Ōma Zi-O never would have been born.
Or rather, with the reveal that Tsukuyomi was the one who seemingly orchestrate the bus accident that Sougo and Hiryu were inside, does this mean that the whole Bad Future thing was Ōma Zi-O throwing his temper tantrum at humanity for all the miserable things happened in his childhood?
It's since been revealed that it wasn't Tsukuyomi who caused the bus crash, it was Swartz who was the man Sougo saw in his dream who inspired him to become a king.
Episode 32 reveals that Time Powers aren't naturally born with unless you're Tsukuyomi or Swartz. Meaning Sougo's powers had to be given to him by Swartz.
With the disappearance of White Woz due to his timeline isn't exist anymore, what is happening to Kamen Rider Shinobi and Quiz? Are they even exist especially for Kagura in Rider Time: Kamen Rider Shinobi and after Mondou reunion with his father?
Considering they probably hail from random timelines created by Sougo unwittingly due to his time powers, they're probably just fine.
What about Geiz and Tsukuyomi? What are the chances that if the timeline gets changed so much that they also endangered their existence in the future?
Ōma Zi-O's main color is gold compared to our Zi-O's silver. But the more upgrades that Sougo gets, the more gold gets incorporated into his suits. Zi-O II has some gold highlights while Zi-O Trinity has streaks of yellowish gold throughout his body. Almost if Sougo's power is corrupting Sougo. Makes sense why despite all the various changes to the timeline including creating a powerup that didn't exist, Ōma Zi-O still exists.
If creating Another Rider erases not only the Original Rider's powers but also their enemies shouldn't that mean Takumi should be dead by the time 555 started let alone the year that Zi-O rolls around? He is only a Orphnoch because he died when he was a kid but revived as one. If Orphnochs are erased that means he should had been dead as he can't become a Orphnoch as they are erased or am I missing something?
If that is the case, doesn't mean that Takumi's encounter with Mari, his rivalry with Masato and friendship with Kiba shouldn't be exist either?
Based on Kamen Rider Den-O's workings of time, it seems that time is trying to keep itself in order, so if character A lived, then time alters things so that character A lives in the new timeline, even if the Another Rider removed their survival method. Likely, Takumi was only in the hospital for a long time as a kid instead of dying. Similarly, a lot of the Fangire characters are likely turned into humans, so Wataru's mom is a human too, and she may have simply had an awful divorce with her husband (if he's anything like his original self) and rebounded with Otoya.
