Moment Subpages are Spoilers Off. You Have Been Warned.

  • The Another Riders.
    • They are your favorite Riders of any year, twisted into horrific, grotesque knockoffs of their former selves. One of the enemy generals gives people a genuine choice if they wish to become an Another Rider or not. The other? He just turns you without your consent. It’s later revealed that even if the offer is turned down, the Time Jackers will force the Another Watch on them anyways. The only reason they bother with the choice is because forcing it is more likely to create a mindless monster.
    • The people who became Another Riders are average people who get to live the dream so many of us have. To be given the power of a Rider. However they prove unable to contain it, and become a twisted monster version instead. The dream becoming a nightmare. Now imagine if this happened to you. Not to mention how they're recruited (or at least, how one of the generals recruits you, if they have different methods.) Imagine you're facing certain death, such as a car speeding towards you, Too Fast to Stop. Then everything stops, and you're given An Offer You Can't Refuse by the perfectly-human-looking figure who hit the pause button: history says you died right now, but you'll be saved if only you accept the contract. You're given no details beyond that: it's either take the strange watch-thing being handed to you or you've got about half a second of life left. So you do. Then you're told you're going to be a Rider! Then... yeah.
    • What's stopping any of them from coming back? These are human beings not kaiju that can be killed off. So what's stopping any of them from going after Sougo? Or trying to get their powers back? Most of the time, it's the person's own morality. Some of these people are genuinely horrified by what they did as Another Riders. Others however, are genuinely evil bastards and when push to shove. Will the police do something? Or will the riders be forced to kill?
  • Oma Zi-O, the future Zi-O, is really quite terrifying.
    • From the description alone, he is said to be so powerful that no-one in the future is able to defeat him and he easily crushed any resistance against him. Considering that Zi-O is a rider who can use the power of past Riders, this means that Oma Zi-O probably has full control over said powers. Just imagine how powerful that would make him. No wonder he's called the "Demon King".
    • The Bad Future that Zi-O rules. Not only does it utterly terrify the current Zi-O to the point of actively doing everything he can to prevent it, but Geiz, the secondary Rider this season, was sent back in time to kill our hero before he has the chance to become the demon king just in case. Only through the intervention of the girl from the future suggesting that they might be able to prevent the timeline through peaceful methods as well as seeing Zi-O's resolve convinces Geiz to not act.....for the moment at least.
    • As the series continues, we see Sougo gain more and more time powers with some of his powers making him a full on Reality Warper. The saving grace is Sougo both doesn't have full control of these powers yet and he's too good natured to truly abuse them... for the moment. But Oma Zi-O lacks both of these restraints having had 50 years of practice with these powers as well as being deranged enough to abuse them to their full extent.


    Episode 1: Kingdom 2068 
  • We get a glimpse of the Bad Future that Oma Zi-O rules and how powerful he is. He’s able to kill people just by waving his hand, easily destroys an army of Time Mazines and even disintegrating humans without a breaking sweat. No wonder he's able to rule the future without anyone to truly challenge him.
  • Also, after Another Build is defeated, he returns to normal. The same cannot be said for the people who he had absorbed into Smash Fullbottles while in his corrupted state, who do not reappear. It's still just episode one so we can't be sure we won't see them restored next week, or even that all Another Riders have the same MO, but from the looks of it, Another Riders are driven to transform people into more of their Transformation Trinkets to increase their powers, and they can do so with a gesture, and there is no saving these victims.
  • What is going to happen to the basketball player after he is truly rescued? Will they just let him lives his life after literally losing a year of his life and causing him to live with the guilt that he had done or will they dump him back in his time and let him get run over by that car? The main characters seemed to want to avoid causing changes to the timeline unless it is necessary to their goals. It will be kind of horrifying and sad that the basketball player gets rescued from being Another Rider Build only to die from the fate he wanted to avoid the first place. Episode 2 defuses this by showing that he simply returned to the past in the position he was in when Heure froze time, complete with the car being displaced from where it was originally.
  • Poor Sougo being attacked by Geiz before he knew the truth. Imagine being attacked by some random guy for doing something you hadn't done in the past but something you would do in the future that you hadn't even done yet!
  • Sougo's first reaction to becoming an Evil Overlord of a Bad Future he caused is happiness, because he managed to achieve his dream while only being bummed that he's an evil king. This really makes you wonder if something is wrong with him.

    Episode 2: Best Match 2017 
  • Another Build's face is a bit too terrifyingly expressive as it turns people into Full Bottles.
  • We get a really nice look into the true horror that Another Riders provide for us. They're basically immortal unless killed in their original time by using the Ride Watches of their namesake Riders. Every time Another Build is blown up, yet another Build will walk in from off-screen like a demented Animaniacs parody.
  • Yet another horror they bring is the fact that the longer they exist, the more they take the place of the Rider whose powers they have. As far as the timeline is concerned, the monstrosity that is Another Build actually is Kamen Rider Build and not Sento! Even worse, Sento himself is erased out of existence - the man that has Sato Taro's face is called as, and refer himself as, Takumi Katsuragi.
  • The main characters come face to face with their first Time Jacker, Heure. He proves his credentials by pausing time for everyone except himself, Sougo, and Geiz. He then pouts and asks what the heroes are doing as if they were simply interrupting his television show, rather than saving the timeline. And when Sougo gives him a philosophical take on why he was wrong for turning the basketball player into Another Build, he acts as if someone beat him in a 'which Transformer is cooler' argument and then skips away in a manner too reminiscent of Gremlin.
  • Another Build straight up ATE the bottles he's holding, that are actually living people turned into essence. When he's defeated, he's turned back into a normal human, but once again we saw nothing about the two other people he absorbed.

    Episode 3: Doctor Gamer 2018 
  • Ora talks with Heure about their plan to rewrite time as if it were some sort of game and now it's her turn to play. And then we move to 2016, where Ora is telling a man that his sick son is going to die unless he becomes Another Ex-Aid.
  • Whenever somebody reaches a certain point in the game rumored to be unbeatable, the screen flashes a bright pink. For a second, they’re dazed but then they look up... and see the monstrous Another Ex-Aid standing in front of them.
  • Another Ex-Aid, just like Another Build and Sento, is a twisted mockery of Emu. Instead of curing diseases, Another Ex-Aid afflicts whoever plays the unbeatable game to a certain point with a disease that leaves them in a coma while doctors have no idea how to treat them.

    Episode 5: Switch On 2011 
  • Another Fourze absorbs a girl into a Astro Switch and reacts as if he's just had his drug fix after a long time.
  • Another Fourze is defeated so everything is going to be okay, right? Wrong. Another Fourze just sheds his Fourze suit, revealing him to be Another Faiz!

    Episode 6: 555・913・2003 
  • The modus operandi of Sakuma AKA Another Fourze/Another Faiz as well as the reasons behind his transformation are quite disturbing. After his friend, Karin Yamabuki, was killed in an accident (in fact, her corpse is shown on-screen during her wake), Sakuma became an Another Rider in order to revive her by draining the life force of other women. He's been doing this since 2003 and a brief montage of all the women he'd killed for Karin really drives home how prolific a body count he'd amassed. Then there is when he got the AnotherWatch, it cuts to Faiz's fight with the Elephant Orphnoch. Specifically, when Faiz is about to use Crimsion Smash as the Elephant Orphnoch is charging towards Mari to crush in a wreck car. Then Takami suddenly loses his Faiz powers...

    Episode 7: Magic Showtime 2018 
  • While a joke at first, Another Wizard, when thoroughly pissed off, shows how dangerous Haruto’s magic would be in the wrong hands.
  • Time Jackers have always used their Time Stands Still ability to evade notice from anyone outside their target, but Swartz shows what they could really be capable of if they only tried, by pushing Geiz over the edge of a building when he's frozen yet conscious of what’s about to happen.

    Episode 8: Beauty & Beast 2012 
  • In a rather huge case of Poor Communication Kills, Hayase could not confess his feelings to Kaori at first and just assumed helping her keep her late father's theater running would make her happy. Kaori however, had just been proposed to by their co-worker Nagayama then, but it took her 6 whole years to gain the resolve to shut down the theater and accept him, all while Hayase was kept out of the loop. Needless to say, he went mad from thinking he had been exploited for those 6 years after he found out. Worse still, as he haunts Kaori for revenge, he still does not explain himself, only yelling at her "Why don't you understand my feelings!?" As terrified as she is, Kaori really could not have understood what had she done to deserve this.
  • We get to see the full extent of Sougo's cunning and manipulation, being able to use Geiz and even Woz, of all people, as unwitting pawns to achieve a satisfactory conclusion for Another Wizard's case. Geiz takes this as a hint that Sougo might just actually become Oma Zi-O in the future.

    Episode 9: Genm Master 2016 
  • How about the fact that the Time Jackers are now going to choose people who are determined as Another Riders, because Zi-O rose through power by believing in his right to become king. The Another Riders up till now were all desperate or emotionally weak people and as shown with Kuroto Dan as Another OOO, it's clear now that the Another Riders we are going to see next are going to be more dangerous, because they are doing it out of their own will!
  • Kuroto, of all people, is Another OOO. Heure has picked the memetic madman]] and is little too excited to find out about the whole insane part. Let that sink in for a moment. He easily kills his father in 2016 to usurp his position and power. Said father was Masamune Dan, the true Big Bad in the original Ex-Aid timeline, now retconned to a defenseless CEO who gets offed by his son after he became the monster. Also considering how Kuroto picks up his father, it's highly implied he killed him by snapping his neck.
  • Likewise, Sougo is little too excited to become Kuroto's apprentice.
  • If #8 didn't convince you Sougo can be Oma Zi-O, the obvious lack of effort on his part as he dispatches Geiz attempts to attack should be enough. Every blow is nonchalantly dodged. A single kick connected ... and turned the Ziku Driver, completing Sougo's transformation. The following fight left Geiz down for the count and walked/dragged away by Tsukuyomi.

    Episode 10: Hawk Tiger Grasshopper 2010 
  • It turns out Kuroto Dan's primary motivations as Another OOO stemmed from his father, who was just as ruthless and power-obssessed as he is. Once obtaining power as Another OOO he goes on to eventually kill Masamune out of spite 6 years later for all the stress and Parental Neglect placed onto him as his son, ursurping his power and falling down the same power-hungry route his father has gone as a result. The evil truly runs in the family.
  • This also hints at exactly how much the original Rider storylines were necessary to the world. Without the Bugster Virus Kuroto wouldn't have been able to preserve his mother, who was his Living Emotional Crutch. With her dead and him unable to revive at least her memories as a Bugster, He wound up becoming worse than his main timeline counterpart.

    Episode 11: Zi-O On Parade 2018 
  • Asura/Another Gaim traps members of Team Baron who don't agree with him in Helheim Forest which is pretty much a guaranteed death. And as for those who last, like Kaito? He survived five years in that place and hasn't become an Inves or eaten a Helheim Fruit. Which raises the question of what he could've been living on.
  • In the Cold Open when Sougo defeats Another Gaim, Kouta uses his powers to take Sougo to a hidden dimension of some sort before tossing him back in time. It's a weird Eldritch Location which reminds us that Kouta is a Physical God of an Eldritch Location. Brr.
  • The scene with the clock mask dancers is a lesser version of this trope, instead going for an Uncanny Valley approach. The way that the dancers move, the way they completely ignore the three oddly dressed individuals around them even when time resumes, and even their Dissonant Serenity all can send a shiver down your spine if you focus a bit too much on them. Bonus points for the eerie atmosphere generated by the Time Jackers trying to make Geiz perform a Deal with the Devil.

    Episode 13: Ghost Hunter 2018 
  • Based on the episode description, Geiz is now fully determined to get rid of Sougo no matter what. And Sougo dies during the episode, based on the trailer. ...make of that what you will, but the implications are quite scary.
  • Takeru was always sorta Creepy Good appearance wise. Another Ghost, meanwhile, ditches the good and dials the creepy up to eleven.
  • The fact that Woz has decided to ally with the Time Jackers to manipulate Sougo into becoming the Demon King. And the fact that his main plan do so is to have them call in Kamen Rider Decade.
  • While not as bad as most examples in this episode, Tsukasa Kadoya is a more subtle example. It's obvious that he's mastered the powers of the Riders he's already acquired, dominating both fights he's involved in as both Agito and Hibiki. The fact that he's adopted a baritone helps set this apart from his past Face-Heel Turns.

    Episode 14: Go Go Ghost 2015 
  • The preview for the next episode contains the worst thing Oma Zi-O could possibly say, sending all of Sougo's hopes and dreams crashing down around him with a single line:
    Oma Zi-O: I am the greatest and most beloved overlord of all time.

    Episode 15: Back to 2068 
  • The series has been building up to this moment where Sougo finally meets his future self. Him not taking it well would be an understatement.
  • Oma Zi-O's Curb-Stomp Battle on Zi-O is where Past! Sougo was brought down to his knees. What worsens the situation is that Oma Zi-O accesses the powers of his predecessors by simply activating the Ridewatches. Right after he did, he unleashes bigger and badder versions of attacks Zi-O uses.
  • Oma Zi-O has control over Ryuki's contract monster, Dragreder. This is especially horrifying for fans who watched Ryuki since they know how terrifying a threat a Mirror Monster is since not only can Dragreder appear in places with reflective surfaces which is basically everywhere, but Mirror Monsters also need to be fed by the energies of other Mirror Monsters or people. Oma Zi-O can pretty much just summon Dragreder and order him to appear in front of someone who could be a threat to his rule and kill the person without anyone knowing what happened since there is not even a body left for someone to find.

    Episode 16: Forever King 2018 
  • Sougo is so determined to protect people that he finally convinces Geiz that he can be a good overlord. Makes one wonder what happened to make him Oma Zi-O, who appears to be above morality just like he is above everything else.
  • Sougo actually went and had his Driver destroyed! The trailer made it seem like it'd be a fake-out but he actually did it. We then cut to Oma Zi-O in the future and he's laughing when he's disappearing from existence. He's not worried about his demise, but instead laughs like a plan just worked completely as he expected it. This also confirms that Sougo truly is Oma Zi-O's past self since his destruction of the driver is what caused him to Ret-Gone.
  • We cut to the future once more after Sougo renews his vow not to become Oma Zi-O. In there we see Oma Zi-O restored from existence, laughing since he knew that his younger self wouldn't be able to cast aside his dream. This confirms he's also a chessmaster in addition to his role as demon king because he expected everything that would happen. This gives even more proof that Sougo is Oma Zi-O since even in the present he has shown to be quite manipulative.
  • Tsukasa, the man whose series had the highest Rider mortality rate, has a plan. For Sougo. For the full impact of this to set it, remember who we're talking about. Kadoya Tsukasa, the incarnation of the Great Leader of Shocker, the man who killed every Rider that came before him singlehandedly in armed combat with no support, the man whose idea of 'teaming up' involves beating up EVERY Super Sentai team in existence at the time so hard they get punched into another dimension, the man who destroys universe just by standing inside hem for too long, who tries to do good while at the same time still having a personality totally fit to be the Great Leader of Shocker, has a plan for Sougo. Have we just discovered what traumatized Sougo so hard he became an evil overlord?
  • Woz himself becomes creepier halfway through the episode, from the moment he starts urging Sougo to take the belt, to the moment he gives the epilogue of the episode and we are shown a shot of the new Kamen Rider.
    Woz: Now the players are all in their place... The course of history is about to go through great changes.

    Episode 17: Happy New Woz 2019 
  • The concept of Oma Day. The day where Sougo supposedly finally rises to power, and as a result, every Rider before him just disappear, leaving him the last one. The mere thought of it is terrifying - one day, someone rises to power to become the most iron-fisted ruler of all, capable of causing wanton destruction with the wave of a hand. And all of a sudden, the heroes bent on protecting humanity... just gone.
  • Through the entire episode, Woz doesn't crack a single smirk, while Another Woz is enjoying his control of future more than he should. For Woz, the guy who can smirk in the darkest hours, who clumsily slips the future in the episode intro, who has the answer to nearly anything, to be this concerned, things are about to get much worse.
  • Once written down, the future Another Woz makes cannot be changed unless Another Woz wills it. If he writes "You will get into a car accident", it will happen and your attempts at stopping it will fail. Heure continuously stopped time only for time to restart again and when he moved out of the way, the car coming for him simply teleported. The fact that Another Woz did this to a child makes it all the more terrifying. To further add to the terror, Another Woz was about to write Zi-O's defeat by his hands, if their Woz didn't make it in time to stop him, nothing would have.
  • Another Shinobi. Imagine a monster that can hide in the shadows and kill you when you least expect it in the most unpredictable ways, and you have Another Shinobi. He also serves as yet another example that the corruption by Anotherwatches is absolute. Rentaro is shown as a caring person who wants to be a hero. As Another Shinobi, he is a monster that murders people from the shadows.
  • The existence of Another Woz is a major sign of worry for three of our main characters:
    • Sougo - While this means a better future is possible, it comes at the cost of his death by Geiz's hands. Also due to the fateful Oma's Day where this happens being set in 2019, it implies he has less than a year left to live should Another Woz's timeline come true.
    • Geiz - The inverse is also true for Geiz, who at this point wants to stop Oma's Day without having to take Sougo's life, if possible. Unfortunately for him, Sougo will die by his hands, according to Another Woz's history. Also he is visually uncomfortable with being heralded as a savior/messiah for having "done" so.
    • Woz - Not only is there a risk of Sougo not rising to power as he had hoped for, but having an Alternate Self puts his entire existence at risk as he would be completely wiped away from history and replaced by Another Woz should the new timeline come true.

     Episode 18: Fantastic! Historic! Futuristic! 2022 
  • Rentaro questions what he's doing as Another Shinobi, killing bullies and thugs, and wonders if he's really protecting the weak. Even with the Another Watch's corruption, Rentaro is conscious enough to realize that what he's doing isn't what he wanted at all. But he can't stop himself. He's no longer in control of himself as long as he's Another Shinobi, only getting a few moments of reprieve whenever Zi-O defeats him.
  • Heure sounds about ready to freak out when he sees Woz, only to calm down when he realizes it's the original Woz. Another Woz traumatized Heure, a child, to the point he sounds scared upon seeing Woz's face.
  • Woz's concern is not unjustified, and is doubled when Sougo suddenly feels tempted to look for Another Shinobi, he knows it must be a trap and voices his concern. It's not just that his beloved overlord is threatened, but he is clearly afraid of the future that these actions will create.

     Episode 20: Final Answer? 2040 
  • White Woz takes another step towards being a Nightmare: He forcibly takes Mondo's Quiz power to make the Miridewatch and defeat Another Quiz. Thankfully he retains his power, if the belt and pendant are hints of that.
  • And then it's Geiz's time to be creepy by having a vision of his future as Geiz Revive, which makes him look quite ominous, and walks away like he had his strength drained. He doesn't come back to 9' 5' Do either.

    Episode 21: Mirror World 2019 
  • The opening scene shows Heure making a contract with Dark Shinji. The mirror sound note  makes it even more eerie.
  • Breaking a contract in Ryuki means being eaten a mirror monster. One would wonder if it can happen to Another Ryuga or Heure.
  • Sougo has a mirror version of himself:
    • Said mirror version is also played by So Okuno, per usual when it comes to mirror selves. He pulls off possibly one of the most menacing faces in the entire franchise.
    • The announcement of his Ziku Driver is not just vaguely menacing, it's positively demonic. He tries to murder Sougo right after transforming and if he succeeded, no-one would know about that but him.
    • We all know this is not going to happen and not everything from Ryuki is enforced, but still Sougo's chances in the Mirror World are just as well as snowball's chances in hell. There are mirror monsters, a time limit after which anyone from the real world dissolves and one can only exit the way they entered and if they have a Card Deck, (probably) the Ryuki Rider watch or hold onto Another Ryuga, which is how Sougo got in.
  • When going to Shinji's place, every single reflective surface in the room has been covered, every window shut, and not even a single beam of light is able to pass through. Shinji has grown this paranoid of Dark Shinji, and not without reason. When he wakes up in hospital, he immediately bolts to cover the window and screams at seeing his reflection in mirror. This all causes him to run away from the room, but then it gets even worse, as he encouters White Woz, who throws him down the stairs and tries to murder him.
  • Another Ryuga itself is a living nightmare. You cannot make a Ryuga Ridewatch to defeat him since Ryuga is from a different world altogether instead of a different time, he can reflect all your attacks due to his mirror-based power, and he emerge from any reflective surface, which are practically everywhere even inside Sougo's house. And oh, the host is none other than the real Ryuga himself who is a full on villain, so unlike say Shinobi, you can't even try to expect any form of cooperation to somehow create the Ridewatch.
  • White Woz would straight up murder Shinji Kido, a defenseless civilian in this timeline, to get rid of Another Ryuga if Geiz didn't stop him.

    Episode 22: Zi-O's Strongest! 2019 
  • So Okuno manages to pull off a perfect "Dark Sougo", giving one of the most evil smiles in the episode, exceeding his performance in the previous episode.
  • Mirror Sougo looming from every reflection. Let's remember how many reflective surfaces are in 9' 5' Do. He tortures Sougo by mocking all his decisions and beliefs. It looks like Sougo is just barely holding his marbles together all the while.
  • Sougo suffers a case of Power Incontinence that applies to his social skills rather than his superpowers, accidentally convincing Geiz to use a suicide attack to beat Another Ryuga. Mirror Sougo accuses this of being no accident: deep down inside Sougo knows Geiz is just in his way and wants to use the situation to either be rid of him once and for all or to gain the power of Oma Zi-O that he craves.
  • Geiz, having been convinced by Sougo to try the suicide attack, actually goes through with it, and it's implied to be at least partially a case of being Driven to Suicide by the guilt over how he'd actually seriously considered White Woz's suggestion of murdering Shinji to get rid of Another Ryuga.
  • Sougo's nigh-emotionless response to seeing Geiz dead in Tsukuyomi's arms is rather unsettling, especially after the whole 'accepting his darker side' thing and the fact that one might expect the usual Sougo to be frantic and distressed at the sight of a friend's corpse. It's a particular contrast to Tsukuyomi's distraught state, and she also reacts to it.
  • Sougo's Zi-O II form is spiffy-looking and very powerful, but everyone except Black Woz is terrified by what they see, for a number of reasons:
    • Before he even uses the Ridewatch, just having it in his hand is enough to let Sougo casually reset the timeline to a point just before Geiz attacks, halt Geiz's kick in midair and then rewind time so it fails. To repeat: Sougo erased a timeline, and made a new one. Tsukuyomi freaks out at seeing this and decides that Sougo has to die, for good reason: how often did she see Oma Zi-O just undo any event that displeased him?
    • The Zi-O II costume is much closer in silhouette to Oma Zi-O's. The implications speak for themselves. Its silhouette is made more sinister yet by the cold stare Sougo gives while transforming and the speech he delivers during the battle about accepting his evil impulses as part of himself. In the context of the wider episode, it's because Shinji teaches him that accepting those dark feelings is the first step in moving past them, but none of the other characters were there to see that, and absent that context it sounds much more like a declaration of Then Let Me Be Evil.
    • White Woz's composure snaps in a way that's never been seen before when Zi-O II takes the field. He grabs Black Woz by his clothes and shakes him, demanding answers, and then when no answers are forthcoming, he bolts and leaves Geiz behind. Either it was just a strategic retreat to prepare countermeasures or Oma Zi-O never had this power, and either way White Woz realizes his control of the situation has just been completely upended. In his pursuit to ensure the security of his future, he might have given the greatest tyrant in all of history even more power. OOPS!
    • The fact that White Woz is still around means that even with all the powers that Zi-O II demonstrates, Geiz Revive still has a shot at killing him. If Zi-O is this powerful and he's not even Oma Zi-O yet, how powerful is Geiz Revive? It's rather scary to think about.

    Episode 23: It's Kikai! 2121 
  • Tsukuyomi lost faith in Sougo and allied herself with White Woz, even trying to convince Geiz that this is their only chance.
  • A minor one, but Geiz freaks out when Junichiro tells him that Sougo said he's seen his tests will turn out ok. While this was just Sougo's big mouth running off (he sucks at studying after all) and doesn't mean anything to his uncle but a joke, it reminds Geiz that Sougo is so powerful now he really can predict the future. He has a prophetic dream every time he falls asleep in this episode that reaches further into the future than either Woz can see in their records.
  • Kikai's future might be even worse than Oma Zi-O's: Humanity is secluded to a small space and, while in there it looks like a peaceful world, the truth itself reveals when Humanoise attack. They look like any human being but are jarringly mechanical in their movements and speech and ask if their target is a machine or a human. Regardless of the answer, they already know and attack to kill. They're basically Monster of the Week style Terminators.
  • Another Kikai isn't like the others, it is a plant-like parasite that latches on its host and mutates it into Another Kikai. It is not so terrifying when the host is a tree, but when its host is something else the last thing they see is Another Kikai's parasite latching on to them. On top of that, there's the matter of the fact that none of the Time Jackers created Another Kikai. None of them know where the Another Rider came from or how it functions. Where did it come from?
  • Swartz shows how much of a monster he can be by taking Another Kikai's face and pushing it onto Heure's face, despite Sougo telling him to run. Heure is terrified to the point he could probably cry if he had any time to before the young Time Jacker is mutated into Another Kikai. Ora witnessed it all, in sheer shock at Swartz's cruelty. Sougo sees a hazy vision of this happening when checking for a future encounter with Another Kikai. When it's about to happen, he has just enough time to yell at Heure to run, but Swartz doesn't give him any chance. Heure seems to realize something's wrong after hearing Sougo actually use his name, but by then its too late and Swartz has jammed the Another Kikai parasite on his face.
  • The last dream of 2121 Sougo has: Kamen Rider Kikai is reprogrammed when pinging a satellite for energy after an exhausting fight, effectively becoming a Humanoise in the body of a Kamen Rider. Rento generally avoids falling into Uncanny Valley as the only real indication that he is not human is a soft electronic noise accompanying his every movement. But after reprogramming which involves being forcibly transformed into Kikai, he moves with Marionette Motion, his visor glows and he abruptly swings his head very close to the camera when delivering the Humanoise question. Easily outcreeps them all.

    Episode 24: Best Friend 2121 
  • It turns out the supposed anti-Humanoise meeting/safe zone is actually led by Humanoise. This could mean two things, one this was a trap the Humanoise created to gather humans or two the Humanoise knew about the meeting, invaded it, killed and replaced every human present there, because they were able to know it thanks to the radio transmission. It's truly clear that in this future, you can't trust anyone too much.
  • Due to Ora's manipulation, she is able to fully control Another Kikai and lets him run rampant as the heroes are stuck in time. This results in Another Kikai shooting missiles at the the frozen in time Tsukuyomi as both Tsukuyomi and Geiz are screaming in horror at her death. Luckily it doesn't stick due to Sougo resetting the timeline but still.
  • Futuring Kikai demonstrates the ability to brainwash people en masse and turn them into robots. Sougo's powers might be terrifying, but White Woz is no slouch himself.
  • The reveal that Sougo doesn't see the future in his dreams so much as he's actually creating future events as he sees in his dreams without realizing it. Another Kikai was created by him, a monster made out of his subconscious fears and stresses about his friends abandoning him. Tsukuyomi is horrified by the sheer power Sougo has and is even more determined to ally with White Woz as a result. This might actually completely backfire on her, as since fear is making her and Geiz keep distance from Sougo...who the hell is going to keep Black Woz's influence on him in check? For that matter, if Kikai and Another Kikai are from a future Sougo created, who's to say his is the only one Sougo made? White Woz didn't arrive until Sougo saw Shinobi's future in his dreams. Is the entire Geiz Revive future a product of Sougo's terror at having seen himself as Oma Zi-O, wanting to create someone who could kill him?

    Episode 25: Another Zi-O 2019 
  • Ladies and gentlemen, we finally have Another Zi-O. And he is every bit as terrifying as all other Another Riders who have proceeded him.
    • His overall design is demented. Especially the faceplate. That isn't just a helmet, it's a face, or rather it's a face without the skin!.
    • Just like Sougo and Geiz, Another Zi-O can also use the powers of other riders. More specifically, every Another Rider that has been defeated up until this point.
    • And just to make things worse in his Another Zi-O form, he shares Zi-O II's future sight ability
  • According to the episode synopsis, Another Zi-O is targeting every person who has made a deal with the Time Jackers. Whether its a case of Your Soul Is Mine! as payment for their services or something else, it is terrifying to know that people who previously went crazy with power end up being targeted. After the events of the Kikai Arc, Heure and Ora are naturally wary of Swartz. Especially when they ask him if he's the one responsible for creating Another Zi-O in the first place.
  • Sougo remarks that he's almost happy about the attacks because it gives him a chance to see Geiz and Tsukuyomi. While that is a little questionable, he does quickly note how twisted it is and that he's not actually happy that people are being attacked. Black Woz, however, seems quite delighted by the concept of Sougo enjoying others being hurt in any capacity, and encourages it. Which gives a very reassuring impression of Oma Zi-O's views on the subject.

    Episode 26: Geiz Revive! 2019 
  • The sheer ambiguity of what happened in the bus where Sougo, Hiryu, their parents and Tsukuyomi were inside. In the preview we seemingly saw Tsukuyomi pointing her gun at a young Sougo. According to Hiryu, she was the cause of the accident and since she came for Sougo which became the reason he blames Sougo for the accident. Highly implying that Tsukuyomi was in a way responsible for it and even if she wasn't, what in the world happened their for her to use an armed weapon in a narrow space full of people. What makes this even worse is that Geiz saw everything, but couldn't save her. When the bus crashes and explodes, he thinks she died and gains the resolve to use Geiz Revive, fight and kill Sougo.
  • Geiz is scary when he appears in the fight between Another Zi-O and Zi-O. He charges Another Zi-O and punches him hard enough to knock him down and that's before he transform into Geiz Revive and nearly one-shots him. All with a Thousand-Yard Stare and Tranquil Fury. After Another Zi-O runs, he turns to Sougo and just declares he is going to defeat him when asked what happened. Seeing there is no way to avoid conflict now, Sougo seriously agrees and they fight.
  • As it turns out Tsukusa Kadoya/Kamen Rider Decade was also on the bus which only questions why he didn't stop the bus crash. He couldn't, thanks to Swartz.

    Episode 27: The Beginning of Everything 2009 
  • It turns out Swartz was also in the bus, but the true question is why and how? The answer is he's started the entire mess by causing the bus crash that orphaned Sougo and Hiryuu, framed Tsukasa for the incident, and even back in 2000 was trying to find the best candidate to be his overlord.
  • While the reveal that Tsukuyomi wasn't killing anyone in the bus is a major Nightmare Retardant, it comes after the terrifying scene in the previous episode, Swartz freezing every adult in place and causing the bus to move uncontrollably while a visibly concerned Tsukasa tries to steer and stop it, and the fact Sougo is in danger after trying to attack Swartz.
  • The fate of the adults on the bus; as Swartz froze them in time, they are either unable to do anything as they went to their deaths, or if their minds were frozen as well, completely unaware of their own fate. Perhaps even more disturbing, they have no idea that their children survived the crash, so the adults all died thinking their sons perished as well.
  • Hiryu can turn people into Another Riders by pushing Another Ridewatches into them. He's no better than the Time Jackers at this point.

    Episode 28: Our Goal 2019 
  • If Geiz getting a Psychic Nosebleed and bleeding out of his ear in the last episode was scary, then seeing him crying Tears of Blood after beating Black Woz due to the strain of Geiz Revive is terrifying. The fact that he's not Overdrawn at the Blood Bank and instead has a small amount of blood coming out of his tear ducts only makes it worse as it makes you imagine what it must be like on the inside since he can barely even stand from the pain.
  • After Zi-O II and Geiz defeated Another Zi-O, Hiryu seems to have lost his drive to kill Sougo. As this is happening, the Another Zi-O Ride Watch starts to break into pieces only to reassemble. Indicating that this is not the last time we'll be seeing Another Zi-O.
  • It might be for greater good, but Tsukasa flatly said he would destroy the world if Sougo does ended up become Oma Zi-O as if he was talking about the weather. No wonder he doesn't seem to care for those children (or their parents) who were killed on the bus.

    Episode 29: Blade Joker?! 2019 
  • This episode has Blade and Chalice meeting up again... which is a very bad thing. If they were to ever meet again, the Undead Battle Fight would restart... and since both are Joker Undead...
  • Continuing the tradition of Another Riders being nightmare fuel, Another Blade is another horrifying abomination, this time with human-like eyes that look like their eyelids have been peeled off and a sawblade on her sword. It's so unnerving to look at that for a while, this folder had its own image.
    • The eyes either become more or less unnerving with the knowledge that Another Blade's facial expression is based on Hajime's infamous, memetic "I will kill you!" face. Nevertheless, it's almost impressive that the designers took one of Blade's well-known memes and managed to turn it into such a spine-chilling Nightmare Face.
  • Another Blade is Amane Kurihara. Hajime left her for places, and reasons, unknown and while she seems to be okay on the outside she goes completely batshit crazy right after having the Another Watch put in. Once she becomes Another Blade she goes from just "merely" super attached to near Yandere levels of obsession.

    Episode 30: 2019: Trinity has Begun! 

    Episode 31: 2001: Awaken, that Agito!  
  • Another Agito, good lord. Unlike other Another Riders, which are based off of Primary Kamen Riders and replace their history, their creation follows the rules established by Agito. Namely, there can only be a single "Kamen Rider Agito" active. Anyone else just becomes either an offshoot creature like Gills or the original Another Agito. While this means that Shouichi isn't entirely affected by the Anotherwatch making alterations to his timeline, it means that the Time Jackers' Another Agito can exist in hordes. Worse, they increase their numbers like how zombies would: by biting their victims and transforming them as one of their own. The first time we see someone be infected is one of the G3 units, who the Another Rider tears open like a tin can to get something it can bite. The G3's screams, amplified by his helmet's speakers, are absolutely haunting. Not to mention he then pounces on an unarmored officer as the camera pans away like a Gory Discretion Shot as his screams of horror fade away.

    Episode 32: 2001 Unknown Memory 
  • This episode brings up rather some uncomfortable reveals and questions about Tsukuyomi and Swartz. Woz reveals that time powers can only be given and thus both he and Ora wonder if Swartz is trying to turn Tsukuyomi into a Time Jacker. Even more unsettling is Swartz stating he has nothing to do with Tsukuyomi's powers developing, begging the question "Then who is?". The reveal that humans don't get time powers naturally brings up the question of how long has Swartz been manipulating Sougo? A few more more important questions can be raised from this; how the flying fuck did Swartz get time powers? And what in God's name does he mean by he and Tsukuyomi are 'cut from the same cloth'?

    Episode 35: 2008: First Love, Wake up! 
  • Like several villains or villainous things in Zi-O before, Kamen Rider Ginga just came out of nowhere and tried to destroy the world.
  • A minor one which can be overlooked, but this episode as Sougo force-transformed into Zi-O Trinity without neither Geiz nor Woz's consent. When pushed to his limit, you could tell that an assertive part of Oma Zi-O is silently clawing itself out.

    Episode 36: 2008: First Love, Finally! 
  • Ora keeps her promise to kill Yuko, right after Woz defeated her and she is exhausted, injured and defenseless in Sougo's arms.
  • Swartz convinced everyone to work together against Kamen Rider Ginga to get his hands on the alien's power. Considering that Ginga mopped the floor with Trinity and was only defeated with everyone's collective effort, it's disconcerting to think what would happen if Swartz had managed to keep its power to himself.

    Episode 37: 2006: Next Level Kabuto 
  • The Worms reappear, in all their shapeshifting glory, on a rain of meteors, to boot. And it's implied this happened because reality is distorting for some reason that noone knows yet.
  • When Tsukuyomi uses her time powers, she has a brief memory of herself, smiling, in some random room with other people behind her. She identifies two as her mom and dad, and a third man stands in the back, facing the wall. He's dressed a hell of a lot like Swartz was when he traveled back to find Sougo as a child. He's even wearing the same hat too.
  • When Tsukasa shows up to talk to Tsukuyomi about her past, he opens a portal to a random, ruined street. When she asks where they are, he says it's the year 2058, when she was a child. He starts walking towards a quite menacing storm-like formation in the distance.
  • Geiz is worried about Tsukuyomi because to him it justifiedly looks like if she was making a Deal with the Devil.
  • A giant meteor containing dozens of Worms is about to impact the middle of Tokyo. Scary, right? Well, Zi-O uses FourzeArmor to block it. We're cool, right? WRONG! An even bigger meteor is right behind the last one. The episode ends with Zi-O openly muttering that he has no idea what to do.
  • Sougo has gambled on the fact that he appears as Idiot Hero to Yaguruma and has fooled him enough to think he would just walk in a trap. Instead, he made an effective plan of counterattack with Woz and counted with everything that happened. It's as a scary as any reminder that he is the past self of Oma Zi-O, the tyrant of time. Worse, he has this cold smug expression through most of the time his plan is working out and it completely fits his ruthless side and yet looks so much out of place considering his usual attitude.

    Episode 38: 2019: Kabuto's Choice 
  • Even though he didn't mean too, Geiz almost caused the destruction of the entire world. Kagami having been captured, is held ransom for the Fourze Watch and the Ginga Midridewatch, as without them, the heroes have no means of stopping the meteor from destroying the world. Sougo however had a good plan that would allow them to rescue Kagami while retaining their watches. The problem was that Geiz who was in the middle of confronting Yagurama had to talk out loud over the phone while Yaguruma was directly in front of him. This alerts Yaguruma to the plan who quickly transforms and rushes back with his Super-Speed. While Sougo and Woz manages to save Kagami, it costs them their ride watches. Had it not been for Swartz helping the heroes out for personal reasons, along with Tsukuyomi pulling a last minute Big Damn Heroes moment. The world would have been destroyed. It's terrifying how a few simple words at the wrong place almost destroyed everything.
  • Woz and Tsukasa both openly state that space-time is growing even more distorted, and elements from Kabuto's time period are now intermingling with 2019 so that the Kabuto Riders are around even though the 1999 meteor strike never happened and ZECT never existed. Nobody seems to know what's causing these distortions or how to stop them, and they're getting worse and worse with each passing arc.

    Episode 40: 2017: Grand Climax 

    Episode 41: 2019: World, Reset 
  • Hiryu is back... and now his Another Zi-O form is based on Zi-O II.
  • From the preview, everyone has turned on Sougo for reasons unknown, including Junichiro, Geiz and Woz, with the latter (along with Ora) now calling Hiryu their "overlord". Geiz, in Revive Gouretsu, also attacks Sougo when he is UNTRANSFORMED. Junichiro even tries to stab Sougo, his own nephew. note 
  • The world has shifted to a far darker tone. Everyone of Sougo's allies has either forgotten about him, or abandoned him. Yet despite this, everyone is still driven by in an instinct to kill him, essentially blaming him for everything. The place looks like a war broke some time ago. It's in ruins and mostly abandoned aside from the resistance trying to fight off Another Riders.
  • Geiz comes incredibly close to beheading Sougo after he and Tsukuyomi attack him. Yes, he didn't just try to kill him, he tried to behead him with his weapon.
  • What's worse than an army of Dark Riders? How about an army of immortal Dark Riders? Even though Grand Zi-O and Another Zi-O II can summon Riders to support them, Another Zi-O II's army is essentially immortal. Anytime they are killed within his vicinity, time reverses and they are revived immediately.
  • Pictured above, the way Drive's eyes glow after Ohma Zi-O takes control of the summoned Rider to fight Grand Zi-O is creepy to say the least. In addition to that, Drive's Tridoron beeping noises were distorted in order to hammer home the seriousness of the situation.
  • When Tsukasa takes a picture of Sougo, he's blurred. At first this seems like a Mythology Gag to his past pictures. But notice that the only thing distorted in the picture is Sougo himself. It is possible that in this timeline, Sougo is slowly being erased, Back to the Future style.
  • Grand Zi-O is passively standing when Geiz in Revive Shippu about to launching an attack towards him, not bothering to attack him at all as if he has been pushed to Driven to Suicide after experiencing massive Heroic BSoD.
  • Everything is Swartz's fault as he decided that antagonizing Sougo with Grand Zi-O in a direct manner is too dangerous, so he deliberately screwed with time so things would be like they are now.
  • The reveal that Hiryu is doing all of this just to spite Sougo. While Hiryu had showed himself to be ruthless for his revenge before, here he's doing the same things as Oma Zi-O for no reason but to be petty!

    Episode 42: 2019: Missing World 
  • Sougo tried to reason with Geiz, even released his transformation to convince him. This only motivated Geiz to murder Sougo right there and now before he is overhelmed by the hesitation Zi-O invokes in him. Tsukuyomi thankfully stops Geiz before he goes through with it.
  • Everyone is afraid of Sougo now. The people in the resistance shelter run away from him, including his uncle, which obviously pains him.
  • Swartz captured Daiki, grabbed his head and did something very, very painful to him.
    • It is later revealed that is how the time powers are bestowed. Daiki Kaito now has both the same powers as the Time Jackers and is in possession of White Woz's Future Note.
    • The first thing he does is to take the Grand Zi-O Ridewatch from Sougo. Granted, using it didn't help Sougo whatsover, but it was still his most powerful upgrade.

    Episode 43: 2019: Tsukuyomi ・ Confidential 

    Episode 44: 2019: Aqua Calls 
  • One of Sougo's classmates from the very first episode has disappeared on camera, consumed by an orb that looks like it is made of a liquid, leaving nothing behind.
  • The appearance of Another Decade. Unlike the previous hosts, the guy behind it is Swartz, who's obtained not just Tsukasa's powers as Decade, but also Tsukuyomi's. There's also the implication that Another Decade is based around Violent Emotion, the form Tsukasa used when he took down all the Kamen Riders up to W — perfectly embodying Tsukasa's role as "A Destroyer of Worlds."
  • If Heure failed to stop Another Drive's time, he would have ended up with his head crushed like watermelon in pressure test. Worse, Another Drive is Ora. She has reasons to kill Heure and even lured him away from the riders, so she could do it unopposed. And he still cares about her.
  • Michal implies that the presence of Geiz and Tsukuyomi moves the timeline towards the future of Ohma Zi-o instead of preventing it. Tsukasa has his own suggest stating that Sougo is the root of the time distortion and Swartz has used it to his advantage.
  • Tsukasa says that with all the distortions, he'll have to destroy the World of Zi-O, and when Tsukuyomi says that he lost his powers, Tsukasa takes it as a minor nuisance. This raises the decade-old question; what the fuck is Tsukasa Kadoya, and what exactly is the power of Decade?

    Episode 45: 2019: Eternal Party 
  • Ora murdering Heure. It's not only disturbing because Ora murdered a child but this episode shows that Ora does actually care for Heure, even trying to rescue him from Another Drive despite losing her powers. But due to Another Drive nearly murdering her and mocking her powerlessness, she murdered Heure for his powers. In the end, Ora cares more for herself and her safety than anyone else.
  • Another Drive learns it the hard way after laughing off Heure's tragic fate from being killed by Ora. Sougo rarely puts away his cheeky smile, and the only times Sougo had went Unstoppable Rage were whenever he met his future self. Then, misfortunes keep piling on him throughout the course of the episode. When Another Drive begins relishing Heure's death, Sougo finally snaps and gives a brutal No-Holds-Barred Beatdown that harkens as far back as Kuuga when the All-Loving Hero Kuuga snaps. Sougo is an overall nice person, but push him too far and you won't like the result, giving us the reminder that he absolutely is the younger-self of Oma Zi-O.
    • Keen listeners will note a very specific detail about this scene; the very poignant lack of henshin sound effects. There's no "Grand Zi-O!" or "Rider Time!", only the sound of the Ziku Driver chiming, almost like a death bell before Sougo appears in the next shot in his Grand form and decks Another Drive.
  • Swartz's Another Decade ability of putting others in what Tsukasa calls an Another World where the victim potentially experience scenarios of what might have happened, in Owada's case being him winning a video game tournament to represent Japan in the world championship instead of losing in real life. Unfortunately, that's all they experience and, not only does it endlessly repeat, but the victim doesn't even know it's on a loop. And unfortunately for Sougo, there's nothing he can do about saving them until he deals with Swartz so the victim stays in that until something happens.
  • Tsukasa reveals that Swartz is using the Another Worlds to revive the Dark Riders; if they had won in their fights which creates plenty of Fridge Horror of the Another Worlds they come from.

    Episode 46: 2019: Operation Woz 
  • Even without the power that Tsukuyomi took back, Swartz is ridiculously overpowered as he proves by casually murdering Michal and Ora and treating their attempts to off him as mild annoyance. Ora stroke up a deal with Swartz so she could backstab him later on. He predicted it and killed her brutally and effortlessly when she tried. Of note is the method by which Swartz kills Ora: a simple roundhouse kick to the head that's hard enough to audibly snap her neck. The super strength of Riders and their villains is often downplayed in practice so that someone assaulted by a monster gets away with only cuts and bruises, when in reality one casual punch or kick from someone like Another Decade would easily be enough to kill a man.
  • Back in #21, White Woz mentioned his future is a everlasting peace, as if time itself has stopped. Then comes this episode where he mentions the Another World is a place where time stands still eternally. The very implication that Dark Riders in the Another World are eternally reliving their last moments over and over is quite unsettling.

    Episode 47: 2019: Vanishing Watches 
  • Daiki uses the Zi-O II Anotherwatch to revive Tsukasa and suffers from the unfortunate side effect of being forcibly turned into Another Zi-O II. Then he tries to murder Tsukasa, prompting him to simply note that not even Daiki can overcome the corruption of Anotherwatch.
  • Throughout the episode the Ridewatches start to break and with it the world of that Rider merges with Zi-O's world. First the Sky Wall, the Clone Smashes, and the Guardians. Then Roidmudes appear, lead by an Another World Mashin Chaser. Then the Fuuto Tower and Yggdrasill Tower appear, causing Masquerade Dopants and Elementary Inves to appear. Then the Mirror World merges with Earth, causing the sky to be filled with Mirror Monsters. Due to all the Ridewatches breaking Sougo loses the Grand Zi-O watch. Seeing how much reality has been damaged, Tsukasa states he has to destroy the world. All of this is Swartz's endgame come to fruition. He knows that Tsukasa will destroy the world, which will save his own timeline. And the heroes have no choice but to go along with it because they've been strung along since before the first episode.
  • We've never properly seen Decade destroy a world before. It was sort of a vague, semi-visible affair that was handled off-screen at best. Here? We could end up seeing the end of a world live, in-person.
  • The younger Swartz is just... weird. His speech is dull, monotone, and utterly bored. Even as he describes his plans to annihilate all the other worlds, his voice never rises beyond mild amusement, as if the concept of a Time Crash was a bland, first-grader joke. Then, the nanosecond Sougo implies Alpina/Tsukuyomi is better, he freaks out and turns into his older self, barking at them about how he would abandon her in an instant. In a timeline that he fully plans on destroying. Then he blasts the two, and if it hadn't been for Tsukasa Taking the Bullet, Tsukuyomi would've died. He fully intended on killing the older self of his little sister, and had zero remorse about the act. And if Kaito hadn't dropped in, Tsukasa would've suffered the same fate.

    Final: 2019: Apocalypse 
  • Swarz can not only summon the Dark Riders, but even the final enemies the Kamen Riders squared off in their journey. And the two most notable examples? Evolt and N-Daguva-Zeba, arguably two of the most vicious and most dangerous enemies the Kamen Riders have faced off against period!
  • Geiz officially kicks the bucket and dies in Sougo's arms. The end result is Sougo, consumed by anger and grief, turning the Ziku-Driver gold, becoming Oma Zi-O Driver in process. Ladies and gentlemen, the Demon King of Time's coronation has officially started.
    • Geiz's visor shattering as he takes the killing blow meant for Sougo.
  • Woz is so shocked by Sougo's transformation into Ohma Zi-O that he forgets to do an ascension speech until prompted by Sougo.
    Woz: My overlord...?
    Sougo: Woz. Rejoice.
    Woz: What?
    Sougo: I order you to rejoice.
  • Sougo's transformation into Oma Zi-O. Sweet merciful of Iwae, is it both incredibly awesome and terrifying all at the same time! Instead of just pushing the button and then spinning it, all Sougo has to do is just adopt his pose, touch the sides of the driver, which echo like a bell being struck, giving off the impression of a death knell to anyone that hears it. Scarier still, the ground literally breaks apart and is filled with magma, almost like a portal to hell just opened. And that's to say nothing of the announcement his Ziku-Driver, now turned into Oma Zi-O Driver makes. Before, the Ziku-Driver would sing some catchy tune. The Oma Zi-O Driver has none of that, with the voice becoming deep and menacing, not to mention angrily saying "Oma Zi-O" as if reflecting just how truly LIVID Sougo is at this moment. Overall, the transformation into Oma Zi-O is less awesome and awe-inspiring and more terrifying and showcasing that Sougo Tokiwa is no longer an Idiot Hero. At this moment, he is the Demon King of Time. Congratulations, Swartz. You just played yourself.
    Oma Zi-O Driver: Shukufuku no Toki! Saikou! Saizen! Saidai! Saikyou-ou!note  OMA ZI-O!
  • The ensuing Curb-Stomp Battle between present day!Oma Zi-O and the villains Swartz summoned. While it's entirely awesome, there's something eerie and unsettling about the fact Oma Zi-O just utterly trounces whatever's thrown at him. Every single one of the Dark Riders and villains that was called by Another Decade is wiped out in a single shot.
    • Particularly noteworthy were Gamedeus, Evolt, and Daguva, all of whom were notable in being ridiculously hard to kill in their original series- and these are Another World versions which won their climactic bouts. And Oma Zi-O just effortlessly sends them flying and exploding as if they were nothing.
      • Gamedeus was supposed to be beaten by the equally broken Kamen Rider Cronus, and it took the equally invincible Hyper Muteki Ex-Aid to put him in his place. When Gamedeus attempts to attack Oma Zi-O, the Demon King reacts by confining him into a golden sphere, then flings the Bugster away before he explodes into bits.
      • Evolt always managed to split off a piece of himself to ensure that he'd survive in one way or another. And he was always just getting stronger. Granted, he wasn't summoned in Black Hole or his true form, but even his Cobra Form was no pushover for Build Genius, and he seems to be able to use his Black Hole powers anyway. Here, Oma Zi-O obliterates Evolt with a single haymaker punch.
      • N·Daguva·Zeba is arguably a walking apocalypse unto himself. Ultimate Kuuga could only match up against him, and even then, Godai had to maintain focus lest he himself become an apocalypse-level threat himself. During their brawl, you get the feeling he wasn't even trying before Godai managed to fracture his Amadam to force him into his de-powered human form. Also, whenever Kuuga used a finisher on a Grongi, it would trigger a chain reaction that detonated the Amadam fragment in their belt, and the cases of the stronger ones are the cause of the infamously huge explosions from the Rising forms and above. Oma Zi-O kills Daguva with a kick (with the destruction glyph Kuuga's kick imprints on the target) that DOESN'T even cause an city-leveling explosion, meaning he annihilated Daguva without even triggering his Amadam's self-destruct! That's some level of power control there!
  • And his finisher, Ohma Time King Finishing Strike. Not only is it announced with the same deep voice, it's also accompanied by the ominous tolling of church bells in the background, as though it were announcing the end of Swartz.
    Oma Zi-O Driver: Shuuen no toki!note 
  • Keep in mind all of the above occurred happened when Sougo just unlocked the powers of Oma Zi-O. This makes the 2068 incarnation all the more terrifying in hindsight due to that version having FIFTY YEARS to hone and master all of this ludicrous power beyond what this Sougo is capable of. This makes Geiz's decision to go back in time to kill Oma Zi-O all the more understandable and downright sensible: his power has reached the point that there was no other choice left anymore.

Movies and specials

    Kamen Rider Heisei Generations Forever 
  • Everything about Another Kuuga since unlike other Another Riders, Another Kuuga is a giant monstrosity equal in size to a Time Mazine. Its host is also a Time Jacker instead of a civilian and after absorbing Shingo, who's a big fan of Kamen Rider Kuuga, it transformed into its Ultimate Form as pictured above. Even moreso if one knows about the original series. Part of its late-game was about having too much power, potentially making him a Destructive Savior. Kuuga once had to have a portion of the city evacuated by his Friend on the Force before he could use his full power (it looks like the normal rider kick 'til it's time for the Monster of the Week to actually go kaboom... instead of a quick burst of flame it's an ever-expanding firestorm!) Ultimate Kuuga is a form or two after the one that first got him afraid of his own power, and it can potentially end the world. And now that power is under the control of someone who's not overwhelmed into a mindless beast like Another Build, or misguided like Another Fourze - no, the most terrifying power in the franchise's long history is in the hands of a Time Jacker, meaning a truly malevolent figure who would know exactly how to use it, be in full control of it, and have zero compunctions about burning down the entire universe to remake it as he sees fit. We're talking a danger similar to Evolto when he briefly had his full power and could absorb worlds.

    RIDER TIME: Ryuki 
  • The plot of the special has the Rider Battle beginning anew. Which means all the deaths from the Ryuki show are happening all over again.
  • The new user for Kamen Rider Imperer gets eaten alive by a mirror monster.
  • Ishihashi/Kamen Rider Scissors' death. The good news is that he doesn't get Eaten Alive by his own Mirror Monster, unlike his precessor. The bad news is that he gets gruesomely stabbed by Miyuki Tezuka and Jun Shibaura. The way it's presented doesn't help, with many shocked viewers commenting that it wouldn't look out of place for a Kamen Rider Amazons scene.

  • The finale reveals one horrifying prospect. Swartz has regained his memories and resumed his plans. Even worse is the fact that no one is aware of it at all.

    RIDER TIME: Decade vs Zi-O: The Decade Mansion Death Game 
  • The premise. Several people are spirited to a strange house, with anyone who doesn’t go along with the game or fails at a challenge being executed. Highlights include the yakuza man being drained of life by Another Ryuki and the old man being murdered with an axe.
  • As hammy as Swartz' acting in Chapter 2 is, he manages to deliver a chilling last wish:
    Swartz: I'd like... A poisoned dumpling."
  • While Sougo turning out to be a robot may be a funny twist, the reasons for it are anything but. In his universe, humans were wiped out by robots.
  • It's revealed that Misa has been Dead All Along, and that is why she opted to lose the rock, paper and scissors game: she had nothing to lose, after all.

    RIDER TIME: Zi-O vs Decade: The 7 Zi-Os 
  • Imagine this: a group of students stranded in a school in the middle of a wasteland while Inves stalk the surroundings. A few students tries to make their leave and are brutally killed by the Inves, no short of having their insides eaten, torn in half, dismembered. And this is just the first episode!
    • Still in the first episode, we see three students hold a girl hostage because they are hungry. Swartz effortlessly knocks out two of them and the third one tried to jump out of the window, only to break his legs with a sickening crunch and soon be devoured by an Inves.
  • Chapter 2 treats us to a scene where it gives us the impression that Swartz was turning students into meat bits to be fed to other students, the shooting of the scene is straight-out like something from a horror series. It's not students he is cutting apart (which is good), but rather Inves that he somehow captured and killed (which is bad). Justifiable in that it is for their survival.
  • Sougo C turns out to be The Social Darwinist and a self-centered Bitch in Sheep's Clothing who coldly disintegrates his counterpart in broad daylight and in front of Heure (who he used as a hostage to lure out Sougo A.) The sheer disconnect between him and any of the other Sougos in this regard (even the brash Sougo B's pomp is ultimately part of his desire to save his friends), not to mention his willingness to behave like this in an apocalyptic scenario is terrifying in that regard alone coming from the face of what's supposed to be a sweet kid.
    • The next Chapter reveals it is quite the opposite: Sougo C traded places with Sougo A, possibly to drag out who is hunting them. So in truth: Sougo C sacrificed himself, while disguised as Sougo A, giving Sougo A a chance to see who was hunting them.
  • Tsukasa just opens the door to let a bunch of Inves into the school, with no concern over civilians, all because he waged war against the Sougos.
