History NightmareFuel / KamenRiderExAid

* Bugsters are basically this year's [[Series/KamenRiderWizard Phantoms]]. Anybody can suddenly come down with a cold or other illness and anything stressful can trigger the transformation into a massive monster before another monster pops out of your body when you turn back to normal. Said monster will then do everything in its power to make your life a living hell just to increase your stress. Soon, you'll start disappearing with the monster growing in strength until it's complete and you disappear from reality. What makes them worse than the Phantoms is the fact that unlike a Gate's inner Phantom, they don't need other Bugster's help to hasten their completion, they can just go and strengthen the stress themselves by making their host sick. You're somewhat safe from the Phantoms if you're not a Gate (unless you're the Gate's source of hope...), but for the Bugsters, you can be infected anytime without even knowing about it. Bugsters don't even have to work on guessing what will stress out their victims either. Graphite confirms that the Bugster and its host are connected in a way that would allow them to know exactly what they need to do in order to complete themselves and kill their hosts.

* Graphite's transformation is nothing short of terrifying due to it coming out of absolutely nowhere, not helped at all by the Bugvisor's positively ''demonic'' [[GutturalGrowler growling]] voice. It gets worse when you consider that the Bugvisor is used to spread the Bugster virus, and that in episode 2 Brave and Ex-Aid both received a direct hit... though that seems to be from the orange cloud it releases. Brave and Ex-Aid just got shot.

* We finally get to see the Bugvisor II in action and it's worse than the first one, [[EvilSoundsDeep with the voice being even deeper]] and [[GutturalGrowler more sinister]]. While the first Bugvisor's voice was meant to sound like a growling zombie, the Bugvisor II's voice sounds calm, cool and collected. It's gone from a rampaging monster to an intelligent and confident villain.

--> You think this series is going to get LighterAndSofter after Series/KamenRiderGhost? Well... you made a fatal mistake. '''GAME OVER.'''

* The trailer shows us Gamedeus in his complete form, and he is absolutely ''terrifying''. There's his BigRedDevil appearance, his screaming '''"[[GratuitousEnglish I AM GOD!!!!!"''']] in a very terrifying voice and the fact it look like he ''killed almost all of the riders when they all teamed up to fight him.'' When Kuroto said that Gamedeus is the ultimate Bugster, he wasn't kidding.

* Saito Yaotome kidnapping Parado. It comes out of nowhere. He is just lazing around on the roof of Seito University Hospital, but then she comes in and sucks him into the Bugvisor.]]

* The trailer shows us Gamedeus in his complete form, and he is absolutely ''terrifying''. There's his BigRedDevil appearance, his screaming "[[GratuitousEnglish I AM GOOOOOD!!!!!"]] in a very terrifying voice and the fact it look like he ''killed almost all of the riders when they all teamed up to fight him.'' When Kuroto said that Gamedeus is the ultimate Bugster, he wasn't kidding.

** The entire scene where Masamune merges with Gamedeus. After he kills Gamedeus, the Level Clear screen pops up with fireworks going off...then he absorbs Gamedeus's data into the Bugvisor and injects it into himself, causing the screen to glitch out and finally crash. This is followed by Masamune going LaughingMad as the fusion happens, ending with the "Game Over" announcement... only [[NothingIsScarier nothing happens]]. Masamune ''doesn't'' vanish... he just raises his head with the TaintedVeins Graphite showed and declares ThatManIsDead, implying the Game Over was indeed true... and what's standing there [[HumanoidAbomination has stopped being Masamune.]]

* We finally got to see how Parado is when he's angry. When the Revol Bugster shoot him in the back while he's having "fun" with Ex-Aids XX L and XX R, Parado is ''pissed''. He proceed to destroy Revol easily while in a extremely unnerving TranquilFury state. Again, he does this against a Bugster who is supposed to be his ally. It's now very clear that Parado is really not right in the head. Whoever it is, if they interrupt his "fun", he will destroy them, whether it's his allies or enemies. Let's also remember that this guy is easily one of the strongest Rider in the series....

** The scariest part about the above is that as Poppy starts to voice that she doesn't want to fight humans, Parado turns around incredibly fast and ''grabs her by the throat'' before pushing her back and holding her by her neck as he pushes her towards the edge of the roof they were conversing on as a ScareChord goes off, in no uncertain terms threatening her to stay the course. It shows the viewer ''exactly'' the [[PsychopathicManchild kind of person]] Parado is.]]

*** Just to clarify, Emu tries to spare Kuroto but Parado decides that the loser needs to have a bad ending. To this end, he takes the Buggle Driver and Dangerous Zombie and uses them to ''pump Kuroto full of the Bugster Virus as he screams in pain and terror and begs for his life''. All Parado does however is smile and calmly tell Kuroto that he'll be taking Kamen Rider Chronicle. Kuroto's last moments are those of absolute ''fucking madness'' as he screams that [[AGodAmI he's God]] and that his ambitions will live forever before he finally gets a "[[NoBodyLeftBehind Game Over]]". '''''Holy shit!'''''

** Nico shows us what happens if you don't have the Compatibility Surgery operation and try to use the Driver... you get the Bugster Virus. ...enough said.

--> Genm Level X: '''Buggle Up! Danger! Danger! (Genocide!) Death the Crisis! Dangerous Zombie! (Zombie Screech)'''

** The whole thing is creepy. Seeing Emu, who was described as a clear crystal just episodes ago, being readily willing to attack and hurt people is just....unsettling.

* Masamune gaining the power to reset time and erase Hyper Muteki, the only Gashat that could defeat him, from existence.]]

-->'''''GAME OVER'''''

* [[OneWingedAngel Super Gamedeus]] is pretty dang terrifying, being a gigantic beast with two dragon-like heads instead of arms and ''freaking covered in eyes''. [[NightmareRetardant However, it loses some of it's menace]] when you realize it's a glorified Bugster Union that can be defeated rather easily by five ''Level 1'' riders.]]

* Kamen Rider Chronicle. We finally have an idea of what it is. It is Kuroto's [[{{Pun}} endgame]] that will transform the ''entire world'' into a literal battlefield where anyone can transform into a Ride-Player and fight forever, with him as the game master. Basically, a horrific mix of ''Series/KamenRiderRyuki'', ''Series/KamenRiderGaim'', ''Franchise/DanganRonpa'', ''Franchise/YuGiOh'', and '''ESPECIALLY''' ''LightNovel/SwordArtOnline''.

* The further showcasing of the return of Kuroto Dan....[[FromBadToWorse as a Bugster]]. CR now has an unpredictablely AxCrazy narcissistic SerialKiller prone to violent outbursts with computerized teleportation powers [[TokenEvilTeammate occupying their workplace]] with only the [[BoxedCrook loosest of safeguards keeping him contained]].

[[caption-width-right:350:'''[[AGodAmI I AM GOOOOOOOOOOD!!]]''']]

* Starting with this one, the updated credits sequence has shocked many a fan, since [[spoiler:Kiriya was practically ''[[{{Unperson}} erased]]'' from the opening. It's particularly jarring to see that the shot of him holding up his gashat is now just a plain background and some static.]]

** Worse? In the four-way Rider fight, Ex-Aid, Snipe and Brave all transform, [[spoiler:with a hologram of Lazer Lv.1 looking on, motionless. It really drives home the fact that his game data might still exist, but the man himself no longer does.]]
* [[spoiler:Using the Mighty Brothers XX Gashat causes Emu to suffer headaches and followed by loss of consciousness for a while. Now, let's look back, almost if not everytime a power up caused a side effect for the Rider, it will ''never'' end well for said Rider.]]
* [[spoiler:The WhamLine delivered at the end by Taiga, "Ex-Aid, you have the Game Disease."]]

** [[spoiler:Nico shows us what happens if you don't have the Compatability Surgery operation and try to use the Driver... you get the Bugster Virus.]] ...enough said.
** [[spoiler:Kamen Rider Para-DX's first appearance and abilities at Level 50, showing just how far the Bugsters still outclasses the Riders.]]
*** Not only that but Kuroto states that [[spoiler:the Gashat Gear Dual is nothing but ''practice'' for Parado in preparation for Kamen Rider Chronicle which is even ''stronger.'']]
** We see why a compatibility surgery is needed to use the Gashats when [[spoiler:Nico tries to use Bang Bang Shooting to eliminate Emu herself, not only does it simply not work for her but it caused a Bugster infection immediately.]]
** [[spoiler:Taiga and Hiiro learn what Kiriya discovered and was [[HeKnowsTooMuch killed for knowing]], Emu is PatientZero for the Bugster Virus. A fact that raises several more alarms:]]
*** [[spoiler:During the flashback when the operation on Emu six years ago failed, the doctors became infected with the Bugster Virus but instead of showing symptoms and disappearing slowly like other patients, ''they disappear on the spot'' with no Bugsters shown spawning. Emu's Game Disease is so virulent that it kills instantly and not even the deaths of several people can cause the Bugster to spawn, imagine how powerful it will be when it finally does.]]
** [[spoiler:Taiga realizes that telling Emu this fact with stress him out severely and can risk causing the virus to become active and warns Hiiro of this, both Riders come to the conclusion that Emu must be eliminated.]]
** [[spoiler:What we previously thought to be side effects of using the Mighty Brothers XX Gashat are now manifesting when Emu uses normal Gashats and possibly in his normal work as a doctor in the form of an "anemic attack", the headaches are not side effects, they're signs of the Game Disease manifesting after stress.]]

* We finally got to see how Parado is when he's [[spoiler:angry. When the Revol Bugster shoot him in the back while he's having "fun" with Ex-Aids XX L and XX R, Parado is ''pissed''. He proceed to destroy Revol easily while in a extremely unnerving TranquilFury state. Again, he does this against a Bugster who is supposed to be his ally. It's now very clear that Parado is really not right in the head. Whoever it is, if they interrupt his "fun", he will destroy them, whether it's his allies or enemies. Let's also remember that this guy is easily one of the strongest Rider in the series....]]

* In after what was a generally fun and lighthearted episode, [[spoiler:ends in Kuroto killing Burgermon, showing how unsafe it is with him and Parado around. And the reasoning behind Kuroto killing Burgermon? [[EvilIsPetty He was from a game Kuroto didn't make.]] It shows that just like Parado, if his allies rub him the wrong way, he'll murder them without a second thought. Unlike Parado however, who at least makes sure the destroyed Bugster's data can still be stored in the Gashacon Bugvisor so it can be use again someday. He chose to go against someone who wasn't willing to fight and posed no threat whatsoever. It didn't further his plans in any way; he just wanted satisfaction from killing an innocent being who just happened to irritate him without doing anything.]]

* The Bugster Virus was created by the [[spoiler:'''[[MillenniumBug Y2K Crisis]]''' and was first discovered by Kuroto.]] Then, on Zero Day, [[spoiler:he ''purposefully infected countless people with the Bugster Virus, killing thousands, and placed the blame on his father.'']] All to create a [[spoiler:monstrous game where people have to fight monsters in real life to survive.]]
** Especially creepy is that [[spoiler:[[UsedToBeASweetKid young Kuroto is not only adorable]], but at that point he seems to have an actually good relationship with his father. Something must have happened to twist that teenager into [[TheSociopath the monster]] who released the virus.]]
* So everybody knows that when Genm got hit by a Critical Finish, he just jerks himself back up? We finally get an explanation for it: [[spoiler:Kuroto has been dying and reviving all this time! Looks like the gashat isn't finished recording death at all after #11. But after this episode, Kuroto has recorded enough of his own deaths to achieve Level X! Now the riders are going to be facing against a true undead Rider.]]

* [[spoiler:Genm showing off his "Level X" powers and wrecking Emu's Gamer Driver at the end of their fight, which is chilling to the core. Nevermind that Emu has a spare Gamer Driver ready in the next episode, but still... Not to mention it ends [[DarkestHour with him taking back the executive chair, proudly telling himself that Kamen Rider Chronicle is almost finished]].]]
* TheReveal that [[spoiler:Emu got infected by the Game Disease by Kuroto. Let that sink in. A little boy in the hospital sent Kuroto ''fan mail'' detailing his idea for a game and some character designs and was rewarded with a game laced with the Bugster Virus that laid dormant in him for ''ten years''. There's ItsAllAboutMe levels of narcissism and then there's just flat out ''psychosis''.]]
** A bit of FridgeHorror might be in play here. [[spoiler:As the young Kuroto [[DrivenByEnvy becomes furious with how good Emu's ideas are]], a familiar static effect appears on-screen. Considering he found the Bugster Virus to begin with, could this be a sign that something really ''did'' happen, [[TheCorruption like being influenced by it]], that led to him becoming the CorruptCorporateExecutive he is now?]]

* Kuroto's [[spoiler:SanitySlippage during the episode. At first he seems okay, approaching the police in an unusually calm manner. Then once he starts fighting, he's moving in an unusually jerky and erratic manner. And once he's lost his immortality, he goes completely off the rails. He infects a large group of people out of anger, and once the riders show up, he's reduced to just going nuts even when he hits the riders, eventually just flailing his arms to try and hurt something.]]
** Also there's the aforementioned [[spoiler:infection of a large group. Kuroto's stumbling around, beaten and bloodied, when he stumbles across a park full of people that he proceeds to infect out of desperation to find the last two required Bugsters. Just imagine being one of those poor unsuspecting people when a maniac starts flailing around a device that's ''spewing a horribly lethal disease indiscriminately'']]
** Also, his [[spoiler:death]]. Like [[spoiler:Kiriya's death]], but worse. And Parado [[SlasherSmile smiles]] through the whole scene, obviously happy with how things turned out.
*** Just to clarify, Emu tries to spare Kuroto [[spoiler:but Parado decides that the loser needs to have a bad ending. To this end he takes the Buggle Driver and Dangerous Zombie and uses them to ''pump Kuroto full of the Bugster Virus as he screams in pain and terror and begs for his life''. All Parado does however is smile and calmly tell Kuroto that he'll be taking Kamen Rider Chronicle. Kuroto's last moments are those of absolute ''fucking madness'' as he screams that [[AGodAmI he's God]] and that his ambitions will live forever before he finally gets a "[[NoBodyLeftBehind Game Over]]". '''''Holy shit!''''']]
--->'''Parado:''' [[spoiler:Thanks for your hard work, [[IronicEcho Game Master]]. I'm taking Kamen Rider Chronicle.]]
*** Making matters worse is the fact that [[spoiler:Dangerous Zombie's strain of the Bugster Virus was strong enough to cripple someone who was immunized against said virus. Kuroto got hit with an extra strong dose of the game disease with no immunity to buffer out the damage dealt and so must've [[CruelAndUnusualDeath died in excruciating pain.]]]]
* So simple, yet somehow so creepy--Parado somehow mucking up the scene's colour saturation when he [[spoiler:tries to talk Emu into killing Kuroto.]]

* [[spoiler:Parado kills six people. All of them were playing Chronicle with no knowledge of what happens when you lose, and they all died on the spot. We get to watch their initial confusion as the deleting effect begins, panic as they learn what's happening to them from "Poppy" (and the Poppy avatar doesn't lose one bit of her bouncy cheerfulness as she tells the doomed players that "Game Over" means you disappear from existence) and finally hear them begging and screaming in terror as they are deleted, including one {{Adorkable}} newbie Emu had watched being given the tutorial near the beginning. All Emu could do is watch as the poor guy faded into nothing, screaming the whole time.]]
** [[spoiler:The music playing when Poppy explains that is just creepy due to it being an up-beat tune slowed down.]]

** Alternatively NightmareRetardant or another level worse: Because CERO's ratings are issued through a playtest in real life, it implies that some game assessor played the game and [[spoiler:used their life as a credit]] just to give the game a rating. It's a bit of a shock that they somehow didn't find any violence, but also likely came down with Bugster shortly after submitting their review.
* And on a more sinister note, the Ride Player activation call is a case of HidingInPlainSight for the Bugster's end goal and how those foolish enough to fall for their trap are riding towards their own extinction.

* Parado's [[OOCIsSeriousBusiness OOC moment]] comes in full circle. [[spoiler:He's ''not'' amused at Emu's reprogramming of Poppy and is even shown threateningly choking her.]]
** The scariest part about the above is that [[spoiler:as Poppy starts to voice that she doesn't want to fight humans, Parado turns around incredibly fast and ''grabs her by the throat'' before pushing her back and holding her by her neck as he pushes her towards the edge of the roof they were conversing on as a ScareChord goes off, in no uncertain terms threatening her to stay the course. It shows the viewer ''exactly'' the [[PsychopathicManchild kind of person]] Parado is.]]

* [[spoiler:Parado's DemonicPossession of Emu and, as of the episode 29 preview, getting access to Level 99.]]

* More of [[spoiler:Parado possessing Emu. Thanks to the excellent acting by both Shouma Kai and Hiroki Iijima, it's just freaking disturbing]].
** On top of that, there's the implication that Parado [[spoiler:has been in control of Ex-Aid Level XX R ''this entire time''.]]
* Parado's evolution into [[spoiler:[[SuperMode Perfect Knock Out Gamer, his Level 99 form]].]] Remember how earlier Taiga and Hiiro were able to match Parado in combat? They're both [[CurbStompBattle effortlessly downed]] by this new form.
* Parado's twisted sense of YouCantFightFate towards Emu. Every time Parado has aided Emu; giving him the Gashat to create Mighty Brothers XX in episode 10, [[spoiler:preventing him from disappearing in Episode 19]] was out of the idea that Emu's fate is his to control so he can have his battle with Emu.
** When you take him seeing Emu as a "friend" into account, it gets rather [[{{Squick}} Squicky]]. You now have a PsychopathicManchild trying to [[InsaneTrollLogic make you happy]] by [[spoiler:[[ManipulativeBastard forcing you to become unhappy so that you'll fight him]]]], all the while wondering [[WhatTheHellHero why you're unhappy with him]]. It paints Parado as an [[BlueAndOrangeMorality incredibly eldritch]] StalkerWithoutACrush.

* A nice dose of ParanoiaFuel: After being kidnapped by Parado, Emu somehow escapes, approaching the gang as they finish a battle. He assures them he is OK, but slips on pronouns, using the confident ''ore'' instead of the more boyish ''boku'' that he usually uses. [[spoiler:It turns out he was being possessed by Parado, who somehow managed to nail his usual mannerism. Were it not for the aforementioned FreudianSlip, nobody would have figured it out. Thinking about everything Parado could have done in Emu's body is just creepy.]]
** [[spoiler:Parado!]]Emu breaking into a psychotic EvilLaugh after [[spoiler:exposing himself]] goes from just plain disturbing to serious NightmareFuel very easily. Kuroto's LargeHam [[ChewingTheScenery tendencies]] and his own evil laugh would become darkly comedic over time (at least to some viewers), but this is more disturbing every time it happens.
* The fact that [[spoiler:both times Parado and Emu fought in their [[SuperMode Level 99 forms]], Parado '''won'''. As close as the second battle may have been, this only spells out bad news for the Doctor Riders]].
* [[spoiler:Had Hiiro, Taiga and Nico not shown up when they did, Emu would've died from decapitation.]]

** With his mastery of time he easily swats the Riders & Bugsters aside as if they were nothing. He even went as far to give Lovelica a PERMANENT "Game Over." Anyone killed by Cronus will ''stay'' dead.

* To show Emu and Asuna how much power he has, [[spoiler:Masamune]] deletes Salty with just a keyboard command. Even worse, Salty was just talking with Parado and Graphite when this happened.
** Also, there was ''no'' real reason [[spoiler:Masamune]] did it. He just wanted to remind the Bugsters he owns them, and poor Salty was a cruel reminder to either follow the rules, or face the consequences.

* [[spoiler:Kiriya]] returns complete and yet is not the same anymore. He sees Emu as a BrokenPedestal [[spoiler:for failing to fulfill his last wish]] and now, willingly works for [[spoiler:Masamune]].
* Gamedeus virus seems to start overhelming Graphite.

** Worst of all, when asked what exactly Kiriya whispered to him, Emu pauses...then solemnly states that YouDoNotWantToKnow. [[spoiler:Even ignoring for a moment that this scene is juxtaposed with Kiriya in the rain, looking at the spot where he was killed...then sporting a SlasherSmile / KubrickStare combo(which itself also counts as NightmareFuel), the fact that Emu is so shaken that he prefers to keep it secret just makes it worse]].

* [[spoiler:The sadistic choice Masamune presents Hiiro with. Kill Emu or lose Saki. He manages to wiggle out of it by targeting Parado, but still, if Masamune wants Emu dead, he won't give up that easily.]]
* The aftermath of Taiga losing a fight against Graphite.[[spoiler:[[DarkerAndEdgier He is so battered and bleeding]] that it looks almost like an early Heisei era series (think rider death in [[Series/KamenRiderRyuki Ryuki]] ). Emu, Kiriya and Poppy are frantically working to stabilize him before ambulance arrives while he writhes in pain. The situation has reduced Nico into panicking wreck as she pleads him not die. Hiiro watches in horror before turning around and running away.]]

** His plan to spoil CR crew's HopeSpot by making Hiiro kill Taiga is just ParanoiaFuel. CR crew wouldn't even know that if he didn't tell, thinking he has Hiiro under control. Their horrified reactions count upon getting to know that count too.

** The very reason that made Emu to do all of these? Nico is infected with Gamedeus' Game Disease, and the Sadistic Choice that Cronus forced Emu to choose.

* Throughout the episode, it's shown that Parado is slowly getting more and more scared of actually dying. Whenever this is shown, it's interspersed with some ''[[SarcasmMode lovely]]'' footage of Parado drowning in an endless ocean. In next episode, Emu says that his and Parado's hearts were connected. That basically means that Emu LITERALLY felt everything he caused Parado to feel, and he CHOOSE to kill him, while feeling like he's the one dying once again. All so that Nico can be saved. Hardcore doctor to the boot.
* In a way, the sadistic choice Masamune gives in this episode to Emu [[spoiler:is to save his patient, or save his creation which he does seem to start to care about lately, as him ignoring Parado's requests of battle usually boils down to "patient first" not "Patient is the only I care about, you get lost monster" like before (optionally, save the current patient, or save the countless patients you could've saved, had you had Ex-Aid's power). It's as if creator of Ju Ju Burger was told to choose between Burgermon and his coworkers.]]
* Poppy's reaction to [[spoiler:watching Emu finish Parado off]]. [[spoiler:She remembers how Emu saved her and Burgermon so seeing him not pick that option with Parado]] is just frightening to her. Exactly the supposed audience reaction. [[spoiler:Sure it wasn't ''permanent'', but she didn't know that.]]

* Masamune gaining the power to [[spoiler:reset time and erase Hyper Muteki, the only Gashat that could defeat him, from existence.]]

* [[spoiler:Creating a cure for the spreading Gamedeus Game Disease, Kuroto gained the ability to cure it which he displays on Kiriya. Fortunately, he didn't show the other side of the ability - infection. Yup, that's right, the resident second worst psychopath now has the strongest strain of the Game Disease at his disposal.]]
* [[spoiler:Worse, the resident absolutely worst psychopath now has too. Masamune Dan saved Gamedeus data after his defeat and injected them into himself, becoming a Bugster. Still worse, Masamune's following smile is the runner up for best SlasherSmile in the history of Kamen Rider. Assuming that ''is'' still Masamune...]]
** The entire scene where [[spoiler:Masamune merges with Gamedeus. After he kills Gamedeus, the Level Clear screen pops up with fireworks going off...then he absorbs Gamedeus's data into the Bugvisor and injects it into himself, causing the screen to glitch out and finally crash. This is followed by Masamune going LaughingMad as the fusion happens, ending with the "Game Over" announcement...only [[NothingIsScarier nothing happens]]. Masamune ''does't'' vanish...he just raises his head with the TaintedVeins Graphite showed and declares ThatManIsDead, implying the Game Over was indeed true...and what's standing there [[HumanoidAbomination has stopped being Masamune.]]]]
---> '''[[spoiler:Gamedeus]] Cronus''': [[spoiler:The human known as Masamune Dan has ceased to exist. [[FusionDance I am an existence with the powers of both Cronus and Gamedeus]]. The overseer of Kamen Rider Chronicle... and the TrueFinalBoss.]]

* [[spoiler:After getting beaten down, Masamune reveals that Gamedeus' strength isn't the only thing he's gained as Gamedeus Cronus. He demonstrates that he's also a living pandemic, infecting countless people and turning them into Bugsters the second that they're infected. The virus can even spread by touch from those infected and cause side effects immediately. Even with all his power, Masamune's still willing to doom countless people to put them under his control. It's just this time, he's doing it all himself.]]
* [[spoiler:[[OneWingedAngel Super Gamedeus]] is pretty dang terrifying, being a gigantic beast with two dragon-like heads instead of arms and ''freaking covered in eyes''. [[NightmareRetardant However, it loses some of it's menace]] when you realize it's a glorified Bugster Union that can be defeated rather easily by five ''Level 1'' riders.]]

* [[spoiler:Masamune, not wanting to receive judgement from the Ministry of Health, decides to commit suicide by stabbing the Kamen Rider Chronicle master Gashat onto his chest. By doing so, green electric volts come shocking at him as Masamune screams in severe pain, then dissolving into green particles, thus also depriving the Riders of the chance to save the Bugster Virus victims.]]

* The Lazer episode is truly terrifying. [[spoiler:Kuroto sneaks into the hospital room where Kiriya is being treated. While Kiriya is unconcious, Kuroto uses the Bakusou Bike Gashat and VR system to torture Kiriya psychologically and threatens him not to reveal Kuroto's identity as Genm.]] Seriously, the episode plays out like a Horror or Thriller movie.

* [[spoiler:Michihiko Zaizen manages to knock Emu out of Rider form and inserts both Mighty Action X and Proto Mighty Action X Gashats into his Driver, making purple cracks appear on his body. This is even scarier for people who watched ''Series/KamenRiderWizard'', as purple cracks on a person is always a bad thing.]]

* The premise may have one for some people. [[spoiler:[[Series/KamenRiderRyuki Takeshi Asakura/Kamen Rider Ouja]] is back to terrorize the Doctor Riders, [[EvilOldFolks even when he's looking surprisingly old]].]]

* And who should be behind Asakura and the Beast Rider Squad? [[spoiler:No, not King Dark. After being absent from the franchise since ''[[Series/{{KamenRiderFourze}} Fourze]]'', '''''Foundation X is back.''''' That is, ''[[ParanoiaFuel if they ever left.]]'']]

* The special has this in the form of [[spoiler:[[Series/KamenRiderBlade Blade]] stabbing Ex-Aid in the gut in a sudden act of apparent betrayal. Yes, you read this right: a veteran protagonist Rider savagely betrays one of his successors. The look on Kenzaki's face is psychotic ecstasy as he sarcastically thanks Emu for bringing hope to the four dead Riders all so that he can break it himself and and have them wallow in despair and tells him that he's playing a game with no continues. It all sounds like how Kuroto would act, right? As it turns out, it's no coincidence - Kuroto has been posing as Kenzaki the entire time. Still, this is a shockingly sadistic performance from Takayuki Tsubaki, Kenzaki's actor.]]

* The miniseries is even worse than the main series in several ways. The Bugster virus is there, but the Doctor Riders, the only people who could stop it, are not. Yet. And the prototype Bang Bang Shooting Gashat, by then presumably the only piece of equipment able to combat the virus with, nearly kills both of its first users. Taiga eventually gets a grip on it, but he still fails to change the situation in any significant way. [[spoiler:And then his best friend gets killed by the Gashat's side effect. Even worse, it happened right in the middle of their fight as Taiga is getting obsessed with the Gashat. And we all already know it won't be the only death Taiga will have to suffer through.]]
* The third part starts with [[spoiler:Asuna finding Taiga repeating 'bugster virus' as MadnessMantra after Maki vanished]].
* It also reveals that [[spoiler:Kuroto infected Saki with heavy dose of Bugster virus while she was in CR, making Graphite manifest into reality. Her death has never been Taiga's or Hiiro's fault and they won't get to know]].

* The end shows Taiga wandering the city, nothing more than a walking corpse now, before [[spoiler:the screen goes into InterfaceScrew, he looks up and sees that his reflection has been replaced by the man who lost everything.]] The scene's horror is nearly palpable even after it cuts into the ''See You Next Game'' screen.
** Just think about Taiga for a moment. He repeatedly states in the main series that he had lost everything; the prequel reveals that this was because of [[spoiler:Genm's]] machinations, turning him from a nice and compassionate doctor into a bitter, aloof, angry shell of his former self as a result. The past wasn't kind to him.

* Taiga attempts to transform in Cronus using Bugvisor Zwei. His previous attempt with the Game Driver looked really bad and really painful, but this one has him ''scream and writhe in pain''.

* [[spoiler:Saito Yaotome kidnapping Parado. It comes out of nowhere. He is just lazing around on the roof of Seito University Hospital, but then she comes in and sucks him into the Bugvisor.]]

* Just Another Parado. He is smug jerkass SocialDarwinist, who makes Parado look like a sweet kid at ''any point of time''. He beats Parado up and [[TheReasonYouSuckSpeech calls him]] a failure for having heart and compassion.

* The further showcasing of the return of Kuroto Dan....[[FromBadToWorse as a Bugster]]. CR now has an unpredictablely AxCrazy narcissistic SerialKiller prone to violent outbursts with computerized teleportation powers [[TokenEvilTeammate occupying their workplace]] with only the [[BoxedCrook the loosest of safeguards keeping him contained]].

** What's worse about Cronus is that unlike Kuroto, whose descent into sanity with his flailing and yelling could be somewhat entertaining to watch, Masamune never raises his voice or moves faster than a calm pace. And why would he need to? All it takes is a push of a button or two, and they're already dead.

* Saki returns... but her data is incomplete and she can only repeats her last words over and over.
