History Trivia / KamenRiderExAid

* IKnewIt:
** Lots of people immediately jumped to the conclusion that Ren was the Bugster from Tokimeki Crisis after he [[spoiler: used his reprogramming powers on Poppy.]]
** There were plenty of fans who thought [[spoiler:Parado was actually part of Emu as an EnemyWithout]].
** Many fans managed to guess [[spoiler: that Masamune Dan was Kamen Rider Cronus and would be the true villain]].
** The fact that [[spoiler:Kuroto will be revived later, because a mad programmer like that must have some kind of contingency plan, and the actor doesn't receive flowers after being seemingly killed on #23.]]
** Since [[spoiler: Kiriya]] was revived without any brainwashing on his part and his whisper to Emu before he was punched was never heard, many fans guessed that [[spoiler: Kiriya hasn't turned evil at all and was letting Emu in on a secret plan.]]

* TheWikiRule: Covered as part of [[http://kamenrider.wikia.com/wiki/ Kamen Rider Wiki]].

* With the exception of the non-canon Dark Decade[[note]][[WhatCouldHaveBeen Who would have been canon]], had ''The Last Story'' not been ScrewedByTheNetwork[[/note]], all riders with "Dark" in their name have appeared in some form of media involving ''Ex-Aid'' - [[Series/KamenRiderKiva Dark Kiva]] appears in the Beast Rider Squad special, and [[Series/KamenRiderGhost Dark Ghost]], [[Series/KamenRiderKabuto Dark Kabuto]], and [[Series/KamenRiderDrive Dark Drive]] all appear in ''Film/KamenRiderXSuperSentaiChouSuperHeroTaisen''. However, with the exception of the aforementioned Dark Drive and Dark Ghost, none of the dark Riders[[note]]as in the villains from the summer movies for Kamen Rider series - i.e., [[Series/KamenRiderDouble Eternal]], [[Series/KamenRiderFaiz Orga]][[/note]], aside from ''Ex-Aid'''s Fuuma, have appeared in media involving ''Ex-Aid''.

* PlayingGertrude: A downplayed version - Hiroyuki Takami, Masamune’s actor, is only 17 years older than Tetsuya Iwanaga, Kuroto’s actor. Meanwhile, Masamune is 25 years older than his son.

** In the original script, Emu is supposed to have [[https://www.facebook.com/bakanki/posts/1624877977552136 a big sister who plays games with him and wants to become an idol despite her fragile body]]. The writer didn’t include that sister because they've noted that she’s a blatant {{Expy}} of [[VideoGame/TheIdolmasterCinderellaGirls Karen Hojo]] from ''Franchise/TheIdolmaster'' franchise, which Yuya Takahashi is a fan of. Incidentally, Emu’s surname sounds exactly like as Karen’s, probably as a tribute to her. Since several plot points regarding Emu's backstory rely on him being an only child (especially in regards to [[spoiler:unconsciously creating Parado out of loneliness]]), the series would probably have taken a very different turn if such a sister had existed.

** [[http://www.animenewsnetwork.com/interest/2017-04-02/updated-new-female-kamen-rider-makes-a-very-pink-debut/.114067 This]] Anime News Network article about the debut of [[spoiler: Poppy as a Kamen Rider]] initially called her the first female Kamen Rider even though there's been multiple female riders a [[Series/KamenRiderRyuki few]] [[Series/KamenRiderHibiki times]] [[Series/KamenRiderGaim before]]. Fortunately, they corrected the article not too long after posting it to clarify that [[spoiler: Poppy]] is the first female rider with her own exclusive transformation device. [[spoiler:At least until Cronus debuts, since he uses the same device]]. Even then, she doesn't count as such, because [[Series/KamenRiderDecade Natsumi Hikari]] is the first female Rider with a unique device [[spoiler: and with Cronus' debut, still holds that unique distinction]]. Yes, she relies on a Kivat like Kiva and his variants, but unlike the latter ones, she doesn't use a belt, just the little bat herself as a trinket, not unlike a MagicalGirl's trinket. Although if one was to exclude movie-exclusive riders, which Natsumi falls in the category of, then [[spoiler: Poppy]] would have held that distinction until [[spoiler: the debut of Chronus]].

** Many fans [[UpToEleven managed to guess]] [[spoiler: that Masamune Dan was Kamen Rider Cronus and would be the true villain]].

** Kamen Rider Cronus' costume seems to be built mostly off of Genm's [[Series/KamenRiderWizard Wizard]] Gamer form (most obviously the BadassLongcoat) with elements of the Ride Player costume. The helmet also appears to be based off Genm’s helmet with the coltish looking like the concept art from Genm Shakariki Spirts.

* RecycledScript: Not exactly same, just similar. In ''Series/KamenRiderOOO'' there was an episode with a [[VictimOfTheWeek genius surgeon]] held back by her father, the director of the hospital she worked at. She was banned from performing operations on anyone and was justifiably angry, which made her a perfect piece in Kazari's next plan. The reason was that her father didn't want her to become surgeon with all the skills, but no compassion and responsibility as he put it. Enter [[TheStoic Hiiro]], another genius surgeon, who treats patients as procedures and has little respect for anyone, who does otherwise. Also, he avoids taking responsibility for risky operations. In his case, it's [[DoctorJerk Taiga]], who brings this up. Ironically enough, Hiiro's father indeed is a hospital director, but too much of a absent minded weirdo to thought anything like this.

* ActorInspiredElement: The CerebusRetcon of Emu's rather morbid backstory in ''Mighty Novel X'' came from Emu's actor (Hiroki Iijima) performing an unnervingly nihilistic-looking DeathGlare during his TranquilFury moments. In context this mainly came off as Emu's BewareTheNiceOnes nature (and, in real life, apparently stems from Iijima often just [[FaceOfAThug having a tendency to have a colder-looking facial expression than he actually does]]), but was noticeable enough that Japanese fans commented on it resembling a [[https://roaring.earth/tibetan-fox/ Tibetan sand fox]], and according to Yuya Takahashi, was apparently what led to the idea of Emu having a lot more of a DarkAndTroubledPast than was suggested in the series.

* Every single episode of ''Kamen Rider Ex-Aid'' and nearly all of its movies were penned by head writer Yuya Takahashi alone with no additional writers helping him, though some did write a few specials that he supervised. Previously, the only made-for-TV ''Kamen Rider'' season to have been written entirely by its [[Creator/ToshikiInoue head writer]] without others was ''Series/KamenRiderFaiz'' (not counting the Amazon Prime series ''Series/KamenRiderAmazons'', which also has every episode written by the [[Creator/YasukoKobayashi head writer]][[note]]Ironically, the only installment she didn't write, the GrandFinale movie, is instead written by Yuya Takahashi under her supervision[[/note]]).

** The fact that [[spoiler:Kuroto will be revived later, because a mad programmer like that must have some kind of contingency plan, and the actor doesn't receive flowers after being seemingly killed on episode 23.]]

** As 2017 is the fifteenth anniversary of ''Series/KamenRiderRyuki'', Takeshi Asakura/Kamen Rider Ouja returned in a special starring Hiiro/Brave, portrayed by his original actor. Furthermore, in ''Chou Super Hero Taisen'', Shuichi Kitaoka/Kamen Rider Zolda will also return as one of the main protagonists alongside later heroes. Not to mention [[spoiler:Parado's Level 99 transformation pose]] is similar to Ryuki's pose when he's about to execute his Final Vent.

** Hiroki Iijima/Emu Hōjō and Toshiki Seto/Hiiro Kagami are fans of ''Kamen Rider Ryuki'', to the point that their favorite riders are Shinji Kido/Ryuki and Takeshi Asakura/Ouja respectively. Seto would even costar with Asakura in ''Kamen Rider Brave: ~Let’s Survive! The Revived Beast Rider Squad~''.
** Shōma Kai/Parado is a massive fanboy for ''Series/KamenRiderKuuga'', which he made abundantly clear in most of his answers during a post-''Ex-Aid'' cast interview.

** The Ghost, Drive and Gaim gamers suits are recolored Ex-Aid level 2 with different helmets and armor.

** The site of the final battle between Cronus and Gamedeus in episode 43 is unmistakably [[Series/KamenRiderGaim Helheim.]]

* ActorAllusion: More of a singer allusion, but the Hyper Muteki Gashat jingle performed by Hironobu Kageyama could easily pass for a ''Series/{{Garo}}'' theme. Also one of its major lines is "Sparking!" One of the closing lines of the first opening of ''Anime/DragonBallZ'', CHA LA HEAD CHA LA, is "Sparking!" and it was also sung by Kageyama.
** The Jet Combat Gashat announcement references Kageyama's performance of the ''Series/ChoujinSentaiJetman'' opening theme.
** Kageyama put so much into just a couple days of recording that he blew out his voice for a bit.
** Mighty Creator VRX has the ability to create weapons out of thin air. The gashat's announcer Creator/JunichiSuwabe had [[VisualNovel/FateStayNight some experience with this before]].
*** He also voiced Lovrica, a dating sim protagonist, [[VisualNovel/FateStayNight just like EMIYA]].
* CastingGag: Tetsuya Iwanaga, who plays Kuroto Dan, is actually a licensed pharmacist in real life. Ironically, the character he plays is one of the few main characters who is ''not'' a doctor, even if he did create the Rider systems. Yet, like the character he plays, he is a genius. Iwanaga is a member of the Japanese branch of Mensa and was once given a rating of Triple-A for the astronaut aptitude test from UsefulNotes/{{JAXA}}. In an interview, he also said studying is his hobby and has acquired a number of licenses and qualifications. So, there's also a case of RealitySubtext here.
** FridgeBrilliance: In the show, his position is more akin to that of the governing board ([[Series/KamenRiderBlade No, not that one]]) of a hospital, which isn't always comprised of doctors.

* DawsonCasting: Inverted. As revealed in the ''Ex-Aid'' character book, Taiga is 29 years old, making him the oldest of the four main heroic riders in ''Ex-Aid''. However, in an inverse of this trope, his actor was 22 years old at the time of the show (he was born in 1994). It's the same with the other actors. Kiriya is 27 years old, while the actor playing him was 23 years old (1993). Emu and Hiiro, who are both 24, are played by actors who were 20 (1996) and 21 (1995) at the time, respectively. There is also an aversion with Kuroto, whose age is the same as his actor (1986), which is 30 years old.

* {{Defictionalization}}: ''Mighty Action X'' was released as a legitimate 3DS game to promote this series. It can be downloaded through a code after purchasing ''All Kamen Rider: Rider Revolution'', provided you have a Japanese Nintendo eShop account (and a Japanese 3DS to boot).

** Inverted with Ren Amagasaki/Lovelica Bugster. Shinya Kote plays Ren in his human form, while Junichi Suwabe voices him in his Bugster form. Suwabe's voice is dubbed over Kote's performance when Ren is using his Bugster abilities in human form.
