The Foundation X plot was left hanging to follow its Film Noir theme. Old mystery works would have many questions unanswered intentionally, and would be bittersweet at best.
Why is the Maximum slot on the right side of Double when most of the time it's for the Joker Memory, a left-sided memory? To discourage Shotaro from pulling a Twin Maximum Drive like he did in "The D Was Seen".
Double (W) becoming Xtreme (X) while fighting the Beast (B) Dopant. The show's theme is called W-B-X.
Actually, according to the Lyrics, It Stands for double(W)-Boilder-eXtreme. The Boilder being the name of Double's rider Machine. still works
W letting go of half itself (i.e., Philip disappearing) after destroying Utopia (U).
Shotaro's favored Memory, Joker, is said to possess the inherent power of the "trump card". Why should this be considered Personality Powers? Shotaro is actually the wild card, being the outlier in both The Chessmasters' plans. What's the wild card in most card games? Joker. Being the metaphorical Joker is what makes Shotaro the trump card, as his sheer determination and devotion tohis friends allowed him to pull off the impossible and shake off the paralyzing fear inflicted upon him by Terror and defeat Utopia single-handedly without transforming, things Shroud's chosen warrior (Ryu) couldn't even do.
This also extends to the movie: Daido assumed that Shotaro was out of the picture without Phillip or Double, only for him to receive the Lost Driver from Sokichi, gain the T2 Joker thanks to his affinity for its powers, and storm the castle in order to rescue his partner and protect his city.
Philip's favored Memory, Cyclone. The two people capable of accessing the Gaia Library are Philip and Wakana. Wakana's signature Memory, Claydoll, represents the power of the earth. The Cyclone Memory represents the exact opposite, namely the power of the sky.
In fact all three of Philip's base Memories can be associated with the sky. Luna obviously represents the Moon, while Heat represents the Sun (compare with Magma, a Memory with similar powers that draws its strength from the heat of the earth).
Xtreme may look like a silly way to spell extreme but it makes sense when you realize that CycloneJokerXtreme is the evolution of Double and X is the letter after W.
It's also a punny name, based off Double's Cyclone Joker finisher, Joker Extreme.
And it goes triple—Xtreme is read in Japanese as Ekusutorimu, which contains the Japanese word for bird (tori), hence the Xtreme Memory's bird shape.
The same logic applies to Accel Booster: B is the letter after A.
Why is the Prism memory in CycloneJokerXtreme's arsenal? Because it allows Double to combine the colorful memories for powerful attacks.
Why is Mick the cat Ryubee's most trusted hitman? Because as a pet, he is totally loyal to his master unlike the rest of the family and Isaka.
Claydoll's Magikarp Power may seem like it came out of nowhere, but it's actually a brilliant use of Meaningful Name. Gaia is the Greek Goddess of Earth. Taken 100% literally, a Clay Doll is a human figure made out of earth. In other words, Claydoll represents the power to make man one with the earth, turning the user into a literal Gaia.
From "L on the Lips", Jimmy's "Spik" singing style tends to be pronounced like "speak", which helps to explain how he still manages to win the judges' respect in round 3 despite the cacophony. Yes: he wasn't singing, he was speaking to them.
Movie Wars Core reveals that Narumi Sokichi was not only a Kamen Rider but had his own heavy equipment like the SkullGarry on hand. Clearly the detective agency's Elaborate Underground Base was built well before Begins Night, and not within the year between that and ep. 1.
Message For Double confirms this, as Shroud did provide Sokichi with said underground base even before he assumed the identity of Skull.
Shotaro taking on Dopant cases alone (especially with Akiko spending more time with Ryu) for the whole year between #48 and #49 seems more likely when you consider that he's using the T2 Joker Memory, already shown to be immune to Memory Breaks.
Except all of the T2 Memories were destroyed at the same time Eternal was.
Actually, only the Eternal memory was shown to break, and that was most likely from having absorbed so much power.
Actually, the T2 Memories have steel-colored tips, while the Joker Memory from the last episode is shown multiple times to have a gold one, confirming it to be the T1.note Yeah, I bet you didn't know you could put a gold tipped Memory in a silver slot.
Not to mention that at the time Eternal was killed for real, he had all the T2 memories active as part of a massive Maximum Drive—an attack that would've destroyed the T2 Eternal memory, would've destroyed all the other memories as well.
Isaka absorbed a huge number of Gaia Memories into his body, something that should be impossible. However, his Weather Memory was apparently used to prevent this (somehow keeping the others in check). All the powers he used were weather-like in nature, so it makes sense. When the Weather Memory finally broke, he was suddenly consumed by Living Connectors. Without the Weather Memory to keep them in check, the Gaia Memories he absorbed killed him.
From Movie Wars Core, the Spider Dopant's special ability caused the victim to inadvertently kill the person they loved the most. A common term for someone who kills their lover is Black Widow.
At first, Kamen Rider Eternal's rather somber, sad theme seems to not fit him very well. Then it's revealed later that he's actually a Fallen Hero with a tragic past, one that the song fits very well.
How come they reuse the Dopant Memories from the beginning of the show in Episode 49 and in one of the spin-offs? Because there's no one to make more Gaia Memories, there's no way to make new ones (since the Sonozaki mansion collapsed onto the area where Gaia Memories are made), and the police began cracking down on Memories some time after the Sonozaki downfall. So you can't have a unique Memory unless you happen to have said Gaia Memory before the crackdown (like the Commander Dopant); find a rare one post-crackdown (like the Energy Dopant); or, if you don't have either one, you would opt for one of the many mass-produced Memories, which happen to be the ones seen in the beginning.
Moreover, unlike most Bifurcated Weapons the Prism Bicker's component parts are completely different from one another. The Prism Sword and Bicker Shield both have their own special abilities, but it's only when they're combined that their true power emerges; just like how Shotaro's and Phillip's different personalities combine to form a Rider that's more than the sum of its parts.
The weapons can even be related to each character:
Shotaro does most of the fighting for the pair, so he gets a warrior's weapon, the Prism Sword, which is always wielded in the right hand.
Phillip's special ability is the reason Double can use two Memories at once, so he gets a weapon which can combine the powers of up to four Memories; the Bicker Shield, which is always held in the left hand.
Another reason is because a Dummy, or a mannequin, usually wears tons of different clothes made for different people. Or to put an old saying, "going a day in someone else's shoes".
The way the episodes are numbered makes for a clever development. The odd numbers start off the case (as in something isn't right) and the even numbers end the case (as in it's now fixed).
Then how do you explain the end being episode 49 and not 50?
See the first Fridge Brilliance entry at the top.
What were those Core Medals doing on the Foundation's databanks if they were sealed inside the Greeed? They were actually the King's Core Medals that were owned by Kougami.
I thought it was weird how the Cyclone Dopant had that huge yellow rider-esque eye. Then when you find out who their relationship with Daidou Katsumi, a.k.a. Kamen Rider Eternal, it makes so much sense! He has his mother's eyes!
It is possible that every single thing done by Shroud was to prepare Philip and Ryu for CycloneAccelXtreme. Philip's body was weak and he did not know how to fight, so he is paired with someone who can fight and look after him (possibly meant to be Sokichi). In theory, CAX runs on rage, and so Fang uses Philip's body and sends him berserk so he can learn to deal with this rage in combat first. Ryu is given Trial to get him used to increased power, and the Engine Blade because he will use a sword as CAX. The Prism Bicker takes up 4 memories, despite Philip and Shotaro having six because out of the normal shape ones they would have 4 between Philip and Ryu. Last, Philip's memories can be considered to match up with the modes of the Engine Blade; Cyclone=Jet, Luna=Electric and Heat=Steam. CAX was not just the latest idea Shroud had. She had been planning for it from when she first met Ryu and hired Sokichi.
As for why she doesn't say FangAccelXtreme is the strongest form of Double, despite the Fang memory being more powerful than the Cyclone memory? As we see in The Movie, the T2 Accel memory doesn't go to Ryu Terui—suggesting that while his synchronization rate with the regular Accel memory might be strong enough for regular FangAccel or CycloneAccelXtreme, it's not strong enough for FangAccelXtreme.
The Cho Den-O Trilogy comprises Episodes Red, Blue and Yellow, starting at the same time that Accel Trial debuted. So Accel, already red, turns blue, referencing two parts of the trilogy—so what about Yellow? Well, Accel in yellow was teased for some time since he turned yellow before going Trial for no real reason (until Double Returns: Accel), which is quite appropriate as Episode Yellow is about Kaito/Diend, who ISN'T EVEN YELLOW, and ends with Kaito going right back to his old ways, with none of the resolution in Red and Blue.
In Double Forever, the T2 Ice Age and Violence Dopants turning out to be Santa-chan and Watcherman respectively makes a funny kind of sense if you think about it - which season is Santa always connected to? The winter. And in the previous movie event, Movie Wars 2010, Watcherman brings up his taste for chicken breast early on, which seems like a throwaway comment...until you notice that Violence Dopant has the most massive pectorals of 'em all.
It's been stated back in Don't Lay A Finger On M that Phillip can gamble effectively to the point where he and Shotaro can clean the house. So how come they're wasting their time with missing pet cases and not gambling? Well, finding missing cats is a really simple task when you have a know-it-all who can just look up where they're at with about three keywords. And it's much safer and moral than gambling is.
The side characters come in pairs: 2 teenage girl informants (Queen and Elizabeth), 2 middle-age guy informants (Watcherman and Santa-chan), 2 antagonist sisters (Wakana and Saeko). One could even count Akiko and Terui and Shroud and Ryubee as pairs.
Going further with this, the two Movie Riders (discounting Joker) are paired as well, as they both serve to be foils for the heroes, or rather, their fulfillment of goals. Narumi's everything Shotaro wanted to be, but with the cost of having to run away from the people he loves, while Daido, brought up in the same manner of Phillip (right down to his mom cribbing notes off how Phillip was revived) had something Phillip wanted (a family in both figurative and literal manners), but treated it more like a toy than anything else.
I thought Terror felt out of place as a Gaia Memory, no matter how powerful it was. And then it hit me, "Terror" sounds a lot like "Terra" when pronounced in Japanese. What's another word for earth? That's right.
Keeping with the theme of pairs, the two Kamen Rider Double Returns movies are essentially two sides of the same coin, or in this case, plot, in which the villain tries to break the hero. One side shows the villain failing (Accel's movie) and the other side shows the villain succeeding (Eternal's movie).
Why is the weapon for the Metal Memory a shaft? Perhaps it has something to do with metal pipes and steel beams used in construction work.
Speaking of which, how did both Shotaro and Philip have the knowledge of doing a Twin Maximum drive, and it's consequences? They tried it before.
Or Shroud warned them at some point... Though why she'd bother to warn Shotaro is anyone's guess.
It's also possible that Philip looked up "Twin Maximum" one time and thought, "Better keep Shotaro from trying this."
In the 11th Delusion Diary, Shotaro imagines the future of the agency in the year 2060. Shotaro and Akiko are old, but Philip hasn't aged. Which is funny until you realize that Philip will stay young forever even as the others around him grow old and die, leaving him alone in the agency. Poor kid.
It's never been stated that Phillip doesn't age. In fact, since he fell into the Gaia Memory well when he was just a little kid, the fact that he's now a teenager should be proof that he does age.
Also, it was a delusion based on Shotaro's imagination. Doesn't make it fact.
Isaka killed off other people to evolve Gaia Memories, which he then absorbed himself. He has dozens of Living Connectors all over him. If each of those is from a Gaia Memory he's absorbed...
It's easy to imagine Ryu becoming just like the Commander Dopant if Philip and Shotaro weren't there for him. On the subject, what in the world was Commander planning to do with his upgraded powers?
Even more easier if he partnered up with Phillip to begin with as Shroud wanted.
This could also count as a Tear Jerker, but it works regardless. Take the Spider Dopant's curse into consideration (in which if you touch the ones you loved, they'll explode) and how Narumi had this curse, even when the Spider Memory is broken. There's a scene in Begin's Night where Narumi slaps Shotaro. Notice how he didn't blow up after that? With this in mind, the conclusion soon becomes clear: Narumi never really loved Shotaro, or at least as much as he loved Akiko.
That or it only works on Akiko.
That's the case- and the Spider Dopant outright says it'll kill the person the victim loves MOST. It makes sense that Soukichi loved his daughter more than anyone else, regardless of how much his protege meant to him.
Ever wonder why you hear a sort of military motif in Stay The Ride Alive, as well as see a bunch of soldiers in the music video? Well, consider how the movie this song was made for dug into more of the event that cost Shotaro's mentor his life. Couple this with Tsukasa's death in his portion, and it makes sense that this gives off vibes of a soldier's funeral.
In "Forever A to Z", all the T2 Drivers seek out the people in the city they're most compatible with. So what does it say about Watcherman that he's singled out by the Violence Memory?
Given that quite a few times he's the victim of slapstick violence during the course of the series, it could be a reflection upon that rather than his own possible violent tendencies.
To prevent the problems of Gaia Memory addiction, the Sonozakis use Memory Drivers to transform into Dopants. This comes with weakening the Dopants powers as well, so they compensate by using the strongest Memories created... Which begs the question of what would happen if the memories were inserted the normal way, thus allowing the memories to show their full untapped power...
This can sort of be seen with Nasca R and Isaka performing experiments on Wakana to try and get her to use Claydoll without the need for the Driver.
Masquerade dopants, the mooks of the season, unlike the next nooks (Waste Yummies, Dustards, Ghouls) ARE human and, unlike most memory users, end up disintegrated when defeated.
