Headscratchers / Kamen Rider Build

• If it was a shared universe, does that mean the entire W through Ex-Aid takes place in Touto?
  • Seito university hospital. Ex-Aid seemed to takes place in Seito. Though, there's question how did Build manage to get there...
  • The first kanji is different, so not that likely. May be Hand Waved later on, though.
  • Build was shown driving atop the Skywall in the first episode.
  • According to this pic, when the text is translated to English, it reveals that Build's main series is set in an alternate universe, much like Decade.

• How did the Skywall emerge TEN years ago and NOBODY notice?
  • EVERYONE noticed. It's just not mentioned until now. Alternatively, it's an alternate universe. Blame Decade for crossover things.
  • If so, then the shot of the Global Freeze either doesn't make sense, or the people behind the Skywall forgot to pay the bills.
  • Referring to Rider series as existing in the same universe is rather...fluid. The W onwards shows have been linked by movies, but in general if those movies tie into the events of the show or have any links to each other is highly variable. Fourze and Ghost include plot elements from the movies (Ghost even makes the error of having a movie plot idea BE the end game), OOO's movies directly contradict a lot of the events in the show, Ex-Aid's movies seem largely isolated from the series bar True Ending (Mighty Brothers XX having a different origin, no one having heard of Taddle Legacy before etc). Even cameos don't really tie in particularly well (OOO and Build both show up way out of sync with how we see their powers develop in show). I'd argue for marketing and crossovers Toei has this blanket "shared universe", but in series it's probably more accurate to consider it a shared multiverse.
  • Build has been confirmed as an AR World via a description from Heisei Generations Final.

• The name is Skywall. Does it extends through the sky so that even planes can't cross it? It would make transportation so inefficient (they could get to other region by going around the wall or through the sea route) but for all intent and purposes the population are trapped. Which would make crossover a lot more questionable.
  • As aforementioned, Build managed to drive atop the thing on his motorcycle. Based on how his friend didn't seem to suffocate it seems it doesn't pass the atmosphere of the planet.
  • While the physical part of the Skywall fluctuates with its height (as there are parts where you can get on it from ground level no problem), the real issue is the red light emanating from it. It appears to destroy anything that it touches. This crimson barrier can be seen from space, if the scene explaining the three regions is anything to go by. If so, then the "Sky" part originates from this trait.

• How far the sky wall extends out length-wise? Can people get to other parts of Japan by eventually go around the Skywall by going far left or right enough? Or does the Skywall expand so far that it is also cutting through places like China and USA?
  • As shown during exposition in the first episode, the Skywall stretches out from the center of Japan and goes in three separate directions, until they fade out at the sea without reaching any other landmass. As it is, it seems the only way to go from, say, Touto to Hokuto, is to go by the sea.

• So episode 3 shows us that the Skywall isn't perfect, there is at least one small spot where there's a "hole" with no wall AND no red light, allowing people to pass through from one district to another. And yet no one from each of the three government knew about this? Looks like they didn't check the Skywall properly. Or maybe they didn't even bother doing that?
  • They probably knew, but it was a smugglers' route. It is impossible to keep checking on all possible hole (especially if they are located in the sea).
  • It's a small hole, so it's not practical for anything bigger than a small boat, and its useless for large scale, government needs.
  • As shown in #33, there are several complete gaps in the Skywall, but the red light is still emanating from it. It is likely that only those with proper protection, Kamen Riders?, can pass through the red light unharmed. Other than that, others might have to go around the Skywall or through a "hole".

• In episode 3, Sento shows up untransformed in front of the Guardians and started shooting them. Is that even safe, considering he works for the same government as the Guardians? Sure he blew all of them up, but if any of them send a live footage to their boss before being blown up.....
  • And even if he works with the same government, his job isn't about the Guardians, it's about analyzing the Pandora Box. He shouldn't even gets a chance or permission to analyze the Guardians and find out their inner working, since it's not his job.....
  • While both seem like just the usual Toku plot convenience, the series actually does provide an explanation for how Sento gets away with being so sloppy about his identity: it wasn't ever really a secret. Faust knew who he was the entire time and just played dumb because him running around was monitored and guided by one of their agents the whole time. Episode 14 clearly spells it out: he was allowed to "play hero" and poke around technology he shouldn't have access to because it benefited the enemy to make more Fullbottles and develop new technology for the Rider System.

• Did no one notice the bottle caps has a letter indicating the best match? No one?
  • To be fair all they have is the first letter and they don't know what each one is called until it's purified for use.
    • Except each letter also has a background color that hints at what they are. For example, T with an orange background can't be Tank, since Tank is blue. G with a silver background can't be Gorilla, since Gorilla is brown.
    • I think that in the show, the caps of the bottles only have the letter that represents itself. That it is only when the best match is found, that both letters appear.
    • Very sure some close up scenes shows that the bottles already have both letters on the cap since way before their Best Match is found.

• Also, regarding the best match, can't it just be tried by using a brute force (trying all possible combinations)? It isn't that many.
  • A possible explanation is Sento isn't looking to find the best match, he is looking to find 'how the best match works'.
    • No, he definitely is trying to find the Best Match, that's the entire reason for the funny scene with Taka & Gatling bottles in episode 3.
    • Any of you ever hear the phrase "miss the forest for the trees"? Basically Sento is focusing so hard on why and how it works, he has completely missed the fact that it doesn't have to be as complex as he believes it to be. He's made up his mind that it must be this complex problem, and thus he has to use an equally complex solution.
  • Huh? Isn't that's what he's doing? Trying all possible combinations?
    • Not the OP, but I think they meant just taking ten minutes and sticking every possible combination that he has access to at the moment into the panel. And to be fair, this argument has merit, as he surely would have discovered the Lion/Cleaner match if he had, but as for now he doesn't even realize it's available, since Episode 2, no less. But as stated above, that is apparently too simple a solution for Sento.
    • OP here, that's what I meant. Though given that Sento didn't seem surprised at Lion/Cleaner best match, it's possible he had in fact find it earlier.
    • Toyline contrivance, don't think about it.

• Night Rogue's transformation had no stealth point at all. What with it yelling 'FIRE' along with shooting fireworks? Who made this thing? Do they made it just because Rule of Cool? I had a funny thought that Katsuragi or Gentoku purposefully making it shooting fireworks just because it looks cool. Then again, Gentoku seemed... excited when he demonstrated the transformation.
  • I wager they never expected to transform around targets. And frankly, if the armor of the guy that I'm about to fight shoots off fireworks before we begin, then i'm going to be worried it's celebrating my beating.
  • Night Rogue isn't built for stealth despite the name and bat theme. He's more for intimidation than anything.

• So... where does Sento keeps all the fullbottles? Hammerspace? I wouldn't be surprised if he does have one in his pocket.
  • Maybe his coat is lined with loops to hold all his bottles? Or perhaps a system like the Gokaiger, or Kyurangers have that beams bottles to him?
  • He has a belt holder for some of them sort of like Emu had one on the Kimewaza Slot Holder.
  • That holds three. Where did he keep the other thirteen is what we're discussing.
  • The same place most other Riders keep their gadgets; up their asses. Just remember the MST3K Mantra.
  • It looks like Sento's jacket is where he stores Rabbit Tank Sparkling, so... pockets it is.
  • It's about as logical as any of the other Riders who carry around power-up trinkets that logically should be too numerous or bulky to carry on their person.

• So... Kouta appears again, yet, it's been confirmed he's in Sento's world. How he got there isn't the question. Why he's there is the question.
  • Vacation? Even Gods need a day off y'know.
  • Or he could be catching up with his friends still on Earth but took a wrong turn on the way
  • Heisei Generation FINAL? He sensed the villains' threat and gone over to help out.

• Rider system were meant for military application. Whose idea is that making flashy form is a good idea? Ninja + Comic? Lock + Dragon? Pirate + Train? It seemed like a child imagination. Not to mention the belt screaming the attack such as 'Vortex finish! Yeah!'. I have no idea why the government would approve of this.
  • They probably don't care about the style, so much as the substance in this case. That it works is likely as far as they actually care.
  • Katsuragi probably made it all flashy as a sort of 'prototype'. The mass-produced military version might've been less flashy. and the Full Bottle combinations can't really be controlled by anyone. They are what they are. You can't change the fact that iron reacts with oxygen, and it looks like you can't really change what Bottles react with what other Bottles.
    • Alternatively, he made it flashy to make the plans look less conspicuous - if you're someone who stumbles upon a set of plans, you're probably not going to be that suspicious of them if they have modes that you need items with names like "Pirate" or "Hedgehog" as opposed to modes that need items with names like "Machine Gun" or "Artillery" - with the exception of the Gatling and Tank Fullbottles, all of them are named after things that you wouldn't normally associate with military use^note and even Tank could partially qualify for this, since tank can also mean a water carrier - which is, in fact, why they're called tanks; the British named them as such to trick the Germans into thinking they were water carriers during World War I.
  • Also, like Smash, we're not really sure if they can control or modify the rider's appearance. Guess they might as well have fun with it by adding bells and whistles at this point. Alternatively Takumi Katsuragi might be a similiar Ryoma Sengoku indulging type.
    • Given the reveal, it seems Katsuragi is indeed indulging on himself.
  • Episode #41 finally gives answer as to where best match comes from.

• Where the flip did Sento get another Build Driver? Did he make another one with Katsuragi's plans? Was it in the storage locker with the Bottles and Pandora's Box?
  • I'll wager he built a second one, seeing as he has the Project Build data. Exactly as Stalk planned.
  • Given Sento's actual identity, it's very likely he did build a second one.

• A trailer for Heisei Generations Final mentions that 'in 24 hours, the world will be destroyed'. Which world? Sento's world or the main Kamen Rider world?
  • Yes.
  • From the looks of it, both. The preview played during Episode 13's opening showed two towers reaching across portals to each other, and two different Earths were in each one. It seems the villain's plan is to make the two dimensions collide and blow up.

• Nearly all the best match were found within the time span of the show (with some exception like RabbitTank, GorillaDiamond and perhaps LionCleaner). Just what did Sento do within a year he had becoming Build?
  • Seemingly developing equipment, the bottle purifier, and gathering however many bottles he did. Given Stalk's identity it can be assumed they only sent out Smash sparingly until he was comfortable as Build, and able to properly fight and test the System.
    • It could also be that it's possible for some full bottles to be duds - after all, assuming that Build was actually fighting smash all that time, he would've had more full bottles than we saw him have at the start.
    • Remember that until the bottle purifier was up and running, Mishra could only do one every so often. It might be that it took him a while to get it running and Soichi was content to wait.

• How did Sento managed to get Kasumi's letter? Did he forge it?
  • That seems to be the implication - after all, consider that prior to episode 2, Sento didn't really know about Kasumi, and it's entirely possible that Ryuga isn't familiar with her handwriting.
• Why Faust need the Build Driver so much? Can´t they mass produce the Transteam system?
  • They might not know how to build Transteam guns. It's possible that the system might blow up if they disassemble it, and the Transteam system locks whoever uses it at their specific Hazard Level. The Rider System allows a user to keep growing in strength. An army that grows stronger every time they fight is too good to pass up. The Transteam system is specifically designed to be surpassed by the Rider system to begin with, so it's best to have both. There's also the fact that the only people with the Rider system want Faust dead and gone.
  • The Build Driver won't even solve it - the issue is they can't mass-produce Fullbottles. Episode 15 explains that Faust has been leading Sento along towards finishing the Sclash Driver and Sclashjellies - which seem to be mass-produce-able.
    • This is true. Apparently as long as you have a Full Bottle, you can make multiple Sclashjellies of the same model. Cross-Z Charge has both the Dragon Jelly and the Dragon Bottle, and Grease has both his Robot Jelly and respective Bottle.

• So... how did Sento managed to get Octopus and Light Full Bottle? I thought the real one is taken by Stalk?
  • It's likely that those were fakes too. As his transformation broke, he quickly tossed the fakes out to trick Souchi into leaving.

• Sento said that the general public gave him the title of Kamen Rider. With the confirmation Build is in a world separate from the rest of the franchise... how would the general public know what a Kamen Rider is?
  • Build seems to use his motorbike a lot, at least in the early episodes. It's possible people just named him that: they saw a mysterious figure riding a bike, wearing a mask. Thus Kamen Rider.
  • It's implied the Skywall might have been the nail, as the Big Bad duo of the movie are the same guy from the main timeline and his counterpart in the World of Build, meaning some previous Riders might exist in Build's world, at least up to 10 years ago.

• Is Heisei Generation and Build's appearance in Ex-Aid canon? How does Build managed to get Gorilla Diamond prior to the series? Also, Build's appearance in True Ending had the belt saying 'Best Match'. Continuity error?
  • For Gorilla Diamond, the same way he had Smartphone and Wolf, or Rabbit and Tank in his intro videos. Perhaps the former four bottles were improperly purified and only were capable of a handful of uses. For the belt...I got nothing.
  • Perhaps they originally planned Build to be Sento and it takes place during the series. Build in True Ending are saying Sento's catchphrase like 'Let's begin the experiment', 'The law of victory had been decided', 'Build up' aside from saying the same lines as Katsuragi. However the idea doesn't work with the timeline and ended up scrapped.
  • Build in Ex-Aid (the one who met Genm), also has his belt saying Best Match despite the Build using Katsuragi's signature phrases and is heavily implied to be Katsuragi and not Sento. Which messes with the timeline as well.
  • Plot elements of Build may not have been written at the time of those being made.
  • #23 confirmed that Heisei Generation Final is canon, making this weirder.
  • #34 showed that Katsuragi did have the Gorilla FullBottle before, but because of Evolt it's essence faded and he is forced to recreate it as Sento and the Best Match sound is just for merchandise reasons.

• What's with Eraser Full Bottle? What does it do? Erasing Hokuto's team and they suddenly teleported somewhere or what?
  • Hmm...maybe it makes you temporarily invisible by "erasing" your form? At least until the user de-transforms.

• If Takumi knew that the Hazard Trigger would be dangerous, and even his own tech realizes 'bad idea' (since the Build Driver says 'Yabei' which means 'Oh no!'), why did he build it? Blood Stark said that Takumi was the one who built it, so... why?
  • Maybe he only found it to be dangerous after being tested? It gives off nasty vibe given the rumor about Takumi and his 'human experimentation'.
  • Makes you wonder why he hadn't tried to destroy it after discovering how potentially dangerous it is unless he didn't have time to do so or destroying it will cause a big explosion or something.
    • Given what happened to him, it's rather likely that wanting it destroyed was part of what prompted Stark and Rogue to usurp him.
  • #27 pointed this out. It seems that Katsuragi indulged more on his mad scientist side rather than caring about safety.
  • It could be that Katsuragi's plan was to kill Stalk and Ryuga first, then destroy the Hazard Trigger - after all, Ryuga didn't have any powers to speak of when he showed up on the scene, and since Stalk had the Hazard Trigger, it could be that Katsuragi was going to use his regular form to kill Ryuga, and the Hazard Trigger was his back-up against Stalk - he just didn't anticipate Stalk having the ability to remove the essence from his bottles...
  • Because it was intended for creating Last Pandora Panel White, so he kept it.

• Since Sento is the REAL creator behind the Drivers, couldn't he just make a Sclash Driver or a device more powerful than the Sclash Drivers?
  • Yes he could make a stronger device, but I think he and Ryuga were more focused on defending the Touto FullBottles from Grease and the Hokuto Three Crows. Also, this is Kamen Rider, and he will probably make a new device for next month.
  • At least one character notes that Sento seems to prioritize versatility over pure power, which seems to reflect on his choice of driver. Sure, he could go with the stronger Sclash Driver after it was completed, but it has a number of drawbacks and can only use one Jelly (or Bottle) at a time. The Build Driver lets him use two Full Bottles at base, which allows him to use the Best Match pairs to maximize the potential of the Bottles, and is modular enough to allow him to create attachments that could augment its normally limited power, unlike the mostly-static Sclash Driver. It seems that the Sclash Driver, while powerful, just has a lot less room to grow than the more reliable Build Driver.

• There is a Smartphone Fullbottle and a Bike Fullbottle that could have been compatible to turn Kamen Rider Build's phone into a motorcycle, but of all the Fullbottles, it's the Lion that activate the transformation. What powers does the lion have?
  • It probably doesn't actually matter which bottle you put in. Sento just uses Lion because it's the one that comes with the toy of the Build Phone.
    • Hell, it doesn't even need a Fullbottle to transform into a bike.
  • Perhaps the idea is that riding a lion into battle is cool?
  • Mythology Gag to Kamen Rider OOO. The Ride Vendor had a Super Mode of sorts that was only available when Eiji used LaToraTa and the Lion Candroid.

• What's with the mad scientist and their weird sense? 'Funky' seemed killed a lot of seriousness. And Fragile sticker?
  • "Well in my defense, it doesn't say sane scientist on my business card..."
  • The "Fragile Sticker" is probably related to why it's the "Crocodile Cracked Full Bottle". The name suggests that in order to get more power out of it they've de-stabilized it in some fashion and it's become more volatile.
    • The Bottle itself says "Danger" when it's activated, so it being more dangerous for the sake of gaining more power is likely a safe bet.
    • It might also be a reference to how Gentoku's mind has become fragile due to his torture. They put that on as a subtle indication of his insanity.
  • Maybe that's where the detonation chip is implanted.

• It's understandable that F1 Fullbottle might have been scrapped due to "F1" seemingly is a trademarked name, but why Gold-Scorpion Best Match gets scrapped as well? It's definitely not a trademark issue.....so what happened?
  • Best guess is that it's delayed for a Movie War or something.
  • There were some rumors of production issues in making the suit, and they probably didn't know how to make 'gold' into a functioning power.
    • There's a new rumor that the F1 Fullbottle might finally gets released alongside the Police Fullbottle as Ganbarizing prize, possibly hinting that they finally gets the trademark issue sorted out, assuming that was the issue in the first place. But again, this is only a rumor at the moment.

• For all of the jokes about Cross-Z (Charge) not being able to fly... why didn't anybody just hand him the Rocket Full Bottle? That's capable of flying.
  • Rule of Funny?
  • He did. He used the Taka bottle to chase after Grease one time. He detransformed in mid-air as he was at his limits.

• How does Kazumi's friends managed to get to Touto from Hokuto so easily?
  • One of the guy from the Televi-Kun special who probably knew a way was with them. Perhaps Skywall didn't restructure all the way and the hole that leads to Hokuto remained.

• But seriously, shouldn't Sento has been suspicious that a random samaritan cafe owner just so happens to have weapons that can combat Smash and a daughter that can purify the Smash's power? Also, why the heck did Misora kept her vision of Mars' destruction a secret all these times?
  • After losing pretty much all his memories, Sento could probably believe pretty much anything at that point. Also, Misora might have only seen her vision of Mars' destruction not too long ago and with how the gang has to deal with all the war and stuff, Misora telling them about her vision might only make them feel worse.

• So it turned out that the Evol Driver was being used as the power source of the bottle purification chamber at the cafe all along. How did Soichi not find it in all the time he was there?
  • Sento has to remove multiple components and at least one panel to reveal the Driver within the chamber, and since it was his machine presumably he was the only one to do maintenance work where he'd be in a position to see the Evol Driver, hence recognising it. On top of that, given what we know of Evolt's personality, Soichi probably never even imagined that Katsuragi would use the Evol Driver, powerful as it is, as a fancy battery.
  • Nevermind the fact that he needed the machine for a loooong time to make bottles. He wouldn't have done anything to jeopardize it, and likely that's what Takumi was counting on.
  • We also can't forget that the Evol Driver was broken into two pieces for most of the series. He needed someone as brilliant as Katsuragi to repair the thing. If he revealed the Evol Driver as soon as he found it and asked Sento to fix it right then and there, he risks letting a genius get enough information to become suspicious. He already figured out more information than Evolt wanted as Katsuragi, so Evolt decided to wipe his memory and start with a new approach. He played his new role to ensure that Sento, Banjou, and Misora all played their parts in Evolt's scheme because he was careful about what they learned. If he let them get too much information too soon, (like an alien, super-powerful Driver) they'd all rebel and ruin any hope of him securing the prize. Sure, he'd like to have the Evol Driver back, but it's only part of his plans. If it can help him run a more long term set of goals as is, then it's better to be patient and leave it as just a fancy battery for now. When his plans reach his endgame and his puppets only have one more step to take in his scheme, he decides to make his move for his Driver after securing proper leverage.

• Are Soichi and Misora actually biologically related or is one of those you get so attach to someone they basically become family?
  • Well, they had the same last name so either they are biologically related or Soichi legally adopted Misora.
  • #36 implies they are a family ever since Misora was a child.

• So, why did the driver from Mars actually had an Ode to the Joy theme?
  • Rule of Cool? Otherwise Beethoven has some explaining to do to Takeru.
  • It doesn't. It has a discordant, intimidating-yet-regal tune that just happens to match a part of Ode to Joy. At least that's what I'm going with. That or it somehow responds to Evolt's whims much like how it ends attacks with a mocking "Ciao!!"
  • Since the Evol Driver is technically a part of Evolt's Bizarre Alien Biology, it's possible he updated it the moment he slapped it onto himself, also explaining why it uses English, Japanese, and Italian despite being a million-year-old extraterrestrial relic.

• Do they ever explain where did Evolt got his bottles from?
  • For the first two Cobra and Rider, he either had them from Mars, or purified them himself while Sento's dad was alive. For Dragon, he somehow made it upon hijacking Ryuga. Presumably if he does the same to Sento at some point, it will lead to a Rabbit bottle.
  • It is revealed in the latest episode, that Rabbit Bottle is created by Evolt magically pulling the bottle out of Sento's body. His other organic bottles are likely created in the same way, just using different bodies. (His own body for Cobra, and Ryuga's body for Dragon).
    • So if that's the case, does that mean that, were Evolt to possess, oh say, Kazumi or Gentoku, he could pull a Robot or Crocodile bottle from them?
    • The Fullbottle he make is most likely based on whatever essence is most compatible with the host body, so, I guess. That said, in the cases we've seen, he only gets the organic bottle from the victim while the inorganic bottle he uses is always the Rider System itself, so it's unclear if he'd be able to use, say, Evol Robot or Evol Tank assuming he follows the same rules that Sento's Build Driver does.

• One thing I never understood is why there is only one of any given Fullbottle at any given time. The Bottles aren't some form of magical item, they're just containers of purified Nebula Gas. Faust has shown that they can easily create duplicates of the same Smash and the various Sclashjellies or other derivatives of a specific Bottle prove that the essence isn't necessarily all that difficult to replicate from the Sky Wall. So why is it that losing the Bottles is treated as such a great loss? For that matter, why are they an integral part of the Pandora Box to the point where its panels are designed to hold them specifically despite their seemingly random contents?
  • Given the reveal about Pandora's Box, it seems that the limit is while they've been able to mass produce the Full Bottles that turn one into a Smash, they haven't been able to mass-produce the ones that are compatible with the Build Driver^note if that was the case, then it would be the Build Driver, not the Full Bottles, that Gentoku would've gone after while he was Night Rogue; the only Fullbottles that seems to be truly manmade are the "powerup" ones^note Rabbit Tank Sparkling, Full Full Rabbit Tank, Dragon Magma, and technically the Genius Fullbottle and the Crocodile Crack Fullbottle.

• If Sento's Build Driver is the basis for the Rider System of the series, why is he the only one who uses mix-and-match style forms while everyone else only ever uses one Bottle/Jelly at a time? It's been noted in-show that the versatility of Sento's method grants him a great advantage over the other Riders and Rider-like characters and it allows him to make use of the Best Match system that the Full Bottles seem to operate under for additional power. Evolt doesn't really count as his forms are all an organic bottle mixed with the Rider System itself as an enhancement.
  • Regarding jellies: The Sclash Driver doesn't seem to be able to use more than one Sclash Jelly, and considering Ryuga is shown having difficulty from using 1 full bottle at first, it could be that the strain of using 2 would be too much to handle.
  • Also, don't forget that for all of the Build Driver's versatility, it still confers the weakest powers of any transformation device since it pulls a smaller amount of power off of the two bottles, hence the need for powerup items. The other drivers draw out more power from their single bottle/jelly hence they have no need for a second.

• Most of Build's Fullbottle forms have at least one or more powers that they provide him on their own like Rabbit's springs, Tank's treads, Hawk's wings, ect. However, several of the Fullbottle forms Sento uses depend almost entirely on weapons he has to create for them to use separately from the suits themselves like Gatling, Train, Ninja, Comic and Pirate. Since these weapons are made on their own and only themed based on the Best Match, what is it that the forms themselves really bring to the table beyond pure stats?
  • Rule of Cool?
  • I assume that they do possess some sort of ability, but it's either weaker then others, or perhaps they need their match to work, hence Sento creating the weapons to act as a channel. Comic might be able to have small Reality Warper powers, but without Ninja it is possible Build can't use them.
  • Some bottles are required to gain access to their respective weapons. For example, the Gatling fullbottle is needed to summon the Hawk Gatlinger and either of the pirate or Train fullbottles to use the Kaizoku Hassyar.
  • Based on Ganbarizing videos it appears that each Bottle has some power of its own. Gatling, for instance, can generate Gatling guns on any part of the half-body. Densha can create train tracks that he can ride on. Ninja can create various holograms of ninja weaponry, and Comic can create detonating Japanese characters. Assuming Ganbarizing is somewhat accurate (reminder that it's the game where Kurokage can beat Muteki Ex-Aid), then it appears that these powers might exist, but they're so weak that the only way to get mileage out of them is through their weapons. Densha's train tracks are used to guide projectiles, Comic's characters are used to give power to the Ninpotou, Ninja's are used to create and focus the illusions, etc.

• More of a meta question. Why exactly did they introduce Great Cross-Z? It's just a recolor of the already existing suit for Cross-Z, the Cross-Z Dragon and the Dragon Evolbottle. It's also notably just narrowly stronger than Cross-Z Charge, but weaker than Cross-Z Magma. So... what exactly was the point of introducing it?
  • Plot reason: To simultaneously give Ryuga his ability to henshin back, and to give him a much needed upgrade to his base powers. He had to be weaker than Grease at this point. Meta reason: To quote Spaceballs, Merchandising!
    • It was also stated that Cross-Z Magma gave Ryuga discomfort, because of the amount of heat that the form is emitting. This new form is probably just used so that Ryuga doesn't consume too much energy and fight for longer periods of time.

• Episode 37 has a scene in the beginning that looks as if Kazumi's Robot Sclashjelly is destroyed, or his Driver is. But later on we see him transforming without any issue....what happened in the beginning of the episode, then?
  • It's possible it was just the material inside the jelly leaking out due to him getting hit right in the Driver area. The Driver endured the hit (somehow) but the Sclashjelly just was forced to squeeze out more than what could fit in, so it leaked. Also Rule of Drama
  • That's the Variable Jelly that makes up Grease's suit, the very same black liquid we see whenever he transform.

• Looking back at scenes with Soichi, when was he in control and when was Evolt in control?
  • He probably never truly was in control and Evolt was only pretending to be Soichi by emulating his personality and emotions. If Soichi did have control, he would probably immediately tell everyone everything he knows about Evolt.

• Had Gentoku gone mad by the episode 40? What's the reason for his...costumes? It came out of nowhere.
  • Perhaps it was his original personality before the Skywall incident.
  • Based on the Rogue miniseries, he was definitely eccentric before the Skywall Episode, which when added with the PTSD and trauma he's gone through, resulted in the crazy person you see in ep 40 and 41.
    • It actually makes a lot more sense if you think about the chair he used to sit on as Night Rogue.

• How did Nariaki survive his gunshot wound from episode 12? And why is he so out of character in all appearances after that. The show doesn't properly explain this, oh it tries to make us think it explained it, with that whole Gentoku killed Nariaki's dreams, which is just nonsensical, and doesn't explain anything. Also how can he use the spare Evol Driver if he's only human, and not also a part of Evolt?
  • In order:
    1. As a Namba Child, he likely had some form of tracker on him that allowed them to find him in time.
    2. Remember Eiji from OOO? When someone experiences either A) severe trauma, or B) great suffering, they can indeed lose a part of themselves. He had a brief window that he could escape his life, and Gentoku took it away. That was the trigger. However, unlike our underwear loving hero, the experience didn't improve him, instead doing the opposite.
    3. Rewatch the scene where he first dons the Driver, he's suddenly infused with Evolt's cells and Nebula Gas to allow him to use it, as well as to increase his Hazard Level. (And probably setting up the whole body double thing, but that's irrelevant to your question.)
  • It's finally given screen time in episode 47, when it's revealed that Nariaki Utsumi was rebuilt as a cyborg.

• That one scene when Sento and Ryuga were climbing up the stairs in #47: Why were they temporally in their rider forms, and while they're at it, why didn't they take the opportunity to use their powers to skip several floors ahead?
  • We saw them fighting on their way up the stairs earlier, so it can be assumed that that's why they were transformed. As for not flying, perhaps using their powers to fly wasn't exactly an option? There doesn't seem to be enough space to fly in that scene.
    • It's also possible that Evolt wouldn't have allowed them to fly. It would've interrupted his 'game', after all. He likely would've devoured another portion of Japan the second one of them took off, as retaliation for breaking the 'rules'. Although why Gentoku didn't just warp them to the top with the Nebula Steam Gun is beyond me.

• So here's something I noticed during Episode 48. When they were merging the two worlds together, Sento went from his Genius Form down to his TankTank form. Now I can understand losing the Genius form because the FullBottle to make it used a Pandora Box panel, but I thought that since the Hazard Trigger was used in creating the white panel, it would be lost forever during the merging process. What happened?
  • The black panel was created when Evolt placed the Black Hole Trigger in the Pandora Box, but he didn't lose it now did he? So why would they lose the Hazard Trigger when creating the white panel?
    • We never see what happens in the series if Sento tries to use the RR/TT Fullbottle without the Hazard Trigger, so perhaps he can access TankTank without the Hazard Trigger if he jumps straight into the form. Or maybe he modified the fullbottle ahead of time.

• Now with the reveal that the entire season's opening narrations are actually recorded post-season in the new world to complement Sento's memories, how did the voices for characters other than Sento and Ryuga show up? They're the only ones from the old world who got transported into the new world.
  • It's possible that the others do remember the old world later, maybe through Sento's journal jogging their memories (perhaps Misora's deja vu was actually remembering Sento rather than mistaking him for Satou) or something happens in a future crossover to restore their memories. Or, alternatively, Sento gets the journal made into a TV show and somehow gets the others to voice their "characters".
  • According to New World: Cross-Z, the others are actually professional voice actors. As for Evolt, who doesn't have a counterpart, an actor named Tetsuo Kanao (Evolt's Real Life voice actor, naturally) nailed the role uncannily well.

• So the Last battle for Sento against Evolt has him going the upgrades he had. From Rabbit-Rabbit, Tank-Tank, then he goes down to Rabbit Tank Sparkling then to just Regular Rabbit Tank. How exactly did that work? Cause I know that maybe the Full-Full Bottles has the essence of Rabbit-Tank but how did he exactly did he downgrade to Sparkling then eventually the Regular Best Match?

• So um. is there not a version of Takumi Katsuragi in the new world like there is another version of Ryuga running around? Or did Sento literally took his place in the new world also?
  • Considering that a version of Taro Satou exists, it's likely that Takumi Katsuragi has a version of him running around in the new world.
  • He appears in New World: Grease.

• How did new world's Kazumi and Gentoku regain the ability to henshin without Nebula Gas injection? How did they get their gears in the new world?
