History Funny / KamenRiderBuild

* Sawa acting as a CombatCommentator causes Sento to snap at her and tell her to shut up because she keeps throwing him off his game. He even loses steam for a moment when she steals the tail end of one of his [[CatchPhrase Catch Phrases.]]

* Soichi's reaction when he comes down into the lab only to find Sento pounding at the bottle matching wall with a mallet. He doesn't seem to believe his eyes, but pulls himself back together quickly and goes to stop Sento. [[spoiler:It goes into TearJerker soon afterwards as Sento breaks the bottle matching panel out of the wall, [[WhamShot confirming his suspicion]] that it's part of Pandora's Box and that Soichi has been lying to him the whole time.]]

* [[spoiler: The revelation that Sento apparently used to be some sort of ThePigPen [[JapaneseDelinquents delinquent]] ]].

** And then Sento completely deflates, almost sounding defeated at how easily Ryuuga can pick out Best Matches. [[spoiler:His energy comes back twofold however, when he goes into a creative frenzy building a Weapon for [=NininComic=].]]

* Ryuga follows Sento around the lab because of the events of #6, [[spoiler:namely the implication that Sento has killed Katsuragi]]. His (at times bizarre) distrusting scowls are just the cherry on the top.

** After paying [[spoiler:the smuggler to take them across the Sky Road (said smuggler being also over the top with gelled hair and super dark sunglasses he peers over)]], the camera pans to show Ryuga, dressed as a clown, musing on how Misora is "kind of awesome." Sento agrees... Then seems to ''just realize'' what Ryuga is wearing.

* The episode, as usual, starts with a review of the previous episodes… except this time, half of it is Ryuga baiting Sento into talking about his weapon instead of actually describing what happened last episode. Also [[spoiler:Ryuga admitted Katsuragi as a true genius, unlike Sento. This becomes funny after the reveal that Katsuragi is Sento.]]

** On more grimly hilarious note, their assumptions that Touto Goverment creates Smash for military purposes are ''[[RightForTheWrongReasons technically correct]]'' [[spoiler:given that Faust is a rogue faction of Touto's government.]]

* Sento claiming that Utsumi is like a cyborg. In a ''Kamen Rider'' series, this is some serious TemptingFate. [[spoiler:This becomes JokeAndReceive when Utsumi is revealed as a cyborg much later.]]

* [[spoiler:Gentoku's SlasherSmile at everything going according to plan, [[TyrantTakesTheHelm allowing him to take control of Touto]] ''shouldn't'' be funny. However his absurd mustache-twirling and the way the scene's shot makes it seem more hilarious than scary.]]

* When [[spoiler:Sawa]] talks about being a spy for Namba Heavy Industries, everyone ponders about it gloomily... and Ryuga just stuffs his mouth with ramen.
** [[spoiler:Sawa]] also mentions that she knew about Build's identity and his secret base in nascita from the start, and [[spoiler:just bluffed her way in using a book of matches.]] [[SkewedPriorities Both Sento and Soichi are dancing ecstatically upon hearing this,]] because it means [[spoiler:their [[WhatAnIdiot careless mistakes]] from #2]] never happened.

* Misora is pondering if the Namba Heavy Industries forced [[spoiler:Sawa]] to spy on them. The camera then moves to show [[spoiler:Sawa]] chained to a beam in similar way like Ryuuga was in early episodes.
** When [[spoiler:Sawa]] provides exposition, Misora sticks her plushies around the corner to peek at [[spoiler:her]] instead of doing so herself.

* [[spoiler:Sento sees Sawa dangling from a balcony pursued by government men. His reaction is a [[DullSurprise bored]] ''this is the worst''.]]
* Touto Government forces comes to arrest Night Rogue while he is sitting [[SlouchOfVillainy slouched]] in his tacky chair. It gets even better when you realize [[spoiler:[[NotSoAboveItAll it's the normally stoic, serious Utsumi wearing the suit!]]]]

* At the end of the episode, when [[spoiler:Soichi]] takes away all the bottles and the Pandora Box, he used the classic green cloth with white swirls commonly associated with thieves in Japan. As if he needs to make it more obvious he's stealing them away.

* [[spoiler:Gentoku joins Guardians raiding nascita and searches around for Pandora's Box himself. He opens the fridge in dramatic manner and... finds normal groceries. Someone (most likely Sento) clearly thought ahead while they were moving Pandora's Box to keep Gentoku from finding the secret lab.]]

* Gentoku revealing that [[spoiler:Sento is Takumi Katsuragi]] is not funny. The fact that he indulges in infamous slightly unhinged EvilLaugh afterwards on the [[NarmCharm other hand]]…

* Throughout the episode Kazumi behaves as though he knows Misora, hinting that they share a past together. [[spoiler:It turns out that he simply recognizes her as Mii-tan, who he's a ''huge fan'' of, almost like they were trying to remind you that his actor was the goofy [[Series/KamenRiderKiva Otoya]].]]

--> '''[[spoiler:Misora]]:''' (disembodied dialogue) Hi! [[spoiler:(the camera shows Kazumi's Mii-tan wallpaper) It's your idol...]]
--> '''Kazumi:''' [[spoiler:(grins like a dork)]]
--> '''[[spoiler:Misora]]:''' [[spoiler:Mii-tan!]]
--> '''Kazumi:''' [[spoiler:(while mimicking the pose on his wallpaper) It's Mii-tan!]]

* There is something grimly hilarious in Tajimi being a ''very'' SoreLoser. Also, [[spoiler:she screws herself over by focusing everything on Touto and not paying attention to Seito, leading to her country being invaded and ''conquered'' when she wasn't paying attention and to her being detained by Seito's Guardians.]]
** On a similar note [[spoiler:Tajimi is almost hilariously offended at the revelation that Stalk was ''also working for Seito'' and that he'd betrayed her. Considering Stalk's business relationships with Faust, Touto, Sento, and possibly Namba one has to wonder if she honestly thought his loyalties were truly with her or if she just had the worst pattern recognition skills in the world.]]
* The fact that [[spoiler:Kamen Rider Rogue, a character whose design incorporates broken glass patterns, has a ''fragile sticker'' on the back of his head.]]

* During the previous episode recap at the beginning of the episode, Prime Minister Mido butts in to arrogantly declare that Seito will take victory in the second fight of the representative match, only for Sento to confuse him with a long string of nonsense that hilariously enough is an accurate description of [=RabbitTank=] and its connection to the [[spoiler:Full Full [=RabbitTank=] Bottle.]]

* During the battle, Ryuga reminesces about the heart to heart conversation he had with Kazumi earlier. That's good and all, but it turns out that Kazumi's idea of easing the mood was to imply there is something [[{{HoYay}} more]] between Ryuga and Sento. Underlined with him ''eating a [[UnusualEuphemism carrot]]''.

* [[spoiler:[=RabbitRabbit=]'s [[RubberMan stretching]] Rider Kick]] just stops right in front Rogue's face, causing him to flinch into a defensive position before realizing that the kick has stopped just in front of him. His attempt to counter is foiled by the kick building up enough power and snapping Build towards Rogue with enough force to bash him through the solid concrete wall of the arena and ''through another concrete wall outside the building.''

* After Sawa [[spoiler:gives Sento the signal that the Nabeshimas are in the clear, he sighs and gets up as if Rogue didn't just serve him a full course ass-whooping.]]

** [[spoiler:For context, Kazumi agreed to help Sawa with the Nabeshima's family rescue mission on the condition that he will get to have a handshake with Misora, only to find Misora and Ryuga holding hands.]]
* After [[spoiler:Stalk swapped Namba's face into Prime Minister Mido]], he bites into his taiyaki like [[Manga/DeathNote Light with a potato chip.]]

* [[spoiler:Namba]] Mido acts like an conductor of an orchestra in the beginning of the episode and then keeps part of the act ongoing through the episode. When activating part of the Pandora Box, Stalk makes similar gestures.

* [[spoiler:Namba]] Mido tries to make the recap of the episode alongside Sento until he inadvertently reveals a slight hint of his [[spoiler:real identity.]] His excuse? [[spoiler:That he's loyal to Namba Heavy Industries.]] and they shouldn't spoil the episode. Despite the very same scene showing on-screen when he said that, ''is the spoiler itself''.

* As absolutely ''freaking awesome'' as [[spoiler:Cross-Z Magma's debut fight is, it's pretty funny to learn that the steam coming off the suit isn't just a cool effect. The suit is quite literally steaming hot, as Ryuga finds out when he seems to come down off the adrenaline rush of fighting Blood Stalk and starts twitching and stumbling around yelping out things to the effect of "that's hot!"]]
* Sento's reaction to [[spoiler:Cross-Z Magma's henshin]] is literally him acting as if he just remembered the form's name.

* Just think about how the [[spoiler:ArtifactOfDoom and the ability to control it is now in possesion of the franchise's biggest dumbass in 16 years]]. [[note]] That's about the time from [[Series/KamenRiderRyuki Ryuki]]. Shinji Kido being a dumbass is the only thing that the [[TheLancer other]] [[AmoralAttorney three]] [[AxCrazy Riders]] had (and could) ever agreed on.[[/note]]

* Considering how much Sawa and Misora agonized over it and how much the episode preview and the music playing during the scene played it up, [[spoiler:Ryuga learning he's not human is a hilariously casual affair.]]

--> '''Sento''': ''(referring to the research handed to him by Sawa)'' [[spoiler:Hmmm... [[MoodWhiplash Banjo, it says here you're not human]]. ]]

** The funnier part is that even though this matches Mido's usual personality, we know [[spoiler:it's actually not him, but Namba.]]

* What should have been a shocking PlotTwist when Ryuga [[spoiler:is turned into the next vessel for Evolto]] is greatly marred by Ryuga inexplicably developing a FunnyAfro.
** It's likely most of the hairstyle change resulted from [[spoiler:the energy discharge from Evolto and Ryuga's explosive punches]], but... That doesn't explain how his braids came out so seamlessly, or why [[spoiler:Evolto]] has apparently decided to '''keep''' the look in the next episode preview.

* Kazumi's prep talk towards himself to hug and comfort Misora while waiting for [[spoiler:an unconscious Sento to wake up]].
** Not to mention Kazumi nearly putting an arm on Misora's shoulder after much difficulty to comfort her only for it to be ruined by [[spoiler:Sento regaining consciousness]].

* [[spoiler:When Evolto has taken over Sento, he reaches into himself to create a new Evolbottle with Sento's essence and it turns out to be the Rabbit Evolbottle. Evolto actually seems ''disappointed'' that Sento's essence didn't provide him with a Tank Evolbottle.]]

** [[spoiler:Even better, it turns out the Evol Driver toy does in fact have special programming for an Evol Tank form.]]

* Sento narrates the opening narration as usual when Ryuga barges in, [[spoiler:demanding that he prove if he's Evolto or Sento by making a cup of coffee and then ''immediately'' stating he's Evolto because the coffee was awful. Evolto's reaction is quite literally "Oh well, you got me there."]]

* How does Ryuga [[spoiler:get his powers back? You guessed it. Punching something ''[[WhenAllYouHaveIsAHammer really hard.]]'']]

* [[spoiler:Katsuragi's]] "what the hell" reaction to looking at Taro Satou's face in the mirror.
--> '''[[spoiler:Takumi Katsuragi]]:''' ''[[GratuitousEnglish Oh no!]]'' This is my face? How is this even physically possible?
** Misora, Sawa, Ryuga and Kazumi are all kneeling on the ground with their back turned to him, trying to figure out what to do now and casting suspicious over-the-shoulder glances at him every so often. And nobody bothered to tell [[spoiler:Katsuragi]] about how he got Taro Satou's face, even though at this point they all know how it happened.
** They talk about Katsuragi's title of ''Devil Scientist'', which [[spoiler:makes him turn around and sourly note that the ''devil'' part is uncalled for, before casually stating that he was the one who made Misora purify Fullbottles. [[NotHelpingYourCase The same process that would leave her in a coma before Sento made the machine to reduce the strain]].]]
* [[spoiler:Katsuragi]] entered the battle in [=RabbitRabbit=] form. And then proceed to complain that the form is way too advanced for him.

* Evolto laughing evilly when [[spoiler:Utsumi goes off the deep end after Namba kicked the bucket]].
* Utsumi's [[spoiler:evil grin is nowhere near as threatening as the one Gentoku used to have.]] The fact that the [[SoundtrackDissonance cheerful and upbeat "Be The One" is playing while this is happening]] does not help.
* Even better, [[spoiler:Mad Rogue has ''facial hair''. The bat is a ''unibrow'' and the mustache is ''made from an engine!'']] This really ''is'' a [[TitleDrop Mad World]].

* [[spoiler:Even Katsuragi calls Utsumi a cyborg.]]

** The reveal also veers into TearJerker and SugarWiki/{{Heartwarming|Moments}} though, because it's explained that [[spoiler:Evolto asked Soichi for "things he liked" for the organic Bottles, and Soichi's responses were all things and animals his daughter liked. Then, when asked for things that could "take their lives" for the inorganic Bottles, he eventually started giving illogical answers like comics and phones in a small effort to protect even just the concept of the things Misora loved]].

* Kazumi decides to leave nascita [[spoiler:after Sento attacked a berserk Banjo in order to protect his father]]. Gentoku agrees and starts to leave as well. Sawa tries to convince him to stay, but he simply unzips his jacket, revealing a FunTShirt that simply reads "Saraba" (Farewell) and heads up the staircase. Sawa blinks incredulously, then says "You could at least use your words instead of a T-shirt!" Even better, the reveal of the shirt is accompanied by a clip of Creator/NorioWakamoto shouting "ORRRRRA!!"
** Later on, Kazumi and Gentoku are talking about the situation, and the former says that they'll have to [[spoiler:find a way to get Shinobu Katsuragi on their side or else Sento won't be able to fight properly]]. Gentoku whips open his jacket again, this time revealing a T-shirt that reads "Agreed" (again, with a Wakamoto shout). Kazumi looks at him for a second, then asks [[OverlyPreparedGag "How long have you been wearing that?"]]

* When Gentoku learns about [[spoiler:why]] Utsumi [[spoiler:betrayed Evolto]], he can't stop himself from taking a jab at the scientist's Rider designation.

** In this world, Ryuga has black hair, is still going out with Kasumi, and still has his career as an MMA fighter. That's not the funny part. The funny part is when [[spoiler:the previous world's Banjo met him offscreen and starts complaining about it to Sento when they meet up again.]]

** While the above argument is going on, Souichi just walks away, shaking his head in exasperation before sitting down to take a nap.
* During Ryuga's story, Souichi shouts "Objection!" while [[Franchise/AceAttorney dramatically pointing a finger]]. Sento takes the objection like they're actually in a court of law.
** After being told his story sounds too convenient, Ryuga gets angry. In the middle of heatedly asking if Souichi thinks he's a liar, the Full Bottle purification machine suddenly dings behind him, causing him to let out a [[ScreamsLikeALittleGirl high-pitched shriek]].

** Even better, the show then gives us a flashback of Sento saving Sawa like a badass... then untransforming ''[[WhatAnIdiot right in front of her]]'' and skipping away while humming a little song to himself while Sawa picks up the matchbook that leads her right to Souichi's cafe.

* Misora offers to find out information for Sawa, which Ryuga is doubtful of. Cue Souichi once again screaming "OBJECTION", this time jumping ''completely out of nowhere''. Once again, Sento takes the objection without missing a beat.

* Last episode ended with Sento collapsed on the floor and losing consciousness from Blood Stalk's attack. How does this episode begin? [[MoodWhiplash With Souichi pulling Sento's cheeks to wake him up and the latter screaming.]]
* The purification machine is trying really hard to become a RunningGag, startling Souichi and Sento this time over. They try to outrun each other on the way there, nearly smashing into the machine.

* Souichi's reaction when he comes down into the lab only to find Sento pounding at the bottle matching wall with a mallet. He doesn't seem to believe his eyes, but pulls himself back together quickly and goes to stop Sento. [[spoiler:It goes into TearJerker soon afterwards as Sento breaks the bottle matching panel out of the wall, [[WhamShot confirming his suspicion]] that it's part of Pandora's Box and that Souichi has been lying to him the whole time.]]

* Nobody seems to like Souichi's coffee... not even Soichi.

** Part of this conversation is Souichi saying that Sento doesn't want to help Tatsuya because they used to be friends, but because he tries to help anyone he can.

* Soichi makes a cup of coffee that then gets passed among the cafe's inhabitants. No one wants to drink it so they all pull out canned coffee. Souichi's sad face increasing in intensity every time he tries to offer someone a cup only to be met with them cracking open a can is so absurd it crosses into hilarity.

* Sento takes a wild swing at each member of the gang - Soichi, Misora, Ryuuga and Sawa - to show that Pirate Departer has four stages of attack. Ryuuga restrains him before he tries to use it on Souichi. This turns Sento against Sawa whom he promptly points the crossbow at with slightly unhinged giggle.

** Made even more hilarious when you realize that this means, in-universe, Sento is chasing Souichi while rambling about "episode recap" that no one would understand.

* Souichi's reaction when he comes down into the lab only to find Sento pounding at the bottle matching wall with a mallet. He doesn't seem to believe his eyes, but pulls himself back together quickly and goes to stop Sento. [[spoiler: It goes into TearJerker soon afterwards as Sento breaks the bottle matching panel out of the wall, [[WhamShot confirming his suspicion]] that it's part of Pandora's Box and that Souichi has been lying to him the whole time.]]

** And then Sento completely deflates, almost sounding defeated at how easily Ryuuga can pick out Best Matches. [[spoiler: His energy comes back twofold however, when he goes into a creative frenzy building a Weapon for [=NininComic=].]]

** [[spoiler:Sawa]] also mentions that she knew about Build's identity and his secret base in nascita from the start, and [[spoiler: just bluffed her way in using a book of matches.]] [[SkewedPriorities Both Sento and Soichi are dancing ecstatically upon hearing this,]] because it means [[spoiler:their [[WhatAnIdiot careless mistakes]] from #2]] never happened.

* [[spoiler: Sento sees Sawa dangling from a balcony pursued by government men. His reaction is a [[DullSurprise bored]] ''this is the worst''.]]

--> '''[[spoiler: Misora]]:''' (disembodied dialogue) Hi! [[spoiler: (the camera shows Kazumi's Mii-tan wallpaper) It's your idol...]]
--> '''Kazumi:''' [[spoiler: (grins like a dork)]]
--> '''[[spoiler: Misora]]:''' [[spoiler: Mii-tan!]]
--> '''Kazumi:''' [[spoiler: (while mimicking the pose on his wallpaper) It's Mii-tan!]]

* [[spoiler: [=RabbitRabbit=]'s [[RubberMan stretching]] Rider Kick]] just stops right in front Rogue's face, causing him to flinch into a defensive position before realizing that the kick has stopped just in front of him. His attempt to counter is foiled by the kick building up enough power and snapping Build towards Rogue with enough force to bash him through the solid concrete wall of the arena and ''through another concrete wall outside the building.''

* Considering how much Sawa and Misora agonized over it and how much the episode preview and the music playing during the scene played it up, [[spoiler: Ryuga learning he's not human is a hilariously casual affair.]]

--> '''Sento''': ''(referring to the research handed to him by Sawa)'' [[spoiler: Hmmm... [[MoodWhiplash Banjo, it says here you're not human]]. ]]

** The funnier part is that even though this matches Mido's usual personality, we know [[spoiler: it's actually not him, but Namba.]]

* [[spoiler: Katsuragi's]] "what the hell" reaction to looking at Taro Satou's face in the mirror.
--> '''[[spoiler: Takumi Katsuragi]]:''' ''[[GratuitousEnglish Oh no!]]'' This is my face? How is this even physically possible?

** They talk about Katsuragi's title of ''Devil Scientist'', which [[spoiler: makes him turn around and sourly note that the ''devil'' part is uncalled for, before casually stating that he was the one who made Misora purify Fullbottles. [[NotHelpingYourCase The same process that would leave her in a coma before Sento made the machine to reduce the strain]].]]

* Kazumi is half-sitting, half-lying on the ground in depression over having the Hokuto Three's Lost Bottles taken from him. Ryuga hits him on the head with his fist (complete with a metallic clang out of nowhere [[note]] It is actually one of many comedic StockSoundEffects used in some modern Heisei Kamen Rider series when someone's head being whacked.[[/note]]) and nothing happens, which prompts him to tap on Kazumi's head a couple more times with his fingers (again accompanied by the metallic sound, albeit high pitched). Rest of the gang wonders why would Evolt need those bottles, only for Kazumi to suddenly get up and start choking Ryuga while yelling it doesn't matter.

* When Gentoku learns about [[spoiler:why]] Utsumi [[spoiler:betrayed Evolto]], he can't stop himself from taking a jab at the scientist's rider designation.

** Nanba Industries is now just a small factory, and Utsumi is just a normal factory worker. He ends up trying to replicate his infamous cane snap from Episode 38 with a faulty pipe only for the pipe to instead hurt his knee and send him collapsing to the floor in pain. Even better, everyone around just ignores this as if this happens every day.

* Apparently Sento archived and digitized all of their memories into 49 episodes and shows it to Banjo. 49 episodes, a.k.a the amount of episodes the series spans for. The former later pulls out a recording device, and begins performing a recreation of Episode 2's opening narration... in the exact way they did it then.

** It may not be what caused the outburst, but the subbed trailer has Ankh ask for today's icepop. That's one old gag. [[note]] Early into ''[[Series/KamenRiderOOO OOO]]'' Eiji had promised Ankh a year worth of icepops if he helps save [[TheChick Hina]]. They made a deal and from then on, Ankh got an icepop everyday. [[spoiler: He [[HeroicSacrifice died]] before the year ran out.]] That was six years (real time) ago.[[/note]] It wouldn't be very odd if Ankh said so simply to get this reaction.

* Sento finds [[spoiler: Utsumi]] in Nascita, making coffee - ''[[RunningGag good coffee]]'' to boot!

* [[spoiler:Namba]] Mido tries to make the recap of the episode alongside Sento until he inadvertently reveals a slight hint of his [[spoiler:real identity.]] His excuse? [[spoiler:That he's loyal to Nanba Heavy Industries.]] and they shouldn't spoil the episode. Despite the very same scene showing on-screen when he said that, ''is the spoiler itself''.

** There's something hilariously ironic in Vernage moving the entire nascita to another location to protect Pandora's Box, only for Ryuga to be forced to bring the Pandora Box to Evolt anyway.

** Banjou's initial reaction to Kuroto's AGodAmI rants? "This guy's an idiot, isn't he?" Then he sees the scene above with Onari and says "No, seriously, this guy's a total idiot." Considering [[IdiotHero who]] this is coming from…
** In the "Behind the Scenes" of the moment Onari tries to sweet talk Dan Kuroto, our "God" gestures at him and bends back almost 90°. [[https://i.imgur.com/60RDGCJ.jpg Onari can't help but give a confused look.]] The other actors behind the cameras can only laugh at the moment.

* Evolto's interactions with Banjo veer into this at certain points. After dashing away from Killbus for the first time, Evolto loses power and has to incubate again inside Banjo. This causes the muscle head to start smacking himself to get Evolto out. Then Yui wakes up and [[NotWhatItLooksLike Banjou smacking and yelling at himself]]. Gets even better when one remembers that she was ''unconscious'' when Evolto reappeared so she has no idea that he exists in the first place.

** Right after Killbus' defeat, Banjo then finds out why Evolto attacked Yui: he was trying to raise his Hazard Level by enraging him like old times,how Evolto responds to that? He just nonchalantly tells him to not to thank him while waving his hand in the same nonchalant way,and Banjo's reaction to that is pure gold! and it's not helping that Evolto chuckles to the response.

* The Super Hero Time opening for ''Build'' and ''Lupinranger VS Patranger'' has Sento in Rabbit Tank Sparkling swings the Drill Crusher near Banjou's, as Cross-Z Charge, head. He dodges out of the way and Banjou does a double take, his body language implying "Seriously, Sento?"

* Apparently, Souichi [[spoiler: or rather, Evolt]] ''really'' likes to make coffee, because he shows up in one scene with a briefcase/suitcase made ''specifically to carry coffee equipment''. Of course, the coffee was [[RunningGag still terrible]].

* Killbus, in general, is possibly the [[NarmCharm goofiest Rider villain]] in recent history. Initially he imitated Sento, and his general body language. Sounds like NightmareFuel, right? Well, it is. Until he sees a flamenco dancer on TV. From that point, everything he does is filled with NightmareRetardant. From his SillyWalk while using the power of Build to his habit of kissing his Kilbus Spider and its Bottle, he looks like the [[{{Camp}} Campiest character]] in the show, and possibly second to or ''surpassing'' [[Series/KamenRiderGaim Armored Rider Bravo]] in the entire ''franchise''.

* Evolto's interactions with Banjo veer into this at certain points. After dashing away from Kilbus for the first time, Evolto loses power and has to incubate again inside Banjo. This causes the muscle head to start smacking himself to get Evolto out. Then Yui wakes up and [[NotWhatItLooksLike Banjou smacking and yelling at himself]]. Gets even better when one remembers that she was ''unconscious'' when Evolto reappeared so she has no idea that he exists in the first place.

** Right after Killbus' defeat, Banjo then finds out why Evolt attacked Yui: he was trying to raise his Hazard Level by enraging him like old times,how Evolt responds to that? He just nonchalantly tells him to not to thank him while waving his hand in the same nonchalant way,and Banjo's reaction to that is pure gold! and it's not helping that Evolto chuckles to the response.

'''Evolt:''' (nonchalant wave of his hand) No need to thank me!\\

*** The exchange above is even funnier when Evolt is in his true form making the conversation a little weirder and more hilarious when you remember that fact that Evolt has no mouth in this form.
** Following Evolt's departure, Banjo helps Yui to her feet and quickly hugs him much to his shock, and Gentoku's reaction followed by pulling his jacket down revealing a shirt saying '''BEST MATCH?''' Banjo immediately denies anything and Yui kisses him on the cheek, and Kazumi (who hasn't scored yet) gets mad at the sight of that and promptly smacks Banjo and spanks him at least 2 times.

** They even went as far to try to find ''voice actors'' for everyone for what's implied to be an ''audio drama version of Sento's series pitch'', such as Misora and Evolt. Ryuga also mentions it was pretty hard to find people that sound like them. On top of this, this moment features a cameo from ''Evolt's actual V.A'' Tetsuo Kanao, accompanied by the Evol Driver's "Ciao!" and EvilLaugh.

* Nariaki Utsumi is shown testing steel rods by slamming them over his leg like Nanba's cane, and later into the film he even builds a ''metal cane'' that he tests with his tried and true knee. It seems some things never die.

* Evolt's interactions with Banjo veer into this at certain points. After dashing away from Kilbus for the first time, Evolt loses power and has to incubate again inside Banjo. This causes the muscle head to start smacking himself to get Evolt out. Then Yui wakes up and [[NotWhatItLooksLike Banjou smacking and yelling at himself]]. Gets even better when one remembers that she was ''unconscious'' when Evolt reappeared so she has no idea that he exists in the first place.
** Through the rest of the V Cinema, Evolt generally tries to interact with or appeal to Banjo in some way, normally through making Kilbus a bigger threat. But he also keeps calling Banjo ''[[FauxAffablyEvil partner]]'', which causes Banjo to get angry. This makes Evolt, in turn, try to not burst out laughing at his spawn's tantrum.

** [=SaiDryer=] falls into this as well. A rhinoceros is coming at you at ''top speed'', ready to [[ImpaledWithExtremePrejudice put its ivory to good use]]. The first thing you grab? A hair dryer. [[spoiler:TheReveal about the origins of the Best Matches makes this one better as it means Evolt asked Soichi what could be used to kill a Rhino and he honest-to-god bought a ''Hair Dryer'' as a legitimate answer.]]

* Evolto's interactions with Banjo veer into this at certain points. After dashing away from Kilbus for the first time, Evolto loses power and has to incubate again inside Banjo. This causes the muscle head to start smacking himself to get Evolto out. Then Yui wakes up and [[NotWhatItLooksLike Banjou smacking and yelling at himself]]. Gets even better when one remembers that she was ''unconscious'' when Evolto reappeared so she has no idea that he exists in the first place.
** Through the rest of the V Cinema, Evolto generally tries to interact with or appeal to Banjo in some way, normally through making Kilbus a bigger threat. But he also keeps calling Banjo ''[[FauxAffablyEvil partner]]'', which causes Banjo to get angry. This makes Evolto, in turn, try to not burst out laughing at his spawn's tantrum.
** Right after Killbus' defeat, Banjo then finds out why Evolto attacked Yui: he was trying to raise his Hazard Level by enraging him like old times,how Evolto responds to that? He just nonchalantly tells him to not to thank him while waving his hand in the same nonchalant way,and Banjo's reaction to that is pure gold! and it's not helping that Evolto chuckles to the response.

'''Evolto:''' (nonchalant wave of his hand) No need to thank me!\\

*** The exchange above is even funnier when Evolto is in his true form making the conversation a little weirder and more hilarious when remember that fact that Evolto has no mouth in this form.
** Following Evolto's departure, Banjo helps Yui to her feet and quickly hugs him much to his shock, and Gentoku's reaction followed by pulling his jacket down revealing a shirt saying '''BEST MATCH?''' Banjo immediately denies anything and Yui kisses him on the cheek, and Kazumi (who hasn't scored yet) gets mad at the sight of that and promptly smacks Banjo and spanks him at least 2 times.

* [[spoiler:[[NotSoDifferent Even Katsuragi calls Utsumi a cyborg]].]]

* After creating the Genius Bottle, Katsuragi does a [[Series/KamenRiderExAid Kuroto]] impression while saying the same "Am I not great? Am I not terrific? Am I not... a genius?" line Sento does after finishing a new invention. Apparently [[NotSoDifferent Katsuragi was the one]] [[NotSoAboveItall who came up with it]], which Misora [[LampshadeHanging comments on]].

* In the Pandora Tower, Utsumi is seen caressing his new Evol Driver, as if it is either a gift from above, or his "precious". [[NotSoDifferent Kind of like Namba and Pandora's Box.]]

[[folder: Episode 17: '''Rider War Starts!''']]

--> '''Sento:''' Banjou! Use the Twin Breaker!

[[folder: Episode 18: '''The Golden Warrior''']]

* Throughout the episode Kazumi behaves as though he knows Misora, hinting that they share a past together. [[spoiler: It turns out that he simply recognizes her as Mii-tan, who he's a ''huge fan'' of, almost like they were trying to remind you that his actor was the goofy [[Series/KamenRiderKiva Otoya]].]]

[[folder: Episode 21: '''The Unstoppable Hazard''']]
* Hokuto's Prime Minister Tajimi of all people, joined Sento in the recap and demanded explanation why are Touto's forces marching towards Hokuto. Sento denies it and quickly closes the recap by saying he will do something about it in this episode.

[[folder: Episode 22: '''Tears of Victory''']]

* There is something grimly hilarious in Tajimi being a ''very'' SoreLoser. Also, [[spoiler: she screws herself over by focusing everything on Touto and not paying attention to Seito, leading to her country being invaded and ''conquered'' when she wasn't paying attention and to her being detained by Seito's Guardians.]]
** On a similar note [[spoiler: Tajimi is almost hilariously offended at the revelation that Stalk was ''also working for Seito'' and that he'd betrayed her. Considering Stalk's business relationships with Faust, Touto, Sento, and possibly Nanba one has to wonder if she honestly thought his loyalties were truly with her or if she just had the worst pattern recognition skills in the world.]]
* The fact that [[spoiler: Kamen Rider Rogue, a character whose design incorporates broken glass patterns, has a ''fragile sticker'' on the back of his head.]]

* Sento inserts the new Rabbit bottle in the Build driver along with the old one. It goes well at first but then it blows up ''spectacularly'' into his and Ryuga's faces. This gives him an idea that he starts developing in his former gleeful manner. Ryuga watches Sento for a moment before pouting he doesn't understand him a single bit.

[[folder: Episode 27: '''The Hero's Counterattack''']]
* During the previous episode recap at the beginning of the episode, Prime Minister Mido butts in to arrogantly declare that Seito will take victory in the second fight of the representative match, only for Sento to confuse him with a long string of nonsense that hilariously enough is an accurate description of [=RabbitTank=] and its connection to the [[spoiler: Full Full [=RabbitTank=] Bottle.]]

** Even funnier, [[spoiler: when [=RabbitRabbit=] debuts, Mido actually refers to it as "the hoppity-hop... ka-blam... thing..." meaning that conversation ''actually happened''.]]

[[folder: Episode 28: '''The Genius Arrives With a Tank''']]

* After Sawa [[spoiler: gives Sento the signal that the Nabeshimas are in the clear, he sighs and gets up as if Rogue didn't just serve him a full course ass-whooping.]]

** [[spoiler: For context, Kazumi agreed to help Sawa with the Nabeshima's family rescue mission on the condition that he will get to have a handshake with Misora, only to find Misora and Ryuga holding hands.]]
* After [[spoiler:Stalk swapped Nanba's face into Prime Minister Mido]], he bites into his taiyaki like [[Manga/DeathNote Light with a potato chip.]]

[[folder: Episode 29: '''The Opening Bell Rings''']]
* [[spoiler: Nanba]] Mido acts like an conductor of an orchestra in the beginning of the episode and then keeps part of the act ongoing through the episode. When activating part of the Pandora Box, Stalk makes similar gestures.

[[folder: Episode 30: '''The Truth of Pandora's Box''']]
* [[spoiler: Nanba]] Mido tries to make the recap of the episode alongside Sento until he inadvertently reveals a slight hint of his [[spoiler: real identity.]] His excuse? [[spoiler: That he's loyal to Nanba Heavy Industries.]] and they shouldn't spoil the episode. Despite the very same scene showing on-screen when he said that, ''is the spoiler itself''.

** When Sento shows the screencap of the 2nd episode, Banjou and the others smile as they listen to the narration before Sento punches it away since again, that's not the part he wants to hear.

* The three riders kicking the four combo Guardians isn't funny, it's [[SugarWiki/MomentOfAwesome awesome]]. However Stalk opening the side of Pandora's Tower unexpectedly causing them to all go [[OhCrap "Eh]][[BigWhat ?!"]] in unison as they go careening inside also isn't funny, it's ''hilarious''.

[[folder: Episode 31: '''Surging Magma''']]

* As absolutely ''freaking awesome'' as [[spoiler: Cross-Z Magma's debut fight is, it's pretty funny to learn that the steam coming off the suit isn't just a cool effect. The suit is quite literally steaming hot, as Ryuga finds out when he seems to come down off the adrenaline rush of fighting Blood Stalk and starts twitching and stumbling around yelping out things to the effect of "that's hot!"]]

* Just think about how the [[spoiler: ArtifactOfDoom and the ability to control it is now in possesion of the franchise's biggest dumbass in 16 years]]. [[note]] That's about the time from [[Series/KamenRiderRyuki Ryuki]]. Shinji Kido being a dumbass is the only thing that the [[TheLancer other]] [[AmoralAttorney three]] [[AxeCrazy riders]] had (and could) ever agreed on.[[/note]]

[[folder: Episode 32: '''Programmed Tragedy!''']]

--> '''Sento''': ''(referring to the research handed to him by Sawa)'' [[spoiler: Hmmm... [[MoodWhiplash Banjou, it says here you're not human]]. ]]

** The funnier part is that even though this matches Mido's usual personality, we know [[spoiler: it's actually not him, but Nanba.]]

[[folder: Episode 33: '''Evol the Final Weapon''']]

[[folder: Episode 34: '''The Separated Best Match''']]

* What should have been a shocking PlotTwist when Ryuga [[spoiler:is turned into the next vessel for Evolt]] is greatly marred by Ryuga inexplicably developing a FunnyAfro.
** It's likely most of the hairstyle change resulted from [[spoiler: the energy discharge from Evolt and Ryuuga's explosive punches]], but... That doesn't explain how his braids came out so seamlessly, or why [[spoiler: Evolt]] has apparently decided to '''keep''' the look in the next episode preview.

[[folder: Episode 35: '''The Tower Of Destruction''']]

** Kazumi getting sent flying by Evolt is not funny. Kazumi getting incapacitated via Evolt [[GroinAttack casually shooting him in the crotch]] and then following up with a surge of power that sends him flying ''[[KickThemWhileTheyAreDown that he also aims at Kazumi's crotch]]'' is ''hysterical.''

[[folder: Episode 36: '''Evolt Hunts the Stars''']]
* During the previous episode recap, Kazumi declares that since [[TheBadGuyWins Evolt has won]], Kamen Rider Build has ended and will be replaced by a Romcom between him and Misora. Sento slaps him and proceeds to introduce the episode.
* Evolt presents the newly created Evol Trigger, which he claims is the true power of the Pandora Box, [[YourPrincessIsInAnotherCastle only for it to do nothing when he presses it]]. The music immediately cuts out and the dramatic whirlwind stops as the realization sinks in.
** On top of that, Evolt reacts to his plans being delayed in a huge way with what amounts to "Ah well, that's how it is sometimes."

* [[spoiler:When Evolt has taken over Sento, he reaches into himself to create a new Evolbottle with Sento's essence and it turns out to be the Rabbit Evolbottle. Evolt actually seems ''disappointed'' that Sento's essence didn't provide him with a Tank Evolbottle.]]
-->'''Evolt:''' Oh well.
** [[spoiler: Even better, it turns out the Evol Driver toy does in fact have special programming for an Evol Tank form.]]

[[folder: Episode 37: '''The Ultimate Phase''']]
* Sento narrates the opening narration as usual when Ryuga barges in, [[spoiler:demanding that he prove if he's Evolt or Sento by making a cup of coffee and then ''immediately'' stating he's Evolt because the coffee was awful. Evolt's reaction is quite literally "Oh well, you got me there."]]
* Sawa walks into the lab at the moment Vernage posseses Misora to protect them from Evolt.

* Evolt's surprised reaction when he teleported into nascita only to see a huge gaping hole. He gets steaming mad that someone is ruinning his plans all the time.

* How does Ryuga [[spoiler: get his powers back? You guessed it. Punching something ''[[WhenAllYouHaveIsAHammer really hard.]]'']]

[[folder: Episode 38: '''Mad World''']]

* [[spoiler: Katsuragi]] entered the battle in [=RabbitRabbit=] form. And then proceed to complain that the form is way too advanced for him.

* Evolt laughing evilly when [[spoiler: Utsumi goes off the deep end after Nanba kicked the bucket]].
* Utsumi's [[spoiler: evil grin is nowhere near as threatening as the one Gentoku used to have.]] The fact that the [[SoundtrackDissonance cheerful and upbeat "Be The One" is playing while this is happening]] does not help.
* Even better, [[spoiler: Mad Rogue has ''facial hair''. The bat is a ''unibrow'' and the mustache is ''made from an engine!'']] This really ''is'' a [[TitleDrop Mad World]].

[[folder: Episode 39: '''The Unstoppable Genius''']]

* At the start of the episode, everyone ponders about why Evolt is trying to take over the country instead of just destroying it like he has the power to do now. Cue Banjou hamming it up while suggesting that it's to "Get rich, and party hard, right?!" while yellow disco lights and sparkles are lit behind him and money falls from the sky with Banjou dancing. Cut to the others seeing no lights and Banjou flailing his arms dancing like an idiot and babbling about money.
** Then Katsuragi remarks that Banjou make simians look advanced, causing Banjo to get smacked in the head with a cartoon monkey for whatever reason. Kazumi and Misora nod in agreement, causing Banjo to stomp his feet in a brief tantrum.
** Later, in the midst of a serious talk where Kazumi assured Banjou that he thinks he's human... and then ruins the moment by calling him closer to a chimpanzee. Cue the cartoon monkey falling on Banjou's head again before dashing off somewhere.
* After creating the Genius Bottle, Katsuragi does a [[Series/KamenRiderExAid Dan Kuroto]] impression while saying the same "Am I not great? Am I not terrific? Am I not... a genius?" line Sento does after finishing a new invention. Apparently [[NotSoDifferent Katsuragi was the one]] [[NotSoAboveItall who came up with it]], which Misora [[LampshadeHanging comments on]].

* In the Pandora Tower, Utsumi is seen caressing his new Evol Driver, as if it is either a gift from above, or his "precious". [[NotSoDifferent Kind of like Nanba and Pandora's Box.]]
** All of Utsumi's antics are, in a demented way, downright hilarious. Even his mad evil smile is too ridiculous to be taken seriously. He and Evolt work together like a [[IncrediblyLamePun Best Match]].

[[folder: Episode 40: '''The Final Revolution''']]

[[folder: Episode 41: '''The Truth Behind Best Matches''']]

* Sento's [[CatchPhrase "winning formula"]] for beating Evol...is [[StatingTheSimpleSolution beating him before he can use Black Hole form]]. Mostly because Evolt decided to be a cocky bastard and showed up in the weakest of his four forms.

** As Sento laments that everything went AllAccordingToPlan for Evolt, Misora pets him on the head while everyone else offers him their popcorn and drinks, except Gentoku, who offers ''his hat''.
* While this probably crosses over into NightmareFuel, the fact that Best Matches come from [[spoiler: Evolt asking Souichi to name 30 things from Earth[[note]]Which created the Organic [=FullBottles=][[/note]], and then 30 different ways to kill those things[[note]]Which are what the Inorganic [=FullBottles=] based on[[/note]]]] becomes hilarious if you picture situations like [[spoiler: [[ThereIsNoKillLikeOverkill using a tank to blow up a rabbit]] or [[ImprobableWeaponUser killing a ninja with a manga]]]]. The [=FullBottles=] have been turned into a well of BlackComedy in just one scene.
** The reveal also veers into TearJerker and SugarWiki/{{Heartwarming|Moments}} though, because it's explained that [[spoiler: Evolt asked Souichi for "things he liked" for the organic Bottles, and Souichi's responses were all things and animals his daughter liked. Then, when asked for things that could "take their lives" for the inorganic Bottles, he eventually started giving illogical answers like comics and phones in a small effort to protect even just the concept of the things Misora loved]].
* Evolt throws an ''honest-to-god childish temper tantrum''. He just starts punching and yelling at Sento thoughtlessly, because his plans have been delayed once again and he just can't take it anymore. Genius Form mostly shrugs it off. Things do turn ''very dark'' again, when Evolt knocks Sento down with a Black Hole Finish after said tantrum reveals that his newfound emotions allow him to ''raise his Hazard Level'' and caps it all off by stating he is going to save him for last so he could fail and see the world end around him. That said, having the EldritchAbomination bent on making you suffer because it's petty and you flipped it off is still [[{{Understatement}} really bad]].

[[folder: Episode 42: '''Legacy of Doubt''']]

[[folder: Episode 43: '''Another Build''']]
* Kazumi decides to leave nascita [[spoiler:after Sento attacked a berserk Banjou in order to protect his father]]. Gentoku agrees and starts to leave as well. Sawa tries to convince him to stay, but he simply unzips his jacket, revealing a FunTShirt that simply reads "Saraba" (Farewell) and heads up the staircase. Sawa blinks incredulously, then says "You could at least use your words instead of a T-shirt!" Even better, the reveal of the shirt is accompanied by a clip of Creator/NorioWakamoto shouting "ORRRRRA!!"

[[folder: Episode 44: '''The End of Evolt''']]

[[folder: Episode 45: '''The Scientist of Hope''']]
* The episode recap has Gentoku, Kazumi, and Ryuga arguing on who is the MVP in the fight against Evolt.

* The reason Evolt's final monster form lost the battle despite his overwhelming power? He succumbed to his habit of toying with his victim instead of immediately killing them, giving Sento a chance to get his HeroicSecondWind.

[[folder: Episode 46: '''An Oath to Be The One''']]

[[folder: Episode 47: '''Zero Degree Flame''']]
* [[spoiler: In the end, Sento was right. Utsumi really is a cyborg! He died after getting shot by Gentoku and falling from the bridge in #12 and has been revived by Evolt.]] That's just about the only thing that is not bitter (or not completely so) in this episode.
* When Gentoku learns about [[spoiler: why]] Utsumi [[spoiler: betrayed Evolt]], he can't stop himself from taking a jab at the scientist's rider designation.

[[folder: Episode 48: '''To The World Of Love And Peace''']]
* Evolt calls humans adorably stupid. That's obviously not funny in itself, but he '''''is''''' right... in an absurd, morbidly black comedy sort of way. [[note]] For starters, there is the Darwin Award, ''Series/TheSmokingGunPresentsWorldsDumbest'', the Dunning–Kruger effect and the list goes on...[[/note]]

[[folder: Episode 49: '''The Tomorrow Build Will Create''']]

** In this world, Ryuga has black hair, is still going out with Kasumi, and still has his career as an MMA fighter. That's not the funny part. The funny part is when [[spoiler: the previous world's Banjou met him offscreen and starts complaining about it to Sento when they meet up again.]]
* [[BookEnds Once again]], Sento and Ryuga are riding off on the Machine Builder. Also, once again, Sento points out that Ryuga's fly was down. Naturally, [[RuleOfThree once again]], Banjou violently shakes Sento and the bike for not telling him earlier and calling him stupid.
** Even better, apparently it's been undone since the ''the start of the final battle with Evolt''.
* Apparently Sento archived and digitized all of their memories into 49 episodes and shows it to Banjou. 49 episodes, a.k.a the amount of episodes the series spans for. The former later pulls out a recording device, and begins performing a recreation of Episode 2's opening narration... in the exact way they did it then.

* After everything that Banjou's gone through, how do he and Sento make it day to day? Selling Sento's inventions as toys. He even gets yelled at by a bratty kid in a park who doesn't like what's on the table.
** They even went as far to try to find ''voice actors'' for everyone for what's implied to be an ''audio drama version of Sento's series pitch'', such as Misora and Evolt. Ryuga also mentions it was pretty hard to find people that sound like them. On top of this, this moment features a cameo from ''Evolt's actual V.A'' Tetsuo Kanao, accompanied by the Evol Driver's "Ciao!" and EvilLaugh.

* Evolt's interactions with Banjou veer into this at certain points. After dashing away from Kilbus for the first time, Evolt loses power and has to incubate again inside Banjou. This causes the muscle head to start smacking himself to get Evolt out. Then Yui wakes up and [[NotWhatItLooksLike Banjou smacking and yelling at himself]].

--->'''Banjou:''' So you went after Yui so you could raise my Hazard Level?\\
'''Evolt:''' (nonchalant wave of his hand) No need to thank me!\\
'''Banjou:''' (annoyed) Who would!?
*** The exchange above is even funnier when Evolt is in his true form making the conversation a little weirder and more hilarious when remember that fact that Evolt has no mouth in this form.
** Following Evolt's departure, Banjou helps Yui to her feet and quickly hugs him much to his shock, and Gentoku's reaction followed by pulling his jacket down revealing a shirt saying '''BEST MATCH?''' Banjou immediately denies anything and Yui kisses him on the cheek, and Kazumi (who hasn't scored yet) gets mad at the sight of that and promptly smacks Banjou and spanks him at least 2 times.

* [[https://www.youtube.com/watch?v=OW1y8FNibDU This]] ''Heisei Generations FINAL'' show has Atsuhiro Inukai/Sento do his best Taro Satou impression, Seto Toshiki/Hiiro Kagami steals Ryuuga's usual "I won't lose!" catchphrase, Ukyo Matsumoto/Taiga changes his usual line about Gashats to [=FullBottles=] and Reina Kurosaki/Nico steals Parado's CatchPhrase leaving Shouma Kai/Parado momentarily speechless when it's his turn. Hiroki Ijima/Emu and Atsuhiro Inukai also joke about which one of them is the [[SempaiKohai sempai]] (senior) and who is the kohai (junior), as Inukai is actually older than Ijima despite playing the Rider that comes later.

* Nearly all of the Best Matches have some sort of connection in addition to the Organic/Inorganic formula. Some of them are hilarious because of the mental images they create, like [=HachiMarine=] form. One could only imagine the panic of being trapped miles below the ocean surface with ''wasps'' loose in the sub. [[spoiler: The revelation that the Inorganic Fullbottles are meant to be things that can destroy the Organic Fullbottles makes nearly every Best Match into a hilarious case of ThereIsNoKillLikeOverkill.]]
** [=SaiDryer=] falls into this as well. A rhinoceros is coming at you at ''top speed'', ready to [[ImpaledWithExtremePrejudice put its ivory to good use]]. The first thing you grab? A hair dryer. [[spoiler: TheReveal about the origins of the Best Matches makes this one better as it means Evolt asked Souichi what could be used to kill a Rhino and he honest-to-god bought a ''Hair Dryer'' as a legitimate answer.]]

[[/folder]]

* When it looks like Sento is going to be late for his first day at work, he smugly reveals his latest invention--a motorcycle that unfolds from a smartphone. When Souichi asks if Sento plans to call in sick, Sento goes along with it and begins pantomiming doing so before immediately stating "Of course not!" To make things even funnier, the shot immediately cuts from Sento with the phone to his ear to him poutily denying that he's going to call in sick.
** He announces his departure, and is then stopped by Souichi because he's still inside the café, and the cycle is facing the bar, ''[[FailedASpotCheck away from the door]]''.

'''Souichi''': -not go anywhere right now. You're still inside the café.

* During Ryuuga's story, Souichi shouts "Objection!" while [[Franchise/AceAttorney dramatically pointing a finger]]. Sento takes the objection like they're actually in a court of law.

** After creating the Hawk Fullbottle, Misora quite literally walks all over Ryuga before slumping onto her bed and threatening to ''cut'' anyone who wakes her up. Later when Ryuuga and Sento's arguing wakes her up she hurls a spatula hard enough to lodge it into the Bottle Purification machine to prove that ''she wasn't kidding''.

[[folder: Episode 4: '''The Testimony Will Be Zero''']]

* Soichi and Misora take over reading the introduction from Ryuga and Sento. Ryuuga doesn't seem to mind, but [[SmallNameBigEgo Sento]]...

'''Souichi''': What kind of villain could be as stylish as me?
** [[spoiler:This later becomes HarsherInHindsight when we learn Soichi is Blood Stark.]]

* Sento and Souichi have a serious conversation about who Souichi was and how he came to start working with Sento... while playing foosball. And they both seem to be more interested in the latter.
* Nobody seems to like Souichi's coffee... not even Souichi.

* This exchange between Ryuuga and Tatsuya:
--> '''Ryuuga''': Who is this weird guy?

--> '''Ryuuga''': ''(headbutts Tatsuya, knocking him to the ground)''

--> '''Ryuuga''': So what? ''(headbutts Tatsuya, knocking him down again)''

--> '''Ryuuga''': If you test it on me, there'll be hell to pay.

[[folder: Episode 6: '''Moonsault of Anger''']]
* [[RunningGag The summary of last week's episode]] begins with Sento declaring that he's going to read the introduction this time. He begins the recap, only to realise the script is calling him a "self-proclaimed hottie brilliant physicist", and immediately starts demanding who rewrote it (pointedly accusing Misora). Then Ryuuga jumps in and starts reading the introduction, much to Sento's chagrin.

* Souichi has heart-to-heart conversation with Ryuuga while making him a coffee. This emotional moment is ruined when Ryuuga tastes the coffee and predictably sputters over it's bitterness.

---> '''Ryuuga:''' ''(sourly)'' That's just so God-like, Buddha-like and Sento-like, right?

* Misora poking the unconscious Ryuuga with her plush cat. When he doesn't move, she procclaims him to be dead in [[MoodDissonance upbeat tone]]. Sento tells her that Ryuuga is going to wake up soon. That doesn't stop Misora from continuing to poke him in a way that makes it look more like a beating then anything, accompanied by a repeating bouncy "boing" sound effect. Not that he wouldn't deserve some of it at that point.
* Sawa asks Misora if she has a boyfriend. Misora responds by uncontrollably shaking hot sauce onto her pizza and stuttering like a madwoman. Then Sawa asks if she prefers Sento or Ryuuga more, causing Misora to leap up from the table and scream at a pitch that only dogs can hear.

* Just the immediacy with which Sento and Ryuuga go back to being best friends after their fight, making Misora feel stupid for even worrying about them.
* Sento and Ryuuga sneak around the Guardians disguised as construction workers the same way Ryuuga and Sawa moved around in Seito dressed up as delivery people. Apparently, worker uniform and baseball cap are all you need to walk around unnoticed.
* Sento explains that he created the [=CrossDragon=] as a pet that would keep an eye on Ryuuga, who is not amused by this. He then tries to wave the [=CrossDragon=] away and gets (miniature) flames spat on him for his troubles.

** Luckily, Ryuuga is saved when the Cross-Z Dragon comes over and sucks the poison out of his body. This in itself is a SugarWiki/MomentOfAwesome, but what's funny is the tiny dragon vomiting up a miniature spray of poison while Ryuuga recovers.
* As Blood Stalk leaves the collapsing research facility, he gives Ryuuga a friendly pat on the shoulder, which Ryuuga immediately brushes off. Stalk's resulting body-language just screams "well, that was just uncalled for."

[[folder: Episode 7: '''The Devil Scientist''']]
* Ryuuga follows Sento around the lab because of the events of #6, [[spoiler: namely the implication that Sento has killed Katsuragi]]. His (at times bizarre) distrusting scowls are just the cherry on the top.

* The purifier machine strikes again. Sento and Ryuuga argue in front of it, not paying any attention to the fact that new bottle is nearly ready. You can countdown to when it beeps and scares them.

--> '''Ryuuga:''' Who are you calling an ape?!

* Souichi makes a cup of coffee that then gets passed among the cafe's inhabitants. No one wants to drink it so they all pull out canned coffee. Souichi's sad face increasing in intensity every time he tries to offer someone a cup only to be met with them cracking open a can is so absurd it crosses into hilarity.
* After Sawa explains the Sky Road and how expensive it is, Sento starts looking to everyone else for funds. Souichi refuses because he still works part-time jobs at his age, and can't even serve coffee right. Sawa refuses because she barely makes enough for herself and her friend's wedding is coming up. Ryuuga, who still suspects Sento and is a wanted fugitive who barely even owns the clothes on his body (they're maybe ''Sento's'' clothes), simply rebuffs him with a blunt "hell no". Finally, after looking over everyone in a depressed slump, Misora relents and starts a donation drive in her Net Idol persona.

* Ryuuga in a clown costume. It must be seen to be believed.
** A group of children pretty much ZergRush Ryuuga while he is in said costume, spoiling his disguise instantly.
** After paying [[spoiler: the smuggler to take them across the Sky Road (said smuggler being also over the top with gelled hair and super dark sunglasses he peers over)]], the camera pans to show Ryuuga, dressed as a clown, musing on how Misora is "kind of awesome." Sento agrees... Then seems to ''just realize'' what Ryuuga is wearing.

* The children at Mrs. Katsuragi's school found Sento and Ryuuga whose are sulking in a bridge, and call them "old dudes". Ryuuga silently protest that "we aren't old dudes, we're young dudes".

* Ryuuga fights Stalk with [=CrossDragon=] spewing fire everywhere, ''even on him''.

[[folder: Episode 8: '''What The Memories Tell You''']]
* The episode, as usual, starts with a review of the previous episodes… except this time, half of it is Ryuuga baiting Sento into talking about his weapon instead of actually describing what happened last episode. Also [[spoiler: Ryuga admitted Katsuragi as a true genius, unlike Sento. This becomes funny after the reveal that Katsuragi is Sento.]]

** On more grimly hilarious note, their assumptions that Touto Goverment creates Smash for military purposes are ''[[RightForTheWrongReasons technically correct]]'' [[spoiler: given that Faust is a rogue faction of Touto's government.]]
* The dramatic conversation between Sento and Mrs. Katsurugi is interrupted by Ryuuga's stomach growling. They are served fried egg rolls she had been preparing for her son. Ryuuga tries to wolf down the meal, but stops and pouts about it being too sweet. Sento scolds him for being impolite and takes the plate away.
* Ryuuga [[RealMenHateSugar complaining]] about Sento's burp while they are in the trunk of car heading to Touto.
--> '''Ryuuga:''' Ugh, your burps smells sweet! You have eaten too much tamagoyaki!

** Mind you, Ryuuga's fighting the Smash while this is happening and at this, he turns around and looks at Sento with an expression that screams "dude, really, now?"

* As our heroes head off to save the day, Misora hands Sento the Fire Truck Full Bottle. Souchi also hands Ryuuga a bag, which he initially takes enthusiastically... until he sees it's another disguise. Not only is his surprise utterly hilarious, but it explains just where he's been getting his outfits from.

[[folder: Episode 9: '''The Project Build Trap''']]

* Sento claiming that Utsumi is like a cyborg. In a ''Kamen Rider'' series, this is some serious TemptingFate. [[spoiler: This becomes JokeAndReceive when Utsumi is revealed as a cyborg much later.]]

[[folder: Episode 10: '''Technology of Destruction''']]

* Sento saves Ryuuga from Night Rogue and Blood Stalk. This exchange ensues:

* [[spoiler: Gentoku's SlasherSmile at everything going according to plan, [[TyrantTakesTheHelm allowing him to take control of Touto]] ''shouldn't'' be funny. However his absurd mustache-twirling and the way the scene's shot makes it seem more hilarious than scary.]]

[[folder: Episode 11: '''Burn, Dragon!''']]
* After absent on previous episode, the pre-episode banter is coming back, as hilarious as ever. In there, Sento told the viewers that he lost his Fullbottles, and then...

[[folder: Episode 12: '''Theory of Conspiracy''']]
* The opening narration has Sento suggest that Ryuuga should be called Kamen Rider Meathead.
* When [[spoiler: Sawa]] talks about being a spy for Namba Heavy Industries, everyone ponders about it gloomily... and Ryuuga just stuffs his mouth with ramen.
** [[spoiler: Sawa]] also mentions that she knew about Build's identity and his secret base in nascita from the start, and [[spoiler: just bluffed her way in using a book of matches.]] [[SkewedPriorities Both Sento and Soichi are dancing ecstatically upon hearing this,]] because it means [[spoiler: their [[WhatAnIdiot careless mistakes]] from Episode 2]] never happened.

* Misora is pondering if the Namba Heavy Industries forced [[spoiler: Sawa]] to spy on them. The camera then moves to show [[spoiler: Sawa]] chained to a beam in similar way like Ryuuga was in early episodes.
** When [[spoiler: Sawa]] provides exposition, Misora sticks her plushies around the corner to peek at [[spoiler: her]] instead of doing so herself.
* Sento's face when Ryuuga refuses to give him the Dragon Bottle and takes the spotlight as Kamen Rider himself.

* Ryuuga tells Sento that he did pretty well as his assistant following the battle. Sento tells him that he did pretty well for an amateur.
* Sento takes a wild swing at each member of the gang - Souichi, Misora, Ryuuga and Sawa - to show that Pirate Departer has four stages of attack. Ryuuga restrains him before he tries to use it on Souichi. This turns Sento against Sawa whom he promptly points the crossbow at with slightly unhinged giggle.

* Touto Government forces comes to arrest Night Rogue while he is sitting [[SlouchOfVillainy slouched]] in his tacky chair. It gets even better when you realize [[spoiler: [[NotSoAboveItAll it's the normally stoic, serious Utsumi wearing the suit!]]]]

[[folder: Episode 13: '''Who Takes Off the Veil''']]
* Ryuuga asks Sento about the big info that supposedly came from Nabeshima. Sento tells him that it's ''train your pecs more''. Ryuga seriously considers it for a moment before realizing that Sento is pulling his leg.

* Souichi and others tried to bait Sento into getting out of the lab using... Sento's favorite grilled fish. It '''worked'''.

** The duo's double henshin is followed by Ryuuga stepping in front of Sento to take all the fame for himself only to be smacked aside with metallic clang.
** Ryuuga ducks out of the way just as Sento shoots Guardians with Kaizoku Hasher. And then Sento run past him while saying "Coming through~" like he's a train.

* At the end of the episode, when [[spoiler: Souichi]] takes away all the bottles and the Pandora Box, he used the classic green cloth with white swirls commonly associated with thieves in Japan. As if he needs to make it more obvious he's stealing them away.

[[folder: Episode 14: '''The False Kamen Rider''']]
* The recap had Sento out of breath since he was recapping while running to chase Souichi. He even complained about it.

* Both Sento and Souichi got tired of running around. Souichi acted so chill he simply asked Sento to forgive him. Not to mention he simply left with a "Ciao!" and walk away.

[[folder: Episode 15: '''Judging Sento Kiryu''']]

* [[spoiler: Gentoku joins Guardians raiding nascita and searches around for Pandora's Box himself. He opens the fridge in dramatic manner and... finds normal groceries. Someone (most likely Sento) clearly thought ahead while they were moving Pandora's Box to keep Gentoku from finding the secret lab.]]

* Gentoku revealing that [[spoiler: Sento is Takumi Katsuragi]] is not funny. The fact that he indulges in infamous slightly unhinged EvilLaugh afterwards on the [[NarmCharm other hand]]…

[[folder: Episode 16: '''Weaponry Hero''']]

** [[RealityEnsues And he ends up breaking his knee testing it out.]]

* What should have been a ShockingSwerve when Ryuga [[spoiler:is turned into the next vessel for Evolt]] is greatly marred by Ryuga inexplicably developing a FunnyAfro.

* Sento hands Gentoku an upgrade, but is interupted by Misora calling Gentoku and making him agree to go shopping with her for normal clothes. The leverage she uses? Threatening to cover his meal with green peppers. [[note]] Recap of #41 has Gentoku saying that he refuses to eat peppers.[[/note]] He takes off running towards the train station screaming '''GREEN PEPPERS'''.
** Sento's reaction can be summed up as ''What the actual [[SymbolSwearing *bleep*]]?'' Sometimes, it's just hard for him to deal with how weird his [[FamilyOfChoice family]] is.

* One of Gentoku's outfit looks remarkably like [[Series/KamenRider Kamen Rider #1]]. Misora even tells him he looks like a bug [[note]] Kamen Rider #1 is grasshopper-themed.[[/note]]
* Gentoku comes out of a changing booth in a quasi-fashion show to display different outfits. Of course, each one of them is as horrendous as the last. What makes this even funnier is the distortion effects applied over Misora's horrified reactions to each outfit.
* Evol makes Genius [=FullBottle=] disappear with what is basically a stage magician's trick. It would be funnier if he didn't try to murder Sento immediatelly afterwards.

* Even a ten years old can tell Gentoku how much his outfits suck!
* This special is essentially the story about how Gentoku got the leather jacket he wears in ''Be The One'' movie and the episodes afterwards.

* During the battle, Ryuga reminesces about the heart to heart conversation he had with Kazumi earlier. That's good and all, but it turns out that Kazumi's idea of easing the mood was to [[GettingCrapPastTheRadar imply]] there is something [[{{HoYay}} more]] between Ryuga and Sento. Underlined with him ''eating a [[UnusualEuphemism carrot]]''.

** [[https://www.youtube.com/watch?v=FrJH_mdjXt4 Kuroto unveils the Kamen Rider Build Gashat]], which lets him fight the Nebula Bugsters. Unfortunately it's untested, so it shorts out his transformation partway through, leaving him and the Bugster he was fighting staring at each other in confusion. Then Kuroto pops the Gashat into his Gashacon Breaker and pounds on the Bugster like it was an errant nail [[FastForwardGag in high speed]].

* The first scene after the opening is nascita gang starring into the Pandora Box quizzically, shot from the inside of said box.

** After that, when Kazumi asked where's Gentoku, we gets to see him....awkwardly trying to get some soumen alone.

** The entire thing gets even more hilarious because of the background music, of ALL the background music we get Offenbach's Infernal Galop A.K.A. ''CAN CAN''!

*** GeniusBonus alert: bananas are a natural source of potassium, and far more practical than you garden-variety fitness supplements.

* The fact that [=RabbitTank=] Sparkling, the upgrade form for this season, ends up taking the form of... a can of soda. One that makes fizzy pop noises when shaken and sounds like a can opening when triggered! There's something to be said for [[{{Pun}} opening a can of whoopass]]...

** ''Then'' Sento suddenly bursts in, grabs Misora by the shoulders and tells her "it's love", completely stunning her. He then reveals that he loves that he found an opening in the Skywall, and skips merrily off, leaving Misora collapsed in a heap on the floor.

** Then Katsuragi remarks that Banjou make simians look advanced, causing Banjo to get smacked in the head with a cartoon monkey for whatever reason. Kazumi and Misora nodding in agreement.

** After the worlds merge, the first shot is of a meadow with [[VisualPun rabbit]] hopping about. It then shifts to Sento laying on said meadow, holding a [[Series/KamenRiderZiO Ridewatch]].

[[folder: Other]]

* Toei's official page for Build #44 has a [[https://www.toei.co.jp/tv/build/story/1213073_2766.html picture]] [[note]]Scroll down under the episode guide and highlight. It's at the end of production notes.[[/note]] of Sawa holding ''life-sized Mii-tan pillow''. Imagine the reaction that Kazumi is going to have upon seeing it.

* Evolt calls humans adorably stupid. That's obviously not funny in itself, but he was right... in an absurd, morbidly black comedy sort of way. [[note]] For starters, there is the Darwin Award, ''Series/TheSmokingGunPresentsWorldsDumbest'', the Dunning–Kruger effect and the list goes on...[[/note]]

* Evolt calls humans adorably stupid. That is (obviously) not funny in itself, but he was right in an absurd, morbidly black comedy. [[note]] For starters, there is the Darwin Award, ''Series/TheSmokingGunPresentsWorldsDumbest'', the Dunning–Kruger effect and the list goes on...[[/note]]

** After the worlds merge, the first shot is of a meadow with [[VisualPun rabbit]] hopping about. Then it shifts to Sento laying on said meadow, holding a [[Series/KamenRiderZiO Rider Watch]].

* The entrance to Sento's secret lab? A refrigerator. Not unlike the [[Series/KamenRiderFourze Rabbit Hutch]], except ''smaller'' and apparently minus the cosmic energy mumbo jumbo.
