History Recap / KamenRiderBuildEp38MadWorld

* SurprisinglyRealisticOutcome: This episode shows that despite being the creator of the Build Driver, Katsuragi struggled more than the rest of Riders due to not being used to the current upgrades Sento has created throughout the series. For example: he had a hard time controlling the fast [=RabbitRabbit=] as the last form he used before losing his memories was [=GorillaMond=], a form that's more of a MightyGlacier than the former's LightningBruiser capabilities. Furthermore, he tried to use the Pandora Box piece as an empowering device, but Sento created it primarily to raise his Hazard Level in order to cause a suicide attack as a side-effect of his body being unable to handle the stress of the increased Hazard Level.

* AlasPoorVillain: [[spoiler: After spending so much time as the enemies of the Nascita group, both Fu and Rai die rather tragically this episode after failing to slow down Evolt in any capacity.]]

* DeadlyUpgrade: The Hell Bros get dosed with more Nebula Gas in an attempt to reach up to Evolt's level, but Utsumi warns them that they will die if forced out of their transformation. [[spoiler:Which is what exactly happens to them]].

* {{Foreshadowing}}: [[spoiler: Evolt uses the Evol Trigger and the five panels of the Pandora Box the heroes left behind to produce a seventh panel and begins slotting in Smash Bottles and converting them into Lost Bottles, all of which will come into prominence in the movie.]]

* HeroicSacrifice: [[spoiler:Admittedly, hero is a stretch for Fu, but he manages to save Ryuuga from a deadly Rider Kick at the cost of his own life.]]
* KarmicDeath: [[spoiler: After all the evil stuff that Nanba has done over the series (and even before the series), it is no surprise that he would get his LaserGuidedKarma and be executed by Evolt the same way he had Prime Minister Mido killed.]]
* KilledOffForReal: [[spoiler: Fu and Rai Washio, as well as Jusaburo Nanba]].
* SanitySlippage: Utsumi seems to have lost some of his marbles near the end, and when he becomes [[spoiler:Kamen Rider Mad Rogue]], he goes LaughingMad.

* VillainousBreakdown: After seeing Evolt come into his office for the kill, Nanba basically [[AintTooProudtoBeg begs for his life]], even offering Nanba Heavy Industries to him. [[spoiler:It doesn't work out]].

** Evolt stalks Utsumi the entire episode trying to get Utsumi on his side. [[spoiler: Utsumi completely disregards the safety of the rest of the world once he processes that Juzaburo Nanba, the man who put him in his caged life, has been killed and immediately switches sides as he is rechristened as Kamen Rider Mad Rogue.]]
** As is mentioned in above tropes, [[spoiler: Fu and Rai Washio are both killed in battle by Evolt's Black Hole form and Nanba is killed like a fly after [[VillainsWantMercy begging Evolt to not kill him in exchange for his money or his company]].]]
