History WMG / KamenRiderBuild

* Mossed. [[It's owner, however, is.]]

** Jossed; RabbitRabbit and TankTank don't utilize anything that relates to the number 10.

** And [[spoiler:confirmed for Evol, sort of: Isurugi was possessed by the Martian being Evolto when he was on Mars; Evolto has been the real Blood Stalk all along, and is now becoming Kamen Rider Evol.]]

*** This is jossed as the man that touched Pandora Box is [[spoiler:the owner of nascita, Soichi Isurugi, whilst possessed by Evolto]].

** Jossed. As of Episode 36, the highest Hazard Level that has been recorded with Sento is [[spoiler:6.3]], and even that was because of [[spoiler:his usage of the Pandora panel against Evolto]].

* Jossed. Proven by #33 where Soichi/[[spoiler: Evolto]] transforms into [[spoiler: Kamen Rider Evol (Cobra Form)]]

** Confirmed but the details are Jossed[[spoiler:with Shinobu Katsuragi being the second Build]]

* Jossed.

* Confirmed. [[The pandora's box is technically his.]]

[[WMG: Sento Kiryu is Takumi Katsuragi and completely unrelated to Sato Taro aside from face]]
* Night Rogue needed Katsuragi out of the way when he took over Faust, but also needed his intellect and scientific knowledge. That led to Katsuragi becoming a test subject and then left on the street for Souichi to find so he could become Build and continue to work on the development of the Rider System. Katsuragi's murder was faked as to make him disappear. Sato Taro was the unlucky dude that got picked up as the 'corpse' part of the process. Blood Stalk switched their faces for this, which is the reason why Night Rogue is still willing to work with him.

** Ha! StrangeMindsThinkAlike !
** Thirded. I think he was a clone. Perhaps even Night Rogue's clone...

*** This is jossed as the man that touched Pandora Box is [[spoiler: is the owner of nascita, Souichi Isurugi]].
** [[spoiler: Completely jossed by the revelation that Sento is Katsuragi. No more Specter RE:BIRTH.]]

[[WMG: Build's Hazard Levels]]

** Jossed. As noted by Stalk, Sento's Hazard Level after constant usage of the Hazard Trigger has become 4.2, before quickly rising up to 4.4.

[[WMG: Sento is Takumi Katsuragi in Taro Sato's body]]
A messy idiot comes into contact with a genius physicist that may have discovered the Nebula Gas's properties to undergo drug trials, the physicist is found dead, and the messy idiot is found an amnesiac genius physicist that's been exposed to Nebula Gas? That can't be a coincidence.
* OP again with an expansion on this theory: Either Katsuragi wasn't a founder of Faust or Night Rogue wanted to take his place as the leader of it, but either way Night Rogue out of the picture. He knew too much, and Katsuragi knew Rogue would put a hit on him because of it. To preserve himself he lured in Taro Sato and somehow swapped bodies with him just in the nick of time. Taro in Katsuragi's body was murdered, leaving Katsuragi in Taro's body as a witness to the murder. He was then kidnapped and exposed to the SMASH essence, but was most likely beaten by Soichi and woke up an amnesiac, leaving us with Sento.
* This is likely correct. In episode 8, Sentou is eating Mrs. Katsuragi's tamagoyaki and ''crying''. Previously, Ryuuga said that the tamagoyaki is too sweet, so it's ''unlikely'' that Sento is crying because it's not good. This is likely because Takumi's mind are reacting to his mom's comfort food.

* To add on, we know what kind of a person Sento was previously, yet he is now a brilliant scientist? Katsuragi's hidden files also indicate Project Build, coupled with Sento specifically mentioning that he created the Build Driver, this is more likely the case.

** [[spoiler: #15 confirms that Sento is Katsuragi so it might actually be like this.]]
** [[spoiler: #16 confirms that Sento is Katsuragi with Sato Taro's face.]]

[[WMG: Sento is a fusion between Tarou Satou and Takumi Katsuragi]]

* Jossed [[spoiler:by episode 16]].

*** Heisei Generations FINAL has confirmed that it was [[spoiler: Takumi as Build who took away Ex-Aid's power]], however #15 confirmed [[spoiler: Takumi IS Sento.]]
*** [[spoiler: Episode 34 confirms that he was the original Build when he tried to transform into GorillaMond]]

** Jossed. [[spoiler: There can't be two Builds, because they are the same person.]]

* Night Rogue needed Katsuragi out of the way when he took over Faust, but also needed his intellect and scientific knowledge. That led to Katsuragi becoming a test subject and then left on the street for Souichi to find so he could become Build and continue to work on the development of the Rider System. Katsuragi's murder was faked as to make him disappear. Sato Taro was unlucky dude that got picked up as the 'corpse' part of the process. Blood Stalk switched their faces for this, which is the reason why Night Rogue is still willing to work with him.

** As of now, its unconfirmed, and jossed.

** Jossed by #6. Sento was exposed to Smash essence, but did not turn into one.

[[WMG Everyone that Evolt kills in his Black hole form is JustHiding.]]

** Jossed, [[spoiler:but the final form does have an AllYourPowersCombined thing going on]].

* I felt that his personality undergo a change between his pre 'death' and afterwards. My theory is that Stalk influencing him, similar to people being exposed to Pandora's box light that made him more evil than he was before.

It seems that what the first Evol bottle becomes is determined by who Evolt is possessing (Souichi = Cobra; [[spoiler: Ryuga]] = Dragon; [[spoiler: Sento]] = Rabbit), and given that there hasn't been an Evolt Crocodile or Robot form revealed, that eliminates the possibility of him possessing Gentoku or Kazumi, Vernage currently occupies Misora, and I doubt Evolt would possess Sawa, Nanba, or Utsumi[[note]]and the Washio Bros are likely going to die, considering a), they're SoLastSeason, and b), Evolt practically has no use for them; it's only a matter of who will kill them[[/note]], so unless they introduce an entirely new character, that only leaves Evolt returning to Souichi as the only way that Evolt could access his Black Hole form.

[[WMG: Blood Stalk is grooming Ryuga to become the next body for Evol to posses]]
* #31 shows there ''is'' [[spoiler: something of Evol's power in Ryuga]] and Blood Stalk uses it to create the Magma [=FullBottle=].
