This article is about a/an episode in Kamen Rider Build.

The Final Revolution (終末のレボリューション Shūmatsu no Reboryūshon) is the fortieth episode of Kamen Rider Build. It features:

  • The full debut of Build Genius Form after its brief appearance at the end of the previous episode.
  • The return of the Dragon Sclashjelly since its destruction in Episode 30
  • The return of the Clone Smash since their last appearance in Episode 36
  • The return of Yoshiko Tajimi since her last appearance in Episode 22


The memories of Katsuragi were able to bring back Sento! Katsuragi succeeded in creating the Genius Fullbottle, also known as “The Ultimate Fullbottle”, which concentrates the essences of all 60 Fullbottles into the Build System! However, Build Genius Form did not awaken immediately. It was Sento’s feelings through his days using the Build System that were able to come together and bring forth the Build Genius transformation! Evolto however did not expect the creation of Build Genius, but he has begun to enter the final stages of his plan. Evolto attacks Kazumi and steals the Hokuto Trio’s Lost Fullbottles!
