|This article is about a/an event in Kamen Rider Zi-O.|
Oma Zi-O's timeline
On this day, Zi-O will transform into Oma Zi-O and control seven giant monstrous machines called Dai Mazines to destroy the world along with all Kamen Riders and become the "Demon King." This global catastrophe will create the dystopian timeline where Geiz Myoukouin, Tsukuyomi and the original Woz came from.
Geiz Revive's timeline
On this day, Geiz Revive will defeat Oma Zi-O and save the world, becoming its savior and creating a new history. Sometime after this day, Another Woz will travel to January 2019 to assist Geiz. This is also the timeline where future Kamen Riders Shinobi, Quiz and Kikai hail from.
