"Rejoice! The one to inherit all Rider powers, the King of time who will rule over the past and the future. And his name is Kamen Rider Zi-O!"

The Mysterious Prophet Woz (謎の予言者ウォズ Nazo no Yogen-sha Wozu), alternatively spelt Wars[1], is a zealous supporter of Oma Zi-O from 2068 who travels back in time to 2018 and assists Sougo Tokiwa in order to help him become Oma Zi-O.

He will later transform into Kamen Rider Woz (仮面ライダーウォズ Kamen Raidā Wozu).[2]


The birth of Zi-O

Woz appeared before Sougo in anticipation of his first transformation into Zi-O, congratulating him and warning him vaguely of Geiz's Time Mazine before disappearing. When Sougo encountered Another Build, Woz appeared again to encourage Sougo to transform into Zi-O, providing him with the Ziku-Driver. Kingdom 2068

Obtaining Build's Power

Woz once again appears after Sougo's narrow escape from Geiz, which greatly startled the future monarch. Woz reveals that Sougo eventually rises to become King through military conquest using the power of Zi-O. He proclaims that he is Sougo's ally and that all his efforts will be toward keeping Sougo on the path to become the demon king. He warns Sougo of the Time Jackers and their aim to raise a new king to usurp Zi-O. However, Woz immediately disappears after giving this warning.

Woz appears again in Sougo's home to inform him of the circumstances of Another Build. He reveals that due to the Time Jackers' alteration of history, the kaijin is now considered the true Kamen Rider Build. He also informs Sougo that even though he is destined to be king, he is unable to defeat Another Build even while Geiz combats him.

Woz appears during Sougo's contemplation of using the Build Ridewatch, with Sougo confused at his presence in the year 2017. He tells Sougo that by using the Ridewatch, he accepts inheriting the power of Kamen Rider Build. He asks if he is willing to accept the responsibility of that power to which Sougo replies with an enthusiastic affirmative. After Sougo dons the Build Armor, Woz joyfully announces his king's inheritance of his first Rider power.

Woz appearing before Sougo as the latter was chasing Yamabuki Karin.

Obtaining OOO's power


Woz proudly supports Sougo as the identity of Oma Zi-O, assisting him as much as he can. His motivations for doing so are unknown. He will also go in lengths to protect Sougo, as demonstrated when he appeared and attacked Another Fourze.

While Geiz and Tsukuyomi are very wary of his presence, it also shows that Woz is trying to manipulate Sougo into becoming Oma Zi-O. He even shows signs of skepticism of the boy's intention of changing his destiny. Woz also shows strong distaste towards other people other than his master who proclaim themselves to be kings who abuse their power, such as in the case of Kuroto Dan who used the power of Another OOO to declare war against the world.
