Black Woz

"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! (insert name here) Armor!"

- Woz's announcement of Zi-O.

The Mysterious Prophet Woz (謎の予言者ウォズ), alternatively spelt Wars, later referred to as Black Woz (黑ウォズ) by Sougo to differentiate him from his alternative self, 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).

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.

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.

Obtaining Fourze's Power
Woz appearing before Sougo as the latter was chasing Yamabuki Karin. Sougo the proceed to ask Woz if the Another Riders are behind the incident, which Woz affirms, but he later admits that he didn't really know the details. However, Woz tells Sougo that the incident starts with 'Shooting Star' before disappearing once more.

Obtaining Faiz's Power
Woz was mentioned by Sougo as Kusaka explained his motives and the origin of Ryuichi Sakuma and Yamabuki Karin. Sougo realizes that 'Shooting Star' is actually Ryusei Academy, which Tsukuyomi affirms

Obtaining Wizard's Power
Woz saves Geiz from falling down to his death by Schwarz's powers, but Geiz refused being saved by him, despite how they've known each other as "old friends".

Personality
Woz proudly supports Sougo as the identity of Oma Zi-O, assisting him as much as he can, however 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, even showing signs of skepticism of the boy's intention to change 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.

Woz has shown that he will do anything to make sure Sougo stays on the path of becoming Oma Zi-O. After believing Sougo has strayed too far from that path, Woz is more than willing to team up with the Time Jackers in order to get him back onto said path.

Woz is also shown to be paranoid besides concerning Sougo's well-being and keeping him on the path of Oma Zi-O, but also when it comes to changing the course of history and its future events, as shown when he confronts his future self from a different future where his master is dethroned. He is even appalled at his alternate self's smug and condescending attitude. On a funnier note, Woz gets agitated easily whenever Sougo purposely questions his identity as either Black or White Woz, since they're easily differentiatable.

Whenever Sougo obtains a new Rider Armor, Woz will say a speech. 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: (insert name here) Armor! (祝え！全ライダーの力を受け継ぎ、時空を超え過去と未来をしろしめす時の王者. その名も仮面ライダージオウ(...)アーマー!) Woz seems to be pleased whenever Sougo wants to hear Woz say his speech.

Relationships

 * Sougo Tokiwa/Kamen Rider Zi-O: Black Woz is the zealous believer of Oma Zi-O. As he believed Sougo to be the evil Oma Zi-O, Woz helps Sougo in his journey to becoming a demon king, even giving the Ziku Driver to show his support. He was surprised to hear that Sougo wanted to be a benevolent ruler but still chose to follow him anyway. He refers Sougo as My lord (我が魔王). While in return, Sougo is baffled due to Woz always appearing from nowhere, even when he was on different Timeline without apparent use of Time Mazine. Eventually, Sougo became used to Black Woz’s appearances and even casually greeting him. However, due to Sougo continually acting as he pleases and incidentally, straying from his path as Oma Zi-O, Black Woz secretly sided with the Time Jackers to "correct" his master. Although, his loyalty remains unnerved.
 * Geiz Myoukouin/Kamen Rider Geiz: Woz and Geiz known each other as "old friends". As Sworz used his power to cause Geiz to fall, Woz saved him.
 * Tsukuyomi: Tsukuyomi previously knew Woz, but not a lot of details are explored as of this moment.

Time Jackers

 * Sworz: Though he sees Sworz and the rest of the Time Jackers as a threat to his future master, Woz is willing to bargain with him to ensure that Geiz doesn't get in their way. After he becomes fed up with Sougo acting against his wishes, Woz is more willing to ally himself with Sworz and his gang to get him back to his path as Oma Zi-O.
 * Ora
 * Uhr

Legend Riders

 * Tsukasa Kadoya/Kamen Rider Decade: It is implied Woz knows Tsukasa because of his knowledge of Kamen Riders that come before his master. Woz even pointed out the similarities between the Destroyer of Worlds and his master.

Other

 * White Woz/Kamen Rider Woz: His alternate self from a future where Oma Zi-O is defeated. Woz himself found out that his alternate counterpart is the exact opposite of him, in that this Woz swore his loyalty to Geiz, to whom he referred to as his savior much like how the original Woz is loyal to Sougo, and by extension, Oma Zi-O. Black Woz later grews slightly paranoid to White Woz as White Woz steadfastly led the future for himself, and usually advised Sougo to not play into White Woz’s palm.

Portrayal
Woz is portrayed by Keisuke Watanabe (渡邊 圭祐), which now becomes a dual role due to portraying his alternate self.
