White Woz is a an alternate version of Woz originating from the alterations of the timeline made by the protagonists in Kamen Rider Zi-O. He has the power to transform into Kamen Rider Woz and is capable of using the powers of the future Kamen Riders of his timeline.

Origin
White Woz comes from an alternate timeline created as a result of Sougo breaking his Ziku Driver for the first time. In his timeline, on the Day of Oma when Sougo Tokiwa became Oma Zi-O he was defeated by Geiz Revive, resulting in a more peaceful timeline in which new Kamen Riders arose.

Present
White Woz travels to the present to ensure the existence of his own timeline by any means necessary. Arriving in 2019, Woz encountered Uhr and wrote in his notebook that Uhr would be in a "traffic accident", causing the car Another Shinobi to swerve towards Uhr. After Uhr stopped time to prevent himself from being hit, Woz asked him tell him everything about Another Shinobi. Uhr refused, so Woz wrote that Uhr's time power would unfreeze, causing the car to begin moving towards Uhr again. Uhr desperately attempted to freeze time again and became exhausted. As Uhr finally froze time once more, Woz again asked if Uhr would provide him with information about Another Shinobi. Uhr fianlly gives in and tells Woz that he knows nothing about that Another Rider and he only got its watch from Sworz. Satisfied with the information he had been given, Woz lets Uhr go and leaves.

Woz then finds Kamen Riders Zi-O and Geiz right after their fight with Another Shinobi and reveals himself to them after writing that Zi-O would fall off his bike., and Tsukuyomi quickly deduced that White Woz was a different Woz than the one they were acquainted with. After White Woz uses his book to screw with Zi-O some more, the original Woz shows up and asks his alternate self who he is. When White Woz instead recognizes that he is the one who serves Oma Zi-O, Woz teleports himself, Zi-O and Tsukuyomi away with his scarf. Annoyed that they ran away Woz writes in his notebook that Another Shinobi followed Geiz to Sougo, Tsukuyomi and his alternate counterpart.

White Woz then shows up in the warehouse where Zi-O and Geiz are fighting Another Shinobi. He uses his powers to make the warehouse disappear, leaving everyone out in the open. His alternate self asked him what he wants, to which White Woz reveals that he's after Another Shinobi's watch. White Woz then goes to Geiz and states he is his savior. As everyone stands confused by his statement, White Woz reveals that he is from a timeline where on Oma's Day, Geiz killed Oma Zi-O. Referring to Geiz as "Geiz Revive", White Woz tells everyone that he's come from his future to assist Geiz.

White Woz then summons his BeyonDriver and uses it to transform into Kamen Rider Woz. The Future Kamen Rider swiftly defeats Another Shinobi and reverts him back to his human form.

Personality
Unlike the original Woz who is rather polite and well-mannered at best, White Woz is rather smug, heartless, uncaring, and unscrupulous at worst. He enjoys flaunting his ability to control future events, to which he insistently refers to as "guiding" the future. While his prime counterpart and the Time Jackers possess a level of moral boundaries they would not cross, White Woz is utterly callous, sadistic and a downright sociopath even moreso than Sworz, as shown when he threatens Uhr by putting him into a car accident, pushing Ora out of the way on two occassion when she tries to protect Another Quiz. And lastly, mocking Tamotsu Douan/Another Quiz's efforts as in vain and reminding him that his own family too will leave him, all with a smile on his face. He, like Black Woz, can be manipulative if he wants to, especially towards Geiz. He went as far as to persuade Geiz into defeating Kamen Rider Quiz and take away his powers, and forcibly taking away the said Rider's powers in front of Geiz as an example to justify to him that he will become the savior who will defeat Oma Zi-O.

Trivia

 * White Woz's notebook having the ability to manipulate future events along with the actions of those names written on it is an allusion to the titular notebook from the Death Note anime/manga series.
