Black Woz

The Mysterious Prophet Woz (謎の予言者ウォズ), later known as Black Woz (黑ウォズ), and simply Woz (before White Woz's appearance and after his erasure) is a zealous supporter of Sougo Tokiwa who travels from 2068 to 2018 in order to help him achieve his destiny and become the demon king known as Oma Zi-O. Later, as he engages in a rivalry with his white counterpart from an alternate future, he manages to steal his alternate self's Rider powers with the help of Hiryu Kakogawa and Heure, and gains the ability to transform into Kamen Rider Woz (仮面ライダーウォズ). He is also the main narrator in the series.

Background
Woz is a member of Quartzer, as evident of his membership robes. He received the Oma Advent Calendar from his leader Sougo Tokiwa a book that detailed how his younger self became Oma Zi-O, and was tasked to ensure it stayed that way. To do so, he infiltrates the Resistance as a captain, with Geiz and Tsukuyomi as his underlings. By doing so, he gained the authority to act as their "spy" in order to get close to Oma Zi-O and commit his loyalty to him. Since then, he began feeding Oma Zi-O important Resistance information to allow the Demon King to exploit their weaknesses and destroy the Resistance, while feigning allegiance to the Resistance. With Geiz and Tsukuyomi being the only survivors, they became desperate and went back in time to 2018 to stop Sougo Tokiwa from becoming Oma Zi-O. Knowing this would severely jeopardize his own existence, Oma Zi-O sent Woz after them.

2018: Zi-O's Birth
Woz would appear before Sougo as he was heading back from his school, in anticipation of his first transformation into Zi-O, congratulating him, and vaguely warning him of the appearance of Geiz's Time Mazine before disappearing, indicated by the Sougo's bicycle bell ringing.

Woz would appear once again during Sougo's first encounter with Another Build, as he would encourage Sougo to transform into Zi-O, before entrusting him with the Ziku-Driver on a red velvet cushion for him to transform upon his acceptance, albeit with a surprised look on his face after Sougo's declaration to become 'the greatest and kindest demon king'. After his transformation, he would announce Sougo's first transformation into Zi-O. He would disappear during Zi-O's fight with Another Build mysteriously.

2017: Build's Power
Woz would appear once again to Sougo, after his narrow escape from Geiz, which would greatly startle the future monarch. He would then reveal his identity to Sougo, proclaiming that he is an ally, and that he is trying to ensure Sougo's rise to Oma Zi-O. He then says that in the future, Sougo would be crowned the 'time king' through military conquest using the power of Zi-O. He would then warn Sougo of the Time Jackers, and their plan to bring forth a different king to usurp Zi-O. Then, he would once again disappear, indicated by the chime from the clock shop.

He would once again appear, this time inside Sougo's home, to inform him regarding the circumstances of Another Build. He reveals that due to the Time Jackers' history alteration, Another Build is now considered to be the real Kamen Rider Build. He then reveals that Sougo will be unable to defeat Another Build even while Geiz combats him.

Woz would once again appear during Sougo's contemplation regarding the usage of the Build Ridewatch, with Sougo shocked by his sudden presence in 2017. He tells that Sougo by using the Ridewatch, he accepts inheriting the power of Build, and asks if he is willing to accept the responsibility. After Sougo would don BuildArmor, Woz would announce his king's inheritance of the first Rider power.

2018: Unbeatable Game
Woz would play a minor role in Ex-Aid arc, first appearing to Sougo as he would discover another victim of Another Ex-Aid's attacks. However, he would show mild discontent at Sougo's ignorance of him, before he would approach him, shocking the herald once again. He would then reveal the location of Seito University Hospital, the next location Sougo would need to head to to find answers.

2016: Ex-Aid's Power
Woz would once again appear to Sougo after he used the Time Mazine to travel to 2016, revealing that a Rider's power was required to defeat an Another Rider, after Sougo would notice Emu's attacks dealing damage to Another Ex-Aid. After Sougo would don Ex-AidArmor, Woz would also announce his transformation, screaming louder than the usual.

2011: Fourze's Power
Woz appeared in front of Sougo as the latter was chasing Karin Yamabuki who had ran out from Amanogawa High School, which surprised him greatly, prompting the herald to inform Sougo to 'get used to it'. Sougo would then ask Woz whether the 'missing girls' were related to an Another Rider, to Woz's affirmation. However, he would then admit that he did not really know the details, labeling the information as 'convoluted' before disappearing once more.

He would once again appear in 2011, blocking the attack of Another Fourze as Sougo was about to transform into Zi-O FourzeArmor, causing Sougo to enter a state of great surprise. Then, he would repel Another Fourze using a 'repelling' attack, to the surprise of Sougo and Geiz. Allowing Zi-O to transform, Sougo would don FourzeArmor, before Woz would announce his lord's newest form.

2003: Shooting Star
Woz would not play a direct role in the obtaining of the Faiz RideWatch, and subsequently, Geiz's transformation into FaizArmor. However, Woz would be mentioned by Sougo during Kusaka's explanation regarding his motives and the origins of Ryuichi and Karin, realizing that the 'shooting star' Woz meant was the Ryusei School, his statement affirmed by Tsukuyomi.

2012: 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".

Day of Oma=

2019: Another Ryuga
As Sougo goes to confront Shinji Kido about Another Ryuga, Woz appears before him. He says that Another Ryuga can be defeated easily using the Zi-O II Ridewatch, but Sougo refuses, as using the item will transforms him into Ohma Zi-O, exactly to Woz's plan.

2019: Zi-O II's Debut
After Geiz's death because Another Ryuga's reflected attack, Sougo appears and rewind the time to save him. He then transforms into Zi-O II as Woz, after some time, announces his Demon Lord's ascension. He then left Sougo to fight to his heart content.

2019: Kamen Rider Woz
"The power of Kamen Rider Woz...has indeed returned to Woz." "Why could you...?!" "Don't think you're the only Woz around here."

- Black Woz reprimands White Woz why he could steal his power. During the events of Another Zi-O's rise to power, Woz accompanied Sougo to try and protect Hayase, the former Another Wizard, explaining to Sougo that he has no clue who Sougo is due to Geiz beating him in 2012. Sougo tells Woz that he can relate to watching Hayase from afar like Geiz and Tsukuyomi did and wonders if they were as excited as he was. Woz then interjects by asking if he is excited to seek out the mysterious Another Rider to which he replies not that but to possibly see Geiz and Tsukuyomi again.

Eventually, the groups make contact with Hiryu Kakogawa and learn of his alternate identity as Another Zi-O. Woz then decides to look into the young man's name, having heard it somewhere before. This leads him to learn of the bus accident back in 2009 where he discovers that not only was Sougo and Hiryu on that bus, but also Tsukasa Kadoya.

After GeizRevive soundly defeats Zi-O II, he confronts Geiz and tries to defeat him, insisting for Zi-O II and GeizRevive to not battle each other more. But the power of GeizRevive was too great for him to handle by himself. To make things fair, Woz decides to conspires with Time Jackers. Although Ora refuses due to her traumatic experience with White Woz, Heure decides to ally himself with Black Woz discreetly. Both of them agreed to take White Woz's powers using Hiryu to ambush him. As Hiryu successfully steals his powers with a Blank Ridewatch, White Woz uses his notebook to try and take back his powers. However, because of his poor word choice, Black Woz managed to gain White Woz power and fled as White Woz screamed in anger. He then confronts Geiz again and transforms into Kamen Rider Woz and begins to fight after remarking this event.

However, despite his best efforts, Woz was still defeated by GeizRevive. Although, this is also part of Black Woz Plan to delay Geiz for battling with Sougo. Sometimes later, Black Woz decides to stay with Sougo, Geiz and Tsukuyomi in 9 5 DO and both Black Woz and Geiz hesitantly form a Truce.

Personality
Although his motivations for doing so are unknown, Woz proudly supports Sougo's path to becoming Oma Zi-O and will do anything to protect him and make sure he stays on that path, which includes teaming up with the enemy and manipulating him. 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. Woz also gets agitated easily whenever Sougo purposely questions his identity as either Black or White Woz, since they're easily differentiable.

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 skepticism signs 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.

On a funnier note, Woz is shown to have an obsessive side, especially regarding anything having to do with Oma Zi-O (i.e his birthday). Woz would go through extreme lengths to make sure Sougo's birthday is extravagant, such making his birthday cake while practicing his speech and even training with a Taiko along with Sougo and Geiz, since he misheard that said training will give a blessing to the practitioner. However, this obsessive side is a double-edged sword for him, as he will slump into a depression when he realizes his efforts are for naught. This is shown when Tsukuyomi ends up berating him, saying his efforts are merely amusing himself as opposed to Sougo, realizing he doesn't understand how to celebrate important events such as these.

Woz has also shown to have a sweet tooth, as he developed an immediate love for Junichiro's apple pies and asked for more, even taking a heartbroken Sougo's portion when he insists he didn't want any after Yuko Kitajima's death.

Whenever himself or an ally gains a new form, he will recite a commemorative speech. He does this on every occasion that Sougo receives a new Rider Armor which goes as:Rejoice! The one to inherit all Rider powers, the time king 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/仮面ライダージオウ(...)アーマー!). Woz's speeches are generally liked by Sougo, even asking for one after his transformation in Zi-O II, which pleased Woz a lot. However, he can still get annoyed if Woz delivers a speech during a battle in a tense mood, like what he began doing each time after Zi-OTrinity's debut.

He is also shown to possess good life skills like cooking.

Powers and Abilities

 * Time Travel: Woz possesses the ability to travel back and forth across the timeline. This often comes to the confusion of Sougo Tokiwa, as Woz tends to appear suddenly and without the apparent use of a Time Mazine.

 * Energy Attack: Woz has been shown to be able release an energy attack from his hand, which he uses to knock Another Fourze away from Sougo.
 * Flight: Woz possesses the ability to fly.
 * Fabrikinesis: Woz can manipulate his scarf through prehensile means as an offensive and defensive weapon.
 * Keen Manipulator: Woz is able to outsmart White Woz and take advantage of his Future Note by having him "give" Black Woz the Kamen Rider Woz powers. He also used the disadvantage of GeizRevive for at least weakening him further before Geiz was going to meet Sougo for a showdown.
 * Gaia Library access: Woz can somehow access the Gaia Library. According to a tweet by producer Shinichiro Shirakura, the Gaia Library that Woz accesses is pseudo and actually his own imagination
 * Knowledge of past Kamen Riders: Woz is one of the few people in his timeline to have knowledge of all the past Kamen Riders that come before Sougo.

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 to Sougo as My lord (我が魔王). Initially, 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; he is also shown to be intrigued by Sougo as time goes on, and eventually becomes supportive of Sougo's own goals to create a new future of his own.
 * Geiz Myokoin/Kamen Rider Geiz: Black Woz and Geiz are apparently "old friends", and are still acquainted enough to the point that Woz will still try to save Geiz from Swartz. However, as time goes on, he begins to doubt Geiz being by Sougo's side and tries to get rid of him but fails to do so. Once White Woz enters the fray, he begins to hesitant to be around Geiz and Tsukuyomi, knowing that they all share the same goal and thus leaves Sougo to his own devices unless his intervention is needed. It isn't until GeizRevive is created that Woz tries to defeat him but fails to do so not once but twice, even with the second fight having Woz use the power of Kamen Rider Woz. However, Woz seems to hold some respect for Geiz in the end as they all manage to tolerate one another after the Another Zi-O Incident. It is later revealed that Geiz and Tsukuyomi were once Resistance members under Black Woz, in order to spy on Oma Zi-O and kill him. However, for some reason, Black Woz betrayed them and sided with Oma Zi-O, resulting in the death of many of their comrades in battle. Geiz and Woz would later put aside their differences and reconcile their friendship after some instigation from Sougo, during the near-apocalypse triggered by Another Blade.
 * Tsukuyomi: Tsukuyomi and Black Woz are acquainted with each other, as evidenced by Tsukuyomi knowing his name when he appears in front of her and Sougo. It is later revealed that Tsukuyomi and Geiz were once Resistance members under Black Woz, in order to spy on Oma Zi-O and kill him. However, for some reason, Black Woz betrayed them and sided with Oma Zi-O, resulting in the death of many of their comrades in battle. Tsukuyomi still can't trust Black Woz but remained civil to him.

Time Jackers

 * Swartz: Though he sees Swartz 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 Swartz and his gang to get him back to his path as Oma Zi-O.
 * Ora: Ora didn't really trust either Black or White Woz, although she's more civil and reserved to the former Woz.
 * Heure: Heure originally shared the same distaste for Black Woz as the rest of the Time Jackers. However, after the appearance of White Woz (who almost killed Heure on one occasion), Heure softened slightly to Black Woz's presence. Furthermore, after the events of the Another Kikai incident (in which Ora and Swartz showed a willingness to use Heure as a puppet in their schemes), and the creation of Another Zi-O (a plan which Heure sees as just another path to the Oma Zi-O timeline), Heure begins to show doubt in the plans of the Time Jackers. As such, Heure allies himself with Black Woz against White Woz, allowing Black Woz to steal the powers of Kamen Rider Woz.

Legend Riders

 * Tsukasa Kadoya/Kamen Rider Decade: It is implied Woz knows Tsukasa because of his Kamen Rider knowledge that came before his master. Woz even pointed out the similarities between the World Destroyer and his master. He was later shocked after finding out Tsukasa's name is among those of who perished in the bus accident where Sougo's and Hiryu Kakogawa's parents died.
 * Daiki Kaito/Kamen Rider Diend:

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 grew slightly paranoid of White Woz, as White Woz steadfastly aims for his future, and usually advises Sougo not to play into White Woz’s palm. However, upon his apparent teamwork with Heure, Black Woz managed to steal White Woz's powers. Black Woz’s relationship with White Woz was resolved peacefully shortly before White Woz faded away.

Portrayal
Black Woz is portrayed by Keisuke Watanabe (渡邊 圭祐), who also portrays a dual-role with White Woz.

Etymology
Woz's name is a reference to, the co-founder of the computer company , which alludes to his smartwatch motif in his Rider form.
