Alpha Tempus(Time Turner)

The Mysterious Prophet Tempus, or simply Tempus, is a zealous supporter of Samuel Thomas who travels from 2068 to 2018 in order to help him achieve his destiny and become the king known as King Time Turner. Later, as he engages in a rivalry with his Beta counterpart from an alternate future, he manages to steal the powers of Power Rider Film from Beta Tempus. He is named Alpha Tempus (黑ウォズ) until when Beta Tempus vanishes from existence. He is also the main narrator in the series.

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

Tempus would appear once again during Samuel's first encounter with Alter DNA, as he would encourage Samuel to transform into Time Turner, before entrusting him with the Time Spinner on a red velvet cushion for him to transform upon his acceptance, albeit with a surprised look on his face after Samuel's declaration to become 'the greatest and kindest one'. After his transformation, he would announce Samuel's first transformation into Time Turner. He would disappear during Time Turner's fight with Alter DNA mysteriously.

Tempus would appear once again to Samuel, after his narrow escape from Rewrite, which would greatly startle the future monarch. He would then reveal his identity to Samuel, proclaiming that he is an ally, and that he is trying to ensure Samuel's rise to King Time Turner. He then says that in the future, Samuel would be crowned the 'time king' through military conquest using the power of Time Turner. He would then warn Samuel of the Chrono Hackers, and their plan to bring forth a different king to usurp Time Turner. Then, he would once again disappear, indicated by the chime from the clock shop.

He would once again appear, this time inside Samuel's home, to inform him regarding the circumstances of Alter DNA. He reveals that due to the Chrono Hackers' history alteration, Alter DNA is now considered to be the real Power Rider DNA. He then reveals that Samuel will be unable to defeat Alter DNA even while Rewrite combats him.

Tempus would once again appear during Samuel's contemplation regarding the usage of the DNA Power Watch, with Samuel shocked by his sudden presence in 2017.

"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.

"Rejoice! He is the symbol of the new Reiwa Era! And his name is Kamen Rider Zero-One!"

- Black Woz's announcement about Sougo's successor

Sougo's Transformation into Ohma Zi-O
"My lord..." "Woz, rejoice." "Huh?" "I said rejoice!" "Rejoice! The Ultimate Time King who reaches over the space and time, and reigns over the past and future. His name is Ohma Zi-O! We are now reaching the last page of history itself!"

- Black Woz's announcement after Sougo embraces his destiny as Ohma Zi-O Fighting together with Kamen Rider Geiz, Kamen Rider Decade, and even Kamen Rider Diend, Woz was defeated by Another Decade and the kaijin he summoned, but was saved from death by the arrival of his lord, Sougo Tokiwa.

When Sougo ultimately transformed into Ohma Zi-O, Woz was surprised, as he had thought Sougo would never accept that power. However, upon being commanded to rejoice, Woz gave a speech to commemorate the birth of Ohma Zi-O.

After the final battle was over, Woz congratulated Sougo on his victory, and once again pledged his loyalty to Sougo Tokiwa. However, Sougo said that, because he felt he could not rule without friends, if not for Geiz & Tsukuyomi, he was going to destroy the current timeline, and allow a new one to be born in its place.

In the new timeline, Woz, observing Sougo's interactions with Geiz, Tsukuyomi, Heure, and Ora, noted that in this new timeline, a new history, different from what was in the pages of the Oma Advent Calendar, would need to be scribed.

Personality
Woz proudly supports Sougo's path to becoming Ohma 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 Ohma 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 Ohma 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.

Woz' cunning tactic is deemed great by his former Quartzer comrade and the original Sougo Tokiwa. As the series progress, Woz somehow prefer to be with the current Sougo Tokiwa instead of the original one despite his original mission to have Sougo become an Ohma Zi-O as a facade of the original Sougo's plan to change the new era. Woz' loyalty to the new Sougo is shown to the limit of breaking the set Ohma Advent from the original Sougo and somehow obtained the new one to lead the current Sougo's life.

On a funnier note, Woz is shown to have an obsessive side, especially regarding anything having to do with Ohma 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!).

If the events of Sougo being able to achieve a new form is not expected by himself, his speeches would be shown with confusion such as Trinity and Sougo finally accepting himself to become Ohma Zi-O (Woz had prepared for the outcome of Sougo not becoming Ohma because he has accepted Sougo as what he is as long as he became a Demon King). His speeches are generally liked by Sougo, even asking for one after his transformation into GaimArmor and Ohma Zi-O, and leaving good comments for his speech for 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.

Woz is also shown to possess good life skills like cooking and laundry.

 * 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 Ohma Zi-O. As he believed Sougo to be the evil Ohma 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 Ohma 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. But, it is revealed that Woz's loyalty is to the real Sougo Tokiwa, the founder and leader of Quartzer from another timeline. After seeing the Zi-O timeline's Sougo obtain the power of Ohma Zi-O as Zi-O Ohma Form however, Woz renounced his loyalty and membership of Quartzer, now fully supporting this Sougo.
 * 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 Ohma Zi-O and kill him. However, for some reason, Black Woz betrayed them and sided with Ohma 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 Ohma Zi-O and kill him. However, for some reason, Black Woz betrayed them and sided with Ohma 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.
 * Junichiro Tokiwa: Woz had a taste for Junichiro's food.

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 Ohma Zi-O. Nowadays Woz opposes Swartz openly because his ambition to become King.
 * 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 Ohma 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:
 * Tomizo Todayama/Kamen Rider Todoroki: Sougo sent Woz to Todoroki to learn about the Oni organization.

Other

 * White Woz/Kamen Rider Woz: His alternate self from a future where Ohma 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, Ohma 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.

Quartzer

 * Leader of Quartzer: Woz is actually a fervent member of Quartzer. The leader sent Woz to Zi-O's timeline with the Oma Advent Calendar to ensure his counterpart in that timeline become Ohma Zi-O. When Sougo and the other Quartzer come to Zi-O's own timeline, Woz quickly sides with them.

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.

Meme
Whenever Sougo and Woz himself assumed a new form, Woz would chant Rejoice! (祝え！) The Iwae proclamation soon became a common caption for any good news related to the Kamen Rider series, as well as a sarcastic comment on any joke on Woz himself.
