- "I care not about your opinion."
- ―Swartz when asserting his dominance[src]
Swartz (スウォルツ Suworutsu), alternatively spelled Suworutsu or Schwartz is the main antagonist of Kamen Rider Zi-O. He is the leader of the Time Jackers and the older brother to Tsukuyomi. After being rejected from being chosen as the next heir to a royal family in favor of his sister, he erases her memories and takes her and himself to a different timeline. From then on, Swartz has been instigating a series of events in order to fulfill his own agenda as King and is also responsible for the rise of Oma Zi-O.
Hailing from an alternate timeline, Swartz is the older of two children in a royal family, with a younger sister named Alpina. Due to unknown circumstances and despite that Swartz possesses greater power, Alpina is chosen as successor to the throne. Consumed by jealousy, Swartz erases Alpina's memories and transports her to the year 2068 of Oma Zi-O's timeline where she is eventually found by the Resistance. From this point on, Swarts began to formulate a scheme to achieve kingship which involved using someone "worthy" enough to retrieve the powers of the Kamen Riders and taking the powers for himself.
The Fateful Bus Accident
For the first phase of his plan, Swartz began to find that "worthy" person. Traveling to April 24, 2009, Swartz boarded a tour bus full of people (which is coincidentally driven by Tsukasa Kadoya) who are on a school field trip. Swartz targeted this bus in particular because all of the children aboard (including Sougo Tokiwa and Hiryu Kakogawa) were born in the year 2000. Swartz stops time and gets on the bus, causing Tsukasa to lose control. Swartz then states that the event is a trial for the children inside, whom he deems eligible to become future kings. Sougo's father, along with another father, stands up to Swartz, but they are swiftly pushed aside by his power. A young Sougo also summons the courage to fight against the Time Jacker, but to no avail. Swartz lifts the boy up and threatens him. At the same time, a time-traveling Tsukuyomi makes her presence known to Swartz as she shoots her Faizphone X gun at him in order to protect the young boy. Swartz uses his hat to block the shot, and then pushes Tsukuyomi away, saying that she was an "uninvited passenger". Swartz later teleports the children to a time/place where the world is being destroyed by Dai Mazines, leaving the adults to die as the bus crashes.
- "Little boy...You were born to be a King. You will become a King and are destined to save the world from destruction."
- ―Swartz planting the idea of kingship into a young Sougo Tokiwa[src]
As the Dai Mazines are destroying the children's surroundings, Swartz tells the children that only the future king can survive the event. Rubble is about to hit Hiryu, but Sougo, not wanting him to get hurt, awakens his powers, stops time and saves him from the falling rubble. Right after that, Sougo uses his sheer will to make a Dai Mazine turn into dust. Witnessing Sougo's potential, Swartz appears next to him and says to the boy that it was his destiny from birth to become a king and save the world. He then alters Sougo's mind, making him think that the entire ordeal is just a dream. In the process, he also bestows his time manipulation power unto the young boy. This explains Sougo's "childhood dream" of a man in black, saying he would definitely become a king in the future. Swartz then transports all the children back to the scene of the bus crash, apparently making it look like a normal traffic accident.
Another Fourze/Another Faiz
In the present, Swartz first appears during the case of Ryusei High School. He talks to his subordinates for a short moment, offering some chocolate to Heure (in a condescending manner) before leaving. He is responsible for making Ryuichi Sakuma (who, at that point, has already had the power of Another Faiz thanks to Ora earlier) become Another Fourze. As Ryuichi's Another Faiz powers start to fade away gradually, Swartz offers him the chance to become Another Fourze, so that he may still be able to save his girlfriend. Ryuichi is perfectly willing to accept the deal.
During the Another Wizard incident, Geiz Myokoin, on the way to deal with the threat, unexpectedly encounter the Time Jacker on the top of a building. Swartz attempts to take Geiz out by pushing him out of the rooftop and letting him fall to his death. Luckily for Geiz, Woz arrives just in time and saves him from Swartz. The Time Jacker is surprised the two become allies, then remarks that the arrival of Woz is not within calculation. He promptly takes his leave without causing further trouble.
Swartz has a brief talk with Heure and Ora, after the fall of Another Wizard. He says that Zi-O can become the King because he believes in his ambition, and never once doubts his ambition. This prompts Heure to search for the ideal candidate for Another OOO, a man who also never once doubts his ambition: Kuroto Dan, who is originally Kamen Rider Genm.
As Geiz decides to detach from Sougo and kill him for the sake of the future, after witnessing his actions in the OOO tribute arc, Swartz invites the Kamen Rider to join the Time Jackers in overthrowing Zi-O. Geiz states that he just wants to save the future from the tyranny of Oma Zi-O, but Swartz reminds him of his defeat at the hands of Sougo earlier, and suggests that Geiz should accept their invitation. Swartz takes Geiz's silence as a "yes". Swartz allows Geiz to see his newest creation: Another Gaim. He thinks that with the power of Kamen Rider and Another Rider combined, Zi-O will definitely be defeated. However, as Another Gaim starts attacking bystanders, Geiz jumps out and saves them from it, realizing that he can never join the Time Jackers due to their disregard for human life. Swartz leaves the scene, disappointed, as he previously thinks Geiz was "more intelligent".
Meanwhile, Woz, seeing that his master has messed up the timeline quite a bit by time travelling, decides to side himself with Swartz in order to get him back on to the path of becoming Oma Zi-O. He provides the Time Jacker with the information on Sougo's plan to acquire the Gaim Ridewatch. When Sougo is about to use it, Swartz appears right behind him. Sougo shoots him, but he stops the bullets midair and bounces them back at Zi-O. Swartz then takes the Ridewatch and throws it into Helheim forest. However, Sougo is still able to gain the Watch and defeat the Another Rider.
After the fall of Another Gaim, Woz comes to find Swartz and the gang again at a coffee restaurant, offering his assistance so that he may lead Sougo back on the path of becoming Oma Zi-O. He provides them with information on the Destroyer of Worlds, who can be a threat to his King: Tsukasa Kadoya. For a short while, Tsukasa joins the Time Jackers and fights Zi-O. However, it is later revealed that Tsukasa's main goal is to stop Oma Zi-O himself, and that he never intends to side with Swartz to begin with.
After the defeat of Another Ghost, Swartz notes that Oma's Day is coming even earlier than originally expected. He wonders whether Zi-O is aware of the Time Jackers' interference.
A new timeline
When Sougo has finally met his future self, he becomes terrified of what he might become, so he destroys his Ziku-Driver. Due to this act, the Time Jackers are free to do as they want. However, Swartz wants to remove everything that still has the potential to cause them harm, so he reactivates and brainwashes Oma Zi-O's then-inactive servant, Kasshin, to kill Sougo for good. Fortunately, Geiz and Tsukuyomi arrive in time to save Sougo and convince him to take up arms once again. Sougo agrees, but his actions cause the existence of a new timeline where Zi-O is defeated for good by Geiz.
At the start of the new year, 2019, Swartz is seen with his subordinates, who ask him what to do from then on. Swartz is aware of the changes in the original timeline caused by Sougo's earlier actions, saying that the changes might be beneficial to them. He then hands Heure the Another Shinobi Ridewatch as a "New Year's gift". Heure would later use it on Rentaro Kagura.
Due to the aforementioned changes in the timeline, another Woz, dressed in white, arrives from the future where Oma Zi-O does not exist. He swears loyalty to Geiz, saying that Geiz is the one who will defeat Zi-O and bring about his future instead of the original future where Oma Zi-O is supposed to rule with an iron fist. He transforms into Kamen Rider Woz and defeats Another Shinobi. Swartz seems to have expected this Woz's arrival, and reactivates the Another Shinobi Ridewatch.
Later that night, Swartz meets a distraught Rentaro, telling him not to worry, as the Riders have no way to obtain the corresponding Ridewatch to defeat him, as Kamen Rider Shinobi is technically not even born yet. However, Rentaro asks Swartz whether he can really use this power to protect the weak or not. Swartz's only response is that Rentaro, at the time, is basically invincible.
The next day, as Another Shinobi wreaks havoc, White Woz comes and sees Swartz. Swartz notes that it is impossible for the former to acquire Shinobi's powers because of the reasons mentioned above. White Woz does not waver, and he suggests asking Oma Zi-O. Zi-O faces and defeats Another Shinobi once again that day, but Swartz states that his effort is useles as he reactivates the Watch again. However, after the third defeat, Rentaro begins to resist Swartz's attempt at transforming him, thanks to Zi-O's encouragement. Swartz still forces the watch on him anyway. Nevertheless, White Woz has managed to create the Shinobi Miridewatch, much to Swartz's surprise. Another Shinobi is finally defeated for good by Kamen Rider Woz.
As Another Quiz is defeated at the hands of the Riders, Swartz tells Heure that White Woz's appearance has caused them a lot of trouble lately, while Heure keeps throwing a rock at a mirror again and again using his time-stopping and reversal powers. Swartz gets agitated, then asks what the young Time Jacker is doing. He says that he is trying to unlock the Mirror World from the information that Tsukasa has given him earlier. Heure meets Dark Shinji inside the Mirror World, and offers him the Another Ryuga Ridewatch.
When Another Kikai appears in the city, the Time Jackers do not know where or when it comes from. Swartz intends to harvest its powers, by turning it into an Anotherwatch. As Zi-O destroys Another Kikai for the second time, Swartz catches the "bug", which is the catalyst for its power, and forces it onto Heure, so that he may be able to gain an Anotherwatch later. He even challenges the Riders to create the Kikai Miridewatch before he does. The Riders eventually harvest the Kikai Miridewatch successfully, and manage to destroy Another Kikai once and for all.
With the three Miridewatches at hand, White Woz has finally been able to create the Geiz Revive Ridewacth for his savior. Swartz notes to Heure and Ora that Regulus (the "Star of kingship") will be at its brightest at the end of April, and that Oma's Day is coming closer and closer. Swartz decides to create Another Zi-O by using the Zi-O Anotherwatch on Hiryu Kakogawa, the child from the bus accident back in 2000. Apparently, Hiryu does not know the truth behind the accident, and he assumes that Sougo is the reason why his parents are dead. This action makes Heure extremely concerned, and starts to think that Swartz may have a hidden agenda.
Swartz later meets White Woz, who has lost his Kamen Rider power to Black Woz, stating that the Oma's Day that he wants to bring about will not be likely to occur. White Woz compliments Swartz on his "craftiness", and everything will eventually be in Swartz's favor in the long run. White Woz also notes that he needs to follow the Time Jacker's actions closely from that time on. Swartz only replies that he does not ask for White Woz's opinion.
On another morning, Swartz allows White Woz, now an ally, to use the Another Blade Ridewatch freely. However, he also notes to Woz that, to a human, there are ones who make use of power and ones who are used by power. The former group will think about righteous purposes, and the latter group will fail to understand their own purposes in life. Swartz wonders which group White Woz belongs to. After the defeat of Another Blade, Swartz and his two subordinates are seen in a coffee shop, with Heure wondering what Swartz has been up to all this time. Swartz takes no notice of his opinion, only remarking that it is inevitable to collect more Ridewatches, as Sougo Tokiwa has already experienced Oma's Day and is still on his way to become a King. Ora responds that Swartz's words do not sound pleasant at all, but Swartz assures that a plan is in motion at the time.
As Another Agitos are assauting the G3 team, Swartz stands on the sideline, and watches the whole event happen. When Tsukuyomi is about to be hit by one of the Another Agitos, she manages to inexplicably freeze time to stop the monster in the air, much to Swartz's surprise and bewilderment. Swartz then decides to "test" Tsukuyomi once again.
Swartz approaches Tsukuyomi as the latter is sitting on a bench. He asks whether the young girl is feeling anxious because of her power. Tsukuyomi says it is none of the Time Jacker's concern. However, Swartz reaffirms that it is indeed his concern, because he has taken his time to come and test her. Just as he finishes, an Another Agito appears and forces Tsukuyomi to run. Swartz wants the girl to show him her power again. He asks for her real name, as "Tsukuyomi" is just an alias, but she has no clue because she has lost her memory. Swartz remarks it would be better if she does not remember her past, as she would be happier that way.
When Shouichi Tsugami comes to save a cornered Tsukuyomi, Swartz compliments him on his performance as Kamen Rider Agito, but he also reveals that he has created the Another Agitos in order to be able to harvest the power of the original Agito by force. He then orders the Another Agitos to attack Shouichi. Shouichi transforms into Agito Storm and Flame Form and manages to gain the upper hand. However, Ora and Heure interrupt and hold Tsukuyomi hostage. Agito is then distracted, and knocked down by an Another Agito. Swartz says he did not ask for his subordinates' support, only for them to reply that Swartz's plan is not very effective in the first place. After Heure steals the power of Agito and creates an Agito Ridewatch, Tsukuyomi accidentally stops time once again, freezing everyone, including Swartz, much to the villain's bewilderment. Heure still manages to take the power of Agito and leaves with it. Tsukuyomi wants to know whether Swartz is aware of her past or not. Swartz does not respond and silently exits the scene with Ora.
Later, as hordes and hordes of Another Agitos are terrorizing the city, Woz comes and talks to Swartz about Tsukuyomi's time powers. He asks whether the Time Jacker wants to turn the young girl into one of them, to which Swartz replies that he has nothing to do with the matter. Woz knows that the time manipulation ability originally belongs to Swartz, and only he can bestow such a power on someone else. Swartz affirms this, hinting that Tsukuyomi and him may be from "the same group".
After the birth of Another Kiva, who starts to disobey Ora, Swartz is seen eating ice cream with Heure, commenting on Yuko's ferocity with amusement. This does not last long, however, when he is alarmed of the advent of a new and formidable foe from space: Kamen Rider Ginga. When Zi-O Trinity is utterly defeated by the space Rider's overwhelming power, Swartz suggests that the protagonists team up with him, because Ginga's presence is a huge hindrance to both sides. However, he secretly plans to take Ginga's powers for himself. The group then goes to Yuko for extra assistance. Swartz compliments Yuko on her looks, and even politely addresses her with honourifics. Yuko agrees to help defeat Ginga on one condition: Everyone must kneel before her. Swartz complies, and even forces Ora to kneel with him and Heure. Nevertheless, Yuko decides not to help anyway and leaves. Swartz angrily asks whether she knows how severe the situation is, only for Yuko to say that she does not care for his opinion, much to the Time Jacker's shock. Heure is amused at how his senior's words are thrown right back at him.
During the battle with Ginga, the Time Jackers offer support by providing cover fire. Swartz and Woz manage to land two hits on Ginga, just as dark clouds start to emerge. Ginga, being powered by the sun, is turned into stone and immobilized. As the clouds clear, Ginga returns to action, overpowering Swartz, Woz, Geiz Revive and Zi-O II simultaneously. Yuko finally decides to step in and help at this point, but she is also no match for Ginga's might. However, she is able to distract him long enough to create an opening for a triple Rider Kick. Ginga flees into space, and some of the Rider's essence manifests itself in the form of a Miridewatch, which lands on Swartz’s hand. Woz, having anticipated this all along, swiftly takes the Ginga Watch and escapes to fight Another Kiva, leaving Swartz agitated.
As the Worms are beginning to terrorize the city, Tsukuyomi uses her time powers to save a mother and her child from some falling rubble. Swartz stands on top of a building and observes, noting that her power is becoming more powerful, and that her "awakening" is just a matter of time. Tsukasa Kadoya suddenly makes his presence known to Swartz, asking what the Time Jacker really means by "awakening". Swartz even dares Tsukasa to "keep playing detective", to which the Rider responds that he certainly will find out the relationship between Swartz and Tsukuyomi.
Swartz appears before the duo when they are in the year 2058 searching for the truth, and knocks out an untransformed Tsukasa, while giving back Tsukuyomi the Fourze and Ginga Ridewatches (both of which have previously been stolen with the help of Another Kabuto). He tells Tsukuyomi to come back to the current timeline to help Sougo and Woz destroy the gigantic meteorite which is about to crash into Earth, as the Time Jackers do not wish for the Earth to be destroyed. He notes when the King of Time's power and her power unite, a brand new era is able to begin. As he returns to the current timeline, he sees that the meteorite is just another test for Tsukuyomi to awaken her true power.
Another Zi-O II
After Zi-O successfully obtains the power of all the previous main Heisei Kamen Riders, Swartz chooses not to play around anymore and starts to heavily tamper with the timeline, resulting in a new one where everybody (but Woz, the Time Jackers, Hiryu Kakogawa, Daiki Kaito and Tsukasa Kadoya) has lost their memories about Sougo. This timeline is ruled with an iron fist by none other than Hiryu Kakogawa himself, complete with a new and improved power set in the form of the Another Zi-O II Watch. He entrusts Ora with the duty of standing by the new King.
Daiki Kaito sees the new and chaotic timeline as an opportunity for him to steal more treasures, so he breaks into Hiryu's castle and steals the Another Zi-O II watch from him. Just as he is about to escape, Swartz stops time then returns the Watch to Hiryu. He ensures Hiryu that he can be counted on to deal with matters other than destroying Zi-O. After Hiryu and Ora leave, Swartz brainwashes Daiki and gives him time powers, telling the intruder that he has an even better treasure for him to steal. This later proves to be true, as Daiki is able to easily steal the GrandZi-O Ridewatch with his new time powers bestowed upon by Swartz.
- "Don't be afraid. I just want to ask you a few things... My dear little sister."
- ―Swartz reveals his relationship to Tsukuyomi in person[src]
As Zi-O II, without access to his final form, Sougo fights a hopeless battle against Another Zi-O II, Geiz deciding to step in and save Zi-O, taking him away from the battle. Swartz mockingly asks Hiryu whether he has lost to Zi-O. Hiryu justifies by pointing out that Sougo decided to run away, rather than continue the fight. Swartz pushes him further with his sarcastic questions, then he turns his eyes on Tsukuyomi, apparently having some plans to use her to his advantage. The girl realizes this and runs. Ultimately, Heure is able to catch Tsukuyomi and bring her back to Swartz. At the castle, Swartz reveals the fact that he and Tsukuyomi are siblings, much to both Heure and the girl's surprise and bewilderment.
Swartz soon exposes to her that they are both members of a royal family in an alternate timeline, that the time manipulation powers are a gift bestowed upon this royal family's bloodline, and that the "King"'s title will eventually belong upon him. Heure is shocked by this statement, because Time Jackers are supposed to dethrone Oma Zi-O rather than making someone among themselves the ruler. Swartz only smiles in response as he knocks Heure down. Just then, Ora also enters the room, asking why Daiki Kaito can use time powers. As she demands answers, the Time Jacker superior proceeds to take away her own powers, much to Heure's shock. Swartz discloses that he is the one who gives Heure and Ora powers in the first place, so naturally he is able to take it back as well. Heure, still appalled, grabs the Faizphone X and shoots Swartz, and manages to escape. Swartz tells Daiki to dispose of them, which he agrees to do.
Now that Swartz and Tsukuyomi are the only ones left, he continues to tell her about her past. He states that although his time power is the strongest in the family, Tsukuyomi is chosen to become the ruler instead of him, so he wipes his sister's memory and sends her to Oma Zi-O's timeline, hoping for her to get herself killed. In fact, he is surprised that his sister actually manages to survive until this day. Swartz attempts to take away Tsukuyomi's time power for himself, but Woz arrives in time to disrupt the process. However, Swartz knows from the start that Woz only follows Hiryu to spy on him, and subsequently knocks Woz crashing into a wall. Eventually, Swartz is able to absorb all of Tsukuyomi's powers into himself, becoming drastically more powerful as a result.
He is later seen observing Decade and Diend's battle. Just as Decade is about to finish Diend off, the latter stops time, freezing the former in place. Swartz pulls out a blank Anotherwatch and successfully takes away the power of Kamen Rider Decade.
After Sougo defeats Another Zi-O II and resets the timeline, Swartz allows Daiki to take the Another Zi-O II Watch as his treasure. He tells Hiryu that he has never had the qualities of a King to begin with. He also assures Tsukuyomi they will meet again and that he has taken Tsukasa's powers. With the Another Decade Watch in his possession, Swartz proclaims that his reign will finally begin.
Swartz makes his next move as he creates Another Drive and has it terrorize around the city. It is, however, defeated by Zi-O and Geiz, revealing Ora as the Another Rider's host. Heure expresses his confusion, as both him and her have agreed to conspire against their former leader earlier. Just then, Swartz appears and transforms into Another Decade. He uses a Dimensional Wall to transport Zi-O and Geiz to another world, where he summons Kamen Riders Rey, G4, Fuma and Dark Ghost to fight the duo. Swartz then proceeds to overpower them with his newfound power. However, Woz somehow manages to gain access into Swartz's world and is able to free the duo from the onslaught.
Later on, Swartz uses his power to make one of Sougo's friends-Owada, disappear, and he summons Katsumi Daido - Kemnen Rider Eternal to fight the young man. As Eternal gains the upper hand, Tsukasa appears, but Swartz is not concerned, as he has already stolen Decade's power. However, Tsukasa notes that his power is not only the power of Kamen Rider, but also his own existence itself. Then, Tsukasa quickly takes control of Swartz's Dimensional Wall and frees Zi-O from his fight with Eternal, surprising the Time Jacker.
Seeing that Tsukuyomi has to return to the future, Michal Minato - Kamen Rider Aqua - takes her to Swartz so that she can have a chance to take back her time power. However, he has to face Kamen Rider Eternal. As they battle, Aqua uses water to bind Swartz in place, creating an opening for Tsukuyomi to absorb his time power. Her effort proves to be futile when Swartz transforms into Another Decade, cancelling the absorption. Before he manages to harm the girl, Geiz shows up to defend her. Unfortunately, Swartz has planned his arrival, and he uses his power to trap Geiz inside his Another World. From the newly-formed Dimension Wall, the Time Jacker summons none other than White Woz, much to the shock of the girl. Black Woz also shows up to protect her, and manages to free her from Another Decade.
True goal and plans revealed
Swartz is still on his way to summon more villain Riders to aid him. This time, he is able to summon Kamen Rider Yuuki, by trapping a man named Yukihiro in his Another World. Later, Ora comes to meet him, proving to him that she has killed Heure. Swartz is amused by this, and he gives Ora her time power back.
Black Woz faces White Woz in battle, and the latter is thoroughly outclassed by the former's GingaFinaly form. Black Woz destroys White Woz with a Rider Kick, but Swartz appears and simply summons another White Woz from Another World. This White Woz uses the newly-formed Dimensional Wall to transport Black Woz and Tsukuyomi into Another World, where Geiz is being trapped. Zi-O, who is fighting Swartz's Yuuki at the time, is outraged by this and he attempts to strike the Time Jacker. Eternal interferes, and Swartz continues to mock Sougo that he will never see Black Woz and Tsukuyomi again. He leaves Zi-O to Eternal.
However, everything is just White Woz's plan to save Geiz - his "savior" - from Another World. Following his guidance, Zi-O is able to use Eternal's power to destroy several Another Worlds and free the people trapped inside, including Geiz. The Riders Swartz summons, Eternal and Yuuki, eventually disappear from reality as a result. White Woz intends to say something about Swartz's evil plan before he vanishes also, but he is destroyed prematurely by Swartz's energy blast before he can disclose anything to Sougo's group. The Time Jacker is annoyed at the fact that he has been tricked, but he also summons the other villain Riders whose Another Worlds have not yet been destroyed: G4, Fuuma, Dark Ghost and Rey. Geiz and Black Woz transform and engage the four of them, leaving Sougo alone with Swartz.
He asks whether the young man wants to fight, now that they are all alone. Sougo replies that he is not alone, and Aqua appears from behind Swartz to strike. However, Swartz is also not without allies, as Ora makes her presence known and uses her power to freeze both Aqua and Sougo in place. At this point, Swartz finally reveals to Sougo that he is the "man in black" in Sougo's childhood dreams, the one responsible for plating the idea of becoming a King and saving the world into his head, and that he is also the culprit behind the bus accident and all the events that follow on April 24, 2009. Sougo is appalled by the revelation, not knowing why Swartz would do that. He replies that he has been watching Sougo's steps since day one, and he has actually helped Sougo to collect the power of the Heisei Kamen Riders by creating corresponding Another Riders for him to fight. Now that Sougo's power is at its peak, Swartz intends to steal that power so that he can become the King in his place.
- "You have collected the power of a great number of Kamen Riders. Now, let me keep that power for you...so that I can become the King! "
- ―Swartz reveals his true intention to Sougo
After all that revelation of his schemes, Swartz is frozen in time by Ora. It turns out that Ora only feigns her allegiance to the Time Jacker so that she can kill him if the chance comes. She now knows his ultimate purpose and prepares to kill him for vengeance. Nevertheless, Swartz easily breaks free from being frozen, having already anticipated Ora's backstabbing. He transforms into Another Decade and kills Ora effortlessly with a simple kick to the head, even sarcastically wishing her and Heure a "happy life in hell".
As Ora is dead, Sougo is freed from being frozen as well, remarking that Swartz is not fit to become a King. The latter assures him that he has enough power to rule over all. Sougo retorts that a King's power is supposed to make the world a better place. He transforms into GrandZi-O and attacks Another Decade in anger.
The two fight to a standstill. Swartz tells Sougo that if he defeats and kills him, his timeline will cease to exist, which also means that Tsukuyomi will cease to exist along with him. He tells the young Rider that there is only one way that she can be allowed to keep living. In the middle of the explanation, Aqua comes to Sougo's aid and prepares a Rider Kick aimed at Another Decade. Unfortunately, Another Decade is able to easily counterattack with the power of a Dimensional Wall and a Rider Kick. The force of his Rider Kick is powerful enough to kill Aqua and knock GrandZi-O out of his transformation.
- "Now, you only have three choices. One for Tsukuyomi's sake, one for your own sake, and one is...to become Oma Zi-O!... "
- ―Swartz on the choices that Sougo has to take [src]
Sougo mourns the death of Minato, the latter disclosing Tsukuyomi's real name "Alpina" to him before his passing. Swartz informs Sougo that he only has three choices at the time: Let Swartz take his power, and Tsukuyomi will get to live for the time being, but Swartz will rule the world; or kill Swartz and let Tsukuyomi be erased along with him for good; or let the original future take its course - Sougo becomes Oma Zi-O and rules the world with an iron fist just like he is destined to be. The young Rider, devastated, can do nothing but scream Swartz's name in grief and anger. The Time Jacker even notes that Sougo does not have much time left to decide on his options, as the Sky Wall suddenly appears before his eyes. The Guardians and Smash also appear along with the Wall, and they start terrorizing the city.
It is revealed that the situation at hand is because of Sougo's Ridewatches (the Build Ridewatch in particular) cracking. The Drive Ridewatch also cracks some time later, releasing the Roidmudes into the world. Swartz notes in the middle of the chaos that everything is up to Sougo's decision now.
His younger self in 2058
- "Only the strong can become King! I will become King!"
- ―2058 Swartz on his ideaology[src]
Tsukuyomi intends to kill the young Swartz in the year 2058 to end the trouble before it starts, but she is ultimately unable to pull the trigger. Swartz fires an energy blast, also with the intention to kill the girl, only for Tsukasa to step in and take the blast for her, killing himself as a result.
Just then, Daiki Kaito also arrives at 2058 via a Dimensional Wall. The young Swartz retreats after dodging a few shots of his Neo Diendriver. Tsukasa is later revived by Daiki's Another Zi-O II Watch.
The Final Battle
Back in the present day, more and more monsters from various Kamen Rider series emerge and the world is on the verge of destruction. Geiz is trying his best to save as many people as he can. Amidst the chaos, Swartz shows up, transforms into Another Decade to challenge Geiz Revive to a battle. The two fight for a while before Tsukasa comes to help Geiz. In the middle of the fight, Geiz and Tsukasa note that Swartz's timeline will be saved from destruction, but not by Swartz, rather, by his sister Tsukuyomi. The Time Jacker is furious at this statement, and he proceeds to overpower both Geiz and Decade. He prepares a Rider Kick aimed at Geiz, but Geiz suddenly disappears (He is summoned by Zi-O Trinity), much to his surprise.
Tsukasa continues the battle, but Swartz stops time and freeze him in place, boasting about being the strongest. However, he is counterattacked by Diend, who has been given time powers by Swartz himself. Despite having to fight two on one, Another Decade still has the upper hand against Decade and Diend. He uses a Dimensional Wall to leave the scene, saying that he will erase Tsukuyomi, alerting Geiz (who has just returned after Zi-O Trinity detransforms).
As Mashin Chaser is chasing after Tsukuyomi, trying to kill her, Another Decade stops him, saying that he will finish the job himself. However, Chase suddenly gets in his way, having regained part of his heroic personality, and tries to fight him. Unfortunately, Mashin Chaser is no match for Another Decade, and Swartz kills him with a Rider Kick. With his obstacle gone, Swartz focuses on his sister again. Sougo runs towards the scene, telling Tsukuyomi to pull out her Ridewatch. It is revealed that Sougo has previously travelled to 2068 to give the Tsukuyomi there a blank Ridewatch. Now that the watch has been imbued with a part of Oma Zi-O's power, the present Tsukuyomi gains the power of a Kamen Rider herself. Woz throws her a Ziku-Driver, and she begins her transformation, much to the shock of Swartz.
Kamen Rider Zi-O NEXT TIME
To be added.
Of all the Time Jackers, Swartz is extremely cold and calculating, always having tricks up his sleeve. He is also very arrogant and does not leave room for anyone "lower than him" to express their opinion. At first, he appears to be solely motivated on creating the new King replacing Oma Zi-O in the future by creating Another Riders by force. Any Another Rider hosts are nothing but mere guinea pigs to him, and even Heure is no exception. As the series progresses, Swartz's actions makes it more and more evident that he is secretly preparing for a personal agenda, a fact that even the Time Jackers gradually and vaguely become aware of. This is even further affirmed by White Woz, who shortly before his disappearance has warned Sougo's team that Swartz is up to something dark. Eventually, it is revealed that Swartz wants to set himself up to be the new King, reclaiming the throne he has been denied from his royal family by amassing as much power as possible. Furthermore, by merging the Riders' worlds together, he is able to save his own timeline from destruction. Most of the events in the series is the result of Swartz's meticulous calculation: The Another Riders, for example, are purposely made for Zi-O to defeat so that he must gather the power of other Kamen Riders. When Zi-O has collected such power, Swartz will come in and steal his power at its most powerful state for himself. Also, the gathering of Ridewatches have made the merging of the timelines of other Kamen Riders complete, impeccably bringing Swartz's plan into effect.
Swartz is a no-nonsense, serious and ruthless man who is more than willing to go through extreme lengths to achieve his goals, even if it means hurting his allies, his own blood, and innocent people (including children). This is shown by his actions in 2009, where he sabotages the bus just to "test" the children and indoctrinate Sougo into becoming a king. He is cruel, heartless, and treacherous enough to betray and steal the powers of his own allies Heure and Ora, even making the Another Riders and Daiki Kaito go after them to kill them just to be certain. This is further extended to the point where he shows no remorse or guilt in hurting his own sister to get what he wants, and simply laughs in joy after he steals her powers. In fact, he is even slightly surprised when his sister does not get herself killed in Oma Zi-O's timeline. In yet another proof of how cruel he can be, he ends up killing Ora when she tries to kill him to survive, showing that for him to become king, he does not mind killing one of his own, a proof of his facinorous depravity.
On a couple of side notes, he becomes flabbergasted if someone with higher authority than him appears, and he does not mind allowing that person to voice out their opinion, much to Heure's amusement. In fact, he even politely addresses them with honourifics, and is perfectly willing to listen to their demands. The two prime examples of this are Yuko Kitajima and Hiryu Kakogawa (as Another Zi-O II). He shows no hesitation in obeying their commands, and doing their bidding, to the point of forcing his Time Jacker allies to comply with him (He forces Ora to kneel before Yuko along with him and Heure). However, all of this so-called "obedient" manners only last as long as the person(s) in question proves to be an asset for him to further his goals. The instant he sees them as expendable and hindering to his objectives, he returns to his cold, ruthless self, and is more than eager to discard them. This goes to show how tolerant Swartz can be to manipulate others for his own sake.
His evil intentions as well as his disapproval of Alpina being chosen instead of him has actually taken root since his teenaged years. By then he had already been mentally prepared to wipe her memories and dump her into an another timeline, when she began to pose a threat to his own ambitions. However, Swartz did not completely disregard Alpina's powers as he believes that if he can control them, it would prove beneficial for his plan to "save the world", though he is completely willing to kill her should she ultimately become an hindrance to his plans. This implies that despite his noble intention of saving his kind, he is rather selfish and only cares for his own well-being and no one else.
Swartz, while confident in his ability as a Time Jacker and schemer, is not beyond being cautious and vigilant. Whenever something that is not within his calculation appears (White Woz, Kamen Rider Ginga, Tsukuyomi's awakening time power, Tsukasa Kadoya), he would not take his chances with it hastily, but rather chooses to wait and see whether he can use such things to his own advantage. In fact, most of the times, he is successful at doing this, further emphasizing his cunningness. Despite this, Swartz is not without weaknesses, with his own hubris ultimately leading to his downfall -- to which his own sister taking advantage of his delusions of grandeur, allowing Sougo, as Oma Zi-O to defeat him once and for all.
Powers and Abilities
Initially, Swartz was never seen on how he fight in real battlefield and only attacks people from behind. He once attempted to kill Geiz by freezing time and to throw him off the cliff. He only shoot his opponents and never enter close combat fight which is normally done by the Time Jackers as they have neither the forms of a monster nor a Kamen Rider.
After becoming Another Decade, it is proven that he is a cheap fighter. Everytime his opponent is about to land a deadly blow, Swartz will always create a part or full scale of dimensional wall to teleport the blow, something that not even Tsukasa and Daiki do in their fight.
- Time Travel: He can freely travel back and forward in time. He can even travel to points in alternative timelines, which not even a Time Mazine could go to. Apparently, he does not seem to need a Time Mazine to do this, as shown when he teleports the children on the bus to another space/time.
- Temporal Awareness: He is the only one who somehow knows about GeizRevive's timeline and other ones.
- Time Manipulation: Being a member of the royal family, he possesses the innate power to stop the movements of everything around him. When this ability is on, he can, completely or partially, spare people of his choosing from its effect. He states that his time manipulation power is the strongest in his family.
- Power Bestowal: Swartz can bestow time manipulation powers to others through a painful method, albeit a weaker version of his own. It is unknown what happens to those powers whose users die (say, Heure).
- Power Absorbtion: Swartz can absorb time manipulation powers from any person who possesses them, like Ora and Tsukuyomi. Doing so also results in an exponential increase in his own powers.
- Memory Alteration: Swartz also has the ability to alter and or erase memories. He altered Sougo's memories in 2009 so that he'd only recall such an event as a dream. He also erased Tsukuyomi's memories before dumping her into a different timeline.
- AI Reactivating: Swartz demonstrates the ability to revive and put Kasshin under his control with a touch in the head in order to kill Sougo Tokiwa.
- Telekinesis: Swartz is also able to use telekinetic powers as means of offensive ability.
- Keen Manipulator: Over the course of the series, Swartz has proven himself to be more than capable as a schemer. In fact, a majority of the events that has happened in the series is the result of Swartz's manipulation so that he is able to crown himself as the new king.
- Tsukuyomi: Tsukuyomi is also a member of the royal family, her time manipulation ability can also stop Swartz in his tracks, something that Heure and Ora cannot do as they are not royalty since he has bestowed them these powers to begin with. Tsukuyomi also can steal time manipulation abilities from others as well, and can very well do it to Swartz.
- Tsukasa Kadoya: Whether contingent or precautionary, Tsukasa had partitioned half of his Rider Powers into the Decade Ridewatch before entrusting it to Sougo. This limited Swartz's control over Tsukasa's Rider powers when he stole them and also unknowingly established a remote connection with Tsukasa. This enabled Tsukasa to freely manipulate any active Dimensional Walls produced by Swartz and with greater skill.
- Oma Zi-O: Despite his formidable power after becoming Another Decade, Swartz's overall ability still pales in comparison to that of Sougo once the latter transforms into Oma Zi-O. This was shown during the final battle, as Sougo in Oma Zi-O form was able to easily break free from Another Decade's attempt to absorb Oma Zi-O's power and swiftly defeats the Another World villains (which includes N-Daguva-Zeba, Gamedeus and Kamen Rider Evol Cobra (Phase 1)) before overpowering and finishing Swartz off with a powerful Rider Kick.
- Egotism: This is Swartz's fatal flaw. Anyone who can play with his fantasies of being a king will be able to manipulate him into thinking they are on his side. Tsukuyomi has used that to successfully backstab him.

- Anotherwatch - Transformation trinket
- Heure: Swartz sees Heure as nothing but a mere child. He also does not mind using Heure to be the host of Another Kikai. After Swartz reveals his true intentions and takes Ora's powers, Heure begins to see Swartz as an enemy, vowing to get even with him for his manipulation.
- Ora: Ora sees Swartz as her superior, and shows some dislike towards him. On the other hand, Swartz allows Ora to do as she pleases, even going as far as to reuse Heure as Another Kikai's host. However, Ora is not beyond being spared by Swartz, as after he takes away her powers, he sent Another Riders and Diend to kill her and Heure. Ora comes to resent Swartz because of this, even returning the GrandZi-O Watch to Sougo to thwart Swartz's plan. She becomes one of his victims, because trying to kill him with her own hands, she ends up being murdered by him.
- Sougo Tokiwa/Kamen Rider Zi-O: Perhaps the biggest obstacle to him, he works to dethrone him. Despite this, it is revealed that Swartz is the one responsible for putting Sougo on the path to become a king. It is eventually revealed that he has purposely created enemies for Sougo to fight, just so that he can steal Sougo's power for himself when his power is at its peak. After Sougo learns about his malicious schemes, Swartz gives Sougo a triple-lose condition, prompting the former to consider him his primary enemy that he has to defeat at all costs.
- Geiz Myokoin: Briefly these two have the same goal and Swartz, along with Ora even invites Geiz to join Time Jackers. Thankfully, Geiz wises up and views the man as his enemy.
- Tsukuyomi: Tsukuyomi is Swartz's younger sister. Not much is known about their relationship in the past, though it is implied that they used to have a good relationship until some point. When Tsukuyomi is chosen to be the new ruler of their bloodline, Swartz's jealousy gets the better of him, and he erases Tsukuyomi's memories and sends her into a dystopian timeline, hoping that she will get herself killed there. However years later, Swartz is not aware that she has managed to survive until her powers reawakens. With Tsukuyomi unprepared to face the fact of their relationship, Swartz takes advantage of this and stripped her of her powers. Tsukuyomi genuinely desires to put a stop to her brother's evil schemes.
- (Black) Woz: Seeing the man as nothing more than a nuisance, Swartz does not care much about Woz, yet when he offers to help, if their goals are lined up similarly, he will work with the record keeper until their objectives are met. Woz is also seemingly the only one wise enough to be aware of Swartz's tricks up his sleeve, as shown when he steals the Ginga Watch from Swartz.
- Hiryu Kakogawa: Using him to try and destroy Sougo, Swartz creates Another Zi-O using a child from the bus incident that he himself caused, using his own hate and rage to control him. Hiryu is unaware of the fact that Swartz was the one who caused the accident that cost him his parents. In fact, Swartz only sees Hiryu as nothing but another means to an end. When he has outlived his usefulness, Swartz discards him at once, even allowing Diend to take away his Another Zi-O II Watch and mocking him for his failure, saying that he has never had any qualities of a King to begin with.
- (White) Woz: Swartz and White Woz joined forces in discreet after the latter loses his power as Kamen Rider Woz to his counterpart. Both are now hellbent to create a future they desire. However, after several repeated failures, Swartz gives White Woz one last chance and exclaim that whether he was using Swartz or being used by Swartz is up to him. Upon Zi-O acquiring the Zi-O Trinity Ridewatch from White Woz and he himself was about to be erased, he warns his counterpart about Swartz’s plan and to be cautious to him, effectively betraying Swartz.
Behind the Scenes
Swartz is portrayed by Kentaro Kanesaki (兼崎 健太郎 Kanesaki Kentarō).
- Swartz is a portmanteau of Swatch, a brand of Swiss watches, and quartz, the mineral used to regulate the electronic oscillator installed in clocks and watches.
- The existence of Another Decade was foreshadowed by the erection of his statue shown outside Another Zi-O II's residence.
- As with most Another Riders, Swartz as Another Decade is both opposite and similar to Tsukasa Kadoya in many ways:
- Both possess the ability to warp time and space; Tsukasa having the uncontrollable ability to merge the A.R. Worlds he travels to and Swartz altering the Kamen Riders' history by creating Another Riders whom he can control.
- Both are leaders of their season's evil organization. Tsukasa was formerly the Great Leader of Dai-Shocker and Swartz is the leader of the currently disbanded Time Jackers.
- While Tsukasa doesn't bother or is annoyed about people asking him about anything, Swartz is willing to silence anyone who questions him.
- Their roles towards Sougo also parallels each other. Tsukasa, initially an enemy to Sougo, was secretly trying to guide him to a better future, while Swartz was secretly trying to manipulate Sougo to become Oma Zi-O by creating Another Riders for Zi-O to defeat.
- Both have a younger sister who opposes them (Sayo Kadoya and Tsukuyomi), although Swartz is willing to hurt his sister for his own goals.
- Although Tsukasa unintentionally merged the A.R. Worlds into one world, Swartz is deliberately merging the A.R. Worlds for his own purposes.
- By extension, he is similar to Daiki Kaito as well. Both commit acts of thievery, mostly stealing a Rider's power. Both riders can summon past riders. Daiki also has a sibling who opposes him as well.
- Like Narutaki, Another Decade has the ability to summon Riders by shifting dimensions, either transporting them to the dimension where his targets are. Both share the ability to summon dark-type villain Riders who can be hostile enough to fight their opponents, but the difference is while the dark-type villain Riders summoned by Swartz become his loyal servants, those summoned by Narutaki have questionable loyalty.
- His demise also mirrors the way Tsukasa himself fell in Movie War 2010 , as both died in the "end" of their series by the hands of a Female Rider (Tsukasa by Kiva-la, Swartz by Tsukuyomi)
- Another Decade's demonic design refers to Tsukasa being called a "Devil" by the Decade cast several times.
- The legs of Another Decade resembles that of Decade Complete Form.
- The head of Another Decade resembles Decade's logo due to the barcode-like lines, as well as his eyes resembles the eyes of Decade Violent Emotion Form.
- Swartz is similar to the previous series main antagonist, Evolto due to being wirepullers behind most of the series' events.
- Swartz is the last Time Jacker to be killed.
