Swartz

This article is about a villain in Kamen Rider Zi-O.

Swartz (スウォルツ, Suworutsu)^[1] is the main antagonist of Kamen Rider Zi-O. He is the eldest member of a mysterious royal family from another timeline and the leader of the Time Jackers who transforms into Another Decade (アナザーディケイド, Anazā Dikeido), an Another Rider derived from Kamen Rider Decade.

History[]

Background[]

Swartz is a resident from an alternate timeline where he and his younger sister Alpina were members of a royal family with temporal abilities. Realizing their timeline was on the verge of destruction, Swartz sought to save his world which involves the power of Kamen Riders from other timelines. Before he could enact the plan, Alpina had been chosen as successor to the family throne for possessing greater power than him. Consumed by jealousy, Swartz had his sister's memories erased and left her stranded in the year 2068, where she is found by the Resistance.

On April 24, 2009, Swartz orchestrated a bus accident to abduct the children aboard and leaving the adults to die once the bus crashed into a tunnel. He later brought them to an alternate future where a city under attack by several Dai Mazines, challenging them to survive. After seeing Sougo Tokiwa saving Hiryu Kakogawa using his unconscious temporal abilities, Swartz foretold the young boy that it was his destiny to become king before using his powers to make Sougo believe the ordeal was a dream. He transports the young Sougo and Hiryu back to the site of the bus crash, making it look like a traffic accident.

Swartz eventually founded the Time Jackers and recruited Heure and Ora from different timelines. They traveled to different periods within the Heisei era and created Another Riders by taking away the Kamen Riders' powers and granting them to their contracts whom the Time Jackers will manipulate. While he led the accomplices to believe they are crowning a new ruler to replace Ohma Zi-O, Swartz's true intentions were to make Sougo Tokiwa stronger by collecting the Kamen Riders' powers and become the "King of Time" himself.

The History Heist[]

Swartz made his first presence in the year 2018, where he meets up with Heure and Ora by freezing them in frozen time. He picked up a chocolate candy from a passerby and mockingly offered it to Heure, treating him as a child before leaving. Swartz later becomes responsible for the creations of Another Faiz and Another Gaim. He acknowledges how Ohma Zi-O succeeded in ruling over time is because he always believed his ambitions, never doubting his right as king.

When Geiz Myokoin became more distant with Sougo Tokiwa, Swartz tried to recruit Geiz seeing how he wants to save the future from Ohma Zi-O's tyranny. Much to Swartz's disappointment, Geiz remained steadfast to fight the Time Jackers due to their disregard towards the innocent bystanders harmed by the Another Riders. Meanwhile, Woz begins to collude with Swartz and the Time Jackers, and through him recuits the Destroyer of Worlds, Tsukasa Kadoya to their cause.

Following Sougo Tokiwa's decision to give up the Ziku-Driver after his encounter with his future self, the Time Jackers were free to do whatever the desired. However, Swartz planned to have Sougo eliminated to ensure nothing will disrupt the Time Jackers' intentions. Swartz reactivates and brainwashes Kasshine to kill Sougo, only for Geiz and Tsukuyomi to arrive and convince Sougo to become Zi-O once more. However, the decision for Sougo to temporarily give up the Ziku-Driver began to diverge the timeline to new outcomes.

The Divergent Paths[]

After the new year had begun, Swartz and the Time Jackers became aware that the original timeline had changed caused by Sougo's actions. He remarked that despite this, it could be beneficial to them. Swartz led the Time Jackers to create Another Riders based on the Future Kamen Riders. In addition to the changes to the timeline, it also manifested another Woz, aptly to referred as White Woz, who recovers their powers as Kamen Rider Woz.

Swartz became responsible for the creation of Another Shinobi and forces Rentaro Kagura to become the Another Rider, before he was completely defeated by White Woz using the Shinobi Miridewatch. When Another Kikai made his mysterious emergence, Swartz intends to harvest its powers by forcing its power onto Heure. He even challenges the Riders to create the Kikai Miridewatch before he does. White Woz eventually harvest the Kikai Miridewatch successfully, and manage to destroy Another Kikai once and for all.

As Oma's Day was approaching, Swartz decided to create Another Zi-O and chose the host to be Hiryu Kakogawa, the other child who survived the bus accident back in 2009. Hiryu does not know the truth behind the accident, and he assumed 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. It is also around this time when Tsukuyomi and Tsukasa Kadoya discovered Swartz's involvement of the bus accident that killed Sougo and Hiryu's parents which resulted in Sougo's childhood nightmares.

After White Woz lost his powers and loses his faith with Geiz, Swartz began to collaborate with him. The next morning, he passes an Anotherwatch for White Woz to create Another Blade. He remarks to White Woz that to human, there are those who make use of power and those who are used by power. Another Blade would be defeated by the arrival of Kamen Rider Zi-OTrinity and White Woz is erased from the timeline, not before warning Black Woz to be wary of Swartz.

The Grand Obstacle[]

During Sougo's quest to gather the remaining Ridewatches, Swartz and the other Time Jackers continued to gather the Kamen Riders' powers to create Another Riders. But instead of stealing and erasing the Kamen Riders' powers, they instead replicated their powers from present day to create Another Riders in 2019 instead. Swartz was responsible for the creation for Another Agito and became aware of Tsukuyomi's sudden temporal abilities. When Woz confronted him about her abilities, Swartz cryptically hinted a connection between the two of them.

As the Worms are beginning to terrorize the city, Tsukuyomi uses her temporal abilities to save a mother and child from falling rubble. Swartz observes her and notes that her power is becoming more powerful. When she and Tsukasa Kadoya investigated her past, Swartz arrived to the year 2058 to force them back to 2019 by giving them the stolen Fourze and Ginga Watches to stop an incoming meteorite. Swartz remarks and confirmed to himself that Tsukuyomi is indeed his younger sister. He sees that the meteorite is just another test for Tsukuyomi to awaken her true power.

Eventually, Sougo managed to acquire the nineteen Ridewatches, resulting in the creation of the GrandZi-O Ridewatch and the presence of Kamen Rider GrandZ-O. Although this appeared to be a major setback on the Time Jacker's side, this became a victory on Swartz's side as he somewhat succeeded in having Sougo gather the powers of all the Heisei Kamen Riders, for him to take away one day.

The Time-Space Conspiracy[]

Sometime after Sougo acquired the power of GrandZi-O, Swartz contracts with Hiryu Kakogawa once more to become Another Zi-O II, creating a reality where he ruled the world with an iron fist. When Daiki Kaito broke into Hiryu's castle, Swartz grants him the ability to stop time for his services. After having Tsukuyomi captured, he revealed to her that they are siblings and their family heritage. Swartz showcased his true colors by trying to take Heure, Ora, and Tsukuyomi's powers for himself. When Kamen Rider Decade engaged the Another Rider army, he took the opportunity to rob Tsukasa of his powers and abandons Hiryu believing he served his purpose. With the Decade Anotherwatch in his possession, Swartz proclaims his reign will finally begin.

With Kamen Rider Decade's powers in his hands, Swartz was granted access with the Another Worlds by trapping civilian victims in a neverending loop as a means to revive the Dark Riders. He also recruits the Paradox Roidmude to become Another Drive with the task to dispose Heure and Ora. Swartz showcases his transformation into Another Decade and becomes a formidable opponent to the Kamen Riders. After murdering Ora and Michal Minato, Swartz reveals to Sougo that he is the one who imparted his dream to become king. He also gave Sougo the three impossible choices to either defeat him and let Tsukuyomi be erased from existence, let Swartz take his powers, or let history take course and become Ohma Zi-O.

Meanwhile, elements connected to the previous Heisei Riders began to emerge, and monsters started appearing all over the city. While investigating, the heroes discovered Swartz's true agenda and how he had groomed Sougo as a catalyst to gather the Kamen Riders' powers for Swartz himself. As the world teetered on the brink of destruction, the Kamen Riders set out to save the residents while facing the dilemma of Swartz and Tsukuyomi's homeworld. Although the plan aimed for Tsukuyomi to become a Kamen Rider to bridge both worlds, Kamen Rider Tsukuyomi unexpectedly aligns herself with Swartz, musing the Time Jacker indeed.

Final Battle and Death[]

With his homeworld safe from destruction and Tsukuyomi at his side, Swartz proceeded to unleash destruction. Another Decade led his army of villains against the Kamen Riders, gaining the upper hand against GrandZi-O. While unleashing a deadly attack on Sougo, Geiz sacrificed himself to shield against the onslaught. Sougo, enraged by the sacrifice, transformed into Ohma Zi-O, much to Swartz's delight, who anticipated absorbing his powers. However, Swartz underestimated the overwhelming power of the Demon King, who possessed the combined abilities of every Kamen Rider. Another Decade found himself overwhelmed and attempted to escape, only to be attacked by Tsukuyomi from behind. In retaliation for his sister's obliteration, Sougo, now as Ohma Zi-O, became further enraged, leading to Another Decade's ultimate demise. Ultimately, Sougo chose to wield Ohma Zi-O's power to rewrite the world's history, restoring it to twenty Earths and undoing Swartz's actions for good.

Other Events[]

Kamen Rider Zi-O NEXT TIME: Geiz, Majesty[]

Continued after Ohma Zi-O's reverting the Rider timelines back to normal, Swartz was revealed to be alive in the new timeline as the ordinary principal of Hikarigamori High School. He visits with the Geiz of the new timeline and talks to him about his aspirations in the future. He also starts having private conversation with Heure and Ora that were still unknown. Upon learning Geiz's aspirations of being a savior, he begins to chuckle. It is implied that even in the reset timeline, Swartz still has memories of his previous life.

Rider Time: Kamen Rider Zi-O VS Decade -7 of Zi-O!-[]

When Hikarigamori High School was brought into an alternate dimension, Swartz found himself and his students trapped in this new realm which is surrounded by Elementary Inves. Swartz has forbidden anyone from leaving the school to preserve their own safety. Swartz is worried the rest of the school cannot stand hunger for more extended periods. He then tells the students to try enjoying school life because that is the only way to survive together in such a situation and even help open a school romance club.

After meeting with different versions of Sougo Tokiwa, Swartz organized a competition among all the Sougos to select the worthy one to become class president. Due to the shortage of food on campus, Swartz decides to cook Inves meat for the school. Sougo A is horrified by this at first, but ends up helping Swartz with his cooking. When Heure is dragged by Sougo C into the ground, Ora shows up to protect him from the Inves, accidentally wiping them out in the process. Swartz, having seen everything, notes that Ora is finally beginning to remember her power.

As more Sougo Tokiwas show up at school, Swartz invites them to join the race for student president. The following day, when Inves outside invade the school, Swartz fends off some monsters to protect his students. At the same time, a child identifies himself as Ohma Zi-O, who has become weakened due to having destroyed and created too many worlds. Swartz arrives and reveals Sougo A is the winner of the student president position. As a massive battle breaks out, and Swartz joins the fray to help Sougo as Another Decade. After Sougo manages to defeat Ohma Zi-O, the world returns to normal. Swartz and Ora were part ways, with the former saying they will meet Heure again, who had been killed by Ohma Zi-O prior.

Personality[]

Zi-O series[]

Swartz is known for his cold and calculated nature, always harboring hidden schemes. He exhibits arrogance, dismissing opinions from those he considers beneath him. Initially focused on creating Another Riders to replace Ohma Zi-O, he treats hosts as mere guinea pigs. As the series progresses, Swartz's personal agenda becomes evident, even to other Time Jackers. White Woz warns of his dark intentions before disappearing. Swartz ultimately seeks to reclaim a denied throne by becoming the new King, using the merging of Riders' worlds to save his timeline. Many events in the series result from Swartz's calculated actions, such as creating Another Riders for Zi-O to defeat, compelling him to gather power from other Kamen Riders. Swartz plans to steal Zi-O's power at its peak, and the collection of Ridewatches contributes to successfully merging other Kamen Riders' timelines, executing his plan flawlessly.

He is characterized by a no-nonsense and ruthless demeanor. Swartz is willing to go to extreme lengths to achieve his goals, even if it involves harming allies, family, and innocent people, including children. Notably, in 2009, he sabotages a bus to test and indoctrinate Sougo into becoming a king. Swartz displays cruelty and treachery by betraying and stealing powers from his own allies, Heure and Ora. He orchestrates the creation of Another Riders and manipulates Daiki Kaito to pursue and kill Heure and Ora. Swartz shows a complete lack of remorse or guilt when hurting his own sister and laughs joyfully after stealing her powers. His callous nature extends to the point of killing Ora when she attempts to survive by attacking him, showcasing his willingness to eliminate his own allies for his ambition, demonstrating dark and morally depravity.

Swartz can be taken aback when confronted with figures of higher authority, but he's quick to adapt, showing deference and complying with their wishes. This is evident in his interactions with characters like Yuko Kitajima and Hiryu Kakogawa (as Another Zi-O II). However, his compliance is conditional, as he only follows orders as long as it serves his goals. Once he deems them expendable, he returns to his ruthless self, shedding any pretense of obedience. This reveals Swartz's manipulative nature, adept at exploiting situations to his advantage.

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 Ohma Zi-O to defeat him once and for all.

Zi-O Aftermath[]

After he had been defeated by Zi-O, Swartz remained his cold persona and intimidation. Although, he has become much warmer and enjoys more of his current life, even he has discarded his goal to become the new king. Swartz even gives more care towards anyone he is in responsible for, either as a principal or the leader of Time Jacker. No longer antagonizing Sougo and Tsukuyomi, Swartz has started a new journey to be a savior for various worlds.

Powers and Abilities[]

Powers[]

• Time Travel: Swartz is the only Time Jacker with the natural ability to 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 Absorption: 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 Kasshine 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.

Abilities[]

• Expert Tactician: Swartz never engages in close quarters combat and often resorts to unfair tactics, which at one point included freezing time and attempting to throw Geiz off a cliff. After becoming Another Decade, Swartz continued using unfair tactics. Every time 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 would do.
• Expert 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.

Weaknesses[]

• Tsukuyomi: Tsukuyomi is also a member of the royal family, her time manipulation abilities rivals Swartz, 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.
• Daiki Kaito: Like Tsukuyomi, Swartz is also vulnerable to his Time Stop ability (although, it was almost weaker) after he bestowed him with his power.
• 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 Aurora Curtains produced by Swartz and with greater skill.

Forms[]

• Rider Height: 192 cm^[2]
• Rider Weight: 83 kg^[2]
• Creator: Himself
• Year of Origin: 2019
• Position of year: Right Pectoral (Underneath Name)
• Name and position: "DECADE"; Right Pectoral (Above Year).

Powers and Abilities

• World Creation: Another Decade's existence brings forth the materialization of the World of Lost Possibilities known as Another Worlds, a world under Another Decade's control with an army of Dark Riders that follow his will^[2].
• Summoning: Another Decade can summon Dark Riders from his Another World. They're copies of their counterparts from the main universe, but loyal to him. Another Decade can also summon the final villains of different Kamen Riders. Like the Dark Riders, they are loyal to him.
• Dimensional Teleportation: Another Decade can teleport themself and their opponent to a random location of their choosing using Aurora Curtains.
• Strong Resistance: Another Decade's armor is strong enough to block most attacks, such as Geiz Revive Goretsu's Zikan Zaclaw. He is even able to (at least) defend against Ohma Zi-O's Ohma Zi-O Hisatssu Geki, whereas other monster simply destroyed within one hit.
• Dimension Kick: Another Decade is capable of executing a Rider Kick based on Kamen Rider Decade's Dimension Kick. The kick is powerful enough to kill an armored warrior, such as Kamen Rider Aqua and Mashin Chaser, with the resulting explosion strong enough to knock Sougo out of his GrandZi-O form.
• Dimension Blast: Another Decade can be able to generate a purple energy ball that is powerful enough to crack Geiz's helmet open and mortally wound him.
• Rider Punch: Another Decade uses a Rider Punch based on Kamen Rider Decade's Dimension Punch. However, the force of his punch was backfired by the initial Ohma Zi-O's Ohma Zi-O Hissatsu Geki.

Equipment[]

• Anotherwatch - Transformation trinket

Family[]

• (Kamen Rider) Tsukuyomi/Alpina: Tsukuyomi / Alpina 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 she will get killed. However years later, Swartz is unaware that she had managed to survive until her powers reawaken. With Tsukuyomi unprepared to face the facts of their relationship, Swartz takes advantage of this and strips her of her powers. Tsukuyomi genuinely desires to put a stop to her brother's evil schemes, to the point of feigning loyalty, only to backstab him in the end. With the death of Swartz, Tsukuyomi also disappeared, but she's revived thanks to Sougo's use of Ohma Zi-O's power.

Relationships[]

Time Jackers:[]

• 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.

Enemies:[]

• Sougo Tokiwa/Kamen Rider Zi-O: Perhaps the biggest obstacle to him, he works to dethrone him. Despite this, 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. In the end, by killing both Geiz and Tsukuyomi, an enraged Sougo embraces his destiny as Ohma Zi-O and successfully killed him.
• Geiz Myokoin/Kamen Rider Geiz: Originally these two have the same goal and Swartz, along with Ora, even invites Geiz to join the Time Jackers. Thankfully, Geiz wises up and views the man as his enemy.
• (Black) Woz/Kamen Rider 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, as shown when he steals the Ginga Watch from Swartz before the latter could make use of it.

Others:[]

• Hiryu Kakogawa/Another Zi-O (II): 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-OTrinity 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[]

Portrayal[]

Swartz is portrayed by Kentaro Kanesaki (兼崎 健太郎, Kanesaki Kentarō). As Another Decade, his suit actor is Jiro Okamoto (岡元 次郎, Okamoto Jirō).

Etymology[]

• 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.
• Swartz is also referring to Aaron Swartz, a well-known computer scientist, in the same way Woz is referring Steve Wozniak.

Concept Art[]

Another Decade was designed by Tamotsu Shinohara (篠原 保, Shinohara Tamotsu).

Notes[]

• In some sources, he is alternatively spelled Schwartz or Suworutsu.^[3]
• The existence of Another Decade was foreshadowed by the erection of his statue shown outside Another Zi-O II's residence.
• Another Decade's demonic design reflects to Tsukasa being called a "Devil" by the Decade cast several times.
• The legs of Another Decade resembles that of Decade Complete Form.
• Another Decade's belt is the twisted version of Decadriver that is shaped as an eye. It vaguely resembles the cyclops' eye of Great Leader of Shocker.
• 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.
• As with most Another Riders, Swartz as Another Decade serves as an antithesis to Tsukasa Kadoya. Although each bestowed the ability to warp time and space, Tsukasa sought to protect his loved ones as his very existence inadvertently bridged the A.R. Worlds. In contrast, Swartz intentionally sought to unifying the worlds to rule over, even sacrificing his sister and comrade to do so. This is reflected in their role towards Sougo; Tsukasa guides him to a better future, and Swartz sought to ensure Sougo cannot escape his fate as a demon king.
• In episode 46, Swartz gave Sougo Tokiwa three impossible ultimatums when it came to facing him. If Sougo defeats Swartz, Tsukuyomi will disappear with him. If Swartz defeats Sougo instead, he will absorb his powers from Sougo. A third option is for Sougo to become Ohma Zi-O. Ironically, these three outcomes came to fruition in the final episode which led to his downfall.
  • Sougo becomes Ohma Zi-O after Geiz sacrifices himself.
  • Sougo defeats Swartz as Ohma Zi-O, and Tsukuyomi dies in the battle.
  • While Swartz did not defeat Sougo, he did attempt to absorb his Ohma Zi-O powers.
• Swartz was originally planned to be Sougo's son.^[4]
