You fools could never defeat me. And do you know why? Because I was born to be king!
~ Oma Zi-O boasting about himself.

Oma Zi-O, born Sougo Tokiwa also known as the Demon King and formerly known as Kamen Rider Zi-O is the titular overarching antagonist of Kamen Rider Zi-O. He is the future self of Sougo Tokiwa, who achieved a nigh-omnipotent status in the future and rules the Earth in the year 2068 as its king.

He is the reason that most of characters travel back in time, either in order to stop him by eliminating Zi-O or preventing Sougo from becoming Zi-O, like Geiz, Tsukuyomi and White Woz, or coronating a person other than Sougo to be Oma Zi-O, like the Time Jackers.

In his rise to power, Oma Zi-O devastated the world into ruins and wiped out half the population. As others travel back in time to stop his rise to power, Oma Zi-O sends his prophet Woz to the year 2018 to ensure his past self completes his journey into the Demon King.

He was voiced by Rikiya Koyama, who also played Kagetane Hiruko, Giovanni in Pokémon Origins, Kiritsugu Emiya, Kamen Rider Bujin Gaim in Kamen Rider × Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle and Paradox Roidmude in Kamen Rider Drive: Surprise Future. As old Sougo Tokiwa, he was portrayed by Seiji Takaiwa, the suit actor who is known for playing the primary roles in suits except Kuuga and Hibiki.

History[]

2009[]

When Sougo was young he was abducted along with several other children on a bus trip and had Swartz whisper in his ear that he would one day become king. Secretly, Sougo's rise to power was manipulated by Kamen Rider Barlckxs and the Quartzer.

2018 - 2068[]

On a day known as the "Day of Oma", Oma Zi-O conquered the world with seven machines called Dai Mazines, using his vast powers and time manipulation to wipe out half of humanity and subjugate the rest. A resistance soon arose to oppose him, but Oma Zi-O easily suppressed them. In the first episode, he is seen using his powers to fight them off before boasting of the fact that he was "born to be king". Unable to defeat Oma Zi-O in the future, two members of the Resistance, Tsukuyomi and Geiz, traveled to the past to change the future by changing his past self's fate of becoming Oma Zi-O.

After Sougo Tokiwa was flung into the future by Kamen Rider Decade, Oma Zi-O had Dragreder bring his past self and Tsukuyomi to him. The Demon King reveals himself as Sougo's future self, shocking the past Sougo. Deducing that his past self was in denial about becoming the Demon King, the future Sougo tells his past self that it's their destiny to become king and "save" the world. Angered, the past Sougo transforms into Kamen Rider Zi-O and attempts to attack his future self, but the future Sougo transforms into his Kamen Rider form as well and beats him down. As Oma Zi-O continues to pummel Zi-O he offers his past self a choice, telling him that if he doesn't want to become the Demon King then all he needs to do is destroy his Ziku-Driver.

Soon after Oma Zi-O launched an attack that forced Sougo out of his transformation. Oma Zi-O then opens a window in time to display his servant Kasshin beating down Kamen Rider Geiz Faiz Armor. Oma Zi-O tells his past self to return to 2018 and creates a time portal to allow the past Sougo and Tsukuyomi to travel through back to their time.

Future Sougo then reverts his transformation and takes a seat on his throne. In 2018, Sougo allowed Geiz to destroy his Ziku-Driver causing Oma Zi-O to be erased from the timeline. However, Sougo would later become Kamen Rider Zi-O again, and as a result his future was restored as well. As he's returned to existence, the future Sougo let out a laugh, revealing he knew what decision his past self would make.

Once Sougo acquired the Trinity and Blade Ridewatch, Oma Zi-O had Daiki Kaito deliver a message from himself to his past self where he congratulated past Sougo for obtaining the Blade Ridewatch, before manifesting the six remaining Ridewatches and telling his past self that once he collects the powers of the six remaining Kamen Riders he will become king.

Oma Zi-O v GrandZi-O

Oma Zi-O duels his past self.

After present Sougo achieved the power of GrandZi-O from obtaining the power of the past 20 Riders, he traveled to 2068 to face Oma Zi-O again. However, Zi-O found he could not match up to his future self as he still had yet to obtain one Rider power, the power of Kamen Rider Drive, which had instead been stolen from Oma Zi-O by Geiz. When Zi-O summoned Drive Oma Zi-O turned him against Sougo and used him to force Sougo out of his transformation. Though untransformed, Sougo got up and attempted to face off against his future self again. Oma Zi-O then unleashed a flurry of explosions against his past self, before Woz swept Sougo up in his scarf and sent him back to 2019. As Woz bowed before his Demon King, Oma Zi-O realized that someone had changed the flow of time, resulting in a future where Hiryu Kakogawa became Oma Zi-O. This timeline was averted when Sougo Tokiwa as Grand Zi-O defeated Hiryu as Another Zi-O II, restoring history to normal.

Kamen Rider Zi-O: Over Quartzer[]

As Sougo is confronting Kamen Rider Barlckxs, Oma Zi-O appears to his past self to give him a speech inspiring him to not give up before delivering the Oma Zi-O Ridewatch to him.

Oma Zi-O vs. Zi-O Trinity[]

As Swartz commenced his final plan to merge the worlds together Sougo traveled to the future just before Geiz and Tsukuyomi went back in time to confront his future self again. Sougo found Oma Zi-O repelling an attack by the Resistance and told the Resistance fighters to retreat while Sougo faced his future self. Summoning Geiz and Woz from his time, Sougo became Zi-O Trinity to fight Oma Zi-O. The fight proved fairly even, until Sougo told Oma Zi-O that he had an advantage over the future tyrant in that he had friends. Oma Zi-O then revealed that in order for Sougo to save his friends and their world, he would have to sacrifice himself. Detransforming, Sougo sent Geiz and Woz back to 2019 while he talked with his future self, commenting that it was pointless for them to fight since Oma Zi-O didn't want to kill his past self and that Sougo didn't want to fight him either.

Sougo then asked Oma Zi-O what the power of Oma Zi-O was, to which his future self stated it was the power to destroy space and time. He then further revealed that the reason Swartz engineered Oma Zi-O's rise was because he lacked the power. Sougo vowed to never become Oma Zi-O, but his future self told him to not be so sure before sending him back to his own time.

Final Battle and Conversation with his younger self[]

After past Sougo became Oma Zi-O and defeated Another Decade, his future self appeared before him to ask him about the choice he made not to become king, telling him that he earned the right to rule as king as he was the one who saved the world. However, past Sougo tells his future self that it wasn't he who saved the world but Geiz, Tsukuyomi and the power of the past Kamen Riders. Past Sougo goes on to further say that he doesn't want to be king in a world where he is alone, to which future Sougo remarks that he chose a noble path over military rule. Past Sougo then asks if the powers of Oma Zi-O can only destroy, and his future self answers that they do because destruction must come before creation. Conceding to his future self that he is right, Sougo then states he plans to use the powers of Oma Zi-O to rewrite history. Oma Zi-O warns his past self that if he did that, he wouldn't become king again in the future, but Sougo replies that he still believes he could. Letting out a hearty laugh, future Sougo tells his past self that it was a pleasure to see him before fading away as Sougo rewrites history.

Rider Time: Kamen Rider Decade VS Zi-O[]

Oma Zi-O managed to survive Sougo rewriting history, but was stuck between dimensions. He managed to escape at the cost of his power, and thus set up a game on a mysterious island to select a suitable host. He selected Narutaki to oversee the "King Game", which involved an abducted group of people partaking in various challenges, with a loser being eliminated each round via execution by Another Ryuki. However, after several rounds of the game, Narutaki began to grow bored of it as none of the people they had selected proved suitable, and thus he secretly lured Kamen Rider Decade to the island so he could stop it.

After Tsukasa discovered what was going on, Oma Zi-O intervened and teleported the surviving contestants to a barren field for them to fight in. Tsukasa transformed into Decade and fought Oma Zi-O, receiving help from Kamen Riders Kamen Rider Diend, Kuuga and Kiva-la, but the four were unable to match the tremendous might of Oma Zi-O. Oma Zi-O then used his powers to reset the timeline.

Rider Time: Kamen Rider Zi-O VS Decade[]

In the process of resetting the timeline, Oma Zi-O merged several parallel worlds together, resulting in six alternate Sougo Tokiwas and their high schools winding up in a barren wasteland terrorized by Elementary Inves. As a result, Oma Zi-O's body regressed back to that of a child.

While wandering the world, the child Oma Zi-O ran into Tsukuyomi, who was not aware of his true identity. After defending the child from a group of Elementary Inves, Tsukuyomi took the "True Sougo" under her protection and brought him with her as she traveled to Sougo's high school.

Upon their arrival, Oma Zi-O revealed his true nature and pulled out his Oma Driver, using it to transform into Oma Zi-O. Sougo and Tsukasa transformed into Kamen Riders Zi-O and Decade 21 Complete Form, but Oma Zi-O overwhelmed both of them, defeating and fatally wounding Tsukasa. Before passing on, Tsukasa handed Sougo the Saber Ridewatch, which he used in conjunction with the Decade Ridewatch to assume DecadeArmor Saber Form. Oma Zi-O then battled Zi-O one-on-one, but was beaten back by the Saber Ridewatch's power. He attempted to perform his finisher, but at the last second was distracted by Tsukuyomi calling out to him, allowing Zi-O to finish him off.

Kamen Rider Zi-O (novel)[]

Through the machinations of a third Woz from an alternate timeline, Mirror Sougo Tokiwa was awakened from within Sougo and became Oma Zi-O, ruling by the year 2068 as his original self had once done.

Saber + Zenkaiger: Superhero Senki[]

Oma Zi-O appears after Rintaro Shindo, Kaito Goshikida and the Taros were sucked into the story of Journey to the West, taking the place of Buddha in the original story. He appeared before Rintaro and Kaito to tell them to assist the Taros (who had all assumed the roles of Sanzang and his companions) in their journey.

Personality[]

Oma Zi-O is shown to be incredibly egotistical, something that is only backed up by his tremendous power. He believes himself to have been born into kinghood and delusionally proclaims himself to be a Demon King who saved the world, despite the fact that he reduced it to ruins and caused the deaths of over half the human population. Despite this, Oma Zi-O is very friendly when speaking to his past self and only laughs when Sougo vows to never become him. When Sougo smashes his Ziku-Driver and undoes his existence in the future, Oma Zi-O only takes it in stride, possibly because he knows the events that will come to pass.

Despite his actions, he believed that what he has done has somehow saved the world, and has become the "greatest and kindest Demon King" as his younger self would wish to become. However, he would not become so out of kindness like Sougo, but out of seeking perfection and obtaining more power.

Sougo Tokiwa[]

Oma Zi-O[]

Trivia[]

  • His name can alternatively be spelled as "Ohma Zi-O" with the first word being an anagram for "Maoh" which in Japanese means "Demon King".
  • Befitting the series' motif as a summarization for the entire Heisei Kamen Rider continuity for the past 19 years, Oma Zi-O shows resemblence and similarities to other previous Heisei Kamen Rider villains, on characteristics and physical appearance, including:
    • Oma Zi-O shares similar name to Ogma / Kamen Rider Sorcerer, and they both have the color gold as their color theme.
    • Oma Zi-O is a villainous rider connected to time and/or time-travel, just like Kamen Rider Bujin Gaim and Kamen Rider Dark Drive. All three are also evil counterparts from another era to the heroic Riders, although Bujin Gaim is from the past, while both Dark Drive and Oma Zi-O are from future. In addition, they all share the same voice actor.
    • His red eyes and golden Rider armor bears chromatic resemblence on Tenjuro Banno as Gold Drive and Masamune Dan as Gamedeus Cronus.
    • Like Bat Fangire (as the original Kamen Rider Dark Kiva) from Kamen Rider Kiva, Oma Zi-O is the evil counterpart to a heroic character with the same Rider Armor (P.S. Taiga Nobori became Dark Kiva in the finale of Kiva). However, Oma Zi-O is the future evil counterpart of Sougo himself, while King is both the father and past predecessor to Taiga. They also both have "King" in their title.
  • Curiously, Oma Zi-O's "eyes" resemble to shape of an eagle, possibly hinting at a connection to Shocker. The logo of Zi-O, which is depicted on Oma Zi-O's forehead, also shows an "X"-like symbol, which could perhaps hint at a connection to Foundation X as well.
  • Both Oma Zi-O and (Kamen Rider) Zein are the epitome of the "Beware the Superman" trope in the Kamen Rider series because of their use of Kamen Riders' powers to subjugate humanity. The only main difference is that Oma Zi-O has the powers of every good and evil Kamen Riders, including Zein's. Zein is only limited to, as of Kamen Rider Gotchard, the Double Riders to Gotchard.
    • As Zein serves as an evil counterpart to all of the protagonist Riders, Zein represents what the present Sougo could become had he successfully gathered his Rider predecessors' powers without the interferences of Geiz, Tsukuyomi, and even the Time Jackers, became Oma Zi-O and rule the world unopposed.
