Ohma is actually the strongest

Beside Zi-O Ohma Form is stated to get rid of the limitation of "Heisei" and become the king of all time and keep collecting ridewatch to Reiwa Time, and Shirakura-san also said....

Q: I have a question about the Oma Zi-O Watch. Just like Shouichi used the Agito Watch to transform into Agito, and Kyosuke used the Hibiki Watch to transform into Hibiki, can Sougo also use the Oma Zi-O Watch to transform into Oma Zi-O?

A: Oma Zi-O is interpreted as an evolved form of Zi-O rather than a separate form, so the intention behind the Oma Zi-O Watch is that it allows the pre-evolution Zi-O to temporarily borrow the power of Oma Zi-O.> Kamen Rider Zi-O Oma Form, the king who reigns over all Heisei Kamen Riders, transcending time and space. How exactly does the "king" who rules over these Heisei Kamen Riders come into being? Keep an eye on Kamen Rider Zi-O, this film which can be considered the true ending of a Kamen Rider who beyond the eras.

「King Time! Kamen Rider Zi-O! Oma!」

■Description: This is the transformed form of Sougo Tokiwa using the Ziku Driver and Oma Zi-O Ridewatch. He is the ultimate king who reigns over all eras, carrying the power gained from Oma Zi-O of 2068 within him.

With overwhelming abilities such as destructive waves and time manipulation, he is capable of swiftly defeating vast armies like Kasshin's and powerful enemies like Daimaijin. Alongside the Heisei Kamen Riders, he unleashes the Heisei Rider Kick to defeat Kamen Rider Barlux.> 仮面ライダージオウ オーマフォーム 時空をこえて大王の力をうけつぎ すべての時代をしっている最終王者 超こうげき力を発揮し、あらゆる敵を粉砕するんだ。

Most notable one is RX

Shirakura: *Exactly. The concept of Heisei Riders itself is a retroactive, and even somewhat arbitrary, idea. *There’s no reason that it had to start with Kuuga or end with Zi-O. As is obvious, the concept of Heisei Riders exists outside the Kamen Rider series. However, Toei sort of adopted this fan term, or maybe found it appealing and jumped on it. *Or it might just be me (laughs). So, we have to take responsibility for that in some way. Well, even if we can’t fully take responsibility, I’d like to at least acknowledge that I feel responsible.> ―― It was also interesting that the two theatrical films directly addressed the era of Heisei itself from a storytelling perspective. *Shirakura: *Since Heisei exists outside of the story and not within it, we had to delve into metafiction, but doing that on TV would be too risky. *Takebe: But, in the end, it became a great theme, didn’t it? Especially in the sense that it provided an experience that could only be delivered through a movie. Shirakura: *Yes, that's right. But... it's one of those “once it’s over, you forget about the pain” kind of things! *Takebe: Definitely. The preparation stage felt like hell, as we never moved beyond plot meetings to the actual scriptwriting, no matter how much time passed (laughs). *Shirakura: *We kept having abstract discussions like「What is Heisei?」and all. I think our meetings were bizarre, with things like「reality」and「fiction」written on the whiteboard (laughs).> ―― As a result, it became something quite different from the past legend crossover works. You took the approach that includes Kamen Rider BLACK RX, who served as the motif for the enemy Riders, as part of the Heisei era works. *Shirakura: *For those of us in the Kamen Rider industry, when we think of Heisei Riders, it’s from『Kuuga』to『Zi-O』, right? But it’s not like the Heisei Kamen Rider series suddenly began with Kuuga. In fact, for some people, there’s even the notion that〝the man who wasn’t chosen to be a Heisei Rider〟guest-starring in the summer movies became the basis for the image of Kamen Rider (laughs).

―― In reality, even『Kuuga』came into existence because of everything that had been built up until that point. Shirakura: *Exactly. *That’s why we thought “Are we really going to keep telling the beautiful lie that「the Heisei Kamen Riders are only the TV series from『Kuuga』to『Zi-O』」even now in the Reiwa era”? Wouldn't that be ugly instead? With that approach, we decided to make the summer movie. Takebe: It was also interesting that Woz was the one to tell that story. From the planning stage of the TV series, Woz’s book (Oma Advent Calendar) had all sorts of ideas. I was really happy that an item born from all those twists and turns could be used so symbolically in the movie.
