Kamen Rider Reiwa: The First Generation Official Teaser Released!

Zero-One & Zi-O crossover movie coming December 21st!

I’m onboard to see how they bring the Zi-O cast into this without pre-emptively contradicting whatever Nobuhiro Mouri has planned for Next Time: Geiz.

Do we have to? I'd be perfectly fine with not having to see Zi-O again.

As if meager things like 'consistency' or 'logic' has ever stopped Zi-O from doing anything.

Will we see an Another Zero-One? I hope Woz can proclaim both Aruto & Sougo when they gain their new movie forms.

I still hope Takeshi Hongo (Kamen Rider Ichigo) and Shotaro Hidari (Kamen Rider Double) are appeared in this movie...

If Another Zero-One exist, probably Aruto temporary will be lose his powers so Sougo are trying to restore Aruto's power........

I would hope to see that. Maybe an Another Grand Zi-O if possible.

Just wonder how the team up & story will work?
Zero-One + Zi-O
Vulcan + Geiz
Valkyrie + Tsukuyomi
Izu + Woz

For now I agree. But I do like how they incorporated Decade into Zi-O so if Reiwa eventually ends and both are still around I would like to see them back again.

That could happen and I would love it, although what we really deserve is a crossover movie with Rider 1, Kuuga and Zero-One.

If they could get Joe Odagiri back only once it should be now.

Piece of cake. Toei makes a soundboard that can emulate Takatera's voice and then they tell Odagiri they want him in using the soundboard. The rest is history.

The crossover movie's creative lead generally is the current staff. So it's more likely this movie's plot will be tied to the current show rather than Zi-O. An Another Zero One could still happen in spite of that, but it'd need to be from initiative of the Zero One staff themselves. It won't be a story built around Zi-O with Zero One hanging around like Heisei Generations Forever was for Build.

There's a theory I've seen on Japanese pixiv wikia that the summer movie is actually part of a timeline after the tv show's, and so the winter movie could just follow it up, rather than the tv series.
