I was thinking either him and Narutaki become an unlikely duo trying to right the wrong of whatever happens in the movie or have him hop to our reality and Tsukasa and rider alumni actors go on an adventure and eventually become the riders their characters transformed into. If they do go with the latter I can image stuff like Murakami freaking out when Tsukasa tries to force the actual Kaixa Driver on him or one of the actors forgetting the henshin pose because they haven't done it in a while. :lolol
It doesn't even have to be the titular riders too, as long as they get whoever is up for it.

Wouldn't anyone like to see a Blade anniversary where Amane transforms using Chalice's powers in Leangle's system?

And what of a Kabuto anniversary? Kagami becomes Kabuto permanent? And who'd be the new Gatack and Kick Hopper returns. I question who'd replace Kageyama as Punch Hopper whether it's a male or female.

Plus Kabuto could use some female riders, depending on the insects.

I'm surprised Misaki didn't use TheBee in Kabuto. This suit changed owners more often than the belts in Faiz and at least once could give her a try.

The Bee Zecter chooses people with absolute loyalty to ZECT, so it would've abandoned Misaki eventually.

Eventually it abandoned everyone, but it would be worth a try.

Let's see how a Kabuto anniversary movie can work out.

Kagami seems to become Kabuto full-time now. Who'd take his place as Gatack?

And will Yaguruma return finding a new partner as Punch Hopper? Perhaps a girl this time.

With Kagami to gain Hyper Kabuto with the TheBee, Drake & Sasword Zecters for Perfect Zecter, I'd imagine a new Gatack will have three new riders & their Zecters on his side.

And who knows how the Worms/Native Worms are coming back. Unless it's a new kind of enemy since them.

That's incorrect. TheBee Zecter chooses people with strong sense of self. It's why it abandoned Yaguruma when he eventually lost to Tendou, as he basically discarded his personal philosophy to beat Tendou, causing TheBee to lose faith in him.
However, once he became Kick Hopper and found a new path in life, his sense of self returned, despite his nihilistic world view. TheBee actually attempted to bond with him again, but he rejected it in favor of the Hopper Zecter.

Misaki before meeting Tendou would never be able to become TheBee, but post series, I think she could.

I think she was more influenced by Tsurugi than by Tendou, with whom she had little contact in the show.

Yeah, I was thinking of Renge, my b :lol

Wonder if we'll ever see a new Kiva anniversary movie?

What if it goes Batman Beyond with a new Kiva? And possibly IXA, Saga and Kiva-la joining in?

We could sure use new Arms Monsters & Riders.
