I'm surprised they're doing a second Drive arc, when they still haven't brought back anyone from Kuuga. Unless I've missed something, it's the only series they didn't get a single actor from in the TV show. Granted, there's still three episodes left, a last minute surprise is still possible

CHASE!

So that makes a returning Rider from every series apart from Kuuga in series, right? That's pretty good going.

Chase is one of my favorite Riders. So excited for this!

Also Kiva and Fourze. Here's hoping for Nadeshiko...

A separate guest in 48 is still possible too. There's a very large number of suit actors there.

Jiro was 86' Ixa for a while, although Zi-O didn't reference it.

I suppose so... not entirely sure I count him as Ixa, though.

Though if you really wanted to, you could say that technically Jiro and Minato are Kiva and Fourze's returning riders.

Fourze showed Gentaro from behind with a voice dub, that counts enough, right? :P

I more prefer if Gentaro in Fourze suit are interacting with Sougo just like Kouta in Gaim suit are interacting with other Riders in Dr. Pacman vs Heisei Generations movie....

Also, since Godai's actor are more likely will not return in Zi-O, I think it will be really interesting if Riku is revived and appeared in Zi-O series or movie and Riku's actor are suit actor for Kuuga....

Riku's actor also portrayed as Kamen Rider Abyss in Rider Time Ryuki....

It's too bad that Onodera is hated by the fandom. I think Toei really intended for him to be Kuuga's proper successor. If he was written better maybe fans would've liked him and he'd appear in Zi-O

I don’t think so? AFAIK, Onodere is only hated by the Western fan base, which Toei/Bandai don’t care about. IIRC, he isn’t hated in Japan, just normal.
