[Xtreme RX]

Here's what I'm thinking/hoping:

-Hibiki: While it'd be nice to see Ibuki, Todoroko, Zanki or Amaki again (and we know they'd be willing to return), I would totally be down with just Asumu and Kiriya. See what has changed about them in 14 years. Is Asumu a licensed doctor at this point? Has Kiriya become a full-fledged Oni? I think this would be exciting to explore. If they bring back more cast members, that'd be bonus. It's doubtful Hosokawa would return based on what's going on with him and TV Asahi, but it'd be a nice surprise and I would love to see Hibiki acting as sort of a mentor to Sougo and Geiz. A reunion between Hibiki and Asumu would be really emotional too.

-Kabuto: Mizushima is willing to return, capitalize on this Toei!! This would literally smash the ratings for Zi-O if he actually does make an appearance. Otherwise, Kabuto is one of those series that never had much in terms of returning cast members, even in cross-overs (aside from Kick-Hopper), so I'd take anyone. The most obvious choice would be Gattack, but Drake, Sasword, hell, even Kickhopper would be a-okay with me.

-Den-O: The Imagin and Ryotaro were covered (spectacularly, apparently) in Heisei Generations Forever, so I'm gonna say Yuuto and Deneb would be great for the in-show tribute. Heck, make this one a double tribute, literally - The film was a Den-O tribute in which Sougo got the Double RideWatch, so make this the opposite. I know Double and Kuuga are taken care of thanks to said film, but I still hope we get to see at least one returning actor from each respective show before Zi-O's time is up.

-Kiva: I'd love to see Koji Seto back as Kiva, but that's really up in the air. I'm happy with IXA/Nago or the Fangire Hunter girls. They'll get Kouhei back as Otoya for sure. This tribute can take advantage of the time travel shenanigans by exploring both 2008 and 1986. If they want to involve future time travel, Masao/Future Kiva and the Neo-Fangire threat could be a plot point worth elaborating on and would definitely make for good fan service.

-Drive: Takeuchi Ryoma would be another ratings-booster, and who knows? Toei might actually have a better chance here since they are on good terms with him. If not, Gou and Kiriko would be good choices. And if they are still doing story continuations at this point, it'd be nice to see Chase come back for good too. Also, based on Shirakura's tweet about the Drive Tribute, it could involve Surprise Future's plot. So Tomari Eiji or evil Krim Steinbelt are not out of the question either.

Either way, stoked to see what happens next!
