It'd honestly be really sad if Zi-O didn't do anything on TV to pay homage to those shows beyond the Ride Armors getting brief appearances. Kuuga is a significant show for obvious reasons and W is a hugely popular series that was also the beginning of an era in its own way. Ignoring them just wouldn't be right, especially when neither of them plays a huge part in this movie.

Plus, even Gokaiger still did tributes for other teams even though they already got their Greater Powers (DaiRanger, Boukenger and Go-Onger) and had a MammothRanger representative in their penultimate episode.

Yes, getting Odagiri is still impossible at this point (because even Hiro Mizushima who expressed interest to return as Kabuto but ultimately didn't). But they can always have Ichijo, and Shotaro reprised his role multiple times in the past, he wasn't in this movie because Renn Kiriyama was in Egypt during filming, so he is likely available now.

Philip, drive, and deno are on the list of unapproachable actors. Deno was a short surprise. He's talented, but I expected his short stature to cripple him to play typecast roles or smaller roles, but he best out a lot of people from playing kenshin to other roles. Meanwhile, zeronos actor came out of retirement and grateful to be back to toku playing a big roles in hibiki and deno main arc.

Didn't Philip's actor say he wanted to come back from the movie but couldn't because of time
