Again, kuuga is a nope. Really miss the day to day realistic darker and cynical plot with civilians roaming around like real people. It's too commercialize for him to return. He's more of an actor that see toku as stepping stone, but he appreciate the fame he receives and fans that enjoy the series. It's kind of like the original pr that joke about their bad set experiences and low pay like shinkenred and yuki from fourze.
Agito cameo decade like jdf in legend war and he did record lines for the games a few years ago, so maybe voice the suit. The same with gills.
Ryuki and knight also lend their voice before, so maybe voice over.
555 and Kaixa were confirm, but their stories ended in kr4 already and taisen, so more retcon to the tv series. Kaixa wasn't really a main character compares to kiba's group and mari. Maybe the snake will Cameo again.
The whole gang for blade promoted the bluray, but one of the four retire from acting. Blade and garren are free and reprised their roles before.
For hibiki, maybe the wolfman can reprise his dead role.
Imagins are easy. Idk about owner and rina akiyama.
Kabuto, despite being an anniversary series with many hopes, it's easily forgotten. Still good to me since it's my first subbed series despite I've seen some Raws of other toku in other languages before besides pr. Gattack was nostalgic and enthusiastic about the toys, so maybe. Yaguruma was in goonger 10th anniversary, so it's easy if they want at least one rider or ally from each heisei series.
Kiva-grease-new Kiva.
Decade-I forgot about au kuuga was the hidden 2nd rider really. Decade was in wizard and he's a power up for zio, so maybe since he's with garo now.
Black/black Rx and ichigo and v3 still reprises their veteran role like Gavan a lot, but idk if Showa are being explored. It's just time jumping around 2000-2018.
W,ooo,fourze,wizard,gaim,drive,ghost,exaid,and build are likely, but not if they want to feature one every two episodes since there's schedule conflict and monetary reason. Might save up the budget for the movie war.
