What would be the best 10 rider themes KR to do next for the upcoming era?

I hope in the next era we have better KRs.

Let's not be too negative here, there's always room for improvement but Heisei's Phase II had a good run all things considered.

One train wreck, one rather bad show, but the rest ranges between really good and excellent IMO.

And i hope they have a new formula too because the current one is too overused.

So am I the only 1 fully expecting the legend riders in Zi-O o to come back for another episode, but with their memories and powers restored?

Probably not all of them, but I'm sure that we'll see some of them with their full memories and powers restored near the end of the show and/or in the summer movie.

When can we get Ghost, Ex-Aid & Build SIC?

I can't answer that for sure but doesn't Ghost already have one?

It doesn't. However, the SIC-line is about to be rebooted in a sense. The initials will stay the same but the name will change from "Super Imaginative Chogokin" to "Superior Imaginative Colosseum".

They've announced that the initial Riders they cover in this line will be Kuuga, Ryuki, Fourze and Ghost.

We did see a concept art of Ghost at the Tamashii Nations event in October:

So SIC Ghost will be a thing soon-ish, Ex-Aid and Build might be coming in the future.

SIC Build would be pretty neat I bet.
