Music sounds good. Maybe the distinguishing part of the name could be letters (specifically A-G), with flat and sharp forms...

Yeah, they could easily just be a bunch of animals likened to that period/location. Horses, buffalo, uh... prairie dogs? There's probably more. :lol

The problem with that is it's so situational it's difficult to use well. A sea based Sentai would probably go the way of Kyoryu's music/dance theme and just be sporadically brought up.

Hell, the military/technology themed Ohranger used a sphinx as a main component. After that, I'm pretty damn skippy anything is fair game now.

It may have been done already, but I'd actually like to see another time travel Sentai.

Not really a theme, per se, but I want to see a Sentai with honest to goodness superpowers.

I'm down with that. Perhaps this time there could be more exploration involved?

Everytime "time travel" comes up as a motif across various franshises it seems like the protagonists end up going back in time only to stay there for the whole series... as though it might as well not even be a motif.

About time for a TPotW (Time Period of the Week)

I dunno. I don't think Japan has very many interesting time periods past what their Edo set provides.
Unless the characters travel the world, too, which would be both interesting and confusing :lol

I want to see each ranger come from a different time period, it's stupid i know.

I may be,but half of the reason sentai is what it is is because of the mecha.

Animals like GaoRanger and Gingaman.
