How about adapting Zyuohger, but introduce an original villain.

As for Zyuoh The World? I call him Chimera Ranger and he’s autistic.

Red and White Rangers a couple.

Well if they do skip over Astro Force (Or whatever Hasbro calls it) and the Ranger Team Vs Ranger Team then in 2023 Wild Prime ( Or New Hasbro name) might still be on the table maybe. If they don't do dinos next. So don't count the animal theme out quite yet. I'd call that possibility a wild card for now.

I just hope the naming for the next series as well as its arsenal, Megazords etc would be better.
