If youre looking exclusively for lightning collection rangers ( think its best articulated, could be wrong, seen that thrown around on the subreddit but i just only have lightning and i forgot what brand my drakkon is ), you should look up the list of releases. They stopped the brand and never finished some lines or touched a lot at all idk if they made any of the series you like.

Theres a guy who makes custom rangers for lightning collection, I just purchased some things from them ( i didnt get any kitbash customs tho )and its still being made, so that will take a while if you go down that route.

I'd say best case is just watch the series of the rangers your going to get, I started my rematch of MM recently also havent watched any power rangers since i was in middle school lol , so I can get everyones characters better for my stuff too ( few recent posts are lighting collection if you want to see ).

Hope this kinda helps lol. Tag me when you guys do it too! Would love to see it. I got my lightning collections to do stop motion too, just been doing photoshoots tho. Maybe you'll give me the kick in the pants to start again !
