Power Rangers isn't actually a 100% original show. It's based of Super Sentai, which is created in Japan. All the action scenes involving monster or the rangers in outfits are usually from the Super Sentai show, hence why sometimes the girl rangers have noticeable packages and non-existent breasts.
There was a game on PS2 (not sure what other systems) that had rangers from all the different seasons up to that point. It was actually a really fun game and you were able to unlock different rangers along the way. They should do another game like that featuring all the rangers. It could be massive and it'd definitely attract a wide audience.
