There's an R-Rated Animated POWER RANGERS Series Currently in Development
Fresh off the announcement that he would be heading up a Castlevania series for Netflix, Adi Shanker also dropped the knowledge that he is currently developing an R-rated animated series for the Power Rangers. This new series appears to be in the same vein as the fan film Shankar released a couple years ago, which you can check out right now.
Shankar promises his take on the universe will be "much darker" than the original series if you couldn't gather as much from the video. Shanker adds that scripts are being written and the series is being shopped to various networks. No word on if Power Rangers license holder Saban is on board with this, and considering they're launching their own new brand of Power Rangers, I would say no.
Still, you could do a little work with the script and turn it into an entirely new action series heavily inspired by the Power Rangers universe and still have a decent product. If you remove all the licensing from the above fan film, it's still pretty decent for what it is. I'm not putting much stock in this idea surviving long, but we will keep you updated if anything comes of it.
