Sentai Season Without a PR Adaptation

This category is for post-Jetman Sentai season that doesn't have a Power Rangers adaptation. Much like Tokumei Sentai Go-Busters (Power Rangers Beast Morphers), these seasons may get adapted in time, but were skipped over for the moment.

To qualify, the season must have preceded the Sentai season currently being adapted into Power Rangers; as such, Mashin Sentai Kiramager and Kikai Sentai Zenkaiger are ruled out, as these seasons made their debut after Kishiryu Sentai Ryusoulger, which is being adapted into Power Rangers Dino Fury and is the most recent season to be adapted.
