The Prehistoric Freedom Fighters are the counterparts/ancestors of the Knothole Freedom Fighters on Prehistoric Mobius. Living in a world inhabited by fierce dinosaurs and the antagonistic caveman Ivo Robughnik, they relied on burrowing underground to avoid harm. However, Sonic the Hedgehog convinced them of the error of this course of action, and helped them develop a new lifestyle by planting hedges as hiding places. (StH: #12)
- The Prehistoric Freedom Fighters may be loosely inspired by the Flintstones, particularly in terms of their attire.
