The resistance itself is comprised of disgruntled citizens, most of whom are Americans, and ex-military personnel. It was created by Agito Makishima, whom calls himself Zeus. They dedicated their efforts to destroying Zoanoid factories world wide. Despite mostly being humans they are a threat to average Zoanoids.
