The Freedom Fighters are a resistance group created to liberate the Discovery Zone from the tyranny of Dr. Robotnik and his robot army. They came together after Sonic the Hedgehog completed a mission for Princess Sally, who then suggested that they form an alliance to bring down Robotnik. Though initially reluctant, Sonic agreed, and a new group of heroes was born. The fate of the Discovery Zone Freedom Fighters is unknown, as Sonic-who had been inexplicably pulled into their Zone-was returned to the Prime Zone. (StH: #52)
