The Substitute Freedom Fighters is a group that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. They were created after an incident involving the total capture of the core Knothole Freedom Fighters after falling into one of Dr. Ivo Robotnik's traps. Also managed to rescue them and it was decided they needed a backup group and Larry Lynx was chosen to become the leader.
Training and Formation
Prior to the group's official formation, the majority of its members - including Penelope, Dylan, Hamlin and Arlo - were trainees under the leadership of Sally Acorn. The trainees managed to uncover Robotnik's Auto Automaton's and destroy the majority of them. (PSM: #1, #2, #3)
Following this, the trainees assisted in stopping Sonic from defeating the Knothole Freedom Fighters after he was ridden with amnesia and convinced by Dr. Robotnik that the Freedom Fighters were the enemy. Weeks later, after the Knothole Freedom Fighters were captured and taken back to Robotropolis as prisoners by Combots, the Substitute Freedom Fighters helped Sonic rescue them before they were roboticized.

Not long after this, Substitute Freedom Fighters were officially formed as a support group with two new members - Larry Lynx and Cyril - after they successfully freed the Knothole Freedom Fighters from a bizarre prison in a video-game universe. (SLV)
The Substitute Freedom Fighter group was effectively disbanded when three of its members - Penelope, Dylan and Hamlin - were elected as members of the Council of Acorn, which was created in 3237 following a revolution led by Amadeus Prower. (StH: #178, #179, #180)
