Substitute Freedom Fighters

The Substitute Freedom Fighters 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. They 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)

Missions
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)

Disbanded
The Substitute Freedom Fighter group was effectively disbanded when three of its members - Penelope, Dylan and Hamlin - were elected as members of the Acorn Council, which was created in 3237 following a revolution led by Amadeus Prower. (StH: #178, #179, #180)
