History
After the Freedom Fighters managed to restore Chuck's mind, he led them to the Crystal Mines, where he explained that Robotnik was attempting to use the Energy Crystals found with the mine to replace his limited oil supplies. As such, they got to work destroying and shutting down Robotnik's mining tools in order to prevent him from getting his hands on any of the crystals. Although being hindered by Swat-bots and the Dinobot, the Freedom Fighters were able to take control of the latter bot and use it to destroy the crane that would have pulled out the Energy Crystals.
