S1, E1: Sonic and The Freedom Fighters journey to Robotnik's underground air base in a mission to reprogram the launch data on Robotnik's fleet of Stealth-Bot aircraft. While attempting to reprogram the Stealth-Bot computer system, Sally receives a computerized message she believes is from her father, indicating that he may be located somewhere within the Dark Swamp. Despite Sonic's warnings, Sally and Antoine set off on a dangerous mission to find Sally's father, during which they are detected by Robotnik's radar system and lured into an underground trap. Meanwhile, during a high-speed chase with Robotnik's Swat-Bots, Cat is captured and held as Robotnik's prisoner. Sonic must turn on the "juice," dodging missiles, outwitting slimy creatures, and eluding Robotnik-set booby-traps in order to rescue his friends and eliminate the threat of the Stealth-Bot.
