Sonic the Hedgehog

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.

During a mission to one of Robotnik's factories, Sally is taken prisoner by Robotnik and Snively, who construct a roboti-sized "Sally" clone, complete with Sally's personality, and mannerisms. This double tricks Sonic into rescuing "Sally," whose tracking devise enables Robotnik to monitor the Hedgehog's every move. "Sally" goes undetected by all of the Freedom Fighters, except for Tails, whose intuition tells him this is not the Sally he knows and loves. However, Tails warnings go unheeded, as Robotnik continues to track the Fighters every move. "Sally" shows her true spy colors as she lures Sonic and his friends into a trap. Sonic realizes that Tails suspicions were right, short-circuits "Sally" with his super-sonic speed and rushes to the real Sally's aide. Sonic frees Sally just moments before she is to be "roboti-sized", placing "Sally" in the cell as a decoy. By the time Robotnik and Snively realize they've been had, the Freedom Fighters have returned to Knothole, just in time for the real Sally to give Tails his goodnight kiss.

Sonic and the Freedom Fighters journey to Robotnik's lab in hopes of deciphering his roboti-sizer system. While underground, Sonic spots his now roboti-sized Uncle Chuck aboard a Badlands bound mine-train and devises a plan for his rescue. The Fighters board a jet-powered railcar, dodging Hover-Units and Swat-Bots, before reaching Uncle Chuck and whisking him off into an abandoned tunnel. By placing a Power Ring in Chuck's hands, Sonic breaks Robotnik's robot-spell and is reunited with his uncle. Uncle Chuck anxiously warns Sonic of Robotnik's latest invention the "Energy Crystal", capable of destroying all life on Mobius. Warding of Dino-Bots and the usual Swat-bot brigade, Sonic and the Fighters are able to locate and destroy the Energy Crystals before the force of the power ring fades, turning Uncle Chuck back into his roboti-sized state.

Sally, Rotor, Bunnie and Antoine take off in a homemade airplane, bound for an ancient city hidden deep in the Great Mountains, while Sonic follows via his favorite transportation, his sneakers. Their quest is the "secret scrolls" that have great powers they hope to use in their struggle with Robotnik. To get the scrolls, the Freedom Fighters are confronted by a maze of booby traps and puzzles that test their intellect, strength and courage. Things go from bad to worse when Robotnik shows up with a Swab-Bot team and demands the scrolls.

While on a mission to the big city to replace Nicole's malfunctioning microchip, Sonic and Sally encounter the Guardian, a mysterious cloaked figure who guards a dormant wizard named Lazar and his computer of evil spells. Both Robotnik and Sonic believe the spells could be useful and set out to elude the watchful Guardian and steal Lazar's computer. While Sonic struggles to avoid the Guardian's many traps, Robotnik reaches Lazar's resting place and escapes with computer in tow. Upon reaching Lazar's lair, Sonic is confronted by the recently-awakened wizard, who, in a rage over his missing computer, casts a spell on Sonic, stunting his Super-Sonic-Speed. In order to regain his power, Sonic must reclaim the computer from Robotnik and return it to Lazar. Meanwhile, Sally and Bunnie have been captured by Robotnik, they become guinea pigs for Robotnik's newly acquired evil spells. Sonic gains access to the land and discovers that Robotnik has placed the girls under a submission spell. Sonic and The Guardian team up to rescue Sally and Bunnie and break the spell on them.

Sonic is hired into an obvious trap when a frustrated Robotnik decides to appeal to the Hedgehog's ego and announces a "race to determine the fastest on Mobius'. Sonic decides to join the race despite Sally's objections that she needs him on a mission to take out Robotnik's power generators. The Freedom Fighters decide to launch this mission on the day of the big race, figuring Robotnik will be too pre-occupied. The race turns out to be much tougher than Sonic expected when he sees his competition a sleek, four-legged robot called the Speed Bot, who is not only out to beat Sonic, but capture him as well.
