Sonic The Hedgehog - Season 1

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. The 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 conquers Robotnik's latest evil — a vehicle designated to locate and destroy living tissue matter — during a solo mission to the Badlands. Upon Sonic's return, the Freedom Fighters honor him with a victory party. Envious of the attention Sonic's getting, especially from Sally, Antoine sets out on his own solo mission to prove his worth by capturing Robotnik. Upon arriving in the Badlands, Antoine lures Robotnik into an underground trap, using a much-desired Power Ring as bait. Unfortunately, Robotnik makes a quick escape, taking the lone Freedom Fighter prisoner. Sonic learns of Antoine's disappearance and speeds off to his rescue. However, Sonic discovers that his speed has been neutralized by Robotnik's newly devised radar-detecting system, powered by the confiscated Power Ring. Sonic overcomes the odds and, without maximum use of his speed, frees Antoine. Antoine returns the Power Ring to Sonic, restoring Sonic's speed and allowing for a quick getaway. Although the gang is upset with Antoine for taking a foolish chance, Sonic emphasizes Antoine's bravery and grace under pressure and initiates a celebration in Antoine's honor.

When Robotnik launches a spy-orb that will uncover the Freedom Fighter's Knothole location, Sonic and Robot launch themselves up to the orbiting spy-sphere aboard a home-made rocket powered by Robotnik's discarded booster engine that fell in the Great Forest. Once on the heavily guarded sphere, Sonic and Robot must find the spy sensors before they locate Knothole.

When Sally uncovers Robotnik's plan to seed the cloud with toxic rain, they attempt a daring mission to sabotage the dirigible-like craft being transported by land vehicles. Mission fails when Sally, Bunnie and Antoine are captured and taken to an oil refinery island in the Great River. It's up to Sonic to not only sabotage Robotnik's cloud-seeding, but rescue his friends as the island literally sinks beneath their feet.

When Sonic and The Freedom Fighters take out Robotnik's main computer, they're trapped by Swat-Bots in an underground tunnel, only to be rescued by a handsome teenager named Griff. Griff takes them deep beneath the Big City, where Sonic has to fight off some Rat-Bots. They finally arrive in lower Mobius, where a group of Mobians have taken refuge from Robotnik and built a community, which is dependant on an energy cube for all its power. Unfortunately, the energy cube is losing its power, which Griff keeps a secret. Later at Knothole, where Griff learns of Sonic's power ring, he steals the power stone from Knothole's grotto and returns it to lower Mobius to replace their fading energy cube. Sonic tracks Griff back underground, saves his from a pack of Rat-Bots and ends up giving Griff a piece of the power stone.

Robotnik severely upsets the ecosystem above and below the surface, when he sends explosive, Robotnik snake probes drilling deep under ground in search of oil lakes. After being swept into an underground world by a whirlpool, Sonic, Sally, Antoine and Robot discover a strange creature who claims he is the last of a people who have been destroyed by surface creatures and blames the Freedom Fighters for his plight. Robot gets a chance to become a hero for a change, when he saves Sonic and the others from a toxic pot of techno-junk, but it's up to the Hedgehog to turn the tables on Robotnik and destroy his drilling platform and team of lethal snake probes.

Tails brings a new friend home to Knothole — a baby Terra-Pod who has strayed from the herd that is currently migrating. Sonic, Sally, and some of the other Freedom Fighters return the Baby-T to its mom and the rest of the herd as they pass by Knothole on their migration run. However, Sally realizes that the herd is going in the wrong direction. Something is wrong. Robotnik is trying to capture the pods as they are the final animal species on Mobius to be roboti-sized. Things get dicey when the herd decides to head into the mysterious unchartered Great Jungle, where few who have entered ever return. Sonic foils Robotnik's attempts to capture Baby-T's mother, rescues all the Freedom Fighters and terra-pods from an imprisoning force field and survives the dangerous plant life of the Great Jungle.

Sonic reluctantly takes Tails with him to the Big City to find some cotter pins for the Freedom Fighters catapults. While in the City, Sonic is nearly eaten alive by his old dog Muttski, now a roboti-sized guard dog in the Junk Heaps. Later, while escaping some Swat-Bots, Sonic and Tails overhear Robotnik explaining his plan to defoliate the Great Forest with a chemical spray and reveal Knothole. After a harrowing chase, Sonic and Tails return to Knothole and reveal Robotnik's plan to the other Freedom Fighters. They come up with a daring plan to stop Robotnik's defoliating scheme that involves Sonic's speed and the catapults.
