Sonic the Hedgehog

Sonic the Hedgehog (ソニック・ザ・ヘッジホッグ) is the title character and main character of the Sonic the Hedgehog series. He is an anthropomorphic hedgehog gifted with the ability to run at the speed of sound and beyond, hence his name, and possesses lightning fast reflexes to match. As his species implies, Sonic can also roll up into a concussive ball, primarily to attack enemies. Ever since stepping into the battle against injustice, Sonic has been the champion of peace and is renowned the world over for saving it countless times. During his many adventures, Sonic has traveled from the ends of the world to the far reaches of space and time, while facing countless trials that have tested him to the fullest, earning him many titles, allies and several foes.

Background

 * Adventures of Sonic the Hedgehog

Not much is known about Sonic's early life. He was born on Christmas Island with his abnormal ability to run at super speed, but his love for adventure eventually called him away from his home. Since then, he has spent his life traveling the globe, driven by his restless spirit, in search for adventure to satisfy his thirst for thrills.

At some point, Sonic met Dr. Ivo Robotnik and they became enemies under unknown circumstances. Sonic would subsequently fight Robotnik in an untold number of confrontations as the scientist attempted time and again to conquer the world, with Sonic each time foiling the doctor's plans. Despite their many battles, Sonic did not really account of his adversary.

Sonic is a world-roaming Freedom Fighter with a lifestyle similar to a tramp, who fiercely defends the citizens of Mobius from the evil schemes of Dr. Ivo Robotnik and his lackeys Scratch and Grounder in several comical adventures.

One day, Sonic came across a young orphan named Miles Prower and was persuaded to adopt him as his younger brother, as the young fox had no one to live with. Naming him new brother "Tails", they two of them became as close as a real family. While Sonic has his trademark attitude, he also tries his best to stand out as a responsible role model for the innocent Tails.
 * Sonic the Hedgehog (TV Series)

Sonic was raised by his Uncle Chuck in Mobotropolis, during the reign of the King. As a child, Sonic used to play with his friend, Princess Sally. Sir Charles was a top inventor of the kingdom and a personal friend of the King. Following the Great War, a warlord named Julian (later known as Doctor Robotnik) orchestrated a coup d'état and banished the King to the Void. Julian then renamed himself Robotnik and ordered that all citizens of Mobotropolis be roboticized and transformed into mindless slaves. Sonic and Sally, along with several other children, were spirited out of the city and hid inside a woodland camp that would eventually become Knothole Village. At the same time, Uncle Chuck fell into Robotnik's hands and was roboticized. Sonic remains frustrated by his inability to free his uncle from Robotropolis.

Sonic and his friends currently live in Knothole to hide from Robotnik. There Sonic, Sally, and the others then formed the Freedom Fighters and began a ten year long battle with Dr. Robotnik to take back their planet, with Sonic being one of the main leaders and their primary agent.
 * Sonic Underground

Sonic was born as the heir to the throne of Mobius, along with his siblings, Manic and Sonia. Shortly after their birth however, their mother Queen Aleena was dethroned by Dr. Robotnik and they became wanted fugitives, but the Oracle of Delphius prophecized that Aleena and her children would one day defeat Robotnik together, but only if she left her children in the care of others until then. Aleena sent the siblings to three different caretakers.

Sonic himself was left in the care of a regular family. During his early childhood, however, his adopted family was captured and roboticized. After Sonic's former adoptive home was destroyed, Sonic was taken in by his Uncle Chuck. Sonic would learn how to play an electric guitar that, he soon figured out, could also be a weapon. He then joined his Uncle Chuck and the Freedom Fighters in the battle against Robotnik over the next many years.
 * Sonic X (Anime)

Sonic hails from an unnamed world in a parallel dimension to Earth. His back-story is a mystery but it is known that he befriended Miles "Tails" Prower. One day while running really fast Tails spotted him and started to admire Sonic calling him cool. Tails eventually found Sonic's original Tornado which was in the color red. So tails decided to paint it blue, and made it faster. Sonic spotted him and they became good friends. After meeting Tails Sonic also meet Knuckles the Echidna, Amy Rose, Cream the Rabbit, Cheese and many small animals as well as constantly fending off Dr. Eggman's attempts at conquering the world.
 * Sonic Boom (Series)

While out foiling one of Dr. Eggman's evil plans with Tails, Knuckles and Amy, Sonic and his crew pursued Eggman and Metal Sonic to a distant island. After briefly splitting up, the group arrived at an ominous ancient tomb, where Metal Sonic and Eggman's newly acquired Destruction Troops cornered them. Against his team's wishes, Sonic opened the tomb and had his group seek refuge inside. As they got trapped inside, Sonic was scolded by his team for his solo-actions as they tried getting out, during which they accidently awoke Lyric the Last Ancient who showed familiarity with Sonic, much to Sonic's confusion, before trapping them in his shackles as he fled. Converting the shackles to Enerbeams, Team Sonic tried fruitlessly to catch Lyric, and so went to find Cliff to get some info on Lyric.

Finding Cliff, the archeologist unveiled that Lyric was a rogue Ancient who planned to power his Sentinel army with the Chaos Crystals to destroy all organic life, but was imprisoned by his race when they discovered his plan. Though Sonic was harshly judged by his team, they set out to retrieve the Crystals before Lyric. While seeking their second Crystal after getting split up, Sonic and Tails encountered MAIA, a robot who rebelled against Lyric, in the Abandoned Research Facility who assisted the team by creating a time portal leading one thousand years back in time to retrieve a map for the Crystals.

At they were about enter a portal, Shadow the Hedgehog attacked Sonic and Tails, intent to prove Sonic's weakness. After Sonic knocked Shadow into a time portal, he and Tails went back in time to Lyric's Weapon Facility where they helped a younger MAIA halt Lyric's operations while they confronted a younger Lyric. While Tails got the map, Sonic held Lyric back and trapped him for his future imprisonment by the Ancients, upon where he realized Lyric's previous knowledge about him.

Back in the present, Sonic and Tails regrouped with Knuckles and Amy to continue the hunt. Along the way, they had to content with a short alliance between Lyric and Eggman, Metal Sonic who had been reprogrammed to serve Lyric, and the power struggle between Lyric and Eggman. Regardless, the team overcame it all and got each Crystal.

When getting the last one though, Sonic was surrounded by Lyric's robots and Lyric demanded the Crystals in exchange for Sonic's life. Sonic refused, but Tails, Knuckles and Amy complied. Despite that, Sonic got shot by Lyric's robots and buried under rubble. However, he recovered and the team went after Lyric to Lyric's Lair. Proclaiming his friends were his strength, Sonic fought Lyric with his team. During the battle, Lyric used the team's Enerbeams to ensnare them, but before he could finish them, Eggman ambushed Lyric from behind, freeing the group. Sonic subsequently tied up Lyric with assistance from his friends, during which Shadow dropped by, and removed Lyric's technopathy device to incapacitate him. With the threat over, Team Sonic celebrated their victory in the Village, with Sonic having gained a new sense of appreciation for his team.

In Sonic Boom: Shattered Crystal, Sonic and his team saved Sticks when she was caught in a rockslide, who gave them the warning that an underground army would destroy them all. Later, Sonic was contacted by Amy, who was out researching the Lost Crystal of Power, over their AVA. Through it, he saw Amy being kidnapped by Lyric the Last Ancient, who sought to rip her knowledge of the locations of the Crystal Shards from her brain.

Starting a rescue mission, Sonic assemble Tails, who found a way to track Amy from her data logs, and Sticks, though the latter's attempt at an impulsive rescue forced Sonic to rein her in and convince her to work with them. On their way, the trio found Knuckles, who had been guarding Amy's path, and recruited him for their search too. The team soon after met Shadow the Hedgehog, who acted peculiar before challenging Sonic to a showdown. After Sonic beat Shadow, the heroes learned from Shadow and his busted Mind Control Device that he had been controlled by Lyric, who then contacted them over a hologram and warned them that he would soon have the power of a god and would destroy them once he was done with Amy. While Shadow left to get revenge on Lyric, Sonic and his friends resumed their search.

When entering an ancient robot plant, Team Sonic was attacked by Metal Sonic, whom Sonic defeated. They followed the robot to an island, sure it would lead them to Lyric, where they found a plane that they used to reach Lyric's air-stationed stronghold. There, they freed Amy and confronted Lyric, where Sonic proclaimed the power of solid a team. Lyric thus separated Sonic's friends from him with a trap, but Sonic defeated Lyric and freed his team. Lyric then called forth a weapon to kill Team Sonic with, but thanks to the arrival of Shadow, the weapon was stopped and Sonic was able to drop Lyric from his airship. Concluding their adventure with a teamwork discussion, Sonic headed home with his team, though disappointed that Shadow had no interest in joining them.

Sonic then became the leader of Team Sonic. Though initially kind of a loner, the many trials Sonic faced during his battles against Lyric taught him the importance of teamwork, and he has since grown into a capable and admirable team-mate and leader.

Personality

 * Adventures of Sonic the Hedgehog

Sonic is not just quick on his feet but quick witted. Coming up with plans and disguises on the spot, Sonic uses his smarts and impressive speed to trip up the devious Dr. Robotnik.

While Sonic enjoys helping people out, he can get annoyed if someone tries to help him out. He feels that this will land them both in danger, and his temper can get the better of him (like with Captain Rescue). Sonic usually apologizes later though, showing that he didn't mean to get angry.

Sonic is very overprotective of his young charge, Tails. Tails is quite young so Sonic is the role of big brother and parental figure to him. He does what he can to keep the fox safe and has some rules in place to keep Tails away from his dealings with Scratch and Grounder. He is shown to become angry with Tails when he disobeys these rules and puts himself in danger, indicating how important Tails is to him.

Despite the mischievous attitude he is given in the main show, during the Sonic Say segments he is illustrated as a responsible role model for the innocent Tails, often dealing advice to the fox when he gets into a difficult situation.

In this series, Sonic has been depicted as being quite the lady man (as referenced through the many female characters that he meets).
 * Sonic the Hedgehog (TV Series)

Sonic is a cool teenager with a big attitude. He possesses a lot of self-confidence and has a playful, yet never mean-spirited arrogance about him, which lets him have fun even in the face of danger and crack jokes while staring evil in the eye.

Sonic is very impatient when it comes to waiting and will actively seek out action, which makes him ignore manners and social customs and act before thinking. Because of his attitude, Sonic also sometimes come across as egotistical, but he is never selfish in his actions. Despite his flaws, Sonic is a good-natured person with a big heart and a strong sense of justice, and is fully devoted both to his friends and the Freedom Fighter cause.
 * Sonic Underground

Sonic is a wise-cracker of epic proportions and often cannot resist taking a stab at friend or foe alike. He has a big heart and is always willing to help someone in danger. Sonic can be, justifiably, arrogant about his speed and can have difficulties working in a team or taking the time to plan. He is extremely impatient ("I'm waaaaiting!") and would rather handle all the jobs himself than wait for others to take care of it. However he will admit if he made a mistake, though usually not when anyone can hear him. His love of Chili-dogs remains and he tends to have poor etiquette, much to Sonia's disgust.

He has a dislike of water and a near crippling fear of the ocean as he cannot swim, but his determination and bravery help him push through his fear if necessary. Above all he loves his brother and sister and can be very protective of them.

Additionally, as the leader of the team, Sonic tries his best to keep his siblings in line, and often gives orders on most missions. He thus proves himself to be a very strong and capable leader, but it can go to this head. When Luke Periwinkle attempted to drive a wedge between Sonic and his siblings, he told Sonic that he decided that he [Sonic] is a better leader and is to be crowned King of Mobius. Before then, Sonic even said himself that when he is coronated, he will assign positions on his court to his siblings.
 * Sonic X (Anime)

Sonic is a habitual daredevil who is honest, loyal to friends, keeps his promises and dislikes tears. He took the young Tails under his wing like a little brother. Even though he isn't intrigued by the marital proposals from Amy Rose, he seems to share her feelings. With Knuckles, he shares a friendly rivalry, but the two can be great teammates, though Sonic simply can't resist teasing him whenever he has the chance to. Even though he meets Chris at the beginning of the series, he quickly becomes his friend and treats him like a younger brother similar to Tails. He is mostly seen napping, running towards an adventure or stopping Dr. Eggman with his plans of world domination.

In times of crisis, he focuses intensely on the challenge as if his personality had undergone an astonishing change most of the time.

Despite of his positive attitude, Sonic displays some loneliness when he first arrived at Earth, believing that he was the only one being transported without his friends and feels partially sad about it. Sonic has also shown himself as a bit of a trickster, as seen when he was struck on a cruise with his friends, where he manipulated the others to return back by deceiving them that their loved ones at home were missing them.
 * Sonic Boom (TV Series)

Much like the wind, Sonic is free-spirited and always on the move. He has a passion for adventure and is very much a thrill-seeker, always looking for the next thrill, challenge, and triumph. For Sonic, speed is a way of life; he runs fast, thinks fast and even eats fast. Being addicted to speed and action, Sonic gets bored and restless during extended times of peace. In fact, Sonic cannot process the aspect of being restricted and being unable to move makes him extremely stir crazy. He acts on instinct and lives in the moment, though he is impatient, impulsive and tends to run headlong into trouble without a plan. Regardless, his heart is always in the right place. When being honest, he tends to be rather blunt.

Sonic's typical driving force is his immensely large ego, and he is usually laid-back, cool and carefree. Possesses a snarky tongue, he is likewise cocky, playful and often jokes around even in dire situations. When the situation calls for it though, Sonic can be serious and will immediately rush to aid those in dire need. Always courageous and heroic, Sonic is very benevolent with a strong sense of justice and fair play, being fully committed to helping out those in need at all times. Sonic also does not back down or give up, because he has an unwavering belief and faith in himself and his abilities. While having his own fair share of quirks, Sonic has a profound common sense that often makes him the "straight man" amongst his friends.

Though rather selfless when saving the Village, Sonic does come off as somewhat sensitive about his hero-status, becoming extremely jealous, defensive, and frustrated whenever someone else rivals his fame, or when the civilians turn against him. This mindset even led to him temporarily retiring due to how ungrateful the citizens were for his efforts. Even so, when the times really call for it, Sonic will forgo his opinions to help those in need. Sonic is also a true chili dog connoisseur who can identify the ingredients of a chili dog with one bite.

Sonic is noted to be strongly loyal towards his friends. Though he may not always show it, he cares deeply for his friends and will do anything for them. Early on though, Sonic was somewhat of a loner and cynical. While he was willing to work with his friends in times of need, he would show more interest in going out alone and would even take credit for what the team did collectively. With time though, Sonic grew to see how his team made him stronger and realized that his friends were his strength. Since then, Sonic has become a much more admirable team leader, being quick to ask for help and acknowledge their collective contributions, though he is still kind of snarky.

Appearance

 * Adventures of Sonic the Hedgehog

Sonic is a blue, anthropomorphic hedgehog with a light yellow muzzle and belly. His head and back are covered in spines, which are instrumental in his buzz saw attack. He always wears the same red and white pair of shoes, which are heat-resistant and necessary for his incredible running ability. He also wears gloves and seems to have conjoined eyeballs. Sonic is also able to disguise himself in different outfits to trick Scratch and Grounder for fun and humor.
 * Sonic the Hedgehog (TV Series)

Just like with Adventures of Sonic the Hedgehog, Sonic's appearance remains the same in this tv series.
 * Sonic Underground

Just like with the Sonic the Hedgehog TV series, Sonic's appearance remains the same in this tv series. But as a infant he seen wearing a yellow PJ suit, and as a child he was seen wearing a red T-shirt. However Sonic also wears a guitar necklace around his neck overall.
 * Sonic X (Anime)

Just like with the 2000 video games, Sonic's appearance remains the same. He has grown taller and that his eyes are more narrow.
 * Sonic Boom (TV Series)

Sonic retains most of the appearance from his 2005 appearance, but has a few physical and clothing differences. He is much slimmer, with longer arms and legs and more pronounced shoulders, giving him a lanky appearance. His hands are also noticeably smaller. Sonic's quills are also slightly messier, having some cowlick-like spikes that sticks out from his top and lower quills, and his arms are covered in blue fur, as opposed to being skin-colored.

For attire, Sonic wears a pair of white gloves with cuffs and a pair of red sneakers, which have white cuffs, grey soles, and a large, rectangular gold buckle on the top. Both of his gloves and sneakers have white sports tape around them, which is wrapped around his palms, the lower half of his arms and legs, and the heels of his sneakers. Finally, he sports a short brown neckerchief around his neck.

Speed

 * Adventures of Sonic the hedgehog

Sonic can run at extremely fast speeds, assuming he is wearing his specially designed Hi-tops. While his top speed is unknown, he can run fast enough to reach the opposite side of Mobius in less than four minutes and forty-five seconds.

Buzzsaw Curl Ball
Sonic is capable of curling into a ball and performing a buzzsaw attack which can cut through most objects (similar to the spin dash) though there are various materials that are too hard for him to penetrate such as nuclear forged steel and diamondium laced metal. Sonic is also an incredibly efficient burrower; by cutting into the ground while spinning, he can dig through the underground at such speed that he can burrow directly through Mobius in less than twelve seconds.

Disguise
Sonic is a master of disguise and often uses a variety of costumes to foil Robotnik's schemes; his disguises are made all the more effective thanks to the extreme gullibility and stupidity of Robotnik's minions.

Power Rings
He is also able to harness the forces of the Power Rings, which charges up his strength and super speed to such levels that he creates an explosion upon dashing off.

Adventures of Sonic the Hedgehog
The episode begins with Sonic and Tails being captured by Scratch and Grounder. While hanging upside down in a tree, Sonic decides to remind Scratch and Grounder how they all first met.

In a flashback, there is a gathering of Badnik bounty hunters. Dr. Robotnik called this group together to offer them an award of a billion Mobiums for Sonic alive or otherwise. Sonic is in the audience, but it takes everyone a long time to realize it. Robotnik eventually sicks all the robots on him. Sonic runs out and tricks each robot into a path of their own destruction.

Back at his lair, Dr. Robotnik decides to make two new robots for the sole purpose of catching Sonic. He throws many ingredients into a machine including a pair of rotten eggs. As a result, the machine produces Scratch. Thinking Robotnik is his mother, Scratch begins kissing Robotnik and licking his body. Annoyed, but not taking it too seriously, Robotnik clones Scratch with his robot making machine. Scratch pulls one extra lever which was not supposed to be pulled. The machine produces Grounder and right off the bat, the two start bickering about who is Robotnik's favorite. Robotnik dubs the two robots his Super Special Sonic Search and Smash Squad.

Coconuts watches from the bathroom. Coconuts is jealous of these new robots because he had been rejected by Robotnik and put on latrine duty. He vows to catch Sonic himself and win Robotnik's love.

Sonic and Tails are out running when they find a chili dog stand which is run by Coconuts in disguise. The stand becomes a large Robot that chases the heroic duo, but is eventually defeated. Similarly Scratch and Grounder try a number of clever plots to catch Sonic. Eventually they succeed in capturing Tails, thus Sonic gives himself up to ensure Tails' safety.

With Sonic and Tails captured, Scratch and Grounder call Robotnik to come and pick them up. Coconuts sneaks up on them and ties up Scratch and Grounder so as to take credit for capturing Sonic and Tails. Sonic convinces Coconuts to put Scratch and Grounder in the cage with him. Coconuts proceeds, but sure enough when he opens the cage, Sonic escapes and traps all three Badniks in the cage. he frees Tails and creates a dust storm making Dr. Robotnik unable to see when he flies in on his Egg-o-Matic. Sonic tricks Robotnik into landing on the cage and smashing up his own henchmen.

Back in modern day, Sonic ends the story and is still hanging from the tree. Scratch and Grounder don't like the story because they don't catch Sonic in the end. Sonic escapes the tree, then he and Tails run away.

After fuming about how much he hates Sonic, Robotnik's Deluxe-Highly-Callibrated-Hedgehog-ometer picks up Sonic's presence, being in the Marble Zone. He subsequently activates a Spring that launches Scratch and Grounder there. When they arrive, the Badniks chase Sonic and Tails, but they escape down a geyser which leads to a series of tunnels. Nevertheless, Scratch and Grounder decide to follow them.

Sonic and Tails find a cave full of gold and diamonds. They also meet a mole named Spelunk who thinks they want his money. He tries to blast them with a cannonball, but they manage to avoid it. The cannonball ends up trashing Scratch and Grounder. Sonic and Tails come across minecart tracks which they assume will lead them out of the underground tunnels. They run along the tracks, but are stopped by an angry Spelunk coming straight at them in a minecart. Sonic and Tails try to outrun him when they notice a family of turtles crossing the tracks. Sonic dresses as a crossing guard and stops Spelunk, allowing the turtles to cross the track. Once the turtles are safe, Sonic lets Spelunk's minecart pass. He and Tails once again attempt to leave the tunnels.

Running up a flight of steps, Sonic and Tails have almost reached the surface. Spelunk, realizing he had been tricked by Sonic, pulls a lever which smooths out the staircase. This causes Sonic and Tails to slide back down the steps and into a cage. The bars are made from diamondius, the hardest substance on Mobius, so Sonic cannot cut through them.

Scratch and Grounder return with Dr. Robotnik in drilling vehicles which they plan to use to obtain Spelunk's loot and capture Sonic simultaneously. Angry that Robotnik is after his treasure, Spelunk blames Sonic and opens a pit in the cage where Sonic and Tails are being kept. Scratch and Grounder use dynamite to blow a hole in the ground. The cave crumbles and a large diamond breaks the cage open, freeing Sonic and Tails. Robotnik, Scratch and Grounder fall into the pit.

With the cave crumbling, Sonic decides to escape, but Spelunk doesn't want to leave his treasure behind. Sonic saves Spelunk from being crushed by a falling boulder. He is touched that Sonic saved him, so he returns the favor by leading them outside the tunnels to safety.

Robotnik, Scratch and Grounder, who have somehow escaped the pit, begin to steal Spelunk's treasure. Sonic, who is dressed like an IRS auditor, informs Scratch and Grounder of all the paperwork and taxes they have to deal with for acquiring this large amount of treasure. The initials for the taxes spell 'You are so stupid'. Sonic binds the three villains in calculator paper and sends them up a conveyor belt into Robotnik's Egg-o-Matic. Spelunk then pours gunpowder on the conveyor belt and lights it with a match. Sonic quickly removes the treasure from the Egg-o-Matic before the gunpowder explodes and sends Robotnik, Scratch and Grounder blasting off.

Spelunk says he's never met such greedy, miserly jerks before in his life, but Sonic and Tails point out that he is one himself. Spelunk thanks Sonic for showing him the error of his ways and he decides to use his fortune to buy chili dogs for Sonic and Tails.

When Sonic saves a very pretty girl hedgehog named Breezie from Scratch and Grounder, she flirts with him. Then Breezie gives Sonic a kiss and love hearts appear in Sonic's eyes. Sonic is unaware that Breezie is actually one of Robotnik's robots, sent to distract him while he proceeds to destroy the underground wells of Mobius with his new Egg-o-Matic Tunnelizer and Town Terrorizer. Meanwhile Sonic returns as all the snow melts off him. Tails lets Breezie see how tired Sonic is. So Breezie strokes Sonic's head. Then Sonic runs along to heat up Breezie's chili dog.

After Breezie throws Tails in a rushing river, Scratch and Grounder come to team up with Breezie and make plans to eleminate Sonic. Tails makes it back and spies on the three robots as they plot their traps. Tails rushes off to warn Sonic and tell him about Breezie, but Sonic is too twitterpaited to listen. After Sonic writes a romantic poem for Breezie, she starts to develop feelings for him. But it is too late, Sonic runs to the robots' big magnet. Fortunately, Breezie frees Sonic, and they escape.

Breezie tells Sonic that she is a robot and of Robotnik's plans to drain the reservoir. Sonic stops Robotnik by attaching a bungy cord to his Egg-o-Matic Tunnelizer and Town Terrorizer. Robotnik springs into the opposite direction yelling "I hate that Hedgehog!".

Sonic is sad, but Tails brings him a note from Breezie which says she hopes they'll meet again some day.

Dr. Robotnik flies to the Sloth's home planning to use them as bait to lead Sonic into a trap. He damages their house with Scratch and Grounder. Rocket the Sloth sees Robotnik escape and sends a Morse code message to Sonic for help. Back at Robotnik's fortress, the evil Doctor shows Scratch and Grounder his Subatomic Slow Go Beam Weapon which can shoot a slow motion beam that will put Sonic into sloth motion. However, his mind is still accelerated (when Sonic pulls on Scratch's tail feathers, Jaleel's grunts for Sonic were recorded at normal speed). Sadly, it doesn't last long; the effects wear off in one hour.

Sonic and Tails arrive at the Sloth's home and repair the damage caused by Dr. Robotnik. Rocket sits in a tree with a gong, on the look out for danger. Scratch and Grounder come and begin firing slow rays. Sonic figures out what the ray does. Robotnik shows up and Scratch and Grounder accidentally zap him again. Robotnik leaves for an hour. Scratch and Grounder set a trap for Sonic, by having Scratch hide in a tree while Grounder hangs from a branch disguised as a distressed Sloth. Sonic stops to help the sloth, allowing Scratch time to zap him with the slowness ray, slowing down his molecules and his voice. Sonic slowly tells Tails to go warn the sloths. Scratch and Grounder capture Sonic and take him to a cave where they put him in a cage and call Robotnik to tell him their good news.

Back at the Sloth's home, realizing Rocket can't help him, Tails goes to save Sonic himself.

Back in the cave as Scratch and Grounder taunt Sonic, Tails steals the slow ray and threatens to shoot Scratch and Grounder. Grounder knocks it out of his hands, breaking the crystal that it runs on. Tails takes the slow ray and retreats to the Sloth home.

Back at the Sloth's home, Rocket uses the slow ray to make him and his family super fast. Tails and the four speedy sloths rush off to save Sonic. The Sloths roll into balls like Sonic, they bounce around and hit Scratch and Grounder. Tails zaps Sonic with the ray and he is back to his fast self. Sonic quickly takes care of Scratch and Grounder. Robotnik comes and Tails zaps him with the ray making his Egg-O-Matic go super fast. Speeding beyond control, Robotnik crashes into a mountain.

In a town, Smiley is using underhanded techniques to gain all the material assets of a group of Gambler Sheep. Once they have nothing left to lose, Smiley takes them as slaves to work on building Dr. Robotnik a sphinx in the desert.

Smiley has a cheating robot (or High Voltage Flimflammer as Sonic calls him) who plays a game with a pea under one of three nut shells. Sonic comes to help the sheep win. Sonic's eyes are fast enough to keep on the pea and he wins every time. The Flimflammer malfunctions and blows up. Sonic wins back all the sheep's things. In order to get them back, Smiley lures the sheep to Robotnik's Casino Night Zone. The sheep, having not learned their lesson, go to the Casino Night zone and gamble until they lose everything again.

Sonic and Tails go to the Casino Night Zone where Sonic disguises at a maintenance worker and resets the machines to make the sheep win. The Sheep get a lot of money. Sonic leaves Tails in the nursery with a pig lady while he runs off to take care of Scratch and Grounder.

While Tails is playing in the Nursery ball room, the Pig Lady reveals that she works for Robotnik and has Tails fall into a trap. Robotnik puts Tails in a cage. Tails gets mad and calls Robotnik a "Crum-bum," and when Robotnik comes close, Tails ties Robotniks' mustache to the bars of his cage. Robotnik eventually gets free.

Sonic returns to Casino Night Zone and cannot find Tails. Smiley tells him Tails is captured by Robotnik and to ensure his safety Sonic has to lose a race to Grounder.

At a large Stadium, Scratch announces the race and all the sheep bet on Sonic. Sonic sadly walks in the race, disappointing all the sheep. Bragging about his imminent victory, Grounder tells Sonic that Tails is in a cage underneath the stadium. Sonic tunnels underground and saves Tails, tunnels back up and wins the race, but Robotnik has already taken the sheep as his slaves. Sonic runs to the desert and sets Louis and the sheep free. He then re-designs Robotnik's sphinx to look like himself, after which the Sphinx looks at Robotnik and winks. This upsets Robotnik, making him cry.

The sheep then ask Sonic if they could be good freedom fighters to which he considers risky. The high stakes would be "Mobius free of Robotnik".

Sonic the Hedgehog (TV Series)
A sleek black aircraft descends through the clouds to planet Mobius. Doctor Robotnik, the planet's absolute ruler, is returning home to Robotropolis, a sprawling cityscape choked with the smoke of innumerable factories. Robotnik strokes his robotic bird, Cluck, saying "I do miss the beauty of this place when I'm away." The aircraft settles on a landing platform on one of the tallest buildings, where Robotnik's toady Snively waits to greet him. As Robotnik enters the control room, Swat-bots open the door to let him in, but when Snively tries to enter the Swat-bots close the door and Snively bumps into the closed door, and the two Swat-bots chuckle, since he fell for their prank. In the control room, Robotnik demands to know if there has been any hint of his nemesis, Sonic the Hedgehog. Snively is too cowardly to admit that there has been none, and stammers for a while until an emergency appears on monitor 10. Scanners have detected one of Sonic's group of Freedom Fighters: Snively recognizes him as the young Tails, usually accompanied by Sonic. Robotnik says to capture him. "Perhaps his cries will flush out the hedgehog!"

Meanwhile, Tails is out picking flowers for Princess Sally when he spots one of Robotnik's Buzz-Bombers bearing down on him and he flies away. Not far away, Sonic demonstrates a new rock song for his pal Rotor Walrus. Sonic wants to impress Sally, but Rotor says she won't like it. She'd prefer a softer song, like a ballad, but Sonic can't stand ballads. Suddenly, they hear Tails crying for help. Sonic speeds to the rescue, whisking Tails out of the way of the Bomber's sting blast, which ricochets off a rock and destroys the Buzz-Bomber! Rotor draws their attention to a floating eye camera. Sonic and Rotor use the opportunity to insult Robotnik, who is watching from a monitor, but Tails simply waves and says "Hi mom!" Before they go, Robotnik swears that he'll have both Sonic and the Power Rings in the palm of his hand before the day is through. The three Freedom Fighters are not impressed, and Sonic zooms away with his friends in tow.

Soon after, the three heroes arrive at the secret entrance to their home at Knothole. Tails enjoyed riding with Sonic, but Rotor feels decidedly queasy. Sonic and Tails ride together down a twisting slide that takes them into Knothole and drops them in a haystack. Moments later, Rotor follows, landing on top of them.

Some time later, the Freedom Fighters (Sally, Bunnie, Antoine, and Rotor) attempt to repair some catapults. Bunnie, a cyborg, does the heavy lifting and is annoyed by Antoine's habit of "supervising" while doing no work of his own. Antoine also flirts with Princess Sally, who rebuffs his advances. Sally uses a computer to determine why the throwing arms of the catapults keep breaking, and finds the answer just as Rotor deduces it all by himself: the cotter pins are made of wood, but need to be metal in order to take the extra payload. Just then, Sonic arrives. When Sally explains that they need metal cotter pins, Sonic takes Rotor and says they've "gotta do the Power Ring thing!" He, Rotor and Tails go to the Lake of Rings, and as they watch a Power Ring rise out of the water. Tails wonders why only Sonic can use the Power Rings, so he explains: his Uncle Chuck invented them to help Sonic take down "dorks" like Robotnik.

While Sonic waits to get an example cotter pin from Rotor, Tails decides that he's going to head to the "big city". When Sonic catches him up, he is fighting a tree. Sonic explains that the big city is too dangerous for a kid like Tails: it's swarming with Swat-bots, who are just waiting for a chance to roboticize Tails! Tails points out that it's a long way back to Knothole and he could be captured by a Buzz-Bomber, so Sonic agrees to let him tag along as long as Tails stays hidden in his backpack and guards the Power Ring.

In Robotropolis, Sonic and Tails narrowly avoid detection by Swat-bots. They reach one of Robotnik's factories, where they manage to find the cotter pins in a pile of debris. However, Tails spots a line of worker robots walking into the factory. Sonic explains they used to be people, until Robotnik roboticized them. Tails asks if Uncle Chuck is there, but Sonic doesn't see him. Sonic misses Chuck, as well as his old dog Muttski. Suddenly, Tails sees a mean-looking robot guard dog: it's Muttski! He may look vicious, but Sonic believes Muttski won't hurt him because Sonic is his best bud. He calls out to his dog, only to have Muttski pounce and bite his tail. Sonic is disappointed, since after all he put Muttski through four years of obedience school. "Bad dog! You sit, you stay, you don't bite! Understand?" Suddenly, Muttski does just that - his eyes turn from red to white and he sits, and starts wagging his tail. He's Sonic's friend again! He licks Sonic's face and Sonic promises to turn him back to a real dog by putting him back through Robotnik's robo-machine. Unfortunately, Muttski's old personality doesn't stay long, and he quickly turns back to a savage, red-eyed guard dog. Sonic flees rather than fight his friend.

While escaping from some Swat-bots in the city, Sonic and Tails dive into an air vent. It turns out this vent leads to Robotnik's control room, where Robotnik is explaining his latest plan to locate Knothole Village and eradicate the Freedom Fighters. His Buzz-Bombers will fly over the Great Forest, spraying it with a new chemical that Robotnik invented, which will kill every tree, exposing Knothole's location. He also has a "hedgehog-seeking missile" prepared, in case Sonic should interfere. Just then, Tails sneezes with such force that he and Sonic both fall into the control room. They quickly escape the building, however, and Sonic uses the Power Ring to increase his super-speed even further and defeat the Swat-bots sent to capture him. He and Tails speed back to Knothole.

Sonic quickly warns everyone about Robotnik's plan, but luckily Sally has a plan of her own. When the Buzz-Bombers approach, the Freedom Fighters set up the now fully-functional catapults in a line at the edge of the Great Forest. However, Sally says that the range is limited, and Sonic volunteers to lure the Buzz-Bombers in range. Using one of the catapults, Sonic shoots himself towards the incoming Buzz-Bombers, leading them to launch the hedgehog-seeking missile. However, Sonic is able to turn this against them by leaping on top of the tanks of Robotnik's defoliating chemical. The missile hits the tanks, which fall to the ground far below. Robotnik orders the Buzz-Bombers to attack Sonic, who leads them in range of the catapults. Sally gives the order to fire, and they pelt the Buzz-Bombers with water balloons, short-circuiting them. Robotnik demands through the radio that they keep attacking, but the Buzz-Bombers have had enough, and flee. Robotnik decides to take his frustrations out on Snively.

Safe once again, the Freedom Fighters celebrate, and Sally says that Sonic was "really great today!"

In Robotropolis, a green security SWAT-bot is carried by floating platform to one of the industrial building's elevators. The elevator takes the transport downward in the elevator, the floor indicator counting upwards until it shows "51." The doors open and the transport enters a large room, where it faces a yellow security bot that transmits the message "Hall secure." In an air duct, undetected by the robots, Sonic the Hedgehog speeds through until he stopped at a vent, calling for Antoine and Cat to hurry up as they pant down the duct after their friend. When they arrive,

Sonic checks the room, only to come face to face with the green security bot. The three Freedom Fighters jump back against the wall as the transport removes the vent and points a light into the duct. The security bot's windshield opens to reveal that Princess Sally was commanding it. Greeting her fellow Freedom Fighters, she jumps from the transport and, accompanied by Sonic, enters a robotic plane. Using Nicole, Sally aims to hack into Robotnik's mainframe computer in order to reprogram the plane's launch data. While working, however, she receives a message addressed to "Bean". Sally's father used to call her Bean when she was little, and she immediately starts tracking down the source of the signal, believing that he may still be alive! The signal apparently originates from the Dark Swamp.

Back in the air vent, a nervous Antoine leans against the grill, toppling out of the duct and straight in front of a security Swat-bot! Ant dives back into the duct. Realizing that their cover is blown, Sonic goes to distract the Swat-bots while Sally makes a dash for the duct. When she is safe, Sonic makes his own escape. However, a single Swat-bot follows Sally, Ant and Cat into a duct. Cat, who is bringing up the rear, spots it and decides to lead it away from the others. Only when Sonic meets up with Sally and Antoine at their preset rendezvous point do they realize that Cat is gone. Sonic realizes he must have been captured, and wants to go back to save him. Sally, convinced that the signal was from however, says that she is going to go to the Dark Swamp to find him, and she'll take Antoine with her. Sonic says he'll catch up once he's rescued Cat, and speeds back to Robotropolis.

Meanwhile, Snively reports back to Doctor Robotnik, who orders the air ducts sealed up. Snively does have some good news. They have captured a Freedom Fighter: Cat! Robotnik wants Cat to tell him the location of Knothole, but Cat refuses to talk.

Some time later, when Sonic arrives back in Robotropolis, he sees Cat being taken by a Swat-bot to a detention center. Although Sonic breaks in and reaches Cat's cell, Cat tells him that Robotnik's surveillance detected Sally heading for the Dark Swamp, and that Sonic has to go save her. Sonic doesn't want to leave Cat, but Cat says it doesn't matter. As guards show up, Sonic escapes, promising he'll be back.

A Surveillance Orb follows Sally and Antoine through the Dark Swamp. Antoine is terrified, but tries to dismiss his trembling as shivering from a cold he as caught. He wants to go back to Knothole, but Sally isn't willing to give up. She asks Nicole about whether there are any structures in the Dark Swamp, and Nicole identifies only one: Ironlock Prison. When Sonic arrives at the swamp, he is also detected by a camera, leading Robotnik to launch a Stealthbot. However, it is easily defeated by Sonic, who turns its own missile against it.

Sally and Antoine arrive at Ironlock Prison and try to cross the rickety drawbridge over a deep chasm. Although they make it to the other side, the bridge collapses, leaving them stranded. They explore the prison, finding a scrap of King Acorn's cloak—Sally now has proof he was there!

Sonic, Sally, and Antoine search Ironlock for information regarding the King. At this point, Sonic catches up to them, having been following their footprints in the swamp mud. He leaps over the chasm and finds Sally and Antoine walking through the prison cells. Sally shows him what they've found: an ancient computer. Sally realises that her father must have sent her the message from this computer. When she accesses it, using "Bean" as the access code, she receives a message: "Bean, Check Sub-ter file. Impossi—" The message is incomplete, but at least Sally now knows he is alive. When she checks the computer's Sub-Ter file, she finds it contains schematics of the underground tunnel network throughout the whole of Robotropolis! As she tries to get Nicole to transfer the data to a holographic disk, the walls start to crumble and all three heroes are sent through a trapdoor into the sewer system below. They then see a red light in the distance, within the darkness of the only passage out of the sewers, and Sonic decides to go and check it out. But when he comes back, he states that they cannot go that way, as the red light turns out to be the glow of the eye of a giant one-eyed monster, which then attacks Sonic and his friends. But Sonic manages to defeat it by using a Power Ring, revealing that it is merely a robot.

With one obstacle out of the way, Antoine brings up another: how are they supposed to get out of this place? Bringing up the holographic map on Nicole, Sally gets a great idea. She leads the others down one particular tunnel, straight into Robotropolis. Using the secret tunnels, they access the Stealthbot hangar bay, and Sally reprograms every single one. While Sally and Antoine head back to the usual rendezvous point, Sonic has one last job to do: rescue Cat. But when he gets to Cat's prison cell, Cat has gone! Saddened by the loss of his friend, Sonic makes his escape. He is detected by Robotnik's surveillance, leading the dictator to launch all of his Stealthbots.

Back at the rendezvous point, Sonic and the others see the Stealthbots launching. Taking out a Surveillance Orb from his backpack, Sonic points it at the Stealthbots. When Robotnik sees the feed, he is confused and orders the Stealthbots to be recalled. However, as Snively presses the recall button, the Stealthbots all self-destruct! Turning the camera on himself, Sonic gives Robotnik one last message: "That was for Cat!"

After trying to detonate one of Robotnik's machines, Sally gets captured by Dr. Robotnik's Swat-bots. Sonic tries to go back, but Bunnie tells him he needs a power ring if he's going to save Sally. Meanwhile, Robotnik creates a clone of Sally to use to try to destroy Knothole. Sonic gets the power ring the next day and rescues Sally, but doesn't realize that it was the clone that Robotnik created. Sonic and the cloned Sally returned to Knothole. Tails found out he didn't get the "Funny Kiss" (on the nose) that Sally usually gives him. Then the clone reads a book to Tails and asks her to do the scary witch voice but refused and walked off. Sonic then, finds out that the SWAT-bot factory was still online and decides to go back and redo the mission. While in bed, Tails sees the cloned Sally and he sees the eyes glow red and finds out that it wasn't the real Sally. Bunnie wakes Sally up and showed her the ruined carrot crops, and Tails thinks it was the "Fake" Sally who did this during the night. Before going to the factory, Tails tries to tell Sonic that it wasn't the real Sally, Sonic thought Tails had a nightmare and ran off.

While at the SWAT-bot factory, Sonic does the special handshake that he and Sally do, and finds out that Tails was telling the truth, that it wasn't Sally. After subduing her, the clone shows Sonic the way to the Real Sally, who saves her before she was robotocized and run back to Knothole while putting the clone in Sally's place inside the roboticizer, overloading it and destroying the factory. Back in Knothole, Sally finds Tails sitting by the log and gives him the "funny kiss", proving to Tails that she's the real Sally (Adding more proof with the "scary witch voice"). She attempts to prove it by giving Sonic a kiss, but this makes Sonic claim that she's fake so he grabs Tails and runs off.

While spliting up into teams, Sonic, Sally, Antoine, Bunnie, and Rotor are forced to flee Robotropolis in mid-plot. Their rendezvous is a train station, where Sonic's roboticized Uncle Chuck boards a departing train. The Freedom Fighters follow the train to the crystal mine to try to rescue him. Unsurprisingly, he is not the hedgehog he used to be, but Sonic temporarily fixes that with a power ring. Returning to Knothole with the freed Uncle Chuck will have to wait, however. The robots are excavating a powerful crystal, which will further Dr. Robotnik's goals and wreak havoc across Mobius. This leads to Chuck going back to robotic form, while telling Sonic to leave Robotropolis while he still can. But Sonic protests so Bunnie brings him on the train herself against his will of not wanting to leave his uncle again. Back at Knothole Sonic is comfort by Sally and Bunnie telling him that they will get Chuck back, to which sonic agrees to.

The Freedom Fighters embark on an outlandish mission: to find magical scrolls which may hold the key to unlimited power.

Sonic Underground
This series explains the origin of Sonic and his siblings and how they banded together to reunite with their mother. Queen Aleena tells the story of how Dr. Robotnik took over planet Mobius and how she had to give up her three children–Sonic, Sonia, and Manic–to fulfill a prophecy that one day the siblings will be able to rise against Robotnik's rule and restore peace to the planet. This episode also shows where Sonic, Manic, and Sonia end up living. Sonia is left on Lady Windimire's doorstep. Sonic lived with two Mobians who ended up getting roboticized, forcing Sonic to live with Uncle Chuck. But when Manic is left on a doorstep, he is kidnapped by thieves, who raise him in their ways. The Hedgehogs find each other and see their guardians roboticized, and discover more about their mother.

The Hedgehog siblings begin to learn the important lessons of what it takes to be a Freedom Fighter. The Oracle provides teachers to guide Sonic, Manic and Sonia to develop the necessary skills to recognize the power that comes from within. The Hedgehogs also discover the hidden magical force of the power medallions as they grow to understand that teamwork will serve them best in averting the dangers that await them.

must end their training early when Dr. Robotnik threatens the Oracle and takes a member of the resistance hostage. During the rescue mission, the Hedgehogs fall into trouble and begin to place blame upon each other for everything that has gone awry. Queen Aleena then intervenes with an important message for her children that they must learn to work together and derive strength from their willingness to help others.

Argus, a captain of the Queen's guard, is captured by Sleet and Dingo before he can reach the secret rendezvous where he was to meet Queen Aleena. While listening to a scanned radio message, Sonic, Manic and Sonia overhear that a queen's guard has been captured and roboticized. The hedgehogs then begin their pursuit to recapture Captain Argus from Dr. Robotnik and get the information revealing the secret meeting place where they may be reunited with their beloved mother.

Sonic, Sonia and Manic return to their birthplace, Mobodoon, a beautiful, festive town. The homecoming is interrupted when Sleet and Dingo arrive to collect back taxes by order of Dr. Robotnik. Because Mobodoon has no form of currency to pay this bogus debt, Sleet and Dingo decide to raid the village and steal its most precious monuments, including the powerstone, which is the center of Mobodoon's vitality. It is up to the Hedgehogs to get the powerstone back and restore their former home to its previous blissful state.

Season 1
One day, Sonic attempted to rescue Cream and Cheese from Dr. Eggman as well as foil the doctor's latest plot to control the world with the power of the seven Chaos Emeralds. Unfortunately, an accident initiated Chaos Control, which transported Sonic, his friends, Dr. Eggman and a few others to Earth. Seemingly separated from his friends, Sonic was astonished from meeting the human inhabitants of the world. After outrunning from the police officers and the Speed Team, Sonic befriended Christopher Thorndyke, who rescued him from drowning in a swimming pool. The next day, Sonic discovered that the military had captured Cream and Cheese for research at Area 99. With the help of Chris and his grandfather Chuck Thorndyke, Sonic infiltrated Area 99 and rescued the duo. Despite the security, Sonic, Cream and Cheese escaped from there to safety with some help from Tails, who sabotaged the facility's security system.

After that, Sonic left for a care-free journey. After enjoying some thrills, Sonic eventually heard the news of Dr. Eggman attacking Station Square with his E-23 Missile Wrist in an attempt to establish his Eggman Empire. After he reached Eggman, Sonic destroyed Missile Wrist, and he and his friends escorted Amy and Knuckles back to Chris' home. When Sonic heard the discovery of the first Chaos Emerald at a construction site, he rushed there but got ambushed by Dr. Eggman's E-11 Beacon, which bounced the hedgehog around, rendering him helpless. However, Sonic managed to destroy Beacon with the help of Tails and Amy in time to rescue a free-falling Chris who had gotten the Chaos Emerald. Soon after, Sonic was challenged by Knuckles to a showdown at Silver Valley. Sonic mainly toyed with Knuckles during the fight but discovered that Tails, Amy and Chris were held hostage in Eggman's E-47 Pumpty. Eventually, Knuckles realized that Eggman had tricked him and worked with Sonic to rescue Tails, Amy and Chris and destroy Pumpty.

Sometime later, Sonic took off to Chris' school, wondering why Chris had not shown up home when his parents had returned, only to discover that Chris was being held at school along with his classmates by Dr. Eggman and E-51 Intelligente. Sonic, however, was able to destroy Intelligente and reminded Chris to return home.

Later on, Sonic overheard Tails and Amy discussing about Cream while he noticed a poster displaying a small lake with flowers. Sonic then took off and sought out the aforementioned location and he returned back home with a bunch of flowers from there for Cream. Sonic later comforted Chris after Chris got yelled at by Cream.

When Eggman began sucking up satellites in outer space using E-90 Super Sweeper, Sonic and Tails tried to stop the robot while high in the sky but it was too powerful to handle with the Tornado 2. During the following day, Sonic, Tails and Chris got ready to take down Super Sweeper using the newly-crafted X Tornado. The fight was taken into outer space where Sonic was frozen solid, but with Tails and Chris' help, Sonic was thawed out and destroyed Super Sweeper.

When Sonic declined to go with his friends to the Emerald Coast, he left on his own. However, when he learned that Eggman terrorized the resort with his E-38 Octoron and E-39 Quizon robots, Sonic headed there and fought the robots with Amy's help. Amy then tried to give Sonic a bracelet which serves as a good luck charm to protect him in the water, but Serpenter appeared and destroyed the bracelet. While Sonic fought the robot, he was left in surprise when Amy started destroying Serpenter and then knocked Eggman into the water, but she slowly sank. Knowing that Amy was in danger, Sonic jumped into the water and was able to rescue Amy.

After a while, Sonic was called to action when Dr. Eggman challenged Sonic and his friends to a winner-takes-all baseball game where the winner could claim the newly found Chaos Emeralds at Diamond Stadium. As Sonic and his team were able to edge into the lead, Eggman commanded one of his E-21 Ballios to attach its head onto Sonic, threatening to kill Sonic if the head explodes but Knuckles saved him. Regardless, Eggman still escaped with the Chaos Emerald.

Later on, Sonic went out with Tails and Chris in order to find the third Chaos Emerald when they got a lead, but found nothing and went back home. A while afterwards, Sonic was napping when he heard that the President was assaulting Eggman's base and discovered that Tails, Amy, Chris and Frances were gone and that they were in trouble at Tingalin Villa so Sonic sets off to find them.

Sonic eventually found his friends being assaulted by Eggman with his E-35 Funfun. Sonic disabled Funfun while Tails unearthed the third Chaos Emerald, only for Eggman to appear and steal the Chaos Emerald before taking his leave. However, Sonic and the others vowed to get the Chaos Emerald and chased Eggman to his base on the X Tornado. After evading an initial assault, Sonic smashed into Eggman's base where he faced Eggman in his new robot, E-18 Guerra-Hard. Sonic was initially overwhelmed by the robot as it was powered by two Chaos Emeralds, but Sonic still destroyed the robot while reclaiming the two Chaos Emeralds and used them to trash the base. The base exploded shortly afterwards, but Sonic escaped in the nick of time. The citizens of Station Square, who have been watching this, then hailed Sonic as the hero.

Season 2
After his victory at Eggman's base, Sonic was invited by the President to the White House for a party but Sonic declined as he promised to take Helen to an island said to have beautiful flowers. As Sonic and Helen began traveling towards the island, however, they were constantly ambushed by military forces as they were ordered to capture Sonic but every time, they managed to escape. Sonic and Helen finally arrived at an a field full of beautiful flowers and were adorned by its sight. The military forces chased Sonic and Helen again until they were cornered, but Sonic was able to escort Helen and himself to a helicopter and together, they flew towards the White House to meet the President. After meeting the president, Sonic is seen outside at Helen's house, sitting on a tree hearing her tell her parents about the adventure he had with her earlier.

Sonic encountered Eggman again when he launched the Egg Fort to attack Station Square. Sonic stopped an army of E-42 Torole and then tried to reach the Egg Fort but failed. However, the X Tornado arrived, and Sonic and his friends lured Eggman away from Station Square where Sonic then finished off the Egg Fort. Off to enjoy a vacation, Sonic and his friends then flew over to the Sapphire Sea where they discovered a Chaos Emerald located underwater. There, they uncovered the emerald but Eggman ambushed Sonic and his friends with E-57 Clurken. Sonic was initially unable to stop Clurken underwater but with the help of Sam and Tails, Sonic got to the surface and destroyed Clurken, allowing him to continue his vacation.

Sonic, along with Tails and Chris, flew on the X Tornado to a savannah but were attacked by Eggman. Sonic destroyed Eggman's Egg Fort but was separated from his friends. While running on his own, Sonic was ambushed by E-65 Gorru-Gaooh. As the fight continued to a construction site, Sonic was able to exploit E-65's flaws and defeated it.

Later, Sonic and his friends came to watch Lindsey starring a film production, but when Sonic explored the castle, he discovered a talisman before finding his friends being attacked by ghost hands and was imprisoned within a wall with them when trying to rescue them. With Amy and Chris' help, Sonic broke free and rescued his friends while fighting back their kidnappers, King Boom Boo and his Booms minions, before Sonic and his friends escaped from the castle to safety.

To relax from their adventures, Sonic and his friends went on a cruise to the glaciers, but Sonic was unwilling to enjoy himself and schemed numerous attempts to get off the cruise but failed. As Sonic and his friends arrived at the glaciers, they were attacked by Dr. Eggman in his new flying fortress, the Egg Fort II. Sonic had trouble stopping Eggman at first but when advised by a senior to relax, Sonic regained his confidence and after Eggman was defeated, Sonic finally decided to enjoy himself on the cruise.[21] After their vacation, one late night, Sam Speed arrived at the Thorndyke Mansion to issue a race against Sonic but Sonic refused. Eventually, after a long process of persuasion, Sonic agreed to race Sam. Throughout the race, the competitors were neck and neck until they both neared the finish where Sonic won by a landslide.

Sonic and his friends went on another vacation at Mr. Tanaka's homeland at Japan, where Sonic explored the city on his own. After this, Sonic encountered Dr. Eggman, Decoe and Bocoe on E-66 Da-Dai-Oh who attacked Sonic, but the hedgehog defeated Dr. Eggman and his lackeys again. He then aided Chris, Tails, Cream and Frances to filter mud out of a lake at a nearby Chao colony.

Later, Sonic joined with his friends on a trip to Filmdom City to see Nelson and Lindsey's wedding anniversary. Upon greeting Nelson, Sonic discovered that his Chaos Emerald was reacting to Nelson's Chaos Emerald which he had bought to surprise his wife, causing a violent electromagnetic reaction. The situation got worse when Eggman attacked Sonic and his friends with E-74 Weazo but Sonic, with the aid of Knuckles, managed to beat the robot and saved his friends and the Thorndyke family although Eggman got away with the Chaos Emerald.

A while later, Sonic and Amy were attacked by Eggman and his E-88 Lightning Bird. Lightning Bird kidnapped Amy but Sonic damaged the robot and rescued Amy. Unbeknownst to Sonic, however, a circuit from the robot entered his ear, leaving Sonic constantly picking his ear to get it out. The next morning, when Mr. Tanaka operated a remote, the circuit activated, causing Sonic to run uncontrollably without being able to stop. Sonic's friends tried numerous attempts to catch Sonic and discover what happened to him but all their plans failed. Later, Sonic found Amy attacked by a damaged Lightning Bird and destroyed it. In the process, the circuit finally slid out of Sonic's ear, allowing Sonic to be himself once again.

Sonic sets out with his friends once again to find the seventh Chaos Emerald but had no success. Later that night, Sonic went for a run but was stopped by Chris who wanted to tell Sonic if he was homesick as he and his friends had stayed on Earth for a while but the hedgehog did not mind and resumed his run. When he returned home, he and his friends that discovered Chris had taken their four Chaos Emeralds so that Sonic and his friends could return home. Figuring out what Chris meant earlier, Sonic took off to look for him. Arriving at the forest where the Egg Fort II was just about to take off, he spotted Knuckles who told him Chris was held captive at the Egg Fort II along with the Chaos Emeralds and chased after the flying fortress.

Sonic discovered that Eggman was flying over to E-77 Lucky who had found the seventh Chaos Emerald and stopped him from reclaiming the emerald. Suddenly, several G.U.N Beetle robots appeared to attack Eggman despite Sonic trying to tell them that Chris was trapped inside the Egg Fort II. In the ensuring battle, Lucky was sent flying into the air and Sonic saw the Egg Fort II moving towards him. Using the Beetles, Sonic rescued Lucky who then gave him the emerald. He then turned his attention towards the Egg Fort II which transformed into E-99 Eggsterminator and engaged it in a fight. With the six Chaos Emeralds' energy however, the Eggsterminator was able to beat Sonic unconscious and dropped him into the ocean. Thanks to Chris though, the six Chaos Emeralds fell into the ocean and Sonic used all seven Chaos Emeralds to transform into Super Sonic. Using his enhanced powers, Sonic destroyed the Eggsterminator and rescued Chris as a new Chaos Control automatically occurred. Chris pleaded to stay with Sonic but Sonic disappeared. Quickly though, Sonic returned and it was revealed that the Chaos Control teleported Angel Island to Earth.

Trivia

 * There is a genome named Sonic hedgehog.
 * According to Yuji Naka, Sonic will not ever get married as he cannot picture Sonic in a marriage and with children.
 * Sonic's favorite thing to do in his free time is running.
 * Originally, Sonic was intended to have visible fangs in his Japanese artwork, though they were removed when he was given a more Americanized design for his US artwork in order to "soften him up" slightly. Even though he still possesses fangs, they are only visible when he opens his mouth (this is mainly noticeable in Dreamcast titles such as Sonic Adventure and Sonic Shuffle, but became less obvious after Sonic Adventure 2). Previously, his fangs were supposed to be visible even when his mouth was closed.
 * In the Japanese versions of the anime series and games, Sonic proves that he knows more English than any of the other characters, as he is the only one who speaks English many times in the games. This may be due to the fact that the English language is considered "cool" in Japan, and it therefore makes sense to have the "coolest" character speak many English lines, since his current Japanese voice actor Junichi Kanemaru, wanted him to.
 * Sonic makes a cameo appearance in the Disney film Wreck-It Ralph, in which he is voiced by Roger Craig Smith. Eggman also makes an appearance in the film, thus marking the big screen debut for both characters. Much like Eggman, Sonic's design seems unchanged from his current design in the game series.
 * In Adventures of Sonic the hedgehog, Sonic is not afraid of water and can swim quite well.
 * In Adventures of Sonic the hedgehog, Sonic is allergic to a certain flower and if it touches him, he will swell up like a balloon.
 * Sonic's appearance in the first 1993 cartoon series was largely based on the version seen in the Western box art of the existing Sonic games, which lead to a number of diversions from his established Japanese design. Such changes include a mowhawk-like single row of spines on his head as opposed to three rows, a two-spined single row down his back as opposed to two single-spine rows, and the lack of a tail. This design would be carried over into the subsequent western Sonic cartoons, Sonic the Hedgehog animated series and Sonic Underground, and adapted for the first eleven issues of the Sonic the Hedgehog comic series.
 * Sonic Underground was the last time that Sonic was voiced by Jaleel White. White would return 14 years later to voice Sonic again in a fan film.
 * According to Tails, Sonic has a beautiful singing voice.
 * It has been said that Sonic cannot cook.
 * Sonic's favorite movie is Space Pigeon 2.
 * In the Sonic Boom series, Sonic has confirmed that he (as of yet) does not have a Super State.[69]
 * In the Sonic Boom series, Sonic is currently the only member of his team to not have his name appear in the title of an episode.
