Sonic the Hedgehog (Sonic Boom)

"Super-fast with a passion for adventure."

- Sonic Boom Official Website

Sonic the Hedgehog is the main protagonist of the Sonic Boom series. He is an anthropomorphic hedgehog gifted with super speed, who fights Dr. Eggman and other forces of evil alongside his group of friends as the leader of Team Sonic to preserve peace and freedom.

Concept and creation
During the development for Sonic's redesign, the developers went through a long process where they experimented with different accessories before they decided to stick with the "Scarf Sonic" design. They settle with giving Sonic a neckerchief because it played homage to the classic adventure theme and was an action adventure trope which fit with Sonic's game character role while emphasizing his "get-up and get-go" attitude and his love for adventure. According to Bob Rafei, Sonic's scarf is partially based on Nathan Drake's scarf from Uncharted.

The sports tape Sonic wears is inspired by fighters and American football players and is meant to give him a sense of practical heroism by showing that that he is not vain, which is a trait more fitting for villains, when saving the world and to give him a more grounded approach. He especially got sports tape around his feet to emphasize that his specialty was speed. While his following design was nearly identical to his main series counterpart, he eventually received blue arms and additional spikes to differentiate the two of them.

Appearance
Sonic retains most of the appearance from his main series counterpart, 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 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.

Sonic Boom: Rise of Lyric
In Sonic Boom: Rise of Lyric, 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 was attacked by Lyric's robots and buried under rubble, but recovered and the group went to Lyric's Lair to stop him. 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.

Sonic Boom: Shattered Crystal
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.

TV series
As Sonic chased Dr. Eggman, he was ambushed by Burnbot. In the ensuring battle, Tails came to Sonic's aid in the Tornado until Burnbot made Tails crash. Finishing Burnbot, Sonic found Tails alive, but hurt. Swearing not to let Tails get hurt again, Sonic fired him as his sidekick once he recovered, and held try-outs to get a new one. During the try-outs, both Tails and Eggman applied, whom Sonic begrudgingly allowed to move on (along with Fastidious Beaver) since he promised everyone could come. As Sonic set up a race to test them, he saw Eggman make Tails crash into a frozen lake with Burnbot. Coming to Tails' aid, Sonic nearly drowned thanks to Burnbot, but was saved by Tails who helped him beat Burnbot. Afterwards, Sonic reconciled with Tails and rehired him.

While at Tails' House, Sonic met Eggman, Orbot and Cubot, whom he reluctantly allowed to stay while their lair underwent repairs. Increasingly annoyed by Eggman, Sonic and Tails almost kicked him out until Amy made them give him another chance. After the duo was kept up all night by Eggman, the doctor told all of Team Sonic that he lied about his lair so he could exhaust Sonic and Tails, and summoned Obliterator Bot to kill them. However, Obliterator Bot misheard Eggman and attacked his lair instead. Convinced by Eggman to stop it, Sonic, Tails and Eggman reached Obliterator Bot's kill switches in the lair despite their downiness while the rest distracted it. Though they could not save the lair, Sonic had Eggman stay at its ruins when he tried to bunk with him.

As Sonic, Amy, Knuckles and Sticks chilled on the beach, Tails showed them his universal translator UT. However, UT created tension between Sonic and the team by translating their private thoughts from the subtext of their speech. When Tails and UT returned the next day, UT "translated" their comments into insults. As they started to fight though, Tails discovered this UT was a fake send by Eggman to tear them apart. While Tails went to save the real UT, Sonic and the other stayed home, not thinking UT was worth it. Later, UT returned to give them a message from Tails and translated it into a call to rescue him from Eggman. At the lair, Sonic and the team freed Tails and beat Eggman's Mega. As Sonic saw more times with UT though, Sticks threw it into the sea.

When Sonic saved the Village from Anti-fire Bot, he and his team noticed Sticks' ill treatment of animals and convinced her to get a pet to learn compassion. Coming with Sticks to look for a pet, Sonic saw her chose a disgusting robo-dog she named "Buster". Over the next week, Buster was an annoyance to Sonic and the team which culminated in Buster keeping them from stopping a robbery made by Orbot and Cubot. As they tried to make Sticks give up Buster, Eggman came with a gift and revealed he made Buster. The gift turned Buster into a larger robot who caught Sonic and the team, but Sticks assumed control over Buster and had him release the team and remove Eggman. The team then said goodbye to Buster as Sticks released him due to his dangerous nature.

While Team Sonic was in the Village as it was hit by meteors, Sticks saved them with her defense system. Later, Sonic and his crew heard from Sticks that she had been nominated for an Awardy Award, but refused to go to its associated gala in fear of embarrassing herself. Begrudgingly, Sonic was made Sticks' escort and helped with her lady lessons. At the gala, Sonic learned Eggman was also a nominee (by cheating). When Eggman did not get the award and attacked everyone in vengeance, Sonic tried to fight his Badniks, but got incapacitated. Thanks to Sticks though, Sonic was freed and he drove Eggman and his Stuffer Bot into retreat, allowing the gala to resume.

When preparing Amy's decorative lunch, Sonic slacked off instead of helping, making Amy feel unappreciated. When Eggman showed up to hire Amy for a redecoration of his lair for Modern Lair Magazine Amy accepted it, much to Sonic's shock. Seeing they did not treat Amy right, Sonic took his team to Eggman's lair to check on her, where Eggman claimed that Amy had chosen to stay. Not buying it, Team Sonic broke into the lair and found Amy encaged. After Sonic made amends with Amy, the team trashed Eggman's lair and his Badniks on their way out, costing Eggman his spot in Modern Lair Magazine. To cheer Amy up, Sonic let her redecorate his shack.

On a trip to Meh Burger with Amy, Sonic's meal was postponed due to Eggman and the employee, Dave. Later, as Sonic and Tails tested Tails' Reverse Polarizer, Orbot came to have Cubot repaired. Soon after, Sonic and Tails went to Eggman's lair after detecting two doomsday devices and discovered that Eggman and his intern Dave were competing to see who could destroy the world best with their doomsday devices. As such, Sonic and Tails tried tricking them into calibrating their devices so they canceled each other out. When they created a black hole instead, Sonic carried out Tails' plan to destroy it with the Reverse Polarizer and saved existence.

While home, Sonic found a batch of Evil Cookies, but had to go help Tails stop his vacuum-robot before he could eat one. When he returned with Tails, only one cookie was left, which he gave to Tails upon his request. Later, Orbot informed Sonic that his team had been turned into Eggman's clones by eating the cookies (which were made by Eggman). As Sonic went to Eggman's lair to rescue his team, he got corned when Eggman had them attack him. However, as his team began to fighting over the honor for capturing him, Sonic made an Evil Cookie with his DNA which he gave Eggman, turning him into his ally. With Eggman help, Sonic made new Evil Cookies which he used to cure his friends. The good Eggman thought they would now work together, but Team Sonic did not like the idea and cured the doctor too.

During a race, Sonic and Tails saved Gogoba Village from the Weasel Bandits when they plundered it. As the Gogobas made them stay for a victory feast at their own expense, Sonic and Tails felt terrible and tried to leave many times, but the Gogobas kept guilt tripping them to stay until they had them remain as their protectors. When the duo failed to get away by giving the Gogobas a security system, Sonic had the successful idea of guilt tripping the Chief into letting them go. Back home though, Sonic saw the Gogobas had moved into his shack so he could protect them. No sooner, the duo was attacked by Eggman and his Badniks. After beating the robots, Sonic and Tails convinced Eggman that the Gogobas would be a great asset to him. Guilt tripping the Chief as well, Sonic got rid of the Gogobas as they chose to follow Eggman.

Another time, Sonic and Knuckles beat Eggman when he attacked them with his Badniks. The following day, they met Orbot and Cubot who were looking for Eggman. Hearing Knuckles' exaggeration of their last meeting, Sonic told where Eggman went. When Sonic played coconut hurl with Knuckles, Eggman came by to attack Team Sonic with Cowbot, a robot that would create a large explosion when destroyed. Sonic therefore distracted it while Tails reprogrammed it, causing it to head for Eggman to kill him. Pressured by his team, Sonic went to warn Eggman with Tails. However, Eggman convinced them to help upgrade his lair's defenses for Cowbot. While waiting for Cowbot, Sonic, Tails and Eggman bonded while roasting marshmallows. When Cowbot arrived, the weapons got gunked up with marshmallows, so they stopping Cowbot by gunking it up too instead. As Eggman then revealed he had planned to make them upgrade his systems for his own usage, Sonic foiled his plan by gunking up the systems as well.

During a battle with Eggman's Octopus Bot, Team Sonic were nearly crushed by a rock slide triggered by Tails' faulty Unbolterizer. While Sonic stopped Octopus Bot, Tails left the crew until he could fix his invention, despite Sonic reassuring him. No sooner, they met T.W. Barker and his traveling circus who needed stand-in performers. Team Sonic volunteered for this and put on a good show in the evening. As Barker revealed his plan to keep Team Sonic as his performers though, he imprisoned them, specifically Sonic in the Sphere of Fear. Fortunately, Sonic got a call out to Tails who rescued them. Imprisoning Barker, Sonic departed with his team.

Over the following week, Sonic competed and won against Knuckles many times, the final game being Gopher Ball. Knuckles, blaming his losses on bad luck, thus tried to use it up by causing himself misfortunes, making Sonic worry for his survival. Persuade by his friends, Sonic convinced Knuckles to have a rematch with him, which was ruined by Eggman who began an invasion of the island. Team Sonic tried to stop the doctor, but Knuckles' bad luck and Eggman's current good luck ruined their chances, so Sonic got Knuckles to join Eggman to have their luck streaks neutralize each other. Sonic's plan soon worked and Eggman retreated. When Knuckles rejoined them though, they discovered his bad luck had been passed over to Tails.

While out stargazing, Team Sonic saw a meteor landing nearby. When Eggman came to claim the meteor, he and Sonic raced to it, which swapped their minds as they touched it. Brought to Eggman's lair by Orbot and Cubot who thought he was Eggman, Sonic sought out his team when the robots did not believe who he was. However, his friends did not believe him either, and Eggman (in Sonic's body) had them drive him off. Using Eggman's army, Sonic returned for a rematch with Eggman when Tails came with the meteor to verify Sonic's claims. Though Eggman refused to swap back with the meteor, Sonic made him do so by threatening to cut Eggman's mustache. Following a fight with Scorpion-bot, Team Sonic noticed Eggman sliding into a slump. After not hearing from Eggman in a while, Sonic checked on him and saw he had lost his drive to be a villain. Sonic soon grew bored with the peace and ended up annoying his team with his restlessness. Sonic was later lured to Eggman's lair by his team so he and Eggman would fight again. Though Sonic saw through this, he re-motivated Eggman his own way and their conflict began anew.

Having helped Tails built a berry picking machine, Sonic joined his team at the pie festival, excluding Tails who was forced to replant the orchard his machine destroyed. When they returned, Tails had left to join the Lightning Bolt Society and the seeds that had been planted turned into mutant flora, so Sonic and Amy left to get Tails back. When they broke into the lodge however, Eggman arrived, who thought they were joining the Lightning Bolts. With the Lightning Bolts failing to stop them and only hindering Eggman, Sonic and Amy got Tails back to help them destroy the mutant plants with his berry picking machine. After Sonic beaten Eggman in his Moth Bot, he was sued by Eggman when the doctor claimed Sonic had broken his neck. At the trial, Sonic stood to lose due to Eggman's machinations, T.W. Barker serving as Eggman's lawyer, and Knuckles' incompetence as his lawyer. Thanks to Amy's inference though, Eggman was revealed to be uninjured and Sonic could again fight him.

When pulling Tails away from his plane, Team Sonic found Eggman selling tomato sauce. Sonic thought the sauce was poisoned, but found it harmless when he was goaded into drinking it, and left Eggman alone. Weeks later, while dealing with faulty electronics, Team Sonic saw Eggman reveal on TV that his dispersed sauce cans had turned their electronics into robots to conquer the island. Fighting off a small army, Sonic and the others went to confront Eggman while Tails got his weaponized plane under control, but were overrun by Eggman's robots. Fortunately, Tails dropped in and shut the robots down with Eggman's controller while Eggman accidentally foiled his plan by revealing it on TV.

While Sonic saw Tails showcase his voice-controlled Tailsmobile, Sonic noticed he had begun making a horrible sound when running, which would have made the Tailsmobile drive Tails into lava had Sonic not stopped it. Unable to determine the cause, Sonic was told not to run. However, he quickly got bored and later felt unneeded when his team kept him from fighting invading Crab Bots. Meeting Eggman, who sympathized with him since he did not deploy the Crab Bots, Sonic confided in the doctor who gave him new shoes which seemingly muted his noise. Back home though, Team Sonic was attacked by Eggman with Giant Robot which grew stronger the more Sonic ran with his new shoes. Unable to remove his shoes or power down the robot, Sonic overloaded Giant Robot by running instead, before celebrating with a run.

As Team Sonic had a movie night, they were attacked by the Egg Tank. During the battle, Sonic was saved when Amy deflected one of the Egg Tank's weapons. As Eggman countered it though, an freak accident occurred, creating an time loop where the day kept repeating itself, which only Eggman knew. In this period, Sonic got captured by Eggman after he refined his attack, only for the time loop to reset it. Eggman thus sought Sonic's help to fix time. After several repeated attempts, Team Sonic helped break the loop by containing its reaction.

While Sonic was taking Knuckles out para-sailing, they accidentally awoke an unbeatable Granifier Giganticus named Rocky. As Sonic reunited with his team in the Village as Rocky trashed it, they realized Rocky just tried to fall asleep. Discovering they could make Rocky fall asleep to Sticks' lullabies, Team Sonic relocated him when he blocked a road, only for Eggman to try and capture Rocky. While Sonic got Eggman to retreat, the team noticed Rocky had fled with Sticks. Failing to find Sticks, Tails' Disasterometer located her and Sonic helped rescue Sticks. Sonic then lead Rocky to Eggman's lair where Team Sonic had him fall asleep to a recording of Sticks’ singing.

As Team Sonic fought Eggman again, Sonic chased him into Buddy Buddy Temple. Falling through a floor, Sonic got injured while Eggman's Eggmobile got damaged. Trapped in the temple and unable to get out on their own, Sonic realized they had to work together and collaborated with Eggman to escape the temple and its death traps. While clearing a trap though, Sonic was left to be crushed by Eggman. However, he was then saved by Eggman who needed help to get out. As temple began to cave in, Sonic and Eggman found a way out as their allies arrived and got everyone to safety. Agreeing to stay as enemies despite their good teamwork, Sonic and Eggman parted ways.

When Team Sonic was at Meh Burger, they met Orbot and Cubot who had deflected from Eggman to be their friends, something Sonic did not take a liking to. Soon after, Eggman, Orbot and Cubot came to Team Sonic for help after a computer virus named Nominatus had taken over Eggman's tech to destroy all life forms. As Eggman's robots attacked, Sonic helped hold them off until Tails, Eggman, Orbot and Cubot destroyed Nominatus. Their truce over, Sonic promised Eggman a fight later. Following a day full of activities, Sonic was goofing off with Knuckles when Amy told him to return a library book she had lent him within a few minutes. Finding the book, Sonic tried returning it, but got sidetracked by the Old Monkey, Sticks, a trip to Meh Burger, and Eggman who had him bring him a chili dog after Sonic bought the last. Short on time, Sonic was attacked by Eggman, who was displeased with his former aid, and his robots, until his team saved him. Then, with some help from his team and Eggman, Sonic returned the book in time in spite of the library closing early.

Meeting with Amy, Sonic heard she planned to go to Hidden Meadows. As Sticks offered to teach her the survival skills for the trip, Sonic thought he was better for this task and bet with the girls that he could teach Knuckles better survival skills than Sticks could teach Amy. Agreeing to a race to Hidden Meadows, Sonic and Knuckles neglected their preparations, so when the race began, they quickly fell behind. Stumbling through the jungle, Sonic and Knuckles either rejected or failed to notice the girls' help, before finding them stuck in an abandoned missile silo. With the girls safe there, Sonic and Knuckles used this opportunity to head for the goal, but was beaten when the girls rode a missile to the goal. When Sonic later pranked Knuckles with his team, they noticed a spy drone from Eggman. Giving the drone false info, Team Sonic lured Eggman into a prank that made Eggman desert technology and his lair. As Sonic was bothered by Eggman's attempts to defeat him without tech, the island got randomly attacked by Eggman's robots and missiles. Sonic sought out Eggman, only to hear from Orbot that the Lightning Bolts Society was behind this, having seized Eggman's lair. Failing to get Eggman's aid, Sonic helped his team attack the lair. When Eggman came though, he helped Sonic outsmart the Lightning Bolts over the surveillance and drive them off, and Eggman returned to his lair.

While out playing, Sonic and his team heard from Amy she was opening her own restaurant in response to Meh Burger's bad service. Filling the role of Chez Amy's staff, Sonic and his friends helped Amy, but left as Amy grew obsessed over her rivalry with Dave at Meh Burger. Despite this, Sonic answered Amy's call to arms when Badniks attacked Chez Amy. Despite their efforts, Chez Amy was destroyed, so Team Sonic returned to being customers at Meh Burger after helping rebuild it from an Eggman attack. When at Meh Burger later on, Team Sonic met Swifty the Shrew. While everyone were impressed by the hip shrew, Sonic found him annoying, especially after he foiled his attempt to show him up. Once he saw Swifty with Tails, Sonic had enough and was goaded into accepting Swifty's challenge to a race where the loser would be banished from the Village. Despite his efforts, Sonic lost to Swifty and was promptly banished. However, when it turned out to be a plan orchestrated by Eggman to leave the Village defenseless, Sonic was unbanished and returned to defeat Eggman and his Swifty robots.

Sonic later found his property littered with traps from Sticks, who tried protecting the team from the "curse of the Cross Eyed Moose". To stop this, Team Sonic followed Sticks to a marmoset named Monkey-Boy to remove the curse, who had them to do chores to prove their worthiness, much to Sonic's annoyance. When Monkey-Boy was attacked by Eggman however, Sonic made the marmoset promise to remove their curse if they saved him from Eggman. Fulfilling their deal, Monkey-Boy fulfilled his, allowing Team Sonic to head home. When Sonic was made the judge of the upcoming Chili Dog Cook-Off, he helped his team manage the event. As the team noticed that those of them who participated had bought phony peppers, Knuckles left to find a new one. At the cook-off though, Knuckles had disappeared, so Sonic and his team went looking, eventually finding him the next day, having passed out from eating a dream-inducing pepper.

After foiling Eggman Spider Bomb plans, Sonic helped with Sticks' yard sale that Amy had forced upon her, though Sonic disagreed with Amy's intentions. While keeping Eggman from shoplifting, Sonic found Sticks' Burrow overrun by the evil Froglodites which Amy had set free by removing the blockade of their caves in the burrow. As the frogs took Sticks into their caves, Sonic lead the team in there and rescued Sticks using her own junk, and the group resealed the Froglodites. In the aftermath, Sonic got Eggman to pay for his stuff. To his confusion, Sonic later found Knuckles filling in for Mayor Fink. While Sonic dismissed Sticks' concerns, he soon found the Village into chaos from Knuckles approving random bills, so he and his team joined the fellow-minded Eggman to stop him. When Knuckles' approval stamp ran out of ink though, they were betrayed by Eggman who seized the stamp to control the Village, although Sonic wondered why it was an issue as Eggman only wanted his trash picked up. After destroying the stamp, Mayor Fink returned to his job, much to Sonic's relief.

When Sonic and Tails found Obliterator Bot on a rampage and destroyed it, they noticed Eggman was really making a movie. Sensing foul play, Sonic declined Eggman's offer to play himself for his movie. When Amy showed him that Eggman got Dave to play him though, Sonic changed him mind. During the filming however, Sonic walked out when Eggman ejected his and Tails' changes to the scrip. Later, Orbot and Cubot told Sonic the movie was a cover-up to mine metal for new robots (which would make them obsolete), but after Sonic stopped Drill Bot, he saw he had been duped into performing for Eggman's movie. Coming to the movie premiere, Sonic learned the movie was meant to enslave the audience with hypnotism. However, it failed due to an error on Eggman's part and everyone could leave.

When Sonic picked up Knuckles for a fight with Eggman, he accidently upset the villagers when he told Mike the Ox that he could not come to the fight as he was "just a guy." With the Village in an uproar over his behavior, Sonic had to joined Amy's sensitivity seminar. When Sonic let Mike join a fight with Eggman as he apologized though, Mike got injured, earning Sonic more ire from the Village and making him retire at Amy's next seminar. As the Lightning Bolt Society began harassing the Village, Sonic refused to help until a sheep stampede occurred, during which Eggman launched a sneak attack on Sonic. Thanks to Mike warning him of Eggman though, Sonic stopped the stampede and beat both Eggman and the Lightning Bolts. Having regained the Village's respect, Sonic dubbed Mike a hero for his aid. During a barbeque, Team Sonic met another Knuckles and learned it was a version of Knuckles from a Mirror Dimension. Helping the alternate Knuckles to get back home, Sonic's advice to be patient fell on deaf ears when the alternate Knuckles left to get the tech they needed from Eggman. However, when learning their Knuckles was fading and that their dimension was in danger of imploding from hosting two Knuckles, Sonic, Amy and Sticks went to Eggman's lair and got Eggman to release the alternate Knuckles. Back at Tails' Workshop, they sent the alternate Knuckles home with tech donated by Eggman.

Helping Tails when his tools got stolen, Sonic tried accusing Eggman of the theft with Tails, only to find him innocent. While they tried catching the thieves with a trap, Sonic and Tails met Orbot and Cubot who took the duo to the thieves, who turned out to the Cubot prototypes who just needed repairs. As Sonic and Tails helped the rejects, they protected them when Eggman came to destroy them. Driving Eggman off with some help from Cubot, Sonic and Tails took the prototypes to a safer home. When later enjoying some commodities unintentionally provided by Dave the Intern, Sonic heard Dave had imprisoned Eggman and hijacked his forces. After Sonic told of his unconcern for Dave's threats on TV, Dave endangered himself and others when trying to attack Sonic with Octopus Bot. As such, Sonic liberated Eggman and made him reveal Octopus Bot's weakness after many arguments, which he used to stop Dave. On the day of New Year, Team Sonic set up the Village festival while warding off Eggman and his Ball Bots. When Sonic attended the party later, Eggman launched his Slow Motion Machine which slowed everything down, except for Sonic due to his speed. To restore the world, Sonic accepted Eggman's wish for a showdown and beat him in several games (since Eggman's machine halted any weapons). When Sonic heard that Eggman did all this to beat him just once before New Year though, he let the doctor win. As Eggman restored time to gloat, no one believed him as nobody saw him win, though Sonic provided his nemesis with some comfort.

When the Justin Beaver fever hit the Village and turned all the females into crazy Justin fan girls, Sonic decided to investigate Justin's producer. Forming the boy band Dreamboat Express, Sonic had himself, Tails and Knuckles pass off as Justin's opening act to the bouncer Salty and got into the set. There, they heard the producer was using music-based mind control to sell merchandise and planned to expand it at Justin's next concert. Unable to convince Amy and Sticks, Sonic and his band had a sing-off with Justin at his concert to find the frequency to break the mind control with Tails' Measure-o-meter. Forming Dude-itude, Sonic and his crew freed everyone's will with their power rock ballet. Later, Sonic had a wheelbarrow race with Knuckles before fighting Eggman's Decimator Bot with his team to save Leroy the Turtle, when he noticed Tails acting absent. Seeing that Tails had a crush on Zooey, whom he needed help talking to, Sonic advised Tails to play it cool by demonstrating it with Comedy Chimp whom he had hired. However, Sonic's idea did not work. When Eggman attacked again though, Sonic and his crew stayed back on Tails' order and watched proudly as Tails stopped Eggman while winning over Zooey in his own way.

Having convinced Amy to let them look after her house while she was gone, Sonic and Knuckles accidently ruined her couch, so they joined Bro-Down Showdown to win a new one. Unfortunately, Sonic got paired up with Eggman and had to compete against an envious Knuckles. During the show, Obliterator Bot attacked the Village, but Sonic could not fight it without getting disqualified, as Eggman had planned all along. Regardless, Sonic helped Knuckles stop the robot when it was about to kill the echidna. Fortunately, a stray missile from the robot destroyed Amy's couch, removing any evidence of Sonic and Knuckles' mess. During a photoshoot Team Sonic watched, Knuckles became famed as "Trash Can Head Guy." While Sonic enjoyed the benefits of being a celebrity's friend, he worried about Knuckles' growing ego when the echidna became the host of the Comedy Chimp Show. Sonic's fears would be confirmed when Eggman attacked the set, having been sent there by an envious Comedy Chimp. Sonic thus rallied his friends to Knuckles' aid. While protecting Knuckles, the echidna came to help them and renounced his fame in favor of his team, to Sonic's approval.

After a trip to Meh Burger, Sonic, Knuckles and Amy met Perci who had a biking accident. Enamored by Perci, Sonic fought with Knuckles over helping her until they took her to Tails' Workshop to fix her bike. As Sonic tried doing Perci's work, he squabbled with his team over pampering her while the workshop caught on fire. After quenching the fire, Tails arrived, and Sonic gave his personal explanation for the mess before Perci corrected it. As Tails realized his security system caused the fire though, Sonic left, guilt-free.

Meeting at a crime scene at Eggman's, Sonic was accused of stealing Eggman's Particle Accelerator, and soon other things, so Sonic fled to clear his name. Getting a new identity and a job at a warehouse, Sonic located the real thief, although he first had to help make an elixir for his injured coworker Earl. With Knuckles coming to aid him, Sonic faced the real thief, revealed to be Metal Sonic. Despite Metal using Eggman's device against him, Sonic beat his rival and returned the stolen goods. However, Sonic was still nearly arrested until Earl brought the inert Metal Sonic, proving Eggman was behind it. When Sonic saw Tails display his Super Antenna, he inadvertently inspired Knuckles to begin inventing. Later, Sonic came to the Robot Battle Royale after Knuckles got Tails to compete with him. There, Eggman won the tournament by seizing Tails' robot-controlling Hypno-bot in the finals, before using it to take over Tails' inventions. While Sonic fought Eggman's forces, Tails got Hypno-bot back and used it to make Eggman retreat. As Sonic suggested using Hypno-bot as a defense against Eggman though, it was blown up by a stray robot.

During a heatwave, Team Sonic tried to stay cool while fighting super-charged Badniks. When the latter began acting haywire, Team Sonic went to check on Eggman and saw he had captured the Archipelago Homeowners Association to avoid eviction, whom Sonic freed. After Eggman and the association worked things out, Team Sonic left. Sonic and co. later learned Amy was into Fuzzy Puppies and ridiculed her, before resuming their routines and Eggman fights. Noticing Amy's recent absence though, the team spied on Amy and learned she and Eggman were "Fuzzy Puppy buddies". Suspicious of Eggman, Sonic had his team watch them at Puppy Con where they stopped a rockslide seemingly caused by the Lightning Bolts, but then learned it was a distraction Eggman staged while he stole a rare game piece. However, Amy defused the situation without Sonic's aid.

After Team Sonic foiled Eggman's plans again, Sonic agreed to his demands for a fair fight by having the team face him one-on-one. Hearing the others got fooled by Eggman, Sonic snidely faced the doctor himself, only to be caught with gear Eggman had stolen from his team. Fortunately, Sonic's friends came to his rescue, and by working together by switching out when needed to keep their deal, they defeated Eggman. After snarking though, Sonic was left in a cage with Eggman by his team for a while. When Team Sonic beat Eggman for the millionth time, they received the Greatest Role Model of All Time Award. However, the team's horsing around made the mayor hire D.B. Platypus to make them better role models, who got Sonic and his team to follow strict rules that made Sticks leave. As the team later tried to stop Eggman's theft of a trophy though, Platypus prohibited from using violence, leaving them helpless until Sticks returned and got rid of Platypus and the audience. Team Sonic could thus return to beating Eggman in their old way.

While stuck in Amy's House during a storm, Sonic, Tails, Knuckles and Sticks drove Amy nuts with their antics. When Sonic found Amy's secret script for A Rose Without Thorns, the team got mad at Amy for her portrayals of them in it. With Amy mad at them for reading her stuff, the team fell apart as they all began arguing. Though Sonic, Tails, Knuckles and Sticks reconciled after a fight, Amy stayed mad since they had trashed her house, so Sonic had them put up Amy's play for her as an apology. While it worked, Sonic took those at the play to Amy's House as a storm began. Sonic later had a stay-awake challenge with Knuckles which he won when Knuckles sought to make amends to Charlie. As Charlie became a villain and started to bully Knuckles with an Ancient weapon, Sonic and his team convinced Knuckles to fight back when he refused to do Charlie more harm. After he beat Charlie, the team joined Knuckles for a snack.

When Team Sonic helped Amy built a bookcase, they got attacked by Team Eggman, Eggman's league of villains. As Team Sonic got separated by Team Eggman, Sonic was left to fight Eggman, Giant Robot and Charlie. Fighting smarter, Sonic was on the verge of winning when Shadow the Hedgehog intervened. Although Sonic was nearly destroyed by Shadow, he managed to beat him when Eggman distracted him. As Shadow left to fight another day, Sonic reunited with his team to juggle with Eggman as payback.

The Big Boom
On the beach, Sonic had a fight with Dr. Eggman in his Big Boy until Tails, Knuckles and Amy arrived and helped bring the robot down, forcing Eggman to retreat. No sooner, Sticks arrived and told them Tails' house had been robbed. Sticks took Sonic and the gang to Tails' house, and they discovered that the whole house was gone: what Sticks meant was that Tails' house had been stolen, and she explains that a "cyborg rock golem" rose up from the ground and left with it. Suspecting it was one of Eggman's creations, Sonic tried making a plan when Sticks seemingly caught the scent of the robot. Though it turned out Sticks was only smelling the grass, the group still found the Rock-cyborg by following its footprints and Sonic got his friends to set up an ambush while he lead the robot to them. The others made the robot fall over, allowing Sonic to destroy it and make Tails' house fall on its original foundation.

Not long after, Eggman returned in the Big Boy and Sonic, Tails, Amy and Sticks engaged the doctor. Amidst the fight, Sonic was knocked away and trapped in a small cage by Knuckles who claimed he was now working with Eggman because he was through with Amy criticizing him. Sonic's whole team was soon captured and taken into the Big Boy's cargo hold. While Sonic went stir crazy, Knuckles revealed he pretended to work for Eggman to fool him before going after the doctor to free them. Sonic was soon after freed by Sticks and in a rush over freedom, he broke the team of the Big Boy as Knuckles made Eggman retreat. After they had dealt with the stray Orbot and Cubot however, Sonic found Amy in a panic over having lost her piko hammer. Back at Amy's House, Sonic, Tails and Knuckles failed to calm Amy down, so Sticks sent them out to find the piko hammer. After looking everywhere on the island without luck, Sonic and Tails returned to Amy when the piko hammer suddenly fell into Sonic's hand. Sonic received Amy's heartfelt thanks and he returned home for the night.

For a climatic battle with the Big Boy, Team Sonic agreed to battle Eggman, only for Sonic, Tails, Knuckles and Amy to forget about it. Later, Eggman, Orbot and Cubot tracked them down in the Big Boy, where Sonic admitted their slip up, and Team Sonic fought Eggman, but found themselves at a disadvantage against the upgraded Big Boy. Coming to their aid was Sticks, who claimed she had found an all-powerful weapon: the Rock of Justice. Exasperated, Sonic did not believe a rock could help them and continued the fight. However, Sticks saved them with the Rock of Justice by throwing it at the Big Boy, causing it to ricochet into the mech and destroy it. After scaring off Eggman and his lackeys, Sonic congratulated Sticks and the Rock of Justice, only to hear that the weapon's power had been used up, and Sonic fell a tear at their loss.

Boom Shaka-laka and Worlds Unite
In the Village Center, Sonic kept an eye on Dr. Eggman as he failed to sell a bridge and later gain the villagers' trust. As Sonic mocked him, Eggman called in his minions which Sonic and his team quickly beat, though Eggman got away. Later at Meh Burger, Team Sonic met Eggman again who asked for aid to operate his rides at the Eggtoberfest, which Eggman hoped to gain the villagers' trust with. Sonic complied, if only to keep an eye on Eggman. Not long after, the villagers were attacked by Eggman's army which Sonic and his team destroyed, earning them the villagers' hailing.

As Sonic was attacked by Eggman's Courier Robot, his team came to his defense. The Courier Robot subsequently became a video phone which Eggman contacted them with, and Eggman challenged them to a fair go-kart race in the Go-kart Pan-island Grand Prix. After a little persuasion, Sonic accepted the challenge on the team's behalf, but he was unable to convince Sticks to join, who was sure it was a trap. On the day of the Grand Prix, in go-karts provided by Eggman, Sonic and his team took the lead as the race started, but when Sonic neared the home stretch while unaware that he was being scanned, he noticed his friends had left the race. As he then crossed a bridge, Eggman triggered a trap that made Sonic fall into the ravine below. Fortunately, Tails, Knuckles and Amy, who were also victims to Eggman's traps, saved him just in time, but as they prepared to get Eggman, Sonic convinced them to wait for that until he had proven that he could beat the doctor fair and square in his own race.

With some help from Knuckles, Sonic got back on the road in his go-kart and soon took the lead despite Eggman's numerous attempts to stop him with traps, but as he neared the finish line, where Sticks was waiting, Eggman attacked with his Spider-Kart and kept Sonic from completing the race. However, Sonic's friends then arrived in Tails' Plane and kept Eggman occupied, which allowed Sonic to cross the finish line and win the race on his own terms. He then joined his team in trashing the Spider-Kart, thus driving Eggman in retreat. Sonic then expressed his gratitude to his team, unaware of where Sticks had gone during the fight. When Sticks returned, Sonic and team joined her at a campfire and listened to her absurd story about fighting an evil robot alongside an interdimensional army. Needlessly, Sonic humored Sticks by supporting her story with how he always turned gold and flew around.

After weeks of beating Eggman's Mebot models, Sonic was called in by Eggman to stop a rampaging gorilla he had ordered. However, Sonic discovered the gorilla, named Kyle the Gorilla, was actually a good guy and let his stay with him rather than with Eggman. When Kyle's clumsiness proved too much to live with though, Sonic took Tails' advice and tried getting Kyle a job. After several attempts, Sonic got Kyle in on the Comedy Chimp Show where he fit in perfectly in the slapstick segments. Sonic later tried taking a nap, but was disturbed by Kyle who convinced Sonic to let him try a new (cliché) bit on him, unaware that Eggman was watching.

Sonic Dash 2: Sonic Boom
In Sonic Dash 2: Sonic Boom, Sonic is a playable character who is available from the start of the game. In gameplay, his special power is "Dash Ring Magnet" which lets him attract Rings while dashing.

Personality
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 cannot process the aspect of being immobilized which makes him extremely stir crazy, and extended times of peace leaves him bored and restless. 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.

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 calls for it, Sonic will forgo his opinions to help those in need.

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-mate and leader, being quick to ask for help and acknowledge their collective contributions, though he is still kind of snarky.

Powers and abilities
Sonic's most notable skill is his super speed, allowing him to run faster than Mach 1. Though his exact top speed is unknown, he is credited as the world's fastest hedgehog and even the fastest being in his universe; he can effortlessly create a sonic boom, run along the surface of water, walls and ceilings, outspeed lasers, start small fires due to friction on the ground, and create strong enough gusts when taking off to knock over boulders. His speed is so impressive that even the Slow Motion Machine could only make him move normally. As far as stamina goes, Sonic's is seemingly limitless as he claims he never gets tired. In line with his speed, Sonic has significant acrobatic skills and agility, sufficient enough to perform perfect synchronized mid-air movements. He also has extremely quick reflexes, being able to react instantly to dangers and perceive objects in slow-motion, and has enhanced jumping skills, allowing him to jump very high into the air.

Sonic possesses significant physical strength, though not on the same level as Knuckles'. He can kick a robot hard enough to knock it through a rock wall, his spin attack can smash through walls, and he can punch with enough force to cause cracks and release shock waves, though it is debatable whether it is due to his super speed, his strength, or a combination of both. Additionally, Sonic can even run at maximum speed while weighted down by objects larger than him. Sonic is also shown to have incredible durability, surviving several laser blasts from powerful Destruction Troops which was meant to kill him.

Sonic's main offensive maneuver is his "spin attack", where he curls tightly into a concussive ball. In this stance, Sonic can damage, destroy and mow down obstacles or foes when in motion. One of his signature moves is the Spin Dash, a nearly unavoidable move where Sonic spins on the spot before blasting off at full speed which can destroy most foes with a single strike. Sonic has mastered this move to perfection, being able to use it with enough precision to weld metal fences together from friction. While not a strategist like Tails, Sonic has a very quick wit and has often come up with his own plans to take down his enemies. He is also a skilled combatant, and his fighting style relies on his footwork styles along with fast-strike tactics and quick maneuvers.

Weaknesses
Like his main series counterpart, Sonic cannot swim and sinks in water.

Doctor Eggman
Dr. Eggman is Sonic's arch nemesis and arch rival, though their relationship is rather complex. On one hand, Sonic has a strong dislike of the doctor and fights him on a weekly basis, though he does not really take account of him and teases him with jokes and sarcasm. On the other hand, when not doing battle, Sonic and Eggman act rather passive, allowing them to be nearby without them going at each other's throats. At times, the two have even been known to hang out together, though Sonic normally retains his general dislike of the doctor. When Eggman claimed to be homeless, Sonic even allowed him to stay at Tails' home, though it was more on the grounds of proving himself the better person.

Ironically, Sonic knows a lot about Eggman's character and his preferences due to their frequent encounters, enough to let them get to the finals of Bro-Down Showdown. Because of his constant victories over him, Sonic has a tendency to underestimate Eggman and forget how dangerous he can be. When dealing with a common threat or problem, Sonic and Eggman are willing to put aside their differences and work together, even sometimes showing a sense of good-spirited comradery and well-oiled teamwork, though they both agree that they can never really be friends because of their different standpoints.

For all their opposing ways, Sonic and Eggman are ultimately co-dependent and need each other in their lives. While he does not mind Eggman leaving his life, Sonic finds things too boring for his taste without Eggman to fight, which makes him restless and paranoid. Similarly, without Sonic to challenge him, Eggman has no motivation to be a villain. For better or worse, their never-ending conflict is what drives them and keeps their lives balanced.

Miles "Tails" Prower
Sonic's best friend and most trusted companion is Miles "Tails" Prower. He shares a brotherly relationship with Tails and they are equal partners in Sonic's adventures. They are extremely close and both are willing to sacrifice their life for the other. When taken to the court, Sonic even emphasized that Tails was the one witness among his friends that he could rely on, underlining just how much trust and faith he has in Tails above others. While Sonic appreciates Tails' support and unwavering loyalty however, he does not appreciate Tails patronizing him.

Sonic and Tails are often hanging out or going on adventures together by themselves, unlike most other of Sonic's friends, hinting how close Sonic is to Tails. They rarely show any strife or hostility between each other and have proven themselves a near-perfect duo; both provides strengths to the other's weaknesses (Sonic handles the muscle while Tails handles the smarts) and neither could get far on their missions without the other's aid. In addition, they have proved to well together in combat.

Though he might put Tails in danger with his half-baked plans, Sonic cares very much for his well-being. Once, when he thought that Tails had been killed after a fight, Sonic decided to fire him as his sidekick so that he would not get hurt. Once Tails proved himself though, Sonic regained his faith in him and rehired him on the spot.

Amy Rose
Amy Rose is another one of Sonic's close friends and teammates. While Sonic at times acts confused about hints to Amy's crush on him, it has been hinted that he is aware of it. This does little to hurt their friendship and concentration, like when they searched for a Chaos Crystal together without Sonic struggling, and Sonic is completely comfortable hanging out with her. Due to Amy's tendency to take charge though, Sonic perceives Amy as extremely overbearing and bossy which brings her at odds with his own laid-back attitude. He is also not very fond of Amy's ideas for group activities. While Sonic sometimes acts inconsiderate to Amy, he still appreciates her as a friend and teammate, will try making up with her whenever he has upset her.

Sonic often claims to have no interest in Amy's love life, such as denying Amy being his girlfriend with suppressed anger when she was addressed as such by Dr. Eggman. However, he brushed off his concerns in an embarrassed way when Knuckles teased that Amy was getting ready for a date and said nothing when Dr. Eggman asked about his "deal" with Amy. Most noticeably, the Bro-Down Showdown buzzers called out Sonic for being wrong when he denied Amy being his girlfriend. Also, according to UT, Sonic cares about Amy's well-being.

Knuckles the Echidna
Knuckles the Echidna is another of Sonic's close friends and teammates, though the two of them are opposites and always disagreeing. Sonic in particular likes to tease Knuckles and does not think he is the sharpest tool in the shed, viewing him as a simpleton that always messes up without his supervision.

Sonic and Knuckles share a mutual bond of respect, though it was not always like this. During their mission to stop Lyric, Sonic was often reprimanded by Knuckles for all the mishaps he caused. Over time though, Sonic slowly reconciled with Knuckles and eventually made up with him. Nowadays, Sonic and Knuckles are deep down the truest of friends (though they will never really admit it), referring to each others as "bros." Whereas Sonic is more formal around his other friends, he and Knuckles are much more relaxed and outgoing when together, spending their time hanging out by roughhousing and goofing off with various extreme and often foolish activities. Akin to Tails, Sonic can also be very selfless for Knuckles' sake; even though it meant facing Amy's wrath, Sonic willingly forfeited his chances to avoid it in order to save Knuckles from Obliterator Bot.

Both Sonic and Knuckles have a friendly rivalry going on and they tend to compete with each other in all kinds of activities. Though Sonic normally remains cool about their rivalry since he usually wins, he rejects the idea of losing to Knuckles on purpose.

Sticks the Badger
Sticks the Badger is a member of Sonic's crew and one of his closest friends. The two are alike in the sense that they "go running into danger without a plan, a direction, or a clue," though it usually falls on Sonic to be the more sensible of them. Like his other friends, Sonic is normally unnerved by Sticks' paranoia and stays skeptical about her theories and judgement in general. He also hesitated to tell her that Lyric had kidnapped Amy because he feared upsetting her. Nonetheless, Sonic accepts that part of Sticks and will apologize for doubting her when he is proven wrong. Likewise, Sonic thinks she is a very nice person deep down.

Very loyal towards Sticks, Sonic likes her penchant for tackling foes head-on and considers her a valued teammate. In spite of his personal dislikes, he will also agree to help Sticks with her tasks at hand, like being her escort to a gala and going pet shopping with her. Once though, he considered himself a better survival expert than Sticks, until he lost a bet to her.

Lightning Bolt Society
Despite being enemies, Sonic does not think highly about the Lightning Bolt Society. Like most others, he thinks they are a bunch of losers and hardly considers them a threat. Among this group, Sonic's most persistent foe is Dave the Intern who often tries to destroy him (when not serving him at Meh Burger), though Sonic hardly spares him a thought and finds him as rather harmless. Nevertheless, Sonic will stop the Lightning Bolt Society whenever they stir up too much trouble.

Shadow the Hedgehog
Shadow the Hedgehog is Sonic's arch rival, who can match him in both speed, abilities and dashing looks. Outside physical similarities though, Shadow is the antithesis to all that Sonic is. Whereas Sonic is joyful, free-spirited and adventurous, Shadow is a brooding, serious and violently aggressive individual. While Sonic relies on his team and believes in teamwork, Shadow is a loner who only relies on himself.

Sonic and Shadow share a bitter arch-rivalry which goes way back. Between the two of them, Sonic is much more lucid about their rivalry, with Sonic approaching Shadow in his usual casual manner or being willing to walk away from him, whereas Shadow is quick to pick a fight. However, Sonic is easily angered by the way Shadow criticizes him for being weak, and they usually end up arguing when they strike a conversation. While deeming Shadow a "hard case", Sonic nonetheless believes he would be a great addition to Team Sonic, displaying great respect for Shadow's skills.

Lyric the Last Ancient
In Sonic Boom: Rise of Lyric, Sonic had a deep relationship with Lyric the Last Ancient, having been the one who trapped him and stopped his plans a millennia ago via time-travel. Sonic himself described Lyric as a "slithering psycho." When first meeting Lyric after accidentally freeing him, Sonic was confused over Lyric's knowledge of him and his grudge at him (as Sonic had yet to stop him in the past). As he learned of his story with Lyric, Sonic became surprisingly determined to stop his plans to destroy the world, which he had resumed, to the point where he would bear the responsibility alone. In the end though, Sonic saw he could not defeat Lyric alone and brought his team in. Debunking Lyric's taunts of how his friends were his weakness in their final fight, Sonic beat Lyric with some aid and saved the world.

In Sonic Boom: Shattered Crystal, Sonic had a less prominent, but still antagonistic relationship with Lyric. After Lyric kidnapped Amy, Sonic made it his personal mission to defeat Lyric and save Amy. Upon meeting him, Sonic was acknowledged as a worthy foe by Lyric, whom Sonic taunted with how he was unstoppable with a team behind him. In response, Lyric trapped Sonic's team. Defeating Lyric and saving his team, Sonic ensured his end as Shadow engaged him.
