Sonic the Hedgehog (Archie)


 * For the version of this character before the Super Genesis Wave, see Sonic the Hedgehog (Pre-Super Genesis Wave).

Sonic the Hedgehog is the main protagonist of the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. He is a mobian hedgehog endowed with the power of super speed and the ability to control the Chaos Emeralds. Regarded as the hero of his world, Sonic has since early childhood stood as the primary opposition to the villainous reign of the evil Dr. Eggman and the Eggman Empire. He is the strongest and the primary agent of the New Freedom Fighters, a generation of heroes whom he inspired with his unyielding heroism and continues to be their source of strength to this day.

Sonic's speed is his ultimate weapon and he has used it to help those in need, as well as foil his enemies' plans. Although he is sometimes overconfident and assumes he can deal with things on his own, Sonic also realizes he has friends to back him up when needed. Additionally, he is willing to put his life on the line for his loved ones.

Appearance
Sonic is a hedgehog with blue fur that covers most of his body, peach skin that covers his arms, muzzle and torso, and emerald green eyes. He has six head quills dropping back from the back of his head, two quills protruding from his back drooping downward and a short tail that points up. He wears two light-weight, hyper friction resistant red sneakers with a white strap, cuffs and a gold buckle, and a pair of white gloves with sock-like cuffs.

The series has offered differing depictions of how Sonic appeared in his younger years. Some sources shown that he was merely a lot shorter, whereas others have shown the young Sonic to have other physical differences, such as his fur being a lighter shade of blue and that his green eyes were previously black.

Early life
Not much is known about the speedy hero's early life, but when Dr. Robotnik began his attempts at world domination as Dr. Eggman, he would quickly make his presence known to the rotund dictator, constantly thwarting his plans at every turn. When Dr. Eggman and his assistant, Dr. Julian Snively, began their strip-mining and processing of South Island as well as major construction and refinements on Westside Island, Sonic made his first appearance to the two doctors on South Island and followed them all the way to their base on the island, battling the duo within the Final Zone.

The two doctors fled to Westside Island where they continued with their original plans, and Sonic would chase them down; however, his victory over the villains inspired the creation of the New Freedom Fighters, who resided in Westside Island's Knothole, a hideaway from Dr. Eggman, who conquered their original home, Mobotropolis. With new friends in tow, Sonic and the Freedom Fighters chased down the two doctors, with Miles "Tails" Prower close to Sonic's side as his sidekick and best buddy. While on Westside Island, Sonic, Tails and Sally Acorn met Dulcy the Dragon who ran away from her home. Tails was slightly frightened by her but Sonic assured him that there was nothing to fear. Dulcy was in disbelief at how Sonic had nobody to tell him what to do and all he had achieved from that. Soon after, he and the other Freedom Fighters taught Dulcy to be herself and to choose her own fate.

Eventually, Sonic would reach the original version of Eggman's flying fortress, the Death Egg, where he battled a Silver Sonic model and Eggman in his battlesuit. Ultimately, Sonic put a stop to the doctors' plans and defeated them.

After these early victories, peace returned to South Island, until Sonic's friend, Tails, was kidnapped by Dr. Eggman. In the Underground Zone, Sonic fought against Coconuts of the Super Special Sonic Search &amp; Smash Squad and the first generation super-Badnik, Egg Antlion. After defeating them, Sonic came across the other two members of the S6 Squad, Scratch and Grounder, who pretended to use their double agent, Breezie, as a hostage, but Sonic managed to take both out. Sonic took Breezie along with him afterwards, who winded up betraying him, with Breezie revealing her betrayal to Sonic when they reached the Scrambled Egg Zone. It was here where the prototype version of Silver Sonic made its appearance and battled Sonic, but was eventually defeated. Sonic eventually faced off against Eggman in the Egg Storm Chamber, where Eggman held Tails captive. However, the Naugus twins, Walter and Wendy, arrived nearby seeking revenge on both Eggman and Sonic. Eggman let Tails go free in an attempt to keep Sonic from chasing after him while Eggman fled before the twins could find him. However, he was intercepted and trapped in crystal by the twins before he could escape, and Sonic caught up with him moments later, only to be trapped in crystal himself by Wendy, and taken away by the Naugus Twins. In the end, the twins were defeated, and both Sonic and Eggman were set free. Sonic however became reluctant to share the tale of Breezie's betrayal even with his closest friends.

When Dr. Eggman conquered Little Planet after it appeared over Never Lake, Sonic went on a new adventure to stop him and save the small planet. On Little Planet there existed the Time Stones, which were powerful gems capable of controlling the passage of time. Eggman had his eye on these stones all along, ever since the planet appeared on the last month of the year, and so he successfully chained Little Planet down on a mountain with his face carved into the mountain set about converting the world into a giant fortress. Sonic arrived on the scene to stop Eggman from taking all the Time Stones that would allow him to manipulate time and conquer the world. It was during this adventure that Sonic met Amy Rose, who had a massive crush on Sonic. Soon after meeting, Metal Sonic swooped in and kidnapped her. Sonic eventually caught up to Metal Sonic, and the two raced against each other in Stardust Speedway Zone, with Dr. Eggman flying closely behind to attack whoever was too slow. After Sonic outraced his metallic doppelganger, Metal Sonic got struck by Dr. Eggman's laser, leaving him out of the picture for the time being as Sonic was able to rescue Amy. Eventually, Sonic successfully prevented Dr. Eggman from obtaining any Time Stones and defeated the evil doctor. Sonic and Amy landed back on their world as Little Planet orbited away in freedom.

Eggman would not stay down easily, and eventually set out to relaunch the Death Egg from where it had crash-landed on Angel Island. He would be joined in this endeavor by Knuckles the Echidna, Guardian of the island and its source of flight, the Master Emerald. Knuckles was convinced that Sonic and Tails were trying to steal the Emerald, and he attacked Sonic and stole the Chaos Emeralds from him after the pair arrived on the island. The pair would go on to engage Eggman's forces and Knuckles in battle on several occasions, though Knuckles would eventually learn Eggman's true nature and the first Death Egg would be brought down for good.

Sonic's battles with the mad doctor would continue, and he later went up against Eggman and the revived Metal Sonic who the doctor rescued from Little Planet. Sonic defeated the two in the doctor's revived Death Egg, the Death Egg Mk. II, which was built around the small planet.

Sonic would have to face off against Dr. Robotnik again along with Tails, Knuckles and Amy on the eastwatch islands in order to stop the doctor from using his new super weapon the Mega Drive by collecting the mysterious Ancient Gears.

At some point in the past, Lupe the Wolf's village was invaded by Dr. Eggman's forces. Thankfully, Sonic, Sally Acorn and Antoine D'Coolette came to her aid. Sonic ran off to follow and defeat Dr. Eggman while Antoine defended Sally and Lupe. Using the terrain of the Thunder Plains Zone to his advantage, Sonic lead the evil dictator into a lightning bolt, destroying the doctor's vehicle and sending him fleeing while Sonic made a mockery of his nemesis's name.

While returning home through Station Square after being gone for a while on a long journey, Sonic encountered the water-based Demi-God Chaos for the first time. Sonic defeated Chaos, but it escaped. The next day, Sonic saw Tails crash in his plane nearby and came to his aid. The fox took Sonic to see a plane he was working on, powered by a Chaos Emerald, but at the workshop Dr. Eggman appeared to take the Emerald. Though the duo beat Eggman, Eggman snatched the Chaos Emerald and revealed Chaos, whom he transformed into Chaos 1 with the Emerald and told his plan to make it invincible with all seven Chaos Emeralds and build Robotnikland upon Station Square. As Eggman fled, Sonic set out with Tails to get the Chaos Emeralds before Dr. Eggman. Sonic and Tails soon got two Emeralds, only for Eggman to briefly knock them out with sleeping gas and steal one. Unshaken, Sonic and Tails soon found another Chaos Emerald, but were attacked by Knuckles, who had been tricked by Eggman into believing that Sonic had at least one Emerald Shard. Sonic fought Knuckles until he dropped the Chaos Emeralds, which were then taken by Eggman and given to Chaos 2, transforming it into Chaos 4. After Sonic and the others beat it, Eggman escaped to his Egg Carrier. Sonic and Tails tried following him in the Tornado, but were shot down.

Back on the ground, Sonic began looking for Tails, but met Amy who wanted him to protect a Flicky. Despite Sonic refusing, Amy followed him until they were attacked by ZERO, who soon kidnapped Amy. Sonic followed them as ZERO fled to the Egg Carrier until he reached a dead end, but then met Tails in the Tornado 2 who got them aboard the Egg Carrier. When they found Amy with Eggman however, Sonic was attacked by E-102 Gamma, but before Sonic could destroy Gamma, Amy convinced him to let the robot go. As the Egg Carrier began to crash, Sonic had Tails got Amy to safety while he followed Eggman. Eventually, Sonic found Eggman with Chaos 6 just as Big the Cat showed up to save his friend Froggy, who was trapped inside Chaos. After saving Froggy, Sonic defeated Chaos 6, but as Eggman escaped, Knuckles showed up, whom Sonic left Chaos to while he followed Eggman. On the way, Sonic found an ancient temple with a mural depicting a monster on the inside and a mysterious light which took him back in time to see the Altar of the Emeralds in ruins and Tikal trying to stop a catastrophe. Back in the present, Sonic found Eggman and beat him for good before reuniting with Tails again.While trying to rest, Sonic had to head out when Tails reported that Angel Island had fallen. There, they found both Knuckles and Eggman, and learned that Chaos was still alive, had rebelled against Eggman to destroy the world, and possessed six Chaos Emeralds. As they were heading out to get the last Emerald before Chaos, Sonic was drawn into the past again, where he saw the Knuckles Clan's attack on the altar and Tikal sealing herself and Chaos inside the Master Emerald. Back in the present, Sonic and Tails found the Chaos Emerald in the Tornado 2, but lost it to Chaos, who became Perfect Chaos and attacked Station Square. As Perfect Chaos destroyed the Egg Carrier 2, Tikal came to Sonic to explain that Chaos was blinded by wrath. After Perfect Chaos released the drained Chaos Emeralds, Tikal wanted to seal Chaos again, but Sonic said it would not work as Chaos would still be full of rage. Sonic's friends then came with the Chaos Emeralds, claiming that he could still use their positive energy. Transforming into Super Sonic, Sonic defeated Perfect Chaos while neutralizing its anger. As Chaos and Tikal departed, Sonic noticed Eggman making his escape and decided to head off himself for his next adventure.

Another adventure would see Sonic gain a new rival in the form of Shadow the Hedgehog. Sonic had to prove his innocence since Shadow was mistaken for him, and eventually Sonic and his friends made their way to Space Colony ARK, where Sonic and Shadow teamed up to stop the Biolizard. Sonic would later cross paths with Shadow again when Tails, Knuckles, and he joined forces to form Team Sonic. This group would battle Shadow's Team Dark and then join forces with them, Team Chaotix, and Team Rose to battle Neo Metal Sonic and his transformed state, Metal Overlord. Sonic would continue to make new friends on his adventures, such as the powerful robot Emerl, who was later destroyed and rebuilt into Gemerl by Eggman. He would also befriend Cream the Rabbit and Cheese while helping them save Cream's mother Vanilla.

When the Black Arms descended on Sonic's World, Sonic worked with most of his friends and G.U.N.'s forces to repel their invasion of the planet. Eventually, Sonic and his friends met up with Shadow (whom they had encountered during this crisis) on the Black Comet, as Shadow was about to hand the seven Chaos Emeralds he had gathered to Black Doom, the leader of the Black Arms. Sonic and the others told Shadow to stop though. It was then revealed that Black Doom wished to harvest humans as food. Taking the Emeralds, Black Doom used Chaos Control to warp the Black Comet down to Sonic's World. Black Doom then explained that he helped Professor Gerald Robotnik create Shadow from his blood in return for the Chaos Emeralds, which were needed to bring the comet down to the surface. Black Doom then paralyzed Sonic and his allies with a special gas and left them to be devoured by his offspring. However, Shadow broke through the paralysis and chased after Black Doom. Eventually, Sonic saw Shadow kill Black Doom, who had transformed into Devil Doom, as Super Shadow and take the Black Comet back into space where it was destroyed with the Eclipse Cannon, stopping the invasion.

Future adventures saw Sonic team up with the otherworldly princess Blaze the Cat to battle Dr. Eggman Nega, and later meet Marine the Raccoon and help her and Blaze battle Nega's pirates led by Captain Whisker. He would also be caught up in Eggman's schemes to harness the power of a monstrous creature in an aborted timeline that saw him meet Silver the Hedgehog while battling the evil of Solaris. Sonic would go on and face new foes, such as the Babylon Rogues and their leader-yet another speedy rival-Jet the Hawk. He would again face Dr. Nega and meet Silver-a first for both of them due to alterations to time-when the time traveling Hedgehog came back in time to try and stop Nega's plans. Another adventure with Silver saw Sonic and Tails attempting to save the alien Wisp from Eggman's clutches.

Prelude to Worlds Collide
At one point, Sonic had to with a younger version of himself to battle two versions of Eggman and the evil Time Eater. Though the Sonics prevailed with the defeat of the Time Eater, it unknowingly let to Eggman's meeting with Dr. Wily.

A little while later, Sonic returned to Mobotropolis with Tails to find the city under attack by the transformed Tails Doll. The pair were about to combat the monster, when suddenly the world was enveloped by the newest Genesis Wave.

Worlds Collide

 * Note: Due to the Genesis Wave, Sonic's history from this point were changed to be nearly identical to that of his game counterpart's.

Sonic once again found himself running through the Green Hill Zone when he felt a sudden sense of deja vu, similar to what he had felt there previously. He shook off this feeling and focused on the task at hand: finding his missing friends. Earlier on, he'd gone to Tails' workshop where the young fox should've been getting ready to set off on a journey through the Mystic Ruins with him, only to find that his best buddy was nowhere to be seen, his bag of supplies spilled out across the floor. Worried about his friend, Sonic then flew the Tornado to Angel Island to get Knuckles to help him search for the young fox, but instead was surprised to find that the Guardian of the Master Emerald was not at his post. Finally, Sonic headed over to Amy's house, with the intention of asking for her help (noting that she'd be good at finding them as she seems always able to track Sonic down easily), but sure enough, the pink hedgehog had also vanished. Realizing that something bad had happened, he approached the Chaotix for help, asking them to join the search.

Sonic was briefly joined in his search by Silver the Hedgehog, who informs him that he felt a disturbance in space-time that he had traced back to this point. Sonic questions whether Silver had, like him, acted upon a gut feeling that something was wrong, much to Silver's surprise. The two hedgehogs both come to the conclusion that Dr. Eggman is most likely the cause of whatever is wrong, moments before Silver is shot down by a mysterious blue-armored boy wearing a purple scarf in front of Sonic's very eyes. Sonic gave chase after the mystery assailant, remarking that he should've shot him while he had the chance. After a long chase, the armored boy quickly ducked out of sight at the very moment Mega Man was approaching their location, himself chasing Metal Sonic. Mistaking the identical Mega Man with the boy he'd been chasing, Sonic strikes the boy-robot with a spindash as Metal Sonic and the boy disappear from sight. After cheering that he'd knocked the scarf right off of him, Mega Man, in turn mistaking Sonic for the strange blue blur he'd been chasing, proceeded to shoot at Sonic with his Mega Buster Cannon, sparking a fierce brawl between the two.

As their fight continued, Sonic bragged about having taken down hundreds of robots in the past; when the fight appeared to be a stalemate, Sonic decided to use the surroundings to his advantage, running through Green Hill Zone's loops to boost into Mega Man and then bounce around him in the springs before knocking him off his feet, only to be punched back by the Blue Bomber. Suddenly, a Warp Ring portal appeared behind the heroic robot, created by Mega Man's father, Dr. Light; this distracted Mega Man long enough for Sonic to disable his Mega Buster. Mega Man then tricked Sonic into following him through the portal and they (along with Tails Man) arrived back in Mega City. Sonic wondered if he was in a place he knew on his planet, though quickly guessed that such was not the case, as Mega Man called his friends Tango, Eddie, Beat and Rush to his aid.

The two heroes continued their fight, Mega Man repairing his Buster and taking to the air against Sonic with Beat and Rush's aid. Tango's use of a spin dash-esque attack only riled Sonic further. However, as the battle began to endanger civilians, Mega Man again attempted to reason with Sonic, only to be confused as Sonic accused him for Copybot's crimes. As they argued, Tails Man attacked them on Eggman's and Wily's orders. This forced them to put aside their feud to protect nearby civilians and engage the Roboticized Master. Unexpectedly, their combined attacks-Sonic Spin-Dash and Mega Man's charged shot-immobilized the Robian, and Mega Man's weapon copying powers restored Tails to normal. Comparing notes, the two heroes quickly realized the truth: that their respective nemeses Eggman and Dr. Wily had joined forces, and that each had been framed-Sonic by Metal Sonic and Mega Man by Copybot. With that issue settled, Sonic suggested they meet with Mega Man's creator, Dr. Light, and they teleported to Light Labs. Unfortunately, they arrived just in time to see the doctor being kidnapped by Metal Sonic and his new partner, Bass. Quickly resolving that they had to save the doctor and Sonic's other missing friends, the pair and Tails teamed up with Mega Man, Rush, and Mega Man's "brother" Proto Man. With Tails' genius at work, they managed to create a portal that allowed them to enter the doctors' Skull Egg Zone.

Making their way deeper into the strange zone, which combined elements from both their worlds, the heroes soon ran into opposition: Copybot, backed by the Genesis Unit. The group's name struck a chord in Sonic, but he had little time to think on it as the trio of Robot Masters attacked. The heroes split up, with Sonic taking on the monkey-like Buster Rod G, who brought back vague memories of fighting Monkey Khan. Sonic was quick to insult the robot. The fight was quickly ended thanks to Mega Man's new weapon-acquired from Tails Man-and the group's team effort. Mega Man and Proto Man then noted the strangeness of the Copybot and Genesis Unit returning, as intelligent robots from their world were incredibly complex and nearly impossible to rebuild. Moving on, the heroes encountered further strange activity, as well as a new threat: a team of eight Roboticized Masters. After a brief battle, Proto Man left and drew most of the group off, leaving Sonic and the others to deal with Vector Man, Espio Man, and Charmy Man. Remembering their defeat of Tails Man, the remaining heroes resolved upon a strategy: Tails would modify the Mega Buster to emulate Sonic's Spin-Dash, and Sonic would run interference. The tactic worked, and the three detectives were soon restored to normal.

Sonic's group continued their journey, but soon ran into another obstacle: the Roboticized Shadow, known as Shadow Man, and his Robot Master ninja partner, also known as Shadow Man. After some confusion caused by the shared name, the heroes engaged the two villains, and managed to restore Shadow to normal only to have him destroy Shadow Man, who had been frozen by the weapon Mega Man had acquired from Shadow. When offered a chance to join their quest or help find Proto Man, Shadow declined both and disappeared using Chaos Control. The warping of space-time rekindled lost memories for the heroes, making Sonic remember that Eggman had altered reality before, and making him dread the possible effects of a second Genesis Wave. Determined to undo the damage that had been done, the heroes pressed on only to meet Silver Man and Blaze Woman. Sonic and Tails engaged the fire-wielding robot, but fortunately were quickly relieved by a restored Silver and Mega Man. With his two friends deciding to rest and regain their strength for the coming battle, Sonic and the others continued forward to find the remaining Masters. Soon afterwards, they met the pair-Rose Woman and Knuckles Man-who had been ordered to destroy them at all costs, including self-destruction. Fortunately, they were able to return the two to normal, and after ribbing Knuckles and being tackle-hugged by Amy, Sonic laid out their game plan. Tails and Knuckles left to join Proto Man and the Chaotix, Mega Man and Rush departed to collect Silver and Blaze, and Sonic and Amy took off to find Shadow.

With their allies assembled-and joined by Shadow's fellow Team Dark member E-123 Omega-the heroes massed at the Wily Egg, where they were confronted by a massive army of Robot Masters, much to Sonic's delight. Sonic threw himself into the battle and continued to provide assistance to his allies while encouraging an anxious Mega Man about their efforts to rescue his father. He was soon targeted by a squadron of high speed Robot Masters-Slash Man, Charge Man, Metal Man, Turbo Man, and Nitro Man-but found his most entertaining opponent in Quick Man. After tripping up the Robot Master, Sonic helped Mega Man restore Rouge Woman-the newest Roboticized Master-to normal before going on a fighting spree across the battlefield. At Shadow and Proto Man's suggestion, however, Sonic broke off from the fight with Tails, Mega Man, and Rush to board the Wily Egg. Just as they were heading to board the flying fortress, however, they spotted Dr. Light plummeting towards certain death from its underside.

Shadow was able to use Chaos Control to save Dr. Light and teleported him onto the battlefield to help the others. Tails was able to hack into the systems and teleported them into the Wily Egg. Once inside, Sonic and Mega Man bantered about the Wily Egg's interior defenses, which were inspired by features from both Death Egg and a typical Wily Castle. At that moment, they ran into the Mega Man Killers. As the two sides engaged, one Mega Man Killer, Punk, used a spin dash-like move to combat Sonic, much to the hedgehog's annoyance. Eventually, Sonic tricked Punk into crashing into his own teammate, Enker. He and Tails then attacked Ballade, but while Sonic managed to land a hit, Tails was hit at point-blank range by one of Ballade's bombs. With Tails too badly hurt to go on, Sonic and Mega Man had Rush carry him out of the Wily Egg. The blue heroes continued further into the Wily Egg, with Mega Man trying to assure Sonic that Tails would be alright. They soon ran into further resistance in the form of the Chaos Devil, which quickly overwhelmed them. Luckily, Duo arrived and saved them. With Duo keeping the Chaos Devil busy, the blue heroes made the last leg of their trek through the Wily Egg, stopping at a Wily/Eggman-themed boss door. On the other side of said door, the power seemed to go out, making Sonic wonder if they had already won. Just then, however, he and Mega Man were ambushed by Bass, Metal Sonic, and Treble.

Sonic immediately engaged Metal Sonic while Mega Man fought Bass and Treble. Reaching a stalemate with their dark rivals, the blue heroes, realizing they were only being stalled to buy the doctors time, decided to try the old "mix-and-match" strategy of switching opponents. However, this plan almost immediately backfired; Metal Sonic disoriented Mega Man with his speed, while Bass fired too rapidly for Sonic to get in the mid-battle banter he favored. The two then decided to gang up on their rivals one at a time, with Mega Man using all of the abilities he gained from the Roboticized Masters while Sonic kept up the pressure. Bass was the first to go down, followed by Treble, and then Metal Sonic.

Soon after this, Eggman and Wily burst into the room in their powerful new battle mech, the Egg-Wily Machine-X. Fatigued from the fight with their rivals, Sonic and Mega Man were quickly beaten and knocked unconscious. They later awakened to find themselves imprisoned in containment pods within the heart of the Wily Egg, face-to-face with the evil doctors and the gathered Chaos Emeralds. It was then that Eggman and Wily horrified the blue heroes with the truth of their master plan: to unleash a "Super Genesis Wave" to not only completely remake their universes in their image, but also erase their enemies from existence. As Mega Man tried to reason with Wily, Sonic, struggling to free himself from his prison, inquired to Eggman if he was worried about reality breaking due to his and Wily's tampering with Space-Time.

At this point, all seemed hopeless. A turning point came, however, when Knuckles, Proto Man, Dr. Light, and Rush broke into the Wily Egg. There, the red heroes attacked Eggman and Wily while Dr. Light freed Sonic and Mega Man. At Light's suggestion, Mega Man fused with Rush to don the Super Adaptor. Inspired by the word "super" Sonic had Mega Man hoist both of them up to the Genesis Reactor, where the Chaos Emeralds were. Then, as the Super Genesis Wave activated, the blue heroes absorbed the Emeralds' power to become Super Sonic and Super Armor Mega Man.

After preventing the evil doctors from killing Knuckles and Proto Man, Mega Man and Sonic instructed them to evacuate Dr. Light and have Duo fall back. A huge battle ensued between the two sides, ending with Sonic and Mega Man emerging victorious. By then, the Super Genesis Wave was already starting to reshape all reality, so Sonic taught Mega Man how to use Chaos Control to restore their worlds to normal. However, Eggman, unwilling to accept defeat, attacked Sonic while his Chaos Control was still charging. After getting Mega Man to restore Earth 20XX, Sonic turned his attention to restoring his own world, which proved to be easier said than done as he struggled to focus Chaos Control under Eggman's assault. Realizing it was all or nothing now, Sonic used Chaos Control. Due to Eggman's interference, however, it was clear something awful was now about to happen to their world. As Sonic wondered what Eggman had done, white light consumed them both...

Countdown to Chaos

 * Note: From the readers point of view, this picks up from where Sonic's original timeline ended.

Sonic returned after the Super Genesis Wave, but suddenly had a completely different set of memories: including the recollection that they had just been attempting to rescue Mecha Sally at the Northern Tundra with Silver and Team Fighters, seconds before being pulled into an adventure where he teamed up with a hero from another world. Noting the absence of both Amy and Silver, he was looked over by a concerned Tails, who reminded him that they were there to rescue King Acorn. Sonic quickly guessed at Walter Naugus' involvement, and the depowered sorcerer himself fled the city, completely ignoring his enemies. During the course of the battle with Tails Doll, Tails' memories of the unaltered reality returned, and the two swiftly acted to defeat the monster. As they headed for Castle Acorn, Sonic's memories of this new reality came to him, including the circumstances of Dr. Robotnik's initial meeting with King Acorn. Upon freeing their monarch, the pair were surprised to find that he had become healthy and cheerful, which Sonic noted as one positive change to their world. After discussing the matter with Nicole, Sonic and Tails determined that their best course would be to locate the other Freedom Fighters.

Sonic and Tails soon found themselves the Mystic Ruins, searching for Rotor and finding Big the Cat instead. Fortunately, Big knew where their missing friend was located, and led them to the general area, which Sonic recognized as the Final Egg. Realizing that he recognized the area from his memories of the new timeline, Sonic noted that it was becoming harder to distinguish between the two. The heroes' pondering was put on hold as they realized that the Sky Patrol, Rotor's location and the Freedom Fighters' new base, was under attack by Spinners. Sonic and his two companions engaged the enemy alongside Rotor, defeating the lesser robots and a new Silver Sonic who appeared to join them. Afterwards, Sonic and Tails reunited with Rotor, both of them nothing with surprise the Walrus' vitality given his previous injuries and girth in the original timeline. Knowing that it was the only real way to help their friend realize what had taken place, Sonic and Tails handed him Nicole, granted Rotor his own memories of the other reality. Rotor reacted poorly, but managed to inform the pair that Sally and Bunnie were on deep cover missions, Antoine D'Coolette was with Uncle Chuck in Knothole, and Amy had disappeared mysteriously.

Making their way to Knothole in the Wood Zone, Sonic and Tails found Antoine and Chuck, whom they were both happy to see given all the changes to reality and Antoine's previous condition. They were also stunned to encounter a new, and yet familiar face: Ben Muttski, Sonic's Mobini dog of the old reality turned Mobian. At Tails' urging, they refrained from restoring Chuck's memories, choosing instead to restore Antoine's. After telling him what little they could of Bunnie's whereabouts, the pair were suddenly shaken-quite literally-as a powerful tremor rocked the area. A massive fissure appeared, and both Chuck and Muttski fell in. The Freedom Fighters managed to save them, but in the process, Sonic inhaled some Dark Gaia Energy that the pair had extracted from below the surface for study. After displaying a brief, feral reaction, Sonic claimed to be fine, refuting Chuck's insistence that he see a doctor. Antoine reluctantly decided to escort the scientists to Spagonia, entrusting Sonic and Tails with the task of finding Bunnie and restoring her memories.

The pair made their way to the Metropolis Zone, where they found Bunnie disguised as a member of the Egg Army. After being reminded that she was still partially roboticized, they decided to wait until they could reunite with the others before giving her alternate memories. Working together, they helped her complete her mission: acquiring a shield generator for the Sky Patrol from Eggman's Death Egg Mark 3 project. Returning to the Sky Patrol, they found Antoine waiting, and after restoring Bunnie's memories left the distraught Rabbot to be comforted by her husband. Still concerned over Amy's absence, Sonic decided to focus on locating Sally next. The heroes also had to deal with another dilemma: Nicole's diminishing reserves of Genesis Wave energy meant that she might only be able to restore one more set of memories.

A return trip to Mobotropolis found Sonic arriving just in time to save Sally, Amy, Cream, and the Honor Guard from the attacking Metal Sonic. After working with Tails to deal with his metal doppelganger, Sonic happily reunited with his friends, though his comments about the alternate timeline and the Genesis Wave left the pair confused. Following a brief reunion with her father, Sonic took Sally and the girls back to the Sky Patrol, where they prepared to restore Sally and Amy's memories. Like the other Freedom Fighters before them, the two-particularly Sally-were deeply shaken by their newly regained memories. Unfortunately, they would have little time to mull the experience over, as Nicole finally computed the horrific consequences of the Super Genesis Wave's improper reversal. Not only had the entire multiverse imploded, but the damage caused the entire planet to break into large fragments. The Shattered World Crisis had begun.

Act One
The Freedom Fighters quickly traveled to Station Square in order to provide relief to victims of the Shattered World Crisis. Splitting into two teams coordinated by Sally, Cream, and NICOLE from the Sky Patrol, they set out to rescue as many of the civilians as they could. Despite their valiant efforts, the task proved overwhelming, and Sonic began to exhibit further signs of transformation as the stress got to him. Fortunately, Captain Amanda Tower and the Letter of Gabriel arrived with G.U.N. support forces to take over the rescue effort. However, the Freedom Fighters were soon informed of another piece of bad news: Muttski called in from Spagonia University to inform them that Chuck and his colleague Professor Pickle had been abducted by Eggman's forces.

Sonic and the Freedom Fighters managed to locate the captured scientists aboard an Bullet Train heading for the Rail Canyon Zone. Intercepting it in Soleanna Forest Zone, the group split into two teams to board the train and rescue Chuck and Pickle. Sonic's team were tasked with locating the missing captives, and initiated a car-by-car search. However, the other group had the misfortune of alerting E-106 Eta to their presence, and the robot's rampage made the train accelerating uncontrollably. After fighting a number of Badniks, Sonic located his uncle and the professor, only for Eta to arrive in the car ready for a fight. The battle with the super Badnik proved more challenging than Sonic expected, and the stress of the moment caused him to exhibit further signs of transformation. Fortunately, Amy arrived just in time to subdue Eta, and the heroes were able to escape the train with the two scientists. A subsequent debriefing made the Freedom Fighters aware of the existence of Dark Gaia and the effects of its essence, which Sonic-despite his efforts to appear nonchalant-was troubled by given his previous exposure to it. The Freedom Fighters were thus left with a new quest: to locate the missing Gaia Temples and Chaos Emeralds in order to restore the shattered planet.

The search took Sonic, Amy, and Rotor to a seemingly uninhabited coastline, where they heard a mysterious voice coming from underground. Soon enough, Razor the Shark arrived to lead them to the Eusebes Shrine, where they were introduced to the voice's owner: Coral the Betta. The trio spent some time exploring the shrine and its adjacent Chao Garden, and getting to know Razor, Coral, and Coral's apprentice Pearly the Manta Ray better. Unfortunately, the pleasant visit was interrupted by the arrival of Captain Striker and the City Guard, who demanded to know what the surface dwellers were doing in the sacred shrine. After a heated discussion, Sonic and Amy volunteered to accompany Coral and the guard in appearing before King Puff and Queen Angelica, rulers of the city of Meropis. Sonic attempted to explain that the recent problems that had befallen the city were caused by Eggman shattering the planet, but the king and queen refused to believe him. They thus stripped Coral of her title, and informed the Freedom Fighters that they were required to leave the city the following day. Sonic and Rotor briefly argued over helping Coral and her friends, but Amy diffused the situation and suggested that they take them aboard the Sky Patrol. Unfortunately, Coral was unable to maintain the city's mystical shield due to the stresses put on her, and it collapsed, allowing city and shrine to be swarmed by Dark Gaia Creatures.

Sonic, his teammates, and Razor managed to fight off the first wave to attack the shrine, and Sonic and Rotor left to aid the city's defenders and see about getting help for the shrine. Sonic grabbed a pair of Air Charms to allow the pair to breathe underwater, and they soon located Captain Striker. Unfortunately, he refused to send any support to the shrine while the city was under attack, and Sonic and Rotor were left to continue fighting in defense of Meropis. They soon ran into the commander of the minions, a Dark Guardian, and began to battle it. Unfortunately, they realized too late that their Air Charms were not fully charged, leaving them on the bottom of the ocean with no air to breathe. Sonic began to transform again, only to be interrupted by the Dark Guardian throwing Rotor into him. Just when the pair seemed doomed, however, an unexpected ally arrived: Chaos. Creating air bubbles around the pair, Chaos attacked the Guardian with the ocean as his weapon. The battle soon ended and Coral restored the shield, and she was subsequently reinstated as priestess. Tikal provided some counsel to help the heroes on their quest, and they set out with a new supply of Power Rings for the Sky Patrol.

On their way to Soumerca in their continuing search for the Chaos Emeralds and Gaia Temples, Sonic and the others were treated to a tour of the Sky Patrol by Rotor, who also handily dispatched the attacking War Walrus Badnik Horde Commander. Sonic, Sally, and Amy were then deployed to recover a Chaos Emerald, only to run into a new enemy-E-113 Xi-and old friends-Mighty and Ray. After comparing notes, the two heroes introduced Sonic's team to their mentor Moss the Sloth, who sensed the darkness that Sonic had been struggling to contain within himself. Once again doing his best to assure his friends that he had things handled, he requested that Amy use her newly learned Mystic Melody to locate the Emerald. Joined by Mighty and Ray, the trio journeyed to the nearby Soumerca Egg Army base, only to be ambushed by Egg Boss Thunderbolt, whose electrical attack proved the final push to complete Sonic's transformation into the savage Sonic the Werehog.

Enraged and feral, Sonic attacked and swiftly defeated the Egg Soldiers, and would have killed Thunderbolt had Mighty not engaged him. Between the Armadillo's efforts and Amy and Sally talking him down, Sonic gained a measure of control over himself. The group then returned to Moss' hut, and the return of daylight saw Sonic returned to his normal self. However, he quickly resolved that he couldn't afford to return to the Sky Patrol until he got his new savage side under control. He thus joined Mighty and Ray under Moss' tutelage, though as usual he initially found himself trying to prove his own superiority. Moss quickly deduced that the root of his problem was his need to be in control, and that mastering his Werehog form would require acceptance of his own uncontrollable nature. After gaining this mastery, Sonic found himself confronted by another attack from Thunderbolt: the Flying Dynamo. However, with his new powers and the aid of Mighty and Ray, he proved triumphant, and soon returned to the Sky Patrol. Finding his teammates beaten and weary after a failed attempt to recover another Chaos Emerald, he rallied their spirits, reminding them of their previous successes. Unfortunately, even Sonic was appalled when Nicole revealed that another Chaos Emerald was in the hands of an old enemy: none other than Breezie.

After sharing the story of Breezie's betrayal-and his reasoning for not doing so beforehand-Sonic learned that he, Amy, and Tails had been accepted into Breezie's Chaos Emerald Championship as competitors, but that the other Freedom Fighters had been denied entry. Rotor proposed stealing the Emerald given the stakes, which Sonic liked the idea of, but Sally and Amy both spoke against it. After learning that Sally had also attempted to buy the Emerald from Breezie, Sonic joked with her about how her father felt about her use of the kingdom's funds in both this attempt and hiring the Chaotix to help find the Emeralds. Sonic and the rest of Team Fighters traveled to Casino Park, where they were greeted by Breezie and had the tournament rules explained. Looking to keep his Werehog form out of the public eye, Sonic insisted that his matches take place during the day, and threatened to walk out when Breezie didn't want to accommodate him. After succeeding in this, Sonic and his friends met Honey the Cat, Amy's favorite fashion designer, who was also entering the tournament. She proved sympathetic to their cause, offering to give them the Chaos Emerald in the event that she won the tournament. In the first round Sonic triumphed over the human fighter Segata Sanshiro, and after briefly basking in the adulation of the crowds was informed by Amy that the sun was about to set. He quickly returned to his room and transformed, and dejectedly settled in to watch the rest of the matches on TV. The first round ended with Tails eliminated from the tournament, and Sonic was paired with Honey for the second round.

Sonic took a breather from laughing at his foes when he noticed Tails pouting over his loss to Honey in the previous round. Tails explained that he was upset that people all over the world got to see him lose like a chump, but Sonic assured him that people everywhere knew him as his best friend and the hero who saved Station Square. Meanwhile after Nack the Weasel was declared the winner, Sonic asked Espio the Chameleon if he was happy to see his loss against Bean the Dynamite avenged. He also asked why he didn't manage to sneak Vector the Crocodile or Charmy Bee into the tourney. Espio explaind that he only planted Knuckles because he was in the area and it shouldn't have worked in the first place, suggesting that Breezie is aware of the sabotage and has tampered with the brackets herself. Espio also reminded Sonic that Dr. Eggman is sure to be involved and not to let his guard down. As they finished their conversation, Amy and Knuckles began their fight. Amy was getting pumped to take down Knuckles and face Sonic in the finals, but started over-analyzing the situation and worrying about disappointing or hurting him. While she was distracted, Knuckles landed an explosive punch which sent her flying into the spectator seats. Sonic and Tails glared at Knuckles. Sonic and Tails later visited Amy in a hospital room, where she was more annoyed about her loss than her injuries. Sonic took her hand and asked if she's okay, but Amy insisted that she was fine and asked Sonic to avenge her loss before swooning over her hero. Tails also requested to be avenged as Sonic headed out to start his match with Honey. Sonic and Honey met in the ring and shook hands, ready to fight, but Honey admitted that Sonic needed to win the Chaos Emerald far more than she needed to promote her brand. Sonic offhandedly mentioned that they still needed to put on a show for the crowd when Honey flipped him over her shoulder and slammed him into the ground. They had a fierce fight, dodging and countering attacks, when Honey decided to use her afterimage dodge. Recognizing the move from her fight with Tails, Sonic grabbed Honey and flinged her out of the ring. As she soared through the air, Honey was overcome by how cool their fight was. After Knuckles won his match against Nack, he and Sonic entered the ring for the championship match. The two heroes teased each other, joking about past fights and getting ready for a real fight.

Upon learning that Knuckles had left Angel Island after being forced to shatter the Master Emerald, Sonic offered to throw the fight so that Knuckles could resume his quest. Knuckles refused and the battle continued, until Metal Sonic broke into Casino Park thanks to the Hooligans' sabotage. Putting aside their fight and teaming up with Sonic's teammates, Espio, and Honey, they managed to recover the Emerald. Knuckles and Chip were then invited to join the Freedom Fighters aboard the Sky Patrol, and agreed to do so. While traveling aboard the Speed Star, however, the pair were treated to an unexpected surprise as Sonic transformed into the Werehog. Shortly thereafter, Sally received a distress call from Gregorios in Apotos. Sonic and the other Freedom Fighters subsequently traveled there in search of him, only for Sonic to run afoul of Dr. Eggman and a patrol of Egg Swats. Their battle was interrupted by the arrival of the Ifrit through a strange phenomena known as the Genesis Portal, but Sonic was able to drive it back through with help from Silver the Hedgehog.

On another trip in Apotos, this time accompanied by Antoine and Chip, Sonic was forced to battle a force of Badniks. He and his companions then found Gregorios, who led them to the hidden Gaia Gate. He explained that they could use it to access the Gaia Temples without finding them through the use of the Gaia Keys, thought Sonic took occasion to mock Antoine's reactions to various bits of information he gave them. Gregorios then provided the trio with a list of names of families who protected the keys, wishing them luck as they departed. Sonic transformed into the Werehog yet again and expressed his hope that he would return to normal once the world was restored, while Chip hoped that his memories would return. They were then forced to deal with a force of Dark Gaia Creatures led by a Dark Gaia Titan, but were joined by Bunnie, Knuckles, and Amy. After defeating the creature and recovering a Master Emerald shard from it, Sonic and his friends passed on their new information to their reinforcements. The revelation of the Gaia Keys opened the way for Amy and Knuckles to leave in search of the Master Emerald shards, and Sonic found himself being teased over his reaction about Amy leaving.

As Sonic attempted to recover the final unclaimed Chaos Emerald from Metal Sonic as he pursued him through the Crystal Desert Zone with Bunnie and Tails, Sonic ended up grabbing a hold of Metal Sonic and being dragged through a Genesis Portal into the Burning Ruin Zone. There he met Silver, and was distracted enough that Metal Sonic was able to punch him in the stomach and escape. After exchanging greetings, Silver revealed that he was still in the process of finding and closing the various Genesis Portals, a large number of which led to Sonic's world in his present. They then set out to stop Metal and find a portal Sonic could return home. They eventually succeeded, trapping Metal Sonic in another dimension while Sonic returned home with the Emerald.

Worlds Unite
The New Freedom Fighters' search for the final Chaos Emerald led Sonic to the planetary fragment on which Green Hill Zone rested, and he wound up running underneath it. Following a reading from Tails, he located another Master Emerald shard, though Sonic bemoaned the fact that they could not detect the Chaos Emeralds more reliably. Unfortunately, Zavok, Zor and Zeena of the Deadly Six-acting under the control of Sigma-attacked him. Though he put up a fierce fight, the weight of numbers and the powers of their armor saw him defeated by the wreckage of numerous Badniks. He was then brought to Sigma's new base on the Lost Hex along with a captured Mega Man, both heroes having been captured on the suggestion of their nemeses Eggman and Dr. Wily, both of whom had been enslaved by Sigma. The two, while unconscious, were then transformed into the latest Roboticized Masters, and Sonic Man was dispatched to Mega City to set up one of Sigma's Unity Engines. The Light Robot Masters appeared to challenge him, but proved no match for the corrupted Sonic.

As a result, Dr. Light was forced to call upon Quake Woman and some "reformed" Wily Robot Masters to try their luck. Unfortunately, they fared no better, and Break Man similarly proved to be no match for Sonic Man. As a result, he was able to complete setup of his Unity Engine, and Sonic's World and Mega Man's World began to merge together. This led to Sonic Man and M'egga Man being brought together, and the activation of another set of programming installed by Eggman and Wily. The two then attacked each other, and eventually returned each other to their original forms. Recognizing his old friend, Sonic helped refresh Mega Man's memories-and those of his allies-regarding their previous alliance since they forgot due to the timeline of their world going back to it's proper position. Joined by X, Mega Man's descendant from the future, Sticks the Badger, a resident of alternate reality not-too removed from his own, and their allies, the heroes then boarded the Sky Patrol to launch their campaign against Sigma.

While in flight, the heroes determined that the effects of their worlds being merged together was causing the Unified World to deteriorate. After being unexpectedly joined by Eggman, Wily, and Xander Payne, they learned that Sigma's plans involved fusing more worlds together and obtaining infinite power by draining their power. The heroes thus set course for the Lost Hex; along the way, Sonic talked to Mega Man about their first meeting. Though he could not remember the events, Mega Man could tell that his blue friend was, to a degree, exaggerating.

Sonic and his fellow heroes then joined together in facing the Deadly Six and Sigma's Mechaniloid army, with Sonic encouraging Mega Man not to take the situation so seriously. Unfortunately, he would subsequently be attacked Mega Man and their other robotic allies, who fell under the technology-manipulating powers of the Zeti. Sonic and his organic teammates were thus forced to engage their friends, but due to their desire not to harm them were forced to retreat inside the Sky Patrol. Fortunately, Eggman and Wily managed to halt the villains and their unfortunate puppets using their Egg-Wily Uppity Robot Scrambler Cannon. The heroes' troubles were from over, however, as Sigma emerged from the Lost Hex in a massive new robotic body, accompanied by an army of Mavericks. Weary from their previous battles, the heroes engaged the Mavericks, but were unable to stop the majority of them from scattering through Genesis Portals to attack other worlds. However, they were saved when Sticks returned from a trip to the World of Street Fighter with some of that world's heroes, though Guile's Sonic Boom maneuver did not impress Sonic. Given the chance to recover, the heroes prepared to follow Sigma's forces.

Sonic joined Break Man in traveling to the world of Alex Kidd, where they recruited Alex Kidd and Stella to their cause. They later rejoined their allies only to find the Sky Patrol destroyed, but joined the assembled force of heroes and villains in launching a massive attack on Sigma. While they succeeded in defeating his defenders and destroying his giant body, it proved to be a mere protective shell for his ultimate form. Sonic and Mega Man were thus forced to use the Chaos Emeralds to take him on as Super Sonic and Super Armor Mega Man. Even then however, they would have failed had it not been for Eggman and Wily's interference. They managed to destroy Sigma, but his actions had left reality dangerously damaged, and it was only Xander Payne's quick-thinking that saved the universe from annihilation. However, the events of the conflict with Sigma were undone, and Sonic found himself in touch with a very much alive Shadow. The battle was not entirely forgotten by Sonic, as he recalled once again fighting alongside Mega Man.

Act Two
Following his second inter-dimensional adventure, Sonic returned home and resumed his search for the Gaia Keys, though he soon ran afoul of Tundra the Walrus. Following this clash, he was reunited with Lupe the Wolf, and together they set out to take down E-118 Tau. He would then lead Antoine and Big to Shamar, where an effort to rescue the local Gaia Key Guardian Ehsan from the Midesta Egg Army had them team up with the Desert Raiders to rescue Ehsan, earning them two more keys. Sonic, Tails and Chip then made a trip to Mazuri where Sonic distracted the Efrika Egg Army while Tails and Chip took the Gaia Key they had stolen. Sonic later headed for the city of Chun-nan to search for the next key, where he was aided by Dulcy the Dragon. However, after meeting the other Shijin Warriors, Sonic and his crew learned that the Gaia Key's guardian was trapped with the Dark Gaia Phoenix; a powerful phoenix spirit corrupted by Dark Gaia energy. The Freedom Fighters soon came up with a plan and that night Sonic (in his Werehog form) battled the Dark Gaia Phoenix to weaken it enough for Chip to restore it back to normal while they received the last Gaia Key from Zonshen. Back on the Sky Patrol with all the Gaia Keys and Emeralds secured, Sonic and Sally contacted their various allies and announced their plan to stage a worldwide assault on the Eggman Empire as a distraction so they could fix the planet.

Soon after, Sonic was planning their celebratory party before he and the Freedom Fighters fixed the world. They were interrupted by an attack by the Battle Bird Armada and Phage. Sonic fought alongside Bunnie and Antoine topside against the incoming army but did not know that Speedy sneaked inside the Sky Patrol to kidnap Chip. The Sky Patrol's engines were blown up, which caused Sonic to panic and made him ask Bunnie to throw him to the Battle Fortress in a last ditch effort to rescue Chip. However, he was unable to reach him and fell down.

Personality
Sonic is an extremely confident individual who lives for adventure and going as fast as he can. He's a born risk-taker, and not always in favor of following the rules. Be that as it may, he has a firm conviction of justice and a desire to see Dr. Eggman and all others like him stopped. If Sonic has a flaw besides recklessness and a certain disregard for authority, it's that he tends to take too much upon himself, much like his friend Mighty. He also enjoys somewhat antagonistic friendships with both Knuckles and Antoine.

Powers and abilities
Sonic's most notable ability is his incredible super speed, allowing him to cruise at speeds far surpassing Mach 1 which is at the blistering speed of 768 mph or more. While his top speed is unknown, glimpses of Sonic's prowess are shown in his tendency to routinely scale vertical walls, effortlessly knock down enemies in his path and run over water, plow straight through foes, and even cause the ground to explode in his wake. He is also stated to be the fastest thing alive in any world.

Sonic has demonstrated complete mastery of his speed at any level. Not only can he run at maximum tilt in straight lines, but also in full tight circles and through sharp turns with full control over his momentum, and without recklessly crashing into unintended targets. However, he has trouble keeping his balance when coming to a sudden halt at full speed though. As far as stamina goes, Sonic's is seemingly limitless as he is never winded from running. Sonic can also set strong winds in motions with high-speed movements to attack opponents, similar to aerokinesis.

Sonic possesses extreme acrobatic skills, agility, and reflexes enough to compliment his astonishing speed, enabling him to avoid sizable voluminous and minuscule obstacles with precise jumps and delicate movements despite their close proximity and incoming speed.

Sonic is incredibly resilient to pain and damage, capable of taking a series of pummeling from a large spectrum of adversaries without any lasting injuries and continuing the fight. He is also a skilled fighter and a profound user of hand-to-hand combat. Even as a child, he had the capabilities to take on hordes of Eggman's robots. Like Shadow, Sonic can use the power of the Chaos Emeralds to perform Chaos Control, which allows him to teleport to other locations.

Sonic's primary offensive maneuver is the Spin Dash, a technique in which he homes in on the target while curled into a concussive ball or cutting disk which can damage, destroy, mow down, or burrow through many obstacles or foes. He also has an aerial variant of it called the "Homing Attack" where homes into a target from midair while in spinball form.

Super Sonic
By absorbing the seven Chaos Emeralds, Sonic can transform into Super Sonic. While transformed, his natural talents are not only increased exponentially, but he is also granted the ability of flight, invulnerability and can as well manipulate Chaos energy.

Sonic the Werehog
When Sonic accidentally inhaled a concentrated dose of Dark Gaia Energy, he unwillingly gained the ability to transform into Sonic the Werehog, a mutated version of his original form. In this form, Sonic is granted increased strength, elastic arms and sharp claws. However, the corruptive influence of the energy initially caused him to become extremely violent and aggressive. However, he soon learned to exert control over himself in this form. When exposed to sunlight, he automatically reverts back to normal.

Sonic Man
When he was subjugated to Dr. Eggman and Dr. Wily's specialized roboticization procedure, Sonic was turned into the Roboticized Master Sonic Man. In this form, though deprived of his free will, Sonic can overwhelm several Robot Masters at once, and his speed is so greatly enhanced that time-slowing powers have no noticeable effect on him. He can also use a variety of Special Weapons.

Dr. Eggman
Dr. Eggman is Sonic's arch nemesis, due to the latter having constantly foiled his schemes for world domination. Despite Sonic's massive streak of victories, he's occasionally had to team up with the doctor for the greater good, such as when the Space Colony ARK was plummeting towards the planet, or when the super-dimensional tyrant, Sigma, had begun wreaking havoc across multiple worlds, Sonic's included.

All the same, though, while Eggman will stop at nothing to defeat Sonic, and vice versa, Sonic has never really been shown to take much account of his adversary; he takes his fights with Eggman and his goons very lightly, cracking jokes and remaining fully confident that he can ruin his enemy's day, even when being confronted by the madman's deadliest of forces.

Miles "Tails" Prower
Tails is Sonic's best friend and sidekick, helping him a lot on his adventures. Sonic and Tails are as close as brothers and always stick by each other's side, willing to put themselves and/or anything at risk for those they love and care about.

Amy Rose
Amy is another one of Sonic's close friends, and also happens to be his self-proclaimed girlfriend. Amy has been a maniacal fan of Sonic for a long time, but Sonic does not show as much attraction to her. Her affection for Sonic grew after he rescued her from Metal Sonic.

On occasion, Sonic has been known to affectionately tease Amy for her crush on him, though deep down, he does not reciprocate any her of feelings.

Sally Acorn
Sonic is shown to retain a great fondness for Sally in the altered reality, not to mention a notable sense of relief over her no longer being a minion of Eggman's. While their dynamic friendship remains the same, they do not share a romantic bond.

Antoine D'Coolette
Antoine is another one of Sonic's friends (and teammates). Sonic was happy Antoine was recovered and healthy when meeting up with him, and Sonic was said to have helped him gain the courage he needed to protect the kingdom.

Bunnie D'Coolette
Bunnie is also a friend of Sonic's. She was depressed when she was cyborged. However, Sonic and his fellow Freedom Fighters helped her through those times as well as show her that she was still herself, both prompting and inspiring her to fight alongside the rest of her friends, and, of course, use her cybernetics to her advantage.

Rotor the Walrus
Rotor is another intelligent friend of Sonic's, not to mention a brawny one, at that. He and Rotor have worked together in the past under many conditions. While the two each have good hearts, their attitudes towards mission vary considerably, to the point of them arguing, as seen throughout the time spent by them and Amy Eusbes Shrine, which leads Rotor's pragmatic, no-nonsense attitude to clash with Sonic's nonchalant, selfless nature. However, they are always back by each other's side in a pinch.

Nicole the Holo-Lynx
Nicole is Sonic's helpful and trustworthy computer friend. She helped Sonic gain Tails, Rotor, Antoine, Bunnie, Amy and Sally's old memories from the original timeline, although she also gave the evil wizard his old memories back as well. She aids alongside the gang in her Lynx form and her body gives her all the power she needs to aid the gang.

Professor Charles the Hedgehog
Charles Hedgehog is something of an "uncle"-like figure to Sonic. Sonic has on more than one occasion demonstrated a willingness to protect Chuck at all costs; when the latter had passed out during Sonic's battle with E-106 Eta, Sonic quickly grew enraged.

Knuckles the Echidna
Knuckles the Echidna is one of Sonic's greatest rivals and best friends. They have known each other for a long time, but their relationship is somewhat complicated. Sonic and Knuckles are much like oil and water. While Sonic exemplifies the wind, laid-back, cool and free, Knuckles is the mountain, stern, serious and unmovable, which cause them to argue a lot. Because of their differences and morals, they do not understand each other and they do not always see eye to eye. While Knuckles at times rebuts his help and claims he could do better, Sonic just rolls with it and is merely glad to help him.

Sonic always welcomes a challenge from Knuckles and enjoys teasing him for fun because of his serious nature, and will even try getting him angry so he can fight him. Despite their differences, the two of them are connected by a hot-blooded friendship, and have joined forces many times.

Shadow the Hedgehog
When Sonic and Shadow first met, they started out as enemies, each trying to stop the other from achieving their goals (Sonic was trying to save the world while Shadow tried to destroy it via the Eclipse Cannon). However, when Shadow discovered he had been mislead by fake memories, he and Sonic joined forces to save the planet. Since then, they have remained arch-rivals, but also comrades, and have helped each other out on numerous occasions.

When Shadow had presumably perished after the destruction of Letter of Gabriel, Sonic felt sadness for his arch-rival's demise and used it to further motivate himself to take down Sigma, who indirectly caused this. After the timeline was reset, Sonic immediately called and checked up on Shadow, and was elated to find him alive.

Silver the Hedgehog
Like with Knuckles and Shadow, Sonic's relationship with Silver had gotten off to a rocky start (although the events of their initial meeting were erased from the timeline); the two were enemies, and Silver stopped at nothing to eliminate Sonic, having been tricked into deeming him responsible for the destruction of his timeline. However, upon realizing he was tricked, he joined forces with both Sonic and Shadow to defeat a super-dimensional threat.

Even though he and Sonic are now allies, Silver still tends to get irritated by the former's cheeky attitude, such as when Sonic decides to make some puns during their second encounter with the Ifrit. Like Knuckles, Sonic will occasionally tease Silver for his core traits, although the two share very similar morals.
