Sonic the Hedgehog

Sonic was born during the early days of the Great War to the loving couple Jules and Bernadette Hedgehog in Mobotropolis. While his parents originally named him after his grandfathers, Sonic quickly picked up his nickname due to his incredible speed which he would use to run everywhere. As a toddler, both of Sonic's parents fell victim to the Roboticizer, forcing his uncle to raise him. Sonic first met Sally Acorn during one of his uncle's many visits to King Maximillian Acorn. When the King realized the Great War was going badly for the Mobians, he ordered a large number of the children in the city, including his daughter and Sonic, to the sanctuary in Knothole Village under the protection of Rosie and Julayla. Only a few months after the Great War's end, Warlord Julian launched a full scale coup d'état and took over the city, renaming it Robotropolis. During his takeover, Sonic's uncle Chuck and pet dog Muttski were captured and roboticized as well, effectively making Sonic an orphan.

Over the years, Sonic struck back against Robotnik's growing empire, assisted by his friends Sally, Rotor the Walrus, Antoine D'Coolette, NICOLE and Miles "Tails" Prower. Modeling their group after the Original Freedom Fighters, Sonic and his group of Knothole Freedom Fighters used guerilla tactics and espionage to ruin many of Robotnik's schemes, including the release of Krudzu into the Great Forest and the partial roboticization of Bunnie Rabbot. After ten years of Robotnik's reign, Sonic and his group of Freedom Fighters had begun to increase their attacks against the evil despot. Up to this point, Robotnik had thought of their resistance as no real threat, and let it exist within the Great Forest. However, he now realized that the Knothole Freedom Fighters were not only older and more organized, but had years of experience as guerilla fighters under their belt. He now made it a priority to locate the secret location of Knothole Village so that he could crush the Freedom Fighters quickly. Time and time again however, he plans were foiled by Sonic the Hedgehog and his crew.

While most of his time was spent combating Robotnik and his hordes of SWATbots and Badniks, Sonic encountered other villains to combat. At one point, while on the other side of Mobius, Sonic attempted to get to Robotropolis quickly using the Cosmic Interstate, which lead him to the parallel universe of Anti-Mobius (now called Moebius). During his brief time in this realm, Sonic encountered his alternative self, Evil Sonic. Although he quickly defeated his evil double, and was able to get back to his home realm, Evil Sonic would continue to pose a threat to his reality in the future.

During one of his missions with his young friend Tails, Sonic encountered the Floating Island, home of Knuckles the Echidna, while flying in their plane "The Tornado". At the time, Knuckles the Echidna had been coerced by Robotnik to assume Sonic and Tails were after the Chaos Emerald. While Knuckles was distracted trying to apprehend Sonic and Tails, Robotnik was able to briefly take the Chaos Emerald for himself. Upon realizing he had been tricked, Knuckles, Sonic and Tails teamed up and retook the Emerald from Robotnik.

Some time later, another reality's version of Sonic, called Cyborg Sonic, came in his universe using the Cosmic Interstate, trying to gain help from Sonic the Hedgehog to stop his own version of Robotnik, called Robo-Robotnik. With the help of numerous reality's Sonics, and the unexpected assistance of the original Dr. Robotnik, Robo-Robotnik was stopped from taking over all the universes.

Robotnik later planned a trap for Sonic, capturing the hedgehog's number one fan, Amy Rose. Using her as a hostage, Robotnik was able to lure Sonic into the Collision Chaos Zone where he would be forced to race against Robotnik's newest creation, Metal Sonic. Although the overweight despot had numerous traps hidden throughout the race course, Sonic was able to survive, and caused Metal Sonic to overheat, destroying his legs and causing him to crash. The rest of the Freedom Fighters went on the free Amy and Tails, who had also been captured.

At one point, Sonic wished to undergo roboticization while using Rotor's invention, the Neuro-Overrider, to maintain his free will so that he could destroy Robotnik and Robotropolis with his enhanced abilities. The plan was denied by Sally, much to the dismay of Sonic. However, Sonic was captured by the bounty hunter Nack the Weasel and roboticized by Robotnik anyways. With his free will almost completely gone, Mecha Sonic was sent on a mission to destroy Knothole Village entirely. Although he succeeded in damaging a large part of it, he was unable to transmit the coordinates of its location, as he was engaged in combat with Bunnie Rabbot. While he managed to overcome his former cybernetic friend, the assistance of Knuckles, who had roboticized himself and became Mecha Knuckles, proved too much. The two had crashed into Robotropolis and badly damaged it, but Mecha Knuckles, having come out with less damage, took Sonic back to Knothole to be healed before Robotnik could repair him. Sonic was restored to his former self when Sally used the magical powers of Sonic's one billionth Power Ring. Afterwards, Sonic was tried in court by Antoine for treason, but was proven innocent once it was revealed Nack the Weasel was responsible for capturing Sonic.

Some time after the failure of Mecha Sonic, Robotnik finally decided to enact his ultimate plan to destroy Knothole Village and the Freedom Fighters - Operation: EndGame. Robotnik's secret agent Drago Wolf (a former member of the Wolf Pack) was able to fool Hershey the Cat into killing Princess Sally, while the other Freedom Fighters believed it to be Sonic who did it. Additionally, Robotnik had replaced the recently rescued King Max with a robotic duplicate, who would be used to misdirect the Freedom Fighters. With the Freedom Fighters believing Sonic to be a traitor and ordered to arrest him, Robotnik would be able to prepare his super weapon, the Ultimate Annihilator, which would erase Knothole from existence. When the Freedom Fighters discovered Sonic was innocent, they allowed him to attack Robotnik while they attempted to combat the swarms of SWATbots and COMbots now within Knothole. Once in Robotropolis, Sonic and Robotnik engaged in hand-to-hand combat. Due to Snively's treachery, the Ultimate Annihilator was reprogrammed to only target the war room and Robotnik's DNA signature, erasing him from existence, thus ending the battle and ending the ten year reign of the dictator.

With Robotnik's reign of terror now over, Sonic the Hedgehog and the rest of the Freedom Fighters were able to retake Robotropolis. Although Snively attempted to maintain control of the city and combat the Freedom Fighters using a DYNAMAC, he was quickly defeated by Sonic and company. With the city completely under control once again, Sonic was able to search the city for his uncle Chuck and the other Robians. Upon locating his uncle, Sonic soon realized his parents were alive when he met them for the first time since his early childhood years. In order to prevent having to tell his nephew that the roboticization was his fault, Chuck had told Sonic his parents had died during the Great War. Angered at the discovery, Sonic left, unwilling to speak to either his uncle or his parents for some time.

Now that the real King Max was located and had returned to power (although still suffering from the crystallization effects he suffered from leaving the Zone of Silence), he had begun leading the free Mobians once again. Two of his first orders however was disbanding of the Freedom Fighters and later the dismantling of all the Robians, who wished to start their own colony and civilization outside of Mobotropolis due to feelings of disdain from their Mobian counterparts. It was soon discovered that Max was being controlled by the wizard Ixis Naugus, who had been attempting to take control of Mobotropolis upon his own escape from the Zone of Silence. With his plans foiled, Naugus escaped from the city and King Max was finally restored to full health.

Sonic and the Freedom Fighters were briefly sent to the Floating Island, upon receiving a call from Locke the Echidna, Knuckles' father. Almost immediately after arriving, Sonic, Tails and Knuckles were transported to another zone by the now all-powerful Mammoth Mogul, who became virtually omnipotent after stealing the powers from Enerjak using the Sword of Acorns. Although his powers were great, the combined might of Super Sonic, Hyper Knuckles and Turbo Tails, as well as assistance from Athair, proved too much, and he was imprisoned within the newly formed Master Emerald.

With Naugus freed and plotting his revenge, Sonic and Tails were ordered to search the planet, track him down, and reseal him within the Zone of Silence. Over the next few months, the two went from the lush lands of the Great Forest, to the outback of Downunda, to the desert lands and Sand Blast City, to the Kingdom of Mercia and finally to the frozen lands of the Southern Tundra. Eventually, Sonic and Tails, with the help of over a billion power rings, defeated a also super powered Naugus and trapped him within the Zone of Silence once again with the help of Nate Morgan and Eddy the Yeti, the latter sacrificing his life to save Sonic, Tails, and Nate from Nate's collapsing castle.

With Naugus trapped away, Sonic and Tails returned to Mobotropolis. While the Mobians were able to enjoy a short time of peace, they soon realized another threat was looming over them. For months, the planet had been plagued with a variety of events which seemed too random to be normal acts of nature. It became apparent that someone was responsible for these when a broadcasted message from King Max was interrupted and replaced by a history of the life of Robotnik. It was discovered by NICOLE, Sally's hand-held computer A.I. that the message was delivered from a number of satellites orbiting the planet. While everyone assumed them to be abandoned projects of Robotnik and no real threat at first, they soon realized this was not the case when all of the Robians disappeared overnight.

Enraged by the disappearance of his family, Sonic took it upon himself to discover what was going on with the satellites. Despite her father's orders, Sally chose to help Sonic go through with his plan by reforming the Freedom Fighters. With the discovery of a space shuttle within Mobotropolis by Nate Morgan and Rotor the Walrus, which was originally created by Robotnik prior to his death in order to expand his empire beyond the planet, the Freedom Fighters used a Power Ring to power it enough to get into orbit. Once inside the massive satellite structure, which was formed when all of the satellites merged together, Sonic and his friends discovered a horrifying sight - Doctor Robotnik was still alive!

After a brief fight between Sonic and the evil dictator, it was discovered that this was not the late Dr. Robotnik who had been erased by the Ultimate Annihilator, but rather the roboticized version from another reality, Robo-Robotnik. Having barely survived his confrontation with the various Sonics nearly a year ago, Robo-Robotnik had managed to rebuild his body using a part from the Giant Borg machine. He then went on to nuke the city of Mobotropolis in his reality and destroy Cyborg Sonic and the Freedom Fighters. With no opposition in his own reality, and discovering that Dr. Robotnik had died in the prime zone, Robo-Robotnik traveled through space and time to replace his deceased alternative self in that reality.

When the Freedom Fighters confronted Robo-Robotnik, they soon discovered that their coming to the satellite base had been a trap, designed to lure them away from Mobotropolis to allow Robo-Robotnik's Shadowbots to reclaim the city and capture its population for roboticization. While many were still able to escape the city, all of the Robians, with the exception of Sonic's parents, whose wedding bands consisting of Power Rings prevented them from losing their free will, were now under Robo-Robotnik's control. Sonic and the Freedom Fighters were able to destroy the satellite base with the help of Snively, and escaped on the space shuttle back to Mobius. Robo-Robotnik however simply downloaded his consciousness into a new robotic body, located in a secret sub basement located a half mile under the former Castle Acorn in the re-christened Robotropolis.

With Robotropolis now in control of Robo-Robotnik, the Mobians fled the city to Knothole Village. With his new body, Robotnik renamed himself Dr. Eggman, and planned on downloading the location of Knothole Village into his mind. Before he was able to however, Sally, NICOLE and Snively deleted its location from Robotropolis' computer memory banks, preventing its location from being discovered by the new despot. Meanwhile, Sonic located the remaining Mobians who were trapped in the city during its evacuation, and helped them escape.

When Dr. Eggman released Chaos from the confines of the Black Emerald, which was then sent to the human city of Station Square, Sonic and the other Freedom Fighters were sent to stop it. While Sonic and Knuckles seemingly killed Chaos onboard the Egg Carrier, the water-created being managed to survive and obtain the last of the seven Chaos Emeralds, using the negative energy to becoming Perfect Chaos. With the creature wreaking havoc in Station Square, Sonic was forced to use the remaining positive energies of the Emeralds to become Super Sonic to combat the new threat. He successfully defeated Perfect Chaos, who then returned to his confines in the Black Emerald along side Tikal. The humans in Station Square thanked the Freedom Fighters for their help.

Before they could return to Knothole, Dr. Eggman launched another mechanical duplicate of Sonic, known as Silver Sonic II, to destroy Station Square once and for all. While Silver Sonic II was able to outmatch the other Freedom Fighters with ease, his injuring of Tails pushed Sonic over the edge, allowing him to defeat the robo-duplicate by knocking its head off. When Eggman went to recover his machine, he found himself being attacked and chased out of Station Square by it, as Nate Morgan had reprogrammed Silver Sonic II to act as protector of the city against the mad scientist.

With Station Square safe and with a permanent protector there, Sonic and the Freedom Fighters bid the humans farewell. Shortly after their departure in the Freedom Fighter Special however, the ship experienced a malfunction and was forced to land. Little did they know that the one responsible for this was none other than the original Metal Sonic. During their reconnaissance of the area, Tails was captured and taken hostage by the metallic duplicate. Sonic, angered as the capture of his young friend, attempted to defeat Metal Sonic alone. However, the self-rebuilt robot proved far too powerful, cunning and advanced, due to the Power Gem embedded in his chest. After defeating Sonic, Metal Sonic offered the blue blur the chance to save Tails, which turned out to be a trap to lure him into Mount Mobius just before it erupted. Just as the volcano began to spew lava, Metal Sonic had a change of heart, after witnessing Tails willing to stay with Sonic and sacrifice himself. The robot then held the lava back while the two could escape before being overwhelmed by lava.

Shortly thereafter, Sonic returned home only to aid King Max in rescuing Prince Elias Acorn from Dr. Eggman. During the fight, Sonic saw the king use the Sword of Acorns to unintentionally restore free will to his uncle Chuck and Muttski. The distraction of the sight was enough to keep Sonic from protecting King Max from a sneaky punch from a Shadowbot, leaving King Max wheelchair bound for months. Feeling guilty from his lapse in judgment. Sonic took the Sword (unauthorized) in an attempt to restore the other Robians, only for Mina Mongoose to follow with a similar plan to rescue her mother. During a subsequent battle with upgraded Combots, the Sword was lost.

Attempting to retrieve the Sword from Dr. Eggman (unaware that Uma Arachnis had taken it during the battle), Sonic witnessed the return of the Overlanders. Attempting to reason with them, Sonic unsuccessfully protected the Overlanders from Monkey Khan and failed to stop the Overlanders from fleeing into Robotropolis. To make matters worse, Sonic had to answer for his actions regarding the sword, lost his knighthood, and was temporarily restricted to Knothole.

Weeks later, he took another unauthorized trip to Robotropolis, saw that Eggman had done nothing to them, then had to intervene in a battle between Arachnis and Kodos. After Arachnis curiously saved Sonic from Kodos and departed, Sonic secretly delivered Kodos to the Knothole hospital. The next morning, a Shadowbot delivered a message for Sonic: Sir Charles had regained his free will, and knew that Eggman had lost the sword to Arachnis. Adopting a disguise, and going by the alias, "The Sneak" of Sand Blast City, Sonic attempted to track down Arachnis, only for Geoffry St. John and the Royal Secret Service to head to Robotropolis, thinking that the sword was still there. Sonic had to rescue them from Dr. Eggman, and head back to Knothole before anyone recognized him.

Just as Sonic stashed his disguise, he was apprehended by Station Square's defense force G.U.N., when they believed it was Sonic who destroyed Silver Sonic II and stole the city's only Chaos Emerald from their bank. It turned out that the real thief was Shadow the Hedgehog, a being created by Dr. Robotnik's maternal grandfather Professor Gerald Robotnik. Sonic managed to escape his captors and eventually defeat Shadow, restoring his reputation in the city of Station Square. Eventually returning home, Sonic acted as a tutor for Mina, before making one more attempt at retrieving the sword. With help from the other Freedom Fighters, the sword was finally retrieved. Almost immediately, it was discovered that Nate Morgan had learned of the Overlanders, and the toxic waste poisoning in the city, forcing a few rescue attempts. The Sword was able to restore free will to the Robians, including the High Sheriff, who was returned to Knothole by Antoine, but Nate Morgan was captured and roboticized, and Sonic was unable to rescue him. Instead, he was forced to stop a treasonous Heavy and Bomb from killing the Royal Family, before convincing the Overlanders that they can't stay in Robotropolis.

Some time after this, Sonic would be called back to Station Square to save them from Zan the Dragon, in exchange for letting a group of Overlanders move into the city from Robotropolis.

Some months later, the xenophobic alien race known as the Xorda came to Mobius. They went on to explain that Mobius used to be called Earth, and that thousands of years ago, they sent an emissary to the human population to discuss a peace agreement, only for it to be killed and dissected. In retaliation, the Xorda attacked Earth, launching Gene Bombs on the planet, which lead to the de-evolution of humans and the evolution of the animal kingdom. They had now returned to the Earth to finish the job the Gene Bomb was supposed to do, which was to wipe out all life on the planet. Their ship's attack on Mobius was short lived, but the Xorda had one weapon left in their arsenal - the Quantum Dial. The Quantum Dial was a massive device which would open up a black hole, enveloping the planet and the entire solar system. Although almost all of the people of Mobius attacked the huge weapon together, its defenses proved too great. It was only when Knuckles, who had just returned from the afterlife, took out the weapon's entire defense systems, that Sonic was able to get into it and shut it down, saving the entire planet. However, by shutting it down, Sonic was transported billions of light years off world to another galaxy.

Realizing he was trapped on the other side of the universe, Sonic spent the next few months jumping across worlds while searching for a way home. He first found himself on the planet Thoraxia, whose population consisted of two insectoid-like races, the Blodex and the Bzzzz. Before Sonic could find a way off the planet, he found himself having to use the Red Chaos Emeralds on the planet to defend the Blodex from the invading Bzzzz. However, rather than turning Sonic into Super Sonic, the Red Emeralds manifested the power Sonic absorbed into a separate being which became Super Sonic. The new being defeated the Bzzzz, but didn't stop there. Instead, it went on a total rampage and began destroying the Blodex as well. Realizing he was responsible for the creation of this new menace, Sonic went to fight Super Sonic and stop him from causing any more harm. After stopping Super Sonic from destroying Thoraxia's two moons, Super Sonic went on to pummel Sonic. Like the Chaos Emeralds on Mobius however, the power was only temporary, causing Super Sonic to dissipate before he could finish Sonic off.

After saving the Blodex, the insect-like race contacted a neighboring species called the D'novulands to assist Sonic's trip home. The D'novulands placed a device in Sonic's ear, the "Babble Node" as Sonic referred to it, allowing him to understand almost all alien languages. On their way to Mezzo Jillion, the sector's largest trading hub, their ship was caught in an asteroid field, the remains of the planet Cemerant-16, which had just been destroyed. Forced to abandon ship, Sonic was sent into the last escape pod by the ship's captain, Oe, which descended into an uninhabited planet's atmosphere. The planet's evolution and time was hundreds of times faster than that on Mobius, allowing Sonic to watch the planet go from uninhabitable to supporting a technologically advanced race called the Azurites. The Azurites had watched Sonic for what had been millions of years for them, believing him to be a god. When they were technologically advanced enough, they created a device known as the Temporal Decelerator, which allowed them to slow down their time so that they could communicate with Sonic. With communication now possible, the Azurites offered to make Sonic a ship which would allow him to get off the Azurites world and find his way home. Once they disabled the Temporal Decelerator, they were able to create a ship within a matter of seconds by Sonic's time. Sonic then used the ship to begin his journey home.

Sonic's journey lead him to meet up with one of the late Dr. Robotnik's earliest creations - E.V.E. Having convinced E.V.E. to go beyond her programming, Sonic managed to persuade the machine to ascend to the stars. Little did he know this would cause a chain of events leading to the destruction of numerous worlds. Now, almost two years after E.V.E. had left Mobius, her size was nearly that of a planet's, with the power to drain entire worlds of all their metallic substances within fifteen minutes. After a confrontation with Captain Bagbar Beeblebrox and the crew of the Sentelle, Sonic, realizing it was his duty to make amends to stop E.V.E., flew his ship into her hull. Fighting his way through E.V.E.'s defense units, Sonic finally came face to face with her. Sonic managed to convince E.V.E. that her actions made her no better than she was when she first left Mobius, which caused her to decide to collide with the nearest sun and destroy herself.

During his time in space, Sonic located Tails' parents on the Bem homeworld of Argentium - Amadeus and Rosemary Prower. Both had been taken by the Bem Ceneca-9009 during Robotnik's original takeover, and Amadeus was de-roboticized. Both had been taken back to the Bem homeworld where they had been living ever since. After breaking Ceneca-9009 out of prison, Sonic was provided with a ship to take him through the Bem's artificial wormhole back to Mobius. The ship however was too small to bring Ceneca-9009 or Tails' parents along, forcing Sonic to return alone.

Having finally made it back home, Sonic quickly landed. To his surprise however, much had changed in the short time he was gone. While it was mere weeks for Sonic in space, back on Mobius over a year had passed. In Sonic's absence, Dr. Eggman had declared full-scale war on both the Kingdom of Acorn and the Republic of Station Square. To make matters worse, Eggman had developed two nuclear warheads which he was preparing to launch at both cities. In addition to this, he deployed an army of new-model SWATbots to take out the shield surrounding the radioactive wasteland of Robotropolis, which would result in the waste poisoning Knothole.

After a quick welcome home reception with friends and family, Sonic and the Freedom Fighters departed immediately to stop Eggman from launching the warheads, while the Chaotix, Amy Rose and G.U.N. went to stop the robotic hordes from taking down Robotropolis' force field. In the harbor of Old Megaopolis, Sonic first encountered Eggman's robotic "daughter" Mecha, while Tails struggled to outsmart Eggman's computer-virus "son" A.D.A.M.. Shortly before the missiles launched, Bunnie successfully destroyed the aircraft carrier which was harboring them, though this was only due to the fact that Tails distracted A.D.A.M. long enough for her to act.

Shortly after this, Sonic spent time getting used to his old home of Knothole with friends. The next few days however proved just as difficult for the blue blur. Sonic and Sally suffered a heart-wrenching breakup, and Sonic's father was temporarily killed by a Tommy Turtle Auto Automaton. However, things took a better turn when Sonic and Sally found the real Tommy Turtle and rescued him from Dr. Eggman's clutches.

When Knuckles received word that his father Locke had been captured by the Dingo Regime, which placed the location of the Master Emerald in jeopardy, Sonic accompanied him and the Chaotix to Angel Island to launch a rescue mission. Sonic's assistance resulted in the liberation of one of the many concentration camps and the successful rescue of Locke.

Shortly afterwards, Sonic found himself pursuing Shadow the Hedgehog into a mysterious underground bunker. Unbeknownst to him, Dr. Eggman was equally interested in this bunker, and sent the recreated Metal Sonic to discover its secrets as well as defeat both Sonic and Shadow. The trio went head-to-head while Tails and the other Freedom Fighters discovered the history of Mobius from the ancient robot Isaac. Eventually, Metal Sonic and Isaac allied while Sonic and Shadow formed a temporary alliance in order to stop Isaac from launching a nuclear missile. With Shadow's help, Sonic managed to prevent the missile from launching and defeated Metal Sonic.

Using a device created by Anti Rotor, Evil Sonic managed to transport himself to the prime zone and knock Sonic unconscious. He then dressed himself in Sonic's attire while dressing Sonic in his and dumped him in Anti Mobius while replacing Sonic in the prime zone. Upon awakening, Sonic woke up to the Anti Freedom Fighters beating on him. Shortly afterwards however he managed to subdue them and use Anti Rotor's device to return to the prime zone. However, even after his defeat, Evil Sonic managed to remain in the prime zone.

On Sonic and Anti-Sonic's birthday, Anti Sonic attempted to obtain the Master Emerald with the help of Rouge the Bat. Locke fought them off, but was nearly defeated when Anti Sonic decided to fight dirty and used weapons. Locke managed to prevent the evil duplicate from using the Master Emerald to transform completely, though a partial transformation mutated Evil Sonic into the being soon to be known as Scourge. With his new powers, Scourge fought both Sonic and Shadow back at Knothole Village; despite having the upper hand, the duo proved too much for Scourge and he fled, with Rouge, into a mysterious Warp Ring.

Following the Scourge fiasco, Sonic and the other Freedom Fighters were surprised to see Tails' uncle Merlin Prower arrive on the scene with Sir Connery. Merlin was hoping to use the powers of the Source of All from King Max's crown to ensure Mammoth Mogul remained trapped inside a Chaos Emerald. Before he could do this however, the Arachne released Ixis Naugus from the Egg Grape Chambers, the dimensional breach killed the Ancient Walkers and allowing Mammoth Mogul to escape confinement. Soon afterwards, Sonic, the Freedom Fighters, the Chaotix, Merlin and Sir Connery found themselves facing off against the Destructix, the Arachne, Ixis Naugus and Mammoth Mogul. When Sir Connery sacrificed himself to render the Sword of Acorns and the Crown of Acorns powerless and wound Mammoth Mogul, the tides seemed to shift into the allies' favor. However, Dr. Eggman's Egg Fleet soon arrived on the scene and captured Mogul, Naugus, the Destructix and the Arachne, sending them to the Egg Grape Chambers. Sonic assumed Eggman would continue his attack, but Eggman stated he would crush Sonic and the Freedom Fighters on his own terms before returning to New Megaopolis.

Following the capture of Mammoth Mogul and his followers, Anonymous revealed himself to in fact be Dr. Eggman's computer-virus "son" A.D.A.M. Before Eggman could erase A.D.A.M.'s programming, the latter transferred his files to the nanites. A.D.A.M. then proceeded to use the nanites to control Sonic's father Jules into bringing Tails to his super beacon, while forcing Eggman to contact Shadow to arrive there as well. A.D.A.M. then had both Super Shadow and Turbo Tails locked inside the beacon and used their immense powers to pull all of the Chaos Emeralds from throughout the universe to Mobius.

Sonic had followed his father to the beacon and moved in to stop A.D.A.M. before he could complete his schemes, Sonic using the Chaos Emeralds to transform into Super Sonic. Though Sonic had the upper hand against A.D.A.M. even when the latter used the Chaos Emeralds to transform as well, Sonic found himself unwilling to attack Tommy Turtle, who A.D.A.M. was using as a host body as Tommy had come into contact with the nanites. Fortunately, Tommy managed to briefly gain control of his body and tell Sonic to let him die. The Egg Fleet soon arrived on the scene and Tommy was subsequently killed in front of Sonic's eyes. Shortly before his death, Tails and Shadow used their Chaos powers to open a portal to the Zone of Silence and send all of the Chaos Emeralds into that zone, thus causing The Great Harmony.

Not long after A.D.A.M.'s destruction, Eggman finally decided to use the Egg Fleet and destroy Knothole. When the invasion of Knothole began, Snively began by attacking Freedom HQ, sending everyone but Sonic, Knuckles, Tails, Amy and NICOLE to the Egg Grape Chambers. While the latter four were trapped under the rubble of Freedom HQ, Sonic ran as quickly as he could to warn the others of the invasion. Just as he arrived at the front gates, the Acorn Castle exploded. Emerging from the wreckage was Dr. Eggman in his Egg Beater battle armor. Eggman proceeded to insult Sonic while utterly beating him. Sonic, pushed to the edge, attempted to take out the Egg Beater with a single attack by running at it at full speed from the other end of the continent. The attack merely dented the Egg Beater's shield, and Sonic was left bruised and beaten as Eggman left him in the ruins of Knothole.

Sonic refused to accept defeat however, and had originally intended on rescuing everyone by himself, telling Tails and the others to remain behind where they would be safe. Tails, furious at this, lashed out at Sonic. The two's bickering was interrupted by NICOLE, who stated she had a plan. The five headed out on a saucer-shaped vessel created by Tails to New Megaopolis to rescue their friends and families. Just as they arrived at the Egg Vineyard, Charmy Bee's Egg Grape Chamber was activated. However, Sonic managed to break him free just in time to prevent long-term damage. After Knuckles and Amy freed everyone from their Egg Grape Chambers, Eggman returned to the scene to prevent their escape. Unbeknownst to him, NICOLE, who had managed to take control of the former nanite city, also altered the weapons on the Egg Beater and Egg Fleet to transport the Mobians to the newly formed city of New Mobotropolis instead of back to the Egg Grapes. Sonic managed to distract Eggman long enough for NICOLE to change the programming, then allowed himself to be transported along with the others to New Mobotropolis.

Not long after being transported to their new city, the Mobians found themselves relying on the city's shields to protect them from the attacking Egg Fleet. Sonic decided to challenge Eggman once again, this time with assistance from the Knothole Freedom Fighters and the Chaotix. Their combined might allowed them to defeat the Egg Beater, which was designed specifically to fight Sonic. Eggman then fled the scene.

Sonic, having previously been dating Fiona Fox, caused a strain on his and Tails' friendship. This became even when it was revealed that she preferred the evil Scourge over the good Sonic. This stress ultimately caused the two to be on opposite sides of a political schism in the Kingdom of Acorn, Tails supporting the side led by his father and Sonic remaining loyal to the House of Acorn. When Tails helped his mother break Amadeus out of jail, long suppressed hostility was released as he and Sonic fought with each other.

Tails was quick to bring up his fury at Sonic's lack of sensitivity, and refused to explain it to the baffled Hedgehog since he felt that Sonic would probably just ignore what he was saying again. Finally, the young Fox revealed that his main dispute with Sonic was over Fiona and Sonic's seeming dismissal of his feelings for her, and Sonic admitted that he had known about Tails' feelings and apologized, explaining that he had hoped that it would help Tails get over his crush. Reconciled, the two headed off to stop a duel between Amadeus and Elias Acorn, only to find out that Sally had beaten them to it.

Following the battle with Tails and the creation of the Acorn Council, Sonic found himself facing off against Dr. Eggman's newest creation, the Egg Nautilus. Eggman had hoped to use the tentacles of his new machine to implant a virus into NICOLE and erase her. Sonic was able to stop Eggman's attempts by informing him that Enerjak was about to return. Eggman, realizing this posed a much more serious threat, formed a temporary alliance with Sonic so the two could stop the returning Enerjak. Shortly after Eggman departed, NICOLE informed Sonic there was trouble at the Acorn Airport. Racing over there, he found the Chaotix attacking the guards and demanding they be allowed to leave in order to find the missing Knuckles. After fending off against them, Sonic soon realized that the Chaotix should be free to search for Knuckles, and ended the fight. To satisfy both Sally's wishes for the Chaotix to remain within the safety of New Mobotropolis, and Julie-Su's desire to find Knuckles, Sonic and Tails were sent out on the Tornado 2 to Angel Island.

Sonic and Tails arrived at Angel Island hoping to find Knuckles. Realizing Knuckles was not at the chamber of the Master Emerald, they began searching the rest of the island. Soon they found that Enerjak had already been reborn and had not only completely removed the Dingo Regime and killed Kage Von Stryker, but had removed all of the Dark Legion's cybernetic enhancements and teleported the vast majority of surviving Echidnas to the ruins of Albion. Just before Sonic could attack him, Enerjak teleported away to New Mobotropolis. Sonic contacted New Mobotropolis before picking up Tails and racing back as fast as he could. Sonic and Tails arrived back at New Mobotropolis just in time to see Enerjak there, who had already disabled the city's shields.

Shortly after Sonic arrived back in New Mobotropolis, he found himself beside Shadow the Hedgehog, who had responded to Sally's distress call while Sonic and Tails were on Angel Island. Both Sonic and Shadow attempted to face off against Enerjak, but were no match for the Chaos demigod. It was during this confrontation that Sonic discovered Knuckles actually was Enerjak, and was under the influence of Dr. Finitevus. After being beaten by Enerjak, Dr. Eggman arrived on the scene and transported the Chaos demigod to the Egg Grape Chambers to use as a living battery to power his city. Before Sonic and the others could come up with a plan to rescue Knuckles, he and Julie-Su were pulled onto Angel Island via Warp Ring by Knuckles' father Locke, who had recruited the two to defeat the Destructix and retrieve the Brotherhood of Guardians special weapon to stop Enerjak.

Sonic, Julie-Su and Locke managed to evade the Destructix with the help of Archimedes and located the secret weapon. Instead of allowing it to be used however, Sonic destroyed it, since its use would have not only stopped Enerjak, but caused Knuckles' death. Sonic quickly headed towards the Master Emerald and used its power to transform into Super Sonic before Enerjak had a chance to recharge. With his new invulnerability and suport powers, Super Sonic went head to head with Enerjak. While Enerjak was distracted battling Super Sonic, Locke sacrificed his own life to break the hex Dr. Finitevus placed on the Master Emerald. This resulted in Knuckles losing his powers and returning to normal.

After the Enerjak rampage Sonic's former love interest, Mina Mongoose, finally returned from her world tour. Ash Mongoose, Mina's boyfriend, apologized to Sonic for being a jerk to him back when he thought Mina was still in love with him. Sonic then took Mina to the ruins of Knothole and to the new Freedom HQ. NICOLE told Sonic that Mammoth Mogul wanted to see him at the detention center. Sonic went there only to be told to allow Mogul to be released, otherwise he would make a new Fearsome Foursome. Sonic, who thought this was a joke, chuckled and left. While everyone was sleeping however, Mogul used his powers to call upon the ones he had "marked" in the past. This included Mina, Mighty the Armadillo and Tails. The fourth member would be a convinced Sonic. With Sonic's friends now under mind control, Mogul attempted to have them defeat Sonic.

When they were unable to do this, Mogul threatened to have them all commit suicide, Tails by flying too high until he ran out of oxygen and fell to his death, Mina would run out into the middle of the ocean then stop and drown, and Mighty would march into New Megaopolis, defenseless and be killed by the Dark Egg Legion. Sonic understood that Mogul had him cornered and unless he did as Mogul asked his three friends would die. Mogul offered to return Sonic's three friends in exchange for the Chaos Emerald held in New Mobotropolis. With the help of Ash, Sonic retrieved the emerald and gave it to Mogul. Surprisingly, the tyrant kept his word. With the power of the Chaos Emerald merged with him, Mogul regained his powers. He freed the other prisoners in New Mobotropolis and explained to Sonic that, while he senses fate will not allow him to defeat Sonic once and for all, he is immortal once more and will spend his time making Sonic's life miserable. On that note, he vanished with the others.

Mogul then took over Robotnik's old Casino Night Zone and changed it to his own image. Rouge the Bat and Geoffrey St. John were working togheter to keep a eye on Mogul and his casino, which was a great success. Scratch, Grounder and Coconuts along with other outdated Badniks were recruited by Mogul as well as the Destructix. Mogul said to the Destructix that he will pay them handsomely for Sonic's shoes. He told them that it was up to them if his feet were still in them. Meanwhile Tails' uncle Merlin removed Mogul's curses from Tails, Mina and Mighty. Additionally he purged any possible curses from Sonic and Knuckles, stating he wanted to ensure that the hex Dr. Finitevus put on the Master Emerald didn't have any lasting effects. Following Merlin's departure, Sonic spent some time talking alone with Sally about their past and feelings for one another. Their conversation was interrupted by Bean and Bark and the Destructix. Eventually, Sonic was knocked out by a shot from Nack the Weasel, who then gave Sally ten seconds to run for help while Sonic was dragged off by the Destructix. Sonic was soon liberated by Sally Acorn, Amy Rose, and Geoffrey . When the heroes confront Mogul however, he denies all claims of wrong-doing as his accusers lack any incontrovertible evidence. Sonic and his friends were then sent away, publicly humiliated.

Following the Casino Night fiasco, Sonic, Knuckles and the Chaotix were sent to New Megaopolis to deal with the Dark Egg Legion. During their absence, the Suppression Squad came to Mobius Prime via the Star Posts and began attacking Freedom HQ. The Chaotix felt they could deal with the Dark Egg Legion alone, and sent Sonic back to Freedom HQ in response to their distress call. However, after Sonic left, Dimitri showed up in a massive robotic body looking like a praying mantis, to which Vector stated it was likely not a wise idea to send Sonic away after all. Sonic arrived back at Freedom HQ just as Scourge, self-declared King of Moebius (formerly known as Anti-Mobius) following his successful invasion of the planet, emerged. Sonic and Scourge battled, as did the rest of their respective gangs. Unfortunately, they found themselves matched blow-for-blow, and the repeated use of energy weapons took it's toll on the base. Rather than loose the base (and by extension their lives), Sally convinced Sonic to have them retreat. Scourge's taunting, however, enraged Sonic to the point he assured his friends and the Chaotix, returning from their successful mission, the Squad would only occupy the base temporarily.

A couple of days later, Sonic, having rested up and prepared for a counterattack, went before the Acorn Council with Knuckles, only to find them in debate over whether to re-take Freedom HQ. In the end, the Council (save for Uncle Chuck and Rotor) voted to focus their attacks on the weakened Eggman Empire and re-take the base later. Sonic refused to accept their decision, and later prepared to take the base back with Knuckles. Sonic was surprised to find Knuckles supporting the Council. His efforts to convince him that he privately didn't agree with them and he must do what he thought was right led to Knuckles yelling at Sonic that he already did so, and now his father was dead, and walk away in tears, telling Sonic to do what he wanted. Sonic decided to take Freedom HQ back on his own. As he arrived at Freedom HQ, Sonic discovered Scourge was battling a new version of Metal Sonic. Offering a temporary truce to help defeat the robo duplicate, Scourge declined. Shortly afterwards, Dr. Eggman dispatched his new metal duplicate, Metal Scourge.

Metal Sonic and Metal Scourge together proved more difficult to defeat for Sonic and Scourge, thus Sonic started helping Scourge out. The Suppression Squad remained watching the battle, unwilling to help Scourge. Eventually however, as the battle began getting worse, The Suppression Squad joins the battle as Scourge's request, resulting in the destruction of the robotic-duplicates. Sonic proceeds back to New Mobotropolis, only to learn he is being sent on a mission of invade Anti Mobius, his punishment being Amy Rose joining him on the mission.

As Sonic and Amy got ready to go into Moebius, Rotor informed them that they will end up in a random location on Moebius. Sonic and Amy wind up in Moebius near Anti Julian's base. Soon, Sonic and Amy found themselves under attack by what seemed to be a giant robot, though the battle was stopped by the kindly Anti Robotnik, who explained the robot was in fact an Omega Care Unit keeping Buns Rabbot alive. After explaining Scourge's invasion of Mobius and their please for help, Buns suggested seeking out Rosy the Rascal as she detested Scourge, though Julian was opposed to this as she was apparently mentally unstable. Meanwhile, Miles from the Suppression Squad was sent to bomb New Mobotropolis. The Freedom Fighters arrive on the scene, only to see that Miles is actually willing to propose an alliance against Scourge. After Miles explains how Scourge took over there world, Sally agree`s on helping him. Despite this, Sonic, Amy and Buns set out to locate Rosy, eventually discovering her in Moebius' version of Castle Acorn. After a brief conversation, Sonic and Amy soon learned how crazy Rosy was when she attacked them.

Buns and Amy fended off Rosy, while Sonic went back to Mobius for assistance. However, the Freedom Fighters and Suppression Squad were too busy fighting off Scourge the Hedgehog. When Sonic tried to stomp Scourge, he was blocked by Fiona. She told him that she stopped trusting everyone around her. Sonic than corrected her, saying she was fighting hard for Scourge. Furious, Fiona started crying and attacking Sonic. Amy then shouted at Sonic to hurry back to Mobius, before Rosy went any more crazier. But before he went back, he ran in another room and punched Scourge. Afterwards, they were both blasted by Boomer and thrown back into Moebius by Miles. Afterwards, Boomer shut down the star posts; therefore, Sonic and Scourge couldn't come back to Mobius. As soon as Sonic got up, he was attacked by Rosy, who stopped Amy and Buns.

The fight is interrupted when Shadow arrives by using Chaos Control. Though he was actually looking for the Special Zone, Sonic asked if he wanted to help him to defeat Scourge, to which he reply's "sure". Metal Sonic arrived shortly after, followed by Silver the Hedgehog and Rob O' the Hedge. The group of hedgehogs then got involved in a massive brawl, including Amy and Rosy. During the battle, Silver became confused because he could not determine which of the hedgehogs was Sonic. After Silver attempted to find out who Sonic was by asking, he eventually found out who it was. He proceeded to attack Sonic but was stopped by Rob O' the Hedge who demanded an explanation. After Silver explained, Sonic proposed a truce for everyone to team up against Scourge. In response, Scourge rushed to the throne room, followed by Sonic and Shadow, turning the tables on everyone by turning into Super Scourge using the Anarchy Beryl in his throne.

Scourge defeated them, leaving them unconscious and Sonic in his hands. When the Knothole Freedom Fighters and the Suppression Squad (minus Rotor and Fiona) arrived, Scourge quickly dispatched them, as the others woke up, Sonic picked himself up, but was quickly attacked by Metal Sonic. Shadow then came and helped Sonic, sending Metal Sonic and himself away to a different zone. Sonic then joined in a dog pile on top of Scourge after Silver tried his psychokinesis on Sally's orders, so they could hold down Scourge long enough for him to lose his super form, but Silver's power failed him and Scourge threw the others off of him. While he seemed to be unbeatable, Sonic eventually realized the Anarchy Beryl would have a different (and negative) effect on Scourge to contrast the positive effect the Chaos Emeralds had on him once the transformation ended. Luring Super Scourge away from the others, Sonic managed to stall for time until Super Scourge de-transformed. As Sonic speculated, the Anarchy Beryl drained him of what energy he had left in his normal form, leaving him vulnerable. Sonic subsequently defeated Scourge and captured him.

While Sonic was taking Scourge to the Zone Cops via the Cosmic Highway, Scourge broke loose and tried to escape, but he and Sonic were then arrested by Zone Cops Zector and Zespio for going through zones during a zone lockdown. The cops then took Sonic and Scourge to see Zonic via a Warp Ring. They arrive in a ruined No Zone and Scourge managed to escape by kicking the others out of the way and attempted to fully destroy the No Zone. Sonic and the Zone Cops then met up with Zonic and together they battle Scourge. During the battle, Zonic explained to Sonic that the Zone Cops had been fighting a villain called Dr. Nega, whom Sonic had previously encountered when he was in Blaze the Cat's world. They quickly captured Scourge thanks to Sonic's skills and Zonic's special Control Collar. Sonic then asked Zonic when he was taking away Eggman as he was not from Mobius Prime, but Zonic explained he wasn't because "Sonic-Prime has to fight a Robotnik, and this one is the best candidate to fill in". Sonic was then brought back home by Zector and he then returned to his parents to talk.

The next day, Sonic took part in the advance against the Egg Dome, along with the rest of the Knothole Freedom Fighters and the Chaotix. First knocking out Dark Legion troops, Sonic distracted Lien-Da and the Dark Egg Legion while the Chaotix flanked them. While the Chaotix attacked, Sonic spin-dashed through Lien-Da's flying pod. He was then attacked by Lien-Da, who whipped him, but was then saved by Antoine. After the Dark Egg Legion withdrew, Sonic was tossed up into the air by Vector, Knuckles, Tails and Bunnie to get on top of the attacking Egg Phoenix. Distracting Eggman and forcing the vehicle to stall, Sonic then jumped off while Charmy, Saffron and Ray planted the Neutralizing Mines on the Egg Phoenix. Ray then carried Sonic to the ground while the Egg Phoenix crashed. Sonic attempted to capture Eggman from the wreckage, but Eggman escaped in a hover pod. Sonic hoped to continue the attack, but Sally said that was enough for the day, and they would finish the battle tomorrow.
