Sonic the Hedgehog (SML)

Early Life
Sonic was born on day 162 of the year 3220 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. Sonic eventually had his name legally changed, with no disrespect meant to his forebears.

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 of Knothole Village under the protection of Rosie and Julayla.

Sonic and his friends returned to Mobotropolis at the end of the Great War. Both of Sonic's parents had fallen victim to the Roboticizer, his father during the Great War and his mother after its end, forcing his Uncle Chuck to raise him alone. Sonic and his friends were present on the day Miles "Tails" Prower was born, and Sonic was sure they would grow up to be great friends. Later that same day, 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. Sonic himself was tasked with locating as many children as he could find and bring them to the haven of Knothole by Colonel Tig Stripe, which he successfully did. While in Knothole, Sonic and Sally became inspired by Tig Stripe's band of Freedom Fighters, eventually forming their own group called the Knothole Freedom Fighters with their friends Rotor Walrus, Antoine D'Coolette and young Miles "Tails" Prower. Together they promised to overthrow Robotnik and take back their city.

Freedom Fighter
Over the years, Sonic and the others struck back against Robotnik's growing empire. Using guerrilla tactics and espionage to ruin many of Robotnik's schemes, Sonic's speed proved to be a crucial element to the team's success. By the age of eight, Sonic was easily defeating Robotnik's Badnik hordes, including the Super Special Sonic Search and Smash Squad. One of Sonic's earliest missions had him investigating one of Robotnik's slave labor camps; there, he met a young Mighty the Armadillo and Ray the Flying Squirrel, who had both been imprisoned. Sonic eventually freed Mighty and the two attempted to free as many prisoners as possible, forcing Robotnik to abandon the camp. However, Ray was seemingly lost and Sonic and Mighty failed to save a young girl named Fiona Fox. Sonic and Rotor also found and rescued a girl named Bunnie as she was being roboticized; though the process had been half-completed, she resolved to join the team. As time went on, Robotnik began to see the Knothole Freedom Fighters as a viable threat, and thus made it his priority to locate their secret village of Knothole.

While most of his time was spent combating Robotnik and his hordes of SWATbots and Badniks, Sonic occasionally encountered other obstacles. 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 alternate self, Evil Sonic. Although he quickly defeated his evil double and safely made his way home, he had made a longtime enemy.

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 island's 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 teamed up with Sonic and Tails and the three retook the Emerald from Robotnik.

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

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 was 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 eventually caused Metal Sonic to overheat, destroying the robot's legs and causing him to crash. The rest of the Freedom Fighters went on to free Amy and Tails, who had also been captured.

Mecha Sonic
Feeling the need to step up their efforts, Sonic proposed a plan 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 an enhanced robotic body. The plan was denied by Sally and the Knothole Council for being too risky, much to Sonic's dismay. However, Sonic was later captured by the bounty hunter Nack the Weasel, who turned the hedgehog over to Robotnik; thus he was roboticized without the Neuro-Overrider. 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 the village, he was unable to transmit the coordinates of its location, as he was engaged in combat with Bunnie Rabbot and later Knuckles the Echidna, who had arrived in response to a distress call. While Mecha Sonic managed to overcome his former allies, it was then proposed that Knuckles be roboticized in order to better match Mecha Sonic's abilities. The fight between Mecha Knuckles and Mecha Sonic concluded with the two crashing into a nuclear stockpile in Robotropolis. Mecha Sonic, badly damaged and having regained some of his free will, felt deep remorse over his actions, and Mecha Knuckles returned him to Knothole. Sonic was restored to his former self when Sally used the magical powers of Sonic's one billionth Power Ring, healing and deroboticizing him at once.

However, Sonic was tried in court by Antoine for treason, as it was believed that Sonic had disobeyed the council and had allowed himself to be roboticized; though Sonic was ultimately found guilty, he was given the opportunity to prove his innocence. Eventually, he succeeded in hunting down Nack the Weasel, clearing his name.

Endgame
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 trick Hershey the Cat into seemingly murdering Princess Sally while framing Sonic for the act. 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. Sonic was arrested for the murder and sentenced to the Devil's Gulag; however, by chance, his transport was shot down and he escaped, resolving to clear his name and find those responsible for killing Sally. He was forced to evade Geoffrey St. John, who relentlessly tracked the hedgehog, and eventually found himself cornered on the Floating Island by Knuckles the Echidna and Espio the Chameleon; however, thanks to Dulcy the Dragon, who possessed the ability to detect lies, he was able to finally prove his innocence. He returned to Knothole (which at this point had been overtaken by Robotnik's forces) with Geoffrey and Knuckles to liberate the citizens. During it all, he discovered Drago and Hershey's involvement in framing him and set off for Robotropolis. Once there, Sonic and Robotnik engaged in hand-to-hand combat. Due to Snively's treachery, however, the Ultimate Annihilator was reprogrammed to only target the war room and Robotnik's DNA signature, erasing him from existence, thus finishing the battle and ending the ten-year reign of the evil dictator.

A New Age
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 discovered his parents were still alive when he met them for the first time since his early childhood years. In order spare Sonic the truth of is parents' existence as Robians, Chuck had told Sonic they had died during the Great War. Angered by the deceit, Sonic was unwilling to speak to either his uncle or his parents for some time.

With the real King Max returned to power (although still suffering from the crystallization effects that resulted from his time in the Zone of Silence), it seemed Mobotropolis would regain its peaceful state. However, the king first ordered that the Freedom Fighters be disbanded and, when concerns arose between the Robians and the rest of the population, he decreed the former were to be dismantled. As conflict arose from these decrees and tensions continued to mount, it was eventually 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. Sonic used the Sword of Acorns to free the king from the wizard's control. 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 loose 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 Great Desert 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 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 made their way into space. Once inside the massive station, which was formed by the connected satellites, Sonic and his friends discovered a horrifying secret -- Doctor Robotnik was still alive!

Return of Robo-Robotnik/Rise of Eggman
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 they'd been lured into space so that Robo-Robotnik's Shadowbots could easily reclaim Mobotropolis and capture its citizens for roboticization. Additionally, all the other Robians had been transported to the station and had their free will removed, once again making them Robotnik's workforce. With his second takeover of Mobotropolis in effect, Robo-Robotnik soon sent the Robians off -- but Sonic's parents remained to assist their son, having retained their free will thanks to their power ring wedding bands. Sonic and the Freedom Fighters were able to destroy the satellite base with the help of Snively, and escaped on the space shuttle, with Sonic's parents, back to Mobius. Robo-Robotnik, seemingly left to perish, 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 Robo-Robotnik now in control of Robotropolis, the Mobians fled to Knothole Village. In his new body, Robotnik renamed himself Dr. Eggman, and planned on downloading the location of Knothole Village into his mind from his old systems. However, before he was able to do so, Sally, NICOLE and Snively (who was forced to tag along at the time) deleted the information from Robotropolis' computers, preventing Knothole's 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. One girl attempted to run back into the city, desperate to find her family, but Sonic stopped and comforted her; this girl introduced herself as Mina Mongoose. With the help of Dulcy the Dragon, Sonic, Sally and the other refugees made their way back to Knothole.

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 alongside Tikal. The humans in Station Square thanked the Freedom Fighters for their help.

Before they could return to Knothole, however, Dr. Eggman launched another mechanical duplicate of Sonic, known as Silver Sonic II, to destroy Station Square. 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, as Nate Morgan had reprogrammed Silver Sonic II to protect 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 reconnaissance of the area, Tails was captured and taken hostage by the metallic duplicate, who wished to prove his superiority over Sonic. Sonic, determined to rescue his best 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. Sonic managed to temporarily trap the robot and left to rescue Tails from within Mount Mobius, which was about to erupt. Metal Sonic soon caught up and taunted the two; while Sonic argued that the capability for compassion was not a weakness, Metal Sonic continued to boast that he was superior to organic lifeforms. However, when Metal Sonic saw that Tails and Sonic were willing to risk their own safety for the sake of the other, the robot had a change of heart. Moved by their selflessness, Metal Sonic held back the lava flow and told them to escape; when Tails insisted on saving him as well, he argued that it would only doom them all. His last words were to remind them to think of him as an unfeeling robot. Forced to leave, Sonic later told Tails that while his words seemed to have no effect on the robot, it was Tails' refusal to abandon the hedgehog that caused Metal Sonic to understand the meaning of those words. The two decided it was time to head home.

Dr. Eggman and Other Foes
Upon returning home, Sonic found King Max amassing an army in order to rescue Prince Elias Acorn from Dr. Eggman. Distraught from the turn of events, Sally was forced to stay in Knothole and tasked Sonic with keeping her father safe. During the fight, however, Sonic saw the king use the Sword of Acorns to unintentionally restore free will to his uncle Chuck and Muttski. This distracted Sonic, and King Max was soundly struck by a ShadowBot. While the mission was a success overall, Sonic's failure to protect Max resulted in the king being wheelchair-bound for many months. Sonic felt guilty over this; however, he nonetheless stole the Sword of Acorns, planning to use it to restore the free will of the remaining Robians in Robotropolis. He ran into Mina Mongoose on the way, who had also lost a parent to roboticization; the two were suddenly attacked by Combots, and Sonic was knocked unconscious. While Mina was able to get Sonic back to Knothole, the sword was lost.

Later, while attempting to retrieve the sword from Dr. Eggman (unaware that it had since been taken by Uma Arachnis), Sonic witnessed the return of the Overlanders from space. Feeling they were in danger from Robotnik as much as anyone, Sonic attempted to convince them to flee the area; however, an enraged Monkey Khan soon arrived, seeking revenge from Robotnik, and the Overlanders were spooked by the two Mobians. This allowed Robotnik to easily convince them to seek "safety" within his city, which they did. Having failed here, Sonic returned to Knothole; having lost the Sword of Acorns, he was stripped of his knighthood and ordered to remain confined within the village.

Weeks later, Sonic went against orders once again and left the city, wanting to check up on the Overlanders in Robotropolis. He was joined by Bunnie Rabbot, and the two were shocked to find that Eggman had not harmed the people. Within the Great Forest, the two were caught up in a battle between Uma Arachnis and Kodos. As Kodos proved to be extremely wild and dangerous, Sonic forced Bunnie to leave; however, Sonic soon found himself about to be killed. To his surprise, Uma Arachnis viciously attacked Kodos and freed Sonic before departing. Sonic secretly left Kodos at the hospital in Knothole before returning home. The next morning, a Shadowbot charged into Knothole; as it turned out, Uncle Chuck had indeed regained his free will and had reprogrammed the robot in order to deliver a message to Sonic; Uma had taken the Sword of Acorns. Adopting a disguise and going by the alias, "The Sneak" of Sand Blast City, Sonic attempted to track down Arachnis; however, when Geoffry St. John and the Royal Secret Service went to Robotropolis, thinking the Sword of Acorns was still there, Sonic stepped in to rescue them, only for them all to end up temporarily captured. Once free, he attempted to get back to Knothole before he could be recognized, hiding his disguise in the woods.

Just as Sonic stashed his disguise, he was apprehended by Station Square's defense force G.U.N.; they believed that Sonic was responsible for the recent destruction of Silver Sonic II and the theft of a Chaos Emerald. It turned out that the real thief was Shadow the Hedgehog, a being created by Dr. Robotnik's maternal grandfather Professor Gerald Robotnik. Sonic eventually found Shadow on Prison Island on a mission to steal the six Chaos Emeralds. As the two fought, Eggman informed Shadow that he had set the charges on the island and it was set to blow. Shadow's partner, Rouge the Bat, then called saying that she was trapped in the vault where the other Chaos Emeralds they sought were held. Eggman, unconcerned, merely told Shadow to meet him later, saying that they'd simply dig out the Emeralds once the island had blown up. Sonic, overhearing this, offered a temporary truce with Shadow in order to save Rouge. The two managed to reach Rouge within the vault, and Shadow used Chaos Control to teleport all three out into a desert near Eggman's base. He then teleported away with the Chaos Emeralds. Sonic and Rouge, after introducing themselves, formed an alliance; Rouge was actually an agent of G.U.N. sent to investigate Shadow and Eggman's actions, and the two broke into Eggman's base to steal a shuttle in order to reach the space station known as the ARK. As it turned out, the ARK was armed with the dangerous Eclipse Cannon, which required Chaos Emeralds to fire. Sonic confronted Shadow again, and as they battled, Rouge found a video that she felt Shadow needed to see. Realizing his desire to use the Eclipse Cannon in revenge against Mobius was folly, Shadow teamed up with Sonic and the two attempted to shut down the cannon. However, a monstrous prototype called the Biolizard used Chaos Control in an attempt to cause the ARK to crash into Mobius. However, the two hedgehogs used the emeralds to transform into Super Sonic and Super Shadow and defeated the beast and then used Chaos Control to send the ARK back into orbit; unfortunately, Shadow had exhausted himself during the battle, and Sonic could only watch as he fell toward the planet's surface.

Eventually returning home, Sonic began training Mina Mongoose to use her recently-discovered super speed. One day, Kodos awoke within the hospital and went on an insane rampage; it was discovered that he had suffered extreme radiation poisoning from living within the sewers of Robotropolis. When Sally found the near-dead Uma Arachnis, the spider revealed to the princess where she'd hidden the Sword of Acorns; this resulted in Sally being chased by Kodos, who, in his insanity, had become obsessed with the Sword. Sonic thought that Sally had fallen to her death within a ravine; however, she was saved by the power of the Sword of Acorns, which had been hidden there, and used it to vanquish Kodos. Thanks to Kodos, it was realized that the Overlanders in Robotropolis were also being exposed to toxic radiation; the Freedom Fighters set out to warn them. Eventually the Overlanders were convinced to leave; thanks to the Sword of Acorns, the Robians of the city were also freed.

Sonic was later called back to Station Square to save them from Zan the Dragon, in exchange for allowing the Overlander refugees to relocate there. Further problems included the temporary return of Dr. Robotnik, who attempted to betray the Freedom Fighters to Eggman before perishing for good. He also helped free the Walrus Herd from Eggman's control, protected Knothole from a nuclear strike launched against Robotropolis by O.T.I.S., fought the Arachne to protect the Sword of Acorns, helped Zonic after he was attacked by Evil Sonic, persuaded Uncle Chuck of his innocence for actions he had taken while under Eggman's control, and battled Mammoth Mogul after learning that the villain had replaced Tails with a magical duplicate. Sonic would then deal with a genie who gave Muttski his speed, join Bunnie and Rouge the Bat in stopping Eggman from creating a new and more dangerous robotic body, reunite with his old friend Tommy Turtle before losing him again, be Roboticized by the Bem alongside Tails to battle a De-Roboticized Eggman and Snively, thwart a new model of Caterkiller, stop Eggman from capturing Elias, defeat Nack the Weasel's gang to save Sally, and admit his feelings for her. This resolved her previous fears that he was more attracted to Mina Mongoose, whom he helped start a singing career.

Xorda Attack and Tossed in Space
Sadly, just after Sally and Sonic announced their engagement, 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'Novulans to assist Sonic's trip home. The D'novulans 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 Breeblebrox 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.

Return to Mobius
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 a 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.

Fighting the Eggman Empire
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.

Switcheroo
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.
