Sonic the Hedgehog (IDW)

Sonic the Hedgehog is the titular protagonist of the Sonic the Hedgehog comic series published by IDW Publishing. An anthropomorphic hedgehog endowed with super speed, Sonic is renowned as the hero of his world, which he fiercely defends from evil, primarily in the form of the villainous Dr. Eggman and his henchmen.

Appearance
Sonic is a thin anthropomorphic hedgehog with blue fur that covers most of his body, peach skin that covers his arms, muzzle and front torso, and emerald-green eyes. He has six long quills on the back of his head, two spines protruding from his back behind his shoulders, and a short tail.

For attire, Sonic wears two light-weight, hyper friction resistant red sneakers with white cuffs around the ankles, gray soles, and white straps across the top, the last of which are held down by a golden buckle on each foot. He also wears a pair of white gloves with sock-like cuffs on his hands.

Past
Sonic has spent years of his life battling his arch-nemesis, Dr. Eggman and his forces for the fate of the world, with Sonic always prevailing in the end. Along the way, he has made numerous friends, rivals, and other enemies, such as his best friend Tails, whom Sonic practically raised. Some of Eggman's plots that Sonic has foiled include Eggman's countless attempts to procure the Chaos Emeralds, and the deployment of the Death Egg,

Perhaps the earliest known conflict between Sonic and Eggman included a battle between the two where Eggman was in his Egg Viper mech, which ended in Sonic's victory.

Another encounter involved the Space Colony ARK, in which Eggman used its Eclipse Cannon to blow up a part of the moon in order to show the world the power that he wielded. These events lead to Sonic, Eggman and their allies eventually teaming up to stop a bigger threat.

Later, Sonic, Tails and Knuckles formed a team. Soon after, a battle happened between Team Sonic and Neo Metal Sonic - the powered up form of Metal Sonic - who was impersonating Eggman. This time, the fake Eggman was piloting the Egg Emperor mech, but Sonic and his friends defeated the mech. After learning that Neo Metal Sonic had taken over the Eggman Empire however, Sonic and his team defeated the robot, causing him to revert back to normal.

After that, Sonic took part in war against the Black Arms when the vicious aliens invaded; with the aid of Eggman's forces, Sonic and his allies were able to repel the Black Arms. Some time after, Sonic foiled Eggman's plans when the doctor shattered the planet with the Chaos Energy Cannon.

At one point, Sonic saved Planet Wisp when Dr. Eggman tried to conquer it. Along the way, he befriended the Wisps, the alien inhabitants of Planet Wisp, including a White Wisp named Yacker. Soon after, Eggman tried using the power of a monster known as the Time Eater to mess with time until Sonic stopped him. During this incident, Sonic fought the Egg Dragoon and won. Not long after, Sonic and Eggman would duke it out on the Lost Hex, with Sonic emerging victorious. While there, the Wisps assisted Sonic.

The War
Recently, Sonic got caught off-guard and was imprisoned by Dr. Eggman in a cell in space, allowing the latter to conquer the majority of Sonic's world. After six months of imprisonment, though, Sonic was freed by the Resistance, a freedom fighting group formed by Sonic's friends and allies, whom he joined up with. Participating in the Resistance's war efforts, Sonic fought a Metal Sonic phantom at one point during the war.

After many battles, Sonic and the Resistance were able to break the Eggman Empire's control over the world. At the climax of their war, Sonic fought Eggman, who was armed with his Death Egg Robot. After Sonic beat Eggman however, the Doctor simply vanished. In aftermath, Sonic left the Resistance, who began focusing on cleaning up after the Eggman Empire.

Fallout
About a month later, Sonic noticed a local town under attack from a Badnik force. He quickly rushed to their aid, helping trash many of the robots. He soon came across some Egg Hammers though, who were able to put the pressure on the hedgehog. Fortunately, Sonic's best friend Tails was able to step in and help him destroy the Badniks. Afterward, Tails confided in Sonic that the Badniks had been undergoing much more coordinated attacks following Eggman's absence. Realizing there could be something controlling them, Sonic thought it might be Eggman, but Tails did not believe so, as Eggman was known for making sure they knew he had returned before attacking. Regardless, Sonic remained determined to take care of the rest of the Badniks like he always had, but Tails expressed his worry over the thought of Sonic losing again. Sonic thus promised Tails to be careful and even offered him to tag along with him. However, Tails decided it was more important to help the town that they had just saved rebuild and recover. Commending Tails for his decision, Sonic set off on his new quest alone.

At the neighboring town, Sonic brought down the Death Crab down before it could cause any major damage. Amy Rose then arrived and helped finish the Death Crab off. She explained that she heard about Sonic and Tails' latest actions and came by to find Sonic to present him with a request: rejoin the Resistance. The Resistance had their hands full as there were many leftover Badniks from the last major battle against Eggman who randomly attacked citizens. However, much to Amy's dismay, Sonic declined her offer as he wanted to find out who was controlling the Badniks on his own.

Sonic and Amy soon discovered that the Death Crab was just a decoy so that more Badniks could invade from the west. While Sonic thinned them out, Amy rallied Wispon-wielding villagers to help destroy the Badniks that reached the town square. Sonic and Amy then continued to destroy more Badniks and find their source. During this time, Amy kept asking Sonic to join the Resistance. Soon, Sonic and Amy discovered a Blowfish Transporter unloading many more Badniks at the edge of the town. With her Croquette Bomber technique, the duo took out the Blowfish Transporter. Afterwards, Amy came to terms with Sonic's decision and let him be on his own. Regardless, she requested for him to check on Knuckles the Echidna in a nearby town as she had not heard from him since. Accepting the mission, Sonic set off to find Knuckles.

As he arrived at the next town, which was a hub for Wispon distribution, Sonic found that Knuckles had already dealt with the Badniks that had been attacking the town. Knuckles explained that the town's Wispon shipments had dwindled and he had come to find out why. The two entered the town and found its citizens in a panic. They were told that all the town's Wispons had been stolen by a duo of mercenaries that had, before the war ended, driven Eggman's forces away and saved the town, only to then conquer the town and keep its arsenal to themselves. With this in mind, Sonic and Knuckles continued to the town's supply depot-turned-fortress to defeat the mercenaries. There, they encountered a group of captive Wisps being horded. Soon, Sonic and Knuckles confronted the mercenaries, who introduced themselves as Rough and Tumble. A battle ensued between the four, which seemed to be evenly matched until Sonic called upon the help of the Wisps that were trapped within the Wispons Rough and Tumble had stolen. They broke out of the Wispons and allowed Sonic and Knuckles to easily defeat Rough and Tumble, who were promptly arrested and hauled off to jail. With the town now free, Sonic and Knuckles began partying with the townspeople.

Continuing his journey, Sonic arrived at the next town, where a Buzz Bomber battleship was deploying by a stream of Badniks to attack the town. As he entered the town, he reconsidered Amy's invitation to rejoin the Resistance, but pushed that aside. He soon after noticed a ring-tailed lemur fightin the Badniks as well, who introduced herself to him as Tangle the Lemur. Together, they fought the Badniks until they got cornered by a large group of them. Fortunately, Blaze the Cat appeared, and helped them tear through the rest of the Badniks' ranks, including the giant Buzz Bomber. Once the attack had ended, Sonic introduced Blaze and Tangle to each other, and asked Blaze what brought her to his world. She explained she had come to prevent a "terrible event" on his world, as per the Sol Emeralds' directions. Sonic thought she referred to Eggman's global takeover until Tangle brought up the possibility that the organized Badniks could a sign of something worse coming their way, which made Blaze stay until she understood why she was here. After bidding farewell to Blaze and Tangle, who went to calm the fires in town, Sonic continued his search for the Badniks' ringleader.

The Fate of Dr. Eggman
Soon, Sonic got contacted by the Chaotix, who needed his help. Meeting up with his escort Espio, the two heroes were forced to clear out some Badniks attacking them. After that, Sonic was filled in on the Chaotix Detective Agency's activities by Espio, who told him that they had found Eggman, and that he was taking him to him. Arriving in a village, Sonic was introduced to a friendly Dr. Eggman, now going by the name "Mr. Tinker", but scoffed the Doctor's greeting. Learning from the Chaotix that Eggman seemingly suffered from amnesia, and had become a productive member of the village, Sonic began talking with the Chaotix and the village's head about what to do with Eggman since it did not seem right to penalize him now that he was a good man with no recollection of his evil deeds. However, a horde of Badniks soon approached the village. Suspecting Eggman to be behind them, Sonic confronted him while the Chaotix faced the Badniks, only to find a scared Eggman protecting the local children. Convinced now that Eggman was a new man, Sonic helped the Chaotix beat the Badniks. Telling the Chaotix about Eggman, the group decided to leave him to his new life. After properly greeting Eggman, Sonic prepared to leave, but then noticed Eggman mention Eggman Land. Immediately after, Shadow and Rouge showed, with the latter seeking to destroy Eggman.

Although Sonic tried telling Shadow that Eggman's amnesia was legit and that he was now a good man that did not deserve the punishment Shadow had planned, Shadow did not care. Eventually, their disagreement came to blows. While they raced around and fought however, Sonic convinced Shadow that Eggman was not beyond forgiveness, just like Shadow was in spite of his past attempt to destroy the world. However, when Shadow realized that Sonic had been leading him away from Eggman, the back hedgehog went back to the village, forcing Sonic to hurry back. Fortunately, by the time Sonic arrived, Eggman had convinced Shadow that he was not the person he used to be by showing him that the "Eggman Land" he mentioned earlier was but an amusement part for children which he had named after a word that "came to him". After Shadow and Rouge took their leave, Sonic promised Eggman that he would come back to visit, if only to check if the doctor's memories were returning.

Eventually, Sonic joined up with Tails again, whom he began raiding bases with in search of clues to whom was commandeering the Badniks. While flying through the sky in the Tornado however, the duo encountered an Egg Fleet battlecrusier. Seeing this as an chance to get a noteworthy clue, Tails had Sonic board the battlecruiser so he could get some computer data. On the crusier, Sonic met someone who looked like Eggman. Since Sonic had seen Eggman however, he did not buy the bluff, and the faker revealed himself to be Neo Metal Sonic. In addition to being the ringleader behind the Badnik attacks, Neo Metal Sonic revealed that, using Eggman's bio-data, he had taken control of the Eggman Empire and that he was currently trying to conquer the world for Eggman, whose whereabouts he intended to get from Sonic, with an unknown plan. Sonic tried to defeat Neo Metal Sonic, but was forced to flee after the robot copied his bio-data. Destroying the ship's Badnik staff and artillery along the way, Sonic ultimately escaped Neo Metal Sonic with Tails and the Tornado's aid. Rendezvousing at Resistance HQ, Sonic told Tails, Amy and Knuckles of what he had learned. In an effort to undermine Neo Metal Sonic's scheme, Sonic and co. decided to search for any old plans that could tell them what Neo Metal Sonic was up to.

Soon after, Sonic infiltrated one of Eggman's bases. There, he encountered Silver when the psychic hedgehog destroyed a Spina for him. The two of them then noticed that the "Guardian Angel" was in the area when she sniped a Spina sneaking up on them. With Sonic oblivious to who that was, Silver told him about her and her efforts during the war. Silver then explained that he had come back from his time to help Sonic and co. stop Neo's plans, which would lead to the extinction of all life in his time. The duo soon after found the Guardian Angel. Although Silver scared her into the shadows, Sonic convinced her to trust them when her Wisps playfully greeted him. With the Guardian Angel, who introduced herself as Whisper, on their side, Sonic and co. broke into the base's computer room. There, they overcame E-107 Theta and a horde of Spinas. After keeping Whisper from destroying the computer, Sonic had Silver access the Eggnet. On it, they discovered Neo Metal Sonic's horrific plans, which prompted Sonic and Silver to contact Knuckles and Amy at Resistance HQ and have them call everyone in.

The Battle for Angel Island
Afterward, Sonic returned to Resistance HQ. There, Sonic and the Resistance's other allies were informed of what he and Silver had discovered: that Neo Metal Sonic had conquered Angel Island, which he had turned into a flying fortress, and secured the Master Emerald for himself on the island. As Amy laid out a plan on how they could liberate Angel Island, Blaze offered to confront Neo Metal Sonic as Burning Blaze, which Sonic was all about. However, Tails shot down that plan, having deemed it too risky if Blaze had to face Neo Metal Sonic's powers. In the end, Sonic and Knuckles were chosen to confront Neo Metal Sonic instead and secure the Master Emerald while the others focused on breaking the [Egg Fleet's control over the island.

On their way to Angel Island in one of the Resistance's battleships, Sonic thanked Whisper for joining them on this mission before paying Tails a visit in the captain's nest. As the two friends were having a moment however, the Egg Fleet began bombarding the ship. Using their Extreme Gears, Sonic and Knuckles left the crashing ship and flew to the Master Emerald's shrine, which had been turned into a fortification. Inside it, the two heroes found Neo Metal Sonic on top of the Master Emerald. When they tried to confront him however, Neo Metal Sonic used the Master Emerald to turn into Super Neo Metal Sonic. While Sonic was undeterred, Super Neo Metal Sonic went on the offensive. Sonic subsequently tried to distract Super Neo Metal Sonic while Knuckles went for the Master Emerald, but both him and Knuckles were foiled and outfought at every turn by the robot. When Sonic and Knuckles ended up lying in defeat before Super Neo Metal Sonic however, Shadow showed up and succeeded in making Super Neo Metal Sonic revert back to normal before laying the smackdown on him. Sonic brought the fight to a halt though, concerned that Neo Metal Sonic would copy Shadow's powers. However, Neo Metal Sonic revealed that he had just finished copying Shadow's biodata, which, combined with Sonic's biodata and the Master Emerald's power, would let him assume his final form. While Knuckles and Shadow tried in vain to stop Neo Metal Sonic, Sonic convinced them to evacuate the stronghold once the structure started to fold into Neo Metal Sonic. The ground soon after began to rumble and Knuckles noted that the Master Emerald had been cut off from Angel Island―without its power, the island would fall. Meanwhile, Neo Metal Sonic grew into a form more monstrous than the last―dubbing it Master Overlord―and demanded that Sonic bowed to him.

Personality
Always prepared to put his life on the line to protect others, be they friends or civilians, Sonic is a carefree spirit and a fearless daredevil at heart with a strong sense of justice, who, unlike most, finds fun in fighting and thwarting evil, primarily in the form of Dr. Eggman and his empire. Despite his usual egotistical and sometimes lazy demeanor, Sonic's defining traits have always been his pure heart of gold and his utter dauntlessness in the face of danger.

Owning to his free-spirited way of life, Sonic values freedom above all else and strives to live his life according to his own rules rather than the standards of those around him or for the sake of heroism and duty. As such, despite his loyalty to his friends and allies, Sonic is typically unwilling to commit to anything that requires him to act primarily under the authority of others, including his friends, believing that he knows what is best for himself.

Powers and abilities
Sonic's trademark ability is his super speed. He can travel up to speeds surpassing Mach 1, which is at the blistering speed of about 768 mph, and he utilizes this in hand-to-hand combat, giving him quick reflexes and reaction time. He is also very agile, being capable of performing extreme acrobatic feats. 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, run over water, plow straight through foes, and build up enough momentum to throw spears with such speed that they can pierce large metal structures while exerting enough air pressure to blow said structures apart. Sonic can also use the Boost to not only increase his speed but also barge through obstacles in his path.

Sonic also has incredible jumping skills: he can set off with enough power to bend thick metal armor and go hundreds of meters into the air with a single jump. He is also incredibly dutrable as well, being capable of taking a hit from an artillery shell and emerge from it without a scratch.

Sonic has demonstrated complete mastery of his speed at any level. Not only can he run at a maximum tilt in straight lines, but also through sharp turns with full control over his momentum, and without recklessly crashing into unintended targets. As far as stamina goes, Sonic's is seemingly limitless as he is never winded from running.

Sonic also possess the ability to harness the power of the Chaos Emeralds. With them, Sonic can give himself a boost in power.

Sonic's core offensive maneuver is the Spin Attack, a technique where he curls into a concussive ball or cutting disk and directs himself at his targets. With it, Sonic can shred or burrow through just about any substance given enough speed, and perform moves like the Spin Dash, Homing Attack, and Rolling Combo, though the last one requires the aid of his friend Tails.

Super Sonic
By absorbing the seven Chaos Emeralds, Sonic can transform into Super Sonic. While in this state, Sonic's natural talents are increased exponentially.

Dr. Eggman
Sonic and Dr. Eggman have spent years as archenemies, due to the latter's constant attempts at planetary domination, which Sonic always thwarts, causing him to become a thorn in Eggman's side. The two have battled for the fate of the world under various circumstances, from Eggman's imprisonment of various types of wildlife to the planet's surface being shattered by the Chaos Energy Cannon.

Recently, in an unexpected turn of events, Eggman managed to catch Sonic off-guard and imprison him, allowing him to easily conquer most of the world, though his reign ended when the Resistance freed Sonic and helped him defeat Eggman six months later. When Sonic and Eggman next met, the latter had taken up residence in an idyllic village and was seemingly amnesiac, having no recollection of his past life. Initially, Sonic was left conflicted and doubtful about Eggman's amnesia being genuine, but later decided to restart his relationship with the doctor on friendlier terms after witnessing him in fear from an attack by his own Badniks, which Sonic and the Chaotix stopped.

Miles "Tails" Prower
Miles "Tails" Prower is Sonic’s oldest and closest friend, to the point that the two can be considered surrogate brothers. Tails is likewise considered Sonic's personal wingman and partner in their various adventures.

The pair have demonstrated near-perfect synchronization in battle whenever paired up, with Tails always being prepared to give Sonic a lift using his flight ability or both combining their Spin Attack to form the Rolling Combo. Also, whenever Tails worries for Sonic's well-being, Sonic is quick to give his buddy emotional support and assures him that he will be fine, even offering Tails to join him "just like old times."

Amy Rose
Amy Rose is Sonic's longtime admirer and one of his closest friends, and the only one who’s known to harbor deeper feelings toward him, feelings that she never tries to hide around him, which often makes him uneasy. While Sonic cares very much for Amy however, he does not returns her romantic feelings. Nonetheless, he has a good relationship with her, and with most of his friends, she can be subject to his jokes and teasing.

Knuckles the Echidna
Knuckles the Echidna is both a close friend and rival to Sonic, with the two of them being no stranger to butting heads over a disagreement at worst, or partaking in banter with each other at best. Due to their rivalry, they tend to occasionally try and outdo each other. Despite this, the two put a lot of trust in one another's abilities and work near perfectly to get the job done.

Silver the Hedgehog
Sonic are good friends and allies with Silver the Hedgehog. While Silver's awkwardness at times clashes with Sonic's more level-headed and cool-headed demeanor (which prompts Sonic to tease Silver), they are nonetheless faithful allies who put a lot of trust in one another. They also work well together in combat.

Tangle the Lemur
Sonic and Tangle the Lemur have been described as "kindred spirits" due to having similar traits to each other, particularly their skill and enjoyment in battling Badniks, as well as the confidence they share in doing so.
