Sonic the Hedgehog (IDW)

Sonic the Hedgehog is the main and titular protagonist of the Sonic the Hedgehog comic series published by IDW Publishing. An anthropomorphic hedgehog gifted with super speed, Sonic uses his abilities to protect the world from anyone who poses a threat, namely Dr. Eggman.

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 emerging victorious. Along the way, he has met many friends, rivals, and other enemies. Over time, Sonic has gone up against Eggman and his various mechs, such as the Egg Viper, Egg Emperor and Egg Dragoon.

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. Later on, he traveled to the Lost Hex, where the Wisps assisted him on his adventure there.

Recently, Sonic got caught off-guard and imprisoned by Dr. Eggman, allowing the Doctor 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. Together with them, Sonic was able to break the Eggman Empire's control over the world. At the climax of this conflict, 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.

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 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. He is also very agile, being capable of performing extreme acrobatic feats. He 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. 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, and plow straight through foes. Sonic can also use the Boost to not only increase his speed but also barge through obstacles in his path.

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'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.

Miles "Tails" Prower
Miles "Tails" Prower is Sonic’s oldest and closest friend, to the point that the two can be considered surrogate brothers. 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. Despite this, the two put a lot of trust in one another's abilities and work near perfectly to get the job done.

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.
