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.

Recently, Sonic got caught off-guard and imprisoned by Dr. Eggman, allowing the Doctor to conquer the majority of Sonic's world. Eventually 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, the Doctor simply vanished.

Fallout
Some time after, 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 anxiety 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.

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 dauntlessness in the face of danger.

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.

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 and Rolling Combo, though the latter requires the aid of his friend Tails.

Miles "Tails" Prower
Miles "Tails" Prower is Sonic's best friend and they are as close as brothers. Tails is one of the first allies Sonic made and they have stuck together ever since. While Tails tends to get annoyed by Sonic's recklessness and smugness, it does not put a damper on their bond. Also, when Tails worries about Sonic's well-being, Sonic is quick to offer him emotional support and assure him that everything will be fine.

Tangle the Lemur
Sonic and Tangle the Lemur have been described as "kindred spirits" due to having similar traits to each other.
