Main Characters (Heroes & Anti-Heroes)
Sonic The Hedgehog:

Sonic is the worlds fastest supersonic hedgehog, and values freedom and life by his own rules above everything else. He is kind at heart, but can be short tempered and is quick to throw himself into the middle of trouble without a second thought, remaining steadfast to the end. His personality is a juxtaposition of kindness and ferocity, as on the one hand he does all in his power to snuff out evil, but he also can't look away when somebody else is in trouble.

Sonic hates boredom and being tied down, so much of his time is spent running towards the next danger or adventure.

Miles "Tails" Prower The Fox:

Don't let his docile appearance deceive you. This cute twin-tailed fox is an absolute mecha-maniac with skills rivalling those of Dr. Destreggman. Humble about his abilities, he always does his best to help out Sonic, who sees him as something of a cute kid brother. "Tails" can spin his tails like a rotor blade enabling him to fly.

Knuckles The Echidna:

An egotistical dread locked Echidna from the Angel Island, and appointed guardian of the Master Emerald. Sonic may be a drifter, but Knuckles' home is firmly fixed in the mountains. Wild, tough, stubborn and inflexible, Knuckles sees himself as Sonic's rival, perhaps because of his own dreams of a free lifestyle. He's also known as a treasure hunter, and possesses martial arts skills.

Amy Rose the Hedgehog:

An overly cheerful and a slightly erratic girl that poor Sonic just can't seem to shake off. Amy uses her natural initiative and positive attitude to pull the team together, and her weapon of choice, the Piko Piko Hammer, helps her to maintain authority. Despiteher clearly defined goal to one day marry Sonic, he treats her as little more than an annoyance. In his heart he probably doesn't dislike her that much.

Shadow The Hedgehog:

Created by the renowned scientist Professor Gerald at the peak of his career, this black hedgehog is the dark incarnation of Sonic, matching him in both speed and abilities. Shadow never ages, and can use a technique known as "Chaos Control" to distort time and space using the Chaos Emeralds. Since his fall at Colony Arc (Sonic Adventure 2: Battle) he was presumed dead, but has since been discovered by Rouge, alive and in suspended animation at Dr. Destreggman's (Eggman at the time) base. He now suffers from amnesia and has no memory of events prior to his release.

Rouge the Bat:

Rouge is a professional treasure hunter, forever in search of the world's most precious stones, and part time government spy. Fearless, bewitching, and overflowing with feminine charm, Rouge is dedicated to her work, and never leaves a task empty handed. Her external appearance suggests a careless character, but she is actually calculating and manipulative, basing her actions on potential gain rather than abstract morality or manners. Her powerful wings enable her to fly with ease.

E-123 Omega-R:

The last and most powerful of Dr. Destreggman's (Eggman at that time) E-Series robots. Decommissioned and left imprisoned at the base, Omega was reactivated by mistake as Rouge released Shadow. From that point, Omega decided to destroy all of Dr. Destreggman's machinery to take revenge for his imprisonment, and to prove once and for all that he is the strongest. Then soon after he left Shadow and Rouge he had broken down, soon after many G.U.N. agents found his body he was using and did many experiments to bring him back but they failed. After G.U.N. had made a replacement body for him he had broken loose and used a body already and made a cameo appearance in a Season One episode then later appeared to become E-123 Omega-R. Then he travelled with Sonic, Tails and Amy.

Recurring Characters
Cream The Rabbit & Cheese The Chao:

A cute little rabbit that takes her tiny Chao "Cheese" with her wherever she goes, and at just 7 years old, is even younger than Tails. Brought up like a princess, she is a little naive and simple minded at times, often getting herself wrapped up in other people's problems. She also loves ice cream. She never forgets her manners, and even offers a polite curtsey before attacking Dr. Destreggman, with extreme prejudice. By flapping her huge ears, Cream can sustain flight.

Main Characters: (Villians)
Dr. Sliman:

From the orders of Kronos, Dr. Sliman has to kill Sonic to achieve world domination, but as Dr. Sliman fails the first time, he seeks to get revenge on Sonic and his friends after foiling his first plan. Yet each time he fails to succeed his world domination plans. But with the help of many villians he might succeed such as Kronos the master of darkness who is the only one who can destroy Sonic! Dr. Sliman originally came from another unknown universe which is yet to be revealed. He is also a mad scientist out to create monsters and creatures to destroy his enemies which isn't only Sonic but many of Sonic's enemies such as Dr. Destreggman and Metal Bros. He is also unable to age as Kronos had put a spell on him so he has more of a chance to get Sonic.

Kronos:

The most villainous enemy of Sonic's who is too powerful to be reckoned with. He is the same age as the Earth and has been defeated by many heroes throughout time but somehow he keeps on returning to dominate the world. But as Sonic has entered his life he has found it difficult to dominate the world and uses Dr. Sliman to destroy Sonic so he has one problem out of the way.

Dr. Destreggman (Formally known as Eggman) :

As his name implies, Dr. Destreggman is a Doctor that looks like an egg. As well as having an unfeasibly high IQ of 300, Destreggman is a romanticist, a feminist and a self-processed gentleman. Sadly, his charms are often difficult to spot through the abominable laughter that accompanies his maniacal declarations of world domination. Sonic is always finding ways to stop his diabolical plots, but as with all great arch-enemies Destreggman now sees Sonic as more of a rival than a threat.

Metal Bros.:

The two robot twins who were originally created by the reknowned scientist Dr. Sliman but as they had turned against him and tried to kill him they had gone solo to try and get Sonic and kill. But there are many times where Sonic and the Metal Bros. have to work together to defeat Dr. Sliman but they are rivals and there have also been many times where Sonic has defeated the Metal Bros. because they have plans to take over the world.
