The following are a list of characters that have been featured in the Sonic the Hedgehog series. Note that some may not be listed due to their absence on a Nintendo console.

Sonic and friends are the series' most beloved characters in the franchise. Many of these characters have garnered steady fanbases since their inclusion into the franchise.


Sonic the Hedgehog

Sonic the Hedgehog is the main character of the series and debuted on the game of the same name. He's a blue hedgehog and is generally regarded as one of the most popular video game characters of all time. He's best known for his speed, which overtime seems to have increased. His first appearance alongside Nintendo characters (without bashing Sega) was in Mario & Sonic at the Olympic Games for the Wii, though his appearance in Super Smash Bros. Brawl unarguably made a bigger splash among fans. Sega and Nintendo's partnership with the two aforementioned games, among many others (such as the Triforce arcade system), signifies to a great extent just how far the two companies' relationship have come in comparison to 10 years ago when they were competing for the top spot.

Miles "Tails" Prower

Miles "Tails" Prower is one of Sonic's best partners and has been with the blue blur since Sonic the Hedgehog 2. It wasn't until the third installment would Tails, as he's better known, learned to fly using his two tails. His first appearance on a Nintendo owned console was Sonic Adventure DX: Director's Cut for the GameCube, though perhaps even more surprising was his and the rest of the Sonic gang's appearance in Mario & Sonic at the Olympic Games where he was featured as a playable character.

Knuckles the Echidna is a red colored echidna who first appeared in Sonic the Hedgehog 3. He has a short temper compared to the other protagonists of the series and is named after his large knuckles. His first appearance on a Nintendo owned console was Sonic Adventure DX: Director's Cut for the GameCube. In the games that he's appeared in he commonly helps Sonic find the Chaos Emeralds, and will even occasionally have his own missions. Ever since Rouge the Bat first appeared in a game, the two have had a rivalry, perhaps because of how similar the two of them are. Knuckles along with most of the other Sonic characters all appeared together with the Mario cast for the first time in Mario & Sonic at the Olympic Games.

Amy Rose

Amy Rose is one of the star characters of the series who made her debut on Sonic the Hedgehog CD, though first made her appearance on a Nintendo console with Sonic Adventure DX: Director's Cut for the GameCube (like most of the Sonic characters). She is perhaps best known for her giant mallet, her pink hair and her crush on Sonic, which unfortunately for her is not returned (Sonic simply views her as a friend). She, along with the rest of the Sonic cast, made their surprising debut alongside a Nintendo owned character in Mario & Sonic at the Olympic Games for the Wii (later remade for Nintendo DS).

However, after recovering much of his memory, Shadow ended up assisting Sonic in saving the Earth from the Biolizard. Shadow's somewhat rough past has made him very bitter and cold in current years, and due to this, he is capable of joining the cause of good or evil.
