The first characters are Sonic the Hedgehog and Doctor Robotnic (later called Dr Egghead), from the very first game, in which Robotnik had trapped animals from the forest in his robot henchmen.
The next character to join the series is Miles "Tails" Prower, in Sonic the Hedgehog 2, in which a second player could control Tails. Metal Sonic also makes his/it's first appearance.
After that Knuckles the Echidna joined in Sonic the Hedgehog 3. He is the protector of Angel Island and the Master Emerald kept there, and he sets off a trap to prevent Sonic's advance in the forest. Eventually he becoms an ally to Sonic.
Some new characters are introduced in Knuckle's Chaotix.
A bunch of new characters appeared in Sonic Adventure on the Dreamcast.
Among them, Chaos is the first one you see ( in the opening sequence). You also meet omochao and the chaos ( not to be confused with Chaos :P) for the first time.
Some new playable characters are available, Big the Cat ( along with him Froggy), Amy Rose and the E-102 Gamma robot. You also meet Tikal the Echidna, a spiritual help to Knuckles.
In Sonic Adventure 2 once again new characters are introduced.
Sonic's rival Shadow the Hedgehog is a biological experiment to produce the ultimate lifeform. He is confused for Sonic in the beginning of the game. His only friend while in the research facility was Maria Robotnik, who rescued him and motivated him to fight for man kind. He was created by Professor Gerald Robotnik in an attempt to cure his granddaughter Maria.
Rouge the Bat is a new playable character who at first glance seems to join Dr. Eggman just for a chance to steal some valuable jewels. She is however working as an undercover agent for the president.
There are some new chaos, like the doctor, psychic, teacher and merchant in the black market. These aren't recurring characters though.
All the Sonic characters are single, aside from Amy as she likes Sonic and Sonic because Amy will most likely kill the girl if he ever got a girlfriend.

SEGA is the game company who created sonic and all of the characters
yes
sonic is better than all the video game characters even halo and sonic is better than any cartoon characters even other new characters that are in videos
I doubt it. Cause they tend to make Sonic characters that they never bring back.
Probably not. Seriously, Dic should make a sonic cartoon with all the characters they used in their cartoons. Scratch and grounder, Snively and Cluck, Sleet and Dingo, Antoine, Captain Rescue, and everyon else. Wouldn't that be the best sonic show ever? (It would certainly be better than sonic x.)
Mario & Sonic at the Olympic Games, Mario & Sonic at the Olympic Winter Games, and Mario & Sonic at the London 2012 Olympic Games do not have unlockable characters. All playable characters are available from the start.
Amy like Sonic thats all i know because there isint enougf proof that other characters like other characters
