They're all still there, they just don't pop up as much anymore. If you want to see the old Sonic characters google it or play "Mario and Sonic at The Olympic Games" they're all in that game.

Not All the Characters but a Few...
You can find Sonic characters at Wikipedia and Google.
go to the address below when you get on the page, scroll half way down and you should see SONIC BATTLE M.E with all the sonic characters appearing . its a full mugen game, but if you just want the characters then open the folder named "CHARS" . all the sonic characters will be there. http://mugencharacters.ucoz.com/
SEGA is the game company who created sonic and all of the characters
yes
Sonic:18 years old. Tails:10 years old. Dr Eggman:43 years old. Amy:12 years old. Blaze:15 years old. Shadow:23 years old. Choas:2 years old. Vector:42 years old. All together in numbers, all character's ages combined are over 100 years old.
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.
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.
