Only Sonic has been a confirmed playable character.
Espio is playable in Sonic heroes,Knuckles Chaotix,Sonic the fighters,Shadow the hedgehog and Sonic Rivals 2.
As a playable character,no. The character Sonic is there, but is locked. Knuckles appeared as a collectable trophy :)
Yes. Sonic is the only playable character in Sonic the Hedgehog 2 Single Player. The only other single player character you can play as is Knuckles. To play as Knuckles, you need Sonic and Knuckles and attach it to the game card of Sonic the Hedgehog 2.
No he doesn't crack his knuckles. That's just his character name.
Sonic Shadow Silver Knuckles Metal Sonic Amy
There is no red hedgehog in Sonic the Hedgehog. You either mean Knuckles the echidna, the second player Sonic from Colors and several bootleg games, or a sonic fan character. Shadow is a black hedgehog with red markings, but he's probably not who you saw.
Knuckles came from angel island where sonic hedgehog is green hill.
"Kouga" does not exist in the Sonic series and therefore cannot be played in any sonic game.
go to the part in adventure mode where you fight tabuu and wait because sonic will come and then he's a playable character. defeat tabuu and then sonic is playable
Because it's supposed to be Nintendo not Sega.
knuckles is 15,in sonic the hedgehog 3.
You can only get Knuckles in Sonic 2 if you stack Sonic 2 and Sonic and Knuckles on the Genesis. Otherwise Knuckles cannot be played in the game.
