He is not from a game just the cartoon series Sonic X. If you are talking about Darkspine Sonic, he is from Sonic and the Secret Rings
Dark sonic is not in the game
I don't think dark Sonic's in a game but dark sonic was shown in sonic x
Yes, it was created during the "Dark Age of Sonic". Another game in the "Dark Age of Sonic" is the worst Sonic game in the world: Sonic '06.
Sonic and the Secret Rings
To get dark sonic you must beat the game with every character in the game S.F.G.X.That unlocks mission mode. Beat mission mode and dark sonic is yours if you have trouble go to the youtube user marjosonic and start at video 9 or 8 [I forgot]
It's Dark Spine Sonic. You have to play through the game and collect the seven world rings.
