you cant but you can play as super shadow by beating every level.
you cant sonic the hedgehog doesn't have super sonic
You can't. Shadow is the only playable character, and in the final boss when you play as Super Shadow, there is no companion character.
You play as Shadow when you finished Crisis City as Sonic. Shadow's Episode will then be availible to play. You can also play as Silver the Hedgehog when you defeat him for the first time.
You have to complete silver's,sonic's and shadow's story to unlock the last story. When you finally meet up with Solaris, you go SUPER SONIC ! And if you get all S,s on all the missions, then you get free mode where you can play as any character and play them on any level.
NO!
There is no shadow the only characters from sonic the hedgehog is sonic
You can't :3 You can play as Sonic the Hedgehog and Blaze the Cat, but no other characters are playable.
Yes, I think.
For The Last Boss.
sonic 6 only last boss
It depends, if you mean the 06 version, then yes. But if you are talking about the original Sonic the Hedgehog from 1991, then no. The idea of super Sonic wasn't thought of until Sonic 2.
Go to any stage where sonic is your partner, get a second controller and have fun!
