I believe this other character is not exactly another Sonic, possibly one of the characters from this reality who have been affected by Eggman's reign. Also, if this idea is true then there might be more characters still around who have been affected. If Shadow is around in this reality then chances are he's a threat if Sonic was preoccupied before meeting Shadow.
