You can't unlock Shadow in brawl, only Sonic. Shadow is only an assist trophy.
To unlock the assit trophy of Shadow you unlock Sonic. You can not use Shadow as a playable character.
Shadow is only unlockable as an assist trophy in Brawl. He is unlocked as an assist trophy when you unlock Sonic as a player.
In super smash brothers brawl you cannot unlock shadow. You can only unlock sonic.But you can unlock him in an assist trophy
You can't... at the moment, Shadow is merely an assist trophy.
