no, he is just an assist trophy
Shadow is not a playable character in SSBB but instead open the trophy cases and shadow might come out. Unlock sonic and you get shadow as an assist trophy.
You can't, shadow is only accessible via an assist trophy, he may be hard to get by the way.
I wish you can play as Shadow The Hedgehog as a playable character in Super Smash Bros. Brawl, that would be really awsome. Although you cannot. You cannot unlock Shadow The Hedgehog nor be a playable character in Super Smash Bros Brawl. Although if you unlock Sonic The Hedgehog (playable), you automatically unlock Shadow The Hedgehog as an assist trophy. Also, you can get a Shadow The Hedgehog trophy if you're lucky to find one on the coin launch game. At least you'll have Shadow on Super Smash Bros. Brawl. (But not as a playable character, sorry!) He is playable with hacks. but most of the time it will be some dumb skin hack instead of a psa but if you use a psa you cant play as regular sonic
you can unlock shadow by a action replay
After unlocking sonic either you can go to coin launcher or the subspace emissary to get the shadow trophy.
Well he isn't really a character but he is a assist trophy when you pick up the item you unlock him though by unlocking Sonic the Hedgehog first then shadow is unlocked by a assist trophy
he is an assist trophy
Amy the Hedgehog is not playable in any Super Smash Bros. game.
