The 1st attack would totally be Splash Attack!
i think so
Probably because Nintendo couldn't think of a good moveset tails could have but they have him appear in the green hill stage and he is a unlockable trophy in the vault.
Sonic is the only playable character, but Shadow is a helper. I think Tails is one too.
I think he's a playable character because he might be a bonus character.
Non Playable Character, I think.
He should be already a playable character and if not, do the subspace emissary and complete it not 100% completed but you just need to beat the last boss tabuu. Don't want to do that? Go to group mode and play brawl mode play 100 brawls and he will show up but like i said before i think he's already a playable character.
i Think is dk
I don't think so, since Ridley is not the right size to become a playable character, and also consider the fact Ridley is already a boss in the game.
yes I think he should
You can't unlock Shadow as a playable character in SSBB. He is only an assist trophy. The only way I can think of is you do a texture hack to Sonic to make him look like Shadow.
I think R.O.B. is pretty good.
if you mean by: can you unlock any more secret caracters in brawl? then i dont think so.
