Go back and complete the stages that have green flags on them. Those are the ones that still have neat trophies and stickers in hidden rooms. Check walkthroughs to find the hidden rooms and make sure you don't get totally killed otherwise you lose everything. I guarantee that if you get everything from the hidden rooms and finish the stage the green flag will be gone and your percentage will go higher. I completed 100% on Subspace Emissary doing that so you need to get 100% for the game to be officially completed.
Sonic will appear during the final battle in the Subspace Emissary
After you beat the subspace emissary, you have to go back to the swamp and there is another door there for you somewhere go to the ruins to obtain wolf, after beating subspace emissary.
You . . . don't. There are only two ways to unlock characters in Brawl: either have them join you in The Subspace Emissary--and there are multiple ways to do this, depending on the character--or fulfill the requirements outside of the Subspace Emissary, like completing Classic mode in a certain time limit, and best the character in a one-one brawl. That's it. If you don't want to go through the Subspace Emissary to unlock characters, you'll have to brawl with them. If you don't want to brawl, go through the Subspace Emissary. There is no third option.
