Well I am going through SSE for the first time and I have just got into the fight againt Meta Knight and Lucario. Am I supposed to play as Meta Knight to unlock Lucario? But then if so will Sonic still challenge me after I am through with SSE? Also after I am done and I am to get Wolf next do I have to go through the WHOLE thing again or do I just pick the level that I am supposed to go to? Thanks, Vail.
