I know, right?

All we have from Sonic in Brawl was GHZ, music, Shadow (assist trophy), various other characters (Knux, Tails and Silver in background of GHZ, and several other characters including them as Trophies), and Sonic himself (playable). In the Adventure Mode, he was at the end!

I understand that he was a sort of last-minute decision. That's why I hope they do good with him this next time around.
