If Megaman is in, the first Wily theme from Megaman 2 is a shoe in. Hell, there's a good chance that it'll be in regardless. It's that good.
Edit: Actually, I've been thinking about something? Why are percentages being given to Megaman's chances of being in Brawl? What are they based on? The only thing that it can be based on is our own individual conviction. I'm not saying if you believe he'll be in, he will be. I'm saying that there's a very good chance he'll be in, but there's no way of knowing for sure right now. The only thing we can do, for all of our dream fighters, is to keep the faith.
