Yup. There's this:
Megaman Joins The Brawl!
Here's for the confirmed Veterans and confirmed newcomers: http://nintendo.wikia.com/wiki/Super...s._Wii_U_/_3DS
I'm happy that Shadow & Rayman are confirmed. Even I played Rayman GBA, Rayman PSX, Rayman 2, Rayman 3 Hoodlum Havoc, Rayman Raving Rabbids and several more Rayman games...All the only character I'm gonna wait for is Silver The Hedgehog. If ONLY if there is a fan demand for it. Plus I wanted all the characters from Brawl & Melee to be confirmed to this game.
