Smash Champion
Courtesy of a new Japanese video for Super Smash Bros. Brawl, we get confirmation that Ness of Earthbound fame will be making his way back into Brawl. Not only that, but popular character Jigglypuff from Pokemon will be making a return to the field of combat as well. Oh, and the fun doesn't stop there as Lucario, from Pokemon Diamond & Pearl, also gets confirmed as a playable character. We just hope that the inclusion of Lucario doesn't mean that Mewtwo is getting the axe.
