At an E3 developer roundtable, director Masahiro Sakurai revealed that Pac-Man will be a playable character in Super Smash Bros. for Wii U and Super Smash Bros for 3DS.
Pac-Man will appear in his 3D version, but will transform into his original, 2D self for some attacks. According to a Tweet from Nintendo, his powers include throwing fruit and eating power pellets.
