Personally I can't imagine what kind of attacks could Pac-man have, even Sonic's attacks are very similars, thats the reason why I don´t like to see Pac-man in Smash, my other reason is the fact that is that introducing new 3 party characters is hard not only because the licences, even because if for example Sakurai want another character from another company probably Sakurai will tolerate the company that probably want their character is well represented, enogh to be chosen for many players, and the player if the newcamer is overpowered
