So, what if at a certain point into the Super Smash Bros. franchise, Masahiro Sakurai decides to pull the "Game characters only" rule and lets characters from all kinds of pop culture (ranging from TV to movies to comics and whatnot) in Smash? How would that happen? I mean, I could see characters like Goku and Mickey Mouse make their way into Smash (and maybe even characters like James Bond as well). Heck, Pingu would be one hell of a revelation for Smash, even though that would seem unrealistic and very unlikely because of Pingu's niche nature outside of internet memes (though Pingu is still a beloved children's icon in Japan, where he even got a anime produced over there!).
