My point in bringing up K. Rool was that he isn't as relevant as should be, and he isn't as iconic as should be either. We already know he isn't relevant, but even when you compare him to other "non-relevant" characters like Star Fox, Fox is still more prominent in Pop Culture. K. Rool is from a popular game, but if you talk K. Rool in a mainstream setting, he's an anomaly. Of course, with Smash, most of the greatly iconic characters are already in, but even when you compare K. Rool to the other big petitions (Lil Mac and Ridley), he isn't nearly as iconic as those two.
I'm just saying: if one of the big three are in SSB4 - hell, if two of the big three are in SSB4, K. Rool won't be one of them.
