Morbi
Scavenger
I say quite the opposite.
Sakurai's statements clearly dictate that he was in fact working on alternate costumes who were different characters, an Doctor Mario is not even a separate Character by anything other than title (literal) alone.
It is my personal belief, continuing on, that Lucina was added simply to appease fans of Roy, while maintaining the roster with actual relevant AND recent IPs, as well as having another female on the roster. I believe it is only for these two reasons that Lucina was upgraded to playable status, and Dr Mario being added would only be for the IP, which a costume serves the purpose of just fine.
Not according to Sakurai's statements or precedent (Super Smash Brothers Melee and Lucina herself). Feel free to adhere to confirmation bias, however. It is certainly not fallacious to do so in the least!Dr Mario is a costume. Period.
It sure is quite the opposite if you misconstrue EVERYTHING he asserts.
"... the characteristics of their attacks differ. When two such similar characters function in an even slightly different manner, I give them a separate spot on the roster since that will affect battle records and whatnot."
