Oh god I've got Gobi's Valley stuck in my head.
I have no problems with female characters, and some of the characters I play (Lucina and Inkling) or would like in Smash (Byleth and Arle) are females (or in Byleth's case, have a female variant). With that being said, however, what I do have a problem with is a character getting in to meet some sort of quota ("Oh, we need a girl in the Fighters Pass because there's not enought wameens in the game!" or "Muh shooter reps!" "Muh Bamco reps!") To me, that's just straight up
tokenism. (Here's a
Wikipedia article on that.) (For example, let's say that the devs add a Mexican character (T. Hawk, Manny Calavera, etc.) to Smash for the sake of hispanic representation. As I am a Mexican, I'd be pretty offended by that because my ethnicity is being reduced to a character.) None of the male characters fill any quota whatsoever as far as I can tell (or any characters in Smash so far, spare Greninja and Incineroar who are shillmons but hey,
they're fun). I'm not saying that "to have representation" is the only reason to have more female fighters (or any fighters, really), but I am saying that's a sexist (and to be frank, delusional) reason to have them. When it comes to thinking about who we want in Smash, I think we should ignore race, gender, and maybe even genre entirely.
I've got a question, actually. Why does representation matter? Do you really think that Sakurai and the devs were thinking about representation when they chose Dark Samus and/or Isabelle?
Oh, and I still think Arle is likely for #5. Also, I think Byleth would make for a nice moveset.
