Most of the ol' gang in the Geno thread seems to be back. Or at least have posted once
So, if she isn't Fox's girl, doesn't that make her even LESS relevant to Smash?
Since the argument for her is she fits into the archetype Hero, Sidekick, Love Interest, Villain quad thing
That archetype works for non-generational series, although I would argue it's more of an opposite gender hero (which is mostly female) and not necessarily love interest.
Mario: Mario, Luigi, Peach, Bowser
Zelda:Link, Toon Link, Zelda, Ganondorf
You can even stretch it for other series if it's not a love interest.
Pokemon: Pikachu, Pokemon Trainer, Jigglypuff, and Lucario
And for predictions:
Donkey Kong: Donkey Kong, Diddy Kong, Dixie Kong, King K. Rool
Kid Icarus: Pit, Dark Pit, Palutena, Hades (or Medusa)
Starfox: Fox, Falco, Krystal, Wolf
(Doesn't Fit as Well) Fire Emblem: Marth, Ike, Lucina, and Black Knight (maybe)
And for what other series are missing:
Kirby: Does he have a female rep or character?
Metroid: Dark Samus and Ridley fit, but does she have a male hero worth mentioning?
I just did this because I find archetypes fun.
