Too Majestic for Gender
That's not how Fire Emblem characters are picked. It's based on who the currently relevant characters are.until Smash 5 or even the port if a bunch of characters are planned on being added as its pretty clear Female Corrin won't be losing popularity anytime soon).
It's why we got Ike, not Lyn or Hector in Brawl and why we got Robin, not Micaiah or Black Knight in Smash 4.
The only character that goes against this is Marth and that's because he's the original Fire Emblem protagonist.
For Corrin Smash 4 DLC was their only chance.
