I agree with most of what was just said, except Krystal.
1) She could use the staff, regardless of whether Fox is now in possession of it or not.
2) She would have a completely unique moveset with said staff.
3) It doesn't matter if Fox has the staff, or even if Sakurai decided not to give her the staff for the game. Olimar's moveset wasn't part of his game. I'm sure Sakurai has imagination enough to design a new moveset for Krystal. And that's if Sakurai decided not to give Krystal the staff in the first place.
