they needed a villan in the series and wolf is the obviouse choice, the mario series has bowser, the zelda series has gannon, the kirby series has dedede (and metaknight i guess). Just look at the events list:
single event 38: Wolf on a Fox hunt, where you are Wolf angainst Fox and Falco.
co-op event 19: Andross' shadow, where you are Fox and Falco against Wolf.
they only put him in for matchups like these, and if they had Krystal, they would have 4 reprisentatives of the series and lets face it, StarFox doesn't deserve 4 characters like Zelda/mario does. my quetion is: if they already have Fox and Wolf, Why bring Falco back?
Smash needed another female character and Krystal could easily replace Falco in the 2 listed events
