I don't think Krystal is a worthy character because of her popularity and abilities. Rather her ROLE in the series. She's Fox's love interest a driving point in the plot of the Star Fox games. That's why she is worthy. I don't choose characters based on popularity or if think they'd be a good fighter, I choose them because they are important to the series. That's what matters.
Of course before I decide what characters are worthy of being on a roster I have to decide how many characters a franchise deserves to have. This (to me) is always relative to the amount of characters another franchise already has. A more important franchise is always entitled to more characters than a less important one. However how many more characters one franchise has from another should be equal to how much more important that franchise is. Basically even a lesser franchise will have to have more characters if a greater one continues to add more. The more characters one series has, the more insignificant another series seems that only has one character.
However this does not apply to a series that cannot have more characters due to a relatively low cast. This can and should be compensated by other means if necessary.
So how does one decide if "Franchise A" deserves two, three, or four more characters than "Franchise B"? Well I'm no authority but I can safely say it cannot be decided on fanbase alone. We should all be aware of how ignorant and foolish a fanbase can be. With their insane fan girls and such. No, the importance of a franchise has to do with their history mostly and somewhat how Nintendo themselves sees and handles the series. I'd say only 25% of character decision should be based on popularity.
