Hey there. You may want to do this. In the official Smash website, there is a character ballot that you can vote to have which Nintendo you want to see to be playable for Smash 4 as DLC so that the developers themselves of Smash including Sakurai will consider to have in the game. This is a great godsend opportunity for all of us especially to you who happens to like the character Krystal(like I do) and a fan of her to get her included in the roster since obviously the Starfox roster needs more reps(Fox and Falco in there is not enough) and with their new game coming out this year, this helps out even more. The link for the official ballot is cp.nintendo.co.jp/us/ . You need to spread the word out on this here. ^^
