Krystal in Super Smash Bros. Brawl
Krystal made several brief appearances as cameos and collectables in Super Smash Bros. Brawl.
Krystal appears as part of many conversations during the Lylat Cruise hidden cameos. There are pictures of each of her phrases in Brawl Screenshots page and all her audio clips can be found on the equivalent Brawl Audio page. The full resolution cameo images are available here.
Krystal also has her own trophy, as do most Star Fox characters. You can, in fact, download this trophy. The trophy says:
Krystal
A member of the Star Fox team welcomed in Star Fox Adventures after the team met her on planet Sauria when responding to a distress signal. Krystal is capable of telepathy and is a valuable member in combat. After becoming romantically involved with Fox, their relationship gets very rocky in Star Fox Command.
