That right there is Alesia Glidewell. She provides the voice of Krystal, the female "companion" to Fox McCloud in the StarFox series. If you follow a link to her official website, you can find a list of voice work she has done. In that list it states that she recorded the voice of Krystal for Brawl. She also did the voice work for two other Brawl characters,Knuckle Joe from Kirby & Zero Suit Samus from Metroid. Of course, the most interesting mention is Krystal considering we haven't seen her on the Dojo yet.

The website does seem to be Ms. Glidewell's actual page. The only question now is, will Krystal appear as a playable character, assist trophy, or something else altogether? Huge thanks to Trike, Internutt, and Hashmeer for the heads up!
