A couple of you found her already, but it looks like Estelle Ellis, Krystal's original voice actress from Star Fox Adventures, is now ready to announce to the world that she has a Twitter account. Her Twitter handle checks out. I can personally confirm that yes, this is really her account. She introduced it with a fun little custom video featuring animation and the model from the Half Life 2 mod. In it, she teases that she may work on other Krystal-related projects, and also, that Command isn't Canon (oof).

She'll be interacting with people through this account, so feel free to follow her and say hi. I hope to do some projects with her in the future myself.
