Paige was first named in X-Force (1st series) #32. There was at least one unnamed Guthrie girl in Rom Annual #3, but there's no way of knowing whether it was Paige, Joelle, Elizabeth, or Melody. Husk originally was capable of altering her mass to change into a bird or an insect, but that aspect of her ability has apparently been retconned out. Paige became known as Husk in Generation X #1.
