Joelle Guthrie is the younger sister of X-men Cannonball and Husk. She lived at her family's farm in Kentucky. When Joelle grew up, she joined an anit-mutant organization named Humanity's Last Stand. This in hopes of people recognizing her specialty, even though she had no mutant-powers. It was sort of a jealous rebellious act against her older brother Cannonbal and sister Page (Husk) whom where both mutants and X-men heroes. After the group attacked her brother and sister she left them and helped the X-Men expose the group.
