Spider-Girl was placed on the Castaways after Spyke died. When Iron Man saw the symbiote, he attacked her but sheconvinced him she was in control and she recognized his voice. After finding out he is Peter Parker, she begins calling him "Dad" and they form a father-daughter relationship.
Her first mission was on a world where a zombie-virus has plagued most of the world. Their mission was to activate the nuke that would wipe out the zombies, but they had to keep the humans safe. It was difficult but Iron Man managed to drop the nuke onto the center of America after the Castaways gathered most of the humans and brought them to space.
