Sarah Anderson was a Human female and the daughter of Earthforce Captain Leonard Anderson and Lynn Anderson. In December of 2266, Sarah had been having nightmares of a monster chasing her and eating her when it caught her, making her afraid of going to sleep. When her father, Leonard learned of this, he assured her that he would always protect her from the monsters and that it was, as a result, safe to sleep. Leonard would use the promise that he made to his daughter to ram the Victory into the control center of the Shadow Planet Killer, protecting her from the monsters within.
