Venabili has been assigned the task of protecting Hari Seldon by Chetter Hummin (one of several aliases used by R. Daneel Olivaw) who takes an initial interest in Hari Seldon's psychohistory research. Over the course of Prelude to Foundation and Forward the Foundation she shows an obsessive concern for his safety and earns the nickname "The Tiger Woman" for the ferocity with which she is willing to defend him, and her accuracy, reflexes, and skill (all thought to be superhuman to the point of feline). Despite that, throughout her lifetime protecting Seldon, she was always reluctant to harm opponents in the course of protecting her husband. This is a result of her being bound by the Laws of Robotics.
