Professor Powers was an elderly woman who was the only person who cared about Tobias after the assumed death of his parents. She gave Tobias food and told him stories. Professor Powers lived on a hilltop house that looked like a lighthouse overlooking the ocean on the opposite coast to the Animorphs Hometown. She had a raspberry bush in her garden. Professor Powers made Tobias hot cider and homemade cinnamon rolls. Her kitchen was painted yellow and blue. When at Professor Powers' house, Tobias felt he was at home.
Professor Powers had greying hair and kind eyes. Her voice was strong and deep.
