Harriot is an experienced soldier in the Rebel Army, who was tasked by Abigail to capture defectors; in her case, the Professor, Percier and Ariadna. However, she was caught during her mission. Percier, who appeared to recognize/remember her, promised her that if she joined the Martians, she would promise her three meals and nap time. Harriot accepted the deal and began working with the Martians. She affectionately calls Percier "Per". She is rather laid-back and prefers letting others do her.
