Bill Potts, played by Pearl Mackie, was working as a dinner lady when she met the Twelfth Doctor, who was teaching at St. Luke's University. Although she wasn't a student, Bill would attend his lectures. She became his companion after she discovered that he was a time-travelling alien and he invited her to join him in the TARDIS. Bill was killed by the Cybermen, but her sentience survived in an artificial form. Bill and the Doctor are shown from the story 'The Doctor Falls'. Both figurines are slightly over 9.5 cm tall.
