Sarah-Jane Smith

The most iconic companion of the Doctor’s, some would say – certainly in Classic Who – Sarah-Jane Smith was an investigative reporter whose cleverness seemed to render her immune from the tribunals of U.N.I.T., since she was rather freely allowed to roam their HQ. Travelling at first with The Third Doctor, she continued her adventures with The Fourth Doctor until she was left in not-quite-Croydon following a run-in with the Mandragora Helix. She’d return to meet The Tenth in School Reunion, of course, and go on to get her own spin-off, The Sarah-Jane Adventures.
