Overview
This season featured the return of several elements from the show's history, such as the Brigadier, the Master and Omega. This season also technically featured the return of both the Daleks and the Cybermen in the 20th Anniversary Special, though their roles are basically insignificant, and they are both overshadowed by a man in spandex and a fencing mask. This season also debuted the first robotic companion since K9, Kamelion, but his prop was so horrific and difficult to operate that he was quickly dropped.
