Roberta Tovey (in-universe)

Roberta Tovey was a child actress who portrayed Susan in Dr. Who and the Daleks, a 2065 film which starred Peter Cushing as Dr. Who and was loosely based on the events of the Thal-Dalek battle. (PROSE: Peaceful Thals Ambushed!)

Behind the scenes
A very different in-universe version of Roberta Tovey also appeared in various Doctor Who parody comics by Tim Quinn and Dicky Howett. Rather than an actor, this Roberta Tovey was a dangerous villain, cited by the Sixth Doctor in the same breath as the Daleks and Cybermen among the most fearsome foes he'd defeated.
