Recurring and Historical Characters
The Daleks are a race of mutants encased in powerful cyborg bodies whose shape is reminiscent of pepperpots. The Doctor first encountered them on their home planet of Skaro in The Daleks (Classic Series Season 1). In that story, they were confined to a single city on Skaro and the Doctor thought he had defeated them forever. He later encountered them in The Dalek Invasion of Earth (Classic Series Season 2), where they had conquered the planet Earth, and The Chase (Classic Series Season 3), when they had acquired a time travel machine and were chasing the TARDIS through time and space. In both instances, he managed to defeat them.
The following stories and other resources are not necessary in order to follow the plot (we've summed up the essential bits for you). But being familiar with them will probably enhance your enjoyment of this story.
None, unless you want to revisit the Daleks' past appearances.
