Main Cast - Who Plays the Companions?

A long train of assistants have helped the Doctor fight evil


Doctor Who wouldn't work as well as it would if it weren't for the companions -- the ordinary folks that travel with the Doctor and share in his adventures. Practically, with the companions present for audience identification, the Doctor is free to be more peculiar and alien; and increasingly the companions have been serving a vital role in helping the Doctor understand himself as he adjusts to becoming the last of the Time Lords.
