Edward Bradley is a companion of the Planet Skaro Doctor and first appeared in Heart of the Haniad. Ed differs from the Doctor's other companions in that his pessimistic paranoid attitude often causes him to regret ever meeting the Doctor, and he often complains about the situations he has found himself in since they met. Underneath his cynical attitude however, he truly does enjoy his adventures with the Doctor, and he has demonstrated that as well as being frequently stressed out, he can also be rather cunning and independent.
