Companion

Companion was a somewhat vague term used to describe the Doctor’s closest friends. Such people knew the Doctor’s “secret”: that they were non-human who travelled in time and space in a police box-shaped craft called the TADRIS. The Doctor’s companions often directly saved the Doctor’s lives or provided the Doctor with a perspective that prevented them from abusing their Time Lord powers. On some occasions, they were the proximate reason that the Doctor sacrificed their then-current life and regenerated. On others, they lost their lives in pursuit of the Doctor’s goals.
