Who the Doctor is
The Doctor is an alien Time Lord originating from the planet Gallifrey. He journeys in the TARDIS, a spacecraft whose name stands for Time And Relative Dimension In Space, which can travel to different times and locations across the universe.
Role and purpose of companions
- Companions serve as fellow travelers who share the Doctor’s adventures, often helping to resolve crises and protect others.
- They commonly act as an audience surrogate: by learning about unfamiliar situations at the same pace as viewers, they provide a natural way for the Doctor to explain plot details and concepts.
- Across the series, companions have various narrative functions — from moral anchors and emotional supports to investigators and active participants in action sequences.
Origins and types
Most companions have been human beings from Earth, frequently drawn from the time period in which an episode was produced so contemporary viewers could relate to them. The show has also featured companions from other species and non‑human entities; on several occasions the travelling party has included robots or alien allies.
How companions are presented in reference works
When companions are catalogued in guides or episode lists, they are typically grouped beneath the incarnation of the Doctor they travelled with and ordered by their first appearance in the television series. This provides a chronological framework for following the changing line‑up of companions across the programme’s history.
