In Doctor Who the Doctor usually travels with one or two regular companions. Doctor Who companions are generally human and more often than not, female. Most of the main companions stay for a series or two and then something happens and they move on or get left.
But the Doctor also encounters other people on his journeys. Often one will take up the role of a companion, just for an episode, joining the regular crew. These folks can be nobodies or Charles Dickens. These five are particularly memorable.
5. Adelaide Brooks, The Waters of Mars
Adelaide Brooks was the smart, brave no-nonsense leader of Bowie Base One on Mars. At the time she met the Doctor she was a grandmother and a very experienced astronaut. Initially distrustful, she came to believe the Doctor’s claims about her and her crew being a fixed point in time. That events couldn’t be changed without disastrous consequences.
However, the Doctor himself decided to take matters into his own hands. He tried to save the crew, and Adelaide. However, in the end, while he succeeded in getting Adelaide and two others back to earth, she took matters into her own hand. She ensured that her granddaughter would be inspired to become the great astronaut history would remember her as.
