Every Classic Doctor Who Companion Ranked From Worst To Best
1. Sarah-Jane Smith
Sarah-Jane Smith travelled with the Third and Fourth Doctors, though she encountered the Fifth, Tenth and Eleventh Doctors as well. Young, bubbly and infectiously upbeat, she would serve as something of a template for the most popular companion of them all, with many who followed attempting to fit the mould she made.
She was present on Skaro for the birth of the Daleks, something that shocked Davros when they encountered each other again at the Medusa Cascade. Fiesty and trustworthy, the Doctor went so far as to introduce her to people as his best friend when the situation arose, an honour rarely bestowed on these early companions.
She was one of the most confident and headstrong companions to travel in the TARDIS, keeping this spirit alive once she was returned to Earth by the Doctor, albeit an entire country away. She continued to investigate the strange and the startling and, though it took quite a while, her path did cross with the Doctor's again as they both investigated the Krillotane incident.
She was one of the last people to see the Tenth Doctor before his regeneration, sharing a silent but tearful smile with her old friend. Sadly, Elisabeth Sladen passed away not long after this, though she was able to film an episode with Matt Smith before her death.
