Doctor Who: Ranking Every Regeneration From Worst To Best
10. The Fifth Doctor To The Sixth Doctor
Keeping things trippy, 1984's The Caves Of Androzani saw Peter Davison's Fifth Doctor exit the show. Much like Patrick Troughton's regeneration, multiple visages are seen rotating around the dying Doctor's face, with The Master centre, demanding the Doctor dies. Of course, the Doctor regenerates into a new form, and we're given a perfect first impression of this new Doctor.
"Doctor?""You're expecting someone else?""I- I- I-""That's three 'I's in one breath, makes you sound a rather egotistical young lady."
Regeneration can be traumatic for both a Time Lord and their companions, and things weren't great for Peri. Not only was she insulted by a fresh Doctor, he proceeded to strangle her soon after. This didn't bode well for viewers continuing their loyalty to the show, as warming to a new Doctor might take a while. For some, they simply never warmed to Colin Baker's Sixth Doctor.
