Doctor Who: Every Regeneration Ranked From Worst To Best

14. The Third Doctor (Planet Of The Spiders)

Left stranded on Earth due to the actions of his former self, most of the Third Doctor's adventures take place on our home planet, alongside UNIT. They also feature a bright yellow car called Bessie, and Jon Pertwee doing a lot of karate.

Yeah, this was a weird time for the show.

Eventually, Pertwee's Doctor gets his TARDIS back, but this proves to be his ultimate undoing. He travels to a planet inhabited by giant spiders, and destroys them all using the energy of a special crystal. Unfortunately, he too is caught in the blast, triggering his regeneration.

Unfortunately though, his actual final scene takes place under much less dramatic circumstances.

The Doctor manages to pilot the TARDIS back to Earth, collapsing in his laboratory with Sarah Jane and the Brigadier present. They then receive a visit from the Doctor's former mentor, who sort of looks like Lakitu from Mario Kart.

The mentor guides the humans through the process, before fading away as Pertwee's face changes into Tom Baker's.

It's hardly the most exciting regeneration in history, and the presence of a bloke floating on a cloud only complicates things further. The showrunners should have known better by this point.
