The Vanquishers (TV story)

, prefixed in the title sequence with Chapter Six and in other sources with Flux, was the sixth episode of series 13 of Doctor Who. It formed the sixth and final chapter of the six-part serial Doctor Who: Flux.

It brought an end to the storylines of Swarm and Azure and saw Inston-Vee Vinder finally reunited with his pregnant wife Bel after they spent most of the season looking for one another.

It was the first televised story to see the Doctor coming face to face with the embodiment of Time, although such a thing had previously been presented in the Virgin New Adventures novels.

The episode gave a similar ominous warning of impending doom for the Thirteenth Doctor as had been previously given to the Tenth Doctor in the 2009 special Planet of the Dead.

Synopsis
Having taken control of Divison's base in the Void, and of the precious fob watch containing the memories stolen from the Doctor by Tecteun, Swarm and Azure stand poised to achieve their ultimate revenge. Meanwhile, the Sontarans, working in conjunction with the Grand Serpent, have taken Earth once again as part of a gleeful scheme to exploit the Flux to become the dominant species in the cosmos once and for all, surpassing even the Daleks and the Cybermen. With the help of Joseph Williamson and his tunnels through time, the Doctor's stranded companions must unite to vanquish the ultimate threats to life in the universe.
