Zephon
Oh, great. Another member of the Galactic Council that conspired with the Daleks for universal domination. Like so many other council members, Zephon is an example of rather lax naming conventions. Zephon came from the planet Zephon. Zephon had a child, whose name was also Zephon.
The Doctor robs the Daleks, gains two companions, loses three, and then we even get an appearance by the monk. Epic!
Three astronauts who aren’t The Doctor battle homicidal vegetables and Daleks while the latter plot to take over the galaxy.
