DW Monsters: Kaldor Robots

The next story in the series is The Deadly Assassin, which does not have a “monster”, or any aliens other than the Time Lords. In the next story, The Face of Evil, we have a mad computer, but then we come to The Robots of Death. Robots, particularly human-shaped ones, have featured several times on the show, but these remain fondly remembered, at least partly for their Art Deco look. They featured in a 1999 novel, Corpse Marker, by the writer of the original TV story, but it’s really in the audio medium that they have had their greatest success. They have so far appeared in three audios alongside the Doctor, and in two series of their own, one of them reaching eighteen episodes.

DW Monsters: Kastrians

The primary antagonist in The Masque of Mandragora is not only a unique entity, but one that’s more of an abstract threat than something we could stat up; it produces visible effects and controls people, but it doesn’t really qualify as a “monster”. Following that story, though, is The Hand of Fear and Eldrad. Now, Eldrad himself is also unique, in that he’s the last surviving member of his species, the Kastrians, but because we can throw time travel into the mix, that doesn’t mean we could never meet another. Having said that, the Kastrians do not return, or even get much of a mention, elsewhere in the TV series. Indeed, their only other appearance to date is in the audio story Eldrad Must Die! which is, of course, a direct sequel.
