Will somebody please tell us what it all means?
Just when you thought it was safe for the Doctor and his companions to visit an isolated human outpost that coincidentally contains a device capable of destroying the Earth, the Cybermen show up yet again to spoil the day. In almost every regard, Kit Pedler’s “The Moonbase” (Story Production Code HH) reads as a remake of his “The Tenth Planet,” aired a scant four months earlier, only with a different Cyberman weakness and a different Doctor at the helm, plus a groggy Scotsman who thinks a Cyberman is an avenging angel. We have: a remote international base (on the Moon instead of the South Pole); a commanding officer who effectively shrugs his shoulders at strangers knocking on his door; a doomed Earth spaceship; a group of Cybermen knocked out by quick companion thinking; a whole bunch of technobabble that sets up the doomsday device on the base; and a Cyberman weakness that requires humans to act in their stead and lets the Doctor turn the tables on the silver suited cyborgs.
And yet, derivative as it is, “The Moonbase” winds up being very different from “The Tenth Planet” almost entirely because it’s the Second Doctor rather than the First doing the table-turning.
If nothing else, “The Moonbase” represents the moment where Patrick Troughton’s Second Doctor finally comes into his own as a fully developed character, out from William Hartnell’s shadow. To be sure, Pedler makes the connection between the two Doctors, with the Cybermen recognizing the Doctor (and vice versa):
Cyberman: You are known to us.
Doctor: And you to me.
The Daleks in “The Power of the Daleks” similarly recognized the Second Doctor, suggesting, again, that the Cybermen know of him from encounters between the original 1986 meeting, where the First Doctor regenerated, and their current 2070 engagement. But there, we didn’t recognize the Doctor even if the Daleks did; here, we feel like we know this Doctor: he’s crafty, cautious, and cunning, aware of his limitations and confident despite that knowledge. By the this story ends, we know how the Second Doctor thinks and acts. Pedler simply nails it. We almost feel badly for the Cybermen, because we know this is going to end poorly for them. You might say the Doctor blows them off their feet.
