Well, we can’t just sit here glittering, can we?
They brought the Cybermen back for this? After lying fallow for almost seven years, the silver streaks return with a thud in Gerry Davis’ “Revenge of the Cybermen” (Story Production Code 4D). Gone is the sense of unstoppable menace from their last appearance, in Season Six’s “The Invasion,” much less the existential body horror of the original Cybermen that Davis helped Kit Pedler develop back in “The Tenth Planet.” The story on offer here suffers from the same diffused focus as Davis’ last story, the visually impressive yet narratively cluttered “The Tomb of the Cybermen,” which introduced his seminal contribution to Cyberman lore, the Cybermat. A key component of this story, it is cute, cuddly, and oh so carnivorous.
Following directly on from “Genesis of the Daleks,” this story sees the Doctor, Sarah, and Harry appear back on Space Station Nerva, the Season Twelve leitmotif. Only the current version of Nerva contains quite a few more dead bodies than the one they left way back at the end of “The Ark in Space.” The Doctor surmises from the technology on display that they have arrived thousands of years before their last visit, when the station was used as a cryogenic ark to safeguard humanity against solar flares. They await the arrival of the TARDIS, which is travelling through time (yet remaining static in space) to meet up with them after their Time Lord-imposed sojourn on Skaro. In the interim, they explore the now-familiar hallways, discovering that there are only three humans left from whatever fate befell the space station.
In short order, the viewer learns that one of the survivors, Keller, has orchestrated the deaths as part of an overly-elaborate plan to lure the Cybermen to Nerva Beacon, built to warn passing spacecraft about the presence of Voga, a rogue planetoid captured by Jupiter’s gravity fifty years prior. The bait for the Cybermen turns out to be Voga itself, a planet whose copious gold reserves turned the tide of the Cyberwars some generations in the past. As the Doctor helpfully points out, the non-corrodible metal coats the breathing apparatus of Cybermen, suffocating them, and the combined forces of humanity and the Vogans used “glitter guns” to end the conflict. In the long years since, the Vogans have hidden deep within their wandering planet, in fear of the remnants of the Cyber Fleet.
One faction of Vogans, encountered by Keller during his exploration of the planet, wants to end that threat, so in exchange for gold (of course), Keller somehow contacts the ages-lost Cybermen offering the location of their arch nemesis. The Cybermen (again, somehow) send him a Cybermat with instructions to kill all but four people on the beacon. Meanwhile, the Vogan faction builds a rocket that they will use to destroy Nerva once the last remaining Cybermen are on board. And why do the Cybermen want four humans left alive? Because Cybermen don’t do manual labor, apparently—they want the humans to carry the Cyberbombs (yes, really), complete with trapped explosive harnesses, to the heart of Voga to blow it up.
