The Complete Doctor Who Back-Up Tales #2

In the ruins of Goth, the Cybermen hunt for a long-lost arsenal of superweapons, led by the coldly calculating Cyberleader Maxel. But when Cyberman Loktar experiences a haunting dream and a shadowy figure moves unseen through the wreckage, the mission takes a chilling turn—something ancient and unseen is watching, and the planet itself may be alive with secrets.

Cyberleader Maxel returns from the Deathsmiths of Goth to find Junior Cyberleader Loktar gravely ill—his systems failing in ways no known cybernetic malady explains. With the vaults emptied and the crew reeling, Maxel must decide whether to abandon Loktar or risk everything to uncover the source of the mysterious illness.

In the ashes of Goth, Cyberleader Maxel stands alone against the relentless tide of destruction, the last of his kind still breathing. With weapons salvaged from fallen comrades, he readies himself for a final stand against the Apocalypse Device—his defiance a spark in the dying light.

In "Black Legacy (Part 4)," Cyberleader Maxel faces a final, desperate stand against the ultimate weapon, pushing his forces to their limit in a bid to prevent its escape. With the fate of the planet hanging in the balance, Maxel makes a final, self-sacrificing move that ends his reign and the threat he once sought to control.

At U.N.I.T. Skywatch-7, a routine alert over a suspected meteorite landing takes a sharp turn when a returning soldier begins to act unlike himself. As his fellow troops close in, they realize too late that the man they knew has been replaced—by a Zygon.
