Johan Drossel

Dr  was the person who bought two Cybermen from a forester. He liked the sound of his voice and had a predilection to theatrical effects.

At first he collaborated with Alfred Stahlbaum, until the latter stole one of the Cybermen, whom he dabbed The Silver Turk, to perform at the Vienna Exposition.

He fell under the influence of Cyberethics and became obsessed with the idea of creating a new world where people are replaced with wooden puppet copies. This obsession caused him to replace vital parts of his body with Cyberinlays.

Having told the second Cyberman, whom he called his dog, that his companion is dead, Drossel ordered him to make wooden puppets that could move without strings and obeyed Drossel's commands, including Columbinetta, Brighella and Pierrot. With his puppets, on 11 September 1873, he organized his own performance at the Vienna Exposition, which he vainly called Doctor Drossel's Grand Theatre of Puppetry.

Under Drossel's instructions, his dog also made puppet copies of several people, sometimes using the eyes dug from a graveyard and sometimes, for better likeness, using the eyes of the prototype. Drossel's dog also made puppet black horses using blue human eyes for them. These horses were sometimes seen around Vienna driving a cab without a cabman, scaring people.

In order to return the Silver Turk, Drossel used his dog to hunt and kill Dieter Wallmann and Leopold Krauss, two of Stahlbaum's patrons. When his first attempt to murder another patron, Count Rolf Wittenmeier, failed, he ordered his puppets to abduct the Count's wife, Countess Mitzi Wittenmeier. But the puppets by mistake took the Doctor's companion Mary Shelley instead.

After his dog, having learned about the Silver Turk, abandoned him, Drossel murdered Count Wittenmeier and moved the Marionettenburg from the Exposition to Count Wittenmeier's house. The puppets continued producing new puppets even in the absence of his dog.

Using his puppets he abducted Stahlbaum, Mary and the Doctor. When Stahlbaum told Drossel that he believed both his dog and the Silver Turk had died struck by lightning, Drossel tried to persuade Stahlbaum to work with him again, but in vain.

When his dog returned, Drossel has learned his true identity as a Cyberman from Mondas named Gramm and realised that he can speak and that he and not Drossel controls all the puppets. At first, Drossel tried to be useful, but then rebelled and killed Gramm. However, without Gramm, all cybertechnology, including inlays in Drossel's body stopped functioning, causing his own death on 12 September 1873.

The Doctor destroyed the inlays leaving the rest of Drossel's remains for the police. (AUDIO: The Silver Turk)
