Bremm

Bremm, known on Earth as the Silver Turk, was a Cyberman from the planet Mondas who was sent on a mission to find Earth.

Biography
Bremm and another Cyberman called Gramm were sent in a scout craft to find Earth, the lost binary twin of Mondas. Bremm was responsible for navigation. They were the first Cybermen to succeed in this task. Their craft crash-landed in the mountains of Austria around 1873, badly damaging both Cybermen.

They were found by a forester who sold them to Dr Johan Drossel. The latter invited Alfred Stahlbaum, a talented mechanic, to help him repair these strange mechanical men, but Stahlbaum soon stole Bremm for himself.

Stahlbaum used ether to keep Bremm under permanent sedation. After teaching it to play several musical instruments, including piano, flute and spinet, and several games, including chess and chequers, Stahlbaum organised its performances as "the Silver Turk" at the 1873 Vienna Exposition. The last performance took place at 5 o'clock on 11 September 1873 and was interrupted by the Doctor. Intent on eliminating the Cyberman menace, the Doctor tried questioning Bremm, but the Cyberman managed to mentally knock the Doctor unconscious. Stahlbaum then fled with Bremm before the Doctor came to.

The next day Bremm was rescued from Stahlbaum by Gramm, who also kidnapped the Doctor's companion Mary Shelley. Mary suggested a way to repair their damage using Galvanic lightning. To achieve that, Gramm carried Bremm to the top of Stephansdom, the highest building in Vienna. Although Mary's plan worked, after the lightning struck Bremm only reached "two-five" percent capability. It then proposed to adapt the neural generation unit in its head into a transmitter to contact Cyber-Control on Mondas. After Gramm agreed and removed Bremm's remaining Cyberman arm, Bremm died. Gramm described it: "Bremm unit closed."

Physical appearance
After the crash, Gramm took one of Bremm's arms. Apart from its arm, Bremm also lost both of its legs. The Eighth Doctor believed that its legs had been cut off by Drossel to prevent an escape, but Drossel himself claimed that this had been the result of the crash. Instead of the missing arm, Bremm was given a fully functional wooden arm, similar in appearance to the limbs of puppets from Marionettenburg created by Gramm for Drossel.

Using both arms, Bremm could play the piano and perform other tasks. Moreover, despite not having legs, it was able to work the pedals on the piano.

During the Silver Turk performances, Bremm's face was concealed by an elegant mask with splendid mustachios.

Mission to find Earth
As the navigator of the mission, Bremm should be credited with finding Earth. However, the damage caused by the crash caused both Bremm and his crewmate to believe they were on Mondas instead of Earth. When Bremm learned the truth from Gramm, it still could not verify it and proposed to sacrifice itself to contact Cyber-Control and complete the mission. (AUDIO: The Silver Turk)
