Gramm

Gramm was a Cyberman from the planet Mondas who was sent on a mission to find Earth.

Biography
Gramm and another Cyberman called Bremm were sent in a scout craft to find Earth, the lost binary twin of Mondas. 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.

Gramm rescued Bremm from Stahlbaum, 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 was terminated. Gramm described it: "Bremm unit closed."

However, Bremm's memories were transferred to Gramm. The Doctor described it as Bremm becoming a part of Gramm. When Gramm mentally reached out to Bremm to check its memories, a broken piano rendition of Silent Night can be heard instead of words. (AUDIO: The Silver Turk)
