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 . After Bremm was stolen by Alfred Stahlbaum , Gramm thought that Bremm died . For a time , Gramm pretended to serve Drossel , making walking and talking wooden puppets for him . Not suspecting a higher intelligence or even ability to speak , Drossel called Gramm his dog and treated it accordingly . However , when Gramm learned from the Doctor ' s companion Mary Shelley that Bremm was still alive , he immediately left Drossel and managed to rescue Bremm from Stahlbaum on 12 September 1873 . As if thanking Mary for her help in finding Bremm , Gramm kidnapped her . Mary suggested a way to repair their damage using Galvani c lightning . To achieve that , Gramm carried Bremm to the top of Stephansdom , the highest building in Vienna . The plan successfully restored Gramm to " eight - seven " percent capability , but Bremm was still too damaged to function properly . By Bremm ' s suggestion , Gramm took Bremm ' s neural generation unit and arm , terminating Bremm in the process . Bremm ' s memories were also transferred to Gramm . The Eighth Doctor described it as Bremm becoming a part of Gramm . To notify Cyber - Control on Mondas about Earth ' s location , Gramm planned to adapt the neural generation unit into a transmitter and use the Doctor ' s sonic screwdriver as the power source . Using Mary once again , Gramm found the Doctor a prisoner of Johan Drossel in Marionettenburg . The Cyberman easily took over the control of the puppets from Drossel . However , Gramm ' s plans were foiled when first Mary broke the sonic screwdriver eliminating the power source and then Drossel rebelled against his former servant killing them both . Physical appearance . After the crash , Gramm lost both of its legs and took Bremm ' s left arm . 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 . Using its three arms , Gramm could move quite quickly in a scuttling manner . After removing Bremm ' s remaining Cyberman arm , Gramm had four arms . Murders . To return the second Cyberman , Drossel ordered Gramm to murder two of Stahlbaum ' s patrons Dieter Wallmann and Leopold Krauss . Following similar orders , Gramm first attacked and eventually murdered Count Rolf Wittenmeier . Drossel believed that murder was in Gramm ' s very nature . Due to Drossel ' s belief that puppets need real human eyes to have " souls " , Gramm often gouged eyes of its victims , prompting newspaper headlines about " the eyeless murders on the Ringstrasse " . Gramm also obtained eyes by digging graves on cemeteries pointed out by Drossel . Gramm ' s puppets . The wooden puppets made by Gramm for Drossel ' s Marionettenburg contained Cyber - Technology , which was a great cause of concern for the Doctor . Some of the puppets were modelled on real people and could speak simple sentences with their voices . These wooden copies were hard to distinguish from the originals , especially if given the eyes of their prototype . Some puppets were themselves capable of producing more puppets . After Gramm was destroyed by Drossel , the Doctor made sure to burn all the puppets , eliminating all anachronistic Cyber - Technology . Gramm also made two wooden horses that could drive a cab without a driver . These horses were given blue human eyes . Mission to find Earth . The impact of the crash caused both Gramm and his crewmate to believe they were on Mondas instead of Earth . Only when Gramm learned the truth from Mary , did it attempt to contact Cyber - Control and complete the mission , but ultimately failed . ( AUDIO : " The Silver Turk " )
