Cyber wrist blaster The secondary weapon of the Cybus Cybermen , and later the Cybermen of Mondas , the wrist blaster was a retractable mounted weapon powered by hydrogen gas and was housed within the Cyberman ' s forearm . It consisted of a small segmented steel gun that when about to be used , retracted out of the forearm , extended at the front , then fired a red particle discharge containing an EMP ( electromagnetic pulse ) that could kill a human almost instantly and penetrate clothing . The gun was connected to the Cyberman ' s vision circuits to ensure precision in aim . The wrist guns were seen , but not used during the creation of the first Cybermen . ( TV : " The Age of Steel " ) They were used during the Battle of Canary Wharf , though the guns were completely ineffective against Dalek force fields , leading to many Cyberman casualties during the battle . ( TV : " Doomsday " ) In her partially converted form , Lisa Hallett could fire a blast similar to those of the wrist gun however the laser seemed to come from inside her wrist casing instead of from a mounted weapon . This variant could only stun the part of the body which it hit . ( TV : " Cyberwoman " ) Despite not being able to damage Daleks , the weaponry proved effective against other forms of machinery such as robots ( COMIC : " Drones of Doom " ) and even other Cybermen . ( COMIC : " Time of the Cybermen " , GAME : " Blood of the Cybermen " ) The Cyber - Lord in charge of the Cybermen which had crashed at the GSO Arctic excavation site used a Cyber Wrist Blaster to kill Elizabeth Meadows , though the discharge from this blaster was more yellow than that of the other Cybermen . The Cyber - Lord and two of its guards were also killed by a wrist blaster on a detached Cyber arm used by Chisholm to save the Eleventh Doctor and Amy Pond . ( GAME : " Blood of the Cybermen " ) Not all of the Cybus Industries Cybermen were equipped with one of the weapons . Amy Pond later noted a slight difference in the appearance of the Cybermen with wrist blasters and those without wrist blasters . ( GAME : " The Mazes of Time " ) The wrist blaster was able to be used even if the Cyberman ' s arm was severed as part of the suit ' s assimilation protocol and it could rotate . The Cyberman guarding the Pandorica under Stonehenge used the weapon , but the Cybermen accompanying the Cyber - Leader when the Doctor was imprisoned both carried large handheld energy weapons . ( TV : " The Pandorica Opens " ) The Cybermen of the Cyber Legion s who crashed their ship in 19th century Klimtenburg could have used their wrist blasters against their enemies but the Doctor noted they did not have enough power to use them . Only one Cyberman was able to fire their blaster during the whole incident . ( PROSE : " Plague of the Cybermen " ) The Cybermen which were part of the main forces of the Cyber Legions such as the Ninth Cyber Legion and Twelfth Cyber Legion used Energy blaster s instead . ( TV : " A Good Man Goes to War " , GAME : " The Eternity Clock " ) The Cybermen recovering from the Cyber - Wars under Hedgewick ' s World of Wonders had wrist blasters . The discharge was blue in colour . Alice Ferrin was killed by one of the weapons . ( TV : " Nightmare in Silver " ) The wooden Cyberman sent down to Trenzalore during the Siege had a wrist blaster which doubled as a flame - thrower . The Eleventh Doctor sent a signal with his sonic screwdriver to the device that would have reversed the polarity of the weapon and cause it to fire backwards . The Cyberman turned its weapon around and shot a hole through its own chest , the Doctor neglecting to mention the screwdriver didn ' t work on wood . ( TV : " The Time of the Doctor " ) A trio of Cybermen , including the converted Dr Skarosa , pointed their blasters towards Clara Oswald ready to kill her but hesitated in the case that her claims to be the Doctor were true . They were subsequently destroyed by blaster fire from Danny Pink , who himself had been converted into a Cyberman , before he rescued Clara . Danny later pointed his blaster at Clara when she stated that the Doctor was the best man ever , unknown to her that it was Danny inside the metal man , but hesitated and shakingly lowered it again . The Brigadier , after having been resurrected as a Cyberman , shot with his blaster . ( TV : " Death in Heaven " )
