They were conceived by writer Kit Pedler (who was also the unofficial scientific advisor to the series) and story editor Gerry Davis, and first appeared in the 1966 Doctor Who serial The Tenth Planet.Pedler, influenced by the logic-driven Treens from the Dan Dare comic strip, originally envisaged the Cybermen as "space monks", but was persuaded by Davis to concentrate on his fears about the direction of spare-part surgery.The Cybermen of The Tenth Planet still have human hands, and their facial structures are visible beneath the masks they wear,[5] but over time they evolved into metallic, more fully mechanized designs.A Cybermen scouting party is sent to Earth in search of the legendary Nemesis statue, a Time Lord artefact of immense power, made of the "living metal" validium[check spelling].They appear again in "A Good Man Goes to War" (2011), when the Eleventh Doctor's (Matt Smith) companion Rory Williams (Arthur Darvill) demands the location of a secret asteroid base in a quadrant of space which they monitor in the 52nd century.In "Closing Time", an ancient slumbering cyber ship is awakened in 2011 Colchester, and the Doctor and his friend Craig Owens (James Corden) work together to repel a Cyberman invasion.These redesigned Cybermen have discarded many of their limitations, exhibiting increased speed, rapid upgrading to overcome weaknesses, and the ability to convert any biological organism into their ranks.In the two-part finale of the 2014 series, "Dark Water" and "Death in Heaven", the Twelfth Doctor (Peter Capaldi) learns too late that the Cybermen have formed an alliance with a female incarnation of the Master, Missy (Michelle Gomez), who is converting the stolen bodies of the dead into an army.Cybermen are next seen in "Face the Raven" (2015), among the various alien refugees hiding in London, and in series finale "Hell Bent", in which a rusted Cyberman is imprisoned in the Cloisters of Gallifrey.The origin of another group of Cybermen is told in the two-part Series 10 finale "World Enough and Time" and "The Doctor Falls", when a Mondasian colony ship is stuck escaping the gravity of a black hole for many years.In "Fugitive of the Judoon", experienced companion Captain Jack Harkness (John Barrowman) sends a message to the Thirteenth Doctor (Jodie Whittaker): "do not give the lone Cyberman what it wants".However, the Master (Sacha Dhawan) intervenes, promising an alliance only to swiftly betrays Ashad, confiscating the Cyberium and converting the massacred Time Lord civilisation into "CyberMasters" – a new race of infinitely regenerating Cybermen.During this novel, the Sixth Doctor's new companion Grant Markham returns to his home planet and learns that a group of Cybermen have hidden on it for centuries, with his robophobia being based around the repressed memory of witnessing a Cyberman kill his mother before he escaped.They are mentioned in passing in Hinton's The Crystal Bucephalus, where the Cyberlord Hegemony is a peaceful future version of the Cybermen who have an empire in the Milky Way; their description was modelled after Banks's designs.They appear in Human Resources, which Big Finish produced for radio BBC 7 and subsequently released on CD, and sees the Eighth Doctor averting a plan to take control of a new weapons system.[10] In 2006/2007, the Trading Cards magazine Doctor Who - Battles in Time issues 8 - 11 ran a sixteen-page comic strip consisting of four linked stories featuring the Cybermen, written by Steve Cole, drawn by Lee Sullivan and coloured by Alan Craddock.The Cybermen in the revived series are usually constructed from human brains bonded to a Cyberman exoskeletal shell with an artificially-grown nervous system threaded throughout ("The Age of Steel"), although direct grafting of cyber-components is another method of conversion ("Cyberwoman").Lastly, when the first Cyber Leader is killed, his head explodes with some white liquid leaking down his body; there are references in that episode to a patented Cybus Industries mixture of chemicals used to preserve the brain.The masks and one-piece bodystockings were made from jersey fabric, with holes trimmed with vinyl where the Cybermen "eyes" and "mouths" were; the actors' features were darkened to hide their faces.Silver tape was added around the eye and mouth area for emphasis, and on Reid's instruction, the Lovells attached "hydraulic joints" consisting of tubing from a vacuum cleaner manufacturer and plastic practice golf balls.Millennium's Martin Rezard was the lead sculptor of a full-sized clay Cyberman, from which moulds were taken to create over forty fibreglass pieces to make up the head and body of each costume.[32] The sleeker and more elegant design introduced in "Nightmare in Silver" was made by the Millennium FX team from flexible polyurethane rubber, painted to look metallic using a new process originally developed for use in the car industry.The Doctor Who Role Playing Game "Cyber Files" worked around the contradiction by stating that in The Tenth Planet, the oldest designs of Cybermen were used for the attack while the later more sophisticated models remained on Mondas.Although the cloth-like masks of the first Cybermen were soon replaced by a full helmet, a similar physical effect involving the mouth "hatch" opening and then shutting when the line was finished was used until The Wheel in Space (1968).Later, the production team used special effects from its Radiophonic Workshop by adding first a mechanical larynx used by Peter Hawkins,[35] then a vocoder, to modify speech to make it sound more artificial.The Patients in "World Enough and Time" (Pre Mondasian Cybermen) communicated through speech synthesis keyboards, similar to those used in hospitals for people unable to talk normally or use their vocal cords.They wore grey surgical robes and their faces were entirely covered with cloth bags, save for a nasal canula that administered fluids and all were hooked up to IV drips.During the early stages of these experiments (a precursor to cyber-conversion), The Patients were shown to feel the pain caused by this process, with some even begging for death, twisting in their chairs and jabbing at their speech keyboards.In their first appearance in The Tomb of the Cybermen, they resembled oversized metallic silverfish and had segmented bodies with hair-like tactile sensor probes along the base of their heads, which were topped with crystalline eyes.In the Past Doctor Adventures novel Illegal Alien by Mike Tucker and Robert Perry, set in the 1940s, the Cybermen create cybermats by cyber-converting local animals like cats or birds, possibly because of lack of technological resources.
