Title: Cyberman
Content:  The Cybermen are a fictional race of cyborgs who are among the most persistent enemies of The Doctor in the British science fiction television programme Doctor Who. Within the context of the series, the Cybermen are a species of emotionless space-faring cyborgs who, often painfully, surgically convert human beings (or other similar species) to join and populate their ranks. First appearing in 1966, the Cybermen were created by Dr. Kit Pedler (the unofficial scientific advisor to the show) and story editor Gerry Davis. The Cybermen have seen many redesigns and costume changes over Doctor Whos long run, as well as a number of varying

A mainstay of Doctor Who since the 1960s, the Cybermen have also appeared in related programs and spin-off media, including novels, audiobooks, comic books, and video games. Cybermen stories were produced in officially licensed Doctor Who products between 1989 and 2005, when the TV show was off the air, with writers either filling historical gaps or depicting new encounters between them and the Doctor. The species also appeared in the Doctor Who TV spin-off Torchwood, appearing in the fourth episode, "Cyberwoman" (2006).
Title: Rise of the Cybermen
Content:  "Rise of the Cybermen" is the fifth episode of the second series of the British science fiction television programme Doctor Who, which was first broadcast on BBC One on 13 May 2006. The episode introduces a terrestrial reinvention of the Cybermen, as well as a parallel universe which would serve as a recurring plot element in the series. It is the first part of a two-part story, the concluding part being "The Age of Steel", broadcast on 20 May. The episode is set in the parallel universe's version of London. In the episode, the businessman John Lumic (Roger Lloyd-Pack) seeks to "upgrade" all of humanity into Cybermen by placing their brains inside metal exoskeletons. The episode was directed by Graeme Harper, who became the first and so far only person in the show's history to have directed episodes in both the original and revived runs of the series: he previously directed the critically acclaimed serial The Caves of Androzani in 1984, and Revelation of the Daleks in 1985. The episode was the first Doctor Who story to feature the Cybermen in the show's 2005 revival. They last appeared 18 years prior in Silver Nemesis.
Title: The Tomb of the Cybermen
Content:  The Tomb of the Cybermen is the first serial of the fifth season of the British science fiction television series Doctor Who, which was originally broadcast in four weekly parts on BBC1 from 2 to 23 September 1967. In the serial, the time traveller the Second Doctor (Patrick Troughton) and his travelling companions Jamie McCrimmon (Frazer Hines) and Victoria Waterfield (Deborah Watling) get caught up in an expedition to the planet Telos, where the financiers of the expedition, Eric Klieg (George Pastell) and Kaftan (Shirley Cooklin) intend to revitalise the Cybermen that are buried in the underground tombs there in exchange for the Cybermen sharing their power. It is the earliest serial starring Troughton as the Second Doctor, as well as the only Cyberman story produced in the 60s, known to exist in its entirety. It also introduces the Cyber Controller and the Cybermats.
Title: Attack of the Cybermen

It was credited to the pseudonymous author "Paula Moore"; there are conflicting accounts concerning to whom this credit belongs. Beginning with this serial and continuing for the remainder of Season 22, episodes were 45 minutes in length (as opposed to previous episodes which were 25 minutes long); for syndication, in some markets, this serial is re-edited into four 25-minute segments. Attack of the Cybermen has a complex plot which reiterates narratives from

Content:  Doctor Who was revived after a long hiatus by new showrunner Russell T Davies in 2005. By then, development of CGI let script-writers include large numbers of Cybermen or Daleks in stories. In the first series of the revived programme, the Cybermen do not appear except for the inactive head of one, which is seen in a private museum of alien artefacts on Earth in the episode "Dalek". For Series 2 in 2006, Cybermen were reintroduced with a new origin story set in a parallel universe. In the "Rise of the Cybermen" and "The Age of Steel" two-part story, the Tenth Doctor (David Tennant)

The First Doctor (William Hartnell) opposes these Cybermen when they attempt to drain the Earth's energy to make way for Mondas' return to the solar system; in this encounter, Mondas absorbs too much energy from Earth, destroying it and all Cybermen on Earth. The adventure takes its physical toll on the Doctor, forcing him to regenerate for the first time, becoming the Second Doctor (Patrick Troughton). The Cybermen next appeared in The Moonbase (1967) opposite the Second Doctor. In 2070, the Cybermen attempt to remotely destroy the Earth by

The Fourth Doctor (Tom Baker) is next to encounter a group of Cybermen in Revenge of the Cybermen (1975). These Cybermen are depicted as the wandering remnants of a fallen empire, ravaged by the so-called Cyber-Wars against victorious humanity, which had exploited the Cybermen's weakness to gold. These Cybermen attempt to restore the glory of their race by destroying the gold-rich asteroid Voga. Cybermen were not seen again until Earthshock (1982), in which the Fifth Doctor (Peter Davison) encounters Cybermen in

No explicit reference is made to their origin, but generally the stylised 'c' (for Cybus Corporation) on their breastplate had been replaced by a plain circle, implying that they were not from the parallel universe. They appear in "The Pandorica Opens" (2010) alongside many of the Doctor's recurring enemies as part of an alliance dedicated to stopping him, arriving in cyber ships in 102 CE. They appear again in "A Good Man Goes to War" (2011), when the Eleventh 
Title: List of Doctor Who universe creatures and aliens
Content:  The original Cybermen were a race of humanoids originating on Earth's twin planet Mondas. As they implanted more and more artificial parts into their bodies as a means of self-preservation, they became coldly logical and calculating, with emotion all but deleted from their minds. The Cybermen also have a rivalry with the Daleks. In the two-part story "Rise of the Cybermen" and "The Age of Steel" of the second revived series (2006), the Cybermen originate on a parallel-universe version of Earth, where they were created by John Lumic, a genius obsessed with immortality. He forcibly 'upgraded' vast numbers of people in the parallel earth before a counter-revolution, initiated by the Tenth Doctor, started fighting back. The Cyberman concept was created by Dr. Kit Pedler (the unofficial scientific advisor to the programme) and Gerry Davis in 1966. Their first appearance was in the serial The Tenth Planet. They have since been featured numerous times in their efforts to conquer and convert humanity to cyborgs like themselves.
