Davros is an archenemy of the Doctor and is the creator of the Doctor's deadliest enemies, the Daleks.

Davros is a mad scientist from the planet Skaro whose people, the Kaleds, were engaged in a bitter thousand-year war of attrition with their enemies, the Thals.

Davros is a megalomaniac who believes that through his creations, the Daleks, he can become the supreme being and ruler of the universe.

When he first encounters the Fourth Doctor in Genesis of the Daleks, Davros is the chief scientist of the Kaleds, one of two native sentient races of the planet Skaro.

Davros is the head of the Elite Scientific Division, created to devise new military strategies in order to win the war.

Davros realizes that contamination from the nuclear and biological weapons used in the war is mutating the Kaled race, and artificially accelerates the process to examine the ultimate evolutionary end product.

However, the Dalek force is destroyed by the Doctor, and Davros is captured and imprisoned by the humans in suspended animation, before being taken to Earth to face trial.

Davros can now fire electric bolts from his hand, although the hand is shot off shortly before his original creations arrive to defeat the new Daleks and transport Davros to face trial on Skaro.

By this time, Davros has been physically transplanted into a customised Dalek casing and is only revealed as the Emperor in the final episode.

However, a Dalek on the bridge of Davros ' ship reports that the Emperor's escape pod is being launched and a white light is seen speeding away from the ship moments before its destruction, leaving a clear route to bring Davros back in the future.

In earlier episodes, Davros is referred to ( albeit not by name ) twice: first in the episode " Dalek " by the Ninth Doctor, who explains that the Daleks were created by " a genius ... a man who was king of his own little world ", and again by the Tenth Doctor in the episode " Evolution of the Daleks ", where he refers to the Daleks ' creator as believing that " removing emotions made a race stronger ".

Davros is then shown in " Fear Her ," in a drawing on Chloe's wall.

Though Davros talks about his " new empire ", he at one point in time has actually been overthrown by his creatures and is kept prisoner in the Vault, being used for his scientific knowledge.

Davros now has a mechanical hand which is capable of firing electricity.

However, Davros has been betrayed by Dalek Caan, who having come to the realisation of the evilness of his race after seeing the entirety of time due to his temporal shift, is using his prophecies and influence to cause the Daleks ' destruction.

Thus the Doctor is forced to leave Davros to his fate as the Crucible self-destructs.

Speaking with the Emperor, the Doctor addresses him as Davros, but the Emperor responds " Who is Davros?

Davros proved too effective a character to be kept dead and was resurrected four years later in 1979's Destiny of the Daleks ( played by David Gooderson using the mask Friedlander made for Wisher-the mask had to be split into sections and rejoined to get as good a fit as possible ).

However, for instance, Big Finish was no longer allowed to use the character of Davros following his return to the series in 2008, although this ban has been lifted and Davros returned to Big Finish in The Curse of Davros, released in January 2012.

By the final episode, he had mutated into a tyrannical character reminiscent of Doctor Whos Davros ( though " just different enough not to infringe any copyright laws ").

Padbury has appeared in Doctor Who audio adventures from Big Finish Productions, first as a character other than Zoe in the full-cast audio Davros, and then as Zoe in Fear of the Daleks, part of the " Companion Chronicles " talking book series.

* Davros — the character

In the Fifth Doctor story Resurrection of the Daleks, a small Dalek force aided by human mercenaries and Dalek duplicates liberates Davros ( now played by Terry Molloy, with a new mask designed by Stan Mitchell ) from his space station prison, needing his expertise to find an antidote for a Movellan-created virus that has all but wiped them out.

Davros emerges as " The Great Healer " of the funeral and cryogenic preservation centre Tranquil Repose on the planet Necros in the Sixth Doctor story Revelation of the Daleks, where he uses frozen bodies to engineer a new variety of Daleks loyal to him, distinguished from the original Daleks by their white and gold livery and slightly changed design.

Davros as the Emperor Dalek, from Remembrance of the Daleks.

Davros was pulled out of the Time War by Dalek Caan despite it being time-locked, and bred a new Dalek race using cells from his own body, so that he has little skin and flesh left on his chest and his ribcage and internal organs are visible.

" The Doctor initially assumes Davros's personality has been totally subsumed, but in the later strip " Emperor of the Daleks " (# 197-202 ) this Emperor is shown as a different entity from Davros.

Set prior to Remembrance of the Daleks in Davros's timeline, but after in the timeline of the Doctor, the latter, accompanied by Bernice Summerfield, together with help from the Sixth Doctor, ensures that Davros will survive the wrath of the Daleks so that he can assume the title of Emperor, allowing history to take its course.

The Curse of Davros begins with Davros and the Daleks working together to try and alter the outcome of the Battle of Waterloo using technology that Davros has created that allows him to swap peoples ' minds, with matters becoming more complicated when the Sixth Doctor uses the device to swap bodies with Davros in an attempt to subvert the Daleks ' plans from the inside.

In The Juggernauts, Davros is on the run from the original Daleks.

Physically this resembles the Resurrection Gauntlet from Torchwood and Davros ' gauntlet from the Series 4 finale, but this may be coincidental.

Skaro appears in the Big Finish Doctor Who audio stories The Mutant Phase and Davros ( where we learn that Skaro had two moons: Falkus and Omega Mysterium, names drawn from a chart of Skaro's solar system in a 1976 Marks and Spencer tie-in book-Falkus is there revealed to be an artificial planet created by the Daleks as a last refuge ), and was where the Emperor Dalek operated from in The Genocide Machine, and features prominently in the I, Davros spin-off series, looking at Davros's life and the events that led to him creating the Daleks.

" Exterminate, Regenerate " is a song released by UK " Trock " band Chameleon Circuit and mentions Skaro from the prospective of Davros.

Davros is a Big Finish Productions audio drama based on the long-running British science fiction television series Doctor Who.

* The serial was one of the first British productions to make use of a Steadicam ; due to the high cost of such a set-up, nearly all the props and sets were reused, including the Davros mask.

He is best remembered for having played Davros, the wheelchair-using scientific mastermind and creator of the Daleks, in the British science-fiction television series Doctor Who.

It takes place directly after the television story Revelation, while leaving the planet Necros and beginning Davros ' trial.

This was the last appearance of Davros and the Daleks in the original run of Doctor Who ; after a brief appearance in the 1996 television film the Daleks would return in the 2005 episode " Dalek ".

However, the Daleks return in " Bad Wolf "/" The Parting of the Ways " ( 2005 ), and subsequently in " Army of Ghosts "/" Doomsday " ( 2006 ), " Daleks in Manhattan "/" Evolution of the Daleks " ( 2007 ), " The Stolen Earth "/" Journey's End " ( 2008 ) and " Victory of the Daleks " ( 2010 ), the penultimate of these being the series 4 finale where Davros also returns, and the final of these being the first time the Eleventh Doctor meets the Daleks.

Skaro's final appearance in the classic series ( in the chronology of the Doctor Who universe ) is in the story Remembrance of the Daleks, in which the Seventh Doctor tricked Davros and his " pure Imperial Daleks " into stealing the Hand of Omega.

Other spin-offs include the Gallifrey series ( with Lalla Ward as Romana, Louise Jameson as Leela and John Leeson as K-9 ); the Dalek Empire series ; the UNIT series ; the Iris Wildthyme series starring Katy Manning ; the Sarah Jane Smith series and the I, Davros series.

* The 2006 four part audio series I, Davros depicts Davros ' early life, from his childhood, right up to a few weeks before Genesis of the Daleks.

K-9 also makes appearances later in the game as does Davros, creator of the Daleks in the TV series, as the final end of level boss.

Later in the series when Davros is revived, he decides to take over the leadership of the Daleks himself, resulting in a schism within the Empire with one faction remaining loyal to the Dalek Supreme and another faction serving Davros.

* This story influenced the production of the four part Big Finish series I, Davros.
