[4] Producer Philip Hinchcliffe told Friedlander to consider a design similar to the Mekon from the Eagle comic Dan Dare, with a large dome-like head and a withered body.
[8] In the serial Destiny of the Daleks, Davros is played by David Gooderson using the mask Friedlander made for Wisher after it was split into intersecting sections to get as good a fit as possible.
In an interview for Doctor Who: Unleashed, executive producer Russell T. Davies said that this is how Davros will be depicted in future appearances, to avoid contributing to harmful tropes of disabled villains in media.
As chief scientist of the Kaleds and leader of their elite scientific division, Davros devised new military strategies in order to win his people's thousand-year war against the Thal race that also occupies Skaro.
[17] In Destiny of the Daleks, it is revealed that Davros (now played by David Gooderson) was not killed, but placed in suspended animation and buried underground in the destruction of his bunker.
However, the Dalek force is destroyed by the Doctor, and Davros is captured and imprisoned in suspended animation by the humans, before being taken to Earth to face trial.
[19] In the Sixth Doctor story Revelation of the Daleks, it is revealed that Davros managed to escape at the end of Resurrection and has gone into hiding as "The Great Healer" of the funeral and cryogenic preservation centre Tranquil Repose on the planet Necros.
There, creating a clone of his head to serve as a decoy while modifying his body so that it can fire electric bolts and his chair is able to hover, Davros uses the more intelligent frozen bodies to engineer a new variety of white armoured Daleks loyal to him (while using the lesser intellects as food for the galaxy, ending a galaxy-wide famine), but he is captured by the original Daleks and taken to Skaro to face trial.
The episode reveals that Davros was thought to have died during the first year of the Time War, when his command ship "flew into the jaws of the Nightmare Child" at the Gates of Elysium, despite the Doctor's failed efforts to save him.
Under Davros' guidance, the Daleks steal 27 planets, including Earth, and hide them in the Medusa Cascade, one second out of sync with the rest of the universe.
[24] In the follow-up episode "Journey's End" (2008), it is revealed that the stolen planets are required as a power source for Davros' ideal final solution: the Reality Bomb, which produces a wavelength that would cancel out the electrical field binding atoms to reduce all life outside the Crucible into nothingness in both his universe and countless other realities.
[25] Davros returns in the two-part Series 9 opening "The Magician's Apprentice" and "The Witch's Familiar" (2015), having escaped the Crucible's destruction and ending up on a restored Skaro with his life being prolonged by the Daleks.
But when the aged Davros' health begins to fail, he remembers his childhood self, played by Joey Price, meeting the Twelfth Doctor (Peter Capaldi) during the Kaleds' thousand-year war prior to Genesis of the Daleks.
The young Davros finds himself lost on the battlefield and surrounded by handmines, with the Doctor throwing his sonic screwdriver to the boy with the intent to save him before learning his name and leaving the child to his fate.
Davros, seeking a final revenge on the Doctor, employs the snake-like Colony Sarff (Jami Reid-Quarrell) to bring him to Skaro.
But the Doctor reveals Davros' scheme has also revitalised the decomposing-yet-still-alive Daleks left to rot in Skaro's sewers, causing them to revolt and destroy the city.
[27] In the Children in Need sketch "Destination: Skaro" (2023) (which takes place during an earlier time in the Kaled-Thal war), Davros (Julian Bleach) (who has not yet become disfigured or received the cybernetic eye) is seen presenting a Dalek prototype featuring a robotic claw to his assistant, Castavillian.
When he briefly departs to attend to an urgent matter, the Fourteenth Doctor lands in the TARDIS, accidentally destroying the robotic claw.
He inadvertently suggests the name "Dalek" for the prototype, mentions its catchphrase of "exterminate" and gives Castavillian a plunger-tipped arm as a replacement for the broken claw.
Terry Molloy has reprised his role as Davros in the spin-off audio plays produced by Big Finish Productions, mostly notably Davros (taking place during the Sixth Doctor's era), which, through flashbacks, explored the scientist's life prior to his crippling injury, which is attributed to a Thal nuclear attack (an idea that first appeared in Terrance Dicks' novelisation of Genesis of the Daleks).
The Sixth Doctor manages to defeat his plans, and Davros is last heard when his ship explodes, an event obliquely mentioned in Revelation.
It takes place directly after the television story Revelation, while leaving the planet Necros and beginning Davros' trial.
At the end of the story, the self-destruct mechanism of Davros' life-support chair explodes after he is attacked by the Mechanoids, destroying an entire human colony.
By the time of the Eighth Doctor audio play Terror Firma (set after Remembrance), Davros is commanding a Dalek army which has successfully conquered the Earth.
However, Davros had previously recruited one of the Spider Daleks as a sleeper agent for just such an eventuality, and even he was not certain in the end if he was being disintegrated or being teleported away to safety, leaving the possibility open for his return.
Paul Cornell's dark vignette in the Doctor Who Magazine Brief Encounters series, "An Incident Concerning the Bombardment of the Phobos Colony" occurs sometime between Resurrection of the Daleks and his assumption of the role of Emperor.
In 2008, Julian Bleach appeared live as Davros at the Doctor Who Prom, announcing that the Royal Albert Hall would become his new palace, and the audience his "obedient slaves".
The BBC's 1993 Christmas tape parodied the allegedly robotic, dictatorial and ruthless management style of its then Director-General, John Birt, by portraying him as Davros taking over the BBC, carrying out bizarre mergers of departments, awarding himself a bonus and singing a song to the tune of "I Wan'na Be Like You (The Monkey Song)" describing his plans.
