Davros (Unbound Universe)

In a parallel universe, Davros was a Kaled scientist who created the Daleks on Skaro during the Kaled-Thal War. However, after coming to believe that the Daleks could never achieve his vision for them, he betrayed his creations to serve the Quatch Empire as their Chief Technician, oblivious to the Quatchs' role in the Kaled-Thal War.

When he returned to Skaro decades after leaving, Davros assisted the Quatch in their second attempt to conquer Skaro for the dimensional energy located at the planet's core. However, after the Doctor of this universe revealed to Davros the Quatchs' role in igniting the war that lead to Davros creating the Daleks, Davros betrayed the Quatch and exacted revenge on them, forcefully sending them back to their native dimension - an act which cost him his life.

The Kaled-Thal War
During the Quatch Empire's first attempt to conquer this universe's Skaro, Davros worked as a scientist for the Kaleds, and was severely mutilated and crippled after a Quatch attack (although Davros was completely unaware of the Quatch's responsibility for the attack), forcing Davros to use an advanced life-support chair to survive. Eventually, the Kaleds attempted to shut down Davros' experiments; he responded by betraying his people to serve the Thals instead.

Davros was ultimately responsible for ending the Kaled-Thal War that was provoked by the Quatch after they failed to conquer Skaro. Davros did so by creating the Daleks, although unlike his N-Space counterpart, Davros created two types of Daleks. One race, who Davros later referred to as "the Renegades", were effectively identical to the Daleks his N-Space counterpart created, lacking any degree of pity or mercy. These Daleks attempted to murder Davros, and eventually abandoned their creator and Skaro to conquer the universe. However, the second Dalek race retained a concept of pity and mercy, albeit in a heavily distorted form, as part of Davros' attempts to create a race of Daleks that were strong and intelligent, but remained loyal to their creator. Davros spent years confined to the Dalek City, working on the Daleks; during this time, he also created the first Black Dalek, who served as Davros' conduit to the City.

Abandoning his creations
However, over the years, Davros came to believe that he could never develop the Daleks to perfectly achieve his original vision for them. Eventually, Davros was contacted by the Quatch, who had learnt of him after encountering some of the Renegades, and desired to recruit Davros, due to fearing that he would perfect the Daleks and make them even more powerful than the Quatch; Davros, disappointed by his "children", accepted the Quatch's invitation to join their empire, although he remained unaware of the Quatch's true reasons for recruiting him, or of their involvement in the stokings of the Kaled-Thal War. Davros discreetly left Skaro in a small spaceship to join the Quatch, without informing the Daleks first, and ultimately spent decades serving as the Quatch Empire's Chief Technician. During this time, Davros augmented the machinery used by the Quatch that stabilised them in Davros' universe, although he also secretly incorporated a means of shutting down the stabilisers to banish the Quatch back to their native dimension in case they betrayed him.

Following Davros' departure from Skaro, the Daleks loyal to Davros also left Skaro to find their creator, who they believed had gone on a "spiritual quest".

The second Quatch assault
Davros finally returned to Skaro, decades after he left, with the Quatch, after the latter had captured some of Davros' loyal Daleks and made preparations for a second attack on Skaro. After the Quatch mothership landed in the hub of the Dalek City, Davros teleported to the Thal incubation laboratory after two Quatch also teleported in and extinguished the fire that Alistair Gordon Lethbridge-Stewart and Nadel had started. Desiring to avert the conflict between the Daleks and the Quatch, as well as restore the Daleks to his original vision for them, Davros ordered the Quatch to take Alistair and Nadel to a holding cell, along with any Daleks the Quatch found; however, he remained undecided as to whether to convert the Thals into Daleks, or to simply exterminate them all in revenge for their ancestors' actions in the Kaled-Thal War.

Having ordered for the Daleks to be disarmed but kept alive to potentially be reprogrammed to serve the Quatch, Davros travelled to the Dalek hub and confronted the disarmed Black Dalek. He was alarmed to learn that the current Black Dalek not only mistook him for an imposter, but that the Daleks had recently begun a civil conflict on Skaro, after a Dalek claimed to be Davros and went rogue, causing the Daleks to fight over whether to serve the Black Dalek or the Dalek claiming to be Davros. Furious that the Daleks had returned to Skaro to protect the Thals, Davros explained to the Black Dalek why he left Skaro and the Daleks behind, before revealing his intention to propose a deal with the Daleks: those who were still loyal to their creator would be allowed to survive if they served the Quatch Empire, while those who did not accept these conditions would be exterminated. The Black Dalek, unable to argue against Davros, broadcasted across all of Skaro, informing the Daleks of Davros' return, with Davros himself confirming that the Dalek claiming to be Davros was defective and disillusioned. The Black Dalek also explained Davros' terms, and Davros ordered for all Daleks still loyal to their creator to go to the Dalek City for reprocessing into servants of the Quatch Empire.

Following the broadcast, Davros forced the Black Dalek to comply to reprocessing, before reporting to the Quatch that, as he had predicted, only a few hundred Daleks had travelled to the hub of the Dalek City for reprocessing. Unfazed, Davros, having updated the Quatchs' data banks with information gathered by their exploratory force's initial attack against the Daleks, ordered the Quatch to commence their attack on the Thal City once they were ready, before he began working on reprocessing his remaining loyal Daleks; while doing so, Davros observed the initial defeat of the Quatch in their first attack wave against the Daleks, before requesting the Quatchs' assistance in transporting some of his equipment to his advanced laboratory on the Quatch mothership.

Later, in his laboratory on the Quatch mothership, Davros began reprocessing the Black Dalek, disabling the Dalek's motor functions temporarily in the process; when the Black Dalek regained consciousness, it questioned why it was now loyal to the Quatch Empire, with Davros then angrily ordering it to never question such loyalty again. He eventually finished reprocessing the Black Dalek, installing several failsafes into the Dalek to ensure its loyalty to the Quatch, at the cost of somewhat more limited capacity for intelligent thought. Davros contacted some of the Quatch and explained the Black Dalek's conditioning to them when the Dalek arrived and announced its loyalty to the Quatch Empire.

Learning the truth
When the Doctor of this universe, Alistair and several Daleks began storming the Quatch mothership after landing a Dalek saucer outside the mothership, the Quatch contacted Davros and asked if he was protected; Davros stated that he had the Black Dalek, shortly before the Doctor, Alistair and several Daleks broke into Davros' lab and temporarily rendered the Black Dalek unconscious. After convincing the Daleks and Alistair to continue fighting the Quatch, the Doctor confronted Davros personally, and eventually inputted the data he, Alistair, Toloc and the Daleks acquired after interrogating a Quatch prisoner into Davros' systems, revealing to Davros the Quatch's role in Skaro's history, as well as them causing Davros' crippled state and igniting the Kaled-Thal War that led to Davros creating the Daleks.

Enraged, Davros decided to betray the Quatch and finally achieve his revenge. He revealed to the Doctor the existence of his secret system that allowed him to forcefully disable the machinery stabilising the Quatchs' presence in Davros and the Doctor's universe, thereby sending the Quatch back to their native dimension. Believing that the Quatch remained unaware of this failsafe, Davros gave the Doctor a brief window of time to escape the Quatch mothership, intending to stay behind and deactivate the Quatchs' machinery himself, aware that the resultant vast instability would likely tear the mothership apart. The Doctor thanked Davros, before escaping the mothership with Alistair and the remaining Daleks.

Shortly after, the Black Dalek briefly reactivated; Davros apologised to it abandoning the Daleks and allying with the Quatch, but would redeem himself with one last action. Davros then ordered his computer to deactivate the Quatchs' stabilisers, forcefully sending the Quatch back to their native dimension; he proudly declared that, although this scenario was not how he envisioned the end of his life, he felt that it struck "the appropriate note". The instability of dozens of Quatch returning to their native dimension then destroyed the Quatch mothership, killing Davros and the Black Dalek.

Legacy
Shortly after the Doctor, Alistair and the Daleks that infiltrated the Quatch mothership returned to the Thal City following the mothership's destruction, the Doctor informed the Daleks who had fought alongside Gillen, Nadel and the other Thals that Davros was responsible for ending the Quatchs' invasion of Skaro, and had sacrificed himself in the process to save his loyal Daleks.
