- "Welcome to my new empire, Doctor. It is fitting that you should be the first to fall to the power of the Daleks!"
- ―Davros about to fight The Doctor on Skaro in LEGO Dimensions
When Davros was little, he became trapped in a field of deadly hand-mines, creatures that resembled hands with eyes in the palm. The Twelfth Doctor arrived and attempted to save him by giving him his Sonic Screwdriver. However, upon realizing it was Davros, he abandoned him, although he later came back and rescued him with a Dalek gun from the future and left the Sonic Screwdriver with the young Davros.
Davros grew up to become the head of the Kaled Scientific Elite, developing new ways to fight the Thals. At some point he had an accident which led to him using a special wheelchair and an artificial eye. In attempting to save his people from mutating from the radiation from the Thousand Year war they had been fighting against the Thals, he accelerated the mutation process and placed the resulting mutant inside a life support machine/tank: the Dalek. The Fourth Doctor succeeded in delaying the Daleks development temporarily and Davros was seemingly exterminated by his creations, although his wheelchair simply placed him in suspended animation.
The Daleks revived him twice when their existence was threatened. Davros also attempted to create a new race of Daleks who would obey him. This led to a war between his Daleks, and those who obeyed the Supreme Dalek.
He was apparently killed in the first year of the Time War between the Time Lords and the Daleks, but was rescued by a Dalek who managed to break through the Time War's time lock. He created a new race of Daleks who were destroyed whilst attempting to destroy reality; Davros, however escaped and went back to Skaro to rebuild the Daleks.
In his old age and close to death, he summoned for the Twelfth Doctor, who was feeling guilty about abandoning Davros as a child. He tricked The Doctor into reviving himself and the Daleks with his regeneration energy. Following this, The Doctor went back in time and used a Dalek gun to save Davros from the hand mines.
In LEGO Dimensions, Davros attempts to invade Earth but is defeated by the Twelfth Doctor when he goes back in time and prevents it.
