In the fourth volume of the Time War series, looking at the Eighth Doctor's role in the Time War, after The Valeyard uses a Dalek weapon to erase the Daleks from history, the Dalek Time Strategist escapes the erasure by travelling into a parallel universe where the Kaleds and Thals have been at peace for centuries, with Davros still fully human and married to a Thal woman. The Dalek Time Strategist manipulates this alternate Davros into using his dimensional portal technology to merge various alternate Skaros together to recreate the Daleks in the prime universe, convincing Davros that the Doctor is an enemy of the Kaleds rather than the Thals. Reference is made to the 'prime' Davros having been killed in the first year of the War (as mentioned in "The Stolen Earth"). The process of merging with his alternate selves causes the alternate Davros to gain the injuries and memories of his counterparts, to the extent that he forgets his wife and the peace with the Thals. Eventually his presence restores the Daleks in the prime universe, but the Dalek Emperor has Davros put into stasis to prevent his influence causing another civil war by causing the Daleks to become divided between loyalty to the Emperor and Davros.
