"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, allowing him to switch various soldiers in Napoleon's army with his own Daleks, ultimately intending to replace Napoleon with a Dalek after Waterloo is won so that he can change history and lead humanity in a direction where they may ally with the Daleks. The plan is complicated when the Sixth Doctor arrives and uses the device to swap bodies with Davros in an attempt to subvert the Daleks' plans from the inside, but Davros-in-the-Doctor is eventually able to convince the Daleks of his true identity, planning to remain in the Doctor's healthy body while leaving the Doctor trapped in his original form. At the end, Davros and the Doctor are returned to their original bodies with the aid of the Doctor's new companion Flip Jackson, the Doctor exposes Davros's true agenda to Napoleon, and Davros is left with an army of Daleks who have had their minds wiped. These Daleks presumably become the "Imperial Daleks", first seen in "Remembrance of the Daleks".
