You may be looking for Dalek War Machine.

The Mark I was the name given by Davros to a Travel Machine prototype, the casing of the first Dalek that he created. It was an experimental life support unit modeled after his own chair. Besides the transplanted Thal brain, it included a life support matrix, an optical stalk, feeding tubes and was activated by a power conduit with only 92% distribution. (AUDIO: Guilt) According to the Dalek Combat Training Manual, Davros abandoned this prototype and then his next model before settling upon the Mark III travel machine. (PROSE: Dalek Combat Training Manual)

According to another account, Davros' chair was the Mark I, and his initial designs were the Mark IIs. (PROSE: The History of the Daleks) Another account had Davros present an early prototype machine before he had constructed his own advanced chair, after which he unveiled Dalek One. (PROSE: Davros Genesis) In any case, the Daleks were later perfected by Davros in the Mark III Travel Machine. (TV: Genesis of the Daleks)

Davros' claims to have designed the Daleks' travel machines were later contradicted by the Daleks themselves under the command of the Dalek Prime, who instead claimed that he had stolen the designs from other scientists and then passed them off as his own. (PROSE: War of the Daleks) Indeed, in one account, the very first Dalek casings were originally the "Dalek War Machines" designed by the scientist Yarvelling for use in the war against the Thals before the mutated Daleks claimed them as protection against the harsh conditions of the devastated, irradiated Skaro. (COMIC: Genesis of Evil)


Meeting a young Davros before the accident that scarred him, the War Master realised the ideas of what would one day become the Dalek travel machine were "already forming in [his] head". (AUDIO: From the Flames)

The first Mark I Travel Machine created by Davros hosted the brain of Baran, a captured Thal spy. (AUDIO: Guilt)
