Humanoid Dalek

The Humanoid Daleks were a Skarosian species, who, after a discharge of neutron bombs, they mutated into the "machine Daleks".

Characteristics
These Daleks were short, under-developed blue-skinned humanoids with sparse white hair and disproportionately large heads. One of these Daleks, Yarvelling described the machine Daleks as a thousand times more intelligent than himself and his ally, Wolfian.

History
The Daleks originated on Dalazar, situated across the Ocean of Ooze from the home of their enemies, the Thals. The Daleks had a pacifist leader, Drenz, who the warlord Wolfian personally murdered publically in order to, with Yarvelling, a chief scientist start use neutron bombs on the Thals and use the new Dalek war machines against the survivors. Two weeks after the factories of Dalazar commenced production of the war machines, a meteorite strike set out a fire in the factories which spread and caused the detonation of the neutron bombs.

Over the course of two years, radiation mutated the survivors. One used a war machine as transport, making himself into the first "machine Dalek". When Yarvelling and Wolfian emerged from their fallout shelter, the machine Dalek set them to work on production of more war machines until they died of radiation sickness. (DC: Genesis of Evil)

In the time of the Dalek Empire, the Daleks found three pre-war humanoid Daleks in suspended animation and revived them. (DC: Legacy of Yesterday)

Behind the Scenes
The history of the humanoid Daleks does not mesh very well with other accounts of the creation of the Daleks. Only this account describes the ancestors of the Daleks as also calling themselves Daleks, as opposed to Kaleds or Dals. Possibly, however, following the events of Genesis of the Daleks, the Kaled race mutated and turned into the humanoid Daleks. Yarvelling may have come across Davros's old plans for his Daleks or possibly actual Dalek remains. This would not explain, however, why the humanoid Daleks and the Thals seem to exist on two separate continents, a fact not mentioned in any other story.
