Dalek mutant

Kaled mutants are the mutated descendants of the Kaleds of the planet Skaro. Enclosed in protective armour and weaponry, they became the Daleks. They wree mounted in the upper part of the Dalek machines.

Physical appearance
Kaled mutants varied in appearance. Their young were globular, soft and shapeless with tendrils or tentacles (DW: The Power of the Daleks, Genesis of the Daleks). Even the young were quite lethal and capable of strangulation with their tentacles. (DW: Genesis of the Daleks)

Some were eyeless and green and tentacled (DW: The Five Doctors, Resurrection of the Daleks). Others were pale blue with one eye (DW: Dalek). The Dalek Emperor during and after the Last Great Time War was purple-blue with one eye. (DW: The Parting of the Ways)
