Davros

Davros was a brilliant Kaled scientist crippled by radiation, he developed the Daleks from specially-bred mutations of the Kaled race. Totally devoid of pity or moral conscience he helped the Thals to kill his own people when the future of the Daleks was threatened. Created in Davros's own image, the Daleks attempted his extermination, but lacking his creative abilities, the Daleks reluctantly tried to rescue him. Following two resurrections, Davros struggled to eliminate the Movellan threat and regain dominance over his creations.    

Davros has had many different appearances he slowly wiped out all of his human features; here are some of the different types.

Davros appeared in Genesis of The Daleks, Destiny of The Daleks, Resurrection of The Daleks, Revelation of The Daleks, Remembrance of The Daleks
