Doctor Who: Galaxy 4(1965)

Doctor Who: Galaxy 4 is a classic science fiction serial in which the Doctor, Vicki and Steven land on a barren planet and discover two alien species stranded after a space battle. The beautiful Drahvins appear civilised at first, but they're actually cloned soldiers ruled by the ruthless matriarch Maaga. The grotesque Rills, by contrast, prove to be intelligent and peaceful explorers. As the Doctor uncovers the truth about each species, he must navigate the moral complexities of the conflict and decide whom to trust. The serial subverts expectations about appearance and nature, challenging assumptions about who deserves aid and sympathy in a desperate situation.
