The Thals are mentioned, but not shown, in the "TV Century 21" Dalek comic strip story "Genesis of Evil" (1965). In the narrative the Thals are stated to be a peaceful race, originally inhabiting the continent of Davius, who are at war with the Daleks; short, aggressive, blue-skinned humanoids who inhabit the continent of Dalazar. The Daleks plan to use a neutron bomb against the Thals but a meteorite storm detonates it prematurely, causing planet-wide destruction in which the Thals apparently perish.
