Classic Era
The Daleks first appeared in the 1963 serial The Daleks, where they are depicted as the inhabitants of a city on the planet Skaro. In the past, they had engaged in a nuclear war with the Thals, the other native species of Skaro, which forced the Daleks into their city, which they are unable to leave due to a dependency on static electricity. The First Doctor's (William Hartnell) companion and granddaughter Susan Foreman (Carole Ann Ford) attempts to negotiate peace between them and the Thals, but the Daleks seek to kill the Thals. The Doctor stages an uprising, with the Thals seemingly killing the Daleks as their static electricity power supply is knocked out.
