Klytode android

The Klytode Androids were used by the Klytode in an attempt to destroy the Earth by exploding them at weather control stations around the world. Their destruction would have led to the release of toxin bombs destroying the planet. When the Doctor points this out, the Androids rebel, not wanting to die. They turned on the Klytode and helped secure his capture and restraint on Earth. (DWAM: Return of the Klytode)
