Motives[[edit] | [edit source]]
There were many motives for alien invasion. Some species invaded due to the destruction of their homeworld, (TV: Terror of the Zygons, Rose, The Parting of the Ways, Invasion of the Bane, The Day of the Doctor, et al.) or the rendering of their homeworld uninhabitable, (TV: The Tenth Planet, The Seeds of Death, et al.) whilst others invaded to expand their empires. (TV: The Christmas Invasion, et al.[additional sources needed]) One particular case had the Earth invaded as part of a plan to power a weapon. (TV: The Stolen Earth / Journey's End)
The Sontaran Commander Kaagh believed the common reason was that humans had "no guts", remarking that it was "no wonder" that half the species from Earth to the Verlixix Spiral Cluster had plans to invade the planet. (TV: Enemy of the Bane) The Twelfth Doctor, after hearing from a human that there was a horror movie called Alien, commented that with that "really offensive" attitude it was "no wonder everyone keeps invading you". (TV: Last Christmas)
Some unknown power, organisation, or person had classed invasions by type. A type F invasion was said to be aesthetically motivated. (PROSE: The Well-Mannered War)
