Many works of fiction have featured UFOs. In most cases, as the fictional story progresses, the Earth is being invaded by hostile alien forces from outer space, usually from Mars, as depicted in early science fiction, or the people are being destroyed by alien forces, as depicted in the film Independence Day. Some fictional UFO encounters may be based on real UFO reports, such as Night Skies. Night Skies is based on the 1997 Phoenix UFO Incident. UFOs appear in many forms of fiction other than film, such as video games in the Destroy All Humans! or the X-COM series and Halo series and print, The War of the Worlds or Iriya no Sora, UFO no Natsu. Typically a small group of people or the military (which one depending on where the film was made), will fight off the invasion, however the monster Godzilla has fought against many UFOs.
