Here are some images of Aurora/Monogram's 1/72 scale UFO from the television series "The Invaders"
The Invaders, a Quinn Martin Production (season one was produced in association with the ABC Television Network - or as it was listed in the end credits, "The American Broadcasting Company Television Network"), is an ABC science fiction television program created by Larry Cohen that ran in the United States for two seasons, from January 10, 1967 to March 26, 1968. Dominic Frontiere, who had provided scores for Twelve O'Clock High and The Outer Limits, provided scores for The Invaders as well.
Roy Thinnes starred as architect David Vincent, who accidentally learns of the secret alien invasion already underway and thereafter travels from place to place, trying to foil the aliens' plots and warn a skeptical populace of the danger. As the series progresses, Vincent is able to convince a small number of people to help him fight the aliens, most significantly millionaire industrialist Edgar Scoville (Kent Smith) who became a semi-regular character as of December 1967.
Neither the Invaders nor their planet were ever named. Their human appearance was a disguise; they were never shown in their true form except in one episode, "Genesis", in which an ill alien researcher loses his human form and is briefly seen immersed in a tank of electrified, salinated water. Unless they receive periodic treatments in what Vincent called "regeneration chambers", which consume a great deal of electrical power, they revert to their alien form. One scene in the series showed an alien beginning to revert, filmed in soft focus and with pulsating red light.
They had certain characteristics by which they could be detected, such as the absence of a pulse and the inability to bleed. Nearly all were emotionless and had "mutated" little fingers which could not move and were bent at an unnatural angle, although there were "deluxe models" who could manipulate this finger. There were also a number of mutant aliens, who experienced emotions similar to those of humans, and who even opposed the alien takeover. The existence of the Invaders could not be documented by killing one and examining the body: When they died (at least while in human form), their bodies would glow red and disintegrate — along with their clothes, any items they were carrying at the time and anything they touched when dying— leaving little more than traces of black ash. On several occasions, a dying alien would grab or otherwise make deliberate contact with a piece of their technology to prevent it from falling into the hands of humans.
The type of spaceship by which the Invaders reach the Earth is a flying saucer of a design derivative of that shown in the contestable early-1950s photographs of self-proclaimed UFO "contactee" George Adamski, but instead of having three spheres on the underside, the Invaders' craft has five shallower protrusions. It was a principle of the production crew to not show them with set and prop designs and control panels that were utterly alien from the conventional human ones (such as H.R. Giger would later present in Alien).
They use a small, handheld, disc-shaped weapon with five glowing white lights applied to the back of the victim's head or neck to induce a seemingly-natural death, which is usually diagnosed as a cerebral hemorrhage. They also employ powerful weapons to disintegrate witnesses, vehicles and - in one episode - a sick member of their own race whose infection's side effects was causing dangerous notoriety. Also in their arsenal is a small device consisting of two spinning transparent crystals joined at their corners which forces human beings to do the aliens' bidding.
