The Zoltans were a humanoid race native to Zolta. Zoltans were emotionless and identical in appearance, lacking necks or ears, and had short, bristly red hair.
In the 1970s, a Zoltan research expedition arrived at Mars at the time as an international team of Earth astronauts was exploring the planet. One astronaut, Adrian Fairley, crashed on Mars but his broken body was discovered and repaired by the Zoltans. The peaceful contact between the two species was made public on Earth and led to a worldwide media frenzy, with many people enthusiastically welcoming the Zoltans. Secretly, the Zoltans were using Fairley to breed Zoltan soldiers to eliminate prominent anti-Zoltan persons, facilitating their colonisation of Earth. After Fairley's death, a later visit to Mars found that the Zoltans had left. (PROSE: Soldiers from Zolta)
