Martians

The stories of little green men from Mars are true... to an extent. While the Martians are surely green, they are by far not little. And they also have little to do with the other pictures in popular fiction. Martians are actually plant people!

Description
Martians can be male or female, and their life cycle resembles closely that of plants, with the big difference that they do not root into the ground. They have a complicated social structure and a highly developed civilisation. However, they do not exist in their true form any more. When the evil Raxachk poisoned all of Mars with a deadly plague, their plant bodies all died. Also later attempts by Prektesh to create plant bodies that are immune, failed, since the plague had seeped into the soil.

Today all Martians live in robot bodies disguised as humans on Earth.
