Nrak

The Nrak are a sapient species of alien vegetation which can produce parasitic spores to infect humanoid and non-humanoid hosts and take over their minds, assimilating other creatures as part of their gestalt intelligence.

Biology
The Nrak life cycle starts with a mouse-sized mobile seed stage, which needs to be in contact with alien enzymes to germinate. After being eaten and passing through the digestive track of an alien species, such as a Remoolian, the seed will germinate into a giant flower-like sessile organism which produces clouds of airborne parasitic spores. These will attack any life form they come in contact with and take over their bodies.

Those infected by the Nrak are linked in a hive mind and speak in a single voice, as their original personalities are suppressed and their minds absorbed by the collective. Nrak hosts can also transform themselves physically, such as by growing roots and increasing in size. They have no individuality of their own and live only to serve the Nrak.
