Brood Symbiots are tiny Broodlings, no larger than a meter tall, who can steal control of any weak willed being she keeps her hand on. These Broodlings are pilots and slave drivers of the Brood.
The common Brood Symbiot is one part taskmaster while being an animal wrangler and rider. Symbiots can take even the most docile creature and command it for war; stealing its will and driving it to acts of violence it would never do otherwise.
Symbiots love any animal; the more trusted and loved the better. This makes them far more frightening and confusing when they are turned on their former masters.
Players who choose to play a Brood Symbiot should always keep in mind that they are always seeking new prey; to feed upon or to make into a new slave for the Brood. The stranger the creature the Symbiot finds better. If it proves truly useful to the Brood a Mutator may even create hundreds more so every sister can have one.
