Brain Slug

Brain Slugs' Spies 

These parasitic creatures are able to burrow into the human brain and destroy it in the process, somehow managing to mimic and replace its functions so that it can trick the body into thinking the brain is still in place and sending out signals. Though it is unclear exactly how the creatures do this, they are able to keep the body alive through the process while also being able to lay a selection of eggs inside the hosts' cranium.

FIRST APPEARANCE
1.04: Reprieve

DATA

 * Are physically weak and possess no armour
 * Once outside of a host body they move slowly, about what would be expected from what appears to be a gastropod mollusk.
 * Named after their ability to "control" the hosts' brain and manipulate them as if a puppet (in actuality the Host brain is dead and devoured in mere moments after infection)
 * Seem to be sensitive to electrical energy, and exposure to electrical devices can cause minor hemorrhaging (usually from nose or ears) from host.
 * Brain-worms that are hatched inside the host's brain will exit via the nearest orifice when safe from detection or forcefully if needed.
 * Each Slug seems to possess its own intelligence, rather than some sort of shared consciousness.
 * It is unclear exactly how the Brain Worms get inside the host body, but it is rumoured it is a process that involves Stalkers
