CONTROL BUG aka SPY BUG
The Control Bugs are a species of Arachnid that gains control of human hosts and forcibly changes their ideas and beliefs to that of the Arachnids.
Control Bugs are small, roughly the size of human hands. They seize control of a host by attaching themselves to the spinal cord, becoming a telepathic conduit for Brain Bugs. The range of their telepathic abilities has never been tested in the field. While having very little offensive capability on their own, they are very agile and difficult to hit with weapons.
They are first encountered on Tophet, controlling the Skinnies.
Control Bugs enter through human cavities and orifices, for example the mouth; they then burrow right into the brain and control a person’s mind. Although a victim initially appears fine and well, their health will gradually worsen due to the bug using them for sustenance. When control bugs have consumed their host to near death they are either removed or remove themselves before attempting to spread their offspring, beginning the process of infection all over again.
The only reported instance of these bugs being used was at Hotel Delta 1-8-5, where they attempted to reach the Federation high command by infecting General Jack Shepherd, who could then bring the infection to the Federations leaders and cripple humanity’s ability to fight.
The first-known infected human was Technical Sergeant Ari Peck, whose infection spread all around Hotel Delta 1-8-5 except to three humans.
