The microbe swarm was a genetic chimera of two bacteria species; one a hydrophilic bacteria used as an experimental food preserver, the other an extremely rare silicone-based deep sea organism.
The microbe swarm appears as a large, semi-translucent, luminescent gelatinous mass. The swarm is greenish in color. It derives energy by breaking down water molecules, which it typically absorbs from other organisms. It is capable of draining the moisture from a creature within a matter of seconds, leaving nothing behind but a dried and dessicated corpse. They only known living swarm was sucked into a powered-up vaccuum cleaner and given to the U.S. government for study.
