In the most literal sense, the Bouncer is a biological weapon: it is in fact a living creature. They were discovered in the Gamma 5 Sector near the Drathonian homeworld. They're unremarkable creatures, roughly the size of a cat. However, upon inhaling oxygen, it reacts with the chemicals in their digestive system to produce a small-scale explosion. This makes them lethal weapons in any environment Terrans choose to inhabit. To keep the Bouncers from premature detonation, they are fitted with masks and bound into a tight ball-shape. When a button upon the mask is pressed, it activates the 4-second timer for release. If the blood of a Bouncer comes into contact with human skin, it acts much like phosphorous, but is much more deadly. It will kill nerves upon contact, and will eat through bone in just under five minutes. It is ineffective upon Terran armor, but will eat through fabrics easily. It can be neutralized with water or saline. It is best to supply a saline injection to anyone whom comes into contact with the bodily fluids ASAP.
