This is a bacteria that shuts down your respiratory system. It is the main plot point in The Labyrinth episodes.
Koflax was developed in a laboratory in Russia. Whether it had any other purposes is unknown, but it fell into the hands of Mr. Grote, who intended to use it as a form of biological terrorism. Though Koflax is normally an airborne bacteria, apparently in substantial amounts it can be compressed into a solid form. Mister Grote took advantage of this knowledge to enact his plan. He made supposedly "antique" vases out of Koflax, and coated them in lacquer that would dissolve at room temperature, thus allowing the Koflax to be dispersed in the air and kill everyone at the British Museum. In the end, the plot was foiled by Jason Whittaker and his allies.
