The Phantom Glitch

DIRECTORY GLTC-8870 OBJECT CLASS  FATAL 

Encounter Procedures
In any situation where GLTC-8870 is spotted, a broadcast of a potential Spock Wave must be prepared. This object cannot be drawn with Glitch Energy, so instead direct use of military-grade weapons are required to eliminate the glitch. All audio recordings of GLTC-8870, regardless of quality, must be immediately destroyed.

Description
GLTC-8870 is an extremely mobile Glitch capable of moving at speeds relative to normal humans. As a result, during Spock Waves, it is usually one of the first FATAL-class glitches to arrive. Observations have shown that they typically sort into groups of no more than 2. GLTC-8870 instances are completely devoid of GLTC-152-A ("Glitch Rust"), and are instead covered in the same material that makes up their cranium. GLTC-8870 is much more intelligent than HAZARDOUS-class glitches, and is capable of easily navigating fortified structures.

GLTC-8870 produces a fairly loud sound of about 70 dBs; it has been described to sound like a low-pitched masculine chorus. Listeners of this sound, about 40 minutes after exposure, will begin to experience intense seizures and subsequently death within 3 minutes.
