The Bal'Kars Primary Weapon!

This would be better known to people as a "Particle Beam" Emitted from the mouth of the creature.

The Beam may be separated from their common surrounding. This can be accomplished by thermionic emission or arc discharge From the Mouth. The mouth Focuses Positrons into an energy ball. The positrons are exhaled from its breath and can be seen as a green mist that billows from the mouth and Naturally collect and condense into a ball in front of the monsters face where The Bal'Kar Can take aim, the Tentacles on the head then Release Electrons into the ball that thrusts it forward into a beam Traveling near the speed of light.
Charged beams may be further accelerated by use of high resonant from the Controllers Psywaves.

It does not hurt to fire the beam but they Feel Incredibly Drained after use...it feels like their guts have been sucked out (in a painless way) and the recovery time can range from 1 - 3 mins.

The general idea of such weaponry is to hit a target object with a stream of accelerated particles with high kinetic energy, which is then transferred to the molecules of the target Where they are ripped apart and then join in the continuation of the beams acceleration through the target. The power needed to project such a high-powered beam of this kind surpasses the production capabilities of any standard battlefield powerplant within the hive. So the Bal'Kar must gradually gather the energy atmospherically within the tips of the Head tentacles which act like high powered battery's. Charging generally takes a few days. You can normally tell when they are charged, because they glow brightly, exerting electrical pressure.
