The Gravitational Beam Emitter, often abbreviated as GBE, is the iconic weapon of Killy in the Blame! manga.



The initial origins of the Gravitational Beam Emitter are unknown, though it is heavily implied to predate the City itself. It appears to be a Safeguard weapon, as numerous agents are seen using instances of them, but they are known to have been used by the earlier members of the Silicon Creature's cult.

It is known throughout the entire City, feared by some and coveted by others.

Killy does not seem to remember where he aquired it, though Sanakan claimed that he stole it from the Safeguard forces at one point.

May have been invented by the same creator of the gravitational swords.



Fires condensed graviton energy.

Unlike most weapons, the GBE does not seem to run out of ammunition, as it appears to draw it's power from the user itself. Because of this, the gun has a form of limiter installed on it, preventing it from using too much energy and killing the user; this limiter can be deactivated by the user if they choose to do so.

Despite it's basic appearance, it's inner mechanisms are apparently incredibly complex; so much so that even the Bio-Electric Corporation, one of the most advanced companies known in the City, could never figure out how to replicate it.
