The Reality Destroyer we call RA is hiding somewhere on Earth, probably deep underground.
Starting as a single molecule less than one-hundredth of a millimeter wide, it remains a fully capable annihilation system.
Fortunately, its previous incarnation was over 99% destroyed by our Ally's counterattack, and it is presumably in recovery mode.
By now, it will have constructed a new nano-brain to plan the next stage of its mission.
A suspected time-loop entity, its only purpose is to cause its own creation as soon as possible. To this end it stimulates the development of certain robot technologies. In a way, we are all a part of RA.
It can control people through human brain functions we didn't know existed, creating irresistible compulsions, terrors, and paralysis as needed.
It created the sliver-thin, ten gram attack robot made of diamond wires that killed six thousand people in less than ten minutes in Tokyo last month. We were very lucky that time.
When it recovers, it may create and control a temporary particle swarm entity, a smart gas matrix, or an energy imbalance electro-ghost. The only way to fight a nanocloud would be with another nanocloud.
Fortunately, the attacker has been consistently countered by our Ally, our unknown helper who may yet defeat and destroy RA, without whom we would already be dead.
Eventually, we may have to fight it by ourselves.
First we must find RA. We are Earth's immune system.
Our mobile agents now number in the hundreds. They are still human, but should be considered as expendable as white blood cells. Sacrifices must be made!
To be ready for the decisive moment, each antibody will now be equipped with a one-megaton demolition charge.
