The MB-3 is a micro aerial drone the size of an actual mosquito, equipped with a hollow proboscis capable of penetrating exposed skin and delivering a micro-dose of pharmaceutical compound directly into the bloodstream. The unit flies with a wing-buzz frequency matched to local insect populations, making it aurally indistinguishable from a real mosquito. The injection feels like a mosquito bite — a minor irritation that targets brush off without a second thought.

Lazarus developed the MB-3 for 'targeted pharmaceutical delivery in field conditions' — administering vaccines, antivenoms, and emergency medications to patients who cannot be reached by conventional medical personnel. This is a real capability that saves real lives in disaster response scenarios. It is also a capability that allows the silent, deniable injection of any substance into any person without their knowledge or consent.

The MB-3's micro-dose capacity limits the range of effective payloads — it can't deliver enough volume for most fast-acting poisons. But it can deliver enough for slow-acting toxins, tracking compounds that mark a target's blood chemistry for identification, mood-altering pharmaceuticals, and — most insidiously — compounds that interact with specific BCI models to create exploitable vulnerabilities. The target scratches the bite, forgets about it, and never connects the minor irritation to the cascade of symptoms that follows days later.
