A Nanosect was a tiny robotic bee-like insect that was deployed in swarms from Nano-Swarmers hives. Like many insects, they moved towards light. They traveled in swarms and stung whatever their hive's laser light fell on with their pyrocidic stingers. With enough nanomites, the Nano-Swarmers upgraded into the Toxic Swarmers, and the nanosects were modified to contain an injection of deadly Zanifarian Death Weasel venom.
