Cerberus xenobiologists believed that until recently that the Collectors were coordinated by a biologically active caste, similar to other insectoid alien species. New evidence suggests the Collectors have a singular commander, a so-called "Collector General" that has never been seen on the battlefield. Instead, it selects its minions as remote platforms for its consciousness in a process that has been likened to a biological hack or a cybernetic version of demonic possession.
The Collector General can send a secure signal to any one of its minions, smoothly take control of their motor functions, and awaken their previously dormant biotic potential. In a matter of seconds, even the lowliest Collector drone can be upgraded to a battle-hardened biotic commander. If the Collector dies, the General can simply activate and control another body.
Postmortem analysis reveals that this "command signal" relies on cybernetic implants directly installed in the Collectors' cerebellums, but how the technology functions is presently unknown. Coordinating sensory input and motor functions simultaneous with remotely amplifying biotic abilities is beyond the grasp of current human science. Why such an advanced species would be interested in humans is puzzling. More disturbing still, victims of the Collectors say the General has spoken to them and referred to itself by a human name: Harbinger.
