Anyway, another one of the ideas was that the subspace crisis also wrecked havoc on the Borg hive mind, causing the Borg to go insane. Drone growth rampaged out of control, they ceased to strive for "perfection", and such. Anyway, this (finally getting to the picture) is what I envisioned an Insane Borg hunter drone would look like:
The idea goes that the first stage of the Insane Borg life cycle has them assimilating a host, just as they did in Voyager... the second stage, however, focuses on the removal of pretty much all of the organic body parts of the host, ultimately resulting in a drone that is almost entirely machine (as you can see in the picture, the deformed skull of the drone is left, along with the chest cavity and some of the leg tissue). Senses are replaced, however... the elongated structure above the skull handles sight, sound, taste, smell, etc.
Anyway, I've been working on this intermittently for several months, and I finally finished it. Just thought people would like to see it.
