Here's a scene I've rendered out today after plugging away at this old model. Buzzers home is the deep forest in which they collect metallic remnants from eras past, constructing vast caverns of bizarre and futuristic hives deep underground. These three buzzers are out scouting for ship wreckage for a new addition to the hive!
Yes I am just being imaginative here. The film never went so deep into character history and origin. In fact the film never even came out! But one day, perhaps it will. Buzzers are easily agitated and very swift, they have a high level of intelligence and even have developed an ability to read minds, but they don't understand most of what they pick up which evolution will need to cause adaptation to if it is to be of any use.
All things creative.
