Bzzomb

Bzzomb is an enemy most frequently found in Agnisort.

Alpha Lore (unlocked by killing Alpha variants)
Originally designed as a Floral Assistance Unit.

Meant to support the dwindling organic bee population in their sacred duties of pollination and occasionally stinging obnoxious children, one manufacturer dared to dream a bit bigger. The result was the first Bzzomb model, which, thanks to the Home Security Freedom Act of 2034, could technically be sold as a "consumer-grade floral assistor and home defense unit."

Beta Lore (unlocked by killing Beta variants)
The Bzzomb line of entirely-too-large-robobees is exactly like the original FAUs of old, except for the massive stinger, the on-contact explosions, the target-insensitive motion sensors, and a complete inability to participate in the pollination process in any meaningful way. The line was not a commercial success.

Gamma Lore (unlocked by killing Gamma variants)
Bzzombs are basically flying exploding garbage bots, but thanks to initial demand projections for residential exploding bees overshooting reality by a substantial margin, Control was able to acquire their supply at an unbelievably fair price. They're completely useless in every way, but they make great aerial target practice for new Contractors, and thanks to their wildly overcosted design, their solar-powered insides grant a daily operating cost of approximately zero dollars.
