After developing for 7 years as subterranean larvae, adult thunderbugs—ornery, armored, and bison-sized—claw their way to the surface in search of food. They migrate in herds, stripping plains bare of plantlife and crops, and their distinctive chirping and bellowing strikes fear into farmers' collective hearts. (If molebears and karkadillos didn't keep the thundergrub populations down, the Mutant Future would certainly be overrun.)
Thunderbugs do double damage after Charging.
Traders, armorers, weaponsmiths, and artisans pay hefty prices [as determined by the Mutant Lord] for thunderbug "hides" and "ivory". And Yinsects have been rumored to utilize the creatures as mounts.
