Scorchbeast

Scorchbeasts are creatures found in Appalachia in 2102.

Background
Beneath the entirety of Appalachia is a vast colony of these draconic bat horrors. After a period of time, the colony becomes overcrowded and the Scorchbeasts dig to the surface to destroy settlements and devour humans, leaving large rifts in the landscape. The only way to shut the rifts is to launch one of the few remaining nuclear I.C.B.M.s from one of their silos scattered across the map, collapsing it and killing those that remain. This is only a temporary measure, as the scorchbeasts will once again overpopulate and breach the surface somewhere else after a period of time, necessitating repeated strikes by vigilant humans to prevent the surface from being fully overrun.

Scorchbeasts are also apparently responsible for the partial creation of the Scorched, as according to research by Vault 76's overseer, their underground colony contains the fungus responsible for the crystalline growths seen on the scorched.

Biology
An enormous mutated bat-like monster with a humanoid body, pointed ears and membranous wings, allowing it to fly and soar through the air. Strong and aggressive, it attacks with razor-sharp teeth, claws, and a powerful sonic blast capable of shattering wood and metal structures.

Appearances
Scorchbeasts appear only in Fallout 76.
