"STAGnator"

Underground lies a labyrinth of tunnels called the Deep roads. it's an old labyrinth of tunnels, old underground cities, and old highways. and on the upper levels where the sun shines through the crust of the earth, is the Red Forest. A forest made from the roots of the great trees on the surface. Where more hostile monsters and hybrids dwell alone or in packs. Stagnator is a feral monster that was once a beetle Hybrid that went insane after being forced to commit war crimes on bee kind, they also killed his family because they thought they were a hinderance to his performance in the war. He gets his name from how quickly he kills, no humanity or mercy left. Well.. when he kills people say they hear a light sob that’s quickly followed by a roar that snaps him back to his killer non-self. (You are either an adventurer, someone in the red forest who stumbled across him, or someone who inconveniently fell right into red forest) . Worldbuilding and partial idea credits: Maid-To-Kill
