The Nemetrix symbol is on a red belt on its waist.

Powers and Abilities

Feralscreech can emit a type of gas that scrambles a Vulpimancer's sense of smell.

Feralscreech can emit a specific high-pitched frequency that can paralyze Vulpimancers, making them unable to move without feeling intense discomfort.

Due to not having any eyes, Feralscreech navigates areas through echolocation. It can determine the location of objects in the environment by use of reflected sound waves.

Feralscreech's teeth and claws are sharp enough to cut through metal.

Feralscreech is strong enough to carry a Vulpimancer off the ground.

Feralscreech can use its wings to fly.


Feralscreech is weak to frequencies higher than that emitted by it.




Feralscreech's name references its feral nature as well as its high-frequency screech.
