Feral ghoul

Feral Ghouls are Ghouls that have lost their ability to reason and have become aggressive.

Background
Also referred to as mindless zombies, ghoul crazies, ferals, and feral necrotic post-humans, prejudice against non-feral ghouls by Humans is due to the widespread assumption that a feral state is the inevitable condition of every ghoul. Feral ghouls are irradiated human beings that have experienced brain degeneration. Feral ghouls have no body heat and emit lethal levels of radiation.

According to Three Dog and Diamond City security, ghouls prefer dark areas, often underground or under the cover of the night sky. Feral ghouls screech when enemies are nearby, and attack using their hands. Some feral ghouls, such as those in Camp Searchlight, utilize weapons. They usually do not attack non-feral ghouls and may flee combat. Wearing a Ghoul mask will fool feral ghouls, making them remain non-hostile.

Some feral ghouls have lost their ability to communicate but are non-hostile, including Meat, Ethyl, Atom's Champion, and Sun of Atom.
