The Boar, also called simply fiend, is a mutated pig, employed by the mutants as a sort of watchdog. Boars are often found hanging around patches of radiation, which does not damage them, but instead heals them. It is covered in a hard shell of crystalline protrusions, which protects it from small arms fire. Fiends attack infantry with a powerful bite attack which injects mutagens and causes mutation. Against vehicles and buildings, the Fiend is able to generate discharges from the crystals on its back.
