Radroach

Great American cockroaches, colloquially called radroaches or giant cockroaches, are giant versions of the pre-War species that have been mutated by atomic radiation.
Characteristics Radroaches are found mainly in underground areas and sewers across North America, which can cause them to be a pest in certain Vaults because they can usually be found in fairly large groups. They feed on the dead, but will go after living creatures if isolated. Their numbers are their biggest advantage. Radroaches live mostly in the areas east of California.
These radroaches are commonly seen in the dark, damp or irradiated parts of the wasteland and look similar to normal cockroaches, save for the fact that they have mutated to be the size of a domestic cat. They are generally little more than a nuisance to Armageddon survivors and less than likely to pose a challenge. Radroaches are territorial and rather aggressive, but not very harmful. Anyone can kill them with their bare hands, and will only attack when they feel threatened by passersby. Although they are winged, radroaches are not capable of flight. Still, it is possible that the wings are used for interspecies communication. Radroach innards are useful in the treatment of radiation poisoning and are widely used by tribals for this purpose.
