A Radroach is a type of mutated insect, found throughout Equestria. When the megaspells fell they mutated and grew in size. Compared to other wasteland wildlife, they're barely considered a real threat, but they will not hesitate to attack a pony, especially in large numbers.

Radroaches continue to act like pests, much like their pre-war counterparts. They are usually found in great abundance, hiding in old pre-war ruins. They are fairly easy to kill, a pony can kill one just by stomping on it with their hooves.
