Radscorpion queen

The radscorpion queen is a creature found in the Mojave Wasteland.

Locations
There are two radscorpion queens in Fallout: New Vegas. The radscorpion queen is twice if not triple the size of the giant radscorpion. One is found during the quest Wheel of Fortune, in the Camp Searchlight Fire Station, and the other is found in an unmarked location south of the Nipton Road Pit Stop, named Scorpions Burrow. Take caution: along with the queen, five other scorpions, ranging from small radscorpions to giant radscorpions are found guarding her. There are also two dead wastelanders, one Jackal gang member, and one prospector found inside the burrow containing various loot.

Appearances
The queen radscorpion appears in Fallout: New Vegas. As they have only been seen in Fallout: New Vegas it is possible they don't exist in Washington D.C(although this is quite unlikely, as radscorpions would have to be born someway else).
