The Roach King is a random encounter you may come across in the Capitol Wasteland. He is located North-East of the Minefield and directly West of the Temple of the Union, due North of the Regulator HQ. The Roach King Throne is made up of tires, a regular chair, a clock and a playground rocket as usually found on pre-War playgrounds.
Originally, The Roach King was randomly generated to be either a female or a male "raider", which would occasionally cause him to become a female with facial hair. In this mod he will not change gender and has more improved stats making him a lot more challenging to engage with. He is also outfitted with a special helmet which improves your perception by 2 points when worn.
His Radroach companions are slightly stronger than the average radroach.
(This mod also fixes a vanilla bug that would randomize the Roach King as female with facial hair.)
