The Dweller is 1 of the 4 RTA's left (Ranger Team Of America) , After being exsposed to highly amounts of radiation Chris Dweller's life was turned around to be a RTA! After killing and assassinating many people Chris Dweller's name was known all throughout America, leaving his name stranded to the place he used to call home... He now is a "Prototype" ZXv4 Which means his body parts are mechanical making him 300x times the man he used to be... His mask stays on because he is ashamed of what people might think after being exsposed to the radiation... But America was turned into a wasteland after the bombs fell... But The Dweller wasnt hurt by the radiation he was basically a god... He know holds a team of RTA's himself... Being the leader...
