As far as we can tell, the guy that built this place was considered the coolest of the cool, and taught other people how to be more like him.”— The King, Fallout: New Vegas
Elvis Aaron Presley was an extremely popular American singer of the 20th century. A cultural icon, he is widely known by the single name "Elvis." He is often referred to as the "King of Rock and Roll" or simply "The King."
His presence is more prominent in Fallout: New Vegas with references to his songs and movies in quest names as well as an entire gang known as The Kings who idolize Elvis and have styled themselves after him.
Ironically, not even The Kings themselves know of Elvis' name, henceforth why they simply called themselves the way they are.
- The King's School of Impersonation in the Mojave Wasteland is an Elvis impersonation school, where the Kings are centered. In addition, their leader, The King, is an Elvis impersonator.
- Developers were unable to obtain performance rights to Elvis' songs as they proved too costly. 
- Jason Bergman also commented that "We felt we were better off getting a wide variety of music than getting a single Elvis song."
