Enepay is encountered during the mission"For Purely Scientific Purposes", in which he, along with Kosumi and Hinto, meet with Nastas, Marston, and Harold MacDougal under the pretense of MacDougal interviewing them for his research. After a brief exchange of words in which the outlaws express their contempt for the condescending MacDougal, Enepay personally kills Nastas as a "traitor" for working with the Bureau of Investigation. John then guns down Enepay and his companions in revenge.
Outside of missions, Enepay may sometimes be encountered if the player attains a bounty for criminal acts in West Elizabeth. He will then join a posse and pursue them as a bounty hunter.
Enepay, along with Marshal Leigh Johnson, is one of the few characters seen to be dual wielding revolvers in the game.
He wears a U.S. Army revolver ammo belt, likely stolen or scavenged from one of his victims.
His name comes from the Lakota language, where it means "Brave".
Originally, Enepay, alongside Helaku, Kosumi, Nashoba, and Hassun, was intended to be a bounty target before the idea was scrapped during development.
He is one of a few Dutch's Gang members to wear tribal war paint. In his case, there are two white handprints on his vest.
Like all members of Dutch's Gang, Enepay does not appear in Free Roam.
Enepay wears 2 white feathers on the back of his bandana. These white feathers are also seen worn by the other unnamed member of Dutch's Gang. Except the unnamed member wears his feathers at the top of the back of his bandana, as so they stick up straight. Enepay's feathers lay flat on his hair.
