Kraff is a fictional deity from the Grand Theft Auto video game series, specifically appearing in "Grand Theft Auto V." As the central figure of the Epsilon Program, a satirical portrayal of religious cults, Kraff is depicted as an extraterrestrial being who visited Earth billions of years ago. Followers of the Epsilon Program believe that Kraff’s teachings lead to enlightenment and financial prosperity, although the group is widely considered to be a parody of real-world cults. The Epsilon Program adds a layer of humor and social commentary to the game's narrative, reflecting Rockstar Games' characteristic approach to satire.
