The Doyle Fan Club was a fan club formed in 1987 by former Misfits members Jerry Only and Doyle Wolfgang Von Frankenstein.
It was made to promote their new band Kryst The Conqueror and stay in touch with fans of the Misfits, according to various interviews conducted at the time, and a series of fan club letters written by Jerry Only (as "Mo The Great") from 1987 to 1995. When the rights to the Misfits name was given over by Glenn Danzig in an out-of-court settlement, the Doyle Fan Club ceased to exist and was reinstated as the new official Misfits Fiend Club.
