In 1987, four years after the Misfits, Doyle and Jerry formed the metal band Kryst The Conqueror with drummer The Murp. Select songs from the album were released by Jerry Only's record label "Cyclopian Music" as an EP, and featured guest guitarist Dave "The Snake" Sabo of the metal band Skid Row.
In 1995 Jerry settled a legal battle out of court with co-founder Glenn Danzig, effectively allowing him rights to the bands name on a performing level. Doyle and Jerry reformed The Misfits in 1995, this time with Jerry acting as the band's figurehead and with Michale Graves as vocalist and Dr. Chud as drummer. The group released two full length albums of new material. In 2000 at a live show, Doyle unplugged his guitar and left the band.
In 2005, Doyle left New Jersey for Las Vegas, and began auditioning members for his own band, Gorgeous Frankenstein. In 2007, Gorgeous Frankenstein played their first tour, opening for Danzig. Doyle has since joined Danzig on several occasions to play 30-minute-long sets of classic Misfits songs.
In 2008 Doyle had one of his hand made, custom Annihilator guitars and a set of speakers auctioned off on eBay. The equipment was used live from 1996-2001 and sold for thousands of dollars.
After years of interest from Doyle and demands from fans, Doyle began releasing high-end standard guitar and bass versions of his Annihilator through October Guitars. In a partnership with Haunted Hot Sauce, Doyle is set to release a product line of his own.
Gorgeous Frankenstein set out to tour another set of dates for 2008. The band now includes Argyle Goolsby of Blitzkid fame on bass and vocals and Dr. Chud, formerly of the Misfits on drums.
Doyle claimed that a reunion effort with Glenn Danzig ceased further progression when "Jerry put a fuckin' monkey wrench in it. [In] 2002, we had meetings ... And [Jerry] kind of fucked it up, him and his manager. We were going to do a record, do a tour and everything."
