====Spin-offs (1980–present)====
Since 1980, ''The Executioner, Mack Bolan'' books and spinoffs - [[Able Team]], [[Phoenix Force (novel)|Phoenix Force]], [[Stony Man]], and [[Mack Bolan]] - have been written by [[Harlequin Books|Harlequin]]'s team of writers.  The Harlequin Gold Eagle books moved Bolan into a fight against [[terrorism]], in whose course he was given the cover identity of "Colonel John Macklin Phoenix." Since 1980, Harlequin has produced new novels, and the writer's name is mentioned on the copyright page as a provider of "a contribution" to the work, pushing the number of ''Mack Bolan'' novels into the hundreds; all of them bear the byline, ''Don Pendleton's Mack Bolan.''<ref name="Markert2016">{{cite book|last=Markert|first=John|title=Publishing Romance: The History of an Industry, 1940s to the Present|url=https://books.google.com/books?id=yV_TCwAAQBAJ&pg=PT177|date=26 February 2016|publisher=McFarland|isbn=978-1-4766-2124-1|pages=177–178|location=Jefferson, NC}}</ref>
