John Lindley Byrne (born July 6, 1950) is a British-born Canadian American author and artist of comic books. Since the mid-1970s, Byrne has worked on nearly every major American superhero.
Byrne's better-known work has been on Marvel Comics’ X-Men and Fantastic Four and the 1986 relaunch of DC Comics’ Superman franchise. Coming into the comics profession exclusively as a penciler, Byrne began co-plotting the X-Men comics during his tenure on them, and launched his writing career in earnest with Fantastic Four (where he also started inking his own pencils). During the 1990s he produced a number of creator-owned works, including Next Men and Danger Unlimited. He also wrote the first issues of Mike Mignola's Hellboy series and produced a number of Star Trek comics for IDW Publishing.
Byrne’s original work has been noted as being rough, with his drawings emphasizing curves over straight lines. Byrne has himself called the straight line "his least favorite artistic element". Ron Goulart has called Byrne’s artwork "an eminently acceptable mix of bravura, complexity and storytelling clarity". In Scott McCloud’s book Understanding Comics, Byrne is charted along with other comics artists in the "Big Triangle". McCloud’s placement of Byrne within it identifies his style as similar to Gilbert Hernandez and Jim Lee, making the point that Byrne’s line style is naturalistic without being overly detailed.
