Pyro (Marvel Comics)

Pyro is the name of two characters appearing in American comic books published by Marvel Comics.

The first character known as Pyro is St. John Allerdyce, a recurring enemy of the X-Men and later an agent of the U.S. government. He was created by Chris Claremont and John Byrne and introduced in The Uncanny X-Men #141 (January 1981) as part of the Brotherhood of Mutants. Pyro has the mutant power to control fire, but not create it. Pyro and the Brotherhood of Mutants are the antagonists in the X-Men story Days of Future Past as they attempt to assassinate Senator Robert Kelly, which in an alternate timeline leads to a dystopic future where Mutants are hunted, killed or captured by the Sentinel robots. The assassination is thwarted, and at a later date the Brotherhood become agents of the US government in exchange for a full pardon, and the team becomes known as the Freedom Force.

The second character known as Pyro is Simon Lasker, an American teenage mutant with the ability to create and control fire. Lasker was created by Marc Guggenheim and Ardian Syaf and introduced in X-Men Gold (Vol. 2) #1 (April, 2017). He was initially hypnotized by Mesmero into joining his Brotherhood of Mutants, but later joined the X-Men.

An Americanized version of Pyro named John Allerdyce appeared in the X-Men film franchise produced by 20th Century Fox. He was portrayed by Alexander Burton in X-Men (2000), and was subsequently replaced by Aaron Stanford for its sequels X2 (2003) and X-Men: The Last Stand (2006), and the Marvel Cinematic Universe (MCU) film Deadpool & Wolverine (2024).
