especially the 2014 television series The Flash, while Ezra Miller portrays the character in the DC Extended Universe films Batman v Superman: Dawn of Justice, Suicide Squad, Justice League, the director's cut Zack Snyder's Justice League, the HBO Max series Peacemaker and will return in the upcoming 2023 film The Flash. Publication history The Flash (Barry Allen) first appeared in print in Showcase #4 (October 1956). The creative team on Showcase #4 was Julie Schwartz, editor; Robert Kanigher, writer, Carmine Infantino, penciler (illustrator); Joe Kubert, inker (assistant illustrator). Robert Kanigher is on record as saying he still considers Gardner Fox as "the creator of The Flash" and his creation of Barry Allen is a reworking of that original work. As a result, no one name is easily identifiable as the "creator" of The Flash (Barry Allen). Fox's superhero, "The Flash" first appeared Flash Comics #1 in 1940. In this story the man in the costume (he wore no mask) was named Jay Garrick. He rose in popularity and appeared in three comic book titles. After World War II, superheroes declined in popularity, causing many of the Flash's comic book series to be canceled. All-Flash was canceled in 1948 after 32 issues. Flash Comics was canceled in 1949 after 104 issues. All-Star Comics was canceled in 1951 after 57 issues, marking Garrick's last Golden Age appearance.

In the wake of these changes, publishers began introducing superhero stories again (as preferable to crime and horror), a change that began with the introduction of a new version of DC Comics' The Flash in Showcase #4 (October 1956). In 1956, DC Comics reinvented the Flash character, giving him a new costume, name, and background. This new Flash, named Barry Allen, was completely unrelated to Jay Garrick. In fact, Garrick had never existed, as far as the new books were concerned. Barry Allen's first appearance shows him reading a copy of Flash Comics, lamenting that Garrick was "just a character some writer dreamed up". Readers welcomed the new Flash, but still
