The Flash

The Flash is a comic book superhero from DC Comics. Created by writer Gardner Fox and artist Harry Lampert, the original Flash first appeared in January 1940. Four different characters each of whom somehow gained the power of "super-speed"—have assumed the identity of the Flash: Flash (Jay Garrick)|Jay Garrick, (1940–present), Flash (Barry Allen)|Barry Allen (1956–1985, 2008–present), Wally West (1986–2006, 2007–present), and Bart Allen (2006–2007, 2009–present).

The second incarnation of the Flash, Barry Allen, is generally considered the first hero of the Silver Age of comic books and the superhero has remained one of DC's most popular ever since. Each version of the Flash has been a key member of at least one of DC's premier teams: The Justice League of America.

The Flash has been the subject of comics books, cartoons, two television series (2014 CW Series and 1990 CBS Series), and is in the 2016 movie "Batman v Superman: Dawn of Justice" and 2016 movie "Justice League".
