The character :
the name of several superheroes appearing in comic books published by DC Comics. Created by writer Gardner Fox and artist Harry Lampert, the original Flash first appeared in Flash Comics #1 (cover date January 1940/release month November 1939). Nicknamed the “Scarlet Speedster”, all incarnations of the Flash possess “super speed”, which includes the ability to run, move, and think extremely fast, use superhuman reflexes, and seemingly violate certain laws of physics.
Thus far, at least four different characters—each of whom somehow gained the power of “the speed force”—have assumed the mantle of the Flash in DC’s history: college athlete Jay Garrick (1940–1951, 1961–2011, 2017–present), forensic scientist Barry Allen (1956–1985, 2008–present), Barry’s nephew Wally West (1986–2011, 2016–present), and Barry’s grandson Bart Allen (2006–2007). Each incarnation of the Flash has been a key member of at least one of DC’s premier teams: the Justice Society of America, the Justice League, and the Teen Titans.
The series :
an American superhero television series developed by Greg Berlanti, Andrew Kreisberg, and Geoff Johns, airing on The CW. It is based on the DC Comics character Barry Allen / Flash, a costumed superhero crime-fighter with the power to move at superhuman speeds. It is a spin-off from Arrow, existing in the same fictional universe. The series follows Allen, portrayed by Grant Gustin, a crime scene investigator who gains super-human speed, which he uses to fight criminals, including others who have also gained superhuman abilities.
