The mysterious power known as the Speed Force is an energy field that has, over the centuries, granted incredible powers of velocity to certain heroes. The most famous of these is the Flash, also known as the Fastest Man Alive. Ever since the days of World War II, there has been a man clad in red who can run at impossible speeds, using his power to save lives and defend those who cannot defend themselves.

In the 1940s, college student Jay Garrick acquired his super-speed abilities in a random lab accident and became the first Super Hero to go by the name the Flash. Years later, Jay was succeeded by police scientist Barry Allen, who got his powers when during an electrical storm, a bolt of lightning streaked through a window, shattered a chemical cabinet and covered Barry in the electrified chemicals.

Wally West, Barry and his wife’s nephew, was also in an Identical Lab accident, like his uncle, and gain the same powers. He took the code name Impulse and became the Flash’s partner. Barry was the Flash for many years, until he was thought to have died. Impulse took up the mantle soon after. But, when Barry returned, he became the Flash once again. All three generations of speedsters have been cornerstone members of both the Justice Society and Justice League.

The Flash has mastery over not just speed, but time itself, and he has often used his powers to travel though different eras and even into other dimensions. Although the Flash has not always been fast enough to outrun personal tragedy when it has come for him, he always does his best to prevent the same from happening to the people of Central City and Keystone City.
