The Flash

In 1940, writer Gardner Fox (1911–1986) and artist Harry Lampert (1916–2004) created the Flash for All-American Comics, which published under the DC Comics label. With powers and costume inspired by the Greek/Roman god Mercury, Jay Garrick made his debut in Flash Comics #1. Edited by Sheldon Mayer (1917–1991), the series featured the Flash, Hawk man, and a rotating cast of other heroes.

The flash is know for his lighting speed & to be able to run faster than superman himself. He was first know to battle against racketeers, kidnappers, or thieves until he joined the justice league with the other superheroes.The Flash proved so popular he gained a series of his own, All-Flash Quarterly in 1941 (soon shortened to just All-Flash), and a regular spot in Comic Cavalcade in 1942.

He was portrayed in smallville TV series Code name: impulse aka the flash - Bart Allen in smallville 2004 episode “Run. Member of the justice league.

The Flash’s Powers

The key ability all Flashes share is speed: running fast, thinking fast, kicking and punching fast. They can create whirlwinds with their arms or drill through the ground. They can move back and forth so quickly they become invisible. They can run up the side of a building faster than the pull of gravity, or across water before their feet have time to break the surface. Most of them have complete control over their molecules, and can vibrate through solid objects. The third Flash, Wally West, can lend speed to moving objects or steal it from them, slowing them to a stop.
The second Flash, Barry Allen, learned how to travel through time using his control over his molecular vibrations. On his own it was hit-and-miss, so he built the “cosmic treadmill” to help pinpoint destinations. By running on the treadmill, any Flash can set up the right vibrations to travel through time. Wally West is the only Flash (so far) to master time travel without the treadmill, though he avoids it whenever possible.
