History:
High-school student Wally West's hero was the Flash, champion of Central City, and as the president of the Flash Fan Club in his hometown of Blue Valley, the biggest day in Wally's life came when his aunt, Iris West, arranged for him to go to Central City for a visit. Iris's boyfriend, Barry Allen, invited the boy over to his apartment to actually meet the Flash – an offer Allen knew he could make good on since, unknown even to Iris, he was actually the Scarlet Speedster.

As the Flash told Wally about the accident that gave him his powers, the very same circumstance befell Wally. While the boy stood in front of a cabinet of chemicals in Flash's lab, a lightning bolt struck the cabinet. Apparently, the same chemicals that had affected Barry Allen splashed over Wally as well, for Wally also gained the power to move at super-speed.

Flash made Wally his protege – Kid Flash – and Blue Valley's native super-teen enjoyed many adventures, not only solo, but with both Barry and with the Teen Titans. While he began his career, wearing a smaller version of Allen's costume, he shortly received a uniform all his own.

Eventually, Wally gave up his career after he discovered that he had developed a mysterious disease that would kill him if he continued to use his speed. He returned to action during Earth's great war against the Anti-Monitor, and a blast of energy directed toward Wally during the battle subtly altered his body chemistry. As a consequence, his disease went into remission, but his super-speed was greatly reduced.

During that same war, Barry Allen sacrificed his life to help save Earth from the Anti-Monitor. To honor his memory, Wally adopted Allen's costume and crimefighting name – though Wally chose to begin performing his heroic deeds for monetary reward. Coincidentally, as he swung back into action, he found his powers to be more and more unreliable. Wally's psychiatrist provided the answer when he theorized that, when Allen had unleashed the power of the matter transformer and changed Wally's costume, he had also inadvertently imprinted upon Wally another idle thought: that if Wally ever began using his powers irresponsibly, they would go away.

Shortly thereafter, they did disappear completely, though this time as a result of an alien gene-bomb unleashed on Earth by marauding invaders. With the aid of his friends, scientists Jerry and Tina McGee, Wally reconstructed the original accident that gave him his powers and, to some extent, restored them. While he isn't as fast as he was when a boy, Wally's speed is ever on the increase; it may yet someday be fully restored.

Wally no longer seriously protects his double identity, though it is not commonly known. Wally has, in recent years, developed quite a reputation as a womanizer.

Powers:
As Kid Flash, Wally West once possessed the ability to move at near-light speed and the power to control the molecules of his body, allowing him to vibrate through solid matter. Today, he has the following powers and limitations: Wally can move at about three times the speed of sound (roughly 2100 miles per hour). He has superhuman endurance, but must eat and sleep a great deal to compensate for the loss of energy that fuels his speed.

The Flash possesses an aura of unknown energy that protects him from friction heat and other adverse effects of moving at super-speed. That same aura absorbs the heat energy generated by Wally's abnormal metabolism, turning it into muscle power and using it to cleanse the tissues of the formic acids which cause muscle fatigue.

While Wally still has absolute power of his body's molecules, Wally is only now relearning how to control this power so as to pass through solid objects; whether he can still travel into other dimensions or through time remains to be seen.

Wally West is the third hero to fight crime using the name Flash.
