The Flash (Young Justice)

Flash (real name Barry Allen) is a superhero speedster from Central City and a founding member of the Justice League. He is the former mentor of his nephew, Kid Flash, and the "Fastest Man Alive". Barry is the second person to have taken up the identity of the Flash, the first being Jay Garrick.

Personality
Although not much has been revealed about Barry Allen, he has so far demonstrated to be one of the more approachable members of the Justice League. Laid back and witty, he takes every possible moment to talk. He has a habit of being late to important events, which often annoys Kid Flash to no end. He is kindhearted and well-mannered, something Wally's parents wish would rub off on their son as well.
