Henry and Nora Allen (parents, deceased), Malcolm Thawne (brother), Iris Allen (wife), Don and Dawn Allen (children), Bart Allen (grandson) and Jenni Ognats (granddaughter), Wally West (nephew) - see Allen Family for complete family tree Barry Allen is the second incarnation of The Flash, the fastest man alive.Using his super-speed powers, he taps into the Speed Force and becomes a costumed crime-fighter.His position is a legacy in the Flash Family, successor to the original Jay Garrick and predecessor to Wally West.He is a founding member of the Justice League of America. However, in actuality, he had been born healthy, but given to another family, the Thawnes, whose child had died during birth.Barry Allen and a twin brother were born two weeks late, to Henry and Nora Allen in the small midwestern town of Fallville, Iowa. The lateness of Barry's birth only foreshadowed his bad habit of always being late.Barry grew up reading the adventures of his favorite superhero, Jay Garrick, the original Flash and acted many of his hero's adventures out with his friend and future actress, Daphne Dean.
During one summer, Iris's nephew Wally came to visit her in Central City.He called himself the Flash, a tribute to his childhood idol He briefly considered wearing a costume that would show his face, like Jay had, but decided that it would be best to wear a mask to conceal his true identity.As the Flash, Barry later became a founding member of the Justice League of America, where he befriended Hal Jordan, the Green Lantern, with whom he had many adventures both with and without the Justice League.In high school, Barry had a reputation for being slow and easy-going. His date had wanted to put a little motion in his life, and they went on the roller-coaster first thing.Because of this, he developed a fear of roller-coasters, a fear that he didn't get rid of until much later in his life.
