Flash, real name Barry Allen, is a superhero who primarily relies on his super speed.
Born to Henry and Nora Allen, Barry Allen is a forensic scientist with a reputation for being very slow, deliberate, and frequently late, which frustrates his fiancee, Iris West. One night, as he is preparing to leave work, a lightning bolt shatters a case full of chemicals and spills them all over Allen. As a result, Allen finds that he can run extremely fast and has matching reflexes. He dons a set of red tights sporting a lightning bolt, dubs himself the Flash (after his childhood comic book hero, Jay Garrick), and becomes Central City's resident costumed crimefighter. Central City University professor Ira West (Iris' adoptive father) designed Allen's costume (reminiscent of the original Fawcett Captain Marvel) and the ring which stores it while Allen is in his civilian identity. The ring can eject the compressed clothing when Allen needs it and suck it back in with the aid of a special gas that shrinks the suit. In addition, Allen invented the cosmic treadmill, a device that allowed for precise time travel and was used in many stories. Allen was so well liked that nearly all speedsters that come after him are often compared to him. Batman once said "Barry is the kind of man that I would've hoped to become if my parents hadn't been murdered."
