The Flash (Barry Allen)

Barry Allen is Central City's resident speedster, a superhero who uses his Speed Force abilities to protect its citizens as the fastest man alive when he's not working a forensic case.

Origin
When Barry was a boy, his parents' relationship wasn't going well, and while he prepared to participate in a spelling bee at school, his mother Nora was struggling to encourage him despite working double shifts and trying to get a divorce from his father Henry. He received the divorce papers on the day of the spelling bee, and because Nora had to work, he seethed and took Barry to school. When Nora returned from work, she was happy to see that her son had won the competition, but she was obligated to speak to Henry about their relationship, and so Barry was sent to the bookstore in the meantime. By the time Barry returned, however, his mother had been murdered, and his father had been placed under arrest, though he professed his innocence.

Fortunately, Darryl Frye, who had secretly been involved romantically with Nora, pulled some strings and was able to take Barry in. Having learned from Darryl that the search for evidence, in that case, would inevitably lead to the truth, Barry became a forensic scientist. For years, he visited Henry in prison, promising to look over all of the evidence of his mother's murder case until he found a way to prove his father's innocence. After years of coming back, and failing to find any proof, Henry broke down in tears and admitted that he had committed the crime. The shock of realizing that all of his efforts had been for nothing depressed Barry. On the night of a storm, Barry angrily tore his lab apart. Suddenly, a bolt of lightning crashed through his lab's window, and struck him in the chest, causing him to drop the chemical vials he was carrying, and douse himself.

After a 2 month long comatose period, Barry woke with super-speed abilities. Inspired by Darryl's example, Barry decided to take on a symbol for himself and fight for good. He created the ring that held his specially designed costume and became known as the Flash, the fastest man alive.

Early Heroism
After a week of saving Central City from petty crime, The Flash was called into action at STAR Labs where there was a reported break-in. Upon arriving, Barry realized that the supposed criminal, a boy named Charlie Sue, had superpowers like himself that he was unable to control. Yahweh, an alien parasite known as a Surgeon, broke out of his containment in STAR Labs and Barry was forced to join forces with Charlie Sue to eliminate the threat.

Barry and Charlie Sue raced to and from London, Barry being fast enough to complete the trip in 0.32 seconds. Barry mentions that he witnessed some sort of flying speedster who was so fast he was barely visible.
