After witnessing his mother’s supernatural murder, Barry Allen is taken in by Detective Joe West and his family. Barry becomes a brilliant but socially awkward crime scene investigator for the Central City Police Department. A particle accelerator malfunctions, bathing the city center with a radiation during a thunderstorm, and Barry is struck by lightning. Awakening after a coma, he discovers he can move at superhuman speeds. Harrison Wells, the accelerator’s designer, describes Barry’s nature as “metahuman”. Barry vows to use his gifts to protect Central City. As the Flash, Barry also pursues his mother’s murderer, the Reverse-Flash.
