"The Flash" debuted in 2014 after introducing its protagonist, Barry Allen, in a backdoor-pilot episode of "Arrow." Barry is a forensic investigator with a tragic past who gains superhuman speed and other powers during an accident at a particle accelerator. As he works to gain control of his powers, he also finds himself digging deeper into the tragedy of his family's past and learning the truth about what happened on the night that changed his life.
"The Flash" is still running on The CW as of 2022, with the ninth season already ordered.
